Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a vertical arc-shaped stone cutting device. Background Technology

[0002] In the stone processing industry, wire saws are widely used in various stone cutting operations due to their advantages such as flexible cutting and narrow kerf. Existing wire saws typically adopt a frame structure with guide wheels, using a high-speed rotating cutting rope to achieve linear or curved cutting of stone. They can adapt to different shape cutting needs and have become an important piece of equipment in modern stone processing.

[0003] For example, the arc-shaped wire saw disclosed in application number 202410292665.8 uses a gantry-suspended moving frame structure, which has obvious structural stability problems. Specifically, although the moving frame moves based on the gantry, its bottom is suspended during cutting operations, causing the cutting rope to easily vibrate longitudinally during high-speed cutting, making it difficult to maintain a stable cutting trajectory. This structural defect reduces the reliability of the equipment under long-term high-load operation, restricting its application in the field of precision stone processing. Utility Model Content

[0004] To address the shortcomings mentioned above in the background technology, this utility model provides a vertical arc-shaped stone cutting device.

[0005] The present invention adopts the following technical solution: A vertical curved stone cutting device includes: A conveying platform for transporting stone, wherein the conveying surface of the conveying platform forms a sawing gap; A moving device is disposed on one side of the conveying platform, the moving device including a moving base, the moving base moving laterally relative to the sawing gap; A sawing device is disposed on the movable seat, the sawing device comprising: A sawing frame, which is fixed to the movable seat, has a cutting channel on the side of the sawing frame facing the conveying platform, and the cutting channel is vertically opposite to the upper and lower ends of the sawing gap; Several guide wheels are arranged inside the sawing frame; A wire saw, which is wound around each of the guide wheels, forms a vertical cutting segment at the cutting channel; A first motor is fixed to the side of the sawing frame away from the conveying platform. The first motor drives one of the guide wheels to rotate, thereby driving the wire saw to operate. When the movable seat moves the sawing frame, the cutting section of the operating wire saw enters the sawing gap and moves relative to the conveying platform.

[0006] In one possible implementation, the conveying platform includes a frame, rollers, a conveyor belt, and a second motor. Several rotatable rollers are arranged along the length of the frame. At least two sections of conveyor belt are provided on the frame, with a sawing gap formed between the two sections. At the positions of the two sections of conveyor belt, the conveyor belt passes around the rollers at both ends of the position to form a closed loop, and the upper portion of the conveyor belt is laid on each roller, so that the rollers support the upper portion of the conveyor belt.

[0007] In one possible implementation, the conveying platform further includes a drive shaft that is restricted to rotating on one side of the frame, and the second motor drives the drive shaft to rotate; a plurality of drive gears are fixed on the drive shaft, and a driven gear is fixed at one end of the roller shaft, the drive gears and the driven gears meshing.

[0008] In one possible implementation, the sawing frame has guide wheels installed at both the upper and lower ends of the cutting channel, and a limiting wheel is installed on one side of the guide wheels at both ends of the cutting channel near one end of the cutting channel. The wire saw passes between the guide wheels and the limiting wheel to form the cutting segment.

[0009] In one possible implementation, the moving device further includes a base, a lead screw, and a third motor. The lead screw is mounted on the base and rotates. The third motor is fixed outside the base and drives the lead screw to rotate. The moving seat is connected to the base and slides on it. The bottom surface of the moving seat is helically connected to the lead screw.

[0010] In one possible implementation, the base has slide rails fixed at both ends of the lead screw, and both slide rails are adapted to connect to sliders, which are fixed to the bottom surface of the movable seat.

[0011] In one possible implementation, the mobile device further includes a protective cover, the mobile seat is provided with clearance openings extending through both ends, the base is fixed with baffles at both ends in the sliding direction of the mobile seat, the protective cover passes through the clearance openings and is fixed to the two baffles, so that the protective cover covers the base.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: The sawing device adopts a rigid connection fixed to the moving base, so that the sawing frame and the moving base form a vertical integral structure, fundamentally avoiding the vibration problem caused by the suspension design. Combined with the stable support at the cutting channel, it effectively suppresses the swaying of the wire saw during high-speed cutting. This integrated structural design ensures that the entire sawing device maintains a stable motion trajectory during movement, greatly improving cutting accuracy and equipment reliability, and is especially suitable for stone cutting operations with high precision requirements.

[0023] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0024] This utility model provides a vertical arc-shaped stone cutting device, as shown in the attached figure. Figure 1 and 2 As shown, the equipment includes a conveying platform 1, a moving device 2, and a sawing device 3. The conveying platform 1 is used to convey stone, and the conveying surface of the conveying platform 1 forms a sawing gap 101. The moving device 2 is located on one side of the conveying platform 1, and the moving device 2 drives the sawing device 3 to move relative to the sawing gap 101, so as to cut the stone conveyed on the conveying platform 1.

[0025] As attached Figure 3 and 4 As shown, the conveying platform 1 includes a frame 11, rollers 12, conveyor belts 13, and a second motor 14. Several rotatable rollers 12 are arranged at intervals along the length of the frame 11. Specifically, bearing seats are fixed on both sides of the frame 11, and the ends of the rollers 12 are axially positioned and restricted to a rotatable state by the bearing seats fixed to both sides of the frame 11. At least two sections of conveyor belt 13 are arranged on the frame 11 along its conveying direction, forming a sawing gap 101 between the two sections. At the positions of the two sections of conveyor belt 13, the conveyor belt 13 bypasses the rollers 12 at both ends of that position to form a closed loop, and the upper portion of the conveyor belt 13 is laid on each roller 12. The rotational support of the rollers 12 ensures the stable operation of the conveyor belt 13, thus reliably supporting the stone during the conveying process. This structural design ensures the smooth operation of the stone during the conveying process, while providing unobstructed cutting space for the sawing device 3, effectively improving the continuity and processing accuracy of the arc cutting. Furthermore, a support plate is fixed inside the frame 11 in the gap between each pair of adjacent rollers 12 near the sawing gap 101 on both sides, to assist in supporting the stone during transportation.

[0026] The conveying platform 1 also includes a drive shaft 15. Bearing seats are fixed at both ends of one side of the frame 11, and both ends of the drive shaft 15 are respectively fixed to the two bearing seats on the sides of the two frames 11, restricting the drive shaft 15 to rotate only on the sides of the frame 11. Several drive gears 151 are fixed on the drive shaft 15, and a driven gear 121 is fixed to one end of the roller shaft 12. The drive gears 151 and driven gears 121 mesh, so that when the drive shaft 15 rotates, it synchronously drives the roller shafts to rotate, thereby driving the conveyor belt 13 to run stably. Preferably, both the drive gear 151 and the driven gear 121 are helical gears. A second motor 14 is fixed to the frame 11, and the second motor 14 drives the drive shaft 15 to rotate, realizing fully automatic synchronous operation of the two conveyor belts 13. This design ensures efficient and reliable power transmission during stone conveying, effectively reduces operating vibration, and significantly improves the automation level and processing stability of stone cutting. Preferably, the drive connection structure between the second motor 14 and the drive shaft 15 can be a gear drive or a chain drive.

[0027] As attached Figure 5 and 6 As shown, the moving device 2 includes a base 21, a moving seat 22, a lead screw 23, and a third motor 24. The base 21 is located on one side of the sawing gap 101 of the conveying platform 1. Both ends of the base 21 are fixed with baffles 211. The two ends of the lead screw 23 are respectively connected to bearing seats fixed to the two baffles 211, thus axially restricting the lead screw 23 to rotate on the base 21. The third motor 24 is fixed to the side of one of the baffles 211 located outside the base 21 to drive the lead screw 23 to rotate. Slide rails 251 are also fixed to both ends of the lead screw 23 on the base 21. Both slide rails 251 are adapted to connect sliders 252, which are fixed to the bottom surface of the moving seat 22, thereby restricting the moving seat 22 to slide directionally along the slide rails 251 on the base 21. Simultaneously, the bottom surface of the moving seat 22 and the lead screw 23 are helically connected. When the third motor 24 drives the lead screw 23 to rotate, it can drive the moving seat 22 to perform a lateral feed motion relative to the sawing gap 101. Preferably, the bottom surface of the movable seat 22 forms a helical transmission pair with the lead screw 23 through the nut support. The radial movement is effectively eliminated through the transmission of the lead screw 23 and the guidance of the slide rail 251, which significantly improves the trajectory control accuracy of the movable seat 22 and the reliability of the equipment.

[0028] As attached Figure 7As shown, the sawing device 3 includes a sawing frame 31, guide wheels 32, a wire saw 33, and a first motor 34. The sawing frame 31 is fixed to the movable base 22. The side of the sawing frame 31 facing the conveyor platform 1 has a C-shaped cutting channel 311. The cutting channel 311 is vertically aligned with the upper and lower ends of the sawing gap 101. That is, after the sawing frame 31 moves towards the sawing gap 101, the cutting channel 311 can span the upper and lower surfaces of the conveyor belt 13, thus forming a vertical, movable structure. Several guide wheels 32 are arranged inside the sawing frame 31. Guide wheels 32 are also provided at both the upper and lower ends of the cutting channel 311 inside the sawing frame 31, and at the end of the sawing frame 31 furthest from the conveyor platform 1 (i.e., furthest from the cutting channel 311). The wire saw 33 is wound around each guide wheel 32, so that the wire saw 33 forms a vertically extending cutting segment at the cutting channel 311. The first motor 34 is fixed to the side of the sawing frame 31 away from the conveying platform 1, and the output shaft of the first motor 34 is connected and fixed to the guide wheel 32 at that position to drive the guide wheel 32 to rotate, thereby driving the wire saw 33 to operate continuously to achieve efficient sawing. Furthermore, a limiting wheel 35 is added to one side of the guide wheel 32 at both ends of the cutting channel 311 near one end of the cutting channel 311. The wire saw 33 passes between the guide wheel 32 and the limiting wheel 35 to form a cutting section. The synergistic constraint of the limiting wheel 35 and the guide wheel 32 effectively suppresses the swing of the wire saw 33, ensuring the perpendicularity of the cutting surface and the processing stability, and greatly enhancing the equipment's ability to process complex stone.

[0029] During operation, while the moving seat 22 drives the cutting section to enter the sawing gap 101 to perform a transverse cutting motion, the conveying platform 1 simultaneously drives the stone to move along the forward direction. Through the coordinated control of the two, the cutting section forms a continuous and gradually changing arc-shaped cut inside the stone. After the cutting section moves to the middle position in the width direction of the stone, the conveying platform 1 switches to reverse driving the stone to move backward. At the same time, the moving seat 22 continues to drive the cutting section to move laterally. Through the precise coordination between the spatial trajectory of the cutting section and the reciprocating motion of the stone, a high-precision arc-shaped surface is finally formed on one side of the stone.

[0030] As can be seen from the above structure, the sawing device 3 adopts a rigid connection fixed to the moving base 22, making the sawing frame 31 and the moving base 22 form a vertical integral structure, fundamentally avoiding the vibration problem caused by the suspension design. Combined with the stable support at the cutting channel, it effectively suppresses the swaying of the wire saw 33 during high-speed cutting. This integrated structural design ensures that the entire sawing device 3 maintains a stable motion trajectory during movement, significantly improving cutting accuracy and equipment reliability, especially suitable for high-precision curved stone cutting operations. Further, refer to the attached... Figure 8A C-shaped frame 27 can be installed and fixed on one side of the sawing frame 31 on the movable base 22. The sawing frame 31 is fixed to one side of the frame 27 to improve the overall rigidity of the sawing frame 31.

[0031] Please refer to the appendix. Figure 9 A support plate 36 is fixed to one end of the sawing frame 31 away from the cutting channel 311. This support plate can also be fixed to the frame. An adjustment seat 37 that can slide along a straight trajectory is installed on the support plate 36. Specifically, the adjustment seat 37 and the support plate 36 can also slide through a slide rail slider assembly. The first motor 34 is fixed to the adjustment seat 37. The support plate 36 also fixes an adjustment cylinder 38, which is preferably a hydraulic cylinder. The end of the telescopic rod of the adjustment cylinder 38 is fixed to a sliding block on the adjustment seat 37. The telescopic movement of the adjustment cylinder 38 drives the adjustment seat 37 to drive the first motor 34 and the corresponding guide wheel 32 to move along the slide rail 251, realizing real-time and precise control of the tension of the wire saw 33 during the cutting process. This ensures smooth operation of the wire saw 33 during the tension adjustment process, effectively avoids the risk of cutting deviation or breakage caused by the slack of the wire saw 33, significantly improves the stability and reliability of continuous operation of the equipment, and reduces the frequency of manual intervention, adapting to the tension adaptive requirements under different cutting conditions.

[0032] In addition, as attached Figure 6 and 7 As shown, the mobile device 2 also includes a protective cover 26. The mobile base 22 is provided with clearance openings 221 extending through both ends. Baffles 211 are fixed to both ends of the base 21 in the sliding direction of the mobile base 22. The protective cover 26 has an overall elongated structure and extends through the clearance openings 221 of the mobile base 22. Its two ends are fixed to the baffles 211 at both ends of the base 21, forming a closed protective enclosure for the internal screw 23 transmission mechanism and the guide structure of the slide rail 251 and slider 252 within the base 21. This protective cover 26 achieves dynamic cooperation with the mobile base 22 through the through-hole clearance design. While ensuring the normal sliding stroke of the mobile base 22, it effectively prevents external dust, gravel, and other foreign objects from intruding into the precision transmission components, significantly improving the operational reliability of the equipment under harsh working conditions. It also reduces mechanical wear and extends the service life of key components. Furthermore, the overall structure is simple and compact, requiring no additional equipment space.

[0033] In summary, the device of this utility model includes a conveying platform 1, a moving device 2, and a sawing device 3. The conveying platform 1 is provided with at least two conveyor belts 13 for conveying stone, and a transverse sawing gap 101 is formed between the two conveyor belts 13. The moving device 2 is located on the side of the sawing gap 101. The sawing frame 31 of the sawing device 3 is fixed to the moving base 22 to form a vertical rigid structure. The sawing frame 31 has a cutting channel 311 aligned with the sawing gap 101. Guide wheels 32 are arranged inside the sawing frame 31. Guide wheels 32 are provided at the upper, lower and far ends of the cutting channel 311. The wire saw 33 is wound around each guide wheel 32 and forms a vertical cutting section in the cutting channel 311. The first motor 34 drives the far-end guide wheel 32 to drive the wire saw 33 to rotate. During operation, the moving seat 22 drives the cutting section to laterally penetrate the sawing gap 101, while the conveying platform 1 synchronously drives the stone forward to form an arc-shaped cut. After the cutting section reaches the middle of the stone, the conveying platform 1 switches to reverse and retreats, while the moving seat 22 continues to move laterally. Through bidirectional coordinated motion, a high-precision arc-shaped surface is precisely formed on one side of the stone. This dynamic cutting method significantly improves the processing efficiency of complex curved surfaces. The bidirectional coordinated feed mechanism effectively eliminates the trajectory error caused by the unidirectional cutting of traditional equipment, ensuring the continuity of curvature and dimensional consistency of the arc-shaped surface, while greatly reducing the equipment's idle time.

[0034] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
