Description

Half-divided chamfering rolling cutter

Technical Field

The utility model relates to the technical field of chamfering rolling cutters, in particular to a split half chamfering rolling cutter.

Background

At present, after the tooth surface of the gear is extruded by a chamfering cutter, a tiny bulge is formed, the height of the bulge is generally 0.05-0.2 mm, the bulge is very hard and has the hardness of more than HRc60 after heat treatment, and the bulge can damage a grinding wheel of the grinding tooth and a honing wheel of the honing during grinding and honing, therefore, 2 measures are generally adopted to protect the grinding wheel and the honing wheel, namely, one step of rolling procedure is added, and the bulge of the tooth surface is pressed down to be within 0.02mm by using a rolling wheel; another is to add a single finishing step to remove the protrusions by hob cutting, however, these added steps necessarily increase the manufacturing cost and result in limited popularization of the post-heat treatment tooth grinding and honing process.

The chamfering process and the rolling process are mutually independent, and under the current technical level condition, the chamfering cutter and the rolling cutter are different cutters and cannot be precisely combined together. The main method for omitting the rolling procedure is taken as a direct thought for improving the technology, and no effective method disclosure can be realized;

in the patent with publication number CN202943336U, an integral rolling and chamfering compound cutter is proposed, which is designed with a rolling part with a rolling blade 5 and a chamfering part with a chamfering blade 2 at the same blade 1, and the center distance between the chamfering blade and the rolling blade is the same, the total teeth number in the circumferential direction is the same, and in addition, the phase difference and the axial position difference between the blades must be balanced and coordinated, so that the cutter can be manufactured smoothly;

it still has the drawback that the above-described device is not satisfactory when only chamfering or only rolling is required.
