Problems solved by technology

[0002] In the production process of medical drugs, crushing is a very routine processing step, but the current crushing has not carried out detailed research on the crushing parts. After detailed research on the existing crushing parts, it is found that most of the existing crushing parts use It is conventional high-hardness steel, but because many of the pharmaceutical raw materials also have considerable hardness, it is easy to damage the broken parts when crushing these pharmaceutical raw materials
There are also some precise crushing parts made of cemented carbide (such as WC-Co), but this kind of cemented carbide is generally very expensive, and it is a bit wasteful to use such cemented carbide as a broken part of medicine

Abstract

The invention relates to a preparation method for a drug crushing shaft. The preparation method comprises the following steps of smelting, annealing after die casting, deep cooling, partial quenching, tempering, finishing and the like. Through the reasonable arrangement for all steps, the hardness of the crushing shaft is improved, under the situation of no-adding cost, the hardness of the working surface of a crushing cutter is greatly improved, and meanwhile, by reasonably limiting the mode of the crushing cutter, the crushing cutter can be more durable and stronger.

Description

technical field [0001] The invention belongs to the field of medical equipment and alloy heat treatment, and in particular relates to a preparation method of a drug crushing shaft. Background technique [0002] In the production process of medical drugs, crushing is a very routine processing step, but the current crushing has not carried out detailed research on the crushing parts. After detailed research on the existing crushing parts, it is found that most of the existing crushing parts use What is used is conventional high-hardness steel, but because many of the pharmaceutical raw materials also have considerable hardness, it is easy to damage the broken parts when crushing these pharmaceutical raw materials. There are also some precise crushing parts made of cemented carbide (such as WC-Co), but this type of cemented carbide is generally very expensive, and it is a bit wasteful to use such cemented carbide as a broken part of medicine. Therefore how to develop a kind of...
