A flanging die for eliminating the surface undulation of the fuel tank port of the side wall outer plate

Abstract

The invention relates to a flanging die for eliminating the undulation of the surface of the fuel tank port of the side wall outer plate, which comprises a fuel tank port pressing profile, a die lower die convex model surface and a lower model surface adjusting block, and the lower model surface adjusting block is fixed on the die lower die On the mounting base of the lower model surface adjustment block of the convex model surface, an open profile surface is set on it, which is convenient for adding padding to reduce the trimming workload when adjusting the height of the profile surface, and at the same time avoids the work of the open profile surface being higher than the lower model surface adjustment block. It affects the effective support of the surface of the fuel tank mouth. After the fuel tank mouth is punched, the side wall outer plate process part with the increased length of the trimming contour line is put into the flanging die, and the stamping part automatically falls into the lower die convex model surface of the flanging die. In the theoretical position, the upper and lower molds are clamped on the flanging die to effectively control the material in the non-deformed area of ​​the flanging ridgeline area of ​​the fuel tank port. The invention not only helps to reduce the workload of debugging and modification, but also avoids unqualified mold profile data caused by repair welding modification, and solves the problem of surface fluctuation of the fuel tank port of the side wall outer plate.

Description

technical field [0001] The invention belongs to the technical field of stamping, in particular to a stamping die that does not require repair welding adjustment and can adjust the profile height, in particular to a flanging die that eliminates the surface undulations of a side wall outer plate fuel tank port. Background technique [0002] In the process of automobile stamping production, the problem of the surface undulation of the fuel tank port of the side panel outer plate is a process defect, which is a common problem, and the serious surface undulation of the fuel tank port is an unacceptable defect. [0003] In the prior art, after the process piece completed by punching the fuel tank port of the side wall outer plate is put into the flanging die, the stamping part automatically falls into the theoretical position of the convex model surface of the lower die of the flanging die, and the width of the fuel tank port flanging pressing material is the same as that of the fl...
