Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of small drawing machines, in particular to a wire clamping structure for reserving wire heads during the coil changing of an automatic coil-changing small drawing machine. Background Technique
[0002] Coil changing of a small drawing machine means replacing the coil for drawing wire during the operation of the small drawing machine. A small drawing machine is a mechanical device for wire drawing and is widely used in the drawing process of various metal wire rods. During the drawing process, due to the continuous consumption of the wire rod, the coil needs to be replaced regularly to maintain the continuity of production.
[0003] In the prior art, during the coil changing process of a small drawing machine, after the wire is wound around one take-up coil, it is then wound around another coil. Before winding around the other coil, the machine is first stopped, the first take-up coil is removed, and then the wire is cut by a cutting mechanism. However, the end of the cut wire will rotate inertia with the previous take-up coil, making it difficult to easily find the wire end and fix it, thus affecting the winding of the subsequent coil and making it inconvenient for subsequent processing. Content of the Utility Model
[0004] The purpose of the utility model is to provide a wire clamping structure for reserving wire heads during the coil changing of an automatic coil-changing small drawing machine, so as to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A wire clamping structure for reserving wire heads during the coil changing of an automatic coil-changing small drawing machine, including: the body of the automatic coil-changing small drawing machine, a support plate is fixedly installed on one side of the body of the automatic coil-changing small drawing machine, an electric cylinder is arranged on one side of the support plate, and a wire blocking plate is arranged on the other side of the support plate.
[0006] A push plate is arranged on one side of the wire blocking plate, a sliding rod is fixedly sleeved inside the push plate, one end of the sliding rod is fixedly connected with a buffer, and one end of the buffer is fixedly connected with a wire clamping plate.
[0007] Preferably, the electric cylinder is fixedly installed on the support plate, and the output end of the electric cylinder penetrates through the support plate and is fixedly connected with one side of the wire blocking plate.
[0008] Preferably, a limiting hole is opened on the upper surface of the wire blocking plate, and the limiting hole is slidably connected with the sliding rod. A groove is opened on the lower surface of the wire blocking plate, and the groove is slidably connected with the side wall of the wire clamping plate.
[0009] Preferably, fixing frames are fixedly connected to both sides of the wire blocking plate, and both sides of the push plate are slidably connected with the fixing frames.
[0010] Preferably, a connecting seat is fixedly connected to the upper surface of the push plate, a threaded rod is arranged above the connecting seat, both ends of the threaded rod are rotatably sleeved on the top of the fixing frame, and a threaded sleeve is sleeved on the threaded rod.
[0011] Preferably, the threaded sleeve is rotatably connected to one end of the connecting rod through a pin shaft, and the other end of the connecting rod is rotatably connected to the connecting seat through a pin shaft. One side of one of the fixing frames is fixedly installed with a motor, and the output end of the motor is fixedly connected to one end of the threaded rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The electric cylinder fixedly installed on one side of the support plate drives the wire blocking plate to move. When the wire cutting mechanism needs to cut the wire, when the electric cylinder drives the wire blocking plate to move to the edge position of the wire collecting disc, when the wire is cut, the previous wire collecting disc stops running, and the wire blocking plate blocks the cut wire to prevent it from being carried away by the inertia during the rotation of the wire collecting disc. The push plate drives the sliding rod to move, and the sliding rod drives the buffer to move, so that the buffer drives the wire clamping plate to move towards the direction close to the wire collecting disc. Furthermore, under the extrusion of the wire clamping plate, the wire head is pressed down. The wire head is located outside the disc, leaving the wire head for the next process to use.

[0019] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clear and understandable, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0020] Embodiment 1: Please refer to Figures 1 - 4, the present utility model provides a technical solution: a wire clamping structure for the reserved wire head during the coil changing of an automatic coil-changing small drawing machine, including: the body 1 of the automatic coil-changing small drawing machine, a support plate 2 is fixedly installed on one side of the body 1 of the automatic coil-changing small drawing machine, an electric cylinder 3 is arranged on one side of the support plate 2, a wire blocking plate 4 is arranged on the other side of the support plate 2, a push plate 5 is arranged on one side of the wire blocking plate 4, a sliding rod 6 is fixedly sleeved inside the push plate 5, one end of the sliding rod 6 is fixedly connected with a buffer 7, and one end of the buffer 7 is fixedly connected with a wire clamping plate 8.
[0021] A support plate 2 is fixedly installed on one side of the body 1 of the automatic coil-changing small drawing machine. The wire blocking plate 4 is driven to move by the electric cylinder 3 fixedly installed on one side of the support plate 2. When the wire cutting mechanism needs to cut the wire, when the electric cylinder 3 drives the wire blocking plate 4 to move to the edge position of the take-up reel, when the wire is cut, the previous take-up reel stops running, and the wire blocking plate 4 blocks the cut wire to prevent it from being carried away by the inertia during the rotation of the take-up reel. The sliding rod 6 is driven to move by the push plate 5, and the sliding rod 6 drives the buffer 7 to move, so that the buffer 7 drives the wire clamping plate 8 to move towards the direction close to the take-up reel. Then, under the extrusion action of the wire clamping plate 8, the wire head is pressed. The wire head is located outside the reel, leaving the wire head for the next process to use.
[0022] Embodiment 2: On the basis of Embodiment 1, the electric cylinder 3 is fixedly installed on the support plate 2. The output end of the electric cylinder 3 penetrates through the support plate 2 and is fixedly connected with one side of the wire blocking plate 4. One side of the electric cylinder 3 is fixedly installed on the support plate 2 to support the electric cylinder 3. Through the telescopic movement of the output end of the electric cylinder 3, the wire blocking plate 4 is driven to move. The wire blocking plate 4 blocks the cut wire head to prevent it from flying around. A limiting hole 9 is opened on the upper surface of the wire blocking plate 4, and the limiting hole 9 is slidably connected with the sliding rod 6. A groove 10 is opened on the lower surface of the wire blocking plate 4, and the groove 10 is slidably connected with the side wall of the wire clamping plate 8. The limiting hole 9 opened on the upper surface of the wire blocking plate 4 limits the sliding rod 6, and the groove 10 opened on the lower surface of the wire blocking plate 4 limits the wire clamping plate 8, so as to facilitate the buffering of the wire clamping plate 8.
[0023] The electric cylinder 3 is electrically connected to an external terminal control device. When the wire is about to be wound from the previous take-up reel to another take-up reel, by controlling the output end of the electric cylinder 3 to extend, the wire blocking plate 4 is driven to move to the edge position of the take-up reel. At this time, the wire is cut by the wire cutting mechanism, and the previous take-up reel stops running. Under the action of inertia, the take-up reel drives the cut wire head to rotate. Thus, under the blocking action of the wire blocking plate 4, the wire head will not fly out, which is convenient for clamping the wire head. The limiting hole 9 opened on the surface of the wire blocking plate 4 limits the sliding rod 6, which facilitates the stability of the sliding of the sliding rod 6 and also increases the stability of the movement of the wire clamping plate 8. The groove 10 opened on the lower surface of the wire blocking plate 4 facilitates the buffering of the wire blocking plate 4.
[0024] Embodiment 3: On the basis of Embodiment 2, fixing frames 11 are fixedly connected to both sides of the wire baffle 4. The two sides of the push plate 5 are slidably connected to the fixing frames 11. The fixing frames 11 are fixedly installed on both sides of the wire baffle 4, so that the fixing frames 11 limit the push plate 5 during the sliding process. A connecting seat 12 is fixedly connected to the upper surface of the push plate 5. A threaded rod 13 is arranged above the connecting seat 12. Both ends of the threaded rod 13 are rotatably sleeved on the top of the fixing frame 11. A threaded sleeve 14 is sleeved on the threaded rod 13. The connecting seat 12 is fixedly installed on the upper surface of the push plate 5 and is arranged symmetrically in pairs. The fixing frame 11 stably supports the threaded rod 13. By rotating the threaded rod 13, the threaded sleeve 14 is driven to move. One end of the connecting rod 15 is rotatably connected to the threaded sleeve 14 through a pin shaft 16, and the other end of the connecting rod 15 is rotatably connected to the connecting seat 12 through a pin shaft 16. A motor 17 is fixedly installed on one side of one of the fixing frames 11. The output end of the motor 17 is fixedly connected to one end of the threaded rod 13. The connecting rod 15 is arranged between the threaded sleeve 14 and the connecting seat 12 and is driven through a pin shaft 16. The motor 17 is fixedly installed on one side of a fixing frame 11, and the output end of the motor 17 is fixedly connected to one end of the threaded rod 13.
[0025] When it is necessary to clamp the wire head, the motor 17 is electrically connected to an external terminal control device. The motor 17 is started. The motor 17 drives the threaded rod 13 fixedly connected to its output end to rotate. Under the rotation of the threaded rod 13, the threaded sleeve 14 sleeved thereon is driven to rotate. One end of the connecting rod 15 is driven to move through the connection of the pin shaft 16 by the threaded sleeve 14. Thus, the other end of the connecting rod 15 drives the connecting seat 12 to move through the connection of the pin shaft 16, so that the connecting seat 12 drives the push plate 5 to move. When the threaded rod 13 drives the two threaded sleeves 14 to move towards each other, at this time, the push plate 5 is indirectly driven to move obliquely downward. Thus, the push plate 5 drives the buffer 7 to move through the connection with the slide bar 6. The buffer 7 further drives the wire clamping plate 8 to move towards the direction close to the wire reel until the wire clamping plate 8 clamps the wire head, and the wire head is clamped between the wire clamping plate 8 and the wire reel.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
