Equipment for improving tungsten type hard alloy tool scrap knot resistance

Abstract

The invention relates to the technical field of hard alloy tool scrap knot resistance, and discloses equipment for improving tungsten type hard alloy tool scrap knot resistance. A shell is included. Gear plates are fixedly connected to the two side walls in the shell. The surfaces of the gear plates are movably connected with gears. The surfaces of the gears are movably connected with a connectingplate. The part, located on the surface of the connecting plate, in the shell is provided with a sliding rail. The bottoms of the gear plates are movably connected with a meshing plate. The surface of a suction block is movably connected with a spring rod. The end, away from the suction block, of the spring rod is movably connected with an air bag. A compression spring is movably connected in theair bag. The end, away from the air bag, of the compression spring is movably connected with a pressure application plate. The surface of the pressure application plate is movably connected with a fluctuation rod. The spring rod deforms so that force can act on the surface of the air bag, the air bag is pressed, the interior negative-pressure space of the air bag is damaged, suction force is generated, the suction force can be expressed from the suction block, powder is sucked, and accordingly the effect that during pressing, composite carbide powder consumption is reduced is achieved.

Description

technical field [0001] The invention relates to the technical field of hard alloy anti-knife edge, in particular to an improved tungsten carbide anti-knife edge equipment. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy; it has a series of properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Excellent properties, especially its high hardness and wear resistance, remain basically unchanged even at a temperature of 500 ° C, and still have high hardness at 1000 ° C, but the existing tungsten carbide has disadvantages Is the ability to resist edge tumor is poor.

[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy; it has a series of properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Excellent properties, especially its high hardness and wear resistance, remain basically unchanged even at a temperature of 500 ° C, and still have high hardness at 1000 ° C, but the existing tungsten carbide has disadvantages is less resistant to knife edge

[0003] In the prior art, compound carbides are added to the alloy for anti-knife edge. Before adding the compound carbides, the compound carbides need to be compacted and carbonized. Because the compound carbides are WC solid solution at high temperature The solid solution obtained by dissolving WC in TiC or WC in TiC-TaC (NbC) will have a large amount of dust floating in the air when it is compacted, and the compacted composite carbide has a certain temperature. Taking it out will increase the risk of workers' work and is not easy to use. Therefore, an improved tungsten carbide anti-knife edge equipment came into being.
