Description

Technical Field

[0001] The utility model relates to the technical field of automobile covering parts, in particular to a flanging die for automobile covering parts. Background Art

[0002] Automobile covering parts refer to the surface or internal parts with spatial shapes made of metal sheets that cover the engine, chassis, cab and body. According to the function and location, they can be divided into three categories: external covering parts, internal covering parts and frame covering parts. They have different characteristics from general stamping parts in terms of process design, mold processing, equipment selection and quality control (dimensional tolerance, shape accuracy, part rigidity, surface quality) etc.

[0003] When flanging an automobile cover, it is necessary to place a blank on the lower mold, and use a power mechanism to drive the upper mold down into the lower mold to achieve flanging of the automobile cover. However, if covers of different sizes need to be processed, different molds need to be replaced, and the upper mold and the lower mold are usually connected in the machine by bolts. The replacement process is relatively cumbersome, which reduces the production efficiency of automobile covers. Utility Model Content
