Embodiment 1

[0040] Embodiment 1: select the cemented carbide substrate 2 that the trade mark is YG16C, carry out the processing of degreasing, deoxidizing layer; The diamond mixture 3 that mixes is packed in the carbon tube 4, and the composition of diamond mixture 3 is: by weight Percentages: Diamond 80%, Silicon 8%, Cobalt 12%. Then put the cemented carbide matrix 2 into it again, prepress the diamond mixture 3, put the carbon tube 4 into the prepared pyrophyllite 1, and carry out the vacuum purification process. During the vacuum process, the temperature is 620 degrees, and the heating time is 2 Hour. Then, between the two ends of the carbon tube 4 and the pyrophyllite 1, a carbon sheet 7, a titanium circle 6 and a conductive steel ring 5 are sequentially loaded to form a composite block. Use the conductive steel ring 5 to energize and heat the synthesis block for 50 seconds, the synthesis pressure is 100Mpa, and the synthesis temperature is about 1580 degrees. The packed pyrophyllit...

Abstract

The invention relates to a method for manufacturing a diamond compound cutting pick head and a diamond compound cutting pick head. The steps of the method are that (1) diamond mixed material is formed by mixing the diamond and metal powders according to the weight percentage of the diamond mixed material of 80 to 82 percent of diamond, 6 to 7 percent of silicon and 12 to 13 percent of cobalt; (2) the surface of a hard alloy is carried out by pretreating, oil removing and detarnishing to form a hard alloy basic body; (3) the diamond mixed material is put into a carbon tube, prepressed for molding and then is arranged into the hard alloy basic body to carry out vacuum purifying treatment; (4) the carbon tube is placed into a pyrophyllite and a conductive steel ring, Ti circle and carbon sheets are arranged between the two ends of the carbon tube and the pyrophyllite to form a compound block; (5) current accesses at the two ends of the conductive steel ring in the compound block and the carbon tube is taken as a heater to ensure six top hammers of alloy to carry out pressurizing on the compound block from six directions of front, back, left, right, up and down during the compounding process; (6) post processing is carried out. The method can manufacture the diamond compound cutting pick head with high anti-impaction and wear-resisting properties.

Description

technical field [0001] The invention mainly relates to the field of hard materials, in particular to a method for manufacturing a diamond composite pick head and the diamond composite pick head. Background technique [0002] Diamond compacts are made by sintering diamond micropowder and cemented carbide substrate under ultra-high pressure and high temperature conditions. They can be divided into two types: ordinary type and special type. They are suitable for exploration, mining, petroleum, coal and other industries. Specific compound sheet includes: cone spherical teeth, spherical teeth, wedge teeth, etc. At present, cemented carbide pick heads are commonly used in the field of mining and mining. Due to the irregular shape and structure of diamond composite pick heads, it is not easy to establish a stable and suitable temperature and pressure field in the high-pressure synthesis chamber, so there is no There are relevant reports. Contents of the invention [0003] The t...
