Anti-adhesion punch for powder molding

Abstract

The invention discloses an anti-adhesion punch for powder molding, which is characterized in that small air vents are distributed on the punch perpendicularly and evenly, a ventilating pipe is arranged at each of the air vents in a matching mode, and ventilating pipes are directly connected with a peripheral equipment air compressor through an air separating joint. When the anti-adhesion punch for powder molding works, air films can be prevented from being formed between the punch and powder, the adhesion of the punch to the powder is effectively prevented, and the quality of punch stamping powder molding product surface is not affected simultaneously.

Description

technical field [0001] The invention relates to powder forming equipment technology, in particular to a powder forming anti-adhesion punch. Background technique [0002] Stamping is a technology that can directly form powder materials through various molds, and it is also a rapid prototyping processing method that has developed rapidly in the processing field. At present, there are three ways to prevent sticking in the stamping process: one is to add anti-sticking ingredients to the raw materials by changing the composition of the material. This method needs to change the ratio of raw materials, which not only easily affects the product quality, but also increases the cost of manufacturing the product; the second is to change the surface quality of the punch of the stamping machine so that the contact surface of the punch does not stick to the material. This method needs to use a special process to treat the surface of the punch when processing the punch, so that the punch ...

This method needs to change the ratio of raw materials, which not only easily affects the product quality, but also increases the cost of manufacturing products; the second is to change the surface quality of the punch of the stamping machine so that the contact surface of the punch does not stick to the material

This method needs to use a special process to treat the surface of the punch when processing the punch, so that the punch forms a non-stick surface, thus increasing the manufacturing cost and maintenance cost of the punching machine. At the same time, after a period of actual use, the punch will also be The anti-adhesion surface of the head is worn away, which not only increases its use cost, but also has a short service life and diminishes the use effect; the third is to apply anti-adhesion liquid on the contact surface of the punch

This method needs to apply anti-adhesion liquid before each stamping, not only the anti-adhesion liquid applied will be pressed into the formed product during stamping, which will affect the product quality, but also the process operation is cumbersome, which increases the operating strength of the workers, and there are also disadvantages. safety factors
