Problems solved by technology

However, when the strip is particularly thin, its strength is insufficient, and there is a certain distance between the feeder and the mold, the strip between the feeder and the mold will sag and deform, and the feeder cannot smoothly send the strip to the mold, let alone Make the material belt move forward according to a fixed step distance, which seriously affects the stamping efficiency and quality

Abstract

A material pulling structure of a continuous progressive die comprises a material belt, a lower die body and an upper die body, and is characterized in that guide edges on the two sides of the material belt are provided with material pulling holes; a lower die base is provided with a buoyancy lift block; a conveying channel is formed in the part, corresponding to the material belt, of the buoyancy lift block; the buoyancy lift block is provided with a limiting step, and the limiting steps corresponds to a material pulling pin; the vertical distance between the upper surface of the limiting step and the conveying channel is matched with the step pitch of the continuous progressive die; an upper disengagement plate is connected with an upper die base through a third spring; the upper die base is provided with the material pulling pin, and the material pulling pin is connected with the upper die base through a second spring and located in front of a lower die plate; an avoiding groove is formed in the part, corresponding to the upper portion of the buoyancy lift block, of the upper disengagement plate; in the conveying direction of the material belt, the buoyancy lift block is located between the lower die plate and the material pulling pin; and the elastic force of the third spring is larger than that of first springs, and the elastic force of the first springs is larger than that of the second spring.

Description

technical field [0001] The invention relates to the stamping field, in particular to a drawing structure of a continuous progressive die. Background technique [0002] The continuous progressive die is composed of multiple stations, and each station is connected in sequence to complete different processes, and a series of different stamping processes are completed in one stroke of the punching machine. After a stroke is completed, the punch feeder moves the material belt forward according to a fixed step, so that multiple processes can be completed on a pair of molds. However, when the strip is particularly thin, its strength is insufficient, and there is a certain distance between the feeder and the mold, the strip between the feeder and the mold will sag and deform, and the feeder cannot smoothly send the strip to the mold, let alone The material belt is moved forward according to a fixed step distance, which seriously affects the stamping efficiency and quality. Conten...
