How to avoid electric shock and precautions for assembly and welding of tile press

Under the action of welding stress, if the restraint of the weldment is small, such as the thickness of the plate is thin or in a free and unrestrained state, the weldment will produce corresponding dimensional changes or shortening, bending or warping. If the restraint degree of the weldment is very large, such as the plate thickness is large, the shape is complex, or the weldment is in a strong restraint state due to the artificially imposed fixture, at this time, the weldment cannot deform freely, but local strain will be generated under the action of welding stress, and large residual stress will be generated at the same time. The peak value of residual stress in the weld zone can reach the yield strength of the material. Therefore, the magnitude of welding internal stress is related to the thermal expansion coefficient of steel and the restraint degree of joint. The expansion coefficient of structural steel changes little, while the restraint is related to various factors, such as the form of structural joints, welding sequence, plate thickness, and the fastening degree of external fixtures

if it is expected to expand or fix other components in the future, the foundation should be segmented, and the connecting end of the foundation should be installed with additional plates and connectors. The foundation of the double-layer color steel tile press and the longer color steel tile equipment should be divided into two or more parts to facilitate processing, handling (lifting) and transportation. If it is expected to expand or fix other components in the future, the foundation should be segmented, and the connecting end of the foundation should be installed with additional plates and connectors. The foundation of color steel tile equipment should be able to realize the recirculation of lubricant used in cold bending. When separating the foundation, pay attention to the recirculation lubrication of each foundation or the watertight connection between foundations
