Abstract
Description
Technical Field
[0001] The utility model relates to a tangent device, in particular to a tangent device used for processing prestressed steel strands, and belongs to the technical field of prestressed steel strands. Background Art
[0002] Prestressed steel strand is a material made of high-strength, multi-strand steel wires twisted together. It is usually used in prestressed concrete structures. In prestressing technology, the steel strand is put under stress by pre-applied tension, so as to resist the tension and bending moment that the structure may be subjected to during use in advance. This prestressing effect can significantly improve the bearing capacity and durability of concrete components. The unique high tensile strength and good ductility of prestressed steel strand enable it to be widely used in bridges, elevated roads, buildings and other types of prestressed concrete components, and can effectively reduce the weight of the structure, extend its service life, and reduce the occurrence of cracks.
[0003] During the processing of steel strands, in order to make the steel strands to a specific length to meet engineering requirements, a wire cutting device is used to cut the steel strands. However, the existing wire cutting equipment may not be convenient for fixing the incision during the steel strand cutting process. Since the steel strands are twisted together by multiple wire bundles, the steel strands may fall apart during cutting, thereby affecting the cutting accuracy, resulting in an uneven cut end face or burrs, which in turn affects the subsequent connection or construction quality. Secondly, the fall of the steel strands may also lead to uneven cutting and increase material waste. At the same time, the fall of the wire bundle may cause the steel strand to pop out suddenly, increasing the safety risk at the work site and endangering the safety of the operator. In addition, debris may be generated while the steel strand is being cut. However, the existing wire cutting equipment may not be convenient for collecting and processing the debris generated during the wire cutting process. The operator may inhale the debris during the processing process, thereby affecting his health.
[0004] Therefore, a wire cutting device for processing prestressed steel strands is proposed. Utility Model Content

[0028] By setting up the fixing mechanism 8, the accuracy and repeatability of the cutting process can be ensured, thereby improving the cutting quality. Secondly, it can avoid the scattering of the ends of the steel strands after cutting, reduce safety risks, and facilitate subsequent processing and use, such as connection or welding. In addition, reducing the scattering of the wire harness can also help reduce material loss and improve material utilization.
[0029] Example 2
