Abstract

The invention provides a bearing pad coil strip chamfering method. A coil strip comprises a steel layer and an alloy layer which are pressed together. During machine, firstly, the coil strip is hung on a discharge machine, and the end of the coil strip is transferred to subsequent equipment through a conveying mechanism; the coil strip passes through the first press-chamfering device to press chamfers in the two sides of the steel layer; then the end faces of the two sides of the coil strip are cut through an edge trimmer by means of a planar knife; the alloy layer of the coil strip is chamfered through the second chamfering device by means of a chamfering knife; and finally, the chamfered coil strip is wound through a winding machine. By adoption of the bearing pad coil strip chamfering method, burrs are prevented from being generated on the periphery of a bearing pad during forming of the bearing pad, and the quality of the bearing pad is ensured.

Description

Technical field [0001] The invention relates to the field of bearing bush manufacturing, in particular to a processing method for the chamfering of a bearing bush roll. Background technique [0002] Bearings are widely used in current industrial fields. As a very important part of the internal combustion engine, the bearing bush is mainly used to support the crankshaft and reduce the friction between the crankshaft and the connecting rod and the body. [0003] Traditional bearing chamfering uses a tool holder to fix the flat knife, external chamfering tool and internal chamfering tool after the bearing is formed; the bearing holder clamps and locates the bearing, and the tool holder rotates and cuts the chamfer of the bearing. This method can only process one product at the same time at work, and the production efficiency is low. Therefore, a new method for chamfering the bearing bush is needed to improve the continuity and efficiency of bearing bush production and avoid burrs du...
