[0002] Steel bearings are a type of mechanical component that is widely used in many fields. Here is a detailed introduction to steel bearings: Steel bearings are steel parts that contain a fine oil film or lubricant inside to reduce friction and wear between the shaft and the bearing, allowing the shaft to rotate smoothly. Advantages: Anti-fatigue and anti-friction: Steel bearings can withstand the harsh working environment of high speed, high temperature and high pressure due to the fine internal lubricating film or lubricant. Good durability: Steel bearings have excellent durability and can maintain stable performance for a long time.

[0003] During the production process of steel bearings, the shape of the bearing sleeve is unstable in the hot-melt state and is not a regular circle.

The existing stamping operations are mostly single stamping, and the production stamping efficiency is low. At the same time, the position of flushing and cooling cannot be adjusted over a large range. Based on this, a trimming device for steel bearing processing is provided. Utility Model Content

A plurality of positioning holes 12 are opened inside the slide groove 9. A support plate 18 is fixedly installed on one side of the top of the mounting frame 1, and a pneumatic telescopic column 17 is fixedly installed on the bottom of the support plate 18.

A slide groove two 14 is fixedly installed on the bottom of the guide groove one 4, and a slider two 15 is slidably installed inside the slide groove two 14. A pneumatic telescopic rod 3 is hinged on the bottom of the slider two 15, and a baffle 26 is fixedly installed on one side of the limit fork 21.

[0021] The working principle of the above technical solution is as follows: when in use, the guide groove 14 is connected to the discharge point of the thermoformed bearing ring, the bearing ring enters the inner side of the guide groove 14, the pneumatic telescopic rod 3 is extended through the slider 2 15 and the slide groove 2 14 to lift the guide groove 14, so that the bearing ring rolls to the inner side of the guide groove 2 16, and is guided to the guide plate 22 through the guide groove 2 16. At this time, the pneumatic telescopic column 17 is extended so that the limit fork 21 inserts the bearing ring into a limit position, and the bearing ring rolls and fits one side of the limit fork 21.
