Abstract

The invention relates to a hard alloy gear forming machining method. The hard alloy gear forming machining method mainly comprises the following steps of material preparation, extrusion operation, drying cutting, sintering operation, grinding treatment, checking and packaging and other various procedures. Gear grinding equipment used in the method comprises a bottom plate, a clamping device, a positioning device, a rotating device and a grinding device. The hard alloy gear forming machining method can solve the following problems existing in existing hard alloy gear grinding that a, when a traditional hard alloy gear is ground, manual grinding is carried out by using a file, metal chippings generated during manual grinding affect the air environment of hard alloy gear grinding, the efficiency of manual grinding is low, the machining precision is poor, so that the use reliability is low, and unnecessary economic losses are caused; and b, when existing grinding equipment is used for grinding the hard alloy gear, due to the fact that the clamping of the hard alloy gear is unstable, the grinding effect on the burrs of the hard alloy gear is difficult to guarantee, and the grinding efficiency and quality of the hard alloy gear can be improved.

Description

technical field [0001] The invention relates to the technical field of gear production and processing, in particular to a method for forming and processing cemented carbide gears. 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. Gears made of cemented carbide can improve the hardness and wear resistance of gears. The service life of the gear is improved. After the hard alloy gear is formed, due to the large number of burrs, it is necessary to grind the hard alloy gear. [0003] However, the following problems exist in the grinding of existing hard alloy gears. a. When grinding traditional hard alloy gears, it is necessary to manually use a file for manual grinding, and the me...
