Embodiment 1

[0033] As embodiment 1 of the present invention: a kind of production method of bending resistance high flexible towline cable, comprises the following steps:

[0034] The first step is to extrude the wire core raw material in the first extruder, add the water blocking paste raw material into the barrel of the water blocking paste machine and mix it. After the raw material is mixed, it will stick to the water blocking paste machine guide wheel to block water Paste, and make the wire core 1 and nylon wire 4 coated with the core layer 2 pass through the die head of the water blocking paste machine, and then adhere the water blocking paste to the guide wheel of the water blocking paste machine to realize the water blocking of the wire core 1 processing, and forming a water blocking layer 3;

[0035] In the second step, the water-blocking processed cables are input into the second extruder, and rubber is filled on the extruder, and the rubber is extruded to form a protective inner...

Embodiment 2

[0042] As embodiment 2 of the present invention: a kind of production method of bending resistance high flexible towline cable, comprises the following steps:

Abstract

The invention belongs to the field of cables, particularly relates to a bending-resistant high-flexibility drag chain cable and a production method thereof, and solves the problems that the existing drag chain cable is poor in bending resistance, poor in wear resistance and not high enough in strength, wrinkles are extruded during production, and cracks exist on the surface of a protective outer layer after the drag chain cable is cooled. The bending-resistant high-flexibility drag chain cable comprises a wire core, wherein the outer side of the wire core is coated with a core-spun layer, theouter side of the core-spun layer is provided with a water-blocking layer, a nylon wire is arranged in the water-blocking layer, the outer side of the water-blocking layer is provided with a protective inner layer, the outer side of the protective inner layer is provided with a reinforcing layer, and the outer side of the reinforcing layer is provided with a protective outer layer. According to the invention, the annular groove is designed in the surface of the protective outer layer, and the protective outer layer is extruded by the wear-resistant rubber, so that the bending resistance and the wear resistance of the cable can be good; and the structural strength and the pulling resistance of the cable can be high by designing the reinforcing layer woven by the aramid fiber wires and adding the nylon wire into the water-blocking paste.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a bending-resistant and highly flexible drag chain cable and a production method thereof. Background technique [0002] Drag chain cables are often used in mobile mechanisms. Due to special working conditions, drag chain cables will be pulled frequently during use, which requires that the drag chain cables have sufficient flexibility. In the occasion where the equipment unit needs to move back and forth, in order to prevent the cables from being entangled, worn, pulled off, and hung loosely, the cables are often put into the cable drag chain to protect the cables, and the cables can also move back and forth with the drag chain. The highly flexible special cable that can move back and forth with the tow chain and is not easy to wear is called a tow chain cable, usually also called a tow cable, tank chain cable. [0003] However, the existing towline cables have poor bending resist...
