[0002] At present, the self-supporting cable is used as a driving electric hoist connection and control cable, which is suitable for various electrical installations in dry or humid indoors; given its special flexible design, it is also suitable for non-stress slow release can be forced to guide the left and right non-continuous Installation or fixed laying under sexual movement, but the existing self-supporting cables cannot meet the requirements at low temperatures. When the cables are separated at low temperatures, it is easy to tear the main cable, resulting in reduced shielding effects, etc.

The invention discloses a self-supporting cable manufacturing mold and a manufacturing process, comprising a cable punch and a cable die, the cable die is provided with a punch cavity, and one end surface of the cable die is provided with a main outlet hole , the side of the main outlet is provided with a secondary outlet, a passage is arranged between the main outlet and the secondary outlet, the passage is connected to the main outlet and the secondary outlet, and the passage is close to the secondary outlet. Chamfering is provided at the end of the hole. In the present invention, on the passage between the main outlet hole and the secondary outlet hole of the self-supporting cable manufacturing mold, a chamfer is arranged near the end of the secondary outlet hole, so that a tearing weak point is formed on the connecting rib of the suspension wire and the main wire, and the When it is torn, it will be torn along the weak point, which plays a guiding role, thus ensuring that the sheath of the main line will not be torn and there will be no tear dents.
Description
technical field [0001] The invention relates to the field of cable production, more specifically, the invention relates to a self-supporting cable manufacturing mold and a manufacturing process. Background technique [0002] At present, the self-supporting cable is used as a driving electric hoist connection and control cable, which is suitable for various electrical installations in dry or humid indoors; given its special flexible design, it is also suitable for non-stress slow release can be forced to guide the left and right non-continuous Installation or fixed laying under sexual movement, but the existing self-supporting cables cannot meet the requirements at low temperatures. When the cables are separated at low temperatures, it is easy to tear the main cable, resulting in reduced shielding effects. Contents of the invention [0003] The purpose of the present invention is to solve the existing above-mentioned problems and provide a self-supporting cable manufacturin...
