Production Technology of Diamond Wire Busbar Drawing Die

Abstract

The invention discloses a production process of a diamond wire busbar wire drawing die, relates to the technical field of wire drawing dies, and aims at the problems that sintered bodies is too high in hardness and insufficient in toughness, and polycrystalline diamond is low in radiating speed. According to the technical scheme, the production process is characterized in that the production process of the diamond wire busbar wire drawing die comprises the following steps that S2, 30% of copper powder, 20% of nickel powder, 10% of silver powder, 3% of zinc powder, 6% of tungsten powder, 8% ofmanganese powder and 21% of tin powder are uniformly mixed and fully ground, and sintered powder is obtained; and S4, a plurality of die sleeve fillers are clamped in a sintering press, the sinteringbodies are sintered and formed through the sintering press, the pressing pressure is 0.3-0.4 MPa, the temperature is raised to 610-630 DEG C at the rate of 11-14 DEG C / s and maintained for 14-15min, and then the sintering bodies are cooled to 200 DEG C or below with a furnace, and a die sleeve diamond composite is obtained. Through the production process of the diamond wire busbar wire drawing die, the hidden trouble of brittle cracks of the sintered bodies is reduced, the heat conduction performance of the sintered bodies is improved, and the heat dissipation capability of polycrystalline diamond is improved.

Description

technical field [0001] The invention relates to the technical field of wire drawing dies, more specifically, it relates to a production process of a diamond wire bus wire drawing die. Background technique [0002] Diamond wire is the abbreviation of diamond cutting wire, also known as diamond cutting wire or diamond wire. Generally, it is a diamond cutting wire made by inlaying tiny diamond particles on the busbar; the diamond wire busbar drawing die is used On the wire drawing machine, it is specially used for wire drawing to produce diamond wire busbar dies. [0003] Diamond wire bus wire drawing die such as Figure 5 As shown, it includes a mold base 1, a mold cover 11 clamped and fixed with the mold base 1, a polycrystalline diamond 12 arranged on the mold cover 11, and a sintered body 13 filled between the polycrystalline diamond 12 and the mold cover 11; The role of the body 13 is to protect the polycrystalline diamond 12 and reduce the hidden danger of its brittlenes...

AI Technical Summary

Problems solved by technology

[0004] It has been found through practical application that when the sintered body 13 prepared by using the sintered powder formula provided in the cited document is used in a diamond wire bus wire drawing die, the sintered body 13 has too high hardness and insufficient toughness, and the sintered body is brittle. hidden dangers, due to the insufficient thermal conductivity of the sintered body 13, there is a problem of slow heat dissipation of the polycrystalline diamond 12; therefore, a new solution needs to be proposed to solve the above problems
