Abstract
Description
Technical Field
[0001] This application relates to the field of diamond wire cutting, and more specifically, to a diamond wire cutting device and a stone cutting method. Background Technology
[0002] Currently, diamond wire cutting is commonly used for stone cutting. While diamond wire cutting is relatively mature in industries such as photovoltaics and semiconductor magnetic materials, multi-wire slicing machines are still in their infancy in the stone industry. Due to the large volume of raw stone blocks (up to 3.4*2.5*2.3m), the axial distance during cutting is significant, easily leading to large wire bowing. Furthermore, the stone slabs tend to stick together during cutting, and hard stone inclusions can easily form inside, resulting in even larger wire bowing. Excessive wire bowing can easily cause wire breakage, and repairing broken wires in stone often takes 5-8 hours!
[0003] Currently, the stone cutting process typically involves manual observation of the wire bow, with adjustments made manually when it becomes too large. This method is cumbersome, time-consuming, and prone to wire breakage if observation is not timely. Summary of the Invention
[0004] This application provides a diamond wire cutting device and a stone cutting method to solve the problem of wire breakage that easily occurs during stone cutting in the prior art.
[0005] In a first aspect, this application provides a diamond wire cutting device, comprising: a diamond wire, a conductive part, a power supply, and an output port. The conductive part is spaced at a preset distance from the diamond wire before it forms a bow. When the diamond wire forms a bow during the cutting process, the distance between the conductive part and the diamond wire decreases as the bow formed by the diamond wire increases, and the distance can be shortened to 0. A first pole of the power supply is connected to the conductive part, and a second pole of the power supply is connected to the diamond wire. The first pole is positive and the second pole is negative, or the first pole is negative and the second pole is positive. The output port is electrically connected to the conductive part or the diamond wire, and is used to output an electrical signal in the circuit formed by the power supply, the diamond wire, and the conductive part when the distance is shortened to 0.
[0006] In this embodiment, the diamond wire forms a bow during the cutting process. If the bow is large, the diamond wire will come into contact with the conductive part, thus forming a current loop with the power supply, the diamond wire, and the conductive part. An electrical signal is then output through the output port. Therefore, whether the bow of the diamond wire is too large can be detected by checking whether an electrical signal is output from the output port. This method eliminates the need for manual observation, preventing wire breakage due to delayed observation.
[0007] In conjunction with the technical solution provided in the first aspect above, in some possible embodiments, the diamond wire cutting device further includes: a relay, wherein the first coil terminal of the relay is connected to the first pole of the power supply, and the second coil terminal of the relay is connected to the second pole of the power supply through the conductive part and the diamond wire; the output port is connected to the conductive part through the normally open contact of the relay; or, the output port is connected to the diamond wire through the normally open contact of the relay.
[0008] In this embodiment, after the first coil terminal and the second coil terminal of the relay are turned on, the normally open contact of the relay will output an electrical signal. Since the normally open contact is connected to the output port, the effect of outputting an electrical signal through the output port is achieved when a current loop is formed.
[0009] In conjunction with the technical solution provided in the first aspect above, in some possible embodiments, the diamond wire cutting equipment further includes a first main roller and a second main roller; the diamond wire is wound around the first main roller and the second main roller; the conductive part includes a first conductive part and a second conductive part; the preset distance includes a first preset distance and a second preset distance; the first conductive part is disposed on a first side of the diamond wire and is spaced apart from the diamond wire without forming a bow by the first preset distance; the first side is one side of the diamond wire wound around the first main roller; the second conductive part is disposed on a second side of the diamond wire and is spaced apart from the diamond wire without forming a bow by the second preset distance; the second side is one side of the diamond wire wound around the second main roller; the output port is specifically used for: when the distance between the first conductive part and the diamond wire is shortened to 0, outputting an electrical signal in the circuit formed by the power supply, the diamond wire and the first conductive part; when the distance between the second conductive part and the diamond wire is shortened to 0, outputting an electrical signal in the circuit formed by the power supply, the diamond wire and the second conductive part.
[0010] In this embodiment, a first conductive part and a second conductive part are provided, with the first conductive part disposed on a first side of the diamond wire and the second conductive part disposed on a second side of the diamond wire. Therefore, during the stone cutting process, even if the highest point of the diamond wire bow is close to either the first or second side of the diamond wire, it can be more easily detected by the conductive part on the same side, improving the detection accuracy of this solution.
[0011] In conjunction with the technical solution provided in the first aspect above, in some possible implementations, the output port includes a first output port and a second output port; the first output port is electrically connected to the first conductive part, and the second output port is electrically connected to the second conductive part.
[0012] In this embodiment, two output ports are connected to the first conductive part and the second conductive part respectively, so that it can be more clearly determined which conductive part is in contact with the diamond wire.
[0013] In conjunction with the technical solution provided in the first aspect above, in some possible implementations, the conductive part is a long rod made of conductive material.
[0014] In conjunction with the technical solution provided in the first aspect above, in some possible embodiments, the diamond wire cutting device further includes: a displacement part, the displacement part being connected to both ends of the conductive part, the displacement part being used to change the position of the conductive part in the diamond wire cutting device.
[0015] In this embodiment, the position of the conductive part in the diamond wire cutting equipment is changed by the displacement part, thereby changing the preset distance setting between the conductive part and the diamond wire that has not formed a bow. This allows for adaptive adjustment according to actual needs, thereby improving the applicability of this solution.
[0016] In conjunction with the technical solution provided in the first aspect above, in some possible implementations, the displacement part includes: a first adjusting track, a second adjusting track, a first fixing block, and a second fixing block; wherein the first fixing block and the second fixing block are made of insulating material; the first fixing block is movably disposed on the first adjusting track, and the second fixing block is movably disposed on the second adjusting track; the first fixing block is connected to one end of the conductive part, and the second fixing block is connected to the other end of the conductive part.
[0017] Secondly, this application provides a stone cutting method, applied to the diamond wire cutting equipment described in the first aspect above and / or in combination with any possible implementation of the first aspect above. The method includes: during the process of cutting stone according to a preset first cutting method, detecting whether an electrical signal is output from the output port; when an electrical signal is detected from the output port, cutting the stone according to a preset second cutting method, and detecting whether the output port continuously outputs an electrical signal; wherein the feed speed in the second cutting method is less than the feed speed in the first cutting method; when no electrical signal is detected from the output port, cutting the stone according to the first cutting method, and detecting whether an electrical signal is output from the output port.
[0018] In this embodiment, if an electrical signal is detected at the output port, it indicates that the bow of the diamond wire is too large. If the first cutting method is still used, it may lead to wire breakage. Therefore, the cutting method is switched to a second cutting method with a feed rate lower than that in the first cutting method to reduce the possibility of wire breakage.
[0019] In conjunction with the technical solution provided in the second aspect above, in some possible implementations, the feed rate in the second cutting method is 0.
[0020] In this embodiment, when the bow of the diamond wire is too large, the feed rate is set to 0. At this point, the main target of cutting is the stone's inclusions or other factors causing the excessive bow. Since the cutting efficiency for these factors is low, if the feed rate remains greater than 0, the bow may continue to increase, potentially leading to wire breakage. Therefore, adjusting the feed rate to 0 until no electrical signal is output from the output port before resuming the first cutting mode reduces the probability of wire breakage.
[0021] In conjunction with the technical solution provided in the second aspect above, in some possible implementations, the second cutting method includes multiple cutting cycles performed sequentially, wherein the linear velocity of the diamond wire in each cutting cycle increases sequentially.
[0022] In conjunction with the technical solution provided in the second aspect above, in some possible implementations, the linear velocity of the diamond wire in the last cutting cycle of the second cutting method is equal to the linear velocity of the diamond wire in the first cutting method.
[0023] In this embodiment of the application, by setting the maximum diamond wire speed in the second cutting method to be equal to the diamond wire speed in the first cutting method, the probability of wire breakage due to excessive diamond wire speed can be reduced.
[0024] In conjunction with the technical solution provided in the second aspect above, in some possible implementations, if the last cycle of the second cutting method is completed, the output port still outputs an electrical signal, stops cutting the stone, and issues an alarm.
[0025] In this embodiment, after the last cycle of the second cutting method is completed, the output port still outputs an electrical signal, indicating that the bow wire is still too large and the second cutting method cannot solve this problem. Therefore, the stone cutting is stopped to prevent wire breakage. An alarm is issued to allow for manual intervention by the staff.
[0026] In conjunction with the technical solution provided in the second aspect above, in some possible implementations, the second cutting method includes: adjusting the feed speed to 0 and cutting at the same diamond wire linear speed as the first cutting method until a first preset time is reached or the output port is detected to have no output electrical signal; if the cutting time reaches the first preset time and the output port is still outputting an electrical signal, then the following operation is performed: cutting at the diamond wire adjustable linear speed until a second preset time is reached or the output port is detected to have no output electrical signal; if the cutting time reaches the second preset time and the output port is still outputting an electrical signal, then the diamond wire adjustable linear speed is increased; repeating the above operation until the output port is detected to have no output electrical signal, or until the diamond wire adjustable linear speed reaches a preset maximum diamond wire linear speed and the output port is still outputting an electrical signal; wherein: when the diamond wire adjustable linear speed reaches the preset maximum linear speed and the output port is still outputting an electrical signal, the cutting process is stopped and an alarm is issued.

[0043] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.
[0044] Please see Figure 1 , Figure 1 This is a structural block diagram of a diamond wire cutting device shown in an embodiment of this application.
[0045] The diamond wire cutting device includes a diamond wire 110, a conductive part 120, a power supply 130, and an output port 140.
[0046] Among them, the diamond wire 110 can be any type of conductive diamond wire 110.
[0047] The conductive part 120 is spaced at a predetermined distance from the diamond wire 110 before it forms a bow. As the diamond wire 110 forms a bow during the cutting process, the distance between the conductive part 120 and the diamond wire 110 decreases as the bow increases, and the distance can be reduced to zero. The first terminal of the power supply 130 is connected to the conductive part 120, and the second terminal of the power supply 130 is connected to the diamond wire 110. The output port 140 is electrically connected to either the conductive part 120 or the diamond wire 110, and is used to output an electrical signal from the circuit formed by the power supply 130, the diamond wire 110, and the conductive part 120 when the distance is reduced to zero.
[0048] During the cutting process, the diamond wire 110 forms a bow. If the bow is large, the diamond wire 110 will come into contact with the conductive part 120, thus forming a current loop with the power supply 130, the diamond wire 110, and the conductive part 120. This current loop then outputs an electrical signal through the output port 140. Therefore, by detecting whether the output port 140 outputs an electrical signal, the extent of the bowing of the diamond wire 110 can be determined. This method eliminates the need for manual observation, preventing wire breakage due to delayed observation.
[0049] The preset distance between the conductive part 120 and the diamond wire 110 that has not formed a bow can be set according to actual needs. The preset distance can be different for different types of diamond wire cutting equipment.
[0050] The first terminal of power supply 130 is positive and the second terminal is negative, or the first terminal of power supply 130 is negative and the second terminal is positive.
[0051] The negative terminal of power supply 130 can be connected to the equipment grounding of the diamond wire cutting equipment.
[0052] The power supply 130 can be any model of power supply 130, such as a 24V power supply 130. There is no restriction on its specific model here.
[0053] Optionally, the conductive part 120 can be any object with conductive capabilities, such as a straight conductive wire. Alternatively, the conductive part 120 can also be a long rod made of conductive material.
[0054] Output port 140 can be a pin, terminal block, etc. By connecting to this output interface, an electrical signal can be received from the output interface when the interval distance is reduced to 0.
[0055] Diamond wire cutting equipment typically also includes a first main roller 150 and a second main roller 160, with diamond wire 110 wound around the first main roller 150 and the second main roller 160. For easier understanding, please refer to [link to documentation]. Figure 2 .
[0056] like Figure 2 As shown, the diamond wire 110 passes down the left side of the first main roller 150 and then passes under the second main roller 160 and passes to the right side of the second main roller 160.
[0057] Optionally, multiple main rollers may be provided above the first main roller 150 and the second main roller 160, for example, one or two main rollers of equal number.
[0058] To facilitate understanding of the specific method by which diamond wire 110 forms a bow, the bow formation process is illustrated using a diamond wire cutting machine comprising four main rollers as an example. (See also...) Figure 3 Before cutting, the diamond wire 110 is straight. During the cutting process, the middle of the diamond wire 110 will bulge, forming a bow. If the bow is too large, it may cause the diamond wire 110 to break.
[0059] Depend on Figure 3 It can be seen that the protrusion direction of the wire bow is from the stone towards the diamond wire 110. Therefore, in order to achieve the formation of the wire bow by the diamond wire 110 during the cutting process, the distance between the conductive part 120 and the diamond wire 110 should decrease as the wire bow formed by the diamond wire 110 increases, and the distance can be reduced to 0. Thus, the conductive part 120 needs to be located on the side of the diamond wire 110 closest to the main roller, that is, within the area surrounded by the diamond wire 110.
[0060] Furthermore, since the diamond wire 110 is usually passed through the middle of the first main roller 150 and the second main roller 160 during the cutting process, the conductive part 120 needs to be set close to the first main roller 150 or the second main roller 160.
[0061] However, since the location of factors such as the stone core inside the stone that cause excessive bowing is uncertain, if the position of this factor in the stone is too far to the left or right (causing the highest point of the bow to be too far to the left or right), it may result in different angles of the diamond wire 110 on both sides of the stone.
[0062] For easier understanding, please refer to Figure 4 . Figure 4The left side shows the case where the highest point of the bow is slightly to the left. In this case, the angle (α1) on the left side of the bow is significantly greater than the angle (β1) on the right side of the bow, making the angle change on the right side of the bow less significant.
[0063] Figure 4 The right side shows the case where the highest point of the bow is slightly to the right. In this case, the angle (β2) on the right side of the bow is significantly greater than the angle (α2) on the left side, making the angle change on the left side of the bow less noticeable.
[0064] Since the angle change of the diamond wire 110 on one side is not significant in both cases, to improve the detection accuracy of this solution, the conductive part 120 can be configured to include a first conductive part 121 and a second conductive part 122. Correspondingly, the preset distance includes a first preset distance and a second preset distance, such as... Figure 5 As shown.
[0065] The first conductive portion 121 is disposed on the first side of the diamond wire 110 and is spaced apart from the diamond wire 110 without forming a wire bow by a first predetermined distance. Figure 5 As shown in h1); the first side is a diamond wire 110 wound around one side of the first main roller 150.
[0066] The second conductive part 122 is disposed on the second side of the diamond wire 110 and is spaced at a second predetermined distance from the diamond wire 110 where no bow is formed. Figure 5 (h2 shown); the second side is a diamond wire 110 wound around one side of the second main roller 160.
[0067] Accordingly, the output port 140 is specifically used to: output an electrical signal in the circuit formed by the power supply 130, the diamond wire 110 and the first conductive part 121 when the distance between the first conductive part 121 and the diamond wire 110 is shortened to 0; and output an electrical signal in the circuit formed by the power supply 130, the diamond wire 110 and the second conductive part 122 when the distance between the second conductive part 122 and the diamond wire 110 is shortened to 0.
[0068] Specifically, when the distance between the first conductive part 121 and the diamond wire 110 is shortened to 0, and the distance between the second conductive part 122 and the diamond wire 110 is shortened to 0, the output port 140 outputs an electrical signal superimposed on the circuit formed by the power supply 130, the diamond wire 110 and the first conductive part 121, and the circuit formed by the power supply 130, the diamond wire 110 and the second conductive part 122.
[0069] By providing a first conductive part 121 and a second conductive part 122, with the first conductive part 121 located on the first side of the diamond wire 110 and the second conductive part 122 located on the second side of the diamond wire 110, the detection accuracy of this solution is improved. This is achieved by providing a first conductive part 121 and a second conductive part 122, where the first conductive part 121 is located on the first side of the diamond wire 110 and the second conductive part 122 is located on the second side of the diamond wire 110 during stone cutting.
[0070] Optionally, the first preset distance and the second preset distance can be different or the same. The specific values of the first preset distance and the second preset distance can be set according to actual needs, and there are no restrictions on their specific values here.
[0071] Optionally, if the conductive part 120 includes a first conductive part 121 and a second conductive part 122, the output port 140 also includes a first output port 140 and a second output port 140.
[0072] The first output port 140 is electrically connected to the first conductive part 121, and the second output port 140 is electrically connected to the second conductive part 122. By connecting the two output ports 140 to the first conductive part 121 and the second conductive part 122 respectively, it is possible to more clearly determine which conductive part 120 is in contact with the diamond wire 110.
[0073] In one embodiment, the diamond wire cutting device further includes a relay. The first coil terminal of the relay is connected to the first pole of the power supply 130, and the second coil terminal of the relay is connected to the second pole of the power supply 130 via a conductive part 120 and the diamond wire 110.
[0074] Output port 140 is connected to conductive part 120 via normally open contact of relay; or, output port 140 is connected to diamond wire 110 via normally open contact of relay. That is, normally open contact of relay is connected to output port 140.
[0075] Since relays typically have five terminals, namely positive coil terminal, negative coil terminal, normally open contact, normally closed contact, and common contact, the positive coil terminal needs to be connected to the positive terminal of power supply 130, and the negative coil terminal needs to be connected to the negative terminal of power supply 130.
[0076] When the positive coil terminal needs to be connected to the positive terminal of power supply 130, and the negative coil terminal needs to be connected to the negative terminal of power supply 130, the normally open contact is turned on.
[0077] Therefore, when the first pole of the power supply 130 is positive and the second pole is negative, the first coil terminal of the relay is the positive coil terminal and the second coil terminal of the relay is the negative coil terminal.
[0078] Similarly, when the first pole of power supply 130 is negative and the second pole is positive, the first coil terminal of the relay is the negative coil terminal and the second coil terminal of the relay is the positive coil terminal.
[0079] Optionally, when the output port 140 includes a first output port 140 and a second output port 140, the relay may also include a first relay and a second relay.
[0080] At this time, the first coil terminal of the first relay is connected to the first pole of the power supply 130, and the second pole of the first relay is connected to one end of the first conductive part 121. The normally open contact of the first relay is connected to the first output port 140.
[0081] The first coil terminal of the second relay is connected to the first pole of the power supply 130, and the second pole of the second relay is connected to one end of the first conductive part 121. The normally open contact of the second relay is connected to the second output port 140.
[0082] For ease of understanding, a relay can also include a circuit diagram of a first relay and a second relay, as shown below. Figure 6 As shown in the diagram. In this diagram, "+" represents the positive coil terminal, and "-" represents the negative coil terminal. "L" represents the live wire, and "N" represents the neutral wire.
[0083] like Figure 6 As shown, when there is current between the positive and negative coil terminals of the first relay, the normally open contact 1 closes (conducting state), thereby outputting an electrical signal at the first output port.
[0084] Similarly, when there is current between the positive and negative coil terminals of the second relay, the normally open contact 2 will close (conducting state), thereby outputting an electrical signal at the second output port.
[0085] In one embodiment, the diamond wire cutting device further includes a displacement part, which is connected to both ends of the conductive part 120. The displacement part is used to change the position of the conductive part 120 in the diamond wire cutting device.
[0086] By changing the position of the conductive part 120 in the diamond wire cutting equipment through the displacement part, the preset distance between the conductive part 120 and the diamond wire 110 that has not formed a bow can be changed, so that it can be adaptively adjusted according to actual needs, thereby improving the applicability of this solution.
[0087] Optional, such as Figure 7As shown, the displacement part may include: a first adjusting track 171, a second adjusting track 172, a first fixing block 173, and a second fixing block 174; wherein the first fixing block 173 and the second fixing block 174 are made of insulating material.
[0088] The first fixing block 173 is movably mounted on the first adjusting rail 171, and the second fixing block 174 is movably mounted on the second adjusting rail 172.
[0089] The first fixing block 173 is connected to one end of the conductive part 120, and the second fixing block 174 is connected to the other end of the conductive part 120.
[0090] Since the first fixing block 173 and the second fixing block 174 are made of insulating material, there will be no situation where the conductive part 120 comes into contact with other parts of the diamond wire cutting equipment through the fixing block to form a circuit. This results in the conductive part 120 not being in contact with the diamond wire 110, but the output port 140 outputting an electrical signal.
[0091] Since the first fixing block 173 is connected to one end of the conductive part 120 and the second fixing block 174 is connected to the other end of the conductive part 120, and the first fixing block 173 can move on the first adjusting track 171 and the second fixing block 174 can move on the second adjusting track 172, the conductive part 120 can be moved by moving the first fixing block 173 and the second fixing block 174.
[0092] Optionally, the first fixing block 173 and the second fixing block 174 can be components with clamping functions, such as U-shaped clamping blocks. A U-shaped insulating block can be embedded in the U-shaped clamping block, and the conductive part 120 is fixed in the U-shaped insulating block by a locking screw.
[0093] Optionally, the first adjusting track 171 is arranged on one side of the diamond wire cutting equipment, parallel to the line connecting the first main roller 150 and the second main roller 160, and the second adjusting track 172 is arranged on the other side of the diamond wire cutting equipment, parallel to the line connecting the first main roller 150 and the second main roller 160. Figure 8 As shown.
[0094] Optionally, the displacement unit may further include a first rotating arm 175 and a second rotating arm 176, such as... Figure 7 As shown, one end of the first rotating arm 175 is rotatably connected to the first fixed block 173, and the second end of the first rotating arm 175 is connected to one end of the conductive part 120. One end of the second rotating arm 176 is rotatably connected to the second fixed block 174, and the second end of the second rotating arm 176 is connected to the other end of the conductive part 120. This allows the conductive part 120 to rotate about the line connecting the first fixed block 173 and the second fixed block 174 as a rotation axis.
[0095] When the conductive part 120 is rotated, the preset distance between the conductive part 120 and the diamond wire 110 that has not formed a bow can be adjusted.
[0096] Optionally, when the conductive part 120 includes a first conductive part 121 and a second conductive part 122, the displacement part may include a first displacement part and a second displacement part.
[0097] The first displacement portion is connected to both ends of the first conductive portion 121, and the first displacement portion is used to change the position of the first conductive portion 121 in the diamond wire cutting equipment. The second displacement portion is connected to both ends of the second conductive portion 122, and the second displacement portion is used to change the position of the second conductive portion 122 in the diamond wire cutting equipment.
[0098] The first displacement part and the second displacement part are implemented in the same way as the aforementioned displacement part, and will not be described in detail here for the sake of brevity.
[0099] In one embodiment, the diamond wire cutting device further includes a processor for controlling the diamond wire cutting device to perform a stone cutting method.
[0100] Optionally, the processor is connected to the output port 140 and performs adaptive feed adjustment when an electrical signal is detected at the output port 140.
[0101] Specifically, by adjusting the feed servo drive and motor, spindle servo drive and motor, and spool servo drive and motor in the diamond wire cutting equipment, parameters such as the feed speed and the linear speed of the diamond wire can be adjusted to reduce wire bowing.
[0102] Optionally, the processor can perform the following stone cutting methods.
[0103] Please see Figure 9 Based on the same technical concept, this application also provides a stone cutting method, which is applied to the aforementioned diamond wire cutting equipment. The following will describe the method in conjunction with... Figure 9 The steps involved are explained.
[0104] S100: During the process of cutting stone according to the preset first cutting method, detect whether the output port outputs an electrical signal.
[0105] The first cutting method is the preset cutting method for the stone. The second cutting method is used to solve the problem of excessive bow length.
[0106] S200: When an electrical signal is detected at the output port, the stone is cut according to the preset second cutting method, and the output port is continuously outputting an electrical signal is detected.
[0107] In the second cutting method, the feed speed is lower than that in the first cutting method.
[0108] In one implementation, the feed rate in the second cutting mode is 0. When the bow of the diamond wire is too large, setting the feed rate to 0 primarily targets factors causing the excessive bow, such as the stone's inclusions. Since cutting these factors is less efficient, if the feed rate remains greater than 0, the bow may continue to increase, potentially leading to wire breakage. Therefore, adjusting the feed rate to 0 until no electrical signal is output from the output port before reverting to the first cutting mode reduces the probability of wire breakage.
[0109] Optionally, when the feed rate is set to 0, the diamond wire linear speed can also be adjusted to a preset diamond wire linear speed. The preset diamond wire linear speed can be set according to actual conditions; its specific value is not limited here.
[0110] In one embodiment, the second cutting method includes multiple cutting cycles performed sequentially, with the linear velocity of the diamond wire increasing sequentially in each cutting cycle.
[0111] The linear speed of the diamond wire in the first cutting cycle can be preset.
[0112] Optionally, the diamond wire linear speed for each cycle can be increased by a preset value, or by a preset percentage each time. The preset value and percentage can be set according to actual needs; their specific values are not limited here.
[0113] For example, if the second cutting method includes four cutting cycles, with the diamond wire linear velocity increasing by V0 each time, and the diamond wire linear velocity in the first cutting cycle is V1, then the diamond wire linear velocity in the second cutting cycle is V2, and V2 = V0 + V1. The diamond wire linear velocity in the third cutting cycle is V3, and V3 = V0 + V2. The diamond wire linear velocity in the fourth cutting cycle is V4, and V4 = V0 + V3.
[0114] Alternatively, the second cutting method includes four cutting cycles, with the diamond wire velocity increasing by 20% each time. The diamond wire velocity in the first cutting cycle is V1. Then, the diamond wire velocity in the second cutting cycle is V2, and V2 = V1 * (1 + 20%). The diamond wire velocity in the third cutting cycle is V3, and V3 = V2 * (1 + 20%). The diamond wire velocity in the fourth cutting cycle is V4, and V4 = V3 * (1 + 20%).
[0115] The examples provided are for illustrative purposes only and should not be construed as limiting the scope of this application.
[0116] Optionally, the diamond wire velocity in the last cutting cycle of the second cutting method is equal to the diamond wire velocity in the first cutting method. By setting the maximum diamond wire velocity in the second cutting method to be equal to the diamond wire velocity in the first cutting method, the probability of wire breakage due to excessive diamond wire velocity can be reduced.
[0117] Optionally, if the output port still outputs an electrical signal after the last cycle of the second cutting method is completed, the stone cutting will stop and an alarm will be issued. If the output port still outputs an electrical signal after the last cycle of the second cutting method is completed, it indicates that the bow wire is still too large and the second cutting method cannot resolve the situation. Therefore, the stone cutting will be stopped to prevent wire breakage. An alarm will be issued to allow for manual intervention by staff.
[0118] In one implementation, the second cutting method can also be as follows: Figure 10 As shown.
[0119] First, adjust the feed speed to 0 and cut at the same diamond wire linear speed as the first cutting method until the first preset time is reached or no electrical signal is detected at the output port.
[0120] If the cutting time reaches the first preset duration and the output port is still outputting an electrical signal, then the following operation is performed: cut with the diamond wire adjusting speed until the second preset duration is reached or the output port is no longer outputting an electrical signal; if the cutting time reaches the second preset duration and the output port is still outputting an electrical signal, then increase the diamond wire adjusting speed.
[0121] Repeat the above operation until no electrical signal is detected at the output port, or until the diamond wire adjustment speed reaches the preset maximum diamond wire speed, and the output port is still outputting an electrical signal.
[0122] Specifically: when the diamond wire adjustment reaches the preset maximum wire speed and the output port is still outputting an electrical signal, the cutting process stops and an alarm is issued.
[0123] The first preset duration and the second preset duration can be the same or different. The first preset duration and the second preset duration can be set according to actual needs, and there will be no restrictions on their specific values here.
[0124] Optionally, the method of increasing the diamond wire linear speed is the same as the method of sequentially increasing the diamond wire linear speed in each cutting cycle, as described above. For the sake of brevity, it will not be repeated here.
[0125] Optionally, the duration of each stage of each second cutting method can be recorded using a timer.
[0126] For example, when the feed rate is adjusted to 0, the timer is reset, and cutting is performed at the same diamond wire linear speed as in the first cutting method. The timer continues to count until the time recorded by the timer reaches the first preset time or no electrical signal is detected at the output port.
[0127] If the cutting time reaches the first preset duration and the output port is still outputting an electrical signal, then the following operations are performed: The timer is reset, and cutting is performed at the diamond wire adjustment speed until the timer records a second preset duration or no electrical signal is detected at the output port; if the cutting time reaches the second preset duration and the output port is still outputting an electrical signal, then the diamond wire adjustment speed is increased, and the timer is reset. This process is repeated until no electrical signal is detected at the output port, or until the diamond wire adjustment speed reaches the preset maximum diamond wire speed, and the output port is still outputting an electrical signal.
[0128] Optionally, the specific value of the preset maximum diamond wire linear velocity can be set according to actual needs, such as the diamond wire linear velocity in the first cutting method.
[0129] S300: If no electrical signal is detected at the output port, the stone is cut according to the first cutting method, and the output port is checked to see if an electrical signal is output.
[0130] Optionally, the stone can be cut immediately according to the first cutting method if no electrical signal is detected at the output port.
[0131] Alternatively, if the second cutting method includes multiple cutting cycles, the stone can be cut according to the first cutting method after the current cutting cycle is completed when no electrical signal is detected at the output port.
[0132] Optionally, if an electrical signal is detected again at the output port, S200 is executed again until the stone cutting is complete.
[0133] To facilitate understanding of the above stone cutting method, the specific steps of one implementation method of the stone cutting method will be illustrated below.
[0134] The position of the conductive part in the diamond wire cutting equipment is pre-adjusted, and then the stone is cut according to the preset first cutting method.
[0135] During the process of cutting the stone according to the preset first cutting method, it is detected whether the output port outputs an electrical signal. If no electrical signal is detected at the output port, the stone continues to be cut according to the first cutting method.
[0136] If an electrical signal is detected at the output port, the feed speed is adjusted to 0, and the cutting is performed at the same diamond wire linear speed as the first cutting method, until the first preset time is reached or no electrical signal is detected at the output port.
[0137] If the cutting time reaches the first preset duration and the output port is still outputting an electrical signal, the timer is reset, and the diamond wire speed is adjusted to 20% of the diamond wire speed in the first cutting mode to cut the stone. If no electrical signal is detected at the output port within the second preset duration, cutting is performed according to the first cutting mode.
[0138] If the cutting time reaches the second preset time and the output port is still outputting an electrical signal, the timer is reset, and the diamond wire speed is increased to 40% of the diamond wire speed in the first cutting method to cut the stone. If no electrical signal is detected at the output port within the second preset time, cutting is performed according to the first cutting method.
[0139] Repeat the above steps to increase the diamond wire speed until no electrical signal is detected at the output port, then proceed with the first cutting method. Alternatively, stop the cutting process and issue an alarm when the diamond wire speed reaches the preset maximum and the output port is still outputting an electrical signal.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
