a cutting machine

Abstract

The application provides a cutting machine including: a frame, a clamping mechanism, a hob device, a driving wheel and a power device. The hob unit includes: a cutting wheel seat, a cutting wheel assembly and a driving assembly. In the cutting machine provided by this application, the pipe is clamped on the hob device, so that the side wall of the pipe is close to the middle position of the cutting wheel assembly, the cut of the cutting wheel assembly is perpendicular to the pipe, and then the cutting wheel seat and the driving assembly move, Make the blade of the cutting wheel assembly cut into the pipe wall, and the power device drives the cutting wheel assembly to rotate around the pipe through the driving wheel. With the advancement of the driving assembly, the continuous feeding will roll and cut the pipe until the pipe is cut off. During the process, no iron filings are formed, which reduces the loss of pipes. The cutting wheel assembly is used to cut the pipe by rolling, and the contact mode between the blade of the cutting wheel assembly and the raised ribs inside the pipe changes, that is, the blade does not directly form impact contact with the ribs, which reduces the damage of the blade accordingly probability.

Description

technical field [0001] The present application relates to the technical field of machinery, and in particular, to a cutting machine. Background technique [0002] During the manufacture of idlers for belt conveyors, it needs to be cut from the pipe according to the specified length of the idler cylinder, and then processed into a standard idler cylinder. Due to the relatively large demand for idlers, special cutting tools are generally used. The pipe machine cuts the pipe. The cutting method of some pipe cutting machines is to use the lathe to cut the pipe, that is, the modified headstock is used to drive the pipe to rotate, and the cutter fixed on the small carriage is used to cut the pipe. The cutting method of the special pipe cutting machine is: fix the pipe on the bed, and use the cutter to rotate around the outer diameter of the pipe to cut the pipe. The defects of the prior art are: the cutter is frequently damaged; because the steel pipe used for processing and manu...

AI Technical Summary

Problems solved by technology

The defects in the prior art are: the cutting knife is frequently damaged; since the steel pipe used for processing and manufacturing the idler cylinder adopts electric-welded steel pipe, the outer circumference of the electric-welded steel pipe is irregularly convex, and the inner hole of the electric-welded steel pipe is still in the welding process. A raised rib is formed, and the hardness of the periphery of the raised rib is too large. In the process of cutting the roller body, the wear of the cutting tool is accelerated, and the problem of breaking the blade can also occur. In the process of barreling, it is necessary to sharpen and set the knife frequently, and the cutting knife has a width, and some iron filings are formed during the cutting process, resulting in waste of pipes
