CN-122007274-A - Stamping die for automobile parts

Abstract

The invention relates to the technical field of stamping dies and discloses a stamping die for automobile parts, which comprises a lower die and an upper die, wherein a base plate convex part is arranged on the lower die, a sealing plate convex part is arranged on the base plate convex part, a base plate groove matched with the base plate convex part and a sealing plate groove matched with the sealing plate convex part are formed in the bottom of the upper die, when a workpiece is placed on the lower die, the upper die moves downwards to stamp the workpiece, and a corresponding base plate structure and a corresponding sealing plate structure can be stamped on the workpiece through the base plate convex part and the sealing plate convex part on the lower die. According to the invention, the sealing plate protruding parts are integrally arranged on the backing plate protruding parts of the lower die, so that the forming and the function opening blanking of the backing plate main body are synchronously completed in the same set of die, and the opening surplus materials originally used as waste materials are directly formed into the useful trunk sealing plate, thereby improving the material utilization rate and reducing the input cost and the process circulation time of the special sealing plate die.

Description

Stamping die for automobile parts Technical Field The invention relates to the technical field of stamping dies, in particular to a stamping die for automobile parts. Background Trunk floor boards (also called trunk bottom boards, trunk floors or spare tire cover boards) are important functional parts in modern automobile interior trim systems, are usually installed at the bottom of a trunk (trunk) of a vehicle, cover above a spare tire groove or a storage space, play a comprehensive role in carrying luggage, isolating noise, beautifying the interior trim and protecting the storage space below, and need to be formed by stamping a plate by using a stamping die when the floor boards are processed; In the structure of the trunk of the automobile, the trunk sealing plate is used as an independent small ornament arranged on the inner side of the back door and generally plays roles of covering an internal sheet metal structure, arranging an overhaul window and improving the integral visual consistency of the luggage compartment, and compared with a ground cushion plate paved at the bottom of the trunk and having larger area, the sealing plate belongs to an auxiliary covering piece with relatively regular shape and smaller size, but also has good rigidity, assembly precision and matching performance with the peripheral interior ornament, so that the trunk sealing plate needs to be punched by a special punching die; In the production process of the trunk ground backing plate, in order to realize local avoidance or function opening of a part area, such as an opening structure for installing anchor points, handles or facilitating taking and placing of a bottom storage groove, a blanking process is usually required to be designed in a die to form a corresponding opening, however, in the conventional process, the plate surplus material punched out of the opening area is usually directly treated as waste, effective recycling of materials is not realized, meanwhile, the trunk sealing plate is used as another independent component, and a special die is required to punch the trunk sealing plate in the processing process, however, in the prior art, a structure design is lacking, which can complete forming of the trunk ground backing plate main structure and blanking of the function opening in the same set of stamping die, and synchronously directly form the plate punched out of the opening area into the trunk sealing plate. In order to solve the problems, the application provides a stamping die for automobile parts. Disclosure of Invention The invention provides a stamping die for automobile parts, which solves the problems of scattered working procedures and increased cost caused by the fact that the spare materials generated by blanking of functional openings of a trunk ground backing plate are directly abandoned, the material utilization rate is low, the trunk sealing plate is required to be processed by an independent die, and the integrated die design for directly forming the spare materials of the ground backing plate into the sealing plate is lacking. The invention provides a stamping die for automobile parts, which comprises a lower die and an upper die; the lower die is provided with a backing plate convex part, and the backing plate convex part is provided with a sealing plate convex part; a backing plate groove matched with the backing plate convex part is formed in the bottom of the upper die, and a sealing plate groove matched with the sealing plate convex part is formed in the bottom of the upper die; When a workpiece is placed on the lower die, the upper die moves downwards to punch the workpiece, and the corresponding backing plate structure and the corresponding sealing plate structure can be punched on the workpiece through the backing plate protruding piece and the sealing plate protruding piece on the lower die. As a further optimization scheme of the invention, the backing plate convex piece comprises a backing plate bulge, the backing plate bulge is arranged at the top of the lower die, and the backing plate bulge is integrally formed with a special-shaped bulge. As a further optimization scheme of the invention, the sealing plate protruding piece comprises a sealing plate protrusion, the top surface of the backing plate protrusion is integrally formed with a sealing plate protrusion, and the sealing plate protrusion is integrally formed with a cross protrusion.
