Needle polishing process

Abstract

The invention discloses a roller pin polishing technique. The roller pin polishing technique comprises the following steps that 1, workpiece blanks are poured into a rolling barrel polisher to be roughly polished for 5-8 h, and obvious burrs of workpieces are removed; 2, the roughly-polished workpieces are poured into another rolling barrel polisher to continue to be finely polished for 30-40 h, and thus products are formed; and 3, the finely-polished formed products are fished out and poured into another clean rolling barrel polisher to be cleaned for 5-6 h, so that the outer surfaces of theworkpieces are bright and clean. According to the disclosed roller pin polishing technique, the products are polished through the multiple steps and different polishing environments, the polishing efficiency is improved, and product glossiness is higher.

Description

technical field [0001] The invention relates to the technical field of needle-rolling processing, in particular to a needle-rolling polishing process. Background technique [0002] The needle rollers are generally installed between the outer ring and the inner ring of the needle roller bearings. During operation, the rolling of the needle rollers is used to reduce the frictional resistance between the two relative moving parts. In the prior art, one type of bearing needle roller has semicircular ends on both ends. When this kind of bearing needle roller is used in practical applications, it mainly relies on the rolling of the needle roller to reduce the friction between the two relative moving parts. purpose of resistance. [0003] In the processing and production of needle rollers, polishing is an indispensable processing step. The existing needle roller polishing usually directly pours the needle roller blank into the polishing machine for one-time polishing, and then cle...

Problems solved by technology

[0003] In the processing and production of needle rollers, polishing is an indispensable processing step. The existing needle roller polishing usually directly pours the needle roller blank into the polishing machine for one-time polishing, and then cleans it. This method has the following disadvantages: Needle from blank to preliminary forming to final forming is obtained by polishing and removing corner burrs step by step, because the most original corner burrs of needle rolling blanks are the most, so the corresponding treatment method should be a process of gradually changing polishing conditions, while in the prior art Usually all the polishing raw materials are poured into the polishing machine at one time, so the polishing efficiency is low and the product polishing quality is not good
