Thin-wall pipe cutting device

Abstract

The invention discloses a thin-wall pipe cutting device. The thin-wall pipe cutting device comprises a rotating fixing machine and a cutting machine, wherein the cutting machine comprises a first gyring blade and a second gyring blade; the first gyring blade extends into a thin-wall pipe, and the second gyring blade is arranged at the outer side of the thin-wall pipe; the first gyring blade and the second gyring blade are matched to cut the thin-wall pipe. According to the thin-wall pipe cutting device, the two gyring blades are provided; one gyring blade extends into the thin-wall pipe, and another gyring blade is arranged at the outer side of the thin-wall pipe; the two blades are adjusted to be tangential to each other during the cutting process and can synchronously extrude the thin-wall pipe from the inside and the outside so as to enable uniform internal and external stressing, and as a result, a port formed by cutting is flat, and the circumstance that the thin-wall pipe is broken can be avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to thin-walled pipe cutting equipment. Background technique [0002] During the cutting process of the thin-walled tube (with a wall thickness of 0.3-0.6mm), the cutting blade is set on the outside of the thin-walled tube. During the cutting process, the thin-walled tube rotates, and the cutting blade squeezes the thin-walled tube. Press to complete the cutting work of thin-walled tubes. In this cutting process, because the extrusion force of the cutting blade on the thin-walled tube is concentrated at one point, and the tube wall of the thin-walled tube is relatively thin, the wall of the thin-walled tube often tears during the cutting process, resulting in uneven cutting It is flat, and the cutting edge needs to be trimmed before it can be used, which not only causes waste of raw materials, but also reduces production efficiency.
