The strander is generally used for splicing various wire and cable products. In the production process, what factors affect the quality of the strander's steel strand?
First, the selection of winch equipment and winch structure, the size of cross section and outside diameter, the number of single steel wire, the thickness of a single steel wire and the manufacturing length of the winch affect the quality of the stranding machine steel strand.
Second, if it is a concentric layer strand, first consider whether the number and size of the strander payoff disc are appropriate, and then consider the direction of the strand, pitch length, distortion, etc. If it is a stranded wire, it is also necessary to consider the deformation of the stock line, analyze the structure, specifications, and materials of the stranded wire, determine the technical data, and then choose the appropriate strander. When twisting products, in addition to the number and size of the pay-off reel, it is also important to determine the size of the take-up reel.
Third, the pitch length and twisted wire of various strands and bundles are specified. Pitch length can be calculated by the ratio of the outside diameter of the wire or bundle to the actual pitch. In actual production, a larger pitch ratio is generally used to improve productivity as much as possible. Strandings must be strictly enforced. Otherwise, the connection of the line will be affected.
So that's all for today's presentation. That's all for today. For the factors affecting the quality of the strander, I believe we all have a certain understanding.
