Drawing and trimming die

Abstract

The invention discloses a drawing and trimming die which comprises a lower die body (1), an upper die body (2), an upper trimming cutter block (12) and a lower trimming cutter block (11). An inclined wedge sliding block (5) is connected with the inside of the upper die body (2), a driving block (3) is arranged on the lower die body (1), and the driving block (3) is provided with two inclined faces. The upper die body (2) moves downwards to drive the inclined wedge sliding block (5) to attach to the two inclined faces of the driving block (3) and slide. An upper trimming cutter block (12) is arranged at one end of the inclined wedge sliding block (5), and the upper trimming cutter block and the inclined wedge sliding block (5) move in a synchronous mode. According to the drawing and trimming die, the working principle is simple, the layout of the parts is compact and reasonable, and the space of the die is not increased. Meanwhile, the inclined wedge sliding block moves stably and smoothly, trimming burrs are avoided, the quality of plate products is ensured, and the service life of the die is prolonged.

Description

technical field [0001] The invention belongs to the technical field of stamping and blanking dies for automobile cover parts, and more specifically relates to a drawing and repairing die with anti-distortion function. Background technique [0002] In recent years, with the continuous development of the manufacturing industry, the pursuit of product quality and the saving of manufacturing costs have become two major concerns of enterprises. At present, under the environment of increasingly fierce automobile competition and gradually compressed profits, the cost of mold development, which is the mother of the automobile industry, has gradually attracted the attention of OEMs, hoping to develop high-quality molds at a lower cost while meeting high-efficiency requirements. Production. While controlling the cost of the mold, a stable and reliable wedge with various functions is a necessary condition to ensure the realization of the reduction sequence. Especially complex panels ...

AI Technical Summary

Problems solved by technology

Due to the needs of its own structure and the satisfaction of the functions of the mold itself, the existing drawing and trimming die has a relatively long size, and the torque formed by the driving force, the return force of the return spring and the working force makes it difficult to achieve stability when the wedge is working. The working state of the stamping parts produces burrs, which affects the product quality and the life of the mold is also affected
