Description

Technical Field

[0001] The utility model relates to the technical field of wire rope production equipment, in particular to a constant-tension forming device for a rope making machine. Background Art

[0002] With the development of the times, wire ropes are used more and more widely. They are widely used in many fields such as elevators, automobiles, medical treatment, fishing, tower cranes, and drilling. The twisting and forming production of wire ropes goes through multiple steps, including pre-forming, closing and compressing, and straightening.

[0003] During the wire rope twisting process, due to uneven control of the pay-off tension, single-wire or multi-wire protrusion phenomena are likely to occur when the steel wires are closed, resulting in uneven loosening of the rope or strand, which affects the product quality. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a constant-tension forming device for a rope making machine, which has the advantages of simple structure, convenient operation, and easy maintenance.

[0005] To achieve the above purpose, the utility model is realized by adopting the following technical solutions:

[0006] A constant-tension forming device for a rope making machine includes a forming damping disc and a support. The forming damping disc is a trumpet-shaped curved body, and the support is a columnar body. A circular wire passing hole is provided at the center of the forming damping disc. Guide wheel assemblies are evenly distributed in the circumferential direction at the edge of the forming damping disc. The guide wheel assemblies are arranged in an opening groove, and an installation plane is provided outside the opening groove.

[0007] The guide wheel assembly includes a guide wheel and a guide wheel shaft. The guide wheel is installed on the guide wheel shaft through a first bearing and a second bearing. A first spacer and a second spacer are respectively provided on both sides of the first bearing and the second bearing. A wire passing groove is provided on the circumference of the guide wheel.

[0008] The cross-section of the wire passing groove is V-shaped.

[0009] The guide wheel shaft is fastened to the installation plane with fixing screws.

[0010] A square wire passing hole with a diameter larger than the circular wire passing hole is provided at the center of the support.

[0011] The opening groove is arranged radially along the forming damping disc.

[0012] The installation plane is perpendicular to the opening groove.

[0013] Bolt holes for installing the forming device are further provided in the middle of the forming damping disc.

[0014] Compared with the existing technology, the beneficial effects of the utility model are:

[0015] The utility model has a simple structure, is simple and convenient to operate, and saves working time. Before closing, the steel wire bypasses the guide wheel, slides along the curved surface of the formed damping disc and then closes. The friction between the steel wire and the curved surface controls the tension, provides constant tension, and thus improves the quality of the steel rope product. BRIEF DESCRIPTION OF THE DRAWINGS
