Description

Technical Field

[0001] The present invention relates to the field of wire cutting technology, and in particular to an intelligent online adjustable stone wire saw cutting system and method. Background Art

[0002] Diamond wire cutting is one of the main technologies for stone cutting. Wire cutting has many advantages such as high yield rate, low energy consumption and high flatness after cutting.

[0003] Diamond wire for cutting stone refers to a wire with diamond particles electroplated on the surface of the cutting wire (usually a steel wire); during cutting, the diamond wire is retracted and released back and forth using a winding device, so that the diamond particles on the surface of the diamond wire can be used to efficiently cut the stone.

[0004] However, when using diamond wire to cut stone, it is easy to cause the diamond wire to break due to the wear of the diamond wire, the mismatch between the feed speed of the stone cutting feed and the cutting efficiency, and even cause the stone cutting to fail or be scrapped.

When the output shaft of the first motor rotates, the swing rod can be driven to drive the winding wheel to swing to adjust the tension of the cutting line; the control device is also used to obtain the real-time torque of the first motor to obtain the pulling force according to the real-time torque and the length of the swing rod; or,

[0028] The intelligent online adjustable stone wire saw cutting system also includes a tension measuring instrument, which is used to detect the tensile force.

The change in the angle after the cutting wire is lifted by the stone is also positively correlated with the feed speed during stone cutting (that is, the faster the feed speed, the larger the angle α, and the slower the feed speed, the larger the angle α). The smaller α is); at the same time, the wear amount of the cutting line when cutting the stone is positively correlated with the tension and friction force exerted on the cutting line; therefore, when the control device obtains the wear amount, the wear amount of the cutting line can be adjusted by adjusting at least one of the initial deformation elongation of the cutting line and the feeding speed of the stone, for example: reducing the initial deformation elongation of the cutting line or reducing the feeding speed of the stone to reduce the wear amount of the cutting line, improve the matching degree between the feeding rate and the cutting efficiency, thereby improving the problem of easy breakage of the cutting line, and reliably reducing the problem of stone scrapping caused by stone cutting failure.

[0037] Moreover, when the control device obtains the amount of wear, the initial deformation elongation of the cutting line is adjusted to adjust the amount of wear of the cutting line, which is also conducive to adapting to a better feed speed. For example, by reducing the initial deformation elongation of the cutting line, the amount of wear can meet the requirements, and there is no need to reduce the feed speed. A relatively fast feed speed is conducive to ensuring higher cutting efficiency.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0053] Please refer to Figure 1 The present embodiment provides an intelligent and online adjustable stone wire saw cutting system 010, which includes a cutting wire 400 (specifically a diamond wire), a winding device 100 and a feeding device (not shown); the cutting wire 400 is wound on the winding device 100, and the cutting wire 400 can be retracted and released by the winding device 100, so that the cutting wire 400 can be reciprocated; the feeding device is used to place the stone 300, and can deliver the stone 300 to the reciprocating cutting wire 400 for cutting.

[0054] Furthermore, the cutting system also includes a control device 200, and the winding device 100 and the feeding device are both electrically connected to the control device 200. The control device 200 is used to control the winding device 100 to drive the cutting line 400 to move back and forth, and is also used to control the feeding device to deliver the stone 300 to be cut by the cutting line 400.

[0055] Optionally, the winding device 100 includes two rollers (hereinafter referred to as first rollers 111) and two second rollers 112, the two first rollers 111 and the two second rollers 112 are distributed in a rectangular array, and the two second rollers 112 are distributed above the two first rollers 111 in a one-to-one correspondence; the two first rollers 111 and the two second rollers 112 are used together to set the cutting line 400, and the cutting line 400 segment between the two first rollers 111 is used to cut the stone 300. It should be understood that in other embodiments, the winding device 100 may include only two first rollers 111; or, in other embodiments, in addition to the two first rollers 111 and the two second rollers 112, at least one third roller may be included, which is not specifically limited here.

[0056] For further information, please refer to Figure 1 and Figure 2 The winding device 100 also includes four parallel driving components 130, and the four driving components 130 are connected to the two first rollers 111 and the two second rollers 112 in a one-to-one transmission manner to drive the first rollers 111 and the second rollers 112 to rotate forward and reverse, thereby driving the cutting line 400 to move back and forth, and the reciprocating movement of the cutting line 400 segment between the two first rollers 111 can be used to achieve cutting of the stone 300.

[0057] Optionally, the drive assembly 130 includes a servo driver 131 and a second motor 132 electrically connected to the servo driver 131, and the second motor 132 is transmission-connected to the corresponding first roller 111 or the second roller 112; wherein the servo drivers 131 of the four drive assemblies 130 are connected in parallel, and the servo drivers 131 are electrically connected to the control device 200, so that the control device 200 can be used to control the start and stop of the servo driver 131 drive motor.

[0058] Optionally, see Figure 1The winding device 100 also includes a first wire roller 121 and a second wire roller 122, both of which are used to wind the cutting wire 400; wherein the cutting wire 400 is a whole diamond wire, which can be unwound from one of the first wire roller 121 and the second wire roller 122, and after being wound multiple times around the two first rollers 111 and the two second rollers 112, the wire is output from the other of the first wire roller 121 and the second wire roller 122; the cutting process includes: unwinding from the first wire roller 121, winding up the wire by the second wire roller 122, completing a forward cutting, then unwinding from the second wire roller 122, and winding up from the first wire roller 121, completing a reverse cutting, and repeating this cycle; wherein, during the reverse cutting, part of the wire that has been cut forward remains on the second wire roller 122, so as to achieve the purpose of updating and replenishing the new wire.

[0059] Optionally, the intelligent online adjustable stone wire saw cutting system 010 also includes a spray device 170 arranged above the winding device 100, the spray device 170 includes a spray pipe 171 and a water valve 172 arranged on the spray pipe 171, the spray pipe 171 is distributed above the first roller 111 and the second roller 112, and is used to spray water downward to cool the cutting line 400 and take away the powder generated after cutting; the water valve 172 is used to control the opening and closing of the spray pipe 171, wherein when the water valve 172 closes the spray pipe 171, no water is sprayed out from the spray pipe 171, and when the water valve 172 opens the spray pipe 171, water will be sprayed out from the spray pipe 171.

[0060] Optionally, see Figure 1 and Figure 3 The winding device 100 also includes a tensioning assembly 160, which includes a first motor 161, a swing rod 162 and a winding wheel 163. The winding wheel 163 is used to sleeve the cutting line 400. The two ends of the swing rod 162 are respectively connected to the output shaft of the first motor 161 and the winding wheel 163. When the output shaft of the first motor 161 rotates, the swing rod 162 can be driven to drive the winding wheel 163 to swing so as to adjust the tension of the cutting line 400; wherein, the first motor 161 is electrically connected to the control device 200, and the control device 200 is used to control the output shaft of the first motor 161 to rotate or stop rotating, and the control device 200 can also be used to obtain the real-time torque output by the first motor 161.

[0061] Optionally, the feeding device is used to place the stone 300 and can drive the stone 300 to rise and fall, so that the stone 300 can be cut by the cutting line 400 during the process of driving the stone 300 to rise. The structure and working principle of the feeding device are similar to those of the related art and will not be described in detail here.

[0062] It should be noted here that when the feeding device drives the stone 300 to rise so as to cut the stone 300 using the cutting wire 400, the cutting wire 400 needs to be reciprocated on the stone 300 for multiple times so that the diamond particles on the surface of the cutting wire 400 can slide out cutting marks on the stone 300 to achieve the purpose of cutting the stone 300; when the stone 300 is fed (that is, when the feeding device drives the stone 300 to rise to abut against the cutting wire 400 segment between the two first rollers 111), different feeding speeds will cause the cutting wire 400 to be subjected to different tensioning forces. When the feeding speed is too fast, the cutting wire 400 will not have time to complete the cutting, and the stone 300 will abut against the cutting wire 400 segment between the two first rollers 111 to a greater extent, resulting in the cutting wire 400 segment being subjected to a greater tensioning force, and the cutting wire 400 will be deflected to a certain extent relative to when the stone 300 is not cut to form an angle α (such as Figure 4 As shown); wherein, the faster the feeding speed, the greater the tension force provided by the stone 300 on the cutting line 400 segment between the two first rollers 111, and the larger the angle α; the slower the feeding speed, the smaller the tension force provided by the stone 300 on the cutting line 400 segment between the two first rollers 111, and the smaller the angle α.

[0063] Optionally, see Figure 1 The intelligent online adjustable stone wire saw cutting system 010 also includes a first detection device 140, which is used to detect the height b of the cutting line 400 lifted by the stone 300 when cutting the stone 300; wherein the height b is the vertical distance from the connection point between the cutting line 400 and the stone 300 on the side facing the first roller 111 to the initial position when the cutting line 400 is not cutting the stone 300.

[0064] Furthermore, the first detection device 140 may be a detection camera, which is electrically connected to the control device 200. The detection camera may obtain the height of the cutting line 400 before and after the cutting line 400 cuts the stone 300, and send the obtained height information of the cutting line 400 to the control device 200. The control device 200 obtains the height b (e.g., the height of the cutting line 400 lifted by the stone 300) when the cutting line 400 cuts the stone 300 according to the height information change of the cutting line 400 before and after the cutting of the stone 300. Figure 4 As shown); wherein, when the cutting line 400 does not cut the stone 300, its height is recorded as 0. When the cutting line 400 cuts the stone 300, the absolute value of the difference between the height at which the cutting line 400 is lifted and 0 is the height b. When it is necessary to use the detection camera to obtain the height, the water valve 172 is in a closed state, and no water is sprayed out from the spray pipe 171 to avoid the adverse effects of water flow on shooting accuracy and clarity.

[0065] It should be noted that when the cutting line 400 cuts the stone 300, the cutting line 400 is lifted by the stone 300, and the angle of rotation relative to the cutting line 400 when it is not lifted by the stone 300 is α. The specific angle of the angle α can be calculated according to the height b. The height b is easier to obtain in the cutting system, so it is calculated by formula 3: tanα=b / L 1 , calculating the angle α is easier and more convenient than directly measuring the angle α; where L 1 The distance that the cutting line 400 is pulled out from one of the first rollers 111 and extends vertically to the stone 300 .

[0066] It should also be noted that the above formula 3 is stored in the control device 200. When the control device 200 obtains the height b, formula 3 can be called to obtain the angle α.

[0067] Optionally, the intelligent online adjustable stone wire saw cutting system 010 also includes a second detection device, which is used to detect the wear of the cutting wire 400; wherein the wear includes the change in the wire diameter of the cutting wire 400 and the change in the density of diamond particles on the surface of the cutting wire 400 within a cutting cycle.

[0068] It should be noted that the above-mentioned cutting cycle may refer to: the cutting line 400 segment between the two first rollers 111 moves back and forth once, that is, the cutting line 400 segment between the two first rollers 111 moves from one first roller 111 to the other first roller 111, and then moves in the opposite direction from the other first roller 111 to the previous first roller 111, performing two sliding cuts on the stone 300.

[0069] Of course, in other embodiments, one cutting cycle may mean that a cutting line 400 segment between two first rollers 111 moves from one first roller 111 to the other first roller 111 , and a sliding cut is performed on the stone 300 .

[0070] It should also be noted that in the process of reciprocating and reversing the cutting line 400 segment between the two first rollers 111, there will be a pause moment in the movement of the cutting line 400, that is, after the cutting line 400 segment between the two first rollers 111 moves from one first roller 111 to the other first roller 111, before starting to reverse the movement, there will be a pause moment in the movement of the cutting line 400, that is, the reversing of the reciprocating movement of the cutting line 400 is achieved by the second motor 132 driving the first roller 111 forward and reverse rotation, and there will be a short pause time at the moment when the second motor 132 drives the first roller 111 to reverse rotation.

[0071] For further information, please refer to Figure 1The second detection device includes an electronic dial indicator 151 and an electron microscope 152; the electron microscope 152 and the electronic dial indicator 151 are both electrically connected to the control device 200; the electron microscope 152 is used to obtain image information of the cutting line 400 on the second wire roller 122, and send the image information to the control device 200, and the control device 200 obtains the density of diamond particles on the surface of the cutting line 400 according to the image information; the electronic dial indicator 151 is used to detect the wire diameter information of the cutting line 400, and sends the wire diameter information of the cutting line 400 to the control device 200; the control device 200 that obtains the diamond particle density on the cutting line 400 and the wire diameter of the cutting line 400 can derive the wear amount of the cutting line 400.

[0072] Of course, in other embodiments, the electron microscope 152 may also be used to obtain image information of the cutting line 400 on any one of the first line roller 121 , the first roller 111 , and the second roller 112 .

[0073] For example, please refer to Figure 2 At the pause moment of a reversing cycle of the cutting wire 400 reciprocating, the control device 200 controls the electronic dial gauge 151 to clamp the cutting wire 400 to measure the diameter (wire diameter) of the cutting wire 400.

[0074] Exemplarily, the second detection device also includes a lifting component, which includes but is not limited to an electric push rod and a cylinder; the lifting component is connected to the electron microscope 152 in transmission, and is used to drive the electron microscope 152 to approach or move away from the cutting line 400 segment that needs to be photographed, for example: the lifting component is used to drive the electron microscope 152 to descend to the first line roller 121 to obtain clear image information of the cutting line 400 at a fixed focal length.

[0075] The inventors have found that the degree of wear can be divided into 0-100% according to empirical values ​​(for example, the wire diameter changes from an initial wire diameter of 0.55 mm to a limit wire diameter of 0.5 mm, which represents a wear degree of 0% to 100%, that is, the wire diameter change rate is 0% to 100%. Taking the wire diameter change of 0.0005 mm in a cutting cycle as an example, the wire diameter change rate corresponding to the cycle is (0.0005 / (0.55-0.5))×100%=1%; accordingly, the diamond particles on the surface of the cutting wire 400 can change according to the particle density, and the degree of wear can be divided into 0%-100% according to the change rate of the particle density), that is, the wear amount mentioned in the present disclosure can be defined by the wear rate of the cutting wire 400 (of course, in other embodiments, the wear amount can also be defined by the absolute value of the change in the wire diameter of the cutting wire 400 and the absolute value of the change in the diamond particles on its surface). Due to the large cutting range and the texture of stone 300 during the stone 300 wire cutting process, in order to ensure the cutting effect and uninterrupted wire, when the surface particle density decreases by 50% compared with the original, it is considered to be unusable. Therefore, the wear amount of diamond particles ρ per unit time (defined by the diamond particle density change rate) is 1 / 2 of the wire diameter wear amount (defined by the wire diameter change rate), that is, the wear rate of cutting wire 400 can be calculated as follows: wear rate = (wire diameter change rate + 2 × diamond particle density change rate) / 2; where the wire diameter change rate refers to the ratio of the wire diameter change amount of the cutting wire 400 between the current cycle and the previous cycle to the wire diameter limit wear amount; the diamond particle density change rate refers to the ratio of the wire diameter change amount of the cutting wire 400 between the current cycle and the previous cycle to the wire diameter limit wear amount; the diamond particle density change rate refers to the ratio of the wire diameter change amount of the cutting wire 400 between the current cycle and the previous cycle to the wire diameter limit wear amount. The ratio of the density change of diamond particles in the previous cycle to the limit change of the density of diamond particles; the limit wear of wire diameter is the difference between the initial wire diameter of the cutting wire 400 under the initial parameter conditions and the set limit wire diameter (for example: the wire diameter changes from the initial wire diameter 0.55mm to the limit wire diameter 0.5mm, and the limit wear of the wire diameter is 0.55mm-0.5mm=0.05mm). Similarly, the limit change of the density of diamond particles is the difference between the initial density of diamond particles on the cutting wire 400 under the initial parameter conditions and the set limit particle density. When the limit wire diameter and the limit particle density are reached, the cutting wire 400 cannot be cut and needs to be supplemented or replaced with a new wire.

[0076] Among them, the wire diameter change rate and the diamond particle density change rate are obtained by the control device 200 according to the wire diameter information of the cutting wire 400 and the diamond particle density information of the cutting wire 400 received by it. For example, the control device 200 can obtain the wire diameter change rate of the cutting wire 400 by comparing the wire diameter information of the cutting wire 400 received in the current cutting cycle and the previous cutting cycle. Similarly, the control device 200 can obtain the diamond particle density change rate of the cutting wire 400 by comparing the diamond particle feature images of the cutting wire 400 received in the current cutting cycle and the previous cutting cycle. The wire diameter change rate and the diamond particle density change rate are both taken as the absolute value of the change difference.

[0077] It should be noted that, when the current cutting cycle is the first cutting cycle, that is, when there is no other cutting cycle before the current cutting cycle, the control device 200 can obtain the wire diameter change rate by comparing the wire diameter information of the current cutting cycle with the original wire diameter information before the cutting line 400 cuts the stone 300. Similarly, the control device 200 can obtain the diamond particle density change rate by comparing the diamond particle characteristic image of the current cutting cycle with the original diamond particle characteristic image before the cutting line 400 cuts the stone 300.

[0078] For example, since the cutting wire 400 cuts the stone 300 by continuously reciprocating the retracting and releasing wire, the length setting of the retracting and releasing wire will directly affect the cutting effect and the consumption of consumables. The pay-off length is determined by the size of the rough material. For example, if the width of the rough material is 1.6 m and the thickness of the cutting plate is 20 mm, 80 cutting wires 400 can be wound around the first roller 111 and the second roller 112, and each circle of the wire net wound around the first roller 111 and the second roller 112 is 12.5 m long (i.e., the length of one circle of cutting wire 400 wound around the two first rollers 111 and the two second rollers 112 is 12.5 m), (1.6 / 0.020)×12.5=1000 m (i.e., the total length of 80 circles of cutting wire 400 wound around the two first rollers 111 and the two second rollers 112 is 1000 m), and the pay-off length is set to 1 times the wire net length, so the pay-off length is set to 1000 m. The take-up length can be set first with a difference of 20 m based on past experience. That is, first pay out 1000m of wire, and then take back 980m of wire. In each cycle, 20m of new wire will be used for cutting. This 20m of new wire will be used up after 50 cycles. That is, under the premise of keeping the rising speed of the working platform unchanged, the reasonable wear amount (rate) per cycle is 100% / 50=2%.

[0079] In the cutting system of the related art, when the voltage is unstable or the voltage is reduced, the servo driver 131 will alarm, and the control device 200 can control the servo driver 131 to drive the second motor 132 to stop. However, since the control device 200 cannot complete the shutdown control in time when the voltage is unstable or the voltage is reduced, it is difficult to stop multiple second motors 132 at the same time. Multiple second motors 132 that stop one after another are likely to pull the cutting line 400, which is likely to cause the cutting line 400 to break. To improve the above problems, please refer to Figure 2The intelligent online adjustable stone wire saw cutting system 010 of this embodiment also includes a capacitor 133, which is connected in parallel with the drive assembly 130; specifically, the control device 200 is connected to an uninterruptible power supply 210, and the capacitor 133 is connected in parallel with the servo driver 131 of the drive assembly 130; when the voltage of the power grid of the cutting system is unstable or the voltage is reduced, the capacitor 133 discharges in a short time (about 30 milliseconds) to maintain the short-term voltage of the power grid, and the control device 200 issues a shutdown command to control the second motor 132 driven by the servo driver 131 to stop synchronously, that is, to ensure that the control device 200 can reliably control the servo driver 131 to drive the second motor 132 to stop synchronously, effectively improving the problem of the cutting line 400 being pulled or even torn off; wherein, when the control device 200 issues a shutdown command, the capacitor 133 does not work, and the second motor 132 relies on its own power generation to maintain the shutdown when it stops.

[0080] Furthermore, during the shutdown of the drive assembly 130, the second motor 132 is in a power generation state (i.e., a charging state), in order to achieve the purpose of energy conservation and emission reduction; please refer to Figure 5 The intelligent online adjustable stone wire saw cutting system 010 of this embodiment further includes an energy feedback device 134, which is connected in parallel with the drive assembly 130. Specifically, the energy feedback device 134 is connected in parallel with the servo driver 131, and is used to feed back electric energy to the power grid to which the drive assembly 130 is connected when the drive assembly 130 (i.e., the second motor 132) generates electricity. The structure and working principle of the energy feedback device 134 are similar to those of the related art, and will not be described in detail here.

[0081] As mentioned above, when the cutting wire 400 with diamond particles on the surface is used to cut the stone 300, the cutting wire 400 will be worn. The degree of wear of the cutting wire 400 determines its service life and has a significant impact on the efficiency and effect of cutting.

[0082] In order to extend the service life of the cutting wire 400, improve the cutting efficiency, and ensure a good cutting effect; the control device 200 of this embodiment is configured to perform a tension acquisition step, a height acquisition step, and a wear acquisition step; the tension acquisition step includes acquiring the tension of the cutting wire 400, and obtaining the initial deformation elongation of the cutting wire 400 (i.e., the deformation elongation of the cutting wire 400 segment between the two first rollers 111 when the stone 300 is not cut) according to Formula 1 and the tension of the cutting wire 400. Formula 1 is F 1 = k(L 1 / cosα-L 1 +L 2 ), F 1 is the tension, L 1The distance that the cutting line 400 is pulled out from one of the first rollers 111 and vertically extends to the stone 300 (e.g. Figure 4 ), α is the rotation angle of the cutting line 400 after being lifted by the stone 300 relative to the rotation angle when the cutting line 400 is not lifted by the stone 300 (as shown in FIG. Figure 4 shown), L 2 is the initial deformation elongation, k is the elastic coefficient of the cutting line 400; the height acquisition step includes acquiring the height b of the cutting line 400 after being lifted by the stone 300, and obtaining the friction force when the cutting line 400 cuts the stone 300 according to formula 2 and the height b, and formula 2 is F 2 =2μF 1 sinα, F 2 is the friction force, μ is the friction coefficient of the cutting line 400; the wear amount acquisition step includes acquiring the wear amount of the cutting line 400, and adjusting the initial deformation elongation according to the wear amount, and / or adjusting the speed of the feeding device delivering the stone 300 to achieve the adjustment of the wear amount.

[0083] According to Formula 1, the initial deformation elongation of the cutting wire 400 stretched between the two first rollers 111 before cutting the stone 300 is positively correlated with the tension during the process of the cutting wire 400 cutting the stone 300; according to Formula 2, the friction force of the cutting wire 400 when cutting the stone 300 is positively correlated with the tension it receives and the change in the angle after the cutting wire 400 is lifted by the stone 300. The change in the angle after the cutting wire 400 is lifted by the stone 300 is also positively correlated with the feed speed during the cutting of the stone 300 (that is, the faster the feed speed, the larger the angle α, and the slower the feed speed, the smaller the angle α); at the same time, the cutting wire 400 The amount of wear when cutting the stone 300 is positively correlated with the tension and friction applied to the cutting line 400; therefore, when the control device 200 obtains the amount of wear, the wear of the cutting line 400 can be adjusted by adjusting at least one of the initial deformation elongation of the cutting line 400 and the feed speed of the stone 300. For example, the initial deformation elongation of the cutting line 400 can be reduced or the feed speed of the stone 300 can be reduced to reduce the wear of the cutting line 400 and improve the matching degree between the feed rate and the cutting efficiency, thereby improving the problem of easy breakage of the cutting line 400 and reliably reducing the problem of stone 300 being scrapped due to failure in cutting the stone 300.

[0084] Moreover, when the control device 200 obtains the amount of wear, the initial deformation elongation of the cutting line 400 is adjusted to adjust the amount of wear of the cutting line 400, which is also conducive to adapting to a better feed speed. For example, by reducing the initial deformation elongation of the cutting line 400, the amount of wear can meet the requirements, and there is no need to reduce the feed speed. A relatively fast feed speed is conducive to ensuring higher cutting efficiency.

[0085] Optionally, in some embodiments, when the control device 200 obtains the amount of wear, the control device 200 can compare the acquired amount of wear of the current cutting cycle with the reasonable wear amount (rate) of 2% for each cutting cycle as mentioned above, and when it is determined that the amount of wear of the current cutting cycle is greater than the reasonable wear amount, the control device 200 can control the tensioning assembly 160 to adjust the tensioning degree of the cutting line 400, thereby adjusting the initial deformation elongation of the cutting line 400, or control the feeding device to slow down the speed of cutting and feeding the stone 300.

[0086] In other embodiments, when the control device 200 obtains the amount of wear, the control device 200 can compare the acquired amount of wear of the current cutting cycle with the amount of wear of other cutting cycles before the current cutting cycle to select a cutting cycle with a more suitable amount of wear, and adjust the initial deformation elongation of the cutting line 400 and the feeding speed of the feeding device based on the initial deformation elongation of the cutting line 400 corresponding to the cutting cycle and the feeding speed of the feeding device until the initial deformation elongation and feeding speed of the cutting line 400 that meet the cutting rate requirements and wear requirements of the stone 300 are obtained, and subsequent cutting can be carried out according to the initial deformation elongation and feeding speed of the cutting line 400 that meet the requirements.

[0087] In order to enable the control device 200 to compare the wear amount of multiple cycles, the control device 200 is also configured to cyclically execute the tension acquisition step, the height acquisition step and the wear amount acquisition step at least twice until the wear amount meets the requirements while ensuring that the cutting efficiency meets the requirements.

[0088] Optionally, the control device 200 is further configured to cycle the tension acquisition step, the height acquisition step, and the wear acquisition step for more than 100 times. By cycling the tension acquisition step, the height acquisition step, and the wear acquisition step for multiple times, it is beneficial to obtain the initial deformation elongation parameter and the feed speed parameter of the cutting wire 400 with low wear and high cutting efficiency, so as to facilitate the subsequent cutting according to the above-mentioned more optimal parameters, improve the cutting efficiency, and improve the problem of easy wear and short life of the cutting wire.

[0089] Furthermore, the control device 200 is further configured to cycle the tension acquisition step, the height acquisition step, and the wear acquisition step for 700 times, or even more than 700 times. Cycling the tension acquisition step, the height acquisition step, and the wear acquisition step for more times can select and adapt to more suitable initial deformation elongation parameters and feed speed parameters of the cutting wire 400.

[0090] Optionally, the control device 200 is further configured to: in the period from the beginning of cutting to the end of cutting of the stone material, the tension acquisition step, the height acquisition step and the wear acquisition step are cyclically executed 150-250 times. In this way, more suitable initial deformation elongation parameters and feed speed parameters of the cutting wire 400 can be adapted, and efficiency can be improved.

[0091] When the stone 300 is delivered for wire cutting by the feeding device, the feeding device is configured to deliver the stone 300 along the height direction of the stone 300 to a position where it can be cut by the cutting wire 400. When cutting to different heights of the stone 300, the cutting wire 400 has different tolerances to wear. For example, in the initial period of cutting the stone 300, the contact between the two sides of the stone 300 and the cutting wire 400 is relatively sharp, and the cutting wire 400 is more easily worn by the stone 300 in the initial period of cutting, that is, the cutting wire 400 has a lower tolerance to wear in the initial period of cutting the stone 300. As the cutting process of the stone 300 progresses, the two sides of the stone 300 are polished relatively smoother by the cutting wire 400 than in the initial cutting, and the stone 300 is smoother. The sharpness of the contact between the stone 300 and the cutting wire 400 is reduced, and the cutting wire 400 is not so easily worn compared to the initial period of cutting, that is, the tolerance of the cutting wire 400 to wear is increased; therefore, the control device 200 of this embodiment is also used to execute the tension acquisition step, the height acquisition step and the wear amount acquisition step at different cutting heights of the stone 300, so that when the cutting wire 400 cuts at different heights of the stone 300, the corresponding wear amounts meet the requirements, that is, the control device 200 executes the tension acquisition step, the height acquisition step and the wear amount acquisition step when cutting at different heights of the stone 300, to train and find the initial deformation elongation and feeding speed of the cutting wire 400 that meet the wear amount requirements.

[0092] Exemplarily, the stone 300 can be divided into multiple cutting sections in its height direction, such as divided into three cutting sections, namely, a one-third height cutting section, a two-thirds height cutting section and a three-thirds height cutting section from bottom to top. The cutting of the stone 300 is carried out from top to bottom, that is, the three-thirds height cutting section is cut first, and then the two-thirds height cutting section and the one-third height cutting section are cut in sequence. When cutting the three-thirds height cutting section, the two-thirds height cutting section and the one-third height cutting section respectively, the control device 200 can perform at least one tension acquisition step, height acquisition step and wear amount acquisition step to train and find the initial deformation elongation and feed speed of the cutting line 400 whose wear amount meets the requirements (for example: less than 2% wear amount (rate)).

[0093] It should be noted that the number of cutting sections into which the stone 300 is divided in the height direction can be selected as needed, for example: one section, two sections, three sections, four sections, etc., which is not specifically limited here.

[0094] It should be understood that the control device 200 executing the tension acquisition step, the height acquisition step and the wear acquisition step can be regarded as training and modeling. For example, the intelligent online adjustable stone wire saw cutting system 010 usually needs to continuously cut multiple stones 300. When cutting the first stone 300, the control device 200 is used to execute at least one tension acquisition step, height acquisition step and wear acquisition step to determine the initial deformation elongation and feed speed of the cutting line 400 corresponding to the cutting cycle in which the wear amount meets the requirements. When cutting other subsequent stones 300, the cutting model parameters trained for cutting the first stone 300 (i.e., the initial deformation elongation and feed speed of the cutting line 400) can be directly used for cutting to ensure cutting efficiency.

[0095] Optionally, the tension of the cutting line 400 before and after cutting the stone 300 does not exceed the maximum bearing capacity of the cutting line 400; the maximum bearing capacity of the cutting line 400 refers to the minimum tension at which the cutting line 400 is torn apart by an external force. When the tension of the cutting line 400 does not exceed its maximum bearing capacity, it can ensure that the cutting line 400 does not break when cutting the stone 300.

[0096] Furthermore, when the cutting wire 400 has not yet cut the stone 300, the tension of the cutting wire 400 is adjusted by the tensioning assembly 160 so that the tension applied to the cutting wire 400 is 50%-60% of its maximum bearing capacity. In this way, when the cutting wire 400 starts to cut the stone 300, the tension applied to the cutting wire 400 is too large, which increases the wear of the cutting wire 400 and even causes the cutting wire 400 to break.

[0097] The tension of the cutting line 400 can be obtained in the following manner: the control device 200 obtains the real-time torque of the first motor 161, and obtains the tension according to the obtained real-time torque and the length of the rocker 162; specifically, it can be obtained by Formula 4: F tension = real-time torque of the first motor 161 (T) / length of the rocker 162 (L) / 2.

[0098] Of course, in other embodiments, the intelligent online adjustable stone wire saw cutting system 010 also includes a tension meter, which is used to detect tension; the above-mentioned tension meter may refer to a handheld digital tension meter (i.e., a tension tester), which is used to manually measure the tension (tension) of the cutting wire 400.

[0099] Optionally, the friction force does not exceed the maximum friction force of the cutting wire 400; the maximum friction force of the cutting wire 400 refers to the minimum friction force at which the cutting wire 400 is broken by friction. When the cutting wire 400 cuts the stone 300, the friction force does not exceed the maximum friction force of the cutting wire 400. On the one hand, it ensures that the wire is not broken when cutting the stone 300. On the other hand, it can improve the problem of diamond chipping on the surface of the cutting wire 400, and improve the problem that the cutting wire 400 cannot complete the cutting of the stone 300 due to chipping when the wear amount meets the requirements (for example, less than 2% of the reasonable wear amount (rate)).

[0100] Furthermore, when cutting the stone 300, the friction force of the cutting wire 400 is 50%-60% of its maximum friction force. In this way, the problem of the cutting wire 400 breaking can be reliably improved, and the wear of the cutting wire 400 can be reduced, while not causing the cutting efficiency of the stone 300 to be too low.

[0101] Furthermore, the cutting of the stone 300 is divided into an initial cutting stage and a subsequent cutting stage; wherein the friction force in the initial cutting stage is 10%-30% of the maximum friction force of the cutting wire 400, and the friction force in the subsequent cutting stage is 40%-60% of the maximum friction force of the cutting wire 400. As mentioned above, when the stone 300 starts to be cut, the tolerance of the cutting wire 400 is relatively low (for example, when cutting a three-thirds height cutting section of the stone 300, the tolerance of the cutting wire 400 is lower than that of cutting a two-thirds height cutting section of the stone 300). In the initial cutting stage, the friction force of the cutting wire 400 is smaller than that of the subsequent cutting, which is conducive to improving the problem of the cutting wire 400 being worn out too early or even broken. In the subsequent cutting, the friction is increased, which is conducive to improving the cutting efficiency of the stone 300.

[0102] Optionally, the control device 200 is also used to control the feeding device to reduce the speed of delivering the stone 300 when the wear amount obtained in the wear amount acquisition step is greater than the set wear amount (such as the aforementioned reasonable wear amount (rate) 2%), and make the speed of the feeding device delivering the stone 300 greater than the minimum allowable feeding speed; at the same time, the control device 200 is also used to reduce the initial deformation elongation when the speed of the feeding device delivering the stone 300 is less than or equal to the minimum allowable feeding speed and the wear amount is greater than the set wear. In this way, when the wear amount is large, the wear can be adjusted by reducing the feed rate first, and at the same time, it is necessary to ensure that the feed speed is greater than the minimum allowable feed speed to ensure the efficiency of cutting; however, if the feed speed has been reduced to less than or equal to the minimum allowable feed speed, and the wear amount is still greater than the set wear, it is necessary to adjust the wear amount by reducing the initial deformation elongation of the cutting line 400.

[0103] It should be noted that when the wear amount is adjusted by reducing the initial deformation elongation of the cutting line 400, the feed speed may be increased accordingly, and even made greater than the minimum allowable feed speed, to ensure reliable cutting efficiency.

[0104] It should also be noted that the above-mentioned minimum allowable feed speed refers to: the slowest stone 300 feed speed that can achieve effective cutting.

[0105] Please refer to Figure 6 This embodiment also provides a cutting method for the aforementioned intelligent online adjustable stone wire saw cutting system 010, which includes:

[0106] S100: obtaining the tension of the cutting line 400, and obtaining the initial deformation elongation of the cutting line 400 according to Formula 1 and the tension;

[0107] S200: Obtaining the height, and obtaining the friction force when the cutting line 400 cuts the stone 300 according to Formula 2 and the height b;

[0108] S300: Obtain the amount of wear, and adjust the initial deformation elongation according to the amount of wear, and / or adjust the speed at which the feeding device delivers the stone 300 to adjust the amount of wear.

[0109] The cutting method can effectively reduce the wear of the cutting wire 400, improve the matching degree between the feed rate and the cutting efficiency, thereby improving the problem of the cutting wire 400 being easily broken, and reliably reduce the problem of the stone 300 being scrapped due to the failure of the stone 300 cutting; and also includes ensuring good stone 300 cutting efficiency.

[0110] In summary, the cutting system and the corresponding cutting method of the present invention can reduce the wear of the cutting wire 400 and adapt to a better stone 300 cutting feed speed to improve the problem of easy breakage of the cutting wire 400 and reliably reduce the problem of stone 300 cutting failure resulting in the scrapping of the stone 300.

[0111] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
