Method for producing diamond circular saw film base body for mine

Abstract

The invention relates to a method for producing a saw blade, in particular to a method for producing a diamond round saw blade substrate used in a mine. The method comprises the steps as follows: materials selecting: straight carbon steel, spring steel and cutlery steel hot rolling medium plate are selected; baiting: the outer diameter of a blank is equal to the outer diameter of a finished product plus 22mm or plus 28mm; central hole drilling: the hole diameter is Phi 50-Phi 90mm; coarse leveling; coarse grinding: a centreless grinder is used for grinding the two side surfaces of the blank to be smoothing, and 0.5-0.8mm of excess is reserved based on the finished product; saw teeth, a fabrication hole and a transmission hole are formed by cutting by laser; central hole finish machining: a boring is used for processing the central hole to the final size; excircle finish machining: a grinding machine tool is used for processing the outer diameter of the saw blade to the final size; smoothing; accurate grinding: the centreless grinder is used for grinding the saw blade to the thickness size required in the drawing; refined smoothing: final correction is carried out on the saw blade after accurate grinding, and the planeness, the total runout and the stress of the saw blade is adjusted comprehensively until the product is qualified. The invention has the advantages of reducing cost and processing difficulty, saving heat-processing equipment, saving energy and being environment-friendly.

Description

Technical field: [0001] The invention relates to a production method of a saw blade, in particular to a production method of a base body of a diamond circular saw blade for mines. Background technique: [0002] At present, the production of diamond circular saw blades for mines uses medium-high carbon cutting tool steel hot-rolled plates as raw materials. After cutting, tempering, drilling, rough turning, and punching, the overall heat treatment of quenching and tempering is carried out. After rough leveling, it is necessary to use a vertical shaft grinder for side rough grinding, re-leveling, and secondary tempering, and then perform semi-finish leveling, finish turning the inner hole and outer circle, and finally use a vertical or horizontal axis surface grinder to complete the fine grinding of the side of the sheet, and Give the final level. The problems in the above method are: the cost of raw materials is high, the processing is difficult, and the overall heat treatmen...

Problems solved by technology

[0003] The present invention aims to solve the above-mentioned problems existing in the production method of the traditional diamond circular saw blade base body, and provides a saw blade material that allows the use of low-carbon steel materials, which can reduce production costs and processing difficulties; no overall heat treatment can save a lot of heat treatment Equipment, power consumption, energy saving and environmental protection; vertical centerless grinding method is adopted in the side grinding of saw blades, and the side grinding of large diameter saw blades is completed with lower equipment cost and energy consumption cost; In terms of hole and outer circle processing, boring and grinding are used instead of turning processing, and the production method of the diamond circular saw blade substrate for mines can meet the processing requirements without using a large lathe
