Description

Technical Field

[0001] This invention relates to the field of stone cutting equipment technology, specifically to high-efficiency stone wire saw cutting equipment. Background Technology

[0002] Diamond wire sawing is one of the main technologies for stone cutting. Wire sawing has many advantages such as high yield, low energy consumption, and high flatness after cutting. Diamond wire for cutting stone refers to wire with diamond particles electroplated on the surface of metal cutting wire. During cutting, the diamond wire is reciprocated by a winding mechanism, which can efficiently cut the stone by utilizing the diamond particles on the surface of the diamond wire. In existing wire sawing equipment, the cutting wire needs to be continuously wound from the head to the tail of the main guide wheel. That is, a single cutting wire is wound many times on each main guide wheel, forming multiple parallel and spaced cutting segments. However, during the cutting process, it is not possible to effectively ensure the consistency of tension between multiple cutting segments. Moreover, because the length of the cutting wire pulled out is very long, it increases the probability of wire breakage, and the repair after wire breakage is relatively troublesome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-efficiency stone wire saw cutting equipment that can effectively reduce the probability of wire breakage, facilitate wire threading and repair after breakage, and effectively ensure the consistency of tension among multiple cutting wires.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-efficiency stone wire saw cutting equipment, including an installation frame, a lifting frame, a lifting drive mechanism, a stone clamping and placing mechanism, and a wire saw cutting mechanism. The lifting frame is located inside the installation frame and is slidably connected to the installation frame through a first sliding component. The lifting drive mechanism is located on the installation frame and is used to drive the lifting frame to move up and down. The stone clamping and placing mechanism is located below the lifting frame and is used to clamp and place the stone body. The wire saw cutting mechanism is located on the lifting frame and includes a cutting wire, a first take-up and release assembly, a second take-up and release assembly, a synchronous tensioning assembly, and a tension adjusting assembly. The two ends of the cutting wire are respectively connected to the first take-up and release assembly and the second take-up and release assembly. The synchronous tensioning assembly and the tension adjusting assembly are respectively located on the left and right sides of the lifting frame. The cutting wire consists of multiple wires and is arranged in a U-shaped winding manner between the synchronous tensioning assembly and the tension adjusting assembly. The synchronous tensioning assembly is used to simultaneously tension the multiple cutting wires, and the tension adjusting assembly is used to adjust and balance the tension between the multiple cutting wires.

[0005] Furthermore, the first take-up and undo assembly includes a first take-up and undo motor, a first rotating shaft, a first take-up and undo reel, and a first mounting base. The first rotating shaft is rotatably mounted on the first mounting base via a first bearing. The first mounting base is fixedly mounted on the lifting frame. The first take-up and undo motor is fixedly mounted on the first mounting base. The motor shaft of the first take-up and undo motor is connected to one end of the first rotating shaft via a first coupling. The first take-up and undo reel is fixedly mounted on the first rotating shaft. The first take-up and undo reel has multiple first take-up and undo grooves, each corresponding to a different cutting wire. The second take-up and unwind assembly includes a second take-up and unwind motor, a second rotating shaft, a second take-up and unwind reel, and a second mounting base. The second rotating shaft is rotatably mounted on the second mounting base via a second bearing. The second mounting base is fixedly mounted on the lifting frame. The second take-up and unwind motor is fixedly mounted on the second mounting base. The motor shaft of the second take-up and unwind motor is connected to one end of the second rotating shaft via a second coupling. The second take-up and unwind reel is fixedly mounted on the second rotating shaft. The second take-up and unwind reel has multiple second take-up and unwind slots, and each of the multiple second take-up and unwind slots corresponds to a multiple cutting wire.

[0006] Furthermore, the tension adjustment assembly includes an adjustment rope, a fixed adjustment wheel, a movable adjustment wheel, a first guide wheel, and a movable adjustment frame. Both ends of the adjustment rope are fixedly mounted on corresponding fixed rods, which are fixedly mounted on the upper end of the lifting frame. Multiple fixed adjustment wheels are evenly spaced and rotatably mounted on a first fixed shaft, which is also fixedly mounted on the upper end of the lifting frame. A movable adjustment wheel is positioned between two adjacent fixed adjustment wheels. The adjustment rope alternately winds around multiple fixed and movable adjustment wheels in an S-shaped winding pattern. The movable adjustment wheel is rotatably mounted on one end of the movable adjustment frame, which is laterally slidably connected to the lifting frame via a second sliding assembly. Two first guide wheels, positioned vertically, are rotatably mounted on the other end of the movable adjustment frame. The central axis of the first guide wheel is perpendicular to the central axis of the movable adjustment wheel. A cutting line passes between the two first guide wheels. The movable adjustment frame has clearance notches for the cutting line to pass through. The number of movable adjustment wheels is twice the number of cutting lines.

[0007] Furthermore, the wire saw cutting mechanism also includes multiple elastic tensioning and resetting components, each corresponding to a multiple movable adjustment frame. Each elastic tensioning and resetting component includes a fixed base, a first compression spring, a reset plate, a second compression spring, a locking block, a fixing sleeve, a sealing plate, and a trigger. The fixed base is fixedly installed on the upper end of the lifting frame and located on one side of the movable adjustment frame. The fixed base has a first cavity open to one side of the movable adjustment frame. The first cavity contains, from the inside out, a first compression spring and a reset plate. The reset plate is square-shaped and fits the first cavity. One end of the first compression spring is fixedly connected to the fixed base, and the other end is fixedly connected to the reset plate. Both the left and right side walls of the fixed base have through holes. Fixing sleeves are fixedly installed on the outer surfaces of both sides of the fixed base at the through holes. Each fixing sleeve has a second cavity penetrating both ends and communicating with the through holes. The locking block and the... The hole is adapted to slide through the hole. One end of the locking block can be detachably engaged with the edge of one side surface of the reset plate. Positioning protrusions located in the second cavity are fixed on both sides of the other end of the locking block. A sealing plate is fixedly installed at the outer opening of the fixed sleeve. At least one second compression spring is also provided in the second cavity. One end of the second compression spring abuts against the locking block and the other end abuts against the sealing plate. The trigger is set on the moving adjustment frame. There are two triggers, which are set one-to-one with the two fixed sleeves. When the moving adjustment frame moves to the corresponding trigger position on the side of the fixed seat, it can drive the trigger to trigger the locking block to move and make one end of the locking block move away from the reset plate to release the locking limit on the reset plate. At this time, under the elastic force of the first compression spring, the reset plate can be pushed to the side of the moving adjustment frame and the moving adjustment frame can be pushed to move away from the side of the fixed seat to reset.

[0008] Furthermore, the trigger is a strip-shaped trigger plate, with a trigger slot inside the locking block and an clearance slot on the fixing sleeve. One end of the strip-shaped trigger plate is fixed to the moving adjustment frame, and the other end of the strip-shaped trigger plate passes through the clearance slot and the trigger slot. The strip-shaped trigger plate has a first flat plate, a sloped transition plate, and a second flat plate arranged sequentially from one end to the other. The thickness of the first flat plate is greater than the thickness of the second flat plate. The first flat plate, the sloped transition plate, and the second flat plate are flush with each other on the side surface near the fixing seat. When the moving adjustment frame moves towards the fixing seat and the first flat plate passes through the trigger slot, it can drive the locking block to move away from the reset plate.

[0009] Furthermore, the synchronous tensioning assembly includes a tensioning plate, a tensioning drive, and a tensioning guide device. Multiple tensioning guide devices are evenly spaced along the length of the tensioning plate, and each tensioning guide device corresponds to one of the multiple cutting lines. Each tensioning guide device includes two second guide wheels and a tensioning wheel arranged in a triangular pattern. The cutting lines sequentially pass over one of the second guide wheels, the tensioning wheel, and the other tensioning wheel. The two second guide wheels are arranged side-by-side and rotatably mounted on a second fixed shaft, which is fixed to the upper end of the lifting frame. The second guide wheels are rotatably mounted on a third fixed shaft, which is fixed to the tensioning plate. The tensioning plate is laterally slidably connected to the upper end of the lifting frame via a third sliding assembly. The tensioning drive is located on the lifting frame and is used to drive the tensioning plate to slide laterally to adjust the distance between the tensioning wheel and the two second guide wheels. The tensioning drive includes two spaced-apart servo electric push rods.

[0010] Furthermore, two rollers are provided on both the left and right sides of the lifting frame. The two rollers are arranged vertically and located on the upper and lower sides of the cutting line, respectively. The rollers are rotatably mounted on the support base, and the support base is fixedly mounted on the upper end of the lifting frame.

[0011] Furthermore, there are four first sliding components, each located at one of the four corners of the lifting frame. Each first sliding component includes a first sliding rod and a first sliding sleeve. The first sliding rod is vertically arranged and fixedly mounted on the mounting frame. The first sliding sleeve is fixedly mounted on the lifting frame and is fitted onto the first sliding rod with a sliding engagement. There are two lifting drive mechanisms, symmetrically arranged on the left and right sides of the lifting frame. Each lifting drive mechanism includes a lifting servo motor, a transmission screw, and a slide table. The transmission screw is vertically arranged and rotatably mounted on the mounting frame. The lifting servo motor is fixedly mounted on a motor base, which is fixedly mounted on the upper end of the mounting frame. The motor shaft of the lifting servo motor is connected to one end of the transmission screw via a lifting coupling. The slide table is fixedly mounted on the lifting frame and is also fitted onto the transmission screw with a threaded engagement.

[0012] Furthermore, the stone clamping and placement mechanism includes a placement base plate and clamping side plates respectively located on the left and right sides of the placement base plate. The clamping side plates are detachably connected to the placement base plate by bolt assemblies. A clamping and placement cavity is formed between the two clamping side plates above the placement base plate. A flexible pad is fixedly provided on the side surface of the clamping side plate near the clamping and placement cavity. The clamping side plate is provided with a plurality of evenly spaced first clearance gaps for avoiding cutting lines. The placement base plate is provided with a plurality of evenly spaced second clearance gaps for avoiding cutting lines. The number of first clearance gaps and second clearance gaps is twice the number of cutting lines.

[0013] Furthermore, it also includes a base frame, a sliding plate, and a sliding drive mechanism. The mounting frame is fixedly installed at the middle of the upper end of the base frame. The sliding plate is installed at the upper end of the base frame and is laterally slidably connected to the base frame through a fourth sliding component. There are two stone clamping and placing mechanisms, which are spaced apart on the sliding plate. A cutting station is provided on the base frame within the mounting frame. Loading and unloading stations are provided on both sides of the mounting frame on the base frame. The sliding drive mechanism is installed on the base frame and is used to drive the sliding plate to slide laterally and to allow the two stone clamping and placing mechanisms to switch back and forth between the cutting station and the loading and unloading station. The sliding drive mechanism includes two spaced linear drive components.

[0014] As described above, the high-efficiency stone wire saw cutting equipment provided by this invention has the following beneficial effects: The stone clamping and placement mechanism facilitates stable clamping and placement of the stone body, effectively ensuring its stability during the cutting process; since the stone body's placement position is fixed, the lifting drive mechanism drives the lifting frame to descend slowly, thereby driving the wire saw cutting mechanism to descend slowly as well, achieving smooth cutting of the stone body; by setting multiple cutting lines and winding them in a U-shaped manner, each cutting line forms only two parallel and spaced cutting segments, greatly reducing the length of each cutting line pulled out, effectively reducing the cutting length... The probability of wire breakage is low, and repair after a breakage is relatively convenient; only the broken cutting wire needs to be replaced. Furthermore, because the cutting wire is wound in a U-shape, the two cutting segments on each wire move in opposite directions. This causes the forces applied to the stone during cutting to cancel each other out. The synchronous tensioning component facilitates the simultaneous tensioning of multiple cutting wires. Combined with the tension adjustment component, the tension adjustment component adjusts and balances the tension among the multiple cutting wires during the synchronous tensioning process, effectively ensuring the consistency of tension among the cutting wires and guaranteeing a stable and consistent cutting effect on the stone.

Detailed Implementation

[0025] The present invention will be further described below through specific embodiments.

[0026] like Figures 1 to 9 As shown, the high-efficiency stone wire saw cutting equipment of the present invention includes an installation frame 1, a lifting frame 2, a lifting drive mechanism 3, a stone clamping and placing mechanism 4, and a wire saw cutting mechanism 5. The lifting frame 2 is disposed within the installation frame 1 and is slidably connected to the installation frame 1 vertically via a first sliding component 21. The lifting drive mechanism 3 is disposed on the installation frame 1 and is used to drive the lifting frame 2 to move up and down. The stone clamping and placing mechanism 4 is disposed below the lifting frame 2 and is used to clamp and place the stone body 9. The wire saw cutting mechanism 5 is disposed on the lifting frame 2 and includes a cutting wire 51 and a first wire take-up and release component 5. 2. A second take-up and release assembly 53, a synchronous tensioning assembly 54, and a tension adjusting assembly 55. The two ends of the cutting wire 51 are respectively connected to the first take-up and release assembly 52 and the second take-up and release assembly 53. The synchronous tensioning assembly 54 and the tension adjusting assembly 55 are respectively located on the left and right sides of the lifting frame 2. The cutting wire 51 consists of multiple wires arranged in a U-shaped winding manner between the synchronous tensioning assembly 54 and the tension adjusting assembly 55. The synchronous tensioning assembly 54 is used to simultaneously tension the multiple cutting wires 51. The tension adjusting assembly 55 is used to adjust and balance the tension between the multiple cutting wires 51.

[0027] The stone clamping and placement mechanism 4 facilitates stable clamping and placement of the stone body 9, effectively ensuring its stability during the cutting process. Since the stone body 9 remains stationary, the lifting drive mechanism 3 drives the lifting frame 2 to descend slowly, which in turn drives the wire saw cutting mechanism 5 to descend slowly as well, enabling the wire saw cutting mechanism 5 to smoothly cut the stone body 9. By setting multiple cutting lines 51 and winding them in a U-shaped manner, each cutting line 51 forms only two parallel, spaced-apart cutting segments, significantly reducing the length of each cutting line 51 pulled out. This effectively reduces the probability of wire breakage, and repairs after a breakage are easier, requiring only... The broken cutting wire 51 can be replaced. Furthermore, since the cutting wire 51 is wound in a U-shape, the two cutting segments on each cutting wire 51 move in opposite directions. This causes the forces applied to the stone body 9 during cutting to cancel each other out. The synchronous tensioning component 54 facilitates the simultaneous tensioning of multiple cutting wires 51. In conjunction with the tension adjusting component 55, during the synchronous tensioning of multiple cutting wires 51 by the synchronous tensioning component 54, the tension adjusting component 55 can adjust and balance the tension among the multiple cutting wires 51, effectively ensuring the consistency of tension among the multiple cutting wires 51 and ensuring a stable and consistent cutting effect on the stone body 9.

[0028] Furthermore, preferably, the number of cutting lines 51 is 5-20.

[0029] The first take-up and release assembly 52 includes a first take-up and release motor 521, a first rotating shaft 522, a first take-up and release reel 523, and a first mounting base 524. The first rotating shaft 522 is rotatably mounted on the first mounting base 524 via a first bearing. The first mounting base 524 is fixedly mounted on the lifting frame 2. The first take-up and release motor 521 is fixedly mounted on the first mounting base 524. The motor shaft of the first take-up and release motor 521 is connected to one end of the first rotating shaft 522 via a first coupling. The first take-up and release reel 523 is fixedly installed on the first rotating shaft 522. The first take-up and release reel 523 is provided with a plurality of first take-up and release grooves 5231, and the plurality of first take-up and release grooves 5231 are arranged one-to-one with the plurality of cutting wires 51. Preferably, the first take-up and release motor 521 can be a servo motor. By controlling the forward and reverse rotation of the first take-up and release motor 521, the first rotating shaft 522 can be driven to rotate forward and reverse, so as to realize the take-up and release of the cutting wires 51 by the first take-up and release reel 523.

[0030] The second take-up and release assembly 53 includes a second take-up and release motor 531, a second rotating shaft 532, a second take-up and release wheel 533, and a second mounting base 534. The second rotating shaft 532 is rotatably mounted on the second mounting base 534 via a second bearing. The second mounting base 534 is fixedly mounted on the lifting frame 2. The second take-up and release motor 531 is fixedly mounted on the second mounting base 534. The motor shaft of the second take-up and release motor 531 is connected to one end of the second rotating shaft 532 via a second coupling. The second take-up and release reel 533 is fixedly installed on the second rotating shaft 532. The second take-up and release reel 533 is provided with a plurality of second take-up and release grooves 5331, and the plurality of second take-up and release grooves 5331 are arranged one-to-one with the plurality of cutting wires 51. Preferably, the second take-up and release motor 531 can be a servo motor. By controlling the forward and reverse rotation of the second take-up and release motor 531, the second rotating shaft 532 can be driven to rotate forward and reverse, so as to realize the take-up and release of the cutting wires 51 by the second take-up and release reel 533.

[0031] The tension adjustment assembly 55 includes an adjustment rope 551, fixed adjustment wheels 552, movable adjustment wheels 553, a first guide wheel 554, and a movable adjustment frame 555. Both ends of the adjustment rope 551 are fixedly mounted on corresponding fixed rods 556. The fixed rods 556 are fixedly mounted on the upper end of the lifting frame 2. Multiple fixed adjustment wheels 552 are evenly spaced and rotatably mounted on a first fixed shaft, which is fixedly mounted on the upper end of the lifting frame 2. A movable adjustment wheel 553 is positioned between adjacent fixed adjustment wheels 552. The adjustment rope 551 alternately winds around multiple fixed adjustment wheels 552 and multiple movable adjustment frames 555 in an S-shaped winding pattern. The movable adjusting wheel 553 is rotatably mounted on one end of the movable adjusting frame 555. The movable adjusting frame 555 is laterally slidably connected to the lifting frame 2 through the second sliding assembly 557. Two first guide wheels 554 are rotatably mounted on the other end of the movable adjusting frame 555, which are arranged vertically. The central axis of the first guide wheel 554 is perpendicular to the central axis of the movable adjusting wheel 553. The cutting line 51 passes between the two first guide wheels 554. The movable adjusting frame 555 is provided with a clearance notch 5551 for the cutting line 51 to pass through. The number of movable adjusting wheels 553 is twice the number of cutting lines 51.

[0032] Preferably, the adjusting rope 551 is a steel wire rope. Multiple fixed adjusting wheels 552 and multiple movable adjusting wheels 553 are connected in series using the adjusting rope 551 fixed at both ends. During the synchronous tensioning process of the synchronous tensioning assembly 54, under the combined action of the tension of the adjusting rope 551 and the tension of the cutting lines 51, the movable adjusting wheel 553 can automatically and adaptively slide laterally to adjust the lateral distance between the movable adjusting wheel 553 and two adjacent fixed adjusting wheels 552. The lateral distances between the multiple movable adjusting wheels 553 and two adjacent fixed adjusting wheels 552 are not necessarily the same, each compensating for the cutting length of the corresponding cutting line 51, and making the total cutting length of the multiple cutting lines 51 approximately consistent with the sum of the overall lengths of the corresponding lateral distances. This ultimately adjusts the tension of the multiple cutting lines 51 after tensioning and makes their tension approximately consistent, thereby effectively ensuring the consistency and stability of the cutting effect of the multiple cutting lines 51 on the stone body 9.

[0033] Correspondingly, the second sliding component 557 includes a second slide rail and a second slider. The second slide rail is fixedly installed on the upper end of the lifting frame 2, and the second slider is fixedly installed on the bottom end of the moving adjustment frame 555. The second slider is adapted to the second slide rail and the two slide in a sliding fit. The lifting frame 2 is provided with second limit blocks at both ends of the second slide rail. In this way, the stability and smoothness of the moving adjustment frame 555 during sliding are effectively ensured.

[0034] The wire saw cutting mechanism 5 further includes multiple elastic tension reset components 56, each corresponding to one of the multiple movable adjustment frames 555. Each elastic tension reset component 56 includes a fixed base 561, a first compression spring 562, a reset plate 563, a second compression spring 564, a locking block 565, a fixed sleeve 566, a sealing plate 567, and a trigger element 568. The fixed base 561 is fixedly installed on the upper end of the lifting frame 2 and located on one side of the movable adjustment frame 555. The fixed base 561 has a first cavity open to one side of the movable adjustment frame 555. The cavity contains, from the inside out, a first compression spring 562 and a reset plate 563. The reset plate 563 is square-shaped and fits the first cavity. One end of the first compression spring 562 is fixedly connected to the fixing base 561, and the other end is fixedly connected to the reset plate 563. The left and right side walls of the fixing base 561 have through holes. The fixing sleeves 566 are fixedly installed on the outer surfaces of the left and right sides of the fixing base 561 at the through holes. Each fixing sleeve 566 has a second cavity penetrating both ends and communicating with the through holes. The locking block 565 fits into the through holes and... The locking block 565 is slidably inserted into the perforation. One end of the locking block 565 is detachably engaged with the edge of one side surface of the reset plate 563. Positioning protrusions 5651 located in the second cavity are fixedly provided on both sides of the other end of the locking block 565. The sealing plate 567 is fixedly installed at the outer opening of the fixing sleeve 566. At least one second compression spring 564 is also provided in the second cavity. One end of the second compression spring 564 abuts against the locking block 565, and the other end abuts against the sealing plate 567. The trigger 568 is provided on the movable adjustment frame 555. There are two trigger elements 568, which are arranged one-to-one with the two fixed sleeves 566. When the movable adjustment frame 555 moves to the corresponding trigger position on the side of the fixed seat 561, it can drive the trigger element 568 to trigger the locking block 565 to perform an action and move one end of the locking block 565 away from the reset plate 563 to release the locking limit on the reset plate 563. At this time, under the elastic force of the first compression spring 562, the reset plate 563 can be pushed to move towards the side of the movable adjustment frame 555 and push the movable adjustment frame 555 to move away from the fixed seat 561 to reset.

[0035] Correspondingly, the trigger element 568 is a strip-shaped trigger plate, the locking block 565 has a trigger slot 5652, the fixing sleeve 566 has an clearance slot 5661, one end of the strip-shaped trigger plate is fixed to the moving adjustment frame 555, and the other end of the strip-shaped trigger plate passes through the clearance slot 5661 and the trigger slot 5652. The strip-shaped trigger plate has a first flat plate 5681, a sloped transition plate 5682, and a second flat plate 5683 sequentially arranged from one end to the other. The thickness of the first flat plate 5681 is greater than the thickness of the second flat plate 5683. The first flat plate 5681, the inclined transition plate 5682 and the second flat plate 5683 are flush with each other on the side surface near the fixed seat 561. When the movable adjustment bracket 555 moves toward the fixed seat 561 and the first flat plate 5681 passes through the trigger slot 5652, it can drive the locking block 565 to move away from the reset plate 563.

[0036] During the cutting process of the stone body 9, if one of the cutting lines 51 breaks unexpectedly, and because the pulling effect of that cutting line 51 on the corresponding moving adjustment frame 555 is no longer present, and under the tension of the remaining cutting lines 51 and the linkage effect of the adjustment rope 551, the corresponding moving adjustment frame 555 will move towards the fixed seat 561. When it moves to the corresponding trigger position, at the same time, the contact position between the strip trigger plate and the locking block 565 will move from the second flat plate 5683 to the first flat plate 5681. Since the thickness of the first flat plate 5681 is greater than the thickness of the second flat plate 5683, this can bring... One end of the movable locking block 565 is moved away from the reset plate 563, thereby releasing the locking block 565 from the reset plate 563. At this time, under the elastic force of the first compression spring 562, the reset plate 563 can be pushed to the side of the movable adjustment frame 555 and the movable adjustment frame 555 can be pushed to the side away from the fixed seat 561 to reset. Thus, under the linkage of the adjustment rope 551, the other movable adjustment frames 555 can be moved and reset accordingly, so as to restore the original tension of the other multiple cutting lines 51 as much as possible, thereby ensuring the stable cutting use of the other multiple cutting lines 51 as much as possible.

[0037] The synchronous tensioning assembly 54 includes a tensioning plate 541, a tensioning drive component 542, and a tensioning guide device 543. Multiple tensioning guide devices 543 are evenly spaced along the length of the tensioning plate 541. Each tensioning guide device 543 corresponds to one of the multiple cutting lines 51. Each tensioning guide device 543 includes two second guide wheels 5431 arranged in a triangle and a tensioning wheel 5432. The cutting lines 51 sequentially pass over one of the second guide wheels, the tensioning wheel 5432, and the other tensioning wheel 5432. The two second guide wheels 5431 are arranged side-by-side and rotatably mounted on a second fixed shaft, which is fixed to the upper end of the lifting frame 2. The second guide wheels 5431 are also rotatably mounted on a third fixed shaft, which is fixed to the tensioning plate 541. The tensioning plate 541 is connected to a third sliding assembly. The tensioning drive component 544 is laterally slidably connected to the upper end of the lifting frame 2. The tensioning drive component 542 is disposed on the lifting frame 2 and is used to drive the tensioning plate 541 to slide laterally to adjust the interval distance between the tensioning wheel 5432 and the two second guide wheels. The tensioning drive component 542 includes two spaced servo electric push rods. The servo electric push rods are equipped with servo motors and are driven by the servo motors to extend and retract, which can achieve precise control of the motion trajectory. When it is necessary to simultaneously tension multiple cutting lines 51, the tensioning plate 541 is driven to slide away from the second guide wheel 5431 by the servo electric push rods. This can drive multiple tensioning wheels 5432 to slide synchronously, thereby increasing the distance between the tensioning wheel 5432 and the corresponding two second guide wheels. This can increase the overall winding stroke of the cutting line 51 and achieve synchronous tensioning of multiple cutting lines 51.

[0038] The third sliding component 544 includes a third slide rail and a third slider. The third slide rail is fixedly installed on the upper end of the lifting frame 2, and the third slider is fixedly installed on the bottom end of the tension plate 541. The third slider is adapted to the third slide rail and the two slide in a sliding fit. The third limiting block is fixedly provided on both ends of the third slide rail on the lifting frame 2, thereby effectively ensuring the stability and smoothness of the tension plate 541 when sliding.

[0039] In addition, two rollers 57 are provided on both the left and right sides of the lifting frame 2. The two rollers 57 are arranged vertically and respectively on the upper and lower sides of the cutting line 51. The rollers 57 are rotatably mounted on the support base 58, and the support base 58 is fixedly mounted on the upper end of the lifting frame 2. This can play a certain limiting role in the vertical direction of the two sides of the cutting line 51, effectively avoiding the situation where the cutting line 51 accidentally falls off the second guide wheel due to the line bow angle caused by the stone body 9 being lifted during the cutting process. This is conducive to further ensuring the stability of the cutting line 51 during the cutting process.

[0040] Correspondingly, there are four first sliding components 21, which are respectively located at the four corners of the lifting frame 2. Each first sliding component 21 includes a first sliding rod 211 and a first sliding sleeve 212. The first sliding rod 211 is arranged vertically and fixedly mounted on the mounting frame 1. The first sliding sleeve 212 is fixedly mounted on the lifting frame 2. The first sliding sleeve 212 is sleeved on the first sliding rod 211 and the two slide together, thereby effectively ensuring the stability and smoothness of the lifting frame 2 when it is raised and lowered.

[0041] The lifting drive mechanism 3 consists of two symmetrically arranged on the left and right sides of the lifting frame 2. Each lifting drive mechanism 3 includes a lifting servo motor 31, a transmission screw 32, and a slide 33. The transmission screw 32 is vertically arranged and rotatably mounted on the mounting frame 1. The lifting servo motor 31 is fixedly mounted on a motor base 34, which is fixedly mounted on the upper end of the mounting frame 1. The motor shaft of the lifting servo motor 31 is connected to one end of the transmission screw 32 via a lifting coupling. The slide 33 is fixedly mounted on the lifting frame 2 and is also sleeved on the transmission screw 32, with the two being threadedly connected. Thus, by controlling the forward and reverse rotation of the lifting servo motor 31, the transmission screw 32 can be driven to rotate forward and reverse. Utilizing the threaded connection between the slide 33 and the transmission screw 32, and with the guiding effect of the first sliding component 21, the sliding 33 can be raised and lowered, thereby driving the lifting frame 2 to rise and fall.

[0042] The stone clamping and placing mechanism 4 includes a placing base plate 41 and clamping side plates 42 respectively disposed on the left and right sides of the placing base plate 41. The clamping side plates 42 are detachably connected to the placing base plate 41 by bolt assemblies 43. A clamping and placing cavity 45 is formed between the two clamping side plates 42 above the placing base plate 41. A flexible pad 44 is fixedly provided on the side surface of the clamping side plate 42 near the clamping and placing cavity 45. Preferably, the flexible pad 44 is a rubber pad. The clamping side plate 42 is provided with a plurality of evenly spaced first avoidance gaps 421 for avoiding the cutting line 51. The placing base plate 41 is provided with a plurality of The first and second avoidance gaps 421 and the second avoidance gaps 411 are evenly spaced and used to avoid the cutting line 51. The number of the first and second avoidance gaps 421 and the second avoidance gaps 411 is twice the number of the cutting line 51. By setting the first and second avoidance gaps 421 and the second avoidance gaps 411, the cutting of the cutting line 51 can be avoided, allowing the cutting line 51 to cut through the bottom end of the stone body 9. By setting the clamping and placing cavity 45, the stone body 9 can play a good clamping and fixing role during and after the cutting process, effectively ensuring the placement stability of the stone body 9 during and after the cutting process.

[0043] Correspondingly, the bolt assembly 43 includes a locking bolt and an anti-loosening washer. The clamping side plate is provided with multiple through holes, and the left and right sides of the placement base plate are provided with multiple threaded holes. The locking bolt passes through the anti-loosening washer and the through holes in sequence and is then threadedly connected to the threaded holes.

[0044] The high-efficiency stone wire saw cutting equipment also includes a base frame 6, a sliding plate 7, and a sliding drive mechanism 8. The mounting frame 1 is fixedly installed at the upper middle part of the base frame 6. The sliding plate 7 is installed at the upper end of the base frame 6 and is laterally slidably connected to the base frame 6 through a fourth sliding component 71. There are two stone clamping and placing mechanisms 4, which are spaced apart on the sliding plate 7. The base frame 6 has a cutting station inside the mounting frame 1. The base frame 6 has loading and unloading stations on both sides of the mounting frame 1. The sliding drive mechanism 8 is installed on the base frame 6 and is used to drive the sliding plate 7 to slide laterally and to allow the two stone clamping and placing mechanisms 4 to switch back and forth between the cutting station and the loading and unloading station. The sliding drive mechanism 8 includes two spaced linear drive components. Preferably, the linear drive components are hydraulic cylinders, air cylinders, or electric push rods.

[0045] The linear drive component drives the sliding plate 7 to slide laterally, allowing the two stone clamping and placing mechanisms 4 to switch back and forth between the cutting station and the loading / unloading station. In this way, the stone body 9 to be cut can first be loaded and installed at the loading / unloading station. After the stone body 9 at the cutting station is cut, the sliding plate 7 is driven to slide laterally, thereby moving the cut stone body 9 at the cutting station to the loading / unloading station for unloading. At the same time, the stone body 9 to be cut, which was originally at the loading / unloading station, can be moved to the cutting station to prepare for cutting, thereby further improving the overall production efficiency.

[0046] Preferably, there are two fourth sliding components 71 arranged at intervals. Each fourth sliding component 71 includes a fourth slide rail and a fourth slider. The fourth slide rail is fixedly installed on the upper end of the base frame 6. Multiple fourth sliders are fixedly installed at intervals on the lower end of the sliding plate 7. The fourth sliders are adapted to the fourth slide rail and slide in cooperation with it. Fourth limiting blocks are fixedly provided on both ends of the fourth slide rail on the base frame 6. In this way, the stability and smoothness of the sliding plate 7 during sliding are effectively ensured.

[0047] In addition, a spray cooling mechanism is fixedly installed at the top of the mounting frame 1 above the lifting frame 2. The spray cooling mechanism includes multiple spray pipes spaced apart. The spray pipes are connected to an external water supply device. Multiple nozzles are spaced apart along the length of the spray pipes, which can provide a corresponding spray cooling effect for the cutting process of the stone body 9. The spray cooling mechanism can adopt the structure in the prior art, so it will not be described in detail here. A water collection tank is fixedly installed at the bottom of the mounting frame 1 below the lifting frame 2.

[0048] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
