Abstract

The invention discloses a trimming and flanging composite stamping die used for finishing one-step stamping for trimming and flanging processing of a workpiece. The trimming and flanging composite stamping die comprises a combination segmental blade, a pressing mechanism, a supporting mechanism, an upper die base and a lower die base and is characterized in that a trimming die and a flanging die which share the same pressing mechanism and supporting mechanism are combined together; the whole die is of a bilaterally-symmetric structure; trimming segmental blades are distributed at two sides of the die; and the pressing mechanism and the supporting mechanism are arranged between the upper die base and the lower die base. According to the invention, workpiece trimming and flanging operations are independently finished by using one die, accumulation of die locating deviation and workpiece processing errors caused by two processes in the past is avoided, the repeated installing and debugging steps in the original processing method are reduced, the production cost is greatly reduced, the production efficiency is remarkably increased, and meanwhile, the consistency of products is also ensured.

Description

technical field [0001] The invention relates to a compound stamping die, which is especially suitable for a stamping die combining workpiece trimming and flanging, and belongs to the technical field of metal stamping. Background technique [0002] Die stamping of automobile body panels is the front-end process of body parts production. Its processing accuracy has an important impact on the quality of vehicle assembly. High-quality stamped and formed panels are a necessary condition to ensure smooth vehicle shape and product consistency. At present, the stamping process of automobile panels is: drawing, trimming, flanging and shaping, punching and side punching. Each process needs to be completed by an independent set of molds and punching machines. Not only does it have high investment costs for molds and machine tools, but also The disadvantages of cumbersome installation and debugging, low work efficiency, and the workpiece needs to be processed by multiple processes, ...
