Novel plastic pipe cutting machine

Abstract

The invention relates to a novel plastic pipe cutting machine, which comprises a working table. A rotary shaft, a rotary motor and a clamping sleeve are arranged on the upper part of the working table; one end of the rotary shaft is connected with a cutting sleeve pipe; the cutting sleeve pipe is a tubular shell with one sealed end; and the center of the sealed end of the cutting sleeve pipe is connected with the end part of the rotary shaft. According to the novel plastic pipe cutting machine provided by the invention, a cutter is utilized for circumferentially cutting a macromolecule pipe, so that compared with saw blade cutting, a cutting surface of the macromolecule pipe cut by using the cutter is smoother, and the occurrence of the phenomenon of excessive coarseness is avoided. With an inclined surface of a taper sleeve, horizontal sliding of the taper sleeve is converted into up-and-down movement of a movable sliding block, so that the sufficient pressure can exist between the cutter and the macromolecule pipe, and the cutter can conveniently cut the macromolecule pipe.

Description

technical field [0001] The invention relates to a pipe cutting machine, more precisely a novel plastic pipe cutting machine. Background technique [0002] In recent years, ultra-high polymer materials have been widely used. Due to technical reasons, ultra-high polymer materials cannot be injection-molded with high efficiency. They can only be processed into profiles of various shapes and cross-sections by extruders through high-temperature and high-pressure extrusion, and then processed by machine tools. To meet the needs of use, the application of pipe profiles is very extensive. Pipes are processed into various types of workpieces by using various machine tools in mechanical processing. Production efficiency, the production process mostly uses disc welded toothed saw blades or band saws for high-speed cutting in the initial blanking stage. The cutting surface is rough, the crack is large, and the verticality is poor. In order to meet the finishing process, a large enough s...

Production efficiency, the production process mostly uses disc welded toothed saw blades or band saws for high-speed cutting in the initial blanking stage. The cutting surface is rough, the crack is large, and the verticality is poor. In order to meet the finishing process, a large enough space must be left. machining allowance, which creates unnecessary waste in the initial roughing

The existing rotary-knife cutting machine tools have high processing efficiency for metal pipes, but when processing polymer materials, the cutting efficiency is extremely high due to many reasons such as the high toughness of the polymer pipe, the large clamping deformation, and the small friction coefficient of the polymer surface. low, can't even cut
