Processing method of tubular products by chipless cutting and cutting device thereof

Abstract

The invention provides a cutting device of tubular products of steel pipes by chipless baiting and a processing method thereof, in particular to a processing method of tubular products of rolling bearing rings by the chipless baiting. The method provided by the invention is used for cutting the tubular products into tube blanks with the same length; when the tubular products are cut, a supportingdevice is firstly used for supporting the tubular products between upper scissors and lower scissors; then the upper scissors downward move toward a lower pressing block by the action of pressure andthe lower pressing block synchronously moves in the moving direction of the upper scissors in the same moving speed, so that the upper scissors and the lower scissors move in the way of staggering; finally, the tubular products are cut off without chips. By utilizing the cutting device provided by the invention, the tubular product material is saved and the discharging of carbon is reduced at thesame time; the earth environment is protected and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a processing method for chipless blanking of steel pipes and a shearing device used for the chipless blanking, in particular to a processing method for rolling bearing rings and tubes for chipless blanking and a shearing device, which can be applied to bearings of different specifications It is suitable for blanking blanks of ferrules, and is suitable for chipless blanking of round non-ferrous metal pipes and other metal pipes. Background technique [0002] In the existing bearing production, most of the inner and outer rings of the bearing are made of pipes, and the processing method uses two cutting methods: turning and milling: [0003] In the turning cutting method: the turning cutter is used to cut the pipe on the lathe. Due to the high speed of the turning head, the chips are long and continuous. cut accident. [0004] In the milling and cutting method, the circular saw blade milling cutter is used to cut the pipe with ...

AI Technical Summary

Problems solved by technology

However, compared with the car cut-off, it has high cost and low work efficiency.

[0005] The above two processing methods all have the following problems. Due to the existence of the tool entity, a part of the metal material will inevitably be lost during the cutting process of the pipe, turning it into iron filings, which is a great harm to the metal material. Waste; and the tool loss is relatively large, which makes the production cost higher and the working environment of the workers is poor
