A Preparation Technology of Optical Ring Die with Restriction of Hole Retraction

Abstract

The invention discloses a preparation process of a hole retraction-inhibiting optical ring die, which belongs to the technical field of ring die preparation. The shrinkage group penetrates and wraps the die hole of the ring die, so that the embedded control shrinkage group can be filled in the die hole, so that during the heat treatment process, it can effectively reduce the thermal shrinkage of the die hole, thereby effectively inhibiting the die hole. Retraction, which in turn makes the quality of the ring die hole produced better. At the same time, the inner pneumatic shaping column and the outer pneumatic shaping column can extrude and shape the embedded shrinkage control group in both directions. In turn, it can effectively ensure that the embedded shrinkage control group can completely fit the die hole, so that the die hole is tightly filled, and then the embedded control shrinkage group can better inhibit the shrinkage of the die hole. On the one hand, it can effectively reduce the ring die production process. On the other hand, it effectively prolongs the use effect and life of the ring die.

Description

technical field [0001] The present invention relates to the technical field of ring mold preparation, and more particularly, to a process for preparing a hole-retraction-inhibited optical ring mold. Background technique [0002] The ring die is the key part of the ring die pellet machine, which is the key equipment for pellet feed processing, and it is also the main wearing part. Granule equipment. It is a feed processing machine that directly presses particles from crushed materials such as corn, soybean meal, straw, grass, rice husk, etc. Ring die pellet mill is the main feed machinery and equipment for the production of pellet feed. Its performance determines the output of feed processing to a large extent, and occupies a very important position in the process of feed processing. [0003] Because the surface holes of the ring die are too dense, the parts between the holes are small, so that the overall strength of the ring die is not high. Therefore, when heat treatment...

AI Technical Summary

Problems solved by technology

[0003] Due to the dense surface holes of the ring die, the parts between the holes are small, so that the overall strength of the ring die is not high. Therefore, when heat treatment is performed after drilling, thermal shrinkage of the inner wall of the hole is inevitable, resulting in , the die hole on the ring die is deformed to a certain extent, which damages the roundness. On the one hand, the quality of the ring die preparation is affected, resulting in an increase in the rate of defective products. On the other hand, the ring die is used for manufacturing The quality of the product obtained from pellets is not good, that is, the use effect of the ring die is poor
