Technical Field

[0001] This utility model relates to the field of wire drawing technology, and in particular to a novel wire drawing device for a wire bending machine. Background Technology

[0002] A wire bending machine is a specialized piece of equipment for processing metal wires. It is primarily used to shape metal wires into specific forms to meet the needs of various applications. Widely used in industries such as electronics, automotive, and home appliances, the wire bending machine efficiently completes the wire bending, folding, and shaping operations, improving production efficiency and finished product quality. The wire drawing device is a crucial component of the wire bending machine; its main function is to accurately extract the metal wire from the raw material roll, ensuring smooth flow and stable supply of the wire during processing.

[0003] Existing wire drawing devices for wire bending machines typically employ simple mechanical structures, relying on friction or spring mechanisms to extract the metal wire. While these traditional devices can achieve basic wire drawing functions, their lack of design flexibility often requires users to use tools to disassemble and replace the wire drawing plate. This not only increases the difficulty of replacement but also affects work efficiency. Therefore, a novel wire drawing device for wire bending machines is proposed to solve these problems.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-5This utility model provides an embodiment of a novel wire drawing device for a wire bending machine, comprising a mold base 1 for supporting the entire device, providing a stable foundation, and ensuring the accuracy and reliability of the wire drawing process. A lower wire drawing plate 2 is provided on the top of the mold base 1, and the lower wire drawing plate 2 is connected to an upper wire drawing plate 3 via a hinge, thus forming a flexible and adjustable wire drawing structure. This facilitates opening the wire drawing plates for cleaning the wire path. A fixing mechanism is provided on the side wall of the mold base 1 for fixing the wire drawing plates. Closing mechanisms are provided on the side walls of the lower wire drawing plate 2 and the upper wire drawing plate 3 for controlling the closing of the wire drawing plates. The fixing mechanism includes a pin 6 and a recess 17 formed inside the lower wire drawing plate 2. The mold base 1 has a rotating plate 5 rotatably connected to its side wall, and a pin 6 is slidably connected to the inside of the rotating plate 5. The pin 6 is used to lock the position of the wire drawing plate to ensure that the plate does not easily move during the wire drawing process, thereby enhancing the accuracy of the operation. The pin 6 is slidably connected to the inside of the recess 17 to ensure the stability of the lower wire drawing plate 2. A fixing plate 7 is fixedly connected to the side wall of the pin 6, and a first spring 8 is sleeved on the side wall of the pin 6. One end of the first spring 8 is fixedly connected to the side wall of the rotating plate 5, and the other end of the first spring 8 is fixedly connected to the side wall of the fixing plate 7, which provides the pin 6 with the ability to automatically reset when the pressure is lost. A pull ring 9 is fixedly connected to the side wall of the fixing plate 7 to facilitate the operator to pull the pin 6.

[0033] Reference Figures 3-6 The closing mechanism includes a locking plate 11 and a slot plate 14. A fixing block 10 is fixedly connected to the side wall of the lower wire-drawing plate 2. The locking plate 11 is fixedly connected to the side wall of the fixing block 10, ensuring the stability of the entire mechanism and preventing accidental displacement during operation. A fixing block 2 12 is fixedly connected to the side wall of the upper wire-drawing plate 3. A connecting frame 13 is rotatably connected inside the fixing block 2 12. The side wall of the slot plate 14 is fixedly connected to the side wall of the connecting frame 13, providing additional flexibility to the slot plate 14. A connecting plate 16 is fixedly connected between the slot plates 14, allowing the slot plates 14 on the same side to deflect synchronously. The interior has a groove, and the protrusion at the end of the card plate 11 matches the groove, achieving precise docking and further ensuring the stability of the wire drawing plate closure. A second spring 15 is provided between the fixing block 2 12 and the card slot plate 14. One end of the second spring 15 is fixedly connected to the side wall of the fixing block 2 12, and the other end of the second spring 15 is fixedly connected to the side wall of the card slot plate 14, providing the card slot plate 14 with the ability to reset, so that it can quickly reset when it loses force. A card block 4 is fixedly connected to the bottom of the lower wire drawing plate 2, and the side wall of the card block 4 is slidably connected to the inside of the mold base 1, ensuring the initial positioning of the lower wire drawing plate 2.

[0034] Working principle: When it is necessary to clean the wire drawing channel in the wire drawing plate, the connecting plate 16 can be flipped to drive the slot plate 14 to move, thereby stretching the spring 15 and separating it from the slot plate 11, thus releasing the lock of the lower wire drawing plate 2 and the upper wire drawing plate 3. With the cooperation of the hinge, the lower wire drawing plate 2 and the upper wire drawing plate 3 can be opened to clean the wire drawing channel. After cleaning, the mold base 1 and the lower wire drawing plate 2 are closed. During the closing process, the slot plate 14 will slide along the surface of the slot plate 11 and gradually deflect the slot plate 14, stretching the spring 15. When the groove inside the slot plate 14 is aligned with the protrusion at the end of the slot plate 11, the spring 15 will lose the pressure it receives, thereby pulling the slot plate 14 to move and engage with the slot plate 11, thus completing the closing of the lower wire drawing plate 2 and the upper wire drawing plate 3.

[0035] When the wire drawing plate needs to be replaced, the pull ring 9 can be pulled to move the pin 6 and pull it out from the inside of the lower wire drawing plate 2. Then, the rotating plate 5 is deflected so that the pin 6 is misaligned with the concave hole 17. After all the pins 6 have been removed, the mold base 1 and the lower wire drawing plate 2 can be lifted upwards to complete the disassembly. When installing, insert the locking block 4 at the bottom of the lower wire drawing plate 2 into the inside of the mold base 1. After it is inserted into place, while pulling the pull ring 9, the rotating plate 5 is deflected to move the pin 6. When the pin 6 moves to be aligned with the concave hole 17, the pull ring 9 is released. At this time, the 8 loses the force it receives and pulls the fixing plate 7 to reset, thereby inserting the pin 6 into the inside of the concave hole 17 and completing the fixing of the lower wire drawing plate 2.

[0036] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
