Technical Field

[0001] The present invention relates to the technical field of copper tube cutting, and in particular to an automatic copper tube water jet cutting device and a copper tube water jet cutting process. Background Art

[0002] Copper tubes are also called red copper tubes. They have good electrical and thermal conductivity and are the main materials for conductive and heat dissipation accessories of electronic products. The basic production process of copper tubes includes smelting, washing, coiling, forming and packaging. In the process of each process, equipment for cutting copper tubes is often used.

[0003] In traditional technology, for the cutting of large diameter pipes, pipe cutting machines are generally used for cutting. Since the diameter of copper pipes is small, pipe cutting machines cannot be used for cutting small diameter copper pipes due to clamping and cutting problems. Therefore, for copper pipes with smaller diameters, workers generally operate saw blade cutting machines for cutting. When cutting, workers press down the saw blade cutting machine, and the saw blade cutting machine cuts the copper pipe from one side.

[0004] With the development of modern science and technology, the production of various products has put forward higher requirements for copper tubes. The products processed by traditional cutting technology have complicated subsequent processing technology, uneven strength caused by lattice changes, and complex physical and chemical properties at the cut point, which cannot meet the needs of more lean processing.
