Description

Technical Field

[0001] The invention belongs to the technical field of cable processing equipment, and in particular relates to a ring cutting device and a ring cutting method for power cable processing. Background Art

[0002] Cable is an electrical wire that transmits electrical energy or signals and is composed of conductors, insulation layers, sheaths, etc. It is usually used to connect different electrical equipment, transmit power or signals, and protect lines. According to the purpose and characteristics of the cable, it can be divided into many types, such as power cables, communication cables, control cables, etc. Cable ring cutting refers to cutting or stripping the outer insulation layer of the cable for wiring or maintenance. Especially when making cable heads, the cable sheath, steel armor, filling layer, shielding layer and insulation layer must be stripped one by one. Traditional cable stripping tools are manual stripping by workers using tools such as electrician knives, hook knives or wallpaper knives. However, these ring cutting tools generally have insufficient clamping stability or large deviations in fixed axis accuracy. They are easy to shake when cutting the cable skin, and the depth of the cable skin is uneven. Especially when cutting the semi-conductive layer or copper shielding layer of the cable, it is easy to penetrate the semi-conductive layer or copper shielding layer during cutting and destroy its internal structure, and there are certain safety hazards.
