Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a serpentine hose cutting machine. Background Art

[0002] Serpentine hose is also often called flexible hose, corrugated hose or bent hose. It is a highly flexible and bendable pipe, usually made of rubber or plastic. There is a series of continuous corrugations or spiral structures on the serpentine hose body. This structure gives the hose the ability to bend easily without damage. It is particularly suitable for occasions that require flexible connection or wiring and piping in limited space. It is mainly used for liquid or gas transmission between various equipment, such as refrigerant pipes in air-conditioning systems, engine cooling systems, hydraulic system oil pipes, etc. It can also be used as a protective casing for wires and cables, or as an inlet and outlet pipe for washing machines, etc.

[0003] After being produced, serpentine hoses are all whole long tubes. They need to be cut into multiple hoses of specific lengths according to customer requirements. The traditional manual cutting method using hand tools is not only inefficient, but also has poor precision and cannot meet production requirements. General cutting machines only have simple feeding and cutting, and lack the necessary locking device during the cutting operation. The feeding and cutting parts do not work well together, and can only cut one serpentine hose at a time. One device can only cut one type of serpentine hose, which is inefficient.
