Continuous stamping die for end cover bottom plate of automobile heater motor

Abstract

The invention relates to a stamping die, in particular to a continuous stamping die for a bottom plate of an automobile heating motor end cover. The continuous stamping die comprises an upper die part, a lower die part and an air cylinder forming part, wherein the air cylinder forming part comprises a tearing terrace die, a forming terrace die, a spring, a flanging-sizing terrace die, a piercing die, a plunging die and a blanking die, which are sequentially arranged on the upper die part, as well as a flanging-sizing cavity die which is arranged on the lower die part. Compared with the prior art, the continuous stamping die has the advantages that the die structure and the process are improved, so that a plurality of pairs of conventional single dies are integrated onto one pair of dies, and therefore, production efficiency and product quality are greatly improved; and dual floating blocks are adopted to guide and feed, so that too heavy products carried unilaterally are fed smoothly inside the die.

Description

technical field [0001] The invention relates to a stamping die, in particular to a continuous stamping die for the end cover bottom plate of an automobile heater motor. Background technique [0002] Stamping die is a process equipment for processing materials into parts in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] In each stroke of the press slider, only the same punching process can be completed, which is called a single-process die. The single-process die is divided into: blanking die, punching die and trimming die. [0004] The shape and structure of the bottom plate of the end cover of the automobile heater motor are complex, and the mold structure for producing the bottom plate is also very complicated. In the pr...

AI Technical Summary

Problems solved by technology

[0004] The shape and structure of the bottom plate of the end cover of the automobile heater motor are complex, and the mold structure for producing the bottom plate is also very complicated. In the prior art, a single-process mold is usually used for production. The production of a single-process mold is time-consuming, laborious and very costly, and cannot be mass-produced. The goal

The existing single-process mold has the following problems: (1) multi-process, multi-machine, multi-labor, multi-energy consumption, high production cost; (2) multi-process production mode is difficult to achieve comprehensive management in terms of quality and production management, It is also very difficult in quality control. The previous processes have been produced. If there are quality problems in the subsequent processes, all products and process parts will face the risk of being completely scrapped.
