Description

Technical Field

[0001] The utility model relates to the field of wire drawing processes of metal wires, and particularly to a wire drawing tensioning device for low-disturbance ultra-fine wires. Background Art

[0002] In the prior art, tension adjustment is usually carried out by using the weight of a counterweight. However, for ultra-fine wires, this method has low control accuracy and is difficult to overcome the influence of the self-weight and inertia of the structure. During wire drawing, large disturbances will lead to unstable drawing forces, and the drawing stress on the metal wire in the die will change sharply. Especially for ultra-fine wires, it is easy to exceed their yield limit, increasing the risk of wire breakage. A refractory metal wire hot drawing device and its process described in the patent document CN118417348A include a lubrication mechanism, a heating mechanism, a drawing mechanism, and a winding mechanism. The lubrication mechanism, the heating mechanism, the drawing mechanism, and the winding mechanism can form a set of drawing devices. The wire passes through each part of the drawing device in cooperation to ensure that the take-up assembly can take up the wire in a constant-tension manner. The wire drawing dies are arranged in series to ensure that the volume flow per second between each drawing device is equal. There is little friction between the wire and the guide wheels, achieving efficient non-slip wire drawing. However, this patent does not consider the precise control of ultra-fine wires and does not consider maintaining a constant tension during the wire drawing process. If the metal wire twists during wire drawing or take-up, it may also cause the metal wire to knot or deform, affecting the quality of the finished product. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a wire drawing tensioning device for low-disturbance ultra-fine wires, which solves the problems that the tension of ultra-fine metal wires is difficult to accurately regulate during wire drawing and large disturbances lead to poor drawing quality.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a wire drawing tensioning device for low-disturbance ultra-fine wires, including a tension adjustment device arranged between the original wire roller and the take-up device. The tension adjustment device includes a tension adjustment wheel arranged below the metal wire. One side of the tension adjustment wheel is connected with an adjustment rod. A permanent magnet is arranged inside the adjustment rod, and multiple groups of electromagnetic coils are arranged outside the permanent magnet. The tension of the metal wire is adjusted by adjusting the input power of the electromagnetic coils.

[0005] In a preferred solution, a first limit wheel and a second limit wheel are sequentially arranged above the tension adjustment wheel, and the metal wire passes below the first limit wheel and the second limit wheel and above the tension adjustment wheel.

[0006] In a preferred solution, a guide wheel is arranged between the tension adjustment device and the take-up device. The guide wheel and the take-up device are arranged in a staggered manner for obliquely guiding the movement of the metal wire.

[0007] In a preferred embodiment, the positions of the wire guide pulley and the wire take-up device are such that the wire is bent in opposite directions, controlling the torsion of the wire during the wire take-up process.

A permanent magnet is arranged inside the adjustment rod, and a plurality of electromagnetic coils are arranged around the permanent magnet.

Detailed implementation mode

[0018] Embodiment 1:

[0019] As Figures 1 to 3 shown, a wire drawing tensioning device for low-disturbance ultra-fine wires includes a tension adjustment device 5 arranged between the original wire roller 1 and the wire take-up device 4. The tension adjustment device 5 includes a tension adjustment wheel 53 arranged below the wire 2. One side of the tension adjustment wheel 53 is connected with an adjustment rod 54. The adjustment rod 54 is internally provided with a permanent magnet 56, and a plurality of groups of electromagnetic coils 55 are arranged on the periphery of the permanent magnet 56. The tension on the wire 2 is adjusted by adjusting the input power of the electromagnetic coils 55. With this structure, the tension of the tension adjustment wheel 53 is adjusted according to the material and diameter of the wire 2. By adjusting the input power of the electromagnetic coils 55, the tension on the wire 2 is adjusted without being affected by gravity and inertia. In this embodiment, by using the electromagnetic force to control the tension below the wire 2, the tension can be accurately adjusted, especially for the tiny tension of the ultra-fine wire 2, avoiding the problem of poor drawing quality caused by the influence of the self-weight and inertia of the structural parts, ensuring a stable tension level throughout the wire drawing process, and achieving the purpose of low disturbance.

[0020] In a preferred solution, as Figure 1 and 2 shown, a first limit wheel 51 and a second limit wheel 52 are sequentially arranged above the tension adjustment wheel 53, and the wire 2 passes below the first limit wheel 51 and the second limit wheel 52 and above the tension adjustment wheel 53. With this structure, the tension adjustment wheel 53, the first limit wheel 51 and the second limit wheel 52 are used to guide the wire 2 to ensure that it can move along the predetermined path direction during the wire drawing process, further reducing the disturbance influence.

[0021] In a preferred solution, as Figure 1 and 3As shown, a wire guide pulley 3 is provided between the tension adjusting device 5 and the wire take-up device 4. The wire guide pulley 3 and the wire take-up device 4 are arranged in a staggered manner to obliquely guide the movement of the wire 2. With this structure, the height of the wire guide pulley 3 is greater than that of the wire take-up device 4, that is, the centers of the wire guide pulley 3 and the wire take-up device 4 are not on the same horizontal line. The staggered difference between the wire guide pulley 3 and the wire take-up device 4 forms a downward-sloping path to guide the movement of the wire 2, so as to adjust the slackness of the wire 2, guide the wire 2 to be evenly wound during the wire take-up process, and prevent deviation from the track or entanglement. The tension of the wire 2 during the wire take-up process can also be controlled by adjusting the position of the wire guide pulley 3, so that the wire 2 maintains a stable shape and size.

[0022] In a preferred embodiment, as Figure 1 and 3 shown, the positions of the wire guide pulley 3 and the wire take-up device 4 cause the wire 2 to be bent in opposite directions to control the torsion of the wire 2 during the wire take-up process. With this structure, the wire 2 is guided from the horizontal direction to the vertical direction by the wire guide pulley 3 to form the first bend, and then moves along the path direction into the wire take-up device 4 in the opposite direction. The wire take-up device 4 then guides the wire 2 from the vertical direction to the horizontal direction, causing the wire 2 to undergo a second bend in the opposite direction. The two bends in different directions are used to adjust the bending angle and torsion direction of the wire 2, wind the wire 2 onto the wire take-up device 4, thereby eliminating or reducing the torsion effect, preventing the wire 2 from breaking or deforming during the wire take-up process, maintaining the straightness of the wire 2, and reducing the influence of the necessary bending direction during the processing on the finished product.

[0023] In a preferred embodiment, as Figure 1 and 3As shown, the wire take-up device 4 includes a wire take-up wheel 46 and a transmission mechanism connecting the wire take-up wheel 46. The transmission mechanism is connected to a plurality of driving mechanisms. The transmission mechanism includes a transmission rod 45 connecting the wire take-up wheel 46. One end of the transmission rod 45 is provided with a driving wheel 42. Outside the driving wheel 42, there is a driven wheel 41. The driven wheel 41 is in transmission connection with the driving mechanism. The driving mechanism includes a plurality of speed reducers 43. One end of the speed reducer 43 is connected to the transmission mechanism, and the other end is connected to a wire take-up motor 44. The wire take-up motor 44 is used to drive the speed reducer 43. With this structure, the rotation of the transmission mechanism is transmitted through the driving mechanism, and the transmission mechanism drives the wire take-up wheel 46 to wind the wire 2. Through the coordinated control of the tension adjustment device 5 and the wire take-up device 4, the tension of the tension adjustment wheel 53 and the rotation speed of the wire take-up wheel 46 are adjusted to precisely control the tension of the wire 2 during the wire drawing process. The wire take-up wheel 46 is connected to a plurality of driving mechanisms through the transmission mechanism. The driving mechanism includes a plurality of speed reducers 43 with different transmission ratios and wire take-up motors 44 with different powers to achieve a larger adjustable range of speed and torque. The wire take-up device 4 can output combinations of different rotation speeds and different torques to adapt to different processing diameters of the wire 2 and the working conditions of the diameter difference before and after processing, greatly improving the applicability of the device in ultra-fine wires.

[0024] In a preferred embodiment, the wire guide wheel 3 and the wire take-up wheel 46 have the same diameter and are both greater than 10 cm. With this structure, it is ensured that the wire 2 is bent twice at the same angular value but in different angular directions, so that the wire 2 cancels out torsion when passing through the wire guide wheel 3 and the wire take-up device 4, reducing potential damage.

[0025] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
