A method for manufacturing bearing steel chips and steel grit and its sorting device

Abstract

The invention discloses a manufacturing method and separation device for bearing steel chip steel grits. The manufacturing method comprises the following steps of: quenching, crushing, separating and tempering chips; and further recycling the treated bearing steel chips to manufacture high-quality steel grits. The manufacturing method has the characteristics of simple machining process, easiness in implementation and the like. The separation device comprises a vibration cropping mechanism and a separation mechanism; the separation mechanism comprises a stander and a conveying mechanism; the conveying mechanism is a conveying belt; the inclination angle of the conveying belt can be adjusted and the conveying belt can be movably arranged on the stander in the high end direction, so that chips of granular structures can roll in a low end direction of the conveying mechanism; and the vibration chopping mechanism is matched with the near low end of the conveying belt. Through the separation device, the chips of flat structures which are not suitable to be used as the steel grits can be removed from the mixed chips, and obstacles are removed for manufacturing the steel grits by using the bearing steel chips; and the separation device has the advantages of simple structure, convenience in operation and the like.

Description

technical field [0001] The invention relates to a processing technology of steel grit, in particular to a manufacturing method and a sorting device of bearing steel swarf steel grit. Background technique [0002] In bearing manufacturing, it is often necessary to process the workpiece, such as forming, cutting, spraying, etc. In particular, after the workpiece is cut, many chips will inevitably be generated. How to use these high-quality resources to turn waste into treasure is worthy of attention. At present, there are many ways to recycle the chips cut from the workpiece. For example, some chips are melted and then processed into other objects; some chips are collected and pressed into blocks, but at present However, it is rare to directly make bearing steel chips into steel grit for stone cutting, and there is no successful report. The reason is that the chip thickness varies greatly, so the steel grit produced inevitably has some flat particles, which often cut the sto...
