3Introduction to debugging

Leveling feed The leveling mechanism in the machine is mainly composed of feeding roller (guiding and feeding roll), guiding roller (tracting and driving the material roll to feed at a certain speed) and leveling roller. Among them, the function of leveling the coil material is the leveling roller in the right picture. In this example, it is an upper 3 lower 4 structure. For rolls of different materials, different thicknesses, and different hardness, other equipment is also equipped with an upper 2 lower 3 structure or no leveling structure (for example, the G550 material used by LG has a relatively hard hardness, and the roll can still maintain a good flatness, so no leveling mechanism was added to the design).           Figure1-1 Leveling Structure Schematic Pre-punching and pre-shearing The function of the pre-shearing is to trim the end of the material roll to ensure that the end of the material roll is even, and the pre-shearing can also be cut to length according to production requirements. The advantage of pre-shearing is that there is no waste material and the shearing speed is fast. The disadvantage is that it cannot produce short materials and the shape of the plate is easy to open.(Slab shape opening: the opening means that the verticality of the profile section is greater than 90°, which is beyond the required range of the plate shape.   Figure 1-2 The Structure of Pre-punching and Pre-shearing    The lip changes from the forming angle of the A1-A5 process. For CZ machine, due to the different materials and specifications of the products, the passes of A pass are different (there are also 4 passes or 3 passes, etc.), or the same passes, but there is a slight difference in the angle of each pass change. Height molding is divided into two steps: preliminary molding and final molding. Preliminary molding is carried out in channel B, generally forming to 60°-70°, the specific forming angle and the change angle of each pass are the same as the principle of channel A, which is determined according to the product material, plate thickness, etc., and there are slight differences.      During the forming process of the B channel, when the height is formed to a certain angle, if the angle of the roller continues to increase, the lip will interfere and collide with the upper roller. C/Z transformation must first understand the changes in the following two types of steel forming processes. Rotate the side change handle 1, rotate the A1-3 wheel by 180°, (the fixed side A1-3 is unchanged), change the bending direction of the lower side of the operation side. Rotate the change handle 2 on the fixed side, rotate the A4 and 5 rollers 180°, (the change side remains unchanged), and change the final forming angle of the small side (90°→135°) 3、Leveling   Leveling is an important position to adjust the shape of the plate. After the formed plate comes out, if there is side bending, upturning, under arching, twisting, etc., it will be processed by the leveling part. Leveling has the following two integer changes: 1）The leveling part is composed of two sets of rollers and shafts. A set of rollers at the beading position acts as a positioning function, and a set of rolls at the punching and shearing position acts as a bending correction. The shafts are generally used to correct upturning, under arching, twisting. and so on. If it bends up, the adjusting screw drives the roller part to move down as a whole, on the contrary, if it bends down, it adjusts up. At the same time, the small leveling part also needs to move up and down synchronously with the big leveling part. 2）If the formed product bends upwards or downwards in the length direction, it needs to be solved by adjusting the leveling part of the forming machine. If it bends upwards, the adjustment screw drives the roller part to move down as a whole; Conversely, if it is bent down, adjust it up. At the same time, if the leveling effect is not good at the same time, it should be completed together with the guide roller.

Note: In the relative input mode, a column can only have one value, and the position of the input hole is relative to the distance from the previous hole, not the distance to the head end.
 

4.4 Set Interface

Click the setting bar to enter the parameter setting interface as shown in the figure below:
 
："Automatic speed" refers to the speed of the motor during automatic production, which is generally set arbitrarily between 0-600, and there is a upper limit speed according to the actual model. The user cannot set more than this value. Exceeding this value may damage the machine and affect its service life. The user can freely set the motor speed in the automatic production process according to the actual situation. For example, when producing thicker plates, the automatic speed should be appropriately reduced to prevent the motor from overloading and alarming. Similarly, when producing thin plates, the servo speed can be increased appropriately. In the process of automatic production, the automatic speed cannot be set. If the speed needs to be adjusted during automatic production, the machine needs to be paused first, and then the automatic speed can be adjusted.
："Manual speed" refers to the jog speed of the motor when the forward and reverse rotation is pressed in manual mode. The user can also freely set it between 0-600 according to the actual situation, and the use mechanism is the same as above.
：Allowable error range for length and hole position accuracy.
：The installation location of the printer.
：Can use the printer to print manufacturer information.
：Change the printer font size.
：Calculate the perimeter of the current length-counting encoder. The setting of the encoder perimeter determines the accuracy of the product length. At present, the default theoretical value of the encoder perimeter of our CZ machine is 400. However, if the encoder perimeter is set to the theoretical value of 400, the actual length of the product produced may not be accurate. So we need to adjust the encoder circumference according to the theoretical length and actual length of the product. Click “”, the system will pop up the encoder perimeter automatic calculation interface as shown below:
 
For example, when the circumference of the encoder is 400, a board of 3000 mm is produced, which is actually 1 mm longer, then input the theoretical length of the product as 3000, and the actual length of the product as 3001, and then click "Adjust", you can see that the encoder circumference value is automatically adjusted from 400 to 400.13. Regarding the encoder, it should be noted that since the external length measuring encoder is an important part of the fully closed-loop system, it is responsible for measuring the length of the product. Therefore, in the process of automatic production, it is necessary to ensure that the encoder is synchronized with the product, and the encoder roller must be pressed tightly without slipping, otherwise the length of the product will be inaccurate or even the motor will run off.
：Since there will be a certain length loss when rear cutting, this loss must be calculated in the program, so a cutter thickness must be set. If the setting is wrong or not set, the product length will be inaccurate. The thickness of the rear cutter of our machine is 8mm and 6mm respectively, and it is adjusted according to the actual thickness.
 
These two parameters only apply to the ordinary motor and hydraulic version. The initial braking distance acts on the deceleration in advance when the plate has not entered the forming section and is positioned to 10mm (adjustable parameters). After entering the forming section, use the brake distance to locate at 8.5mm (adjustable parameters) and then start to decelerate to ensure accuracy. The two parameters of the servo version do not work.
:The animation spacing is used to set the animation spacing of the main interface. If the animation spacing is not set properly, you may not be able to see the position of the rear cutter. The default is 150.

4.5Factory Settings

Click the factory setting to enter the parameter setting interface as shown below:
 
  ：The number of cylinders refers to the total number of machine cylinders, including punching cylinders and cutter cylinders. For example, if the machine has 6 punching holes plus a pre-shear and a post-shear, the number of cylinders should be set to 8. Note that in some cases, two side-by-side cylinders on machine that always punch simultaneously should be counted as one cylinder.
:Do you need a virtual keyboard when editing? If there is no external keyboard, you need to add a virtual keyboard. The default selection is yes, and the keyboard will automatically pop up when you edit (as shown below).
 
：The maximum number of holes supported by a single product can be adjusted, and the default is 50.
 
Number of cutters: It is used to select the number of cutters for the machine. If the device is a single rear cutter, select "single cutter", if the device is a front cutter plus a rear cutter, select "double cutters" to choose the front cutter or back cutter.
：The cutter stop mode is only applied to the cutter after using.
The stop mode of the front cutter is that when all the products are produced, the plate stops at the position of the pre-shear, and there are still uncut products in the machine, and then the front cutter is used to cut the plate manually, and the mechanical clutch is pulled up. Then manually remove the products that have not come out of the machine. It is necessary to manually measure the position of the cutter, and cut it after manual use.
The rear cutter stop means that when all the products are produced, the plate will pause at the position of the front cutter, and the customer can click to start again, and the machine will automatically cut the uncut part of the machine.
The difference between the two methods is that the stop of the front cutter saves more material and almost produces no waste, while the stop of the rear cutter will generate more waste.
 
If your machine is equipped with automatic changeover, select "automatic changeover" for the changeover type.
If your machine is equipped with manual changeover, select "manual changeover" for the changeover type.

Each piece: Stop reminder when each piece of product is completed.
：Set according to the actual selected PLC. For the time being, only Panasonic FP-XH series PLCs and PLC brands that support the standard Modbus protocol are supported.
 
The communication type can support RS232 serial port, and industrial Ethernet network port, and the serial port is selected by default.
  
The printer only supports Yida printer temporarily, the number of nozzles can be selected according to the actual number, and the printing content can be selected according to the required printing form.
：The power type is selected according to the actual situation. Servo motor is selected when servo is used, asynchronous motor is selected for ordinary motor, and oil pressure motor is selected for hydraulic motor.
 
Options: data source can be cloud transmission or local U disk import and on-site editing.
Cloud task: the data source can only be cloud transmission, and the networked machine only supports cloud transmission.
Local task: the data source can only be local U disk import and on-site editing.
：It is used to select the dry run mode, select off in the case of normal automatic production, only select to open in the dry run mode, the dry run mode is used for debugging machine, and generally customers do not need to use it. Note that the plates must be removed when the machine is running in dry mode.
 
The selection of the input method is the selection of the hole position editing method, which can be selected according to the customer's input habits. The detailed description has been explained in the editing data section, and will not be introduced here.
Cutter check only applies to the relative input mode. When it is enabled, the last cutter position of each batch of data edited by relative input mode does not need to be manually input, and the software automatically calculates it.

The factory default serial port communication settings are as follows:
 
The factory default network port communication settings are as follows:
 
Our company's factory machine defaults to serial port communication, and network port communication requires that the corresponding PLC has an industrial Ethernet interface.
4.7 Cylinder Setting
Click "Cylinder Setting" to enter the cylinder setting interface as shown below:
 
 
In order for the machine to make accurate products, various parameters must be set, and the position of the oil cylinder is one of the important parameters that affect the accuracy of the product. The cylinder position reflects the position information of each cylinder and feeds back to the system. The system will calculate when it needs to act according to the cylinder position. The position information of the oil cylinder is debugged and filled in by our company before the machine leaves the factory. Under normal circumstances, it does not need to be changed, but sometimes it needs to be fine-tuned according to the actual situation. If the position of the oil cylinder is accidentally set, you can let the material belt enter the machine in manual mode, manually punch down all the punching holes, and cut down with the cutter, and finally let the material belt come out and measure the center of each hole. For how to measure the hole position and fill in the program, the following is the specific method:
First of all, the position of No. 1 oil cylinder is the reference position, which can be set freely in theory (but cannot be set to 0), and we generally set it to 100 by default. When the No. 1 oil cylinder is set to 100, when the material belt stops at the center of the No. 1 oil cylinder and starts automatic production, the length of the waste material cut off by the first knife is 10 cm. The second thing to do is to measure the position of the other cylinders to the No. 1 cylinder. For example, the distance from the center of No. 2 to the center of No. 1 cylinder is 200, then the position of No. 2 cylinder is 200+100=300. That is: the position of No. N oil cylinder = the distance from No. N oil cylinder to No. 1 oil cylinder + the reference position of No. 1 oil cylinder.
Click "", (currently only supports the automatic adjustment of the rear cutter) can be used to automatically adjust the position information of the rear cutter, input the actual distance and theoretical distance from the first hole to the cutter (as shown in the figure below), click to adjust the cutter position, the program will automatically adjust the cutter position.
If the die has upper and lower limit sensors, the upper and lower limits do not need to set the delay time, the default is 0ms, if there is no corresponding sensor, you need to use the delay to simulate the original point of the limit sensor to limit the action time of the cylinder.
 

4.8 Cylinder Test

Click "Cylinder Test" to enter the cylinder test interface as shown below:
 
The oil cylinder test is a manual action oil cylinder, which is generally used for manual punching and cutting or checking whether the oil cylinder is normal. The origin and moving point of the window reflect the position of the die. The light green reflected by the sensor of the machine indicates that the oil cylinder has reached the current position, and the dark green indicates that the oil cylinder has not reached its current position.
Note: when operating this interface, please pay attention to whether the machine is safe.
 

4.9 Machine Change

Click "Machine Change" to enter the change interface as shown in the figure below:
 
：The status display of the type change. If the automatic type change is not started, it will be dark green, and it will show that the type change is preparing, and after clicking "Adjust", it will change to dark and light green alternately, and it will show that the system is changing type.
：Plate width display, the plate width can be calculated automatically after inputting the plate width thickness (current thickness), waist height (A current length), bottom width (B current length) and lip (C current length).
：Choose the type change method according to your needs, and temporarily support four types of change methods: C type, Z type, U type and “几” types.
：The plate thickness is based on the plate thickness selected when calibrating the benchmark, and will not be modified unless the benchmark is re-calibrated.
 
A corresponds to the height of the replacement type, B is the bottom width of the replacement type, and C is the lip.
 
Display the current position and target position of the corresponding motor, and you can jog to make the motor move forward and backward. You can see the positive and negative limit indicator lights of the corresponding motor. If the limit is not touched, it will be light green, and if it hits the limit, it will be dark green.
Changeover start and stop buttons
Click "Model Change Setting" to enter the parameter setting of the model change. When using the automatic model change function for the first time or when the automatic model change is inaccurate, it is necessary to perform a model change calibration. Calibration and change methods:
 

• Set the action mode of A1 and A2 lane change mode. Since different devices A1 and A2 operate in different ways (simultaneous, independent, and in the same direction), it is necessary to select "A1, A2 synchronous action" or "A1, A2 independent" or A1, A2 in the same direction. If you are not clear about the working method of machine A1 and A2, please contact us.
• Set the maximum size, click "Maximum Size Setting" under the model change interface, the maximum size of each model is inconsistent, fill in according to the actual model.

 

• Set the resolution of the changeover encoder. Unless it is a special model, the default resolution of our changeover encoder is 1000, no need to set.
• Set the reduction ratio of each transformation. The reduction ratio here refers to the distance that the encoder moves for one revolution, and the reduction ratio of each conversion may be different for different machine. For example, if the encoder rotates one circle, the type change of track B will advance 1mm, then the reduction ratio of track B should be set to 1. We will set the correct reduction ratio before leaving the factory. If you encounter unexpected situations such as data loss, please contact us.
• Set tolerance. The allowable deviation here refers to the deviation allowed for automatic type change, in millimeters. It is worth noting that the deviation here should not be set too small. If it is set too small, there may be a phenomenon that the type change motor cannot be positioned when it rotates back and forth. Generally, the factory default setting of the deviation here is 1.

 f.Set the current value of the encoder. It is necessary to set the current value of the encoder when the machine is not debugged or when the automatic type change needs to be re-calibrated. The following is the specific methods.
  f1.Manually adjust the machine to change the type (C type, any specification), and the height on both sides and the width of the lip of the board shape required to be made are basically the same.
  f2.Let the machine produce a product, measure and record the bottom width, height, and lip of the product (if the scale of the machine has been calibrated, you can directly read the relevant parameters from the scale).
  f3.Fill in the measured A height, B bottom width, and C lip into the corresponding size column (as shown in the figure below).
 
After filling in all, the software will automatically calculate the target position of each type-changing motor, and the next thing to do is to set the current position parameter of the type-changing motor to be the same as the target position parameter.
f4.Click "Model Change Setting" under the model change interface, as shown in the figure below, the target position has been calculated by the program at this time, what needs to be done is to fill in the "Target Position" in the blank column of "Encoder Setting Value", and click “setting”.
 
Use of automatic changeover：
After the changeover calibration is set in the previous step, you can directly select the type of changeover on the main changeover interface, fill in the specification data to be made (bottom width, height, lip), and the program will automatically calculate the target position of each motor, click "Adjustment", the device will start automatic changeover, when it reaches the target position within the error range, the changeover will automatically stop.

Punching and shearing operation instructions

1. Pre-production Inspection

Trial punching and cutting in the state of no material, check whether the falling and lifting positions of the punch are normal, check whether the moving parts of the limit switch are loose, check whether there is interference in the circuit and oil circuit.

1. Trial Punching

Use a piece of leftover material (thickest board thickness required) to try punching. If there is any abnormality, please check the pressure. Use a small round rod with a diameter of less than 5 to withstand the coil end of the relief valve, and observe the highest value of the pressure gauge. Generally, it should be 1 0-12Kg/cm2. If the pressure is not reached, please adjust it by adjusting the pressure regulating valve superimposed on the overflow valve. When adjusting, turn the handle to observe the pressure change until it reaches the normal value. Before entering the punching die, adjust the punching die position. Drive slowly into the die to see if there is any interference.

1. Trial Shearing

Run the scissors on the upper and lower empty plates, check whether the moving parts of the travel switch are loose, whether there is interference in the circuit and oil circuit. Slowly drive into the knife edge, if there is any interference, adjust the position of the knife edge in time, after passing through the knife edge smoothly, observe the gap between the plate and the knife edge, generally about 1-2mm, open about 100mm and try to cut. Observe whether the incision is smooth or not, and if necessary, adjust the gap between the knife edges and try cutting again until it is smooth and free of burrs. The manual plate passes through the knife again, and observes whether the plate collides with the knife. If necessary, adjust the front knife group and the rear knife group dislocation gap.

1. Production

After the above steps are correct, the production shall be carried out referring to the manual of the electrical part. The first sample produced shall be measured for the first piece, and mass production can only be started after confirming that it is correct. (It is necessary to observe whether there is any abnormality in the moving parts of the whole machine during the production process, and measure whether the effective length of the product is qualified from time to time.)

6.3 Daily Maintenance

1. Please provide reliable grounding, the PLC ground and the motor ground are separated and should be set separately.
2. Please check whether the voltage is stable, the required voltage range (three-phase 380 V +5%), if it exceeds the range or the power grid is unstable, please provide an online 40KVA regulated power supply.
3. The encoder, photoelectric switch and other control lines should be separated from the power line as much as possible to avoid interference. The motor, solenoid valve, and main power supply enter the line from the inverter end, and the encoder, photoelectric switch, etc. enter the line from the other end of the control cabinet.
4. The control cabinet must not be placed in direct sunlight. Working temperature 0~40 ⁰C , altitude below 1000 meters.
5. Non-professionals should not adjust the device inside the cabinet.
6. If the machine is damaged due to the above reasons, the cost shall be borne by the customer.
7. Subsequent design cabinet wiring is subject to change without prior notice.

6.4 Daily Inspection and Maintenance

1. Strictly implement the lubrication five-set standard and the point inspection and patrol inspection system. Keep the appearance of the machine clean and tidy, without running, popping, dripping, or leaking.
2. Machine maintenance personnel need to be familiar with the working principle and operating procedures of the system.
3. Check the operation of hydraulic components, pipelines, working cylinders and travel switches in the system at any time to ensure flexible operation, reliable action, and good sealing. If abnormal conditions such as noise, oil leakage, and inflexible rotation are found, stop the machine immediately.
4. Regularly clean pipelines, fuel tanks and components, etc., and deal with leakage points in time. External cleaning, once a month, so that leaks and hidden troubles can be easily found.
5. Regularly conduct physical and chemical analysis of hydraulic oil, and filter and change oil in time according to the oil quality standard. The hydraulic oil entering the oil tank must be filtered by the oil filter machine every time. It is recommended to clean the oil filter screen every six months.
6. Set up and adjust each component in time according to the requirements of use to ensure the stability of the pressure in the system and eliminate vibration and slow movement.
7. All detection and control components that have been repaired and dismantled must be readjusted according to the original setting before use.8、Frequently check whether the fastening screws of the joints and valve body are loose or leaking oil. When leakage is found, it should be tightened in time, and the corresponding accessories should be replaced if necessary.
   9、Check the air filter once a month, and the inspection cycle can be determined      according to changes in environmental conditions.
   10、Hydraulic system with air cooler: the cooling fins must be cleaned about every 2-3 months and whether maintenance is required.
