Spiral pipe cutting machine

Abstract

The invention provides a spiral pipe cutting machine. The spiral pipe cutting machine is used for cutting a pipe, comprises a rack and is characterized in that the rack is provided with a cutting table capable of horizontally moving along the rack; along the moving direction of a pipe to be cut, at least one of both the front and rear ends of the cutting table is provided with a pressing mechanism for pressing the pipe to be cut; the pressing mechanism comprises at least three rollers which are arranged along the peripheral wall of the pipe to be cut and are abutted against the peripheral wall of the pipe to be cut to press the pipe to be cut; and the middle of the cutting table is provided with a cutting mechanism for cutting the pipe to be cut. According to the spiral pipe cutting machine provided by the invention, by the roller, the rotation of the pipe is not blocked when the pipe to be cut is clamped, so that the cutting on the pipe can be efficiently completed. The spiral pipe cutting machine provided by the invention can be implemented by simple transformation on the basis of an original cutting machine and has the advantages of low cost, good cutting effect, simplicity of operation and the like.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a cutting machine for cutting pipes with helical patterns inside. Background technique [0002] Due to their excellent physical and chemical properties, pipes such as PVC and PE pipes are more and more widely used in construction, water supply and drainage and other fields. When this kind of pipe is actually used, the liquid flow rate is too fast, and it will collide with the pipe wall, which will make a lot of noise. In order to solve this problem, a spiral protruding rib is usually set in the pipe wall, also known as the spiral pattern; after the spiral pattern is formed, the liquid in the pipe will flow spirally along the thread pattern, so that it will cling to the pipe under the action of centrifugal force. wall, so as to avoid hitting the pipe wall to make noise. When producing such spiral-shaped PVC and PE pipes, during the extrusion molding process through the injection molding mach...

AI Technical Summary

Problems solved by technology

When cutting the pipe, the currently commonly used cutting machine without spiral pattern cannot be used: because the cutting machine must clamp the pipe before cutting, and move horizontally with the pipe synchronously to cut; while the pipe is still Rotating around its own axis, the cutting tool cannot follow the rotation of the pipe, so the cutting work cannot be completed
