Description

Technical Field

[0001] This utility model relates to the field of metal product manufacturing, and in particular to a high-efficiency wire drawing and unwinding device for metal products. Background Technology

[0002] Metal wire is made from metal coils, bars, or rods as raw materials, processed through specialized equipment such as wire drawing and annealing machines. After multiple drawing-annealing-re-drawing-re-annealing processes, it is produced into various specifications and models of wire (or wire) products. The equipment used varies depending on the thickness of the metal wire. In metal processing, wire drawing machines are used to process wires or rods to achieve the required standards for diameter, roundness, internal metallographic structure, surface finish, and straightness. The unwinding device, as an important component of the wire drawing machine, functions to collect and store the pre-processed metal wire and move it to the next process.

[0003] While current wire drawing and unwinding devices can unload winding wheels full of metal wire, these disassembly and installation processes are all done manually. This method is relatively easy to load and unload winding wheels with lighter weight, but it is very laborious and time-consuming to load and unload winding wheels with heavier weight, which greatly reduces work efficiency and makes it impossible to effectively increase the production of metal wire.

[0057] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a high-efficiency wire drawing and unwinding device for metal products.

[0058] A high-efficiency wire drawing and unwinding device for metal products includes a base 1, and further includes:

[0059] A straightening component is disposed on the base 1, and the straightening component includes:

[0060] Mounting plate 2 is disposed on the base 1, and the mounting plate 2 is fixedly connected to the base 1;

[0061] A lead screw 3 is mounted on the mounting plate 2 and is threadedly connected to the mounting plate 2.

[0062] Mounting frame 4 is mounted on the lead screw 3. Mounting frame 4 is fixedly connected to lead screw 3 and slidably connected to mounting plate 2.

[0063] A first roller 5 is disposed on the mounting frame 4, and the first roller 5 is rotatably connected to the mounting frame 4;

[0064] The second roller 6 is disposed on the mounting plate 2, and the second roller 6 is rotatably connected to the mounting plate 2;

[0065] A support plate 7 is disposed on the base 1, and the support plate 7 is fixedly connected to the base 1;

[0066] The third roller 8 is disposed on the support plate 7, and the third roller 8 is rotatably connected to the support plate 7.

[0067] Rotating the lead screw 3 causes it to move downwards. The downward movement of the lead screw 3 drives the mounting frame 4, which is fixedly connected to the lead screw 3, to move downwards. This, in turn, drives the first roller 5, which is rolled and connected to the mounting frame 4, to move downwards. The first roller 5 moves downwards until the gap between it and the second roller 6 is just enough for the metal wire to pass through. The metal wire is straightened for the first time through the gap between the first roller 5 and the second roller 6. Then, the metal wire passes under the third roller 8, further enhancing the straightening effect of the metal wire.

[0068] Reference Figures 1 to 6 A fixing component is disposed on the base 1, the fixing component comprising:

[0069] A first drive motor 9 is mounted on the base 1 and is fixedly connected to the base 1.

[0070] A drive pulley 10 is disposed on the output shaft of the first drive motor 9, and the drive pulley 10 is fixedly connected to the output shaft of the first drive motor 9.

[0071] A conveyor belt 11 is placed on the drive pulley 10, and the conveyor belt 11 is tumblingly connected to the drive pulley 10;

[0072] A bidirectional threaded rod 12 is disposed on the base 1, and the bidirectional threaded rod 12 is tumbledly connected to the base 1;

[0073] Driven pulley 13 is disposed on the bidirectional threaded rod 12. Driven pulley 13 is fixedly connected to the bidirectional threaded rod 12 and is tactilely connected to the conveyor belt 11.

[0074] The slide plate 14 is disposed on the base 1 and is slidably connected to the base 1. The slide plate 14 is threadedly connected to the bidirectional threaded rod 12.

[0075] When the first drive motor 9 is started, the output shaft of the first drive motor 9 rotates, causing the drive pulley 10, which is fixedly connected to the output shaft of the first drive motor 9, to rotate. This, in turn, causes the conveyor belt 11, which is rolledly connected to the drive pulley 10, to rotate. The rotation of the conveyor belt 11 causes the driven pulley 13, which is rolledly connected to the conveyor belt 11, to rotate. This, in turn, causes the bidirectional threaded rod 12, which is fixedly connected to the driven pulley 13, to rotate. The rotation of the bidirectional threaded rod 12 causes the slide plate 14, which is threadedly connected to the bidirectional threaded rod 12, to rotate. Since the slide plate 14 is slidably connected to the base 1, the slide plate 14 can only perform outward translational movement, which facilitates subsequent operations.

[0076] Reference Figures 1 to 6 A winding assembly is disposed on the fixing assembly. The winding assembly cooperates with the fixing assembly, enabling the winding assembly to quickly and automatically detach from the constraint of the fixing assembly. The winding assembly includes:

[0077] The second drive motor 15 is disposed on the slide plate 14 and is fixedly connected to the slide plate 14.

[0078] The first rotating shaft 16 is disposed on the slide plate 14. The first rotating shaft 16 is rotatably connected to the slide plate 14. The first rotating shaft 16 is fixedly connected to the output shaft of the second drive motor 15. There are two sets of the first rotating shaft 16, which are symmetrically distributed on the winding assembly.

[0079] A fixing block 17 is disposed on the first rotating shaft 16. The fixing block 17 is fixedly connected to the first rotating shaft 16. There are two sets of fixing blocks 17, which are symmetrically distributed on the winding assembly.

[0080] The second rotating shaft 18 is disposed on the fixed block 17. The second rotating shaft 18 is slidably connected to the fixed block 17. There are two sets of the second rotating shaft 18, which are symmetrically distributed on the winding assembly.

[0081] A winding wheel 19 is disposed on the second rotating shaft 18, and the winding wheel 19 is fixedly connected to the second rotating shaft 18.

[0082] When the second drive motor 15 is started, the output shaft of the second drive motor 15 rotates, causing the first rotating shaft 16, which is fixedly connected to the output shaft of the second drive motor 15, to rotate. This causes the fixed block 17, which is fixedly connected to the first rotating shaft 16, to rotate. The rotation of the fixed block 17 causes the second rotating shaft 18, which is slidably connected to the fixed block 17, to rotate. This causes the winding wheel 19, which is fixedly connected to the second rotating shaft 18, to rotate. The rotation of the winding wheel 19 causes the metal wire to wind.

[0083] By cooperating with the fixing component, the winding wheel 19, which is full of metal wire, can quickly and automatically break free from the restriction of the first rotating shaft 16, and the empty winding wheel 19 can be quickly and automatically fixed.

[0084] Reference Figures 1 to 6 A winding assembly, mounted on the fixing assembly and cooperating with the winding assembly and the fixing assembly, enables the wound metal wire to be automatically and quickly unloaded and replaced, thereby improving work efficiency. The winding assembly includes:

[0085] A support column 20 is disposed on the base 1, and the support column 20 is fixedly connected to the base 1;

[0086] A servo motor 21 is mounted on the support column 20, and the servo motor 21 is fixedly connected to the support column 20;

[0087] A drive shaft 22 is mounted on the support column 20 and is rotatably connected to the support column 20. The drive shaft 22 is also fixedly connected to the output shaft of the servo motor 21.

[0088] Mounting post 23 is disposed on the drive shaft 22, and the mounting post 23 is fixedly connected to the drive shaft 22;

[0089] An electric telescopic rod 24 is mounted on the mounting column 23 and is fixedly connected to the mounting column 23. There are several sets of electric telescopic rods 24, which are evenly and symmetrically distributed on the mounting column 23.

[0090] A connecting plate 25 is disposed on the mounting column 23. The connecting plate 25 is slidably connected to the mounting column 23 and fixedly connected to the electric telescopic rod 24. There are several sets of connecting plates 25, which are evenly and symmetrically distributed on the mounting column 23.

[0091] Clamping blocks 26 are disposed on the connecting plate 25. The clamping blocks 26 are fixedly connected to the connecting plate 25 and are rotatably connected to the second rotating shaft 18. There are several sets of clamping blocks 26, which are evenly and symmetrically distributed on the mounting column 23.

[0092] Start the servo motor 21. The output shaft of the servo motor 21 rotates, causing the transmission shaft 22, which is fixedly connected to the output shaft of the servo motor 21, to rotate. This, in turn, causes the mounting post 23, which is fixedly connected to the transmission shaft 22, to rotate. The rotation of the mounting post 23 causes the connecting plate 25, which is slidably connected to the mounting post 23, to rotate. This, in turn, causes the clamping block 26, which is fixedly connected to the connecting plate 25, to rotate. The rotation of the clamping block 26 causes the second rotating shaft 18, which is slidably connected to the clamping block 26, to rotate. This continues until the winding wheel 19, which is fixedly connected to the second rotating shaft 18, rotates to the appropriate position. Then, turn off the servo motor 21 and start the electric telescopic rod 24. The electric telescopic rod 24 extends, causing the connecting plate 25, which is fixedly connected to the electric telescopic rod 24, to move outward. This, in turn, causes the clamping block 26, which is fixedly connected to the connecting plate 25, to move outward until the winding wheel 19 disengages from the clamping block 26.

[0093] By cooperating with the winding assembly and the fixing assembly, the metal wire wound by the winding assembly can be automatically and quickly unloaded by the fixing assembly and the winding assembly. Furthermore, the empty winding wheel 19 can be automatically and quickly installed on the winding assembly by the winding assembly and the fixing assembly, thereby greatly improving the automation level of the device, increasing work efficiency and the output of metal wire.

[0094] Working principle: Refer to Figures 1 to 6Rotating the lead screw 3 causes it to move downwards. This downward movement of the lead screw 3 drives the mounting frame 4, which is fixedly connected to the lead screw 3, to move downwards. This, in turn, drives the first roller 5, which is rolled and connected to the mounting frame 4, to move downwards. The first roller 5 moves downwards until the gap between it and the second roller 6 is just wide enough for the metal wire to pass through. The metal wire is straightened for the first time through the gap between the first roller 5 and the second roller 6. Then, the metal wire passes under the third roller 8, further enhancing the straightening effect. The second drive motor 15 is then activated. The output shaft of the second drive motor 15 rotates, causing the first rotating shaft 16, which is fixedly connected to the output shaft of the second drive motor 15, to rotate. This, in turn, causes the fixing block 17, which is fixedly connected to the first rotating shaft 16, to rotate. The rotation of the fixed block 17 drives the second rotating shaft 18, which is slidably connected to the fixed block 17, to rotate. This, in turn, drives the winding wheel 19, which is fixedly connected to the second rotating shaft 18, to rotate. The rotation of the winding wheel 19 drives the metal wire to wind. When the winding wheel 19 is fully wound with metal wire, the first drive motor 9 is started. The output shaft of the first drive motor 9 rotates, driving the drive pulley 10, which is fixedly connected to the output shaft of the first drive motor 9, to rotate. This drives the conveyor belt 11, which is rollably connected to the drive pulley 10, to rotate. The rotation of the conveyor belt 11 drives the driven pulley 13, which is rollably connected to the conveyor belt 11, to rotate. This drives the bidirectional threaded rod 12, which is fixedly connected to the driven pulley 13, to rotate. The rotation of the bidirectional threaded rod 12 drives the... The threaded sliding plate 14 rotates. Since the sliding plate 14 is slidably connected to the base 1, the sliding plate 14 can only move outwards. The outward movement of the sliding plate 14 drives the first rotating shaft 16, which is slidably connected to the sliding plate 14, to move outwards, thereby driving the fixed block 17, which is fixedly connected to the first rotating shaft 16, to move outwards until the fixed block 17 disengages from the second rotating shaft 18. This causes the winding wheel 19, which is full of metal wire, to disengage from its restraints, activating the servo motor 21. The output shaft of the servo motor 21 rotates, driving the transmission shaft 22, which is fixedly connected to the output shaft of the servo motor 21, to rotate. This drives the mounting post 23, which is fixedly connected to the transmission shaft 22, to rotate. The rotation of the mounting post 23 drives the connecting rod slidably connected to the mounting post 23 to rotate. The connecting plate 25 rotates, thereby causing the clamping block 26, which is fixedly connected to the connecting plate 25, to rotate. The rotation of the clamping block 26 causes the second rotating shaft 18, which is rolledly connected to the clamping block 26, to rotate, thereby causing the winding wheel 19, which is fixedly connected to the second rotating shaft 18, to rotate. When the winding wheel 19 rotates to the appropriate position, the servo motor 21 is turned off, and the electric telescopic rod 24 is started. The electric telescopic rod 24 extends, causing the connecting plate 25, which is fixedly connected to the electric telescopic rod 24, to move outward. This causes the clamping block 26, which is fixedly connected to the connecting plate 25, to move outward, until the winding wheel 19 disengages from the clamping block 26 and falls onto the base 1. This allows for quick replacement of the winding wheel 19, which is full of metal wire, with the empty winding wheel 19, thereby improving work efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
