Multi-station numerical control bearing rolling machining system and method

Abstract

The invention discloses a multi-station numerical control bearing rolling machining system and method. The multi-station numerical control bearing rolling machining system structurally comprises a top frame, a control panel, a rolling head, a connecting butt plate, a station fixing structure, a sliding bottom frame, supporting feet, a hydraulic rod and a sliding groove, wherein the two or more supporting feet are arranged at the bottom of the sliding bottom frame; the sliding groove is formed in the horizontal middle of the sliding bottom frame; and the hydraulic rod is arranged at one end of the sliding groove. Through the design of a lubricating system and an oil return port, a bearing ring which is located in a groove and is about to be rolled or is rolled is overall lubricated, lubricating oil obtained after lubricating can flow back to the lubricating system along the oil return port to be reutilized, due to the fact that the lubricating system carries the lubricating oil obtained after backflow, impurities are many, two or more filtering structures are arranged, the cleanliness of the lubricating oil in the lubricating system is improved, and the friction force between the bearing ring and the groove is reduced.

Description

[0001] This application is a divisional application with the application date of September 10, 2019, and the invention name of CN201910851271.0 is a multi-station numerical control bearing rolling processing equipment. technical field [0002] The invention relates to the field of bearings, in particular to a multi-station numerical control bearing rolling processing system and method. Background technique [0003] During the processing of the bearing, after upsetting, it needs to be further punched, rolled and expanded. The meaning of rolling and forging is similar. It can be said that rolling and expanding is a kind of forging in a narrow sense.

[0003] During the processing of the bearing, after upsetting, it needs to be further punched, rolled and expanded. The meaning of rolling and forging is similar. It can be said that rolling and expanding is a kind of forging in a narrow sense. Specifically, rolling and expanding is It is a cold forming method to obtain the required shape and precision by extruding the ring-shaped rotary parts to produce plastic deformation at room temperature. Forging can be forged and processed not only at room temperature, but at any temperature. Cold rolling The process requirements are very high, that is, the requirements for pressure, rigidity, guiding precision, overload protection device, and lubrication and cooling system are high. At present, most of the unidirectional rolling machines on the market are mainly because the multi-station CNC bearings are used to roll and place shafts. The fixed groove of the ring is not evenly lubricated, it can only be lubricated in one direction, and the lubricating fluid cannot be recovered, resulting in the spreading of the lubricating fluid at the bottom of the groove, which will easily cause the relative sliding of the rear collar, resulting in a decrease in rolling accuracy
