Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a cutting device which is convenient for adjusting the spacing and is used in the production of flame-retardant cables. Background Art

[0002] Flame-retardant cable refers to a cable that, under specified test conditions, the sample is burned. After the test fire source is removed, the spread of the flame is limited to a limited range, and the residual flame or residual burning can extinguish itself within a limited time. The fundamental characteristic is that it may be burned and unable to operate in the event of a fire, but the spread of the fire can be prevented. In layman's terms, if a fire occurs in the wire, the burning can be limited to a local range, and the spread can not occur, so as to protect various other equipment and avoid causing greater losses. In the production process, it is necessary to cut the flame-retardant cable. The existing flame-retardant cable cutting device is generally used to cut vertically up and down the flame-retardant cable when in use. During cutting, the middle position of the flame-retardant cable is prone to deformation, and in order to improve the cutting accuracy, fine-tuning is required after the cable is placed. For flame-retardant cables with larger diameters, their weight is also heavier, and fine-tuning is more difficult. Therefore, a cutting device that is convenient for multi-point circumferential rotation cutting of flame-retardant cables is designed to reduce the deformation at the cutting position, and at the same time facilitates fine-tuning of the spacing during cutting preparation, so as to further improve the cutting accuracy of flame-retardant cables.
