A kind of over-axis structure of bow twisting machine

Abstract

The utility model discloses an over-axis structure of a bow twisting machine, which belongs to the technical field of cable twisting. The main points of the technical scheme include a front bottom plate, a rear bottom plate and a main shaft. The rear bottom plate is arranged on the right side of the front bottom plate, and the left side of the top of the front bottom plate and the left side of the top of the rear bottom plate are both provided with bearing seats. By arranging the front bottom plate and the rear bottom plate, when performing the twisting action, the cable is first passed through the front bottom plate, and bypasses the wire drum along the rear twisting bow, and enters from the top of the wire drum on the left side inside the bearing seat, passes out from the bottom, and then passes backwards along the bow frame on the front side of the rear bottom plate, and always maintains S-shaped transmission. Another strand of cable on the wire drum enters from the right side of the bottom of the wire drum in the bearing seat, passes out from the top and bypasses the rear wire drum along the rear bow frame. This method allows the cable to directly pass through the wire drum to pass the cable shaft, and avoids the poor tensioning effect caused by multiple changes of direction.

Description

Technical Field

[0001] The utility model relates to the technical field of cable stranding, in particular to an over-axis structure of a bow stranding machine. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. In order to ensure its strength, most of them are made by twisting multiple wires together. The twisted wire is achieved by twisting the single wires around the twist axis at an equal angular velocity and moving the twisted wire 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 and 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 twisted wires can reduce the operating temperature. Compared with single-strand wires with the same cross-sectional area, twisted wires have higher mechanical properties and flexibility.

[0003] The existing bow twister structure requires the cable to miss the main shaft structure many times when twisting the steel cable structure, and needs to be rotated and guided by the guide wheel many times to bypass the main shaft when avoiding the main shaft. This is not only troublesome, but also easy to get loose. The multiple changes in direction of the cable may cause the tensioning effect to weaken, which may affect the performance of the finished cable. Utility Model Content
