Description

Technical Field

[0001] The invention relates to the technical field of cable stranding, in particular to an automatic stranding device and a stranding method for producing electric wires and cables. Background Art

[0002] Stranded wire is made by twisting single wires around the strand axis at equal angular velocity and moving the strands forward at a uniform speed. Copper and aluminum are commonly used. Copper and aluminum wires can be twisted into conductor cores of various specifications and cross-sections as well as different types of wires and cables. They are suitable for situations where the operating frequency is high and the skin effect and proximity effect losses of single-strand wires are too large. The use of stranded wire can reduce the operating temperature. Compared with single-strand wires of the same cross-sectional area, stranded wires have higher mechanical properties and flexibility.

[0003] According to Chinese patent publication number CN113990583B, in order to solve the problem that the existing stranded wire processing device can only adapt to the processing process of wires with one number of strands, and the rotation speed is difficult to adjust due to the different numbers of strands of the wires, the following solution is proposed, which includes a control box and two symmetrically arranged fixed plates, the two fixed plates are arranged on one side of the control box, and a winding assembly for winding the stranded wire is arranged between the two fixed plates, and a round rod is rotatably penetrated on one side of the control box.

[0004] At present, the existing automated stranding devices for producing wires and cables and the above-mentioned cases are unable to perform efficient disc stranding work. At the same time, after the stranding is completed, internal extrusion processing cannot be performed to reduce the contact gap and affect the subsequent winding. Therefore, improvements are made to the above-mentioned problems. Summary of the invention
