Description

Technical Field

[0001] The utility model relates to a multi-station stone wire cutting machine, belonging to the technical field of stone cutting. Background Art

[0002] Stone (stone) cutting technology is a key technology widely used in the field of stone processing. It is used to cut, carve and process raw stones or stones to meet the needs of different buildings, sculptures, decorations and other uses. Stone cutting can be roughly divided into traditional manual cutting and mechanical cutting according to different applicable scenarios. Among them, traditional manual cutting is common in the fine carving scenes of handicrafts. It is usually carried out by skilled craftsmen using hand tools such as hammers, chisels, cutting knives, etc., to finely carve stones and process them into exquisite handmade stone products or works of art. Mechanical cutting uses mechanical equipment such as bridge cutters, chain saw cutters, water cutters, diamond wire cutters, etc. These machines can cut stones with higher efficiency and precision, and are widely used especially in large-scale production and engineering projects.

[0003] Among many mechanical cutting equipment, diamond wire cutting machine is a kind of equipment specialized for cutting metal or stone. Its working principle is to cut through high-speed rotating metal wire. This cutting method is usually called electric spark wire cutting, and diamond wire stone cutting machine is a common equipment for cutting stone. Specifically, the stone is fed into the cutting chamber of the diamond wire stone cutting machine, and a number of diamond wires are wound on four rotating rollers. When the motor drives the rollers to rotate the diamond wires, the diamond wires gradually approach the stone from one side until they enter the stone. Under the pulling and friction of the metal wires, the stone is cut into several equal parts.

[0004] When using a diamond wire stone cutting machine to cut stone, customers need to judge the material and quality of the stone in advance or need to cut off the scraps in advance, that is, they need to cut out a piece of stone first, make a preliminary judgment on the quality of the stone, cut the remaining stone again or directly cut off a layer of scraps on the surface of the stone, and then perform wire cutting on the entire stone. However, existing diamond wire stone cutting machines are often designed with only one station, and the diamond wires wound on the rollers of this station are arranged at equal intervals along the feeding direction of the stone. Therefore, when cutting the stone, it is impossible to meet the demand of cutting it into only one piece. Before using the diamond wire stone cutting machine to cut the stone, the stone needs to be cut manually, which reduces the overall production efficiency.

[0005] Therefore, a multi-station diamond wire stone cutting machine is urgently needed to meet the needs of different scenarios. When a multi-station diamond wire stone cutting machine is selected, the diamond wires of each station need to be linked during the diamond wire cutting process. When the diamond wire breaks during the cutting process, the broken diamond wire can be pulled out in time, reducing the difficulty of replacing the diamond wire. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a multi-station stone wire cutting machine, which meets the multi-station requirements and can cut a piece or a small number of pieces of the stone to be processed while wire cutting the stone that has completed the preliminary judgment or cut off the scraps, so as to meet the requirements of cutting a piece or a small number of pieces of the stone to be processed, thereby improving the overall production efficiency; at the same time, the diamond wires of the multiple stations can be linked to each other, and when the stone at the station on one side of several strands of diamond wire breaks the diamond wire, the broken diamond wire can be pulled out in time, reducing the difficulty of replacing the diamond wire.

[0007] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0008] A multi-station stone wire cutting machine, comprising:

[0009] frame;

[0010] The wire cutting mechanism is mounted in the frame and slidably connected to the frame. The stone includes stone A and stone B. Diamond wire A is wound around the wire cutting mechanism for wire cutting stone A.

[0011] The first station is arranged at the bottom of the frame and can slide relative to the frame. The stone A is placed on the first station. When the first station slides to a position corresponding to the diamond wire, the wire cutting mechanism falls to perform wire cutting on the stone A.

[0012] The second station is arranged at the bottom of the frame, adjacent to the first station and able to slide relative to the frame, and the stone B is mounted on the second station;

[0013] A diamond wire B is mounted on one side of the wire cutting mechanism and rotates synchronously with the diamond wire A. The diamond wire B corresponds to the second station and is used to cut the stone B. The diamond wire A is wound with multiple coils, and the diamond wire B is wound with several coils.

[0014] When the second work station slides, the stone B is placed under the diamond wire B. At this time, the wire cutting mechanism falls and the diamond wire B cuts the stone B.

[0015] Preferably, the frame comprises:

[0016] A plurality of longitudinal supports fixedly connected to the ground for supporting the wire cutting mechanism;

[0017] A plurality of transverse support members, any one of which is arranged between adjacent longitudinal support members, and a first driving member for driving the wire cutting mechanism to move up and down is arranged on the transverse support member;

[0018] A smooth surface fixing piece is provided on the longitudinal support piece, a slider corresponding to the smooth surface fixing piece is fixedly connected to the wire cutting mechanism, and the slider is placed on the smooth surface fixing piece and moves along the falling direction of the wire cutting mechanism;

[0019] The first driving member is drivingly connected to the slider and is used to provide driving force for the movement of the slider.

[0020] The rough side of the smooth fixing part is fixed on the longitudinal support part, and the smooth side provides a sliding track for the slider, which can reduce the damping between the slider and the smooth fixing part. The slider is fixedly connected to the wire cutting mechanism, and the first driving member can drive the slider, thereby driving the wire cutting mechanism to move up and down along the wire cutting direction.

[0021] Preferably, the first driving member comprises:

[0022] Servo motor A is fixed on any lateral support member;

[0023] The screw rod A is rotatably connected to the output end of the servo motor A.

The screw rod A is passed through the slider A to drive the slider A to move.

[0024] A servo motor B is disposed on the transverse support and is arranged opposite to the servo motor A;

[0025] The screw rod B is rotationally connected to the output end of the servo motor B and is arranged opposite to the screw rod A. The screw rod B passes through the slider B and is used to drive the slider B to move.

[0026] Servo motor A and servo motor B respectively control the movement of the wire cutting mechanism, and servo motor A and servo motor B can operate synchronously, that is, the movement of both sides of the wire cutting mechanism is realized, and there will be no tilting accident caused by the height difference on both sides of the wire cutting mechanism.

[0027] Preferably, a driving rod is mounted on the transverse support member, and the driving rod is rotatably connected to screw rod A and screw rod B respectively. The servo motor A serves as a main motor to drive screw rod A and screw rod B to rotate, and the servo motor B serves as a slave motor to supplement the speed difference between screw rod A and screw rod B.

[0028] When servo motor A uses the driving rod to synchronously lift the two sides of the wire cutting mechanism, due to the attenuation of mechanical transmission, there may be a height difference between the two sides of the wire cutting mechanism. When the height difference occurs, servo motor B starts and acts as an auxiliary slave motor to compensate for the speed difference between screw rod A and screw rod B, thereby effectively avoiding the accident of one side of the cutting mechanism tilting.

[0029] Preferably, the wire cutting mechanism comprises:

[0030] The frame is hollow and used to reserve a space for the stone A;

[0034] The diamond wire B is wound around the extended end of the roller body and is arranged opposite to the second driving member.

[0035] The main function of diamond wire A is to cut stone A, while diamond wire B can be synchronized with diamond wire A to achieve the purpose of cutting stone B. The hollow frame is mainly used to reserve space for accommodating stone A.

[0036] Preferably, the second driving member comprises:

[0037] The motor C is fixed to one side of the frame, and its output shaft drives a pair of adjacent rollers to rotate in the same direction;

[0038] Motor D is arranged opposite to motor C, and its output shaft drives another pair of rollers arranged adjacent to each other to rotate in the same direction;

[0039] The motor C and the motor D generate driving forces in the same direction.

[0040] Preferably, a rotating member is rotatably connected between the frame and the motor C and the motor D, and transmission members in opposite directions are mounted on the rotating member, and the transmission members are rotatably connected to the corresponding roller bodies.

[0041] Motor C and motor D can drive a pair of rollers respectively, and the number of motors used can be reduced while meeting the driving force requirements, thereby reducing production costs.

[0042] Preferably, the rotating member comprises a first rotating wheel and a second rotating wheel which are coaxially fixedly connected, and the transmission member comprises a first belt and a second belt, wherein the first belt is arranged between the first rotating wheel and the corresponding roller body, and is used to drive the roller body to rotate;

[0043] The second belt is arranged between the second rotating wheel and the corresponding roller body, and is used to drive the roller body to rotate. The first belt and the second belt are arranged in opposite directions.

[0044] The belt drive can effectively transmit the output rotational force of the motor C and the motor D to each roller body, so that the roller body can rotate in the same direction, thereby driving the diamond wire A to rotate and cut the stone A.

[0045] Preferably, a multi-stage adjustment component is fixedly mounted on the extending end of the roller body toward the diamond wire B, and the diamond wire B is placed on the multi-stage adjustment component for adjusting the distance from the diamond wire B to the frame.

[0046] The multi-stage adjustment component can meet the user's requirements for different cutting thicknesses of stone B when the diamond wire B is cutting the stone B. That is, when the user needs to cut a thicker stone B at one time, the different distances of the multi-stage adjustment component relative to the frame can be used to appropriately adjust the different distances from the diamond wire B to the frame, so that different thicknesses can be selected when cutting the stone B.

[0047] Preferably, a tension adjustment structure is fixedly connected to the side of the frame facing the diamond wire B, and the diamond wire B is mounted on the tension adjustment structure to adjust the tension of the diamond wire B.

[0048] When the diamond wire B is used for too long, the tension of the diamond wire B can be adjusted through the tension adjustment structure, so that the diamond wire B can always meet the tension requirement when cutting stone.

[0049] Preferably, the tension adjustment structure comprises:

[0050] The shell is hollow and fixedly connected to the frame;

[0051] The adjusting screw penetrates along the hollow position of the shell and is limited on the shell so as to be able to rotate idly relative to the outer side of the shell;

[0052] A sliding assembly, slidably connected to the adjusting screw;

[0053] The tension roller is fixedly connected to the sliding assembly and is disposed at the outer end of the housing, and can move up and down along the axial direction of the adjusting screw of the housing;

[0054] The tension roller is pressed against the diamond wire B. When the tension roller moves downward along the axial direction of the adjusting screw, the tension roller can press the diamond wire B and tighten the diamond wire B.

[0059] A sliding groove is provided on the side of the housing facing the diamond wire B, and the tension roller is fixedly connected to the sliding member and moves up and down along the direction in which the sliding groove extends.

[0060] The sliding groove provides an escape space for the tension roller to move up and down, effectively preventing the shell from interfering with the movement of the tension roller.

[0061] Preferably, the first workstation is provided with a first track along the feeding direction of stone A, on which a trolley A is provided, which slides along the direction of the first track, and on both sides of the trolley A are limiters A, on which stone A is fixed, and the wire cutting mechanism cuts stone A in a direction perpendicular to the limiters A.

[0063] The beneficial effects of the utility model are:

[0064] (1) Through the utility model, a workstation is added on the basis of the existing stone wire cutting machine, which can meet the needs of cutting multiple pieces of stone A and cutting several pieces of stone B at the same time, so that two pieces of stone can be processed separately at the same time, that is, while cutting the stone to be processed (stone B that needs to be cut into one piece or a small number of pieces), the processed stone (stone A) can be cut into multiple pieces, meeting the needs of different workstations, thereby improving the overall production efficiency.

[0065] (2) Through the utility model, the linkage structure is utilized to synchronously drive the diamond wire A and the diamond wire B installed on the frame, thereby reducing the number of driving parts and reducing the use cost in actual production.

[0066] (3) Through the present invention, the adjacent arrangement of the first workstation and the second workstation can avoid mutual interference between the first workstation and the second workstation, thereby improving the coordination performance of the entire machine and improving production efficiency.

[0067] (4) Through the utility model, a servo motor is used to drive a wire cutting mechanism to cut stone, thereby improving the stability of the machine body. At the same time, one or two servo motors can be selected to effectively drive the wire cutting mechanism. When one servo motor is selected, a driving rod can be used to link the driving modules on both sides of the wire cutting mechanism (refer to the four-wheel drive transmission structure), thereby driving the wire cutting mechanism as a whole to move up and down along the cutting direction. When two servo motors are selected, one of them can be used as an active drive motor and the other as a slave drive supplementary motor. When a height difference occurs on both sides of the wire cutting mechanism, the supplementary motor takes effect to compensate for the lack of power. When two servo motors are selected, the driving rod can also be removed to allow the servo motors on both sides to run synchronously, thereby achieving the purpose of synchronous lifting and lowering of both sides of the wire cutting mechanism. The utility model has high adaptability and can select different strategies according to different scenarios.

[0068] (5) Through the utility model, two motors are used to drive two rollers respectively, thereby replacing the technical solution of using four motors to drive one roller each in the prior art. Under the premise of meeting the driving force, the number of motors can be reduced, which is conducive to reducing the cost of use.

[0069] (6) Through the utility model, the diamond wire A and the diamond wire B are linked, that is, the diamond wire A and the diamond wire B are designed to be one diamond wire, and the diamond wire A in the frame is wound with multiple coils along the roller body, and then the diamond wire A is directly guided to the outer end of the frame through the holes on the frame to form a plurality of diamond wires B, so that the diamond wire A and the diamond wire B can rotate synchronously and at the same frequency to reciprocate and cut the stone A and the stone B respectively, and then the diamond wire B is guided again through the holes on the frame to the wire taking-up device on the outside of the frame away from the end of the diamond wire B, so that when the stone at the work station on one side of the plurality of diamond wires breaks the diamond wire, the broken diamond wire can be pulled out in time, reducing the difficulty of replacing the diamond wire.

DETAILED DESCRIPTION

[0084] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0085] Example

[0086] like Figure 1-Figure 13 As shown, a multi-station stone wire cutting machine includes: a frame, a wire cutting mechanism, a first station 45 and a second station 46. The frame is composed of four longitudinal support members 1 and four transverse support members 2 to form a six-sided hollow support structure. The longitudinal support members 1 constitute support columns, stand on the ground, and are fixed to the ground by bolts. Each transverse support member 2 is arranged between two adjacent longitudinal support members 1, and can be firmly fixed to the longitudinal support members 1 by bolts or welding. Two smooth fixing members 17 are fixed on each longitudinal support member 1 along the cutting direction of the wire cutting mechanism. The smooth fixing member 17 in this embodiment is an L-shaped bending member, which is directly fixed to the corners of the longitudinal support member 1 by welding or rivets. One side of the smooth fixing member 17 is a rough surface structure, and the side opposite to the rough surface structure is a smooth surface structure. A slider is slidably connected to the smooth surface structure of the two smooth surface fixing members 17 of any longitudinal support member 1, and a slider is slidably connected to each of the adjacent longitudinal support members 1. A transverse column 47 is fixedly connected between the adjacent sliders by bolts or pins, and one of the transverse columns 47 is fixed to the online cutting mechanism by bolts or welding, that is, a transverse column 47 is arranged in parallel on both sides of the online cutting mechanism to support the online cutting mechanism. For this reason, the online cutting mechanism can move up and down along the extension direction of the smooth surface structure in the frame composed of the transverse support member 2 and the longitudinal support member 1. Among them, the rough side of the smooth surface fixing member 17 is fixed to the longitudinal support member 1, and the smooth side (smooth surface structure) provides a sliding track for the slider, which can reduce the damping between the slider and the smooth surface fixing member 17. In this embodiment, the stone includes stone A13 and stone B14, stone A13 is limited to the first station 45, and stone B14 is limited to the second station 46.

[0087] In this utility model, reference Figure 1 , Figure 3The wire cutting mechanism includes: a frame 3, four rollers, a second driving member, a diamond wire A15 and a diamond wire B16. The frame 3 is designed as a hollow structure, which is used to reserve space for the stone A13. A roller passes through each of the four corners of the frame 3, which are roller 4, roller 5, roller 6 and roller 7 in counterclockwise order. Both ends of the roller extend out of the outer end of the frame 3. The second driving member is mounted on one side of the frame 3 and is rotatably connected to an extended end of the roller to drive the roller to rotate. The diamond wire A15 is wound around the roller and is located in the hollow position of the frame 3; the diamond wire B16 is wound around the extended end of the roller and is arranged opposite to the second driving member. The main function of the diamond wire A15 is to cut the stone A13, and the diamond wire B16 can be synchronized with the diamond wire A15 to achieve the purpose of cutting the stone B14. The hollow frame 3 is mainly used to reserve space for accommodating the stone A13.

[0088] Specifically, refer to Fig. 9 In this embodiment, the diamond wire A15 and the diamond wire B16 are one diamond wire, and the diamond wire A15 is drawn out from a wire-releasing device arranged on the same side of the frame as the second driving member (the wire-releasing device is a common wire-releasing device on the cutting mechanism in the prior art, and a plurality of direction-changing guide rollers are arranged between the wire-releasing device and the roller body, and the diamond wire A15 can be guided to the roller body by the direction-changing guide rollers, and wound several turns on the four roller bodies in a gap, and a wire outlet hole 49 is arranged on the side of the frame 3 facing the diamond wire B, which is used to guide the diamond wire A15 along the wire outlet hole 4950 directly to the outer end of the frame 3 to form the diamond wire B16, and after the diamond wire B16 is wound around the roller extension end at the outer end of the frame 3 for one turn, it directly enters the side fixed end of the frame 3 through the wire entry hole 50 arranged on the frame 3, and a plurality of direction-changing guide rollers are installed on the side fixed end to guide the diamond wire, and finally the diamond wire A15 is guided to the frame 3 away from the diamond wire B16. A wire-receiving device is arranged on one side. The wire-receiving device in the utility model is a common wire-receiving structure. In the utility model, the wire-receiving device and the wire-releasing device are installed diagonally. Through the utility model, the diamond wire A15 and the diamond wire B16 are linked, that is, the diamond wire A15 and the diamond wire B16 are designed to be one diamond wire, and the diamond wire A15 in the frame is wound with multiple coils along the roller body, and then the diamond wire A15 is directly guided to the outer end of the frame 3 through the wire outlet hole 49 on the frame 3 to form a plurality of strands of diamond wire B16, so that the diamond wire A15 and the diamond wire B16 are synchronously rotated with the same frequency to reciprocate back and forth to cut the stone A13 and the stone B14 respectively, and then the diamond wire B16 is guided again through the wire entry hole 50 on the frame 3 to the wire-receiving device on the outside of the frame away from one end of the diamond wire B, so that when the stone at the workstation on one side of the plurality of strands of diamond wire breaks the diamond wire, the broken diamond wire can be pulled out in time, reducing the difficulty of replacing the diamond wire.

[0089] Since the direction of the diamond wire needs to be changed after it comes out of the wire-releasing device, the wire-retracting mechanism or the wire-retracting mechanism and enters the first workstation 45 so that it can be wound around the No. 1 roller 4, the No. 2 roller 5, the No. 3 roller 6 and the No. 4 roller 7 in the first workstation 45, the direction of the diamond wire also needs to be changed when the diamond wire comes out of the first workstation 45 and enters the second workstation 46 so that it can be wound around the rollers in the second workstation 46. Changing the direction of the diamond wire is a conventional design in the field, and is not the utility model point of the present application, and will not be elaborated in this application.

[0090] Among them, reference Figure 1 , Figure 2 , Figure 3 The second driving member includes: motor C8 and motor D9. Specifically, a rotating member 10 is rotatably connected between the No. 1 roller body 4 and the No. 2 roller body 5, the No. 3 roller body 6 and the No. 4 roller body 7 on the frame 3, and the motor C8 and the motor D9 are respectively connected to a rotating member 10, that is, the output shaft of the motor C8 is connected to a rotating member 10, and the output shaft of the motor D9 is connected to another rotating member 10. Transmission members in opposite directions are installed on the rotating member 10, and the transmission members are connected to the corresponding roller bodies in rotation. For example, the No. 1 roller body 4 is connected to the rotating member 10 through the No. 1 transmission member, and the No. 2 roller body 5 is connected to the rotating member 10 through the No. 2 transmission member, and the No. 1 transmission member is set in the opposite direction to the No. 2 transmission member. The connection between the No. 3 roller body 6 and the No. 4 roller body 7 and the transmission member is similar, so that the driving force of the motor C8 and the motor D9 can be synchronously transmitted to the No. 1 roller body 4, the No. 2 roller body 5, the No. 3 roller body 6, and the No. 4 roller body 7. Among them, the motor C8 and the motor D9 generate driving forces in the same direction. Motor C8 and motor D9 can drive a pair of rollers respectively, which can reduce the number of motors used while meeting the driving force requirements, thereby reducing production costs.

[0091] The rotating member 10 includes a first rotating wheel 101 and a second rotating wheel 102 which are coaxially fixedly connected. The transmission member includes a first belt 11 and a second belt 12. The first belt 11 is arranged between the first rotating wheel 101 and the corresponding roller body (No. 1 roller body 4) to drive the roller body to rotate; the second belt 12 is arranged between the second rotating wheel 102 and the corresponding roller body (No. 2 roller body 5) to drive the roller body to rotate. The first belt 11 and the second belt 12 are arranged in opposite directions. The utility model can effectively transmit the output rotational force of the motor C8 and the motor D9 to each roller body by belt transmission, so that the roller body can rotate in the same direction, thereby driving the diamond wire A15 to rotate and cut the stone A13.

[0092] In the utility model, in order to be able to cut two pieces of stone synchronously and to meet the purpose of cutting only one piece or a small number of pieces (i.e., several pieces) of one of the stones, a workstation is added on the basis of the existing stone wire cutting machine, that is, a first workstation 45 and a second workstation 46 are respectively arranged on both sides of the frame, the first workstation 45 cuts the stone A13, and the second workstation 46 synchronously cuts the stone B14, and the second workstation 46 is set to cut several pieces.

[0093] It should be noted that the stone slices cut out by the first station 45 are generally multiple pieces, which are generally more than 10 pieces, dozens of pieces, hundreds of pieces, etc.; the stone slices cut out by the second station 46 are generally 1 piece, a small number of pieces, etc., which are generally 10 pieces or less; in common cases, the number of stone slices cut out by the second station 46 is much smaller than the number of stone slices cut out by the first station 45.

[0094] The first station 45 is laid at the bottom of the frame and can slide relative to the frame. The stone A13 is placed on the first station 45. When the first station 45 slides to the position corresponding to the diamond wire A15, the wire cutting mechanism falls and the stone A13 is wire cut. The second station 46 is laid at the bottom of the frame, adjacent to the first station 45, and can slide relative to the frame. The stone B14 is mounted on the second station 46. The diamond wire A15 is wound with multiple coils, and the diamond wire B16 is wound with several coils. When the second station 46 slides, the stone B14 is placed under the diamond wire B16. At this time, the wire cutting mechanism falls, and the diamond wire B16 cuts the stone B14.

[0095] Specifically, refer to Figure 1 and Figure 8The first station 45 is provided with a first track 37 along the feeding direction of the stone A13, a trolley A38 is provided on the first track 37, the trolley A38 slides along the direction of the first track 37, and limiters A39 are provided on both sides of the trolley A38. The stone A13 is fixed on the limiters A39, and the wire cutting mechanism cuts the stone A13 in a direction perpendicular to the limiters A39. When the trolley A38 moves to the bottom of the hollow structure of the frame 3, the wire cutting mechanism is controlled to move downward along the smooth surface structure as a whole to cut the stone A13, and finally cut into several pieces. The second station 46 is provided with a second track 40 along the feeding direction of the stone B14, a trolley B41 is provided on the second track 40, the trolley B41 slides along the direction of the second track 40, and limiters B42 are provided on both sides of the trolley B41. The stone B14 is fixed on the limiters B42, and the wire cutting mechanism cuts the stone B14 in a direction parallel to the limiters B42. The bottom of the trolley A38 and the trolley B41 are both provided with wheels, and the wheels slide in the corresponding tracks. In order to avoid the interference between the first track 37 and the second track 40, a gap is provided at the intersection of the first track 37 and the second track 40, and the gap is smaller than the wheel diameter of the trolley A38 and the trolley B41 to avoid the wheels of the trolley A38 or the trolley B41 from being stuck in the gap. When the trolley B41 runs to the lower end of the diamond wire B16 through the second track 40, the diamond wire B16 cuts the stone B14 once, and finally forms a number of cutting planes. In the utility model, the limiter A39 and the limiter B42 are both interception fences composed of a plurality of plates of different lengths. A plurality of bayonet grooves are provided at the edge positions on both sides of the trolley A38 and the trolley B41. The bottom of the interception fence is inserted into the bayonet groove for fixing the stone A and the stone B.

[0096] refer to Figure 8 In order to avoid collecting the fallen stone cutting debris, in some embodiments, a debris collection groove 44 is provided on the inner side of the first track 37 and the second track 40, and the two sides of the debris collection groove 44 are inclined toward the middle position to collect the debris dropped during cutting.

[0097] In some embodiments, reference Figure 5 The cross section of the slider is a concave groove that can accommodate the smooth surface structure, and a rubber sheet 25 is fixedly connected to the side in contact with the smooth surface structure to effectively avoid wear on the slider. At the same time, since the rubber material can increase the friction between it and the smooth surface structure, during the sliding process of the slider, the slider is effectively prevented from slipping and failing due to the smooth surface structure.

[0098] In order to utilize the driving force to enable the wire cutting mechanism to move up and down along the smooth surface structure, a first driving member is further provided in this embodiment. That is, a servo motor A22 is fixedly mounted on one of the transverse support members 2 through a motor seat, and the output end of the servo motor A22 drives a linkage rod A26 transversely, and by installing a fixed base 27 at each end of the top of the transverse support member 2, the linkage rod A26 can be mounted on the transverse support member 2 and arranged parallel to the transverse support member 2.

[0099] Specifically, refer to Figure 7 and Fig.12 The fixed base 27 is a four-sided hollow design. A bevel gear A29 is fixed at each end of the linkage rod A26. The bevel gear A29 is sleeved in the hollow of the fixed base 27 and can rotate relative to the fixed base 27. Two opposite screw rods A20 are set between two adjacent longitudinal support members 1. The head of the screw rod A20 is placed in the fixed base 27. A bevel gear B30 is fixedly installed at the head of the screw rod A20. The bevel gear B30 can rotate relative to the hollow of the fixed base 27. At this time, the bevel gear A29 and the bevel gear B30 can mesh with each other. The screw rods A20 on both sides of the servo motor A22 are each threadedly connected to a slider A18, so that the slider A18 can move up and down along the axis of the screw rod A20. In this process, when the servo motor A22 drives the linkage rod A26 to rotate, the linkage rod A26 drives the bevel gears A29 at both ends to rotate, and the rotation of the bevel gear A29 drives the bevel gear B30, which in turn drives the screw rod A20 to rotate. Assuming that the servo motor A22 controls the screw rod A20 to rotate clockwise along its axis, the slider A18 will drive the wire cutting mechanism to rise along the screw rod A20. Then, when the servo motor A22 controls the screw rod A20 to rotate counterclockwise along its axis, the slider A18 will drive the wire cutting mechanism to fall along the screw rod A20 for cutting stone.

[0100] refer to Fig.12In order to ensure that both ends of the wire cutting mechanism fall at the same time, a driving rod 24 is added to the adjacent horizontal support member 2 with the servo motor A22, and a fixed base 27 is provided at each corner of the top of the frame. A screw rod B21 is rotatably connected to each of the two longitudinal support members 1 opposite to the servo motor A22. The head of the screw rod B21 is the same as the screw rod A20, and a linkage rod B28 is rotatably connected between the two screw rods B21. The linkage rod B28 has the same structure as the linkage rod A26. The positional relationship and connection relationship between the screw rod B21 and the linkage rod B28 are the same as the positional relationship and connection relationship between the screw rod A20 and the linkage rod A26. A corresponding slider B19 is also provided on the screw rod B21. Since both ends of the driving rod 24 are provided with bevel gears A29 for linkage, both ends of the screw rod B21 are provided with bevel gears B30, and the bevel gears A29 and B30 are linked, the slider B19 can also drive one side of the wire cutting mechanism to move up and down along the screw rod B21. At this time, the entire first driving member is equivalent to a four-wheel drive linkage, and the servo motor A22 drives both sides of the wire cutting mechanism to move up and down synchronously along the screw rod A20 and the screw rod B21 respectively. When the wire cutting mechanism moves downward, it is used to cut stone.

[0101] In some embodiments, when the servo motor A22 uses the driving rod 24 to synchronously lift the two sides of the wire cutting mechanism, due to the attenuation of the mechanical transmission, a height difference may occur on both sides of the wire cutting mechanism. When a height difference occurs, the wire cutting mechanism may tilt and cause the cutting to deviate. In order to effectively avoid this deviation, a servo motor B23 is introduced, which can be rotatably connected to the linkage rod B28, that is, the servo motor B23 acts as a compensation motor to provide a rotational force for the linkage rod B28, and transmits the rotational force to the screw rod B21, ensuring that the screw rod A20 and the screw rod B21 can maintain a synchronous speed during the mechanical transmission process.

[0102] Specifically, a height sensor (which may be an ultrasonic sensor, a laser sensor, etc.) may be installed at both ends of the online cutting mechanism facing the ground. The height sensor collects signals and transmits the height difference numerical signal to a PID controller (feedback control system controller) through a circuit. The PID controller compares the change in the height difference with the predetermined target height difference (assuming that the predetermined target height difference is ±1.2 mm). When the actual height difference exceeds the predetermined target height difference, the PID controller transmits a start signal to the servo motor B23, and then the control signal of the servo motor B23 is transmitted to the drive circuit of the servo motor B23. At this time, the drive circuit issues a speed control instruction to the servo motor B23 (changes the current of the servo motor B23). During this process, the height sensor continuously provides feedback of the actual position so as to timely adjust the control output of the servo motor B23, so as to adjust the rotation speed of the screw rod B21 at any time, thereby ensuring that the screw rod A20 rotates synchronously with the screw rod B21, thereby effectively avoiding the accident of one side of the cutting mechanism tilting.

[0103] In some embodiments, reference Fig.13 , the driving rod 24 can be removed, and the servo motor A22 and the servo motor B23 are retained. The parameters of the servo motor A22 and the servo motor B23 are the same. The servo motor A22 and the servo motor B23 are started at the same time in the electric control, so that the two sides of the wire cutting mechanism can rise and fall at the same time. In this embodiment, the start buttons of the servo motor A22 and the servo motor B23 can be linked. The servo motor A22 and the servo motor B23 can be started by one button, and the servo motor A22 and the servo motor B23 can be stopped at the same time by another button.

[0104] In the above embodiment, the technical points related to the forward and reverse rotation of the servo motor involved are existing technologies, such as introducing a PID controller, inputting the error between the actual position and the target position, and outputting a control signal transmitted to the servo motor A22 or the servo motor B23. Where error = target position - actual position, so that

[0105] Kp, Ki, and Kd are the proportional, integral, and differential gains, respectively, and can be adjusted according to the dynamic characteristics of the system.

[0106] Set Output to positive, increase the output of servo motor A22 or servo motor B23, and servo motor A22 or servo motor B23 rotates forward;

[0107] Set Output to negative to reduce the output of servo motor A22 or servo motor B23, and servo motor A22 or servo motor B23 will reverse.

[0108] In the above embodiments, the control parts are all connected to an external power source to provide necessary power support for the entire control.

[0109] In some embodiments, reference Fig. 9 , a multi-stage adjustment component 31 is fixedly installed on the extension end of the roller body toward the diamond wire B16, that is, a multi-stage adjustment component 31 is fixedly installed on the extension end of the No. 1 roller body 4, the No. 2 roller body 5, the No. 3 roller body 6, and the No. 4 roller body 7. The diamond wire B16 is placed on the multi-stage adjustment component 31, which is used to adjust the distance from the diamond wire B16 to the frame 3. The multi-stage adjustment component 31 can meet the user's requirements for different thicknesses of the stone B14 when the diamond wire B16 cuts the stone B14. That is, when the user requires a thicker stone B14 to be cut at one time, the different distances of the multi-stage adjustment component 31 relative to the frame 3 can be used to appropriately adjust the different distances from the diamond wire B16 to the frame 3, so that different thicknesses can be selected when cutting the stone B14. Among them, reference Figure 4 At least three limit slots 311 are provided on the multi-stage adjustment component 31, and the diamond wire B16 is wound around one of the limit slots 311. The three limit slots 311 are equivalent to positions at at least three different distances from the frame. The user can cut the stone B14 to different thicknesses as needed, that is, when the thickest slice is required, the diamond wire B16 can be hung on the limit slot 311 farthest from the frame.

[0110] In some embodiments, reference Fig. 9 , Fig.10 , Fig.11 , a tension adjustment structure is fixedly connected to one side of the frame facing the diamond wire B16, and the diamond wire B16 is mounted on the tension adjustment structure to adjust the tension of the diamond wire B16. When the diamond wire B16 is used for too long, the tension of the diamond wire B16 can be adjusted through the tension adjustment structure, so that the diamond wire B16 can always meet the tension requirement when cutting stone. Among them, the tension adjustment structure includes: a hollow shell 32, an adjusting screw 33, and a tension roller 43. Among them, the shell 32 is fixedly connected to the frame, the adjusting screw 33 passes through the hollow position of the shell 32, and is limited on the shell 32, and can idle relative to the outside of the shell 32; the sliding assembly is slidably connected to the adjusting screw 33; the tension roller 43 is fixedly connected to the sliding assembly, and is arranged at the outer end of the shell 32, and can move up and down along the axial direction of the adjusting screw 33 of the shell 32. The tension roller 43 is pressed against the diamond wire B16. When the tension roller 43 moves downward along the axial direction of the adjusting screw 33, the tension roller 43 can press the diamond wire B16 and tighten the diamond wire B16.

[0111] Specifically, the sliding assembly includes: a hollow rod 34 and a sliding member 35. The hollow rod 34 is coaxially arranged with the adjusting screw 33, and one end of the adjusting screw 33 is placed in the hollow rod 34 and is threadedly slidably connected to each other; the sliding member 35 is placed in the hollow cavity of the housing 32 and is slidably connected to both ends of the cavity; the hollow rod 34 is fixedly connected to the sliding member 35; the housing 32 is provided with a sliding groove 321 on the side facing the diamond wire B16, and the tension roller 43 is fixedly connected to the sliding member 35 and moves up and down along the direction in which the sliding groove 321 extends. The sliding groove 321 provides an escape space for the tension roller 43 to move up and down, effectively preventing the housing 32 from interfering with the movement of the tension roller 43. A spring 36 is wound around the hollow rod 34, which has a certain elastic potential energy. When the diamond wire B16 contacts the tension roller 43, the diamond wire B16 has an elastic feedback to the tension roller 43, so as to avoid excessive instantaneous force acting on the diamond wire B16 when adjusting the tension roller 43, resulting in excessive pressing force of the diamond wire B16, which makes it easy for the diamond wire B16 to get stuck on the tension roller 43. The user can adjust the position of the hollow rod 34 relative to the hollow cavity in the housing 32 by inserting the hexagonal screw into the center position of the adjusting screw 33, and then tightening or loosening the adjusting screw 33, so as to adjust the distance from the tension roller 43 to the diamond wire B16.

[0112] In this embodiment, a cylinder 48 can be installed on the frame, and the distance between the tension roller 43 and the frame can be changed by the extension and contraction of the cylinder 48, so that it can cooperate with the multi-stage adjustment component 31 to make the diamond wire B16 on a side parallel to the side of the frame. In addition, a plurality of receiving grooves 431 can also be set on the roller of the tension roller 43, and the receiving grooves 431 can correspond to the limit grooves 311 on the multi-stage adjustment component 31, so as to better cooperate with the multi-stage adjustment component 31 to complete the adjustment of the diamond wire B16.

[0113] Since diamond wire is a cutting tool made of diamond grains embedded in diamond wire, using diamond wire to cut stone has the following advantages:

[0114] 1. High precision: Diamond wire cutting can achieve very high precision, so it is suitable for engineering projects that require precise size and shape. This is especially useful for stone carving, stone splicing and other work.

[0115] 2. Flexibility: Diamond wire cutting can cut along complex contours, so it is suitable for stones of various shapes and design requirements. It can be used to cut curves, bends or complex patterns, providing greater design freedom.

[0116] 3. Low vibration: Compared with some other cutting methods, diamond wire cutting produces relatively low vibration. This helps to reduce damage to the stone surface and improve cutting quality.

[0117] Suitable for hard materials: Diamond wire cutting is suitable for hard stones such as marble, granite, quartz, etc. It can complete efficient cutting without damaging the stone.

[0118] 4. Reduce waste: Due to the small diameter of the diamond wire, the loss during cutting is relatively small, so material waste can be reduced.

[0119] 5. Environmental protection: Diamond wire cutting does not involve chemical substances, reduces the impact on the environment, and meets some environmental protection standards.
