Problems solved by technology

Since the polycrystalline superhard material composite sheet is made by sintering the polycrystalline superhard material layer on the cemented carbide substrate through high temperature and high pressure, the production process is more complicated, and the polycrystalline superhard material layer and the cemented carbide are easy to delaminate and produce Cracks, resulting in short life of the welding knife

Abstract

The invention discloses a method for manufacturing a composite welding blade, which comprises the following processes of: firstly, forming a groove matched with a tool bit on a matrix; secondly, placing the tool bit in the groove of the matrix; thirdly, filling a solder into a gap between the tool bit and the matrix, and then fixing; and finally, heating the assembled blade, and cooling the heated blade to obtain the composite welding blade. Based on the total mass of the solder, the solder comprises 60 to 95 percent of bonding agent, 25 to 1 percent of reinforcing agent and 15 to 0.5 percent of active agent; and the bonding agent, the reinforcing agent and the active agent are mixed uniformly to form the solder. The bonding agent, reinforcing granules, the active agent and the like are introduced, a transition phase substance is formed between the metal matrix and the composite tool bit in an alloying combination mode, and the transition phase plays a role in firmly connecting the matrix and the composite tool bit and has high strength and thermal stability.

Description

technical field [0001] The invention relates to a composite material welding blade and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of CNC machining technology and the widespread use of CNC machine tools, superhard cutting tools that can achieve high efficiency, high stability, and long-life processing have become increasingly popular, and many advanced cutting concepts have been introduced, such as high-speed cutting , hard machining, high stability machining, turning instead of grinding, dry cutting, etc., superhard cutting tools have become an indispensable means of modern cutting. [0003] Polycrystalline superhard material has extremely high hardness and wear resistance, and is the hardest material among tool materials. At the same time, its friction coefficient is small, it has no affinity with non-ferrous metals, chips are easy to flow out, its thermal conductivity is high, it is not easy to produce built-u...
