[0002] A wire drawing die is a tool for stretching metal wire (rod) materials. In metal pressure processing, the metal is forced through the die under the action of external force, the metal cross-sectional area is compressed, and the tool that obtains the required cross-sectional shape and size is called a wire drawing die.

For example, unidirectional rotation can easily lead to uneven stress distribution on the copper wire in the die. Long-term unidirectional rotation may cause excessive wear or stress concentration on the copper wire in a specific area, thereby increasing the risk of copper wire breakage. Therefore, the present application provides a bidirectional alternating rotating wire drawing device to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1-3 A bidirectional alternating rotating wire drawing device is shown, comprising a first pulley 3 and a second pulley 4 connected by a belt, a bottom plate 1 with an L-shaped plate 2 and a support frame 10 installed thereon, and a driving motor 6 installed at the upper end of the L-shaped plate 2;

[0022] The first pulley 3 is fixedly sleeved on the outer wall of the hollow tube 8, the lower end of the hollow tube 8 passes through the support frame 10 and is rotatably connected to the support frame 10, and the inner wall of the hollow tube 8 is provided with a spiral groove 12 extending upward;

[0023] A reciprocating screw rod 7 is fixedly mounted on the output shaft of the driving motor 6, and the lower end of the reciprocating screw rod 7 passes through the axis of the hollow tube 8 and is rotatably connected to the bottom plate 1. An adapted moving nut 13 is threadedly sleeved on the reciprocating screw rod 7, and a sliding column 14 is mounted on the outer wall of the moving nut 13, and the end of the sliding column 14 is located in the inner cavity of the spiral groove 12. The moving nut 13 is slidably penetrated by a limiting rod 9, and the two ends of the limiting rod 9 are respectively fixedly connected to the L-shaped plate 2 and the support frame 10;

[0024] The second pulley 4 is fixedly sleeved on the rotating shaft 5. A wire drawing die 11 is detachably installed in the groove at the upper end of the rotating shaft 5. A through hole is provided at the axis of the rotating shaft 5, and the axis of the through hole is consistent with the axis of the drawing hole of the wire drawing die 11.

[0025] During operation, the metal wire passes through the wire drawing die 11 and the through hole in turn. The metal wire moves, and the driving motor 6 works, driving the moving nut 13 to make up and down linear motion on the reciprocating screw rod 7. When the moving nut 13 moves upward, the upper wall of the spiral groove 12 is squeezed by the sliding column 14 to drive the first pulley 3 to rotate counterclockwise, and the second pulley 4 is driven to rotate clockwise by the belt. When the moving nut 13 moves downward, the lower wall of the spiral groove 12 is squeezed by the sliding column 14 to drive the first pulley 3 to rotate clockwise, and the second pulley 4 is driven to rotate counterclockwise by the belt, and finally drives the wire drawing die 11 to do bidirectional alternating rotation. The bidirectional alternating rotation of the wire drawing die 11 can make the force on the metal wire in the die more uniform, avoid excessive concentration of stress in a specific area, which helps to reduce the possibility of metal wire breakage, improve production efficiency and product quality, and through bidirectional alternating rotation, the wear of the wire drawing die will be more uniform, avoiding excessive wear in a single direction, which helps to extend the service life of the die and reduce the frequency and cost of replacing the die.

[0026] As a preferred implementation in this embodiment, Figure 1 As shown, a magnetic block is provided in the groove at the upper end of the rotating shaft 5, and two bayonet holes are provided opposite to each other at the upper end of the rotating shaft 5;

[0027] Two clamping strips 111 are arranged opposite to each other on the outer wall of the wire drawing die 11 .

[0028] The two clamping strips 111 cooperate with the two bayonet holes to install the wire drawing die 11 in the groove of the rotating shaft 5, and limit the rotation of the wire drawing die 11. The magnetic force between the magnetic block and the wire drawing die can prevent the wire drawing die from moving in the vertical direction, which is conducive to the stable installation of the wire drawing die 11 in the groove. When the wire drawing die needs to be removed from the groove, the outer wall of the two clamping strips 111 can be pinched with two fingers to remove the wire drawing die 11 from the groove, which facilitates the disassembly and assembly of the wire drawing die 11.

[0029] As a preferred implementation in this embodiment, Figure 1 As shown, a push rod 112 is disposed on the outer wall of the two clamping strips 111 .

[0030] Two fingers of one hand can be placed under the corresponding push rod 112 respectively so that the fingers are in contact with the lower end of the push rod 112. The wire drawing die 11 can be moved out of the groove by moving the fingers upward, which is more conducive to the disassembly of the wire drawing die 11.

[0031] As a preferred implementation in this embodiment, Figure 2 As shown, a rotating ring 15 is rotatably provided on the outer side of the sliding column 14 , and the outer wall of the rotating ring 15 is in sliding contact with the inner wall of the spiral groove 12 .

[0032] The friction between the slide post 14 and the inner wall of the spiral groove 12 can be reduced, thereby extending the service life of the slide post 14 .

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
