Abstract

The invention discloses a diamond composite drill bit manufactured by a hot pressing method. The diamond composite drill bit comprises the following components in parts by mass: 20-25 parts of diamond, 31-35 parts of a main body material, 30-36 parts of a binding material and 4-16 parts of other materials, the main body material is aluminum-based alloy powder, and the aluminum-based alloy powder comprises Al-Fe alloy powder, Al-Cr alloy powder and Al alloy powder; the bonding material is bronze powder and high-purity copper powder; and the other materials are Co, Mn and Ni. The mechanical performance of the diamond composite drill bit can be effectively improved, the working efficiency is guaranteed, and meanwhile the service life is long.

Description

Technical field [0001] The present invention belongs to the field of diamond drill bit technology, specifically relates to a hot pressing method to manufacture diamond composite drill bits and processing technology thereof. Background [0002] The drill bit that makes the cutting edge is called the diamond drill bit. The drill bit is a one-piece drill bit, the entire drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, is one of the three new technologies of the world's drilling in the 1980s. On-site use proves that when the diamond drill bit is drilled in the soft and hard formation, it has the advantages of fast speed, more inching, stable work, fewer downhole accidents, and good well quality. At present, the diamond drill bits on the market that are thermoformed by hot pressing usually have short service life, poor mechanical properties, long sintering time, poor thermoforming, and the working depth...
