Description

Technical Field

[0001] The utility model relates to the field of wire cutting machines, in particular to a wire cutting component to prevent wire breakage and a multi-wire cutting machine using the component. Background Art

[0002] Traditional stone cutting generally uses saw blades, rope saws, band saws and other materials with alloy blades for processing. Carbide has a certain thickness, so traditional tools will form saw seams ranging from 3-10mm in the process of cutting stone. In addition, the carbide tool has a large vibration when in rigid contact with the stone during processing, which easily causes the stone to break during processing. Generally, it can only process plates with a thickness of more than 10mm. Diamond wire has flexible contact with the stone, there is no instantaneous impact load, low vibration and noise, and the wire diameter is small, and the cutting seam is less than 1mm, which can not only greatly improve the yield rate, but also can directly process thin plates with a thickness of less than 5mm on the rough material without causing the stone to break during the cutting process. If you want to use diamond wire to cut stone and achieve good results, you need to use a larger wire diameter to reduce the wire breakage rate during the cutting process. At the same time, the large-diameter diamond wire also needs to match a larger tension to ensure the tension of the diamond wire. The existing multi-wire cutting machine uses a motor to control the speed of the roller alone to ensure the tension. However, due to the stacking of coils on the pay-off roller, the length of the cutting wire released each time the pay-off roller rotates is inconsistent. When cutting, it is easy to produce a wire bow problem (the wire bow phenomenon, that is, the bending deformation caused by the uneven tension of the cutting wire on different wire wheels, will seriously affect the cutting straightness and the flatness of the cutting surface).

[0003] Prior art CN202310101817.7 discloses a cutting device and a multi-wire cutting machine for a large stone slab. It includes a frame and a cutting frame; the cutting frame includes a first pay-and-reel mechanism, a second pay-and-reel mechanism, a first main guide wheel, a second main guide wheel, a third main guide wheel, a fourth main guide wheel and a guide wheel driving mechanism, the four main guide wheels extend in the horizontal longitudinal direction and are rotatably connected to the frame at both ends of the axis, the second pay-and-reel mechanism is located on the other lateral side of the frame, the first pay-and-reel mechanism and the second pay-and-reel mechanism both include pay-and-reel wheels, wire wheel driving components, wire arrangement wheels, wire arrangement devices, tension wheels, tension adjustment devices, in-and-out wire wheels and wire routing mechanisms; one end of the diamond wire is connected to the pay-and-reel wheel, and is connected to the corresponding main guide wheel after passing through the wire arrangement wheel, tension wheel and in-and-out wire wheels in sequence. Although the utility model solves the problem of insufficient tension by setting a tension wheel, the following problems still exist:

[0004] 1. The wire arrangement wheel, tension wheel and in-and-out wire wheel of the utility model are all driven by the cutting wire itself to rotate. The different diameters of the wire wheels during the operation of the cutting wire lead to differences in the speed and torque of the wire wheels. Especially in high-speed continuous cutting operations, the change in the torque of the wire wheels may generate excessive local tension in certain areas, increasing the risk of diamond wire breakage. Such unevenness may also cause the trajectory of the cutting wire to be unstable during the cutting process, affecting the cutting accuracy and efficiency.

[0005] 2. The existing tension wheel adjusts the tension by swinging the tension wheel to achieve tensioning of the cutting wire. However, the tension changes caused by the stacking of coils on the pay-off roller are difficult to accurately control only through traditional mechanical adjustment methods. The existing adjustment mechanism may not be able to respond quickly to these dynamic changes, resulting in inaccurate tension control, affecting cutting accuracy and wire life. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a wire cutting component that prevents wire breakage and a multi-wire cutting machine using the component, which accurately controls the rotation speed of the drive motor and the servo motor through the control system, thereby adjusting the linear speed of the cutting wire on the roller and the tension wheel, thereby realizing dynamic adjustment of the cutting wire tension, ensuring that the cutting wire maintains an appropriate and stable tension during the cutting process, reducing the risk of wire breakage caused by tension fluctuations, and thus improving production efficiency.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a wire cutting assembly for preventing wire breakage, comprising: a cutting frame, a plurality of rollers, a driving motor, a wire-retracting and -releasing mechanism, and a tension assembly, wherein the rollers are correspondingly arranged on the cutting frame and are respectively connected to the driving motors, the wire-retracting and -releasing mechanisms are respectively correspondingly arranged on both sides of the cutting frame and are respectively connected to both ends of the cutting wire, and the tension assembly is correspondingly arranged on the cutting frame and the wire-retracting and -releasing mechanism is capable of tensioning the cutting wire;

[0009] The tension assembly includes a tension wheel, a servo motor and a correction wheel. The servo motor is fixed on the cutting frame. The tension wheel is arranged on the cutting frame corresponding to the cutting line inlet and outlet of the roller corresponding to the correction wheel. The cutting line is wound in an M shape on the correction wheel, the wire reeling and winding mechanism and the tension wheel, and the cutting line tension can be controlled by controlling the rotation speed of the driving motor and the servo motor.

[0010] It should be noted that the existing tension assembly will cause the cutting line tension to continuously change during the swinging process of the tension wheel, and because the tension wheel is always rotating driven by the cutting line, when the tension changes, the friction between the cutting line and the tension wheel will also change, which can easily cause the cutting line to break; therefore, this solution adopts a tension wheel with a fixed position, and uses the servo motor in the tension assembly to accurately control the rotation speed of the tension wheel, and uses the drive motor to control the rotation speed of the roller to keep the cutting line at a consistent linear speed on the tension wheel and the roller, thereby preventing the friction of the tension wheel itself from affecting the linear speed of the cutting line, and ensuring that the tension of the cutting line is stable during the cutting process. Reduce the risk of wire breakage caused by tension fluctuations; the design of the correction wheel helps to correct the deviation of the cutting line at the inlet and outlet of the roller and maintain the straightness of the cutting line; and the cutting line of this scheme is arranged in an M shape on the correction wheel, the wire retracting and releasing mechanism and the tension wheel, which can increase the contact area between the cutting material and the tension wheel, thereby increasing the friction resistance between the cutting material and the tension wheel, ensuring that the speed of the cutting line at the tension wheel can remain consistent, significantly reducing the wire bow phenomenon, improving the cutting straightness and the flatness of the cutting surface, reducing the risk of diamond wire breakage due to uneven tension, improving cutting accuracy and efficiency, and extending the service life of the diamond wire.

[0016] It should be noted that the translation mechanism enables the pay-off and take-up wheel to move along the axial direction of the winding mechanism, so that the cutting line can be dynamically adjusted through the pay-off and take-up wheel, ensuring the smoothness of the cutting line during the pay-off and take-up process, reducing the problem of uncertain tension changes caused by coil stacking, reducing the risk of cutting line breakage, and improving cutting quality and production efficiency.

[0023] It should be noted that the cooling device of the existing wire cutting device does not cool the cutting lines arranged on the rollers individually, but sprays coolant as a whole, and the cooling effect is low. The present solution arranges the cooling pipeline above the corresponding roller so that it keeps a closer distance to the cutting lines on the cutting surface, and arranges liquid outlets on the cooling pipeline corresponding to the cutting lines, so that the coolant sprayed from each liquid outlet can cool the corresponding cutting line.

[0051] The working principle and use method of a wire cutting assembly for preventing wire breakage in this embodiment:

[0052] The present embodiment provides a wire cutting component that prevents wire breakage, which uses a servo motor 51 to accurately control the rotation speed of a tension wheel 52 to adjust the tension of the cutting wire. When the servo motor 51 is started, the tension wheel 52 rotates accordingly to move the cutting wire accordingly. The rotation speeds of the drive motor 3 and the servo motor 51 are accurately adjusted by the control system 8, so that the tension of the cutting wire on the roller 2 and the tension wheel 52 can be dynamically adjusted to ensure that the cutting wire maintains an optimal tension level during the cutting process, thereby reducing the problem of wire breakage caused by tension fluctuations caused by the wire retracting and releasing mechanism 4; the deviation correction wheel 53 cooperates with the tension wheel 52 to ensure stable guidance of the cutting wire on the cutting frame 1, and the deviation correction wheel 53 is set at the cutting wire inlet and outlet position of the roller 2, which can help correct the deviation of the cutting wire when entering and exiting the roller 2, ensuring that the cutting wire maintains a straight path during movement, reducing the wire bow phenomenon, and ensuring Cutting straightness and flatness of the cutting surface; the roller 2 is connected to the driving motor 3 by connecting the block 21, and the rotation of the driving motor 3 drives the roller 2 to rotate, thereby realizing the continuous supply of the cutting line; the other end of the roller 2 is equipped with a quick-release device 22, which is convenient for quick replacement and maintenance; it not only simplifies the maintenance process, but also ensures the efficient transmission connection between the roller 2 and the driving motor 3, thereby controlling the conveying speed of the cutting line on the roller 2; the reel 41 is located on the translation mechanism 42, and moves horizontally in the axial direction of the winding mechanism 43 through the translation mechanism 42. It can be adjusted in time with the change of the length of the cutting line to ensure the balance of the tension of the cutting line. The moving speed of the translation mechanism 42 is monitored by the detection wheel 413. The detection wheel 413 senses the deflection of the cutting line and feeds back to the control system 8, thereby adjusting the moving speed of the translation mechanism 42 to ensure that the reeling and unreeling of the cutting line are always in an ideal tension state.

[0053] When in use, first fix the roller 2 in the mounting hole 111 of the cutting frame 1 through the quick-release device 22 and the connecting block 21 to ensure that the roller 2 can rotate freely and is firmly connected; and install the drive motor 3 on the corresponding connecting block 21 to make the drive motor 3 and the roller 2 transmission connected, and then install the wire-retracting and unwinding mechanism 4 on the fixed frames 11 on both sides of the cutting frame 1 respectively, and the correcting wheel 53 is installed on the fixed frame 11 corresponding to the cutting line inlet and outlet of the cutting frame 1, and is located above the wire-retracting and unwinding mechanism 4.

[0056] A platform 10 is disposed around the outer side of the frame 6 , and the control system 8 can control the rotation speed of the servo motor 51 and the drive motor 3 , thereby controlling the rotation speed of the roller 2 and the tension wheel 52 .

[0058] The platform 10 is arranged around the middle of the frame 6 , the platform 10 is fixed on the frame 6 , and a ladder 101 is vertically arranged axially along the outer side surface of the frame 6 at the connection between the platform 10 and the frame 6 .

[0059] The platform 10 is also provided with a safety guardrail 102 , and the safety guardrail 102 is arranged around the edge of the platform 10 .

[0061] The working principle and use method of a multi-wire cutting machine of this embodiment:

[0062] The multi-wire cutting machine provided in this embodiment can realize precise position adjustment of the cutting assembly through the control system 8 and the lifting device 61; the control system 8 can not only adjust the rotation speed of the servo motor 51 and the drive motor 3 to accurately adjust the rotation speed of the roller 2 and the tension wheel 52 to ensure that the cutting line maintains a constant and appropriate tension during the cutting process, but also control the lifting device 61 to move the cutting assembly up and down according to the processing requirements; the cooling device 9 can cool the cutting line during cutting, and the circulating pump 91 cooperates with the control system 8 through electrical connection to promote the coolant to flow in the connecting pipe 92, and finally transports the coolant to the cutting line through the cooling pipe 93 arranged along the axial direction of the roller 2, so that the coolant directly acts on the cutting line, effectively removing the coolant generated during cutting. The design of the liquid outlet 931 ensures that the coolant can evenly cover the cutting line, reduces the deformation of the cutting line caused by thermal expansion, and extends the service life of the diamond wire; the surrounding walkway 10 in the middle of the frame 6 provides the operator with a spacious observation and operation space, and the walkway 10 is firmly connected to the frame 6 to ensure stability and safety during operation. The set ladder 101 makes it convenient for operators to go up and down the walkway 10, and the safety guardrail 102 surrounds the edge of the walkway 10, effectively preventing accidental falls and enhancing operation safety; by installing the slide rail 71 and the crane 72 on the guide rail base 7, the frame 6 is quickly positioned and moved, which greatly improves the flexibility and efficiency of large workpiece processing and reduces the time cost of material handling and positioning.

[0063] When in use, first ensure that all motors, control systems 8 and tension components 5 have been correctly installed and debugged. The cutting line must be correctly installed on the roller 2, the correction wheel 53 and the reel 41 to form an M-shaped path.

At the same time, the cooling device 9 is started to cool the cutting line. During the cutting process, the detection wheel 413 continuously monitors the state of the cutting line. If deflection is detected, the control system 8 will automatically adjust the translation mechanism 42 to correct the offset and keep the tension of the cutting line stable. After the operation is completed, when the roller 2 needs to be replaced or maintained, the operator can quickly use the quick-release device 22 to disassemble the roller 2, and reinstall it after maintenance is completed to reduce downtime.
