Description

Technical Field

[0001] The utility model relates to the field of corrugated pipe cutting, in particular to a plastic corrugated pipe cutting machine. Background Art

[0002] As a pipe connection device, the hardness and softness of a corrugated pipe usually refer to the hardness and softness of the corrugated pipe when it is not under force. It has both the flexibility and toughness of a part of a flexible pipe and the pressure resistance and stability of a part of a rigid pipe. Due to the special structure of the corrugated pipe, the quality of the internal metal pipe determines the stiffness and strength of the corrugated pipe. Generally, the corrugated pipe can withstand a certain degree of bending and will not quickly return to its state before bending, so it can be regarded as a flexible pipe.

[0003] After retrieval, the Chinese patent publication number: CN218802530U discloses a plastic corrugated pipe cutting machine. The output end of the hydraulic push rod can drive the moving component to move longitudinally in the machine cover, and the moving component can drive the deflection frame to deflect at the hanging ear and change the position of the pressure roller, so that when the cutting knife moves downward for cutting, the corrugated pipe can be simultaneously pressed tightly, and the pressing and cutting of the corrugated pipe can be carried out simultaneously.

[0004] In the above technical solution, the hydraulic push rod and the moving component are used to provide pressing force for the corrugated pipe during cutting. However, some corrugated pipe materials are relatively soft. After being pressed tightly, the corrugated pipe will be in a compressed deformation state under the action of force. After cutting, the staff needs to manually restore the deformation, which increases the subsequent processing procedures of the corrugated pipe and reduces the cutting efficiency of the corrugated pipe. Therefore, a plastic corrugated pipe cutting machine is proposed to solve the above problems. Summary of the Utility Model
