Cutting-off and chamfering integrated turning tool and one-step clamping, cutting-off and chamfering pipe cutter

Abstract

The invention relates to a cutting-off and chamfering integrated turning tool and a one-step clamping, cutting-off and chamfering pipe cutter and belongs to pipe machining equipment. A main cutting edge is arranged on a front tool surface of the front of a tool handle, and two V-shaped grooves are symmetrically arranged in two auxiliary cutting edges, so that both cutting-off and chamfering can be performed, the operation is flexible, and exchanging of different turning tools during chamfering are avoided. The cutting-off and chamfering integrated turning tool is used by the pipe cutter, a thrust bearing, a tapered wedge thrust pipe and a plurality of tapered wedge pipes which are mounted on a cylindrical shaft successively are connected together, and a rotary feed pipe is clamped firmly by outward expansion of C-shaped rings under thrust of a clamping air cylinder piston and tapered heads. By means of the cutting-off and chamfering integrated turning tool mounted on a sliding shaft lathe tool rest, within the range of clearance grooves of the tapered wedge pipes, during feed pipe cutting-off tool withdrawn, and on a device, during once clamp of the inner diameter of a thin-wall round pipe, a plurality of feed pipes can be cut off by setting the length, and chamfering is performed on inner and outer edges of two end faces of notches.

Description

technical field [0001] The invention relates to a cutting and chamfering integrated turning tool for cutting thin-walled round pipes and a pipe cutting machine for cutting and chamfering at the same time in one clamping. A turning tool for chamfering the inner and outer edges of both ends, and a pipe cutting machine using this turning tool. Background technique [0002] In industrial production, after the thin-walled round tube is cut, it is also required to chamfer the inner and outer edges of the two ends of the cut. At the same time, it is also required that the roundness accuracy of the material tube should not be damaged during the process of clamping the round tube. At present, the traditional tube cutting Processing mainly has the following four processing methods. [0003] 1. Lathe cutting and chamfering processing method: [0004] The outer diameter or inner diameter of the round pipe is clamped by the chuck of the lathe. When the pipe wall is about to be cut off,...

AI Technical Summary

Problems solved by technology

[0010] The noise pollutes the environment, the conical knife can only invert the inner corner of the end face of the pipe, and the outer corner cannot be inverted, and the chamfering of the file is labor-intensive, low in efficiency, and poor in quality.

[0011] The above four cutting and chamfering processing methods have one thing in common. In the mechanical clamping and fixing of the outer diameter of the thin-walled tube, not only the roundness and cylindricity accuracy of the round tube will be changed, but also the potential impact will be caused. The next process is based on the inner diameter of the material tube and the improvement of processing accuracy

[0012] The patent number is 201210264520.4, and the invention title is "differential pipe cutting machine for internal and external chamfering of both ends of the incision at the same time", which solves the problem of internal and external chamfering of both ends of the incision after the round tube is cut
