A high-dimensional shape hard alloy forming agent and its mixing process

Abstract

The invention discloses a high-dimensional shape hard alloy forming agent and its mixing process, which is composed of the following components in weight percentage, wherein: paraffin wax, 15-25%; high-melting point paraffin wax, 15-25%; oil Amines, 1-4%; gasoline, 1-3%; soybean oil, 3-10%; oleamide, 15-25%; normal alkanes, the balance. The present invention can make the extruded material have suitable plastic deformation ability and high dimensionality by selecting appropriate components and appropriate proportions, and the control precision of the pitch of the front and rear ends of the product is high; the extruded material has high Toughness, able to withstand the torsion during the extrusion process, thereby eliminating extrusion cracks; making the removal of the molding agent stable, and avoiding cracks during the intercalation process.

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
