Stamping multi-station die for medium-sized automobile parts and its operation method

Abstract

The invention provides a stamping multi-station die of an automobile middle-sized part and an operation method of the stamping multi-station die. The stamping multi-station die of the automobile middle-sized part comprises an upper die and a lower die. The upper die comprises an upper die seat, and the lower die comprises a lower die seat. The upper die seat and the lower die seat are provided with trimming stations, punching stations and shaping stations. The trimming stations comprise trimming positioning structures and trimming tools. The punching stations comprise punching positioning structures and puncher pins. The shaping stations comprise shaping positioning structures and shaping tools. The trimming stations and the punching stations are located on the two sides of the shaping stations. According to the stamping multi-station die of the automobile middle-sized part, the overall tonnage of a single stamping part die is reduced, the investment of cost of the die is saved, and the requirement for storing space of the die is lowered.

Description

technical field [0001] The invention relates to the field of stamping and forming, in particular to a stamping multi-station die for medium-sized parts of automobiles. Background technique [0002] Automobile body-in-white parts are mostly stamping parts. After the structural design of the stamping parts is determined, the economy of its processing should be fully considered to minimize the cost of stamping parts. The cost of stamping parts usually includes blank sheet cost, stamping cost, mold tooling amortization cost, etc. In most factories, external conditions such as equipment, personnel, and materials are basically unchanged for a certain period of time, but to reduce the cost of stamping parts, it is mainly from the rational arrangement of the stamping process. [0003] Taking automobiles as an example, the length of stamping parts for automobile body-in-white is generally within 3 meters, and the length of parts with more than 60% (weight) of body-in-white is mainly...

AI Technical Summary

Problems solved by technology

For medium-sized parts, according to the above-mentioned traditional layout, it often occurs that larger machine tools produce smaller molds, resulting in the invisible waste of the so-called "big horse-drawn cart"

At the same time, it has also caused the bottleneck of resource shortage of medium-sized stamping machine tools of various stamping manufacturers, the waste of the overall tonnage of model molds, and the waste of stamping costs of overall stamping parts of models.
