Rotary copying cutter of plastic corrugated pipe cutting machine

Abstract

The invention discloses a rotary copying cutter of a plastic corrugated pipe cutting machine. The rotary copying cutter comprises a cutting blade and a fixed cutter frame; and the cutting blade includes a cutter tip end and a shank end. The cutting blade is arranged in the fixed cutter frame; the length of the cutting blade for extending out from the fixed cutter frame is within 1.1-1.5 times of the thickness of a pipe; the bottom of the fixed cutter frame takes the shape of a corrugated tooth; the thickness of the bottom of the fixed cutter frame is within 1.1-1.2 times of the thickness of the corrugated bottom surface of the pipe; and an included angle between the side surface of the corrugated tooth of the bottom of the fixed cutter frame and the axis of the pipe is a sum of a dip angle of the corrugation of the pipe and 1-5 degrees. The fixed cutter frame can extend into the corrugation of the pipe during cutting; and when the corrugated pipe is cut, the cutter is bound without deflecting to two sides, so that the end surface of the cut corrugated pipe is tidy without deviation.

Description

technical field [0001] The invention relates to a line cutting machine for plastic pipe production, in particular to a rotary profiling cutter for plastic corrugated pipes. Background technique [0002] The current plastic pipe cutting machine often adopts a chip-free cutting method, and the cutting of the pipe is completed by rotating the cutting blade on the surface of the pipe. In order to reduce the resistance and debris generated by the cutting blade in the plastic pipe cutting machine, the cutting edge of the cutting blade is generally thinner, and the cutting blade needs to be replaced frequently due to the wear of the cutting blade during the cutting process. In order to reduce the waste of blade material, the tail of the cutting blade should not be too thick, so generally the cutting blade needs to be installed on the knife block before it can be installed on the knife seat. like figure 1 As shown, in the traditional cutting machine, the long cutting blade 2 is fi...

AI Technical Summary

Problems solved by technology

Because the pipe is hot, there is a certain deformation, the cutting length of the knife is too long during the cutting process, it is easy to bend and deform, it will deviate from the left and right, it is easy to cut into a jagged shape or cut to the peak, the pipe will be cut, and then waste products will be generated
