Tube-type line strander

Abstract

A rube-type line strander comprises a frame, a rotary stranded body, a gear transmission case, a drive motor, a core wire drawing tray and a contour drawing tray; the rotary stranded body is supported on the frame by supporting seats at head and tail ends and carries out rotation motion driven by the motor and transmitted by the gear transmission case; the frame is provided with a plurality of riding wheel assemblies which are arranged in a disperse way along the longitudinal direction of the frame and are supported at the waist of the rotary stranded body; the contour drawing tray is arranged in the abdominal cavity of the rotary stranded body which is composed of a cylinder body and a double-bow type tray bearing body assembly, the cylinder body is located at the head end and the double-bow type tray bearing body assembly is located at the tail end, and the two parts are rigidly connected into a whole; the double-bow type tray bearing body comprises a tray bracket and a double-bow type guide plate, the double-bow type guide plate is provided with two bow plates which are arranged symmetrically in opposite direction at the periphery of the tray bracket in an enclosure structure and are connected with the double-bow type guide plate in a detachable way; the tray bracket is used for installing the core wire drawing tray, the bow plates are used for distributing and guiding contours drawn by the contour drawing tray. The invention can carry out twice stranding to manufacture cables with two layers of contours, and the maximum diameter of section can reach above 25 mm.

Description

technical field [0001] The invention relates to wire and cable processing equipment, in particular to a tubular stranding machine, which belongs to the field of electrical machinery. Background technique [0002] Multi-strand wires and cables and steel wire ropes are manufactured by stranding machines. For small-section stranded cables with only core wires and one layer of circumference, they are usually processed by tubular stranding machines; for large-section strands with multiple layers of circumference If the cable is combined, it is processed by a frame-type stranding machine. The working process of the frame-type stranding machine is carried out step by step. Combine the second layer of circumference, and so on, twist the outer circumference layer by layer until the outermost circumference is twisted. [0003] At present, the tubular stranding machine has two specifications for twisting 7 single wires or 13 single wires, which can meet the requirements of twisting co...

Problems solved by technology

[0008]2. During secondary stranding, the diameter of the core wire is relatively large. The mold (stranding point) is too far away, cannot be pressed tightly, and cannot meet the stranding requirements
