Manufacturing technology for circular saw blade of metal ceramic cold saw

Abstract

The invention provides a manufacturing technology for the circular saw blade of a metal ceramic cold saw. The manufacturing technology comprises the following steps of first, cutting a plate to obtaina circular piece body with a plurality of tooth sockets formed in the periphery in a circumferential distribution manner; second, making the stress of the piece body meet the requirements; third, making the flatness of the piece body meet the requirements; fourth, positioning blades in the tooth sockets of the piece body, and welding the blades to the piece body with lasers after the symmetry degree of the blades relative to the piece body meets the requirements; fifth, carrying out manual flattening on the piece body; sixth, carrying out coarse grinding and finishing on the piece body in sequence; and seventh, forming a chip separation groove in the front end of each blade and arranging the chip separation grooves in every two adjacent blades on the two sides of the symmetric line of theblades in a staggered manner. With the manufacturing technology for the circular saw blade of a metal ceramic cold saw, the efficiency can be improved, the rate of finished products can be increased,the man hour for inspection and flattening can be shortened, the manufacturing cost can be reduced, and the production bottleneck of the circular saw blade of a metal ceramic cold saw is broken through.

Description

technical field [0001] The invention relates to a manufacturing process of a cermet cold saw circular saw blade. Background technique [0002] The traditional "hot saw" circular saw blade cuts metal, just like a woodworking circular saw blade processes wood. There is intense friction between the saw teeth and the material being cut, and a large amount of heat is generated during the cutting process. Different from the above-mentioned hot sawing, cold sawing has a different cutting principle, resulting in a "cold sawing" cutting effect. Compared with the traditional hot saw saw blade milling cutter with traditional high-speed steel and hard alloy as the tool material, the cold saw blade milling cutter saws better cutting surface quality and high sizing accuracy. Therefore, it has been applied in the production of new profiles, and will be more widely used in metal material processing. The working temperature of the cold saw machine is generally kept at 40-50°C. The material...

Problems solved by technology

However, cold sawing requires high process conditions, high manufacturing costs, long inspection and leveling hours, and low yield rate, which has become a bottleneck in the production of high-efficiency and high-quality metal-ceramic cold saw circular saw blades.
