Description

Technical Field

[0001] The utility model belongs to the technical field of HDPE corrugated pipe cutting, and specifically relates to a HDPE corrugated pipe cutting device. Background Art

[0002] HDPE corrugated pipe is a new type of lightweight pipe made of high-density polyethylene, which has the characteristics of light weight and high pressure resistance. During the production and processing of corrugated pipes, it is necessary to cut them to reduce the length for easy loading, unloading and transportation.

[0003] In the prior art, a corrugated pipe cutting device is generally used to cut the corrugated pipe. For example, the invention with patent publication number CN113211508A discloses a HDPE double-wall corrugated pipe cutting processing equipment and a cutting processing method. The HDPE double-wall corrugated pipe cutting processing equipment includes a support seat, a fixing unit and a cutting unit. The support seat is symmetrically provided with mounting grooves, and the mounting grooves are symmetrically provided with convex slide grooves. The fixing units are symmetrically installed on both sides of the upper end of the support seat, and the cutting unit is arranged at the center of the upper end of the support seat, wherein the cutting unit includes a positioning cylinder, a supporting column, a transmission motor, A support shaft, a linkage rod and a cutting saw blade, wherein: a positioning cylinder is symmetrically installed at the upper end of a support seat through a fixed groove, the end of the telescopic rod of the positioning cylinder is connected to a supporting column, a cylindrical groove is opened inside the supporting column, and sliding grooves are opened at equal intervals from front to back at the lower end of the cylindrical groove, a transmission motor is installed at the front end of the supporting column through a motor seat, and a support shaft rotatably arranged in the cylindrical groove is installed on the output shaft of the transmission motor, linkage grooves corresponding to the sliding grooves are opened at equal intervals on the outer side wall of the support shaft, one end of the linkage rod is slidably arranged in the linkage groove, and the other end is slidably arranged in the sliding groove, and a cutting saw blade is arranged at the lower end of the linkage rod.

[0004] The above-mentioned cutting processing equipment reciprocates the cutting of the corrugated pipe by a cutting saw blade to ensure the flatness of the cut. However, the cutting by the cutting saw blade will cause burrs to be generated at the cut of the corrugated pipe. Although the cutting processing equipment is also provided with a grinding belt to grind the burrs at the cut of the corrugated pipe, this undoubtedly increases the processing steps of the corrugated pipe cutting, prolongs the cutting time of the corrugated pipe, and reduces the cutting efficiency.

During the cutting process, as the incision of the corrugated tube becomes thinner, the spring 27 pushes the telescopic rod 26 to extend, so that the disc blade 23 moves forward, deepens the cutting of the incision by the disc blade 23, speeds up the cutting speed, and improves the cutting efficiency.
