Description

Technical Field

[0001] The utility model belongs to the technical field of circular saw blade processing, and in particular relates to a circular saw blade processing and forging device. Background Art

[0002] The saw blade processing process usually includes the early cutting and shaping, and the later heat treatment. Between these two processes, there is also a deburring process, which is to grind the surface of the saw blade to remove the burrs around the saw blade and improve the smoothness of the saw blade surface, so as to facilitate the later processing and aesthetics of the saw blade.

[0003] The existing grinding device for processing high-speed steel circular saw blades can only grind one side of the saw blade. When grinding the other side of the saw blade, the saw blade needs to be turned over and re-fixed. Since the saw blade generates heat during the single-side grinding process, the saw blade has a high temperature. It is impossible to turn it over immediately, which affects the subsequent grinding efficiency. If you wear heat-insulating gloves to operate, it is easy to cause safety hazards.

[0004] In order to solve the above problems, the present application proposes a circular saw blade processing and forging device. Utility Model Content
