Description

Alloy tool for chamfering

technical field

The utility model belongs to the technical field of alloy cutting tools, in particular to an alloy cutting tool for chamfering.

Background technique

Chamfering refers to the processing of cutting the corners of the workpiece into a certain slope. Chamfering is to remove the burrs produced by machining on the parts, and also to facilitate the assembly of the parts. Generally, chamfering is made at the end of the part. When chamfering, various types of tools can be used to chamfer it. After retrieval , and the application number is "CN201110415017.X" which discloses "cutter for steel pipe chamfering", which records "the effect is: because the steel pipe chamfering cutter includes a handle and a cutter head arranged at the front end of the handle, the cutter The head includes two V-shaped cutting edges, each of which includes an inner cutting edge for chamfering the inner hole of the steel pipe and an outer cutting edge for chamfering the outer peripheral end of the steel pipe. The two cutting edges are arranged symmetrically with respect to the axisymmetric plane of the handle. Therefore, the tool is rotated by the power device, and the end of the steel pipe is leaned against the cutting edge. The inner cutting edge and the outer cutting edge contact and chamfer at the same time, thereby improving the chamfering efficiency and reducing the cost.” Using the V-shaped cutting edge can indeed improve the chamfering efficiency and reduce the cost, but in actual use, the integrated The tool has poor heat dissipation and is easy to fuse after long-term use. Based on this, it is more practical to provide a tool with better heat dissipation performance.
