Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.
[0025] A multi-wire cutting and winding machine, such as Figure 1 As shown, it includes a frame assembly 1, a winding assembly 2, and a take-up and unwinding assembly 3.
[0026] Specifically, such as Figures 1 to 4As shown, the frame assembly includes two bearing housings 11 and two upright plates 12. The two bearing housings 11 are spaced apart, and the two upright plates 12 are spaced apart on the side of one bearing housing 11 facing away from the other bearing housing 11. The winding assembly 2 includes a wire guide wheel mechanism 21, a tension wheel mechanism 22, and a wire feed wheel mechanism 23. The wire guide wheel mechanism 21, the tension wheel mechanism 22, and the take-up and unload assembly 3 are mounted on the upright plates 12. The take-up and unload assembly 3 is located below the wire guide wheel mechanism 21, and the tension wheel mechanism 22 is located above the wire guide wheel mechanism 23. The end of the structure 21 away from the bearing housing 11, the wire guide wheel mechanism 23 is located between the two bearing housings 11, and the take-up and release assembly 3 is connected to the wire guide wheel mechanism 21, the tension wheel mechanism 22 and the wire guide wheel mechanism 23 through the diamond wire 4; the take-up and release assembly 3 is used to take up and release the diamond wire 4, the wire guide wheel mechanism 21 is used to adjust the exit position of the diamond wire 4, the tension wheel mechanism 22 is used to adjust the tension of the diamond wire 4, and the wire guide wheel mechanism 23 is used to adjust the relative position of the diamond wire 4 entering the bearing housing 11. By spacing the two bearing housings 11 and the two upright plates 12, the overall rigidity is ensured (to resist vibration and load during the winding process), and the maintenance process of key components is simplified. The two upright plates 12 are fixed on the same side of the bearing housings 11 to form a stable support frame. The take-up and undo assembly 3 is set below the wire guide wheel mechanism 21. Gravity assists the natural take-up of the diamond wire 4, reducing mechanical resistance, shortening the wire path, and reducing energy consumption and friction loss. Through the coordinated operation of the take-up and undo assembly 3, the wire guide wheel mechanism 21, the tension wheel mechanism 22, and the wire guide wheel mechanism 23, the cutting accuracy and the utilization rate of the diamond wire 4 are improved.
[0027] It is understandable that, since the take-up and release components 3 are set relative to each other, the two take-up and release components 3 can take up and release the wire for each other.
[0028] Specifically, the take-up and unwind assembly 3 includes a base 31 and a first motor 32 mounted on the base 31. A rotating wheel 33 is fitted onto the output end of the first motor 32, and a diamond wire 4 is mounted on the rotating wheel 33. The base 31 also has a support rail 34 that abuts against the rotating wheel 33. The first motor 32 drives the rotating wheel 33 to rotate, thereby driving the diamond wire 4 to take up / unwind. The support rail 34 provides effective support for the rotating wheel 33.
[0029] Specifically, the wire guide mechanism 21 includes a wire laying unit 211 and a wire guide wheel unit 212 respectively disposed on opposite sides of the upright plate 12. The wire laying unit 211 includes a bracket 2111, a second motor 2112, a ball screw 2113, and a slider 2114. The second motor 2112 is disposed on the bracket 2111 fixed to the upright plate 12. The output end of the second motor 2112 is connected to the ball screw 2113. The slider 2114 is threadedly connected to the ball screw 2113 through a ball nut seat 2115. Two guide rails 2116 are provided on one end of the bracket 2111 near the upright plate 12. The end of the slider 2114 away from the ball nut seat 2115 is slidably connected to the guide rails 2116. The end of the slider 2114 away from the ball nut seat 2115 passes through the upright plate 12 and is connected to the wire guide wheel unit 212. The second motor 2112 drives the ball screw 2113 to rotate, thereby causing the slider 2114 connected to the ball nut seat 2115 to slide on the two guide rails 2116, thus changing the relative position of the guide wheel unit 212 connected to the slider 2114.
[0030] Specifically, the guide wheel unit 212 includes a support arm 2121, a fixed plate 2122, a guide wheel 2123, and a balance block 2124. The fixed plate 2122 is connected to the slider 2114. The side of the fixed plate 2122 away from the slider 2114 is connected to the support arm 2121 via a balance pin 2125. The end of the support arm 2121 away from the balance pin 2125 is connected to the guide wheel 2123, and the end of the support arm 2121 away from the guide wheel 2123 is connected to the balance block 2124. The slider 2114 drives the fixed plate 2122, which in turn drives the relative position of the support arm 2121, thereby changing the relative position of the guide wheel 2123 connected to the support arm 2121. To prevent the center of gravity of the support arm 2121 from becoming unbalanced after the relative position of the guide wheel 2123 changes, a balance block 2124 is installed at the end of the support arm 2121 away from the guide wheel 2123.
[0031] Specifically, the tension wheel mechanism 22 includes a third motor 221, a tension arm 222, a tension wheel 223, and limiting posts 224. The third motor 221 is mounted on the upright plate 12. The output shaft of the third motor 221 is connected to one end of the tension arm 222, and the other end of the tension arm 222 is movably connected to the tension wheel 223 via a bearing (not shown). Two limiting posts 224 are provided on the upright plate 12, adjacent to the tension arm 222. The limiting posts 224 are used to limit the movement range of the tension arm 222. A tension sensor 225 is provided on the side of the tension arm 222 facing away from the tension wheel 223. The tension arm 222 is driven to rotate by the third motor 221, thereby driving the tension wheel 223 to change its relative position. The limiting posts 224 limit the movement range of the tension arm 222. During the rotation of the tension wheel 223, the tension sensor 225 detects the tension of the diamond wire 4 on the tension wheel in real time.
[0032] Specifically, the cable routing mechanism 23 includes a support rod 231, a movable connecting block 232, and a cable routing wheel 233. The two ends of the support rod 231 are connected to two bearing housings 11 respectively. The cable routing wheel 233 is connected to the support rod 231 via the movable connecting block 232. The angle between the bottom of the cable routing wheel 233 and the parallel line to the ground is 22.6°. By changing the position of the movable connecting block 232 on the support rod, the cable routing wheel 233 is positioned on the tangent line of the inlet / outlet end of the grooved wheel 111, and the angle between the bottom of the cable routing wheel 233 and the parallel line to the ground is 22.6°. This ensures the proper routing position of the diamond wire 4 on the cable routing wheel 233 and the grooved wheel 111, reducing the tangling and crossing of the diamond wire 4.
[0033] Specifically, the guide wheel 2123, tension wheel 223, and guide wheel 233 all include a center wheel 21231 and a sleeve 21232 fitted around the periphery of the center wheel 21231. The sleeve 21232 has a groove that fits the diamond wire 4. The center wheels of the guide wheel 2123, tension wheel 223, and guide wheel 233 have the same diameter. The top height of the guide wheel 2123 is the same as the bottom height of the tension wheel 223, and the top height of the tension wheel 223 is the same as the top height of the guide wheel 233. By setting a sleeve 21232 on the central wheel 21231, the sleeve 21232 directly contacts the diamond wire 4. The sleeve 21232 can be replaced after wear, reducing the process and cost of the entire wheel. Compared with the existing technology, it reduces the number of wheel sets used, making the operation convenient and efficient, and reducing the equipment manufacturing cost. The complete path of the diamond wire is: rotating wheel 33 - wire guide wheel 2123 - tension wheel 223 - through hole 121 - wire guide wheel 233 - groove wheel 111 inlet end - groove wheel 111 outlet end - wire guide wheel 233 - through hole 121 - tension wheel 223 - wire guide wheel 2123 - rotating wheel 33. The top height of the wire guide wheel 2123 is the same as the bottom height of the tension wheel 223, and the top height of the tension wheel 223 is the same as the top height of the wire guide wheel 233, which reduces the possibility of the diamond wire 4 winding and reduces the risk of breakage and machine downtime.
[0034] Specifically, a grooved wheel 111 is movably connected between the two bearing housings 11. A wire guide wheel is located above the grooved wheel 111, and the wire guide wheel is positioned on the tangent of the wire output end of the grooved wheel 111. A lifting assembly is located above the grooved wheel 111, which is used to drive the crystal rod to move. A through hole 121 is provided on the upright plate 12, which is used to pass through the diamond wire 4. The diamond wire 4 is arranged in an intermittent winding pattern on the grooved wheel 111. The crystal rod moves up and down through the lifting assembly 112, thereby shaping the crystal rod into a preset size. The two wire guide wheels 233 are arranged diagonally, and the wire guide wheels 233 are positioned on the tangent of the wire output end of the grooved wheel 111, so that the wires of the diamond wire 4 fill the grooved wheel 111, while also preventing the diamond wire 4 from tangling or crossing.
[0035] This invention achieves precise control of the diamond wire 4 through the linkage control of the take-up and release assembly 3 and the winding assembly 2: First, the take-up and release assembly 3 releases the diamond wire 4; second, the wire guide wheel mechanism 21 performs wire exit posture calibration to eliminate multi-wire entanglement and cross interference, maintaining the consistency of the winding trajectory; then, the tension wheel mechanism 22 achieves dynamic tension control, compensating in real time for the risk of wire breakage and cutting surface quality defects caused by tension fluctuations; finally, the wire guide wheel mechanism 23 performs multi-dimensional position calibration to adapt to diverse wire spacing parameters and irregular cutting path planning; through the dynamic compensation of the tension wheel mechanism 22 and the precise guidance of the wire guide wheel mechanism 21 and the wire guide wheel mechanism 23, abnormal frictional loss between the diamond wire 4 and the transmission mechanism is effectively suppressed, systematically reducing the wire breakage rate and the transmission mechanism loss rate, significantly improving cutting accuracy and wire utilization, and thus effectively improving the equipment's uptime.
