Bearing closed-up punch and machining process thereof

Abstract

The invention provides a bearing closed-up punch. The bearing closed-up punch is mainly used for positioning and fixing of a bearing part, a part which requires bearing mounting is clamped between a punch die and a base, an annular ring is punched in a portion of a bearing hole of the part that requires bearing mounting to limit bearing axial and radial movements, the freedom degree of a bearing is limited by means of the bearing closed-up punch, the operation is simple, and the positioning is good; stretching height of the punch can be finely adjusted, the ejecting height can be easily guaranteed, meanwhile, the punch die is in clearance fit with a shell, the punch die is replaceable, and single component production can be performed in case of unqualified sizes; a corresponding machining process is provided according to the structure of the bearing closed-up punch, the machining efficiency of the bearing closed-up punch can be effectively increased, meanwhile, qualities are guaranteed, and the bearing closed-up punch can be accurately and rapidly fixed and positioned; during forming of the punch die, only one-time angle turning of a small supporting plate is required, the forming of the punch die can be finished only by one forming turning tool, machining steps are reduced, and the machining efficiency is increased.

Description

technical field [0001] The invention relates to a bearing closing punch and a processing technology thereof, belonging to the technical field of mechanical processing. Background technique [0002] The existing bearing closing punches have the following deficiencies: 1. The housing and the punching die are of an integrated structure, and the punching die cannot be replaced. When punching bearings of different sizes, the whole punch needs to be replaced, the processing efficiency is low, and the labor intensity of the workers is high. The accumulative error caused by multiple clamping workpieces will easily lead to low yield of bearing closing punch, which will increase the manufacturing cost virtually; 2. During processing, the verticality, parallelism, depth of the groove and the The protruding height of the punching die is not easy to control. In addition, the equal division control of the punching die and the splitting angle of 45° and 15° are usually used for processing....

[0002] The existing bearing closing punches have the following deficiencies: 1. The housing and the punching die are of an integrated structure, and the punching die cannot be replaced. When punching bearings of different sizes, the whole punch needs to be replaced, the processing efficiency is low, and the labor intensity of the workers is high. The accumulative error caused by multiple clamping workpieces will easily lead to low yield of bearing closing punch, which will increase the manufacturing cost virtually; 2. During processing, the verticality, parallelism, depth of the groove and the The protruding height of the punching die is not easy to control. In addition, the equal division control of the punching die and the splitting angle of 45° and 15° are usually used for processing. 15 degrees, then turn the small pallet back to 0°, use 45° for the inner hole turning tool to turn the punching die at 45°, because the punching die has height dimensions and the size requirements of the arc R, so it is necessary to set the tool multiple times, and pull the small pallet. Angle, not only the processing efficiency is low, but also seriously affect the precision of the bearing closing punch, and then affect the quality of the bearing
