Rough machining process for bearing ball forming

Abstract

The invention relates to a bearing ball machining technology, in particular to a rough machining process for bearing ball forming. The rough machining process for bearing ball forming comprises the following steps that a, a blank is selected, and the blank is a plate; b, a multi-cavity die is adopted, and a plurality of spherical bodies are synchronously formed on the plate through forging and pressing; and c, a multi-shaft sleeve material drill is adopted, the spherical bodies on the plate are synchronously blanked, and a ball semi-finished product is formed. According to the rough machining process for bearing ball forming, rolled plates can be adopted as raw materials, so that the raw material cost of bearing balls is reduced; a basically spherical ball plate composite body with flashes can be forged through a common die forging machine tool, so that the universality of forging equipment is improved, the general applicability of the process is improved, the technical threshold of bearing ball machining is reduced, the bearing balls can be efficiently produced regardless of enterprise scales and types, and the production channels of the balls are enriched; after forging is completed, all spherical bodies of a ball-plate composite body generated through forging are blanked through a multi-shaft sleeve drilling machine to form a ball semi-finished product, a trepanning drill in an abrasive consolidation form is adopted for drilling, the grinding characteristic is achieved, in other words, burrs of the ball semi-finished product are very few, the pressure is relieved for the subsequent polishing process, and the production efficiency and the production quality of ball rough machining are improved; and in addition, according to the process, one-time forging and pressing are achieved, batch forming is achieved, parallel machining in the real sense is achieved, and process design conditions are provided for large-scale production of the balls.

Description

technical field [0001] The invention relates to the field of bearing ball processing and production, in particular to a rough machining process for forming bearing balls. Background technique [0002] Most of the existing balls are made of wire rods, and then the wire rods are cut and upset to form a spherical basic shape, and then the roundness and surface finish of the balls are improved through grinding processes. On the one hand, the processing cost of this processing method is relatively high. On the other hand, from the perspective of the rough processing process at the beginning, the balls are processed one by one from the cutting of the wire rod to the upsetting round, forming a serial processing mode. There are very few or even only one process serial port. In order to improve the productivity of the ball, the use frequency of the process equipment can only be increased. For example, cutting or upsetting requires about one hundred times per second. On the one hand, ...
