Background

Automobile stamping parts, as the name implies, are metal stamping parts that constitute automobile parts. In the automobile stamping part, one part of the automobile stamping part is directly formed into automobile parts after stamping, and the other part of the automobile stamping part is formed into the automobile parts after being processed by welding, machining, painting or other processes after stamping. The automobile stamping parts are various in variety, and for example, the automobile shock absorber stamping parts comprise spring trays, spring seats, spring brackets, end covers, sealing covers, compression valve sleeves, oil seal seats, bottom covers, dust covers, impellers, oil cylinders, support lugs, supports and the like. A large amount of cold stamping processes are adopted in the production of automobile stamping parts, so that the requirement of industrial multi-variety and mass production of the automobile stamping parts is met. In medium and heavy-duty automobiles, most of the covering parts such as automobile body panels and the like, and some of the load-bearing and supporting parts such as automobile parts such as frames, compartments and the like are automobile stamping parts. The steel used for cold stamping is mainly steel plates and steel strips, the consumption of the steel of the whole automobile accounts for 72.6%, the cold stamping material has a close relationship with the production of automobile stamping parts, the quality of the material not only determines the performance of the product, but also directly influences the process design of the automobile stamping part process and influences the quality, the cost, the service life and the production organization of the product, so that the reasonable selection of the material is an important and complex work.

In the manufacture of automotive parts, it is often necessary to separate two already joined, very strong mechanical parts for purposes of inspection, disassembly, assembly, and the like. The currently widely used method for separating mechanical parts is as follows: and manually chiseling the hole with a hammer or other tools. When the operation is specifically implemented, the manual operation is used, so that the acting force is limited, time and labor are wasted, certain potential safety hazards exist, and the deformation and the breakage of machinery are easily caused. Therefore, a novel detection expanding tool which is simple and efficient to operate and has high action force is urgently needed.
