General purpose type wire stranding machine

Abstract

This invention discloses an all-purpose strander, which comprises a setting-out part, a branching matched part and a main frame strander contractor part, wherein the setting-out part comprises the setting-out frame (1) and setting-out seat, and the setting-out frame (1) is installed erectly with several setting-out seats in it; the main shafts of each setting-out seat are arranged horizontal in parallel, and around each setting-out seat it sets guide wheel (15) and guide pipe (2); the tension automatic adjust device are set on each setting-out seat. The strander is modularized and is fit for stranding steel cord of several formats.

Description

technical field [0001] The invention relates to a general-purpose stranding machine used in the steel cord twisting process. Background technique [0002] Steel cord is the material required in the manufacture of rubber tires. It is made of multiple steel wires twisted on a stranding machine. The stranding machine is generally divided into a wire-releasing part, a split-line mold closing part, and a main strand twisting and receiving part. The thread forms a specific arrangement structure through the thread distribution plate, and then reaches the main machine through the closed mold, and twists and takes up the strands through the rotation of the cradle of the main machine. [0003] At present, each monofilament in the pay-off part needs a separate rotating pay-off space. It is equipped with a cradle frame and a flywheel between the left and right spindles. For the I-shaped wheel, when the number of monofilaments is large, multiple cradles are required, which has a complex...

Problems solved by technology

When the cord structure needs to be replaced when the wire distribution disc needs to be replaced, the two ends of the guide rail must be disassembled from the bracket, and then the screws on the base of the wire distribution disc must be loosened to replace it. The workload is large (see Figure 7 )

In addition, after the steel wire on the pay-off I-shaped wheel passes through the sub-disc to the closed die, it is directly over-twisted or enters the main machine, which will easily cause uneven twisting of the steel cord, and unevenness between monofilaments and strands. Properly overlapping together, that is, the phenomenon of back wire, affects the quality of the steel cord

[0005] In addition to the above, due to the structure of the pay-off part and the split-line mold closing part, the existing stranding machine can only adapt to the twisting of steel cords with a specific structure. When the structure of the steel cord changes, the components of the stranding machine Unable to flexibly change accordingly, only to re-customize the new stranding machine, resulting in huge investment costs
