The steel wire rope twisting equipment is a process of twisting steel wires according to technical requirements around the centerline of the rope strands in a regular spiral arrangement, and is one of the important processes in steel wire rope production. The structure of a stock is different, and the diameter, number, and arrangement of steel wires inside the stock are also different. The number of steel wires arranged outside the stock is also different. Generally speaking, one, two, three, or even more layers of steel wire can be arranged outside the core. According to its cross-sectional shape, strand lines can be divided into circular strand lines and irregular strand lines. The twisting of the strand can be carried out using tube twisting machines, basket twisting machines, and tubeless twisting machines.

What is the twisting principle of wire rope twisting equipment? Let's take a brief look together.

Twisting should be carried out according to the technical requirements of the steel wire rope. The twisting direction, twist distance, strand diameter, core diameter, and the diameter, tensile strength, toughness value, coating quality, and length of the twisted steel wire should meet the specified requirements. On this basis, select and prepare steel wire rope, I-shaped wheel diameter, branch drum, lay pitch cone, deformer, and wire pressing tile. The selection of the twisting machine should also be carefully carried out to improve the twisting efficiency.

The steel wire rope twisting equipment installs the I-shaped wheel of the rewinding steel wire on the I-shaped wheel frame of the stranding machine and locks it, so that the end of each steel wire passes through the threading hole of the stranding machine. The distribution of the threading holes of the stranding machine should be adapted to the stranding structure and pass through the wire pressing tile. The steel wire ends are assembled into bundles and connected to the traction wheel lead. Select the lay length cone according to the lay length requirements, adjust the tightness of each steel wire, and ensure the tension of the steel wire during the twisting process. Adjust the position of the pressing shoe to make it tight, and then adjust the parameters of the deformer. After adjustment, slowly start the car. When the twist distance and diameter of the steel strand meet the requirements, it can be twisted normally. The traction wheel of the stranded wire should be wound with a certain number of turns, usually 5-6 turns, to ensure that the stranded wire pulled out by the wire pressing tile has a certain tension. The twisted wire is wound on the winding wheel by the winding device through the wire arrangement device, and the length of the rope strand is displayed by the counter.

The twisting of each layer of steel wire in the point contact steel strand should be carried out separately. When selecting a twisting machine, the number of I-shaped wheels must be greater than or equal to the number of steel wires in that layer. For example, a wire strand with a structure (1+6+12+18) is twisted three times on a twisting machine with 6 I-shaped wheels, 12 I-shaped wheels, and 18 I-shaped wheels, respectively. The contact wire rope strand is twisted in one go, and all the steel wires (two or three layers) that make up the strand are twisted in one go on the same machine. Therefore, a multi I-shaped wheel twisting machine is generally used for twisting wire contact strands. For example, the (1+7+7/7+14) structure is twisted by a twisting machine with 36 I-shaped wheels, and the twisting of point strands is divided into two layers on two twisting machines, such as (1+6)+12+12 strands, (1+6) is twisted on a 6-shaped wheel twisting machine, and the other two layers are twisted on a 24 shaped wheel twisting machine. The twisting of special-shaped steel wire ropes and steel wire rope strands is carried out on specialized equipment.
