Description

Technical Field

[0001] The utility model belongs to the field of mechanical engineering, and particularly relates to an adjustable process support rod. Background Art

[0002] Aluminum alloy subway car bodies have the advantages of light weight, corrosion resistance, high appearance flatness, and easy to manufacture complex and beautiful curved car bodies, so they are welcomed by urban transportation and railway transportation departments around the world. Aluminum alloy car bodies have occupied a major position in the aluminum alloy urban rail and railway transportation vehicles that have been put into operation. Some developing countries are also vigorously developing aluminum alloy car bodies and have the ability to mass produce them. Since aluminum alloy car bodies will produce certain welding deformation after assembly welding, the welding direction is mainly the lateral shrinkage of the weld. How to use the weld shrinkage stress to offset each other is the basis for formulating the welding sequence. At the same time, increasing the anti-deformation force in the deformation direction to solve the deformation is an effective way to control the deformation of aluminum alloy. There are many places in the subway production that involve the assembly and welding of wide and large profiles. Before welding many wide and large profiles, convenient and easy-to-disassemble anti-deformation struts are required to control the deformation. Utility Model Content
