Description

Technical Field

[0001] This utility model relates to the field of wire drawing equipment technology, specifically a wire clamping device for a wire drawing machine. Background Technology

[0002] The wire clamping device of a wire drawing machine is a device used at the wire exit of the wire drawing machine. Its function is to effectively clamp the metal wire after the take-up reel of the wire drawing machine is full, thereby preventing the metal wire from slipping off the guide wheel.

[0003] Existing wire clamping devices generally cannot thread metal wires of different diameters, thus reducing the application range of wire clamping devices in wire drawing machines. Furthermore, they do not clamp the metal wires securely enough, making it easy for the metal wires to bend.

[0004] As disclosed in CN216501564U, a wire clamping device for a wire drawing machine has two guide rollers in the guide wire mechanism connected to a first lifting rod. When the metal wire is guided through the wire inlet to the space between the two guide rollers, a hydraulic cylinder is activated to adjust the distance between the upper and lower guide rollers to match the outer diameter of the metal wire, thereby guiding metal wires of different sizes. The entire process is convenient to operate and the wire is stable. This not only improves the scope of application of the device but also enhances its practicality. The operator can use the controller to adjust the guide wire mechanism, which is simple and quick, saving labor time and costs, thereby improving the working efficiency of the device.

[0005] However, during the movement of the metal wire, the wire swings irregularly, causing it to continuously "beat" the surface of the guide roller, thus affecting the service life of the guide roller.

[0006] Therefore, we urgently need to provide a wire clamping device for wire drawing machines. Utility Model Content

[0007] The purpose of this invention is to provide a wire clamping device for a wire drawing machine to solve the problem mentioned in the background art where irregular oscillation of the metal wire during its movement causes the wire to continuously "beat" the surface of the guide roller, thus affecting the service life of the guide roller.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wire clamping device for a wire drawing machine, comprising a housing, a wire inlet and a wire outlet, wherein the wire inlet is installed on the left side of the housing and the wire outlet is installed on the right side of the housing, and a wire clamping device is provided inside the housing, the wire clamping device comprising an anti-sway unit, a guide unit and a wire clamping unit.

[0009] The anti-sway unit is located on the left side inside the box, the guide unit is located in the middle inside the box, and the wire clamping unit is located on the right side inside the box.

[0010] The anti-sway unit includes a motor, a threaded rod, a moving block, a limiting rod, a top plate, a support rod, and a cylinder. The motor is fixedly installed on the left side of the back of the housing. One end of the threaded rod is fixedly installed at the output end of the motor. The moving block is threadedly connected to the outer surface of the threaded rod. The limiting rod is fixedly installed inside the housing at the upper end of the threaded rod. The top plate is fixedly installed on the top of the moving block. The support rod is fixedly installed on the top of the top plate. The cylinder is fixedly installed on the top of the support rod.

[0011] Preferably, the guide unit includes an upright plate, a lower guide roller, a telescopic component, a connecting plate, a side plate, and an upper guide roller. The upright plate is fixedly installed on the front and rear sides inside the housing. The lower guide roller is fixedly installed on the lower end of one of the adjacent sides of the two upright plates. The telescopic component is fixedly installed in the middle of the top of the housing. The connecting plate is fixedly installed at the bottom of the telescopic component. The side plate is fixedly installed on the front and rear sides of the bottom of the connecting plate. The upper guide roller is rotatably connected to one of the adjacent sides of the two side plates.

[0012] Preferably, the wire clamping unit includes a second telescopic component, a first clamping tooth, and a second clamping tooth. The second telescopic component is fixedly installed on the top right side of the box body, the first clamping tooth is fixedly installed on the bottom of the second telescopic component, and the second clamping tooth is fixedly installed inside the bottom of the box body, directly below the first clamping tooth.

[0013] Preferably, a limiting hole is provided inside the movable block, and the limiting rod passes through the limiting hole. When the threaded rod is threadedly connected to the movable block, the limiting rod limits the movement of the movable block, allowing the movable block to move back and forth along the limiting rod.

[0014] Preferably, a sliding groove is provided on the upper end of one side of the two adjacent upright plates. The front and rear ends of the upper guide roller are slidably connected in the sliding groove. The sliding groove guides the movement of the upper guide roller, allowing the upper guide roller to move up and down along the sliding groove, thereby realizing the adjustment of the distance between the upper guide roller and the lower guide roller.

[0015] Preferably, the wire inlet and wire outlet have the same shape, and the diameter of the left side is larger than that of the right side, which facilitates the threading of the metal wire.

[0016] Preferably, there are multiple cylinders, and the inner diameter of the cylinders decreases from front to back. By setting multiple cylinders with different inner diameters, it is convenient for metal wires of different diameters to pass through the cylinders.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This wire drawing machine uses a wire clamping device. By setting an anti-sway unit, a cylinder with a suitable inner diameter is rotated according to the diameter of the metal wire. The motor drives the threaded rod to rotate. When the threaded rod rotates, it is threadedly connected to the moving block, thereby causing the moving block to move the cylinder back and forth along the limiting rod. The cylinder is moved to the required position so that it is on the same straight line as the wire inlet. Then the metal wire is passed through the cylinder. When the metal wire moves, the cylinder limits the metal wire, thereby preventing the metal wire from swaying. This solves the problem mentioned in the background technology that the metal wire sways irregularly during the movement of the metal wire, causing the metal wire to continuously "beat" the surface of the guide roller, thus affecting the service life of the guide roller.

[0019] 2. The wire drawing machine uses a wire clamping device. By setting a guide unit, the telescopic component is activated to drive the upper guide roller to move downward, so that the upper guide roller and the lower guide roller cooperate to press the metal wire tightly, thereby guiding the metal wire to move forward.

[0038] In use, the appropriate inner diameter cylinder 407 is rotated according to the diameter of the metal wire. The motor 401 is started to drive the threaded rod 402 to rotate. When the threaded rod 402 rotates, it is threadedly connected to the moving block 403, so that the moving block 403 drives the cylinder 407 to move back and forth along the limit rod 404. The cylinder 407 is moved to the desired position and is aligned with the wire inlet 2. Then, the metal wire is passed through the wire inlet 2, the cylinder 407, and between the lower guide roller 502 and the upper guide roller 506, and then out of the wire outlet 3. Then, the telescopic component 503 is activated to drive the upper guide roller 506 to move down, so that the upper guide roller 506 and the lower guide roller 502 cooperate to press the metal wire, thereby guiding the metal wire to move.
