[0025] Such as Figures 1 to 4As shown in the figure, in an embodiment of the present utility model, a wire stranding die is involved, which includes a die body 10. The die body 10 is provided with a stranding forming cavity 20. The stranding forming cavity 20 includes an inlet wire area 1, a lubricating area 2, a compression area 3, a shaping area 4, and an outlet wire area 5 arranged in sequence. The inlet wire area 1, the lubricating area 2, and the compression area 3 are all arranged in a trumpet shape and gradually shrink in sequence. The shaping area 4 is arranged in a straight cylinder shape. The outlet wire area 5 is used to export the wire after being shaped in the shaping area 4. This embodiment is used for stranding of ultra-thin metal wires. The stranding forming cavity 20 includes an inlet wire area 1, a lubricating area 2, a compression area 3, a shaping area 4, and an outlet wire area 5, which are arranged in sequence and gradually shrink in a trumpet shape. Such a design is conducive to effectively forming the wire, ensuring the quality and efficiency of wire forming. The design of the lubricating area 2 is conducive to sufficient lubrication when the wire passes through, reducing the friction of the wire during the forming process, protecting the surface of the wire, and avoiding wire damage and quality problems caused by friction. The trumpet shape of the compression area 3 can compactly compress the wires together, ensuring the firm connection and stability of the wires. The straight cylinder shape design of the shaping area 4 can accurately shape the stranded wire, making the shape and size of the stranded wire meet the requirements, and improving the quality and stability of the finished product. The outlet wire area 5 is used to export the shaped wire, ensuring that the formed wire can be smoothly led out and continue subsequent processing or use. The present utility model has many advantages such as high forming efficiency, good product quality, and strong versatility, and can meet the stranding requirements of different types of metal wires in different industries, such as stainless steel wires, copper wires, aluminum alloy wires, etc., especially for wire forming, and has a wide application prospect.
[0026] The die body 10 is arranged in a cylindrical shape, and the stranding forming cavity 20 is arranged at the axis center of the die body 10. Specifically, a right-angle edge is provided on the outer edge of the die body 10. In this embodiment, the die body 10 is arranged in a cylindrical shape, and the stranding forming cavity 20 is arranged at the axis center. Such a design ensures the stability and symmetry of the die, which is conducive to the stable operation during the forming process and the consistency of the finished product quality. The right-angle edge provided on the outer edge of the die body 10 facilitates the positioning and installation of the structure and ensures stability. The cylindrical die body 10 and the stranding forming cavity 20 arranged at the axis center are conducive to ensuring that the wire receives uniform force during the forming process, making the forming more uniform and stable. The cylindrical die body 10 has a simple structure, is easy to process and manufacture, and reduces the production cost. Due to the simple cylindrical design, this die is applicable to different types and diameters of wires and has strong versatility.
[0027] At both ends of the mold body 10, a first surface 101 and a second surface 102 are respectively provided. An arc edge 11 is provided between the first surface 101 and the wire inlet area 1. In this embodiment, the provision of the arc edge 11 facilitates the smooth entry of the wire from the first surface 101 into the wire inlet area 1, reducing the loss or distortion of the wire caused by the resistance at the transition, and ensuring the smooth entry of the wire into the stranding and forming cavity 20. The design of the arc edge 11 can reduce the friction and loss of the wire when entering the stranding and forming cavity 20, and extend the service life of the wire. The design of the arc edge 11 enables the wire to enter the stranding and forming cavity 20 in a more stable and uniform manner, which is beneficial to ensuring the consistency and stability of the forming quality.
[0028] An angle a is formed between the wire inlet area 1 and the axis of the mold body 10, and the angle of the angle a is 35° to 50°. An angle b is formed between the lubrication area 2 and the axis of the mold body 10, and the angle of the angle b is 30° to 45°. An angle c is formed between the compression area 3 and the axis of the mold body 10, and the angle of the angle c is 10° to 25°. Specifically, transition arc surfaces are provided between the wire inlet area 1 and the lubrication area 2, the compression area 3, the shaping area 4, and the wire outlet area 5. In this embodiment, by reasonably setting the angles and the transition arc surfaces between the wire inlet area 1 and the lubrication area 2, the compression area 3, the shaping area 4, and the wire outlet area 5, the wire can be guided through the entire forming cavity more smoothly, reducing the loss or distortion of the wire caused by the resistance at the transition, and ensuring the smooth entry of the wire into the stranding and forming cavity 20. By reasonably setting the angles and the transition arc surfaces, the friction during the forming process of the wire can be reduced, the wear and loss on the surface of the wire are decreased, and the service life of the wire is extended. Reasonably setting the angles and the transition arc surfaces is beneficial to ensuring that the wire is subjected to a uniform force during the entire forming process, making the forming more uniform and stable, and improving the quality and stability of the finished product. By setting different ranges of angles, it can be flexibly adjusted according to wires of different diameters and materials, ensuring the wide range of applicability and versatility.
[0029] The axial length dimension of the compression area 3 is larger than the axial length dimensions of the wire inlet area 1 and the lubrication area 2. In this embodiment, since the axial length dimension of the compression area 3 is larger, it means that the wire will be compressed for a longer time and to a greater extent when passing through the compression area 3, which is beneficial to the forming and connection effect of the wire. Ensure that the wire can be fully compacted and connected during this process, improving the forming quality and stability.
[0030] The wire outlet area 5 includes an inner wire outlet area 51 and an outer wire outlet area 52. One end of the inner wire outlet area 51 is connected to the shaping area 4, and the other end is connected to the outer wire outlet area 52. In this embodiment, the inner wire outlet area 51 connects the shaping area 4 and the outer wire outlet area 52. In the design of the inner wire outlet area 51, it is necessary to ensure that the wire can be smoothly led out from the shaping area 4 and stably connected to the outer wire outlet area 52, avoiding resistance or loss due to the transition, and ensuring the smooth wire outlet. The reasonably designed inner wire outlet area 51 can ensure that the wire will not be subjected to additional twisting or damage during the leading-out process, which is beneficial to ensuring the stability and consistency of the forming quality.
[0031] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model.
