Environmentally friendly preparation method of medium and small diameter diamond circular saw blade substrate

Abstract

The invention discloses an environment-friendly preparation method for a base body of a diamond circular saw blade with a medium and small diameter, which is carried out according to the following steps: 1) raw material selection: select a steel plate material after high-precision rolling; 2) blank cutting: cut on a steel plate A circular blank with teeth on the edge is produced, and the inner hole is cut at the center of the circular blank; 3) Heat treatment: the saw blade base blank is quenched with dry pressurized quenching equipment, and after quenching is completed, it is returned to the pressurized box furnace. Fire; 4) Leveling and stress control: Use manual hammering and multi-roller leveling machines to correct the flatness of the saw blade base. After leveling, use a rolling machine to roll the saw blade base to complete the stress adjustment; 5) Finishing inner and outer circles: process the inner and outer diameters of the saw blade base to the final size; 6) Fine leveling and general inspection. The invention does not need a grinding process, saves pollution and energy consumption caused by saw blade grinding, adopts dry pressurization and quenching, improves environmental protection conditions, and finally obtains a saw blade base with high flatness and surface corrosion resistance.

Description

technical field [0001] The invention relates to a production method of a saw blade, in particular to an environment-friendly preparation method for a base body of a diamond circular saw blade with a medium and small diameter. Background technique [0002] The diamond circular saw blade base is an important product for making diamond circular saw blades.

Problems solved by technology

However, the grinding process of the saw blade will generate a lot of waste water and consume a lot of electric energy, which will increase the environmental protection burden; at the same time, the depreciation of the grinding machine, the use of consumables, and the consumption of labor will increase the production cost.
