The invention provides a pneumatic drive positioning structure for rear cross beam floor trimming. The pneumatic drive positioning structure comprises a rear cross beam floor trimming punching lowerdie base, a rear cross beam floor and a straight edge structure; and two pneumatic drive positioning mechanisms are arranged on the rear side of adjacent rear cross beam floor trimming and punching lower die plates on the rear cross beam floor trimming punching lower die base in a left-right symmetrical manner. According to the pneumatic drive positioning structure, the two pneumatic drive positioning mechanisms are arranged on the the rear side of adjacent rear cross beam floor trimming and punching lower die plates on the rear cross beam floor trimming punching lower die base in a left-rightsymmetrical manner, and therefore rear cross beam floor can be pushed into place through the two pneumatic drive positioning mechanisms during the stamping operation; and in this way, the use of stamping plates is reduced, and the cost of purchasing the plates in the early stage is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of stamping dies for auto parts, and more specifically relates to a pneumatically driven positioning structure for rear beam floor trimming. Background technique [0002] The rear crossbeam of the automobile floor is a sheet metal part formed by cold working, with multiple connection holes and complex edge contours. In the prior art, the production of the rear crossbeam of the front floor is usually based on sheet metal as raw material through drawing, cutting Edge, punching and other processing processes to complete. [0003] The mold currently used for punching the rear beam of the automobile floor is as attached Figure 7-8 Middle and rear beam floor trimming and punching lower die base 1, rear beam floor trimming and punching lower template 101, trimming insert 2, rear beam floor trimming and punching upper die base 3, rear beam floor trimming and punching upper As shown in the template 301, the mold pr...
