Abstract

The invention relates to a complex molding comb tooth cutter which solves the problem that an edge of a coarse cutting tooth of the existing cutter is high in damage probability, the smooth degree of the surface of a machined workpiece is poor, and the cutter is short in service life. A novel edge reinforcing belt structure-variable scale edge reinforcing belt structure of the complex molding comb tooth cutter is provided according to the change trend of the cutting layer thickness of the cutting edges in different sections of the cutter in the cutting face, namely the arc corner radius of a reinforcing belt of the cutting edges of different sections of the complex molding comb tooth cutter has different design values.

Description

Technical field:

[0001] The present invention is related to the structure of the reinforcing band of the cutting edge of the complex shaped comb tooth tool. Background technique:

[0002] Edge strengthening is to passivate the cutting edge of a tool with a sharp edge, so that the edge of the cutting edge has an arc-shaped edge or other forms of structure. Practice has proved that after the cutting edge is strengthened, the chipping phenomenon of the cutting edge is reduced, and the performance of the cutting tool is greatly improved. After years of research, we have developed the edge strengthening belt structure for different occasions, which greatly improves the cutting performance of the tool. At the same time, various cutting edge strengthening treatment methods such as sand dulling, brushing, and polishing have been developed.

[0003] However, scientific research and technical personnel have not conducted in-depth research on the edge strengthening of complex shaped ...

Embodiment Construction

[0020] The complex forming comb cutter is divided into fine cutting teeth and rough cutting teeth, the number of teeth is 2, and there is one fine cutting tooth and one rough cutting tooth. figure 1 , figure 2 For the comb cutter in the middle, the teeth on the right are fine cutting teeth, and the teeth on the left are rough cutting teeth. figure 1 , 2 The shown complex forming comb cutter consists of straight blade 1, straight blade 3, straight blade 5, straight blade 7, straight blade 9, straight blade 11, straight blade 13, straight blade 15, straight blade 17, arc blade 2, Arc edge 4, arc edge 6, arc edge 8, arc edge 10, arc edge 12, arc edge 14, arc edge 16 form. Among them, the cutting edges 1-9 are fine cutting teeth, and the cutting edges 10-17 are rough cutting teeth. The dimensions of the edge strengthening band described below are defined as the fillet radius of the cutting edge.

[0021] Dimension R of the edge strengthening band in the rough cutting tooth ar...
