Method for machining roller cage

Abstract

The invention provides a method for machining a roller cage, which is used for machining a flat plate into the roller cage. The method sequentially comprises the following steps of a drafting process, a perforating process, an edge folding process, a rolling process and a punching process, wherein the flat plate is subjected to the drafting process, the perforating process and the edge folding process to form a pipe sleeve, and the two ends of the flat plate respectively form a closed-end edge and an opening-end edge; after the pipe sleeve is subjected to the rolling process, and the inner surface and the outer surface of the pipe sleeve form an opposite convex-concave structure; finally the convex-concave structure is subjected to the punching process to form a plurality of through holes, thus the roller cage is formed. Therefore the method for machining the roller cage has high material utilization rate and low configuration cost and loss, and the requirements of reducing the manufacturing cost can be met.

Description

technical field [0001] The invention relates to a roller cage, in particular to a manufacturing method of the roller cage. Background technique [0002] see figure 1 As shown, it is an exploded view of the structure of the existing one-way clutch 1, which mainly includes a plurality of rollers 2, a first collar 3, a second collar 4 and a roller cage 5, wherein the first collar 3 and the second collar 4 are fitted and rotate relative to each other, and at least one roller bearing 6 can be arranged between the first collar 3 and the second collar 4, and the preferred number is one or two sets . In addition, the first collar 3 is sleeved inside the second collar 4, and the first collar 3 has a plurality of pockets 7 corresponding in number to the plurality of rollers 2, and the bottom surface of the plurality of pockets 7 is Inclined, and the distance between the deeper part and the second collar 4 is greater than the diameter of the roller 2 , and the distance between the s...

Problems solved by technology

[0004] see again figure 2 As shown, the existing roller cage 5 is to be made by using a ring body 8 as the raw material, and the roller cage 5 is formed by turning the mechanical processing method. However, in this processing method, it must remove quite a lot. Therefore, its material utilization rate is not good, which will cause waste of resources, and its machining accuracy is not easy to control through turning, and chips are generated during processing, which increases the time for subsequent processing, and its processing method not only reduces processing time Long, tool wear, and many process steps, resulting in high process costs, it is difficult to meet the demand for cost reduction
