Problems solved by technology

[0002]In the prior art, the composite blanking die added on the progressive die generally has a structure of upper die, lower die, and a punch It is composed of a die, so that it is impossible to realize the punching work when it is necessary to punch more complex and large-volume products. Therefore, it is generally used to punch the holes in one-step mold, and then transfer it to another mold. Punching and blanking, such working methods lead to low manufacturing accuracy of the product, and large errors are prone to occur when re-aligning the benchmark, which greatly reduces the yield and work efficiency, so it cannot meet the requirements of manufacturing products

Abstract

The invention discloses a progressive die. A porous punching dire and a compound punching die are fixed on a lower die seat base plate, wherein a concave groove is formed in the top of an upper die seat of the compound punching die; a push plate is arranged in the concave groove; a force transmission rod is fixed on the bottom surface of the push plate; a concave part of a blanking concave die fixing plate is correspondingly matched with a through hole of a blanking concave die to form a die cavity; a beating plate is arranged in the die cavity; the bottom of the force transmission rod is fixed with the beating plate; an inner hole convex die fixing plate is fixed on the bottom surface of the upper die seat; an inner hole convex die is arranged in a die hole of the beating plate; after theinner hole convex die penetrates through the blanking concave die fixing plate, the inner hole convex die is fixed with the inner hole convex die; an unloading plate is internally provided with a blanking convex die; an inner hole concave die is formed in the blanking convex die; a die hole of the inner hole concave die is correspondingly matched with the inner hole convex die and a die hole of alower die seat; a discharging hole is formed in the lower die seat base plate; a spring I is arranged between the unloading plate and the lower die seat. According to the structure of the progressivedie, punching work can be finished through work of a pair of dies on a punching machine; the rate of finished products and the working efficiency are improved and the manufacturing requirements of the products are met.

Description

technical field [0001] The invention relates to the structural technical field of a stamping die, in particular to a progressive die. Background technique [0002] In the prior art, the composite blanking die added to the progressive die generally has a structure consisting of an upper die, a lower die, a punch and a die, so that when punching is required, it is relatively complicated and bulky. Larger products cannot be punched, so it is generally used to punch the holes in one step of the mold, and then transfer to another mold for punching and blanking. This working method leads to the manufacturing accuracy of the product It is relatively low, and it is easy to generate large errors when re-aligning the reference, which greatly reduces the yield and work efficiency, so it cannot meet the requirements of manufacturing products. [0003] Therefore, the blanking process of adding a composite die to the progressive die is adopted to shorten the die length and meet the custo...
