Plastic pipe following copying double-cutting device

Abstract

The invention discloses a plastic pipe following copying double-cutting device and aims at solving the problems that in the producing process of a large-caliber plastic pipe, because large deviations of roundness and ovality exist, a single tool can not cut, an end face is coked, the tool is clamped and broken, and cuttings are sucked to a neck mold by a ventilating device to affect inner wall quality. The plastic pipe following copying double-cutting device comprises a cutting machine rotary disc and a hydraulic controlling and module controlling system and is characterized in that a copying saw blade cutting device and a copying blade cutting device are arranged on the cutting machine rotary disc; copying displacement sensing devices are arranged on the copying saw blade cutting device and the copying blade cutting device correspondingly; and when a cutting signal for a pipe product is obtained, the cutting devices cut the pipe in a following copying mode according to actual outer circle outline signals detected by the copying displacement sensing devices. The plastic pipe following copying double-cutting device achieves equal-thickness cutting in any state, avoids cutting accumulation at the neck mold, and achieves a multifunctional cutting mode.

Description

technical field [0001] The invention relates to the technical field of pipe manufacturing, in particular to a contour-following double-cutting device for plastic pipes. Background technique [0002] In the production process of large-diameter plastic pipes, the roundness and ellipticity of pipe products caused by various factors such as product sagging are very different. Therefore, the final stage of the extrusion molding process is during the cutting process of plastic pipe products. The correct cutting of the product and the quality of the cut surface of the pipe product are important indicators for testing the cutting equipment. Existing cutting equipment generally adopts a single cutting method, so that products with too large ellipse cannot be cut, such as a large-diameter pipe cutting and beveling machine with a patent publication number of CN2762921Y, including a clamping device, a transmission device, a cutting The device, the transmission device and the clamping d...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems caused by large deviations in roundness and ellipticity in the production process of large-diameter plastic pipes, resulting in single-knife inability to cut, coking of the end surface, jamming of the knife and collapse of the knife, and the occurrence of chips being sucked to the position of the die by the ventilation device. To solve the problem of inner wall quality, provide a reasonable structure profiling follow plastic pipe double cutting device
