Car bumper accessory progressive die

Abstract

The invention discloses a car bumper accessory progressive die. The progressive die includes an upper die body fixing plate used for fixing an upper die body, a material pressing plate and a lower diebody fixing plate used for fixing a lower die body, wherein the upper die body fixing plate, the material pressing plate and the lower die body fixing plate are arranged from top to bottom. Accordingto a machining procedure, the upper die body sequentially includes a concave mold used for machining C-shaped reinforcing ribs, a flanging forming mold and a macroporous stamping mold. The concave mold is positioned in the middle of the lower surface of the upper die body fixing plate, the macroporous stamping mold is positioned on one side of the upper die body fixing plate, and the flanging forming mold is positioned between the concave mold and the macroporous stamping mold; the material pressing plate is movably connected with the upper die body fixing plate and provided with through holes which correspond to the concave mold, the flanging forming mold and the macroporous stamping mold and are used for being penetrated by the concave mold, the flanging forming mold and the macroporousstamping mold. The lower die body includes a convex mold used for machining the C-shaped reinforcing ribs, a flanging forming convex mold and a macroporous discharge mold which are matched with the upper die body for use. According to the progressive die, multiple work procedures are combined, the space can be saved, the production time is shortened, the production efficiency is improved, and thestamping precision is improved.

Description

technical field [0001] The invention relates to the field of automobile processing, in particular to a progressive die for automobile bumper accessories. Background technique [0002] An accessory in a car bumper such as figure 1 As shown, it mainly supports and strengthens the bumper. In the production process, it is necessary to cut a whole steel plate into the required shape, and then punch out C-shaped ribs on the steel plate, and also need to perform 90° flanging of the steel plate and punch holes in the middle of the C-shaped ribs. If it is carried out one by one, it is time-consuming during the transfer process, and each process needs to be positioned, which increases the chance of defective products, and may cause injury to the operator in the flanging process. Contents of the invention [0003] In view of the above problems, the present invention provides a progressive die for automobile bumper parts. This progressive die integrates multiple processes, which can...
