Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, and in particular to a multi-wire cutting machine. Background Technology

[0002] A magnetic material cutting machine is a mechanism used for wire cutting of magnetic materials. It includes a lifting assembly, a roller assembly, and a take-up and unload assembly. The workpiece is placed on the lifting assembly, which moves it towards the roller assembly. The roller assembly, in conjunction with the take-up and unload assembly, has a continuously moving cutting wire wound around it, which cuts the workpiece. In existing designs, for ease of wiring, the two sets of rollers for take-up and unload of the take-up and unload assembly are usually arranged on the same side. This results in overall instability during operation, requiring an additional stabilizing mechanism to maintain balance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-wire cutting machine that can ensure stable operation of the machine body and reduce vibration.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-wire cutting machine, including a roller assembly, a lifting assembly and a take-up and unload assembly, wherein the roller assembly is arranged on the upper side of the lifting assembly, and the take-up and unload assembly includes take-up and unload wheels, with two take-up and unload wheels symmetrically arranged on both sides of the roller assembly.

[0005] Furthermore, it also includes a frame, which includes an upper casting frame and a lower casting frame connected vertically. The roller assembly is arranged inside the upper casting frame, the lifting assembly is arranged inside the lower casting frame, and the two take-up and unwinding reels are arranged on the back side of the lower casting frame.

[0006] Furthermore, the roller assembly includes a first roller, a second roller, a third roller, and a fourth roller, the second roller, the third roller, and the fourth roller are arranged side by side at intervals, and the first roller is arranged on the upper side of the third roller; the first roller, the second roller, and the fourth roller form an equilateral triangle structure after winding.

[0007] Furthermore, the first roller, the second roller, the third roller, and the fourth roller are all provided with grooves, and the grooves of the first roller are staggered with those of the second roller and the fourth roller.

[0008] Furthermore, the take-up and unwind assembly also includes a wire guide wheel, a moving motor, rollers, a connecting seat, and a sensor. The wire guide wheel is arranged on the upper side of the take-up and unwind assembly. The driving end of the moving motor is connected to the wire guide wheel, rollers, connecting seat, and sensor, and drives the wire guide wheel, rollers, connecting seat, and sensor to move along the axial direction of the take-up and unwind assembly. A connecting seat is arranged on the lower side of the wire guide wheel. Two rollers are arranged at intervals on the connecting seat along the axial direction of the take-up and unwind assembly. The rollers are rotatably connected to the connecting seat. The sensor is located on the side of the connecting seat away from the rollers. A trigger element is provided at the end of the roller near the sensor. A sensing element is provided at the end of the sensor corresponding to the end of the roller. The sensing element senses the rotational state of the trigger element. The sensor is electrically connected to the moving motor. The cutting wire on the take-up and release spools passes between the rollers and winds onto the cable tray spool. When the rollers come into contact with the cutting wire on the take-up and release spools, the rollers rotate under the friction of the cutting wire, changing the rotation state of the trigger. The moving motor drives the cable tray spool to move toward the direction of the rollers until the cutting wire no longer comes into contact with the rollers.

[0009] Furthermore, the surface of the cable guide wheel is perpendicular to the cross-section of the take-up and release wheel, and the axial extension line of the roller is inclined to the surface of the cable guide wheel.

One end of the connecting bracket extends axially along the take-up and release reel and is rotatably connected to the line guide reel. The other side of the rotating base is connected to the counterweight. The wheel surface of the line guide reel is perpendicular to the cross-section of the take-up and release reel.

[0011] Furthermore, it also includes a tension wheel and a rotating motor, the drive end of the rotating motor being connected to the tension wheel and the two being arranged eccentrically, and the cutting wire on the take-up and release wheel being wound onto the tension wheel.

[0012] Furthermore, the take-up and unwind assembly also includes an adjusting guide wheel, an adjusting bracket, and a mounting bracket. The mounting bracket is fixedly mounted on the lower side of the roller assembly. The mounting bracket has two clamping blocks with a mounting hole between them and a through-hole threaded through the two clamping blocks. One end of the adjusting bracket is inserted into the mounting hole, and the other end is rotatably connected to the adjusting guide wheel.

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 and Figure 2 A multi-wire cutting machine includes a roller assembly 1, a lifting assembly 2, and a wire take-up and unload assembly 3. The roller assembly 1 is arranged above the lifting assembly 2, and the wire take-up and unload assembly 3 includes two wire take-up and unload reels 31, which are symmetrically arranged on both sides of the roller assembly 1. As can be seen from the above description, the beneficial effect of this invention is that the symmetrical design of the wire take-up and unload reels 31 on both sides of the roller assembly 1 ensures the stability of the equipment during operation and reduces the impact of vibration. Furthermore, as... Figure 2 As shown, it also includes a frame 4, which comprises an upper casting frame 41 and a lower casting frame 42, which are connected vertically. The roller assembly 1 is arranged inside the upper casting frame 41, the lifting assembly 2 is arranged inside the lower casting frame 42, and the two take-up and untake-down reels 31 are arranged on the back side of the lower casting frame 42. As can be seen from the above description, the separate design of the upper casting frame 41 and the lower casting frame 42 facilitates production assembly. Furthermore, as... Figure 3 and Figure 4 As shown, the roller assembly 1 includes a first roller 11, a second roller 12, a third roller 13, and a fourth roller 14. The second roller 12, the third roller 13, and the fourth roller 14 are arranged side by side with intervals, and the first roller 11 is arranged above the third roller 13. The first roller 11, the second roller 12, and the fourth roller 14 form an equilateral triangle structure after winding. As can be seen from the above description, the design of the first roller 11, the second roller 12, the third roller 13, and the fourth roller 14 can reduce the number of rollers compared to the traditional rectangular arrangement, while ensuring stable cutting operations. Furthermore, the first roller 11, the second roller 12, the third roller 13, and the fourth roller 14 are all provided with grooves, and the grooves of the first roller 11 are staggered with the grooves of the second roller 12 and the fourth roller 14. As described above, by staggering the grooves of the first roller 11 with those of the second roller 12 and the fourth roller 14, segmented, smooth skipping of the thread can be achieved, thereby reducing wear on the roller body caused by the cutting wire. Furthermore, as... Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, the take-up and unwind assembly 3 also includes a cable guide wheel 32, a moving motor 33, a roller 34, a connecting seat 35, and a sensor 36. The cable guide wheel 32 is arranged on the upper side of the take-up and unwind wheel 31. The driving end of the moving motor 33 is connected to the cable guide wheel 32, the roller 34, the connecting seat 35, and the sensor 36, and drives the cable guide wheel 32, the roller 34, the connecting seat 35, and the sensor 36 to move along the axial direction of the take-up and unwind wheel 31. A connecting seat 35 is arranged on the lower side of the cable guide wheel 32. The rollers 34 are arranged at intervals along the axial direction of the take-up and untake-down reels 31 on the connecting seat 35. The rollers 34 are rotatably connected to the connecting seat 35. The sensor 36 is located on the side of the connecting seat 35 away from the rollers 34. The end of the roller 34 near the sensor 36 is provided with a trigger element 341. The sensor 36 is provided with a sensing element 361 at the end of the roller 34. The sensing element 361 senses the rotation state of the trigger element 341. The sensor 36 is electrically connected to the moving motor 33. The cutting wire on the take-up and release reel 31 is threaded between the rollers 34 and wound onto the cable tray 32. When the roller 34 comes into contact with the cutting wire on the take-up and release reel 31, the roller 34 rotates under the friction of the cutting wire, changing the rotation state of the trigger 341. The moving motor 33 drives the cable tray 32 to move toward the direction of the roller 34 until the cutting wire no longer comes into contact with the roller 34.

[0018] As described above, when the take-up / reel 31 delivers or retracts the wire, the cutting wire moves axially along the take-up / reel 31. When the cutting wire moves axially along the take-up / reel 31, it comes into contact with the roller 34. This contact pressure causes the roller 34 and its end-mounted trigger 341 to rotate. The sensor 361 on the sensor 36 periodically senses and judges the rotation state of the roller 34 and the trigger 341 at this time. The moving motor 33 then drives the wire guide wheel 32 and the roller 34 to move to match the displacement of the cutting wire, achieving stable take-up / reeling and reducing wear on the take-up / reel assembly 3. Further, as... Figure 5 As shown, the surface of the wire guide wheel 32 is perpendicular to the cross-section of the take-up and untake-up wheel 31, and the axial extension of the roller 34 is inclined to the surface of the wire guide wheel 32. As can be seen from the above description, the arrangement of the surface of the wire guide wheel 32 with the cross-section of the take-up and untake-up wheel 31 and the axial extension of the roller 34 allows the cutting wire guided by the wire guide wheel 32 to be output axially along the take-up and untake-up wheel 31, while the inclined arrangement of the roller 34 relative to the surface of the wire guide wheel 32 reduces wear on the roller 34 during transmission. Furthermore, as... Figure 5As shown, the take-up and release assembly 3 also includes a connecting bracket 37, a rotating seat 38, and a counterweight 39. The rotating seat 38 is rotatably connected to the drive end of the moving motor 33. One side of the rotating seat 38 is connected to the connecting bracket 37. One end of the connecting bracket 37 extends axially along the take-up and release reel 31 and is rotatably connected to the line guide reel 32. The other side of the rotating seat 38 is connected to the counterweight 39. The wheel surface of the line guide reel 32 is perpendicular to the cross-section of the take-up and release reel 31. As described above, since the cutting wire moves axially and also displaces towards both sides of the take-up and undo reel 31 during take-up or undoing, the design incorporates a connecting bracket 37, a rotating seat 38, and a counterweight 39. This allows the wire guide reel 32 to swing towards both sides of the take-up and undo reel 31 to match the displacement of the cutting wire, ensuring stable wire transmission. The counterweight 39 balances the weight of the connecting bracket 37 and the wire guide reel 32, making the structure on both sides of the rotating seat 38 more balanced. When the cutting wire output pulls the wire guide reel 32, causing the rotating seat 38 to wobble, the friction between the cutting wire and the wire guide reel 32 keeps the groove of the wire guide reel 32 aligned with the output direction of the cutting wire, preventing excessive pressure from the cutting wire against the groove of the wire guide reel 32 and potential damage. Furthermore, as... Figure 4 As shown, it also includes a tension wheel 5 and a rotary motor 6. The drive end of the rotary motor 6 is connected to the tension wheel 5, and the two are eccentrically arranged. The cutting wire on the take-up and untake-down reel 31 is wound onto the tension wheel 5. As can be seen from the above description, the tension of the cutting wire is controlled by the cooperation of the tension wheel 5 and the rotary motor 6. Further, as... Figure 4 and Figure 6 As shown, the take-up and unwind assembly 3 also includes an adjusting guide wheel 310, an adjusting bracket 311, and a mounting bracket 312. The mounting bracket 312 is fixedly mounted on the lower side of the roller assembly 1. The mounting bracket 312 has two clamping blocks 3121, with a mounting hole between the clamping blocks 3121 and a through-hole threaded through the two clamping blocks 3121. One end of the adjusting bracket 311 is inserted into the mounting hole, and the other end is rotatably connected to the adjusting guide wheel 310. The cutting wire on the take-up and unwind wheel 31 is wound onto the adjusting guide wheel 310. As can be seen from the above description, when the cutting wire is wound onto the roller assembly 1, its angle also needs to be adjusted to smooth the wire feed and reduce friction. Thus, through the design of the adjusting guide wheel 310, the adjusting bracket 311, and the mounting bracket 312, the output angle of the cutting wire is adjusted by changing the assembly angle of the adjusting bracket 311 on the mounting bracket 312. The adjusting bracket 311 achieves quick disassembly and adjustment through its cooperation with the mounting hole and the clamping block 3121. Further, as Figure 7As shown, the take-up and release assembly 3 also includes a braking structure 313 and a drive motor 314. The drive shaft of the drive motor 314 is sleeved and locked to the take-up and release reel 31. The drive shaft is provided with a socket 3142. The braking structure 313 includes a fixed bracket 3131 and a braking pin 3132. The fixed bracket 3131 is connected to the drive motor 314. The braking pin 3132 is opposite to the axial surface of the drive shaft. The braking pin 3132 is movably disposed on the fixed bracket 3131 and is inserted into the socket 3142. As described above, the take-up and release reel 31 rotates by being locked to the drive shaft of the drive motor 314. In the traditional disassembly and assembly operation, the drive motor 314 needs to be adjusted to a braking state before the locking structure of the take-up and release reel 31 can be easily released and the drive shaft of the drive motor 314 can be disengaged. The operation requires the control design of the drive motor 314. However, in this design, through the design of the socket 3142, the fixed bracket 3131 and the brake pin 3132 on the drive shaft, the brake pin 3132 can be easily inserted into the socket 3142 of the drive shaft when the take-up and release reel 31 needs to be disassembled. The fixed bracket 3131 and the equally fixed drive motor 314 cooperate to achieve quick braking of the drive shaft, and then the take-up and release reel 31 can be quickly disassembled and assembled.

[0019] Example 1: like Figure 1 and Figure 2 As shown, a multi-wire cutting machine includes a frame 4 consisting of an upper casting frame 41 and a lower casting frame 42 connected vertically. This split design greatly facilitates the production and assembly of the equipment. A protective cover is provided on the outside of the frame 4. Inside the frame 4, the roller assembly 1 is arranged within the upper casting frame 41, and the lifting assembly 2 is installed within the lower casting frame 42. A feed inlet and a baffle structure for opening and closing the feed inlet are provided on the front side of the frame 4 corresponding to the lifting assembly 2. The two core take-up and untake-down wheels 31 of the take-up and untake-down assembly 3 are symmetrically arranged on the back side of the lower casting frame 42. This symmetrical layout effectively ensures the stability of the equipment during high-speed cutting operations and significantly reduces the impact of vibration on cutting accuracy.

[0020] The equipment also includes an industrial control system, which is electrically connected to the roller assembly 1, the lifting assembly 2, and the wire take-up and unwinding assembly 3. For example... Figure 3 and Figure 4As shown, the roller assembly 1 specifically comprises a first roller 11, a second roller 12, a third roller 13, and a fourth roller 14. The second roller 12, third roller 13, and fourth roller 14 are arranged side-by-side with intervals, forming two parallel processing stations. A spray structure is also provided above the stations. The first roller 11 is located above the third roller 13. Through winding, the first roller 11, second roller 12, and fourth roller 14 together form a stable equilateral triangle structure. Compared to the traditional rectangular roller arrangement, this design reduces the number of rollers used while still ensuring stable guidance of the cutting line and smooth cutting operation. Furthermore, all rollers have grooves to guide the cutting line, and the grooves of the first roller 11 are staggered with those of the second roller 12 and fourth roller 14. This method achieves segmented, smooth skipping of the cutting line, thereby significantly reducing wear on the roller body caused by the cutting line.

[0021] A wire breakage detection device is also provided on both sides of the roller assembly 1. For example... Figure 4 and Figure 5 As shown, the take-up and unwind assembly 3 also includes a take-up and unwind reel 31, a wire guide reel 32, a moving motor 33, rollers 34, a connecting seat 35, a sensor 36, and a linear motion mechanism. The wire guide reel 32 is located above the take-up and unwind reel 31, and its surface is configured to be perpendicular to the cross-section of the take-up and unwind reel 31 to ensure that the cut wire is output neatly along the axial direction. The wire guide reel 32, rollers 34, connecting seat 35, and sensor 36 are mounted on the linear motion mechanism. The drive end of the moving motor 33 is connected to the linear motion mechanism, and the moving motor 33 can drive the wire guide reel 32, rollers 34, connecting seat 35, and sensor 36 to move as a whole along the axial direction of the take-up and unwind reel 31. A connecting seat 35 is provided on the lower side of the wire guide reel 32, and two rollers 34 are arranged axially spaced on the connecting seat 35. The rollers 34 are rotatably connected to the connecting seat 35, and the sensor 36 is located on the side of the connecting seat 35 away from the rollers 34. Each roller 34 has a trigger element 341 at its end, and the sensor 36 has a corresponding sensing element 361. Specifically, as shown in the figure... Figure 8 and Figure 9As shown, the trigger element 341 consists of multiple trigger plates arranged around the end of the roller 34, shaped like fan blades. The sensor 36 intermittently senses to determine whether the trigger element 341 and its corresponding roller 34 are in a stationary or rotating state, thus providing feedback to the moving motor 33 to initiate an action. When the take-up or undo reel 31 is taking up or undoing wire, the cutting wire may undergo axial displacement and come into contact with the roller 34. This contact force causes the roller 34 in the corresponding direction to rotate, thereby changing the relative position between the trigger element 341 and the sensor 361, allowing the sensor 36 to identify that the roller 34 on that side is rotating. After this change signal is captured by the sensor 36, it is transmitted to the industrial control system, and then, under the control of the program, it is fed back to the moving motor 33 to execute an action. The moving motor 33 then drives the wire guide reel 32, roller 34, connecting seat 35, and sensor 36 to move until the cutting wire is no longer in contact with the roller 34. This sensitive sensing and feedback mechanism can automatically track and match the positional changes of the cutting wire, achieving an extremely stable take-up and undo process and minimizing wear on the components caused by the cutting wire. For further optimization, the axial extension of the roller 34 is designed to be inclined to the surface of the winding wheel 32. This inclination angle effectively reduces wear on the sides of the roller 34 during transmission. To accommodate the displacement of the cutting wire on both sides of the take-up and undo wheels 31, the winding wheel 32 is also designed as a swingable structure. This is achieved through a rotating base 38, which is rotatably connected to the linear motion mechanism. One side of the base is connected to the winding wheel 32 via a connecting bracket 37, and the other side is connected to a counterweight 39. When the cutting wire deviates to one side, the wire guide wheel 32 can swing accordingly to maintain the optimal guiding angle; the counterweight 39 is designed to balance the weight of the connecting bracket 37 and the wire guide wheel 32, making the structure on both sides of the rotating seat 38 more balanced. Thus, when the cutting wire output pulls the wire guide wheel 32, causing the rotating seat 38 to wobble, the friction between the cutting wire and the wire guide wheel 32 keeps the groove of the wire guide wheel 32 aligned with the direction of the cutting wire output, preventing the cutting wire from excessively pressing against the groove of the wire guide wheel 32 and causing damage. Furthermore, as... Figure 4 As shown, it also includes a tension wheel 5 driven by a rotary motor 6, with the drive end and tension wheel 5 arranged eccentrically. The cutting wire passes around the tension wheel 5, and the tension of the entire cutting wire can be precisely adjusted by controlling the rotary motor 6. Figure 4 and Figure 6As shown, an angle adjustment mechanism is also provided at the inlet end of the roller assembly 1. This mechanism consists of an adjusting guide wheel 310, an adjusting bracket 311, and a mounting bracket 312. The mounting bracket 312 is fixed to the lower side of the roller assembly 1 and has two clamping blocks 3121 with mounting holes, as well as screw holes passing through them. One end of the adjusting bracket 311 is inserted into the mounting hole, and the other end is fitted with the adjusting guide wheel 310. The cutting wire passes over the guide wheel. By loosening the bolt in the screw hole, the angle of the adjusting bracket 311 can be easily adjusted, thereby changing the angle at which the cutting wire enters the roller assembly 1, achieving smooth wire feeding and reducing friction. This structure also supports quick disassembly and adjustment. Figure 7 As shown, the drive portion of the take-up / release assembly 3 includes a drive motor 314 and an independent braking structure 313. The drive shaft of the drive motor 314 is fixed to the take-up / release reel 31 by a sleeve locking mechanism, and a socket 3142 is machined on the shaft surface of the drive shaft. In this embodiment, a fixing member is sleeved on the drive shaft, and the socket 3142 is disposed on the fixing member. The braking structure 313 consists of a fixed bracket 3131 and a braking pin 3132. The fixed bracket 3131 is connected to the housing of the drive motor 314, and the braking pin 3132 is movably disposed on the fixed bracket 3131 and faces the drive shaft socket 3142. When the take-up / release reel 31 needs to be disassembled for maintenance or replacement, there is no need to perform a complex electrical braking operation on the drive motor 314. Simply insert the braking pin 3132 manually into the drive shaft socket 3142 to achieve rapid mechanical braking, greatly simplifying the disassembly and assembly process and improving maintenance efficiency.

[0022] In summary, the multi-wire cutting machine provided by this utility model, through the symmetrical design of the wire take-up and take-down wheels on both sides of the roller assembly, can ensure the stability of the equipment during operation and reduce the impact of vibration.
