A floating progressive die for deep drawing with material

Abstract

The invention belongs to the field of progressive dies, and particularly relates to a floating type strip material drawing progressive die. The die comprises an unloading plate used for pressing a material strip; the unloading plate is connected with an upper die holder through an upper die elastic assembly; a floating female die plate is further arranged over a fixed female die plate and connected with the fixed female die plate through a lower die elastic assembly; the floating female die plate is provided with an avoiding hole in the vertical direction; the fixed female die plate is provided with a boss part in an extending manner; the floating female die plate is sequentially provided with a notch hole and a first drawing hole in the material strip machining direction; the positions, from a second drawing hole of the die to a final drawing hole, of the die are arranged at the position of the upper surface of the boss part; and a material stripping hole of the die is located in the floating female die plate and arranged behind the position of the final drawing procedure of the die. The floating type strip material drawing progressive die has the beneficial effects of being small in body type, convenient to use and high in production stability, and the finished product quality of products can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of progressive dies, and in particular relates to a floating progressive die for drawing with material. Background technique [0002] Deep drawing, also known as drawing, stretching, calendering, etc., refers to the use of molds to stamp flat blanks of a certain shape obtained after punching into various open hollow parts, and then reduce the diameter and increase the height of the open hollow blanks until A mechanical processing technology for cutting and stripping. Existing floating progressive dies for deep drawing with material usually include an upper die assembly consisting of an upper die plate, an upper die backing plate, a punch fixing plate and a stripping plate, and a fixed concave die plate, a lower die backing plate and a lower die plate. Formed lower mold assembly. When in use, the continuous strip enters the mold from the front end of the mold step by step, and is processed step by step until it is di...

Problems solved by technology

However, the increase in the distance between adjacent processes or the number of meaningless empty steps often leads to an increase in the size of the mold, which in turn increases the cost of mold manufacturing and is extremely inconvenient to use
