Description

Technical Field

[0001] The utility model relates to the technical field of strand twisting machines, in particular to a horizontal inward-retracting and outward-releasing four-fold strand twisting machine. Background Art

[0002] The stranding machine is also called the stranding rope unit. It is the post-rope making process in the metal products industry. It combines multiple steel wires or aluminum wires into a rope in an orderly manner according to the twisting pitch requirements and rope diameter requirements of different processes. It is widely used in industrial and agricultural applications such as oil drilling, power transmission, ship lifting and unloading, elevator lifting, etc. The stranding machine consists of the main parts such as the transmission device, the twisting machine body, the wire pressing shoe device, the traction device, the safety and parking device, the wire collection and arrangement device, and a series of auxiliary machines such as cranes, welding machines, and cutting machines. The stranding machine usually refers to its main part without including the auxiliary machines. Machinery, stranding machines are of several types according to the machine body structure type, such as basket type, tube type and tubeless type; in the prior art, stranding machines are mostly horizontal stranding machines. When stranding, the high-speed rotation of the cylinder cooperates with the linear traction generated by the traction device, so that the steel wire produces helical winding and linear motion of the strand, forming a strand with a certain twist distance, thereby completing the basic twisting action of the strand, but some horizontal stranding machines can only strand the steel wire once at a time. In the production process of some high-quality wire ropes, the steel wire needs to be stranded multiple times, and the twisting time required is relatively long, which affects the twisting efficiency of the horizontal stranding machine.
