Progressive die and feeding device thereof

Abstract

The invention discloses a progressive die and a feeding device thereof, relates to progressive dies, and aims to provide a feeding device of a progressive die. The feeding device has the advantage ofreducing material strip abrasion when a material strip is conveyed. According to the technical scheme, the feeding device of the progressive die comprises a moving groove formed between all groove bodies of a lower die, a moving block which is slidably connected into the moving groove in the vertical direction, a plurality of first compression springs arranged between the moving block and the bottom of the moving groove, and ejector rods which are arranged on an upper die and correspond to the moving block; when the first compression springs are in the original state, the upper end of the moving block stretches out of the moving groove, the material strip at the upper end of the moving block is located at the upper ends of the groove bodies; and when the upper die is separated from the lower die, a first driving piece for driving the material strip to move in one direction is arranged in the moving block.

Description

technical field [0001] The invention relates to a continuous mold, in particular to a continuous mold and a feeding device thereof. Background technique [0002] Continuous die refers to the cold stamping die that uses strip-shaped stamping raw materials in one stamping stroke, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. Move once with a fixed distance until the finished product is completed. Existing molds for processing car seat slide rail brackets generally consist of a plurality of punches and a plurality of dies. [0003] Notification number is that the Chinese patent of CN203526341U discloses a kind of continuous mold that is used for processing the car seat slideway wall plate, and it comprises lower mold, upper mold, punching and pressing mold, bending mold, punching mold, shearing mold And forming mold, and lower bearing plate, lower mold pad, lower mold base, lower mold backing plate, lower mold...

AI Technical Summary

Problems solved by technology

[0004] However, after the material strip is processed at a certain station, it needs to be transported to the next station through the feeder. The feeder only generates thrust on one end of the material strip, so that the material strip is easy to communicate with when it is transmitted between various stations. The individual dies on the lower die are worn
