Wire rope twisting equipment manufacturers believe that the twisting machine, also known as the twisting rope unit, is an important rope forming process in the metal products industry. According to the lay length requirements and rope diameter requirements of different processes, it combines multiple steel wires or aluminum wires into ropes in turn, which is widely used in oil drilling, power transmission, ship lifting and loading, elevator lifting and other industrial and agricultural fields.

Steel wire rope twisting equipment manufacturers believe that the traditional twisting machine consists of a releasing part, a cylinder part, a cradle releasing device part in the cylinder, a cylinder safety cover, a traction part, a twisting part, a reduction gearbox, a ground shaft transmission shaft, a take-up part and an electrical control part. The barrel portion is driven by a belt connected to the main motor. The traditional way to achieve different lay lengths can only be achieved by gradually changing the speed ratio of the gearbox. At the same time, the daily maintenance of the gearbox is relatively large, and a single device can only produce several specifications of fixed rope products.
The production process of wire rope generally goes through several major processes such as wire drawing, twisting, twisting, and winding, as follows:
Wire drawing: Wire rope twisting equipment manufacturers believe that wire drawing in wire rope production refers to the process of wire rod involving pickling, phosphating, shelling, cutting blanks, etc. In this process, one or more drawing processes will be carried out to change the internal molecular structure of the raw material to achieve the required target diameter. In the wire drawing process, the main equipment is the water tank wire drawing machine or the straight wire drawing machine. The raw materials are generally ferrous metals with a diameter of 0.14-10mm and non-ferrous metals with a diameter of 0.01-16.00mm.
Pickling of straight wire drawing machine is a process of washing rust and peeling on the surface of wire rope raw materials with acid solution, also known as peeling, mainly to remove surface oxides to prevent rust or other impurities from affecting the quality of billets and damaging wire drawing abrasives.
Wire rope twisting equipment manufacturers believe that phosphating is a process in which materials invade the phosphating solution and form a layer of water-insoluble phosphating solution film on the surface of the material after reaction, which has a certain anti-corrosion effect.
The open blank is the forming hole that forces the metal through the grinding tool, and its size and shape will change. The die holes for drawing the wire are circular, square, octagonal or other special shapes.
Wire rope twisting equipment manufacturers believe that cold wire drawing is to forcibly pull ordinary round steel through a hole smaller than its diameter, and the diameter of round steel will become smaller. According to the equal volume change ratio, the length will also be longer. Repeatedly repeat this process, the diameter of the round steel will be further reduced. However, after this plastic deformation, the hardness of the steel will increase, and its plasticity will basically disappear, so this steel can be used in occasions that require only strength and not plasticity.
Steel wire rope twisting equipment manufacturers believe that tempering refers to the fact that the internal molecular structure of the steel wire has been destroyed, and only through tempering can the internal molecular structure of the steel wire be reduced again, thus facilitating the drawing again, making it difficult to break and achieving the required strength. Simply put, strength is what we usually call tensile strength. The strength is drawn, not heat-treated, which is also the main difference between the wire rope manufacturing process and the machining process.
