Anti-deformation cutting device for thin-wall steel pipe

Abstract

The invention provides an anti-deformation cutting device for a thin-wall steel pipe, and relates to the field of metal material machining. The anti-deformation cutting device for the thin-wall steel pipe comprises a supporting plate and a motor, wherein the motor is fixedly installed at the side of the supporting plate; a power mechanism is fixedly installed on the side face of the supporting plate; the outer surface of the power mechanism is sleeved with a rotating mechanism; the outer surface of the rotating mechanism is sleeved with a supporting sleeve; the supporting sleeve is fixedly connected with the supporting plate; and the front end of the rotating mechanism is in threaded connection with a cutting mechanism. According to the anti-deformation cutting device for the thin-wall steel pipe, under the transmission of a ratchet sleeve and an inserting stick, a threaded sleeve is matched to drive a connecting rod to rotate and move, so that a boss block extrudes a cutter to enable the cutter to extend towards the outer side and rotate, the thin-wall steel pipe can be cut from the interior, the position of a cutting point of the thin-wall steel pipe and the stress direction of the cutting point can be changed, an outer hoop sleeve is matched for supporting, and finally, the problem of deformation of the thin-wall steel pipe in the cutting process can be avoided.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to an anti-deformation cutting device for thin-walled steel pipes. Background technique [0002] A steel pipe whose outer diameter to wall thickness ratio is greater than that is called a thin-walled steel pipe. Thin-walled steel pipes Thin-walled steel pipes are made by cold drawing. Among them, carbon steel, low alloy steel, and alloy steel thin-walled pipes are suitable for general structures and mechanical structural parts; thin-walled fluid steel pipes are used for conveying general fluids; stainless steel thin-walled pipes are used for chemical industry, petroleum, light industry, food, mechanical instruments, etc. Industrial heat-resistant containers, conveying pipes and mechanical structural parts.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, during the cutting process of the thin-walled steel pipe, the cutting device needs to apply a radial force to the thin-walled steel pipe. This force can make the cutting mechanism contact the thin-walled steel pipe, but at the same time, this force can squeeze the thin-walled steel pipe to deform.
