Concentric high-speed stranding machine

Abstract

The invention discloses a concentric high-speed stranding machine, which comprises a rack and a stranding system arranged on the rack. The concentric high-speed stranding machine also comprises a traction machine and a take-up machine, which are used for carrying out traction and take-up and rolling on the stranded cables in sequence. The concentric high-speed stranding machine is characterized in that the stranding system comprises a bracket rotatably connected with the rack through bearing pedestals at the two ends; the bracket is uniformly equipped with a plurality of paying-off wheels in the same line direction; the paying-off wheels can rotate automatically and can also rotate synchronously with the bracket; and one side surface, opposite to an end frame, at the tail end of the bracket is uniformly provided with cable outlets. The provided concentric high-speed stranding machine is unique in structure; in the stranding machine, the bracket drives the paying-off wheels to rotate together, and the paying-off wheels are arranged uniformly in the same line direction, so that the bracket is smaller in overall structure; and therefore, the stranding machine is small in space occupation, fast in stranding speed and low in energy consumption.

Description

technical field [0001] The patent of the invention relates to a stranding machine used in the wire and cable industry, in particular to a concentric high-speed stranding machine. Background technique [0002] In the wire and cable industry, stranding is the basic process for the production of overhead wires and conductive cores of power cables, and stranding machines have emerged as the times require and are becoming more and more diverse. Stranding machine is a kind of wire that can be widely used in various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) Wire, telephone wire, PVC wire, network wire, etc.) twisting mechanical equipment, so that multiple single conductors are twisted into one strand to meet the technical requirements of the wire. [0003] According to the twisting method, the stranding machine can generally be divided into single stranding machine, pair stranding machine, high-speed strandin...

Problems solved by technology

[0003] According to the twisting method, the stranding machine can generally be divided into single stranding machine, pair stranding machine, high-speed stranding machine, untwisting machine, cage stranding machine, frame stranding machine, tubular stranding machine and disc stranding machine Machines, etc., the realization structure of each method is also diversified, and in most cases, the pay-off wheel is self-propagating but does not rotate with the frame, or it is self-propagating and rotates with the frame at the same time, and its work efficiency is not high. , the energy consumption is relatively large, the arrangement of the pay-off wheels is not in a straight line, the relative distance is relatively long, the energy consumption is high, the overall machine submission is relatively large, and the structure is complex, and the procurement cost is high

The stranding machine's stranding material is generally copper, aluminum, and steel. Common stranding machines are tubular stranding machines and fork-type stranding machines. The advantages of tubular stranding machines are fast stranding speed and stable stranding quality. The disadvantage is that the structure is complex, the volume is large, the cost is high, the floor area is large, and the power consumption is large. The advantage of the fork-type stranding machine is that the stranding and quality are stable, the footprint is small, and the cost is low. The disadvantage is that the twisting speed is slow. , low production efficiency, 4-5 times slower than tubular stranding machine under the same storage capacity

Both of the above two stranding machines need to straighten the subsequent twisted cables and then be pulled into the take-up machine by the tractor, which is troublesome and requires many procedures.
