以前我公司在支架制造过程中,由于焊接变形控制得不好,容易造成整体组装困难。而该液压支架由于顶梁长度尺寸更大,截面厚度更小,并且护帮板结构也比以前各型号支架的复杂,焊缝密布,焊角高。因此其焊接变形也会更大,为此重点解决这两种结构件焊接变形问题,是保证此批支架的制造 In the past, my company in the stent manufacturing process, due to welding deformation control is not good, easy to cause the overall assembly difficulties. The hydraulic support due to the greater length and size of the roof beam, the cross-section thickness is smaller, and the structure of the support plate than the previous models of the complex stent, welding dense, high welding angle. So the welding deformation will be greater, to focus on solving these two structural deformation welding problems is to ensure the manufacture of this batch of stent
