High-dimensional shape hard alloy forming agent and material mixing process thereof

Abstract

The invention discloses a high-dimensional shape hard alloy forming agent and a material mixing process thereof. The high-dimensional shape hard alloy forming agent is prepared from the following components in percentage by weight: 15 to 25 percent of paraffin, 15 to 25 percent of high melting-point paraffin, 1 to 4 percent of oleylamine, 1 to 3 percent of gasoline, 3 to 10 percent of soybean oil, 15 to 25 percent of oleamide and the balance of n-alkanes. According to the high-dimensional shape hard alloy forming agent and the material mixing process thereof disclosed by the invention, by selecting proper components and proportion, an extrusion material is enabled to simultaneously have suitable plastic deformation capacity and higher dimensional shape, and the control precision about screw pitches of the front end and the rear end of a product is high; the extrusion material is enabled to have high toughness and can bear the torsion in the extrusion process, thereby eliminating extrusion cracks; the forming agent is stable in desorption, and cracks generated in the drying in the shade and presintering process are avoided.

Description

technical field [0001] The invention relates to the technical field of hard alloy processing, in particular to a high-dimensional hard alloy forming agent and a mixing process thereof. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has high hardness at 1000 °C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Difficult-to-machine materials such as stainless st...

AI Technical Summary

Problems solved by technology

In the process of processing cemented carbide into tools, it needs to be extruded with a molding agent. The existing extrusion molding agent process can stably produce rods, straight-hole pipes and other products, but the lack of toughness in the production of spiral products leads to extrusion. Cracks during pressing or during drying and removal of forming agent
