Electroplating hot-pressing diamond saw blade and method for manufacturing same

Abstract

The invention relates to a electroplate thermal compress diamond saw blade and relative producing method, which comprises a saw blade basic body (3), whose external edge has a hole groove matching the end shape of thermal compress T-shape blade head (2); the end of thermal compress T-shape blade head (2) is embedded into the hole groove; said thermal compress T-shape blade head (2) and the external edge of saw blade basic body are both made from electroplate nickel cobalt alloy composite layer which contains artificial diamond. And said thermal compress T-shape blade head (2) is made by mixing the artificial diamond and metallurgy powder to be arranged into the T-shape graphite mould, to be thermal compressed in 700-800Deg. C. And the mass ratio between the artificial diamond and metallurgy powder is 1:20; the granularity of artificial diamond is 46-70 deals; the metallurgy powder is formed by bronze powder, cobalt powder, nickel powder, manganese powder and carbonized tungsten, while the mass percentages are: bronze powder in 35, cobalt powder 1, nickel powder in 5, manganese powder in 5, and carbonized tungsten in 54. The invention can realize high blade strength of diamond saw blade, with better quality, simple process and short producing period.

Description

technical field [0001] The invention relates to a diamond saw blade and a manufacturing method thereof, in particular to a diamond saw blade and a manufacturing method thereof for cutting cement pavement expansion joints, concrete products, refractory materials, ceramics, gypsum boards and other building materials. Background technique [0002] In the prior art, there are two methods for producing diamond saw blades by hot pressing. One is to directly press the synthetic diamond and metal powder on the edge of the saw blade base by hot pressing; Artificial diamond and metal powder are pressed into impregnated cutter heads, and then the cutter head is welded to the blade of the base body with a high-frequency welding machine. The hot pressing means used in the above two methods must make the diamond withstand a high temperature of about 1000°C, so that the diamond Graphitization and thermal cracking will occur on the surface, thereby reducing the original strength and hardnes...

Problems solved by technology

[0002] In the prior art, there are two methods for producing diamond saw blades by hot pressing. One is to directly press the synthetic diamond and metal powder on the edge of the saw blade base by hot pressing; Artificial diamond and metal powder are pressed into impregnated cutter heads, and then the cutter head is welded to the blade of the base body with a high-frequency welding machine. The hot pressing means used in the above two methods must make the diamond withstand a high temperature of about 1000°C, so that the diamond Graphitization and thermal cracking will occur on the surface, thereby reducing the original strength and hardness of the diamond. High-frequency welding will cause the diamond to be thermally damaged again, and the bonding strength is not high, and the saw blade cannot withstand large impacts

Invention patent CN86107053A discloses a method for preparing diamond saw blades with embedded cutter heads produced by electroplating. This method completely avoids diamond thermal damage and improves the use effect of diamonds. The disadvantage is that it takes a long time to produce diamond cutter heads. , the shape of the cutter head is not easy to control

ZL02147751.5 announced an embedded cutter head is polycrystalline diamond, which is characterized by hard and wear-resistant cutter head and long service life, but this product can only cut soft building materials, and the scope of use is limited
