Annular bearing forging triple-package forging technology

Abstract

The invention relates to an annular bearing forging triple-package forging technology belonging to the technical field of bearing forging and mainly solving the problem of lower stock utilization in the traditional annular bearing single and double-package forging technology. The technology is mainly characterized in that: (1) a steel section with the weight of 1.500-2.700kg and the diameter of 55-70 is heated to forging temperature, divided into two parts, i.e., an annular big bloom and an annular medium-small bloom, after the processes of upsetting and package separation; (2) the annular big bloom is made into a big annular bearing forge by the processes of ring rolling, restricking and cooling; (3) the annular medium-small bloom is separated into two parts, i.e., an annular medium bloom and an annular small bloom, after the processes of upsetting and package separation; (4) the annular medium bloom is made into a medium annular bearing forge by to the processes of ring rolling and cooling; and (5) the annular small bloom is made into a small annular bearing forge by the processes of ring rooling, extrusion, punching and cooling. The invention mainly adopts a novel technology of punching-expanding horizontal package separation and the annular bearing forging triple-package forging technology, thereby realizing the simultaneous production of annular bearing forgings in big, medium and small sizes.

Description

technical field The invention belongs to the technical field of bearing forging. In particular, it relates to a three-set forging process for ring bearing forgings. Background technique At present, most of the ring bearing forgings in automobiles, motorcycles and machinery are produced in a single piece on pressure equipment such as crank presses and hole reaming machines. , heavier weight, lower material utilization. How to further reduce core weight and improve material utilization. Finding a new forging process method is of great significance for reducing production costs. Contents of the invention The object of the present invention is to provide a triple-set forging process with high material utilization rate and low production cost, which is suitable for the production of ring bearing forgings in small batches or large batches. The technical solution of the present invention is: a three-set forging process for ring bearing forgings, which is characterized in th...
