Description

Technical Field

[0001] The invention relates to the technical field of wire cutting, and in particular to a multi-wire wire cutting machine. Background Art

[0002] Multi-wire cutting is a new cutting method that uses high-speed movement of metal wire to bring abrasives into the processing area for cutting, and cuts hard and brittle materials into hundreds of thin slices at a time. Usually, multi-wire cutting machines are machines that use wire cutting. The wire cutting method mainly uses a roller group to drive the cutting wire to move to achieve cutting. Therefore, the cutting wire is in a taut state during operation. Before wire cutting, it is necessary to manually wind the wire on its cutting mechanism. However, this cutting method usually has the following problems:

[0003] If a difficult-to-cut area is encountered during the cutting process, or the cutting line descends too quickly, the originally horizontal cutting line will be deformed. Therefore, it is necessary to speed up the cutting speed or increase the cutting force. However, the existing wire cutting devices do not have effective improvements and solutions to these problems.

[0004] For this purpose, we designed a multi-wire wire cutting machine. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A multi-wire wire cutting machine comprises a plate to be cut, a bracket and a lower pressure frame that slides symmetrically on the bracket, two positioning rods are horizontally arranged between two adjacent lower pressure frames, and a rotating ring is rotatably sleeved on the positioning rods, a cutting metal wire for cutting the plate to be cut is arranged between the two adjacent positioning rods, and the two ends of the cutting metal wire are respectively fixedly wound around the outer wall of the rotating ring, a guide ring is coaxially sleeved on the rotating ring, and a wire sleeve tube for guiding the cutting metal wire is provided on the guide ring, and a driving part for driving the rotating ring to reciprocate is also provided on the guide ring.

[0008] Preferably, the two rotating rings rotate in the same direction reciprocatingly, the rotating ring rotates coaxially with the guide ring through the bracket ring, the guide ring slides linearly on the positioning rod through the guide rod and the socket, and the guide ring is also provided with a threaded rod for positioning with the positioning rod.

[0009] Preferably, the wire sleeve rotates horizontally on the guide ring through the first rotating disk, and the first rotating disk rotates on the side wall of the guide ring through the circular hole, and a through hole connected to the wire sleeve is provided on the first rotating disk, wherein the cutting metal wire passes through the wire sleeve and the first rotating disk and is wound around the outer wall of the rotating ring.

[0010] Preferably, a sliding tube slides inside the sleeve tube, and an inner wall of the sliding tube is provided with an inclined surface. A baffle is provided on the inner wall of the sleeve tube, and the baffle is connected to the sliding tube through a return spring.

[0011] Preferably, the baffle is provided with an elastic rod extending into the sliding tube, and the elastic rod is provided with an extrusion disk, wherein the extrusion disk is provided with a through hole for the cutting metal wire to pass through, and the outer side wall of the extrusion disk abuts against the inclined surface of the sliding tube.

[0012] Preferably, the driving part includes a second rotating disc and a fixed shaft, and the second rotating disc is fixed on the fixed shaft, a sliding hole is opened on the second rotating disc, and a sliding block slides in the sliding hole, the sliding block is provided with a pushing part for pushing the rotating ring to reciprocate, and the second rotating disc is provided with an oil propulsion part for pushing the sliding block to slide on the sliding hole.

[0013] Preferably, the pushing part includes a lifting plate and a gear fixed coaxially with the rotating ring, the lifting plate slides vertically through a slide groove slider assembly, the sliding block is provided with an end rod and the lifting plate is driven to rise and fall through the slide groove and the end rod, and the end of the lifting plate is provided with a toothed plate meshing with the gear.

[0014] Preferably, the oil propulsion part includes an annular frame, and the second rotating disc rotates coaxially on the annular frame, and a first connecting tube is fixed on the annular frame, a second connecting tube is provided on the sleeve tube, and the first connecting tube and the second connecting tube are connected by a hose, and a telescopic rod connected to the sliding tube is provided on the second connecting tube, and a rubber plug is provided at the end of the telescopic rod.

[0015] Preferably, the oil propulsion part also includes a sliding groove connected to the sliding hole, and a triangular slider slides in the sliding groove, a pushing plate fixed to the sliding block is provided in the sliding groove, and the other end of the pushing plate is slidably connected to the inclined surface of the triangular slider.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the reciprocating motion process of the cutting metal wire cutting the plate to be cut, if the portion of the plate to be cut is a difficult-to-cut area, coupled with the downward pressure frame that steadily and uniformly descends on the bracket, the cutting metal wire that originally cuts the plate to be cut will be deformed in the vertical direction, that is, the cutting metal wire that was originally in a horizontal and straight state will become a curved cutting metal wire when it touches a hard area.

[0019] 2. In the present invention, the sliding block carries the end rod to slide in the sliding hole. The farther away from the fixed axis, the greater the amplitude of the lifting and lowering of the lifting plate by the end rod. Therefore, the greater the amplitude of the rotation of the toothed plate meshing gear, and finally the greater the amplitude of the reciprocating rotation of the rotating ring. Therefore, the phenomenon that will be produced is: the greater the amplitude of the reciprocating rotation of the rotating ring, the greater the amplitude of the reciprocating motion of the cutting metal wire pulling the outer wall, so the degree of cutting the plate to be cut is intensified, and the cutting of the plate to be cut is better completed.

[0020] 3. As the end rod slides in the sliding hole, the farther it is from the fixed axis, the faster the cutting wire will pull back and forth to cut the plate to be cut in the same amount of time. This will further intensify the cutting of the plate to be cut. Therefore, by changing the position of the sliding block in the sliding hole, the degree and speed of the cutting wire pulling back and forth to cut the plate to be cut can be controlled, which will better cut off the hard area where the plate to be cut is located and restore the cutting wire that was originally in a bent state to a horizontal and straight state.

DETAILED DESCRIPTION

[0028] Reference Figure 1-Figure 6 A multi-wire wire cutting machine includes a plate 3 to be cut, a bracket 1 and a lower pressing frame 2 that slides symmetrically on the bracket 1, wherein the two lower pressing frames 2 are driven to be pressed down by an external pressing device, and a cutting metal wire 9 for cutting the plate 3 to be cut is arranged between two adjacent positioning rods 4, so that it can be ensured that the cutting metal wire 9 will be pressed together with the lower pressing frame 2 during the pressing process. Due to the existence of the cutting metal wire 9, a cutting mark will be formed on the surface of the plate 3 to be cut below, and finally the cutting effect is completed.

[0029] Reference Figure 1 As shown, two positioning rods 4 are horizontally arranged between two adjacent lower pressure frames 2, and a rotating ring 8 is rotatably mounted on the positioning rod 4, wherein both ends of a cutting wire 9 are fixedly wound around the outer wall of the rotating ring 8, wherein the two rotating rings 8 rotate in the same direction. It should be noted that the reciprocating rotation of the two rotating rings 8 corresponding to the two positioning rods 4 will make the cutting wire 9 close to the upper surface of the plate 3 to be cut, and then the cutting wire 9 reciprocates to cut the plate 3 to be cut. This technical solution adopts the reciprocating motion of the cutting wire 9 instead of the traditional unidirectional sliding cutting of the cutting wire 9, which can quickly form the cutting surface.

[0030] Reference Figure 2 As shown, the rotating ring 8 rotates coaxially with the guide ring 6 through the bracket ring, so that when the rotating ring 8 reciprocates and cuts the plate 3 to be cut with the cutting metal wire 9 originally wound on its outer wall, the rotating ring 8 is always in a stable rotation state, and at the same time provides support for the reciprocating motion of the cutting metal wire 9.

[0031] A guide ring 6 is coaxially sleeved on the rotating ring 8, and the guide ring 6 slides linearly on the positioning rod 4 through the guide rod 5 and the socket 11. The guide ring 6 is also provided with a threaded rod for positioning with the positioning rod 4. It should be noted that since there are multiple cutting metal wires 9 sliding on the positioning rod 4, multiple cutting metal wires 9 can perform multi-wire cutting on the plate 3 to be cut, thereby achieving multi-segment cutting of the plate 3 to be cut.

[0032] The guide ring 6 is moved on the positioning rod 4, and then the threaded rod is rotated to allow the guide ring 6 with the threaded rod to rest against the positioning rod 4 to complete the positioning. The change in the position of the rotating rings 8 at both ends of the same cutting metal wire 9 will change the final inclination angle of the inclined surface of the cross-section of the plate 3 to be cut, thereby finally achieving the control of the cutting shape of the plate 3 to be cut.

[0033] Reference Figure 2 As shown, a wire sleeve 7 for guiding the cutting wire 9 is provided on the guide ring 6, and the wire sleeve 7 is horizontally rotated on the guide ring 6 by the first rotating disk 10, so that the horizontal swing of the wire sleeve 7 can be realized. Therefore, the movement of the cutting wire 9 will not be affected during the horizontal swing of the cutting wire 9, ensuring that the cutting wire 9 is always in a coaxial state with the wire sleeve 7.

[0034] The first rotating disc 10 rotates on the side wall of the guide ring 6 through the circular hole, and a through hole connected to the wire sleeve 7 is opened on the first rotating disc 10, wherein the cutting metal wire 9 passes through the wire sleeve 7 and the first rotating disc 10 is wound around the outer wall of the rotating ring 8. Therefore, during the reciprocating rotation of the rotating ring 8, the cutting metal wire 9 will be continuously pulled to move in the wire sleeve 7, and the movement of the cutting metal wire 9 will not be affected.

[0035] Reference Figure 3 In this state, a sliding tube 12 slides inside the wire sleeve 7, and an inner wall of the sliding tube 12 is provided with an inclined surface. A baffle 13 is provided on the inner wall of the wire sleeve 7, and the baffle 13 is connected to the sliding tube 12 through a return spring 17. Therefore, after the sliding tube 12 is squeezed, it will move toward the baffle 13 together with the telescopic rod 14 and squeeze the return spring 17. After the sliding tube 12 is no longer squeezed, the sliding tube 12 will be reset under the action of the return spring 17.

[0036] The extrusion plate 15 is provided with a through hole for the cutting wire 9 to pass through, and the outer wall of the extrusion plate 15 abuts against the inclined surface of the sliding tube 12. Therefore, the following phenomenon will occur during the process of the cutting wire 9 cutting the plate 3 to be cut:

[0037] First, during the reciprocating motion of the cutting wire 9 cutting the plate 3 to be cut, if the cutting portion of the plate 3 to be cut is an area that is difficult to cut, and the lower pressure frame 2 is steadily and uniformly descending on the bracket 1, the cutting wire 9 that originally cuts the plate 3 to be cut will be deformed in the vertical direction, that is, the cutting wire 9 that was originally in a horizontal and straight state will become a bent cutting wire 9 when it touches a hard area.

[0038] It should be noted that the bent and deformed cutting wire 9 will lead the extrusion disk 15 to deflect toward the sliding tube 12 , so when the extrusion disk 15 extrudes the sliding tube 12 , it will lead the sliding tube 12 to move toward the baffle 13 .

[0039] The baffle 13 is provided with an elastic rod 16 extending into the sliding tube 12, and the elastic rod 16 is provided with an extrusion disk 15. Therefore, when the cutting wire 9 moves with the extrusion disk 15, the existence of the elastic rod 16 can ensure that the extrusion disk 15 is in a deflected state, and at the same time, the elastic rod 16 ensures that the extrusion disk 15 has a restored posture. It should be noted that if the hardness of the cutting area of ​​the plate 3 to be cut is greater, the resistance encountered by the cutting wire 9 during the cutting process is greater, and the deformation tendency is greater. Then, the cutting wire 9 carries the extrusion disk 15 to squeeze the inclined surface on the sliding tube 12, and the sliding tube 12 moves toward the baffle 13. The distance of movement is longer.

[0040] Reference Figure 6 State, the second rotating disk 18 is provided with an oil propulsion part for pushing the sliding block 23 to slide on the sliding hole 22, the oil propulsion part includes an annular frame 19, and the second rotating disk 18 rotates coaxially on the annular frame 19, and a first connecting pipe 20 is fixed on the annular frame 19, a second connecting pipe is provided on the sleeve pipe 7, and the first connecting pipe 20 and the second connecting pipe are connected by a hose, a telescopic rod 14 connected to the sliding tube 12 is provided on the second connecting pipe, and a rubber plug is provided at the end of the telescopic rod 14. As the degree of extrusion of the sliding tube 12 increases, the sliding tube 12 carries the rubber plug at the end of the telescopic rod 14 to squeeze the oil in the second connecting tube into the first connecting tube 20 through the hose, an annular groove 29 is provided on the outer side wall of the second rotating disk 18, and the first connecting tube 20 is connected to the annular groove 29, and the annular groove 29 is connected to the sliding groove 31 through the connecting hole 30, and then this part of the oil will enter the sliding groove 31.

[0041] The oil propulsion part also includes a sliding groove 31 connected to the sliding hole 22, and a triangular slider 32 slides in the sliding groove 31, a pushing plate 33 fixed to the sliding block 23 is provided in the sliding groove 31, and the other end of the pushing plate 33 is slidably connected to the inclined surface of the triangular slider 32. As the oil enters the sliding groove 31, it will push the triangular slider 32, so that the pushing plate 33 takes the sliding block 23 away from the fixed axis 21.

[0042] The guide ring 6 is also provided with a driving part for driving the rotating ring 8 to reciprocate. Figure 4 and Figure 5 State, the driving part includes a second rotating disk 18 and a fixed shaft 21, and the second rotating disk 18 is fixed on the fixed shaft 21. It should be noted that a driving motor is also provided on the guide ring 6, and the output end of the driving motor is fixed to the fixed shaft 21, so that the second rotating disk 18 is always in a rotating state.

[0043] A sliding hole 22 is provided on the second rotating disk 18, and a sliding block 23 slides in the sliding hole 22, so the position of the sliding block 23 in the sliding hole 22 needs to be changed later. The sliding block 23 is provided with a pushing part for pushing the rotating ring 8 to reciprocate, and the pushing part is used to convert the continuous rotation force into a reciprocating rotation trend.

[0044] The pushing part includes a lifting plate 25 and a gear 28 fixed coaxially with the rotating ring 8. The lifting plate 25 slides vertically through the slide slot slider assembly, so the lifting plate 25 is always in a vertical state during the lifting process.

[0045] An end rod 24 is provided on the sliding block 23, and the lifting plate 25 is driven to rise and fall by the sliding groove 26 and the end rod 24. A tooth plate 27 meshing with the gear 28 is provided at the end of the lifting plate 25. It should be noted that the sliding block 23 on the second rotating disk 18 is lifted and lowered together with the end rod 24 inserted into the sliding groove 26. The lifting amplitude will cause the tooth plate 27 to mesh with the gear 28 to rotate a certain amplitude, and finally realize the reciprocating swing of the rotating ring 8.

[0046] It should be noted that the sliding block 23 carries the end rod 24 to slide in the sliding hole 22. The farther away from the fixed shaft 21, the greater the lifting and lowering range of the end rod 24 carrying the lifting plate 25, and therefore the greater the rotation range of the toothed plate 27 engaging the gear 28, and ultimately the greater the reciprocating rotation range of the rotating ring 8.

[0047] Therefore, the phenomenon that will be produced by this phenomenon is that the larger the amplitude of the reciprocating rotation of the rotating ring 8, the larger the amplitude of the reciprocating motion of the cutting metal wire 9 pulling the outer wall, so the degree of cutting the plate 3 to be cut is intensified, and the cutting of the plate 3 to be cut is completed better;

[0048] At the same time, as the end rod 24 slides in the sliding hole 22, the farther away from the fixed shaft 21, the faster the cutting wire 9 reciprocates to cut the plate 3 to be cut in the same time, which will further intensify the cutting of the plate 3 to be cut.

[0049] Therefore, by changing the position of the sliding block 23 in the sliding hole 22, the degree and speed of the cutting metal wire 9 to pull back and forth to cut the plate 3 to be cut can be controlled, which will better cut off the hard area of ​​the plate 3 to be cut and restore the cutting metal wire 9 that was originally in a bent state to a horizontal and straight state.

[0050] The working principle of the present invention is as follows:

[0051] A cutting metal wire 9 for cutting the plate 3 to be cut is arranged between two adjacent positioning rods 4, so that the cutting metal wire 9 can be pressed together with the lower pressing frame 2 during the pressing process. Due to the existence of the cutting metal wire 9, a cutting mark will be formed on the surface of the plate 3 to be cut below, and the cutting effect will be finally completed.

[0052] During the reciprocating motion of the cutting metal wire 9 cutting the plate 3 to be cut, if the cutting portion of the plate 3 to be cut is an area that is difficult to cut, and the lower pressure frame 2 is steadily and uniformly descending on the bracket 1, the cutting metal wire 9 originally cutting the plate 3 to be cut will be deformed in the vertical direction, that is, the cutting metal wire 9 originally in a horizontal and straight state will become a bent cutting metal wire 9 when it touches the hard area.

[0053] During the movement of the cutting metal wire 9 with the extrusion disk 15, the presence of the elastic rod 16 can ensure that the extrusion disk 15 is in a deflected state, and at the same time, the elastic rod 16 ensures that the extrusion disk 15 has a restored posture. It should be noted that if the hardness of the cutting area of ​​the plate 3 to be cut is greater, the resistance encountered by the cutting metal wire 9 during the cutting process is greater, and the deformation tendency is greater, then the cutting metal wire 9 carries the extrusion disk 15 to squeeze the inclined surface on the sliding tube 12, and the sliding tube 12 moves toward the baffle 13. The distance moved.

[0054] The sliding block 23 carries the end rod 24 to slide in the sliding hole 22. The farther away from the fixed shaft 21, the greater the lifting and lowering range of the end rod 24 carrying the lifting plate 25 is, so the greater the rotation range of the toothed plate 27 engaging the gear 28 is, and finally the reciprocating rotation range of the rotating ring 8 is greater.

[0055] The greater the amplitude of the reciprocating rotation of the rotating ring 8, the greater the amplitude of the reciprocating motion of the cutting wire 9 pulling the outer wall, so the degree of cutting the plate 3 to be cut is intensified, and the plate 3 to be cut is cut better;

[0056] At the same time, as the end rod 24 slides in the sliding hole 22, the farther away from the fixed shaft 21, the faster the cutting wire 9 reciprocates to cut the plate 3 to be cut in the same time, which will further intensify the cutting of the plate 3 to be cut.

[0057] Therefore, by changing the position of the sliding block 23 in the sliding hole 22, the degree and speed of the cutting metal wire 9 to pull back and forth to cut the plate 3 to be cut can be controlled, which will better cut off the hard area of ​​the plate 3 to be cut and restore the cutting metal wire 9 that was originally in a bent state to a horizontal and straight state.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
