A set of punching dies

Abstract

The invention discloses a positioning punching die. The positioning punching die comprises a male die and a female die. The female die is provided with a punching opening and a feeding opening perpendicular to the punching opening in a cut-through manner. One end of the male die is located above the punching opening and can move into the punching opening, the other end of the male die is connected with a fixing plate, and the fixing plate is fixedly connected with a plurality of sets of positioning assemblies fixing materials to be punched. The male die is internally provided with a plurality of gas channels in a cut-through manner, the gas channels communicate with a gas pipe connector on the fixing plate, and the gas pipe connector is connected with a gas sucking device. According to the positioning punching die, the male die is provided with the gas channels, when punching is carried out, the gas sucking device adsorbs the materials to be punched through the gas channels, then, the male die and the female die are matched to complete punching, after punching is completed, the male die continues to press to send a finished product to an appointed position, an adsorbing device is stopped to put the finished product down, the punching efficiency of the die can be improved, the quality of the finished product obtained after punching is guaranteed, the punching cost is reduced, and the punching requirements of small products are met.

Description

technical field [0001] The invention relates to the technical field of punching dies, in particular to a nested punching die. Background technique [0002] The punching die is usually installed on various presses and machinery equipped with pressure devices, and the specified material is punched out of the desired shape by pressing the die. [0003] Existing metal punching dies such as figure 1 As shown, it includes a discharge plate 101 , a fixed plate 102 , a punch 103 , a die plate 104 , an upper mold base 105 and a lower mold base 106 . Among them, the fixed plate 102 plays the role of fixing the punch 103; the unloading plate 101 mainly plays three functions of unloading, guiding, and pressing; the die plate 104 can be used as the cutting edge of the die, and the die can also be inlaid on it. Insert. Four guide pillars 107 are used to guide and fix between the unloading plate 101, the fixing plate 102, and the concave template 104. [0004] When the above metal punc...

Problems solved by technology

[0005] However, the above metal punching die separates the waste area by punching and retains the finished product area, which is suitable for the punching of "hollowed out" large-format finished products; if a single small product is punched, the above metal punching die cannot be punched at one time Forming requires multiple times of punching or matching with a knife die to complete the punching, and the punched finished products are randomly distributed on the top of the concave template 104 after being unloaded by the discharge plate 101

It cannot meet the current market requirements for product miniaturization
