Description

Technical Field

[0001] This application belongs to the field of stone processing technology, specifically relating to a stone cutting device. Background Technology

[0002] In fields such as architectural decoration, municipal engineering, and stone processing, stone cutting is the core link in stone forming and processing. Its processing quality and efficiency directly affect the progress of subsequent processes and the quality of the final product. Existing stone cutting equipment often uses fixed parameter modes or relies on manual experience for feed control. Traditional semi-automatic equipment typically achieves a single feed speed setting through preset mechanical transmission ratios or simple electrical controls. Once cutting begins, the stone's feed speed remains constant and cannot be dynamically adjusted according to real-time cutting conditions. For example, when encountering uneven stone hardness, differences in saw blade wear, or variations in cutting depth during the cutting process, a fixed feed speed is difficult to match the actual cutting requirements. Specifically, when the stone has a high local hardness or the saw blade edge shows slight wear, maintaining the original feed speed will cause a sudden increase in cutting resistance, leading to fluctuations in the feed speed. These fluctuations directly result in uneven force on the cut surface, causing chipping, burrs, or wavy patterns, severely affecting the flatness of the cut surface. Subsequent grinding and polishing are required to compensate for this, significantly increasing process costs and time. More seriously, if the feed speed is too high and not adjusted in time, excessive cutting resistance can cause the saw blade to jam, potentially leading to permanent damage such as chipped teeth and deformation. It can also cause equipment shutdown or even electrical failure due to motor overload, posing a significant safety hazard. Conversely, to avoid the aforementioned problems, operators often choose a conservative low feed rate. While this can ensure cutting stability to some extent, it sacrifices cutting efficiency. Especially when processing homogeneous stone in batches, a fixed low-speed mode will significantly reduce the amount of material cut per unit time, resulting in insufficient equipment capacity utilization and making it difficult to meet the efficiency requirements of large-scale production.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0024] Example 1: Please see the appendix Figure 1-3 The stone cutting device of this application includes a cutting mechanism 1, a pushing mechanism 2 and a limiting mechanism 3. The cutting mechanism 1 is used to cut the stone 6; the pushing mechanism 2 includes a pushing component 21 and a platform 22, the platform 22 is provided with a storage area 23, the storage area 23 is located between the pushing component 21 and the cutting mechanism, and the storage area 23 is used to place the stone 6 to be cut; the limiting mechanism 3 is located on both sides of the cutting mechanism 1, and is used to limit the stone 6 to be cut; the pushing component 21 includes a first cylinder 211, a pushing component 212 and a pressure sensor 213, the driving end of the first cylinder 211 is drivenly connected to the pushing component 212, one side of the pressure sensor 213 is connected to the pushing component 212, the sensing surface of the pressure sensor 213 abuts against the stone 6, and the first cylinder 211 is electrically connected to the pressure sensor 213; the pressure sensor 213 is used to sense the pressure fluctuation of the stone 6 in the cutting state, and the first cylinder 211 is used to control the speed at which the pushing component 212 pushes the stone 6 through the pressure fluctuation obtained by the pressure sensor 213.

[0025] Among them, the cutting mechanism 1 refers to the mechanical unit that performs the stone 6 splitting operation. Specifically, it can be realized by using a diamond circular saw blade in combination with a drive motor to complete the stone 6 processing through rotary cutting.

[0026] Pressure sensor 213 refers to the sensing element that detects the contact pressure between the stone 6 and the cutting tool. Specifically, it can be implemented by a piezoelectric sensor or a strain gauge sensor. Its sensing surface maintains continuous contact with the side of the stone 6 through an elastic contact element.

[0027] The first cylinder 211 refers to the power device that drives the stone 6 forward. Specifically, it can be implemented by using a double-acting cylinder in conjunction with a proportional control valve, which adjusts the extension and retraction speed of the piston rod by receiving pressure signals.

[0028] In this embodiment, the stone cutting device has a platform 22 positioned between the advancing component and the cutting tool to form a buffer zone. After the stone 6 is placed, its lateral displacement is constrained by the limiting mechanism 3. A pressure sensor 213 collects the dynamic pressure experienced by the stone 6 during the cutting process in real time, converting pressure fluctuations into electrical signals that are transmitted to the cylinder control system. When an abnormal increase in pressure is detected, the cylinder automatically reduces its advancing speed to decrease cutting resistance; when the pressure is within a stable range, the cylinder maintains the optimal advancing speed. This dynamic adjustment mechanism ensures that the stone 6 is always in a stable cutting state, avoiding processing defects caused by speed mismatch.

[0029] This solution forms a closed-loop speed control through pressure feedback, effectively eliminating cutting surface defects caused by uneven stone material 6, preventing equipment failures caused by abnormal wear of the saw blade, and improving processing efficiency by dynamically optimizing the feed speed while ensuring cutting quality. It eliminates the lag of manual intervention, reduces downtime for adjustment, and avoids the limitations of a single speed mode. It is suitable for continuous processing scenarios of heterogeneous stones 6 such as marble and granite.

[0030] In some embodiments, the first cylinder 211 is disposed opposite to the cutting mechanism 1; the pusher 212 includes a connecting plate 214 and a pusher block 215, the pusher block 215 is vertically connected to both sides of the connecting plate 214, and the pressure sensor 213 is connected to the pusher block 215.

[0031] The connection of the pressure sensor 213 to the push block 215 means that the sensor body is installed on the front end of the push block 215 by means of threaded connection or snap-fit. Specifically, it can be achieved by embedded installation so that the sensing surface is flush with the end face of the push block 215. This arrangement allows the pressure fluctuation generated by the contact surface of the stone 6 to be directly transmitted to the sensor, shortening the signal transmission path.

[0032] Specifically, the connecting plate 214 and the vertically arranged pushing blocks 215 on both sides form a dual-sided synchronous force-applying structure. When the stone 6 is pushed, the pushing blocks 215 on both sides simultaneously apply a pushing force to the stone 6 in the direction of the cutting mechanism 1, thereby pushing the stone 6 to the cutting mechanism 1 for cutting. The distribution of the pushing blocks 215 can keep the stone 6 under force balance during the pushing process, avoiding lateral displacement caused by unilateral force application. The pressure sensor 213 is directly installed at the front end of the pushing block 215. When its sensing surface contacts the stone 6, the dynamic pressure changes generated during the cutting process are directly transmitted to the sensor through the pushing block 215 without going through intermediate transmission components, ensuring the real-time and accurate acquisition of pressure signals.

[0033] The dual-sided synchronous force application structure eliminates the risk of lateral displacement and effectively maintains the force balance during the stone advancement process. At the same time, the pressure sensor is directly integrated into the force application component to capture the cutting resistance change signal in real time, realize the real-time accurate detection of cutting resistance, and provide instant data support for cylinder speed adjustment, thereby improving the stability of the cutting surface quality and reducing abnormal equipment wear.

[0034] In some embodiments, the storage area 23 is provided with a plurality of evenly spaced first omnidirectional balls 231, which are embedded in the storage table 22.

[0035] Among them, the first omnidirectional ball 231 refers to a spherical structural component with omnidirectional rolling function, which can be made of stainless steel with a smooth surface. "Embedded in the shelf 22" means that the omnidirectional ball is embedded in the main structure of the shelf 22, which can be achieved by using a countersunk hole and a limiting ring to keep the top of the omnidirectional ball flush with the surface of the shelf 22.

[0036] Specifically, when the stone 6 moves within the storage area 23, the omnidirectional balls counteract the sliding friction between the stone 6 and the storage platform 22 through free rolling, creating a point-contact rolling friction state between the bottom surface of the stone 6 and the omnidirectional balls. The equidistantly distributed omnidirectional balls continuously provide uniformly distributed support points during the movement of the stone 6, ensuring that the rolling friction resistance experienced by each area of ​​the bottom surface of the stone 6 becomes consistent. The installation structure of the omnidirectional balls embedded in the storage platform 22 prevents direct contact between the stone 6 and the surface of the storage platform 22 during movement. Simultaneously, the material of the storage platform 22 provides rigid support for the omnidirectional balls, preventing them from sinking or shifting when bearing the weight of the stone 6.

[0037] By converting sliding friction into rolling friction through the universal balls, the feed speed fluctuations caused by uneven frictional resistance during the movement of the stone 6 are effectively eliminated. This allows the pressure sensor 213 to accurately detect the actual pressure changes of the stone 6 during cutting, thus providing precise feedback signals for the dynamic speed control of the cylinder and ensuring that the cutting mechanism 1 maintains a stable feed speed under different working conditions. Furthermore, the equidistantly distributed universal balls ensure uniform force distribution at all points on the bottom surface of the stone 6.

[0038] In some embodiments, please refer to the appendix Figure 4 The limiting mechanism 3 includes a guide rail 31 and a limiting component 32 disposed opposite to it. The limiting component 32 is slidably connected to the guide rail 31. The limiting component 32 is disposed on both sides of the cutting mechanism 1, and the guide rail 31 is disposed across the top of the placement area 23.

[0039] The guide rail 31 refers to a linear guide structure spanning the upper part of the placement area 23, which can be implemented using I-beam rails or T-slot aluminum profiles. It is used to support the limiting component 32 and guide its lateral movement along the cutting area. The sliding connection refers to the movable assembly between the limiting component 32 and the guide rail 31 via a pulley system or slider 321. Specifically, it can be implemented using a structure that combines a linear bearing and an optical axis, allowing the limiting component 32 to slide freely along the length of the guide rail 31. The opposing limiting components 32 refer to two clamping units symmetrically distributed on both sides of the cutting mechanism 1. Adjusting the distance between them creates an adjustable clamping space.

[0040] Specifically, the guide rail 31 is mounted above both sides of the cutting mechanism 1 along the length of the placement area 23. The limiting components 32 move laterally by embedding the bottom slider 321 into the guide rail 31. When processing stones 6 of different widths, the operator can simultaneously move the limiting components 32 on both sides to a predetermined position along the guide rail 31, so that the distance between the inner working surfaces of the two limiting components 32 is equal to the width of the stone 6. When the stone 6 enters the cutting area under the action of the pushing mechanism 2, the working surfaces of the limiting components 32 on both sides remain in contact with the sides of the stone 6, forming a stable lateral constraint. The span position of the guide rail 31 is determined by calculation to ensure that the movement range of the limiting components 32 covers all conventional stone 6 sizes, while avoiding interference with the vertical movement trajectory of the cutting mechanism 1.

[0041] The combination design of guide rail 31 and sliding limit component 32 enables operators to quickly adjust the limit distance without stopping the machine, realizing real-time adjustment of the limit distance during the stone cutting process. This maintains the continuous operation capability of the equipment and avoids the time loss caused by frequent tooling changes.

[0042] In some embodiments, the limiting component 32 includes a slider 321, a second cylinder 322 and a limiting member 323. The slider 321 and the guide rail 31 are slidably connected. The mounting end of the second cylinder 322 is connected to the slider 321, and the driving end of the second cylinder 322 is connected to the limiting member 323. The limiting member 323 is provided with a limiting groove 324 corresponding to the stone 6.

[0043] Among them, slider 321 refers to the moving carrier that forms a sliding pair with guide rail 31. Specifically, it can be implemented by using a linear slider 321 with a ball retainer. Its internal balls contact the guide rail 31 to achieve low-friction movement, and the sliding connection provides the limiting component 32 with the degree of freedom for lateral position adjustment.

[0044] Specifically, the sliding trajectory of slider 321 along guide rail 31 is perpendicular to the feeding direction of stone 6. When the size of stone 6 changes, second cylinder 322 drives limiting member 323 to move to the target position, so that limiting groove 324 fixes stone 6. During the cutting process, the two constraint surfaces of limiting groove 324 contact the two sides of stone 6 respectively, forming a bidirectional limiting effect. Second cylinder 322 controls the clamping force of limiting member 323 by adjusting air pressure, ensuring that stone 6 is fixed while avoiding excessive pressure that could cause surface damage. The fitting accuracy between slider 321 and guide rail 31 ensures the straightness of the moving trajectory of limiting member 323, keeping the clamping position error within the allowable range.

[0045] The position of the limiting component 32 can be infinitely adjusted by the sliding cooperation between the guide rail 31 and the slider 321, which can meet the compatibility requirements of various sizes of stone 6. In addition, the limiting component 323 can be controlled by the second cylinder 322 to adapt to different thicknesses of stone 6. Furthermore, the position of the limiting groove 324 and the clamping force can be dynamically adjusted to effectively suppress the deviation of stone 6 caused by cutting vibration, ensure the straightness of the cutting trajectory and the flatness of the surface, reduce the risk of edge cracking of stone 6 caused by excessive clamping, and extend the service life of the cutting equipment.

[0046] In some embodiments, the inner side of the limiting groove 324 is provided with a first plane 3241 and a second plane 3242 that are perpendicularly arranged, and the first plane 3241 is used to abut against the side of the stone 6.

[0047] Specifically, when the stone 6 is conveyed to the cutting area by the pushing mechanism 2, its side surface is completely in contact with the first plane 3241, forming a surface contact constraint. During the cutting process, the lateral offset force on the stone 6 is evenly transmitted to the limiting mechanism 3 by the first plane 3241, ensuring the stability of the stone 6's movement during the cutting process. The second plane 3242 forms an orthogonal geometric relationship with the first plane 3241, together constituting a three-dimensional positioning reference, ensuring that the stone 6 always maintains a perpendicular posture to the cutting mechanism 1 during the cutting process, effectively ensuring cutting accuracy.

[0048] Through the above technical solution, this application effectively suppresses the lateral displacement and deflection vibration of the stone 6 during the cutting process, and the establishment of the right-angle positioning benchmark makes the cutting verticality error small, significantly reducing the workload of subsequent finishing processes.

[0049] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 5 The limiting component 32 in this embodiment also includes a buffer layer 325, which is connected to the first plane 3241.

[0050] The buffer layer 325 refers to a flexible material layer set inside the limiting groove 324. Specifically, it can be made of rubber, polyurethane or silicone. It is fixed to the surface of the first plane 3241 by bonding or snapping, and is used to absorb the impact energy generated when the stone 6 comes into contact with the limiting component 32.

[0051] Specifically, when the stone 6 is pushed into the limiting groove 324, its side first contacts the surface of the buffer layer 325. The lateral vibration generated during cutting is transmitted through the stone 6 to the buffer layer 325, which dissipates the instantaneous impact force into heat energy through its own elastic deformation. The thickness of the buffer layer 325 can be set to 2-5 mm, absorbing vibration energy through material compression deformation while maintaining the positioning constraint of the stone 6. The buffer layer 325 is fixed to the first plane 3241 with double-sided tape to ensure no displacement during long-term use. When the stone 6 has dimensional tolerances, the buffer layer 325 can undergo elastic deformation of 0.1-0.3 mm, ensuring clamping stability while avoiding excessive compression of the stone 6.

[0052] By adding a buffer layer 325, an elastic buffer interface is formed at the contact surface between the stone 6 and the limiting component 32, achieving flexible contact between the side of the stone 6 and the limiting component 32, thus avoiding chipping and surface scratches on the stone 6 caused by hard impacts. Furthermore, the vibration energy generated during cutting is effectively absorbed by the buffer layer 325, reducing the impact of vibration on the positioning accuracy of the stone 6. The elastic properties of the buffer layer 325 can adapt to the clamping requirements of stones 6 of different thicknesses, extending the service life of the limiting component 32 while ensuring positioning accuracy.

[0053] In some embodiments, the limiting member 32 further includes an elastic member 326 and a pressing block 327. The elastic member 326 is connected between the pressing block 327 and the second plane 3242. The side of the pressing block 327 opposite to the stone 6 forms a third plane, which is used to abut against the upper surface of the stone 6.

[0054] Among them, the elastic element 326 refers to the connecting element with elastic deformation capability, which can be implemented by using a helical spring or a rubber block. It absorbs the cutting vibration energy and compensates for the thickness error of the stone 6 through elastic deformation.

[0055] Specifically, when the stone 6 is pushed into the limiting groove 324, the third plane of the pressure block 327 contacts the upper surface of the stone 6, and the elastic element 326 generates a preload in the vertical direction. When the vibration generated during the cutting process is transmitted to the pressure block 327 through the stone 6, the elastic element 326 undergoes compression or tension deformation, absorbing vibration energy and reducing rigid impact. When there are differences in the thickness of the stone 6, the expansion and contraction of the elastic element 326 is automatically adjusted to ensure that the third plane always remains in contact with the stone 6. The horizontal cutting reaction force is transmitted to the limiting component 32 through the second plane 3242, and the vertical jump is suppressed by the cooperation between the pressure block 327 and the elastic element 326. The local pressure generated at the unevenness of the stone 6 surface is dispersed by the surface contact of the third plane, avoiding stress concentration that could lead to damage to the stone 6.

[0056] The combination of elastic element 326 and pressure block 327 achieves flexible constraint in the vertical direction while maintaining horizontal limiting accuracy, effectively suppressing vertical runout and horizontal deviation of stone 6 during the cutting process and ensuring cutting precision. Furthermore, the dual action of elastic pre-tightening and planar contact maintains positioning stability while avoiding surface damage caused by hard contact, reducing the formation of indentations on the surface of stone 6.

[0057] In some embodiments, the limiting member 32 further includes a plurality of evenly spaced second universal balls 328, which are embedded in the third plane.

[0058] Specifically, when the stone 6 moves laterally under the action of the feeding mechanism 2, the upper surface of the stone 6 comes into contact with the third plane of the pressure block 327. The second universal ball 328 embedded in this plane converts the sliding friction between the traditional limiting component 32 and the stone 6 into rolling friction. During the cutting and advancing process, the friction between the pressure block 327 and the stone 6 can be reduced, avoiding the formation of a hard jam between the stone 6 and the pressure block 327, ensuring the smooth pushing of the stone 6, maintaining a stable feed speed, and ensuring smooth cutting.

[0059] Example 3: The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 6 The stone cutting device of this embodiment also includes a housing 4 and a cover 5. The housing 4 surrounds the cutting mechanism 1, the pushing mechanism 2 and the limiting mechanism 3. The cover 5 is hinged to the housing 4. The cover 5 is a transparent cover 5.

[0060] Specifically, the cover 5 can be a composite structure with an aluminum alloy frame inlaid with a transparent sheet, connected to the side wall of the housing 4 via hinges to form a flip-open structure, used to maintain a closed state during equipment operation and provide an operating passage during maintenance. The transparent cover 5 can be made of polycarbonate sheet with a thickness of 8-12mm, which enables visual monitoring of the cutting process through its high light transmittance, while maintaining the integrity of the protective structure.

[0061] Specifically, the housing 4 encloses the cutting mechanism 1, the feeding mechanism 2, and the limiting mechanism 3 within its internal space through a fully enclosed structure. Stone chips generated during cutting are confined within the housing 4 and discharged through the bottom chip collection port. High-frequency noise is attenuated by sound-absorbing cotton lined the inner wall of the housing 4. The cover 5 is hinged for 180-degree flip-opening and closing, allowing for maintenance without disassembling the entire structure; simply flipping the cover 5 exposes the internal components for inspection. The transparent cover 5 is made of impact-resistant polycarbonate material, which, while withstanding the impact of flying stone chips, allows operators to directly observe the contact state between the cutting blade and the stone 6, the feeding action of the feeding mechanism 2, and the clamping position of the limiting component 32, enabling real-time assessment of any deviation or jamming during the cutting process.

[0062] Through the above technical solution, this application effectively prevents the spread of cutting debris to the working environment, reduces the operating noise of the equipment to a safe threshold of less than 85 decibels, and allows the operator to check the contact status between the cutting blade and the stone 6 and the clamping position of the limiting mechanism 3 in real time through the transparent cover 5. During equipment maintenance, the tool can be replaced or the mechanism can be adjusted by flipping the cover 5, avoiding the tool wear and time waste caused by the traditional protective cover disassembly operation, and making the operation simple and convenient.
