AI Technical Summary
The existing double-inner core wire drawing machine uses wire drawing machines to control the tension unstable when retracting, resulting in uneven wire retracting of wire, affecting the appearance quality and dimensional accuracy of the product, and increasing the risk of breaking during subsequent processing.
A double inner core wire drawing machine is designed, using an automatic adjustment tension adjustment wheel and a moving through-ring structure. When the wire tension is too high, the downward pressure of the tension adjusting wheel reduces the tension force; when the tension is too low, the upward movement increases the tension force. The moving through ring and the moving block drive the front and back movement through the servo motor, dynamically adjusting the position of the wire on the retracting wheel to ensure uniform retracting.
By automatically adjusting the tension and dynamically adjusting the wire position, the uniformity of the wire is improved, the local accumulation or sparseness of the wire on the wire retracting wheel is reduced, the appearance quality and dimensional accuracy of the product are improved, the risk of wire breaking is reduced, and the product yield is guaranteed.

Technical Field
[0001] The utility model relates to the technical field of double inner core wire processing, in particular to a wire drawing machine for double inner core wire. Background Art
[0002] A wire drawing machine is a mechanical device that applies traction to make metal materials (such as steel wire, aluminum wire, etc.) pass through a series of dies or rollers to undergo plastic deformation to achieve the required diameter and size. A double-core wire drawing machine is a mechanical device specifically used to stretch and refine metal wires with a double-core structure.
[0003] When the existing double-inner-core wire drawing machine is winding up after drawing, the tension of the double-inner-core wire is easily uncontrolled, resulting in uneven force on the double-inner-core wire during winding up, thereby affecting its uniformity. Uneven winding up will cause the wire to accumulate or become sparse on the winding wheel, thereby affecting the appearance quality and dimensional accuracy of the product. Uneven winding up also increases the risk of wire breakage in subsequent processing, reducing the product's yield rate. Utility Model Content

DETAILED DESCRIPTION
[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.
[0020] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0021] This embodiment mainly describes a wire drawing machine for double inner core wires, as follows:
[0022] like Figure 1-4As shown, a wire drawing machine for double inner core wires includes a base 1 and a pay-off wheel 2, a fixed plate 3 is fixedly installed on the upper end of the base 1, a take-up wheel 4 is movably connected to the right side of the front end of the fixed plate 3, the pay-off wheel 2 is movably connected to the left side of the upper end of the base 1, and a traction wheel 5 is movably connected to the left side of the upper end of the base 1, an adjustment mechanism 6 is arranged on the left side of the front end of the fixed plate 3, a first guide wheel 7 is fixedly installed on the left side of the front end of the adjustment mechanism 6, and a second guide wheel 8 is fixedly installed on the right side of the front end of the adjustment mechanism 6, a driving assembly 9 is arranged on the front end of the fixed plate 3, and an adjustment plate 10 is fixedly installed on the front end of the driving assembly 9, and the adjustment plate 10 and the fixed plate 3 are connected to each other. The plates 3 maintain a parallel position relationship, a tension adjusting wheel 11 is fixedly installed on the left side of the front end of the adjustment plate 10, a fixed concave plate 12 is fixedly installed on the front end of the fixed plate 3, an adjustment mechanism 13 is arranged inside the fixed concave plate 12, a moving block 14 is threadedly connected to the outer surface of the adjustment mechanism 13, a moving ring 15 is fixedly installed on the upper end of the moving block 14, the moving block 14 and the moving ring 15 are located on the left side of the take-up wheel 4, the wire is located on the pay-off wheel 2, and the wire is discharged and contacted with the traction wheel 5 when the pay-off wheel 2 rotates, and the rotation of the traction wheel 5 applies tension to the wire material to cause plastic deformation. During the drawing process, the wire material will undergo grain deformation and slippage, thereby changing its shape and size. After drawing, the wire first contacts the outer surface of the first guide wheel 7, and then the wire is located on the lower surface of the tension adjustment wheel 11, and then contacts the upper surface of the second guide wheel 8. The first guide wheel 7 and the second guide wheel 8 guide the wire, so that the wire can be accurately collected after drawing. By setting the height position of the tension adjustment wheel 11, when the wire tension is too large, the tension adjustment wheel 11 will be pressed down appropriately to reduce the pulling force on the wire and prevent the wire from being broken or over-stretched. On the contrary, when the wire tension is too small, the tension adjustment wheel 11 will move up to increase the pulling force on the wire, ensuring that the wire can be tightly and evenly wound on the take-up wheel 4. This automatic adjustment function helps to improve the uniformity of wire collection and reduce accumulation and sparseness. By adjusting the position of the moving block 14 and the moving ring 15 to make them reciprocate back and forth, the wire can be driven to move back and forth. The double inner core wire moves back and forth during the wire collection process, and its position on the wire collection wheel 4 can be dynamically adjusted, so that the wire can be more evenly distributed on the wire collection wheel 4. This dynamic adjustment helps to reduce the local accumulation or sparseness of the wire on the wire collection wheel 4, improve the uniformity of wire collection, ensure the appearance quality and dimensional accuracy of the product, prevent the risk of wire breakage in the subsequent processing process, and ensure the product yield.
[0023] A support leg 16 is fixedly installed at each of the four corners of the lower end of the base 1 , and the support leg 16 plays a supporting role for the base 1 .
[0024] like Figure 2As shown, the adjustment mechanism 6 includes a first servo motor 61, a rotating shaft 62 is fixedly installed at the output end of the first servo motor 61, an adjustment plate 63 is fixedly installed at the front end of the rotating shaft 62, the first servo motor 61 is fixedly connected to the rear end of the fixed plate 3, and the first guide wheel 7 and the second guide wheel 8 are fixedly connected to the front end of the adjustment plate 63.
[0025] like Figure 3 As shown, the driving assembly 9 includes a second servo motor 91, and a driving shaft 92 is fixedly installed at the output end of the second servo motor 91. The second servo motor 91 is fixedly connected to the rear end of the fixed plate 3, and the driving shaft 92 and the adjustment plate 10 are fixedly connected. The second servo motor 91 drives the driving shaft 92 to rotate, thereby driving the adjustment plate 10 to rotate to adjust the height position of the tension adjustment wheel 11, thereby ensuring that the wire can be tightly and evenly wound around the take-up wheel 4.
[0026] like Figure 4 As shown, the adjustment mechanism 13 includes a third servo motor 131, and a screw rod 132 is fixedly installed at the output end of the third servo motor 131. The third servo motor 131 is fixedly connected to the front end of the fixed concave plate 12, and the moving block 14 is threadedly connected to the screw rod 132. The screw rod 132 is driven to rotate by the third servo motor 131, thereby driving the moving block 14 and the moving ring 15 to reciprocate back and forth along the screw rod 132, thereby driving the wire to move back and forth, so as to facilitate the adjustment of the position of the wire and thus facilitate the uniform winding of the wire after drawing onto the winding wheel 4.
[0027] When in use, the wire is located on the pay-off wheel 2, and the wire is discharged and contacted with the traction wheel 5 by the rotation of the pay-off wheel 2. The rotation of the traction wheel 5 applies tension to the wire material, causing it to undergo plastic deformation. During the stretching process, the wire material will undergo grain deformation and slippage, thereby changing its shape and size. After the wire drawing is completed, the wire first contacts the outer surface of the first guide wheel 7, and then the wire is located on the lower side of the surface of the tension adjustment wheel 11, and then contacts the upper side of the surface of the second guide wheel 8. The first guide wheel 7 and the second guide wheel 8 guide the wire, so that the wire can be accurately collected after the wire drawing is completed. The second servo motor 91 drives the drive shaft 92 to rotate, thereby driving the adjustment plate 10 to rotate to adjust the height position of the tension adjustment wheel 11. When the wire tension is too large, the tension adjustment wheel 11 will be appropriately pressed down to reduce the tension on the wire to prevent the wire from being broken or overstretched. On the contrary, when the wire tension is too small, the tension adjustment wheel 11 will move up to increase the pulling force on the wire, ensuring that the wire can be tightly and evenly wound on the take-up wheel 4. This automatic adjustment function helps to improve the uniformity of wire collection and reduce accumulation and sparseness. The wire passes through the through hole of the moving ring 15 and then contacts the take-up wheel 4 for wire collection. The third servo motor 131 drives the screw rod 132 to rotate, thereby driving the moving block 14 and the moving ring 15 to reciprocate forward and backward along the screw rod 132, thereby driving the wire to move forward and backward. The double inner core wire moves forward and backward during the wire collection process, and its position on the take-up wheel 4 can be dynamically adjusted, so that the wire can be more evenly distributed on the take-up wheel 4. This dynamic adjustment helps to reduce the local accumulation or sparseness of the wire on the take-up wheel 4, improve the uniformity of wire collection, ensure the appearance quality and dimensional accuracy of the product, prevent the risk of wire breakage in subsequent processing, and ensure the yield rate of the product.
