The colour steel roll forming machine welding work and other Preparation work
Tile press assembled at the welding stress, if the binding of color-coated steel weldment smaller devices, such as thin thickness in a free or unconstrained state, the weldment will produce a corresponding change in the size or shortened or bent or warped music and so on. If the binding of large weldments, such as the thickness of the larger, complex shape or because of human c-beam equipment for the jig is applied and under the strong binding state, when the weldment can not be freely deformed, but stress in welding It will produce local strain while producing greater residual stress. Peak residual stress weld zone can reach the yield strength values of the material.
Therefore, welding stress their size and coefficient of thermal expansion of steel concerning joint restraint. Coefficient of expansion of steel structure changed little, while the binding of the form and structure of nodes, welding sequence, thickness, plus various factors such as the degree of tightening fixture related.
Before color steel tile press used to check the connection is solid throughout, mounting bolts, whether or tighten the nut, right and left inner chassis lubrication should add a little oil to power-up color steel tile press machine test, first empty running carefully observed , with or without vibration, noise, oil window is to oil, whether coordinated motion components before you can install all the normal mold, mold installation, must be cut off, by hand moving belt or gear motor, so indexing table, and carriage rise to the highest point, it is best to use an object supported between the table and the bottom surface of the slide to slip seat natural fall, causing the accident. Caigang pressure tile machine features: The device has a steel tile operation, maintenance, mechanical maintenance and debugging, easy mold replacement, etc; the entire unit automation control system us
