[0002] With the development of industrial technology, processing methods different from the traditional ones are also developing rapidly, among which wire saw cutting technology is gradually widely applied.

[0003] A wire saw cutting machine achieves the purpose of cutting through the movement of the wire saw. Most wire saw cutting machines in the prior art achieve cutting through the cyclic winding of the wire saw. However, once the wire saw part of such a cutting machine wears out, the entire wire saw needs to be replaced, which is not only inconvenient to replace but also costly. In addition, there are some other wire saw cutting machines that achieve cutting through reciprocating motion and the like. However, such cutting machines often have complex operations and low automation levels and cannot be widely applied. In view of this, the inventor specifically proposed this application after studying the existing technologies. Summary of the Invention

[0008] As a further optimization, the control mechanism includes a first pressure regulating valve, a second pressure regulating valve, and a third pressure regulating valve respectively connected to the pressure supply source. The first pipeline and the second pipeline are connected to the first pressure regulating valve in parallel. The third pipeline and the fourth pipeline are connected to the second pressure regulating valve in parallel. The switching valve is connected to the pressure supply source in a way that connects to the third pressure regulating valve.

[0009] As a further optimization, the control mechanism includes a first on-off valve, a second on-off valve, a third on-off valve, and a fourth on-off valve. The first on-off valve is connected to the first pipeline, the second on-off valve is connected to the second pipeline, the third on-off valve is connected to the parallel pipeline of the third pipeline and the fourth pipeline, and the fourth on-off valve is connected to the input pipeline of the switching valve.

[0010] As a further optimization, the pressure supply source is an air supply source or a liquid supply source, and the first driving assembly and the second driving assembly are cylinder telescopic assemblies or liquid cylinder telescopic assemblies.

[0011] As a further optimization, the wire saw cutting machine includes a machine table, and the machine table is provided with a feeding mechanism for placing a workpiece. The wire paying-off assembly includes a wire paying-off wheel, and the wire taking-up assembly includes a wire taking-up wheel; the first driving assembly includes three first guide wheels arranged vertically, the second driving assembly includes three second guide wheels arranged vertically, and the wire saw winds around the three second guide wheels and the three first guide wheels in a counterclockwise, clockwise, and counterclockwise manner respectively.

[0012] The present application further provides a control method for a wire saw cutting machine. This control method is applicable to any of the above-mentioned wire saw cutting machines. The wire saw includes a first section located between the wire pay-off assembly and the second clamping assembly, a second section located between the second clamping assembly and the first clamping assembly, and a third section located between the first clamping assembly and the wire take-up assembly. The second section is used for cutting the workpiece. The specific control method of the wire saw cutting machine includes tensioning the wire saw, performing up-and-down cutting movement, and replacing the second section. The control method for tensioning the wire saw is as follows:

[0013] Control the output ends of the first driving assembly and the second driving assembly to extend outwards respectively;

[0014] Control the output end of the first driving assembly to retract, and control the output end of the second driving assembly to remain in the extended state;

[0015] Control the second clamping assembly to clamp the wire saw, and control the wire pay-off and take-up mechanism to tension the second section and the third section;

[0016] Control both the first clamping assembly and the second clamping assembly to clamp the wire saw, and control the wire pay-off and take-up mechanism to slacken the first section and the third section;

[0017] Control the output end of the first driving assembly to extend outwards, and control the output ends of the first driving assembly and the second driving assembly to remain in the extended state to tighten the second section.

[0018] As a further optimization, the control method for the up-and-down cutting movement is as follows:

[0019] Tension the wire saw;

[0020] Control the third pipeline and the fourth pipeline to be connected;

[0021] Control the switching valve to switch to the sixth pipeline to drive the output end of the first driving assembly to extend outwards, drive the output end of the second driving assembly to retract, and drive the second section to perform an upward cutting movement;

[0022] The switching valve switches to the fifth pipeline to drive the output end of the first driving assembly to retract, drive the output end of the second driving assembly to extend outwards, and drive the second section to perform a downward cutting movement.

[0023] As a further optimization, the control method for replacing the second section is as follows:

[0024] Control both the first clamping assembly and the second clamping assembly to release the wire saw;

[0025] Control the wire pay-off assembly to pay off wire and control the wire take-up assembly to take up wire, so that the second section moves towards the wire take-up assembly to switch the second section.

[0026] As a further optimization, controlling the first pipeline and the second pipeline to be connected can drive the first clamping assembly and the second clamping assembly to clamp the wire saw respectively; controlling the third pipeline and the fourth pipeline to be connected can drive the output ends of the first driving assembly and the second driving assembly to extend outwards respectively; controlling the fifth pipeline to be connected can drive the output end of the first driving assembly to retract; controlling the sixth pipeline to be connected can drive the output end of the second driving assembly to retract.

[0027] By adopting the above technical solutions, the present invention can achieve the following technical effects:

[0028] The wire saw cutting machine of the present invention not only has a simple structure, but also can realize the up and down reciprocating movement of the wire saw to achieve the purpose of cutting workpieces, improve the durability of the wire saw, and can also facilitate the part of the wire saw used for cutting. Specifically, for the wire saw cutting machine in this case, the wire saw comes out from the wire pay-off assembly, bypasses the second guide wheel and the first guide wheel in sequence, and is finally connected to the wire take-up assembly. Before cutting, it is necessary to tighten the wire saw. It is necessary to connect the first pipeline and the second pipeline at the same time to make the first clamping assembly and the second clamping assembly clamp the wire saw respectively. The wire saw is divided into a first section between the wire pay-off assembly and the second clamping assembly, a second section between the second clamping assembly and the first clamping assembly, and a third section between the first clamping assembly and the wire take-up assembly. The second section can move up and down to cut workpieces. The principle of the up and down movement of the second section is as follows:

[0029] First, control the third pipeline and the fourth pipeline to be connected, so that the output ends of the first driving assembly and the second driving assembly are both in the state of extending outwards. At this time, limited by the tightened second section, the output end of the first driving assembly does not move outwards to the limit.

[0030] Then, keep the third pipeline and the fourth pipeline in a connected state, and at the same time control the sixth pipeline to be connected through a switching valve. At this time, the fifth pipeline is disconnected. Since the pressure of the sixth pipeline is greater than the pressure of the fourth pipeline, the output end of the second driving assembly will retract. During the retraction time of the output end of the second driving assembly, the second section will no longer be in a tightened state. Therefore, the output end of the first driving assembly will further extend outwards under the drive of the third pipeline, making the second section in a tightened state again. During the above process, the second section will move upwards as a whole, thereby achieving the upward cutting movement of the second section.

[0031] Finally, the fifth pipeline is controlled to be connected through the switching valve, and at this time, the sixth pipeline is disconnected. Since the pressure in the fifth pipeline is greater than that in the third pipeline, the output end of the first driving component will retract. During the retraction of the output end of the first driving component, the second section will no longer be in a taut state. Therefore, the output end of the second driving component will extend outward under the drive of the third pipeline, making the second section taut again. During the above process, the second section will move downward as a whole, thereby achieving the movement of downward cutting of the second section.

[0032] In addition, during the use of the wire saw cutting machine in this case, if it is found that the second section is worn, the second section can be quickly replaced. The specific principle is as follows:

[0033] Disconnect the first pipeline and the second pipeline, so that the first clamping component and the second clamping component loosen the wire saw respectively. At the same time, control the wire feeding component and the wire taking-up component to work, so that the wire saw moves towards the wire taking-up component, thereby achieving the purpose of moving the second section and realizing the effect of quickly replacing the second section.

[0034] Through the wire saw cutting machine and its control method in this case, not only can the reciprocating movement of the wire saw be realized, but also the cutting part of the wire saw can be quickly and conveniently replaced, which has good practicability. Description of the Drawings

[0064] As shown by Figure 3 As shown in the figure, the wire saw cutting machine in this case is provided with multiple wire saws 300. The multiple wire saws 300 are provided with gaps and have a certain included angle with each other. During the specific processing process, the multiple wire saws 300 can not only improve the processing efficiency, but also perform more complex processing.

[0065] As shown by Figure 4As shown, in this embodiment, the control mechanism includes a pressure supply source 600, a first pipeline G1, a second pipeline G2, a third pipeline G3, a fourth pipeline G4, a fifth pipeline G5, a sixth pipeline G6, and a switching valve K5 connected to the pressure supply source 600.

In this case, the pressure source is a gas source. In another embodiment, the pressure source can be a liquid supply source, such as an oil pump, which will not be elaborated here.

[0066] Among them, the third pipeline G3 and the fourth pipeline G4 can be used to respectively drive the output ends of the first driving assembly 412 and the second driving assembly 422 to extend outwards, the fifth pipeline G5 and the sixth pipeline G6 can be used to respectively drive the output ends of the first driving assembly 412 and the second driving assembly 422 to contract inwards, the pressure of the fifth pipeline G5 is greater than the pressure of the third pipeline G3, and the pressure of the sixth pipeline G6 is greater than the pressure of the fourth pipeline G4.

[0067] Furthermore, as Figure 4 shown, the control mechanism further includes a first pressure regulating valve B1, a second pressure regulating valve B2, and a third pressure regulating valve B3 respectively connected to the pressure supply source 600. The first pipeline G1 and the second pipeline G2 are connected to the first pressure regulating valve B1 in parallel, the third pipeline G3 and the fourth pipeline G4 are connected to the second pressure regulating valve B2 in parallel, and the switching valve K5 is connected to the pressure supply source 600 in a way that it is connected to the third pressure regulating valve B3.

[0068] In addition, the control mechanism further includes a first on-off valve K1, a second on-off valve K2, a third on-off valve K3, and a fourth on-off valve K4.

[0070] As Figure 4As shown, each wire saw 300 includes a first section 310 located between the wire pay-off assembly 220 and the second clamping assembly 421, a second section 320 located between the second clamping assembly 421 and the first clamping assembly 411, and a third section 330 located between the first clamping assembly 411 and the wire take-up assembly 210. The second section 320 is used to cut the workpiece 500. Specifically, the specific control method of the wire saw cutting machine in this case includes three steps: tensioning the wire saw 300, moving up and down for cutting, and replacing the second section 320, which will be described in detail as follows:

[0071] From Figures 4 to 10 , and Figure 12 As shown, the control method for tensioning the wire saw 300 is as follows:

[0072] S1: Control the output ends of the first driving assembly 412 and the second driving assembly 422 to extend outwards respectively. Specifically, from Figure 4 and Figure 12 As shown, turn on the third on-off valve K3, turn off the first on-off valve K1, the second on-off valve K2, and the fourth on-off valve K4, and let the output ends of the first driving assembly 412 and the second driving assembly 422 extend outwards under the action of the third pipeline G3 and the fourth pipeline G4 respectively.

[0073] S2: Control the output end of the first driving assembly 412 to retract, and control the output end of the second driving assembly 422 to remain in the extended state. Specifically, from Figure 5 As shown, turn off the third on-off valve K3, and let the third pipeline G3 and the fourth pipeline G4 be connected to the atmosphere through the third on-off valve K3. The output end of the first driving assembly 412 retracts under the action of gravity, and the output end of the second driving assembly 422 remains in the extended state.

[0074] S3: Control the second clamping assembly 421 to clamp the wire saw 300, and control the wire pay-off and take-up mechanism 200 to tension the second section 320 and the third section 330. Specifically, from Figure 5 , Figure 6 , Figure 7 , and Figure 13 As shown, turn on the second on-off valve K2, and through the second pipeline G2, let the second clamping assembly 421 work and clamp the wire saw 300. Then control the wire take-up wheel 211 and the wire pay-off wheel 221 to rotate clockwise for m circles to tension the second section 320 and the third section 330.

[0075] S4: Control both the first clamping assembly 411 and the second clamping assembly 421 to clamp the wire saw 300, and control the wire pay-off and take-up mechanism 200 to slacken the first section 310 and the third section 330. Specifically, from Figure 8 , Figure 9 , and Figure 14As shown, turn on the first on-off valve K1 and the second on-off valve K2. Through the first pipeline G1 and the second pipeline G2, make the first clamping assembly 411 and the second clamping assembly 421 work and clamp the wire saw 300 respectively. Then control the wire take-up wheel 211 and the wire pay-off wheel 221 to rotate counterclockwise for n turns to slacken the first section 310 and the third section 330.

[0076] S5: Control the output end of the first driving assembly 412 to extend outwards, and control the output ends of the first driving assembly 412 and the second driving assembly 422 to remain in the state of extending outwards to tighten the second section 320. Specifically, as shown by Figure 10 and Figure 15 turn on the third on-off valve K3. Through the third pipeline G3 and the fourth pipeline G4, make the output ends of the first driving assembly 412 and the second driving assembly 422 remain in the state of extending outwards, and make the second section 320 in a tightened state.

[0077] As shown by Figure 16 and Figure 17 the control method for the up-and-down cutting movement of the wire saw 300 is as follows:

[0078] P1: Tighten the wire saw 300. Specifically, through the above steps S1 to S5, tighten the wire saw 300 to make the second section 320 in a tightened state.

[0079] P2: Control the third pipeline G3 and the fourth pipeline G4 to be connected. Specifically, control the third on-off valve K3 to be connected to make the third pipeline G3 and the fourth pipeline G4 connected, and make the output ends of the first driving assembly 412 and the second driving assembly 422 both in the state of extending outwards. Since and at this time limited by the tightened second section 320, the output end of the first driving assembly 412 does not move outwards to the limit.

[0080] P3: Control the switching valve K5 to switch to the sixth pipeline G6 to drive the output end of the first driving assembly 412 to extend outwards, drive the output end of the second driving assembly 422 to retract, and drive the second section 320 to cut upwards. Specifically, as shown by Figure 16 control the switching valve K5 to work to connect the switching valve K5 and the sixth pipeline G6. At this time, the fifth pipeline G5 is disconnected. Since the pressure of the sixth pipeline G6 is greater than the pressure of the fourth pipeline G4, the output end of the second driving assembly 422 will retract. During the time when the output end of the second driving assembly 422 retracts, it will cause the second section 320 to no longer be in a tightened state. Therefore, the output end of the first driving assembly 412 will further extend outwards under the drive of the third pipeline G3 to make the second section 320 in a tightened state again. During the above process, it will cause the second section 320 to move upwards as a whole, thereby achieving the upward cutting movement of the second section 320.

[0081] P4: The switching valve K5 switches to the fifth pipeline G5 to drive the output end of the first driving component 412 to retract, drive the output end of the second driving component 422 to extend outwards, and drive the second section 320 to cut downwards. Specifically, by Figure 17 As shown, control the switching valve K5 to work so that the switching valve K5 is connected to the fifth pipeline G5, and at this time, the sixth pipeline G6 is disconnected. Since the pressure of the fifth pipeline G5 is greater than that of the third pipeline G3, the output end of the first driving component 412 will retract. During the retraction of the output end of the first driving component 412, the second section 320 will no longer be in a taut state. Therefore, the output end of the second driving component 422 will extend outwards under the drive of the third pipeline G3 to make the second section 320 in a taut state again. During the above process, the second section 320 will move downwards as a whole, thereby achieving the movement of the second section 320 to cut downwards.

[0082] Finally, by repeatedly switching the connection between the switching valve K5 and the fifth pipeline G5 and the sixth pipeline G6, the second section 320 can be driven to move up and down reciprocally, thereby achieving the cutting purpose.

[0083] By Figure 11 As shown, for the wire saw cutting machine in this case, the control method for replacing the second section 320 is as follows:

[0084] Q1: Control both the first clamping component 411 and the second clamping component 421 to release the wire saw 300. Specifically, by disconnecting the first on-off valve K1 and the second on-off valve K2, both the first clamping component 411 and the second clamping component 421 release the wire saw 300.

[0085] Q2: Control the wire feeding component 220 to feed wire and control the wire winding component 210 to wind wire so that the second section 320 moves towards the wire winding component 210 to switch the second section 320. Specifically, by Figure 11 As shown, control the wire winding wheel 211 and the wire feeding wheel 221 to rotate clockwise synchronously for P turns to make the wire saw 300 move clockwise as a whole to achieve the purpose of switching the second section 320.

[0086] In addition, it should be noted that the first pressure regulating valve B1, the second pressure regulating valve B2, the third pressure regulating valve B3, the first on-off valve K1, the second on-off valve K2, the third on-off valve K3, the fourth on-off valve K4, and the switching valve K5 in this case are all electrically connected to the control chip. The above valve bodies are electrically connected to the control chip, and the working states of different valve bodies are controlled through the control chip, which belongs to the existing conventional technology in this field and will not be elaborated here.

[0087] Through the above solution of this embodiment, the wire saw cutting machine in this case not only has a simple structure, but also can achieve the purpose of reciprocating up and down of the wire saw 300 to cut the workpiece 500, improving the durable usability of the wire saw 300. When it is found that the part of the wire saw 300 used for cutting is worn, it can also be conveniently switched to allow the normal part of the wire saw 300 to continue to be used for cutting without replacing the entire wire saw 300, improving the durable usability of the wire saw 300.
