Technical Field

[0001] This utility model relates to the technical field of automotive piping, and in particular to a pipe cutting device for piping products. Background Technology

[0002] Piping is the most important component of automotive piping systems. Among them, nylon piping is widely used in automotive piping systems such as thermal management piping, air brake piping, and low-pressure fuel piping due to its strong chemical corrosion resistance and good interface sealing properties.

[0003] During the manufacturing process of pipeline systems, employees need to cut the extruded raw materials into multiple fixed-length pipelines according to the cutting parameters. In the existing technology, double-blade pipe cutters are mainly used to cut the pipelines. When cutting, support allowance needs to be reserved at both ends to avoid the end face being cut at an angle, which results in a high waste.

[0004] With the continuous development of automotive piping systems, nylon tubing is being used more and more widely and the demand is increasing, which puts forward higher requirements for reducing waste during nylon tubing cutting. Utility Model Content
