Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cutting device for producing fireproof and flame-retardant cables. Background Art

[0002] The so-called cable, of course, refers to a rope-like electrical cable that is usually made up of several or several groups of wires twisted together. Each group of wires is insulated from each other and twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. The cable is used to transmit electricity or information from one place to another. Fire-resistant cable is a cable with the advantages of fire resistance, temperature resistance, large current carrying capacity and good flexibility, and is widely used in various fields of life and production.

[0003] However, since most fireproof cables are round, they have a certain curvature after being rolled up, making it difficult to fix them during cutting, resulting in low cutting efficiency, which is not conducive to the production of fireproof cables.

[0004] For example, a fireproof cable cutting device disclosed in Chinese patent CN216989675U, when it is necessary to cut the cable, first place the bent cable on the top of the base, then turn on the motor, and the output shaft of the motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two moving rods to move closer to or away from each other, thereby driving the clamping rod to move through the vertical rod, and clamping the cable through the two clamping rods. The limit plate can improve the convenience of limiting the bent cable during clamping, ensuring that the clamping part is straightened, and then the cutting device cuts the passively straightened cable through the cutting groove position. The structure is reasonable and easy to operate, and can achieve clamping and straightening, which improves the convenience of cutting, thereby improving the cutting efficiency and thus improving the production efficiency.

[0005] However, during use of the device, the worker is required to manually rotate the bidirectional screw rod so that the two moving rods drive the clamping rod to clamp the cable, which is inconvenient to operate and has low clamping efficiency.

[0006] For this reason, we urgently need to provide a cutting device for producing fire-resistant and flame-retardant cables. Utility Model Content
