Abstract
The invention discloses a machining method for a coal mining cutter. The method comprises the steps: 1, preparing tungsten steel, placing the tungsten steel into a melting furnace and then melting the tungsten steel; 2, pouring the melted tungsten steel into a die for achieving formation; 3, placing a primary formed die into a hot forging machine, and carrying out hot forging and quenching at 800-900 DEG C; 4, carrying out tempering at 400-500 DEG C; 5, obtaining the cutter and polishing the cutter.
Description
Technical field
The present invention relates to a kind of method of processing of the cutter of mining.
Background technology
Cutter in current coal mining generally adopts the steel alloy of hard to make, and cutter not only easily appears collapsing in this cutter in use, and after the wearing and tearing due to cutter hub, causes de-cutter after long-time use, and mass ratio is poor.
Summary of the invention
The invention provides a kind of method of processing of the cutter of mining, the toughness that it not only can improve cutter, improves result of use, and processing is simple, and cost is low.
The present invention has adopted following technical scheme: a kind of method of processing of the cutter of mining, it comprises the following steps: step 1, prepare material: material is wolfram steel, then wolfram steel is put into melting furnace and melts, step 2, then pours the wolfram steel water after melting into die for molding; Step 3, then puts into warm forming machine by blank mould after moulding and carries out forge hot processing, and carries out the quenching of 800-900 DEG C; Step 4, then carries out the tempering of 400-500 DEG C; Step 5, obtains cutter, finally cutter is carried out to reconditioning.
The temperature of quenching in described step 3 is 850 DEG C.In described step 4, the temperature of tempering is 450 DEG C.
The present invention has with beneficial effect: adopted after above technical scheme, the present invention can improve the toughness of cutter, improves result of use, and processing is simple, and cost is low.
Detailed description of the invention
A kind of method that the invention provides processing of the cutter of mining, it comprises the following steps: step 1, prepare material: material is wolfram steel, then wolfram steel to be put into melting furnace and melt, step 2, then pours the wolfram steel water after melting into die for molding; Step 3, then puts into warm forming machine by blank mould after moulding and carries out forge hot processing, and carries out the quenching of 850 DEG C; Step 4, then carries out the tempering of 450 DEG C; Step 5, obtains cutter, finally cutter is carried out to reconditioning.
