Pipe cutting and grinding device

Abstract

The invention belongs to the technical field of cutting equipment, and specifically discloses a pipe cutting and grinding device. The pipe cutting and grinding device comprises a cutting mechanism anda grinding mechanism which are connected to the same rotating shaft, wherein a transmission gear and two fixed pulleys are arranged on the rotating shaft; a rack which is fixed to a machine frame isengaged with the transmission gear; the grinding mechanism comprises a rotating barrel which is fixed to the rotating shaft, and a grinding plate is arranged on the rotating barrel; a square shaft isin sliding connection with the interior of the rotating barrel, and a threaded rod which is in thread connection with the rotating barrel is rotatably connected to the square shaft; and the threaded rod is in sliding connection with a sliding plate, and the sliding plate is in sliding connection with the machine frame. The pipe cutting and grinding device further comprises a conveying roller, a first clamping mechanism and a second clamping mechanism; the first clamping mechanism comprises a clamping block and a fixing block; a sliding rope is connected between the clamping block and the corresponding fixed pulley; the second clamping mechanism is in sliding connection with a working platform; a baffle plate is arranged at the left end of the working platform; and magnetic parts which areattracted to and repelled by each other are arranged between the baffle plate and the second clamping mechanism. According to the scheme, the pipe cutting and grinding device has the advantages that anotch of a steel pipe can be ground while the steel pipe is cut, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of cutting equipment, in particular to a pipe cutting and grinding device. Background technique [0002] Pipe fittings are widely used in today's society. Pipe fittings are parts that connect pipes into pipelines. During the production process of pipe fittings, steel pipes need to be cut, and steel pipes are cut into small sections according to various specifications and sizes. The net weight is relatively large, and the length is also long. The general method is to fix the steel pipe first, and then use a cutting machine to cut the required length. Manual feeding consumes manpower and material resources. The cut steel pipe is cut at both ends after cutting the head and tail. There will be internal and external burrs. Workers generally use a flat file to remove the external burrs, and remove the internal burrs with a conical knife. However, the hardness of the internal burrs after cutting is also greatly imp...

[0002] Pipe fittings are widely used in today's society. Pipe fittings are parts that connect pipes into pipelines. During the production process of pipe fittings, steel pipes need to be cut, and steel pipes are cut into small sections according to various specifications and sizes. The net weight is relatively large, and the length is also long. The general method is to fix the steel pipe first, and then use a cutting machine to cut the required length. Manual feeding consumes manpower and material resources. The cut steel pipe is cut at both ends after cutting the head and tail. There will be internal and external burrs. Workers generally use a flat file to remove the external burrs, and remove the internal burrs with a conical knife. However, the hardness of the internal burrs after cutting is also greatly improved due to the high temperature generated during the cutting process. Therefore, the cut surface of the steel pipe The grinding work needs to consume a lot of time, resulting in a heavy workload for workers, so it is necessary to propose a steel pipe cutting device that automatically grinds the cut
