Embodiment Construction

[0019] The present invention will be described in detail below in combination with specific examples.

[0020] Methods to prevent stamping parts and waste from jumping out of the die include the following methods:

[0021] Method 1. Change the shape of the punch: change the shape of the punch from a flat bottom to a broken line, an arch or a tiny cone;

[0022] Method 2. Appropriate treatment of the die hole: Grinding the cutting edge of the die hole that can effectively keep the workpiece or waste in the die hole without increasing the burrs on the workpiece;

[0023] Method 3. Install a jacking device on the punch: install a thimble or spring on the punch that can push the workpiece or waste from the end face of the punch;

[0024] Method 4. Blow compressed air: There is a nozzle on the punch that can effectively push the workpiece or waste away from the punch;

[0025] Wherein, in the method 1, when the punch moves upwards from the die, the punched workpiece or waste will...

Abstract

The invention relates to a method for preventing a stamping part and a waste material from jumping out of a female die. The method comprises the following steps in sequence that method 1, the shape ofa male die is changed, specifically, the shape of the male die is changed from a flat bottom to a broken line, an arch shape or a small conical shape; method 2, proper treatment is carried out on a female die hole, specifically, under a condition that burrs on a workpiece are not increased, the workpiece or the waste material can be effectively kept in a cutting edge of the female die hole in thefemale die hole by grinding; method 3, a jacking device is arranged on the male die, specifically, an ejector pin or a spring capable of pushing downwards the workpiece or the waste material from theend face of the male die are installed on the male die; and method 4, compressed air is blown, specifically, a nozzle which can effectively push the workpiece or the waste material away from the maledie is arranged on the male die. According to the method, the risk of damage to the die is reduced, the production safety is ensured, and the situation that the production is stopped is avoided.

Description

technical field [0001] The invention relates to a method for preventing stamping parts and waste materials from jumping out of a die, and belongs to the technical field of industrial processing. Background technique [0002] The use of multi-station progressive dies on high-speed presses can efficiently produce complex-shaped sheet metal parts. The structure of the multi-station progressive die is complex, and sometimes a die consists of hundreds of parts. In order to meet the requirements of high-speed operation, this kind of mold must be made of high-strength mold material and processed by precision machining. The design and manufacture cycle of high-speed multi-station progressive die is long and the cost is high. In order to ensure the smooth progress of the stamping process and to prevent the mold from being damaged, the high-speed multi-station progressive die is usually equipped with various detection and protection devices. [0003] When stamping at high speed, th...
