Description

A bow twisting machine convenient for adjusting the tension of the wire

Technical Field

The utility model relates to the technical field of bow twisters, in particular to a bow twister which is convenient for adjusting the tension of the wire release.

Background Art

Bow twister is a kind of stranding machine. In the process of cable manufacturing, a stranding machine is needed to twist the wire harness. In the production, many wire cores are twisted together to make multi-core cable, which can reduce the total volume of the cable, reduce the space occupied by the cable, reduce the amount of material used, and reduce production costs. The cable bow twister has both the rotational motion of the insulated wire core around the central axis and the horizontal linear motion of the cable core along the axis. The rotational motion is generated by the rotation of the auger, and the horizontal linear motion is generated by the traction device. The auger completes one twisting for each rotation. At the same time, the distance traveled by the traction is a pitch length. In this way, by changing the coordination of the two movement speeds, the size of the pitch (or helix angle) can be adjusted to produce a cable with a cable core.

The existing publication number CN207165303U discloses a new type of cable bow twisting machine, including a base, and a motor, a pay-off unit, a support and a ground shaft installed on the base. A plurality of pay-off units are connected in series in sequence, and each pay-off unit comprises a pay-off wheel, a cradle and a bow belt. A central tube is fixed at both ends of the bow belt, and each central tube is rotatably supported on a support. The two ends of the cradle are rotatably connected to the end of the central tube, and the two ends of the pay-off wheel are rotatably connected to the cradle. The axial direction of the pay-off wheel is perpendicular to the axial direction of the central tube, and a cavity is formed in the axial direction of the central tube. A through hole connected to the cavity is opened on the side wall of the central tube. The wires between adjacent bow belts are passed through the through hole and the cavity through a guide wheel. The motor acts on the ground shaft and can drive it to rotate. The ground shaft and the central tube are transmission-connected. The wires between adjacent pay-off units of the new type are routed through the inside of the rotatable central tube. On the one hand, it provides safety protection for the wires, and on the other hand, the wires occupy little space.

During use of the existing bow twisting machine, the wire harness is passed through the twisting bow, and the curvature of the twisting bow is not easy to adjust, which is not conducive to adjusting the tension of the wire harness. As a result, during the twisting process, the quality of the cable twisting is poor, the tightness is not good, and the wire harness tension cannot be adjusted according to the actual situation of the twisting.

Therefore, those skilled in the art provide a bow-twisting machine that is convenient for adjusting the pay-off tension to solve the problems raised in the above-mentioned background technology.
