Problems solved by technology

However, due to the many factors affecting the manufacturing of diamond drill bits in an orderly arrangement, the existing diamond particle arrangement methods still have many deficiencies. At present, there are three main ways to realize the orderly arrangement of diamonds: artificial arrangement method, solder adhesion method and template method , but these methods generally have problems such as low arrangement efficiency, poor diamond positioning accuracy, and prone to missing particles. These problems affect the manufacturing accuracy of ordered diamond drill bits, especially in the manufacture of complex shaped diamond drill bits. The problem is more prominent, which hinders the development of the application field of diamond drill bits arranged in an orderly manner

Abstract

The invention discloses a method for preparing an orderly arranged working layer of diamond bits, which comprises the following steps: step 1, uniformly mixing metal powder for making a matrix layer to form a matrix material; step 2, mixing diamond particles with high temperature resistant The epoxy glue is mixed evenly; step 3, setting the orderly arrangement of diamond particles; step 4, preparing the orderly arrangement of diamond bits in the working layer according to the set orderly arrangement of diamond particles. The orderly arrangement of diamond particles is controlled by a glue dispenser, and the matrix powder material is selectively melted with additive manufacturing equipment to finally form the working layer, which can fully ensure the orderly arrangement of diamond particles and improve the orderly arrangement. The controllability of the distribution provides a new method for preparing the working layer of diamond drill bits arranged in an orderly manner.

Description

technical field [0001] The invention belongs to the fields of glue dispensing technology, additive manufacturing technology and diamond production technology, and designs a method for preparing a working layer of diamond bits, in particular relates to a method for preparing a working layer of diamond bits arranged in an orderly manner based on 3D printing. Background technique [0002] As the exploration of energy and mineral resources such as petroleum at home and abroad continues to deepen, the requirements for the life and aging of diamond drill bits with good impact resistance and wear resistance are getting higher and higher. The orderly arranged diamond drill bit is a new type of drill bit that has appeared in recent years. It is different from the traditional diamond drill bit. grain spacing. Therefore, each abrasive particle participates in cutting rock fragments, effectively reducing the mutual interference caused by repeated cutting of abrasive particles, thereby ...
