Edge grinding chamfering device and method for pipe fitting socket

Abstract

The invention provides an edge grinding chamfering device for a pipe fitting socket. The device comprises repair grinding device, a supporting seat for mounting the repair grinding device, and a supporting frame for supporting a pipe fitting; a rotating device comprises a rotating seat mounted on the supporting seat, and an oil cylinder for driving the rotating seat to rotate; the repair grinding device is fixedly mounted on the rotating seat; the oil cylinder is mounted above the supporting seat and drives the repair grinding device to rotate to repair and grind the pipe fitting through the rotating seat; the repair grinding device and the oil cylinder are connected with a PLC system. According to the device, the whole grinding process is automatically controlled through the PLC system, so that manual grinding is avoided, and as a result, the grinding efficiency and the grinding precision can be greatly increased.

Description

technical field [0001] The invention relates to a grinding device, in particular to an automatic chamfering device and method for end face chamfering of a nodular cast iron pipe socket. Background technique [0002] With the demand of the domestic and foreign markets, the current ductile iron pipes must have a great leap and improvement in product quality and appearance. At present, the ductile iron pipes at home and abroad must directly enter the two processes of socket end face grinding and chamfering. , first use a grinder to chamfer the first face of the socket, and then carry out end face grinding in the next process. Purpose: First, after grinding and chamfering, ensure that the zinc is not easy to fall off after spraying zinc on the socket of the pipe, so as to ensure the internal quality of the pipe; second, grind the end face of the socket to ensure the appearance quality of the pipe. In the prior art, the socket end face and chamfering are all manually ground with...

AI Technical Summary

Problems solved by technology

In the prior art, the socket end face and chamfering are all manually ground with a grinder, which is difficult to ensure the grinding quality of the pipe and the angle size of the chamfer, which brings great labor intensity and work efficiency to the workers. Very low, affecting the production rhythm, and it is difficult to guarantee product quality
