Description

Technical Field

[0001] The invention relates to the field of mechanical processing, and in particular to a cable processing device. Background Art

[0002] Twisting is an indispensable process in cable processing. With the continuous development and progress of science and technology, the requirements for twisting technology are getting higher and higher. At present, the twisting process is usually achieved by a twisting machine. Monofilaments and strands of different specifications are produced by combining multiple processes of different machine tools. When the twisting machine is working, the driving mechanism drives the incoming wire spindle and the outgoing wire spindle to rotate synchronously, thereby driving the twisting bow to rotate through the twisting bow bracket installed on the incoming wire spindle and the outgoing wire spindle. When the twisting bow rotates one circle, the multiple strands of wire enter from the incoming wire spindle and pass through the first guide wheel to complete one twisting distance, and then pass through the twisting bow to the second guide wheel to complete the second twisting distance. The twisting distance refers to the straight-line distance between the starting and ending points of the steel wire rotating around the strand core or the rope strand rotating around the rope core for one circle when twisting or closing the rope. Existing stranding machines are usually composed of a motor, a transmission device, a main shaft, a main shaft guide wheel, a cradle, a pay-off wheel, a take-up wheel, etc. When the main shaft of this type of equipment rotates one circle, the silk thread is stranded to produce two twist pitches, so it is called a double-pitch stranding machine; currently, most of the stranding machines used for cable production have problems such as the cable is prone to bending or even breaking during processing, which ultimately leads to low cable processing efficiency. Taking the utility model with application number 201821577716.8 as an example, the utility model includes a main shaft, a main shaft pulley, a flywheel, a wire passing wheel and a cradle. The cradle is also provided with a transmission pulley, a gearbox, a multi-groove guide wheel, a balancing guide wheel, a straightening mechanism, a wire taking-up mechanism and a wire arranging mechanism. It adds a wireless metering mechanism to adjust the stranding machine in time when there is a problem with the wire arranging. However, when the wire is working in the wire arranging mechanism, the wire arranging device used in it has a fixed stroke and cannot be adjusted, which makes it impossible to adjust the wire arranging width. It is easy to press the wire when arranging the wire, and the utility model cannot adjust the relative position and wire arranging speed of the wire arranging device, which is prone to problems such as uneven wire release and uneven tension. During processing, the torque fluctuates greatly, and the wire is prone to slippage and premature twisting, causing the processed product to bend or even break. Summary of the invention
