A wire twisting machine and its pre-twisting and pressing device

Abstract

The invention discloses a stranding machine and a pre-twisting compaction apparatus. The pre-twisting compaction apparatus comprises a frame which is provided with two shaft support assemblies, two rotating shafts whose axial leads are superposed and a driving assembly driving the rotating shaft to rotate, wherein the two rotating shafts are supported by the two shaft support assemblies in a one-to-one corresponding manner; and a pre-twisting compaction assembly which is arranged between the two rotating shaft and comprises a first module and a second module, wherein the first module and the second module each comprise a die holder and a pre-twisting compaction mold core mold core detachably arranged in the die holder, one side of the die holder of the first module is connected with one rotating shaft, one side of the die holder of the second module is connected with the other rotating shaft, and the die holders of the first module and the second module are relatively fixedly connected. Through such arrangement, the pre-twisting compaction apparatus provided by the invention can prevent the problems of quite low efficiency, high cost and too much consumed time and labor due to arrangement of a conventional pre-twisting compaction apparatus in the prior art.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a stranding machine and a pre-twisting and pressing device thereof. Background technique [0002] In the cable production process, after multiple single wires are twisted together by the stranding mold, according to the type of cable and the processing technology requirements of the cable, some cables need to be pre-twisted and compacted after forming, that is, Compress the cable from the radial direction of the cable. [0003] If the cable needs to be pre-twisted and compressed, a pre-twisted and compressed device is usually installed between the twisted wire mold and the rewinding reel. The pre-twisted and compressed device includes a machine base and a mold base, and a pair of pressure wheels are arranged on the mold base. , the cable passes between the two pressure rollers, and the cable can be squeezed tightly under the pressure of the two pressure rollers.

Problems solved by technology

[0005] However, in the prior art, if the cable needs to be pre-twisted and compressed, it is necessary to reset the pre-twisted and compressed device on the basis of the existing stranded wire production line. If it is necessary to perform multi-directional or multiple pre-twisted For compaction, it is necessary to contact the equipment manufacturer again to add a pre-twist compaction device, which is inefficient and expensive, and adding a separate pre-twist compaction device is also time-consuming and labor-intensive when arranging the production line

Each work form is an independent structure, and it is difficult to switch between work forms

[0006] In addition, in the prior art, the pre-twist compression device and the parallel mold base cannot coexist, and the two need to be set separately, which also causes waste of equipment and a reduction in work efficiency

[0007] Therefore, how to solve the problems of low efficiency, high cost, and time-consuming and labor-consuming problems of setting the pre-twist compression device in the prior art has become an important technical problem to be solved by those skilled in the art.
