Abstract

The invention discloses a machining technology for a cold saw blade. The machining technology comprise the following steps that S1, a plate is cut, wherein the plate is cut to obtain a circular saw blade base body with sawteeth; S2, burrs on the surface of the saw blade base body are removed, wherein firstly, the surface of the saw blade base body is de-burred manually by using an angle grinder, and after the relatively large burrs on the surface of the saw blade are removed, a full-automatic de-burring machine is used for carrying out de-burring on the saw blade base body again; and S3, tempering is carried out on the saw blade base body, wherein the saw blade base body undergoes tempering and de-stressing heat treatment, the tempering temperature is 360 DEG C, the tempering time is 4 hours, and the tempering cooling time is 60-72 hours. According to the machining technology, the technological steps are simple, repeated de-burring and cleaning are carried out, the cleanliness degree of the saw blade can be guaranteed during grinding each time, the flatness precision of the saw blade can be improved, through the special angle design of a tool bit, the precision is higher when a workpiece is cut, and the yield of the cold saw blade is improved.

Description

technical field

[0001] The invention relates to the technical field of saw blade processing, in particular to a processing technology of a cold 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 lot of heat is generated during the cutting process. Cold saw blades are different from hot saws because of their processing and cutting principles. Compared with traditional hot saw blades and milling cutters that use traditional high-speed steel and hard alloy as tool materials, cold saw blades have better cutting surface quality and greater precision in sizing. high. Therefore, it has been applied in the production of new profiles and will be widely used in metal material processing. The working temperature of the cold saw machine is generally kept at 40-50 ° C. The material of the processed wo...
