Elastic discharging device in high-speed precise punching die for automobile terminals

Abstract

The invention discloses an elastic discharging device in a high-speed precise punching die for automobile terminals. The elastic discharging device comprises an upper die and a male die fixing plate, an elastic discharging block is arranged on the upper die, a blanking male die is arranged on the male die fixing plate and comprises a first working end face and a second working end face, a large waste discharging hole is formed in the first working end face, and a small waste discharging hole is formed in the second working end face. The elastic discharging block is matched with the first working end face, and connected with the upper die via a screw plug which is arranged on the upper die and penetrates an elastic part. Compared with the prior art, the elastic discharging device has the advantages that the requirements on part production of the two waste discharging holes of different models are met by one discharging block, and the device is simple in structure and convenient to use; production number of the elastic discharging block is reduced effectively, so that production cost is lowered; working procedures are decreased, time and labor are saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a discharge device of a stamping die, in particular to an elastic discharge device in a high-speed precision stamping die of an automobile terminal. Background technique [0002] With the rapid development of the automobile industry and IT industry, automotive terminals not only require high appearance and small volume requirements, but also improve the quality of the terminals. Therefore, there are many technical difficulties and structural design requirements for stamping dies. Automotive terminals are small precision stamping parts, that is, the terminal products have high requirements for dimensional accuracy and positioning. The terminal materials use brass or phosphor bronze, which have good stamping performance and forming stability. It is formed through multiple processes such as high-speed precision stamping die punching, blanking, embossing, continuous bending, and shaping. Therefore, reasonable molding sequence, sta...
