Description

Technical Field

[0001] The present invention relates to the field of cutting machinery, and particularly to a wire cutting assembly and a lifting multi-wire cutting sawing machine using the assembly. Background Art

[0002] At present, with the development of diamond wire cutting machine tools, diamond wire multi-wire cutting machine tools have been gradually applied to the stone processing industry. In stone processing, the processing of super-large-size stones has always been a difficult point in the cutting processing industry. Diamond wire stone cutting machines use diamond wires to process natural stones or other large-sized materials. The sizes and weights of stone blocks are much larger. Therefore, a single cutting wire may not be able to complete the cutting of large stones, and it is often necessary to pause and change the wire, which will result in wire marks left on the cutting surface, greatly affecting the cutting quality.

[0003] The prior art CN202410742031.8 discloses a segmented wire cutting assembly and a wire saw. It includes a mounting frame, two or more main guide wheels rotatably arranged on the mounting frame, and two sets of wire winding and unwinding systems; each set of wire winding and unwinding system has a rotatable wire winding and unwinding wheel, and the number of wire winding and unwinding wheels in each set of wire winding and unwinding system is two or more, so as to be able to control two or more cutting wires respectively, and two or more cutting wires are wound around the main guide wheel separately; each set of wire winding and unwinding system includes a tension mechanism, and the tension mechanism includes two or more tension wheels for respectively adjusting the tightness of each cutting wire and a tension driving component; the tension wheels are movably connected to the mounting frame, and the tension driving component adjusts the movement of each tension wheel so that the tensions of each cutting wire are kept consistent; although this invention uses multiple groups of cutting wires for segmented cutting, there are still the following problems: 1. In this solution, since both the wire winding device and the wire unwinding device use one motor to drive multiple wire winding and unwinding wheels to operate, during the actual cutting process, the resistances borne by different cutting wires may be different, resulting in inconsistent tensions of different cutting wires. It is difficult to flexibly adjust the speeds of each wire winding and unwinding wheel according to the actual situation, resulting in some cutting wires being too tight or too loose. The too-tight cutting wires are prone to breakage, which not only wastes materials but may also pose a safety hazard; while the too-loose cutting wires may lead to low cutting efficiency and obvious marks or defects left on the cutting surface, affecting the quality of the final product.

[0004] 2. Driving multiple wire winding and unwinding wheels by one motor will cause the motor to bear a large load. Especially in the high-load working state, it may cause the motor to operate overloaded, increase energy consumption, and shorten the service life of the motor. At the same time, due to the uneven force on each wire wheel, it will also accelerate the wear of some components and increase the maintenance cost. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a wire cutting component and a lifting multi-wire cutting sawing machine using the component. By arranging a plurality of wire pay-off devices and wire take-up devices, the simultaneous operation of multiple cutting wires can be realized, avoiding the decline of cutting quality caused by uneven wire tension, and improving the cutting accuracy and efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: Provide a wire cutting component, including: a cutting frame, rollers, a wire pay-off and take-up component, and a tensioning component. The rollers are symmetrically arranged on the cutting frame; At least two groups of wire pay-off and take-up components are arranged on the cutting frame. The wire pay-off and take-up component includes a wire pay-off device and a wire take-up device. At least two cutting wires are wound around the rollers at intervals corresponding to the wire pay-off and take-up components, and the winding directions of all the cutting wires are the same. Each cutting wire wound around the roller forms a cutting subnet, and the cutting subnets are combined to form the cutting mesh surface of the sawing machine. The wire pay-off device and the wire take-up device are arranged on the cutting frame corresponding to the two ends of the cutting wire, and one wire take-up device and one wire pay-off device control the pay-off and take-up of one cutting wire respectively. The tensioning component is arranged on the cutting frame corresponding to the wire pay-off device and the wire take-up device, and can tension the cutting wire wound around the roller. Moreover, the wire pay-off device can cooperate with the wire take-up device of another wire pay-off and take-up component to adjust the length of a single cutting wire wound around the roller, so as to wind and form cutting subnets of various different specifications.

[0007] It should be noted that the cutting frame is the core structure for installing all cutting-related components. The position of the cutting frame is fixed at the upper end of the chassis, ensuring the stability required during the cutting process. The rollers are symmetrically arranged on the cutting frame and serve as guide wheels for the cutting wire. They help maintain the path of the cutting wire and support the stable operation of the cutting wire under high-speed rotation. The wire winding and unwinding assembly includes an independent wire unwinding device and a corresponding wire winding device. Each wire unwinding device and wire winding device work in pairs to control a single cutting wire. This design allows each cutting wire to adjust its speed and tension according to actual needs, avoiding the common problem of uneven tension in the traditional single-motor-driven multi-cutting-wire system. The tensioning assembly is arranged on the cutting frame and is responsible for maintaining the appropriate tension of the cutting wire wound around the rollers. This helps ensure the consistency and accuracy of cutting, while preventing the cutting wire from deviating from the predetermined path due to being too loose or breaking due to being too tight. Moreover, the cutting mesh surface of the wire saw machine is composed of cutting sub-meshes formed by winding each cutting wire. Each cutting sub-mesh is relatively independent, so the cutting sub-meshes do not affect each other, improving the cutting quality. This solution greatly improves the working efficiency by using multiple cutting wires for cutting simultaneously, and is especially suitable for large-scale production or the processing of super-large-sized materials. Independently controlling the speed and tension of each cutting wire reduces the defects that may appear on the cutting surface, improves the quality of the final product. Moreover, compared with the high-load operation of the single-motor-driven multi-wheel system, the decentralized power sources reduce the wear of each component, extend the service life, and thus reduce the long-term maintenance cost.

[0008] Preferably, the number N of the wire winding and unwinding assemblies is 2 to 8 groups. The wire winding devices and wire unwinding devices are respectively arranged at intervals on both sides of the cutting frame and are integrally arranged in a staggered manner on the cutting frame.

[0009] It should be noted that the positions of the wire winding device and the wire unwinding device on the cutting frame are not simply arranged in a straight line, but form an S-shaped staggered pattern, which can evenly wind different cutting wires around the rollers. And by changing the cooperation relationship with different wire winding devices, the length of the cutting wire wound around the rollers can be flexibly adjusted. That is, the first wire unwinding device is docked with the first wire winding device, and the first cutting wire is wound around the first section of the roller. When the first wire unwinding device is docked with the second wire winding device, the first cutting wire is wound around the first and second sections of the roller. This means that the operator can dynamically adjust the cutting parameters according to the specific size and shape of the workpiece, control the length of the cutting wire winding, so as to ensure the best cutting effect. Preferably, the number N of the wire winding and unwinding assemblies is 2 to 8 groups, and the composition types of the cutting mesh surface formed by winding the cutting wires are (the number of factors of N) kinds. Preferably, the composition types of the cutting mesh surface formed by winding the cutting wires are switched among (the number of factors of N - 1) kinds.

[0010] Preferably, there are two sets of wire winding and unwinding assemblies; the wire winding device includes a wire winding motor and a wire winding wheel arranged on the rotating shaft of the wire winding motor, and the wire unwinding device includes a wire unwinding motor and a wire unwinding wheel arranged on the rotating shaft of the wire unwinding motor. The two wire unwinding motors are installed on one side of the cutting frame corresponding to the positions of one end and the middle of the roller, and the two wire winding motors are installed on the other side of the cutting frame corresponding to the positions of the middle and the other end of the roller. Moreover, the positions of the wire winding wheel and the wire unwinding wheel are arranged in an S shape as a whole.

[0011] It should be noted that both the two wire unwinding devices and the two wire winding devices include a motor (wire unwinding motor or wire winding motor) and a wheel (wire unwinding wheel or wire winding wheel) installed on its rotating shaft. Such a configuration allows each cutting wire to be independently controlled, thereby precisely adjusting the tension of each cutting wire; and since the wire winding device and the wire unwinding device are arranged in an S-shaped staggered manner, when the cutting wire is led out from the wire unwinding wheel and recovered by the wire winding wheel after passing through the roller, it will occupy half of the length on the roller for winding. In this way, the two cutting wires of the two sets of devices evenly divide the roller into two parts, improving the flexibility during the cutting process.

[0012] Preferably, the tensioning assembly includes a wire arranging device, a tensioning wheel and a deviation correcting wheel. The wire arranging device, the tensioning wheel and the deviation correcting wheel are arranged in a V shape as a whole on the cutting frame.

The wire arranging device is correspondingly arranged above the wire winding device or the wire unwinding device, and is used to guide the cutting wire to wind and arrange orderly on the corresponding wire winding and unwinding assemblies. The tensioning wheel: is arranged on one side of the wire arranging device and is responsible for providing appropriate tension to the cutting wire to maintain its constant tension. The deviation correcting wheel is arranged corresponding to the position where the cutting wire enters the roller and is used to correct the path deviation of the cutting wire to ensure that it accurately enters the roller and maintains the correct winding angle.

[0014] Preferably, the cutting frame includes a support beam and a fixing frame.

[0017] It should be noted that the four columns are arranged in a square shape on the base, providing a solid supporting foundation for the entire machine. This layout can disperse the weight and prevent structural deformation or damage caused by excessive force on a single point; the four corners of the lower end of the cutting frame are fixed on four columns, which not only increases the stability of the cutting frame, but also ensures that it will not shake or shift during the cutting process, thereby improving the cutting accuracy; a lifting slot for setting up a lifting device is provided in the middle of the column, so that the lifting frame can move smoothly in the vertical direction; a leveling plate is provided on the outside of the column to facilitate the adjustment and calibration of the verticality of the column to ensure the installation accuracy of the entire equipment.

The lifting screw rods are located in the lifting grooves of the columns. When the driving mechanism is started, the screw rods rotate, thereby driving the lifting frame that is thread - fitted with them to move up and down. The guiding slide rails are fixed on the surface of the columns and match with the sliders or guide grooves on the lifting frame to ensure that the lifting frame always remains vertical during movement, preventing deviation or shaking; the screw rod transmission system has high mechanical efficiency and load - bearing capacity, and is suitable for handling the lifting requirements of heavy - load workpieces; compared with hydraulic or pneumatic systems, the structure of the screw rod transmission system is relatively simple, easy to maintain and inspect, and reduces the long - term operation cost.

The positioning sliding grooves are arranged on both sides of the support platform and are in mutual contact with the guiding slide rails on the columns to ensure that the lifting frame maintains a straight - line movement during vertical movement. The clamping devices are installed on the support platform to fix the workpiece and prevent it from displacing or vibrating during the lifting or cutting process. Through the combined action of the support platform and the clamping devices, it is ensured that the workpiece does not move or vibrate during the entire cutting process, thereby improving the cutting quality.

This not only avoids the problem of uneven tension that may occur when a traditional single motor drives multiple cutting wires 32, but also adjusts the length of each cutting wire 32 wound around the roller 3 through the cooperation of the wire pay-off device 41 and different wire take-up devices 42, so as to adapt to the cutting of materials of different specifications; The tensioning assembly 5 includes a wire arranging device 51, a tensioning wheel 52 and a deviation correcting wheel 53, which are arranged on the cutting frame 2 in a V-shaped arrangement as a whole; the wire arranging device 51 is correspondingly arranged above the wire take-up device 42 or the wire pay-off device 41 and is used to guide the cutting wires 32 to be arranged orderly; the tensioning wheel 52 is arranged on one side of the wire arranging device 51 and is responsible for applying an appropriate pressure to the cutting wires 32 to maintain a constant tension; the deviation correcting wheel 53 is arranged corresponding to the position where the cutting wire 32 enters the roller 3 and is used to correct the path deviation of the cutting wire 32 to ensure that it accurately enters the roller 3 and maintains the correct winding angle; The lifting frame 6 is arranged directly below the cutting frame 2 through a lifting screw rod 71, a driving mechanism 72 and a guiding slide rail 73. The lifting screw rod 71 is correspondingly arranged in the lifting groove 111 of the column 11 and serves as the main transmission component for the vertical movement of the lifting frame 6. The driving mechanism 72 is arranged on the connecting cross beam 12 between the columns 11 and transmits power to the lifting screw rods 71 in each column 11 through a connecting rod 74. When the driving mechanism 72 is started, the screw rod rotates to drive the lifting frame 6 engaged with its thread to move up and down; the guiding slide rail 73 is correspondingly arranged vertically on the surface of the column 11 close to the lifting frame 6 and is matched with the slider or guide groove on the lifting frame 6 to ensure that the lifting frame 6 always maintains a vertical direction during the movement process and prevent deviation or shaking; the clamping device 63 is arranged on the support platform 61 of the lifting frame 6 and is used to fix the workpiece to prevent it from displacing or vibrating during the lifting process or the cutting process. The clamping device 63 can be adjusted according to the shape and size of the workpiece to ensure that the workpiece remains stable and immovable during the entire cutting process, improving the cutting quality and efficiency; The walkway is arranged on the base 13 around the bottom of the cutting frame 2, providing a safe operating platform. The ladder 81 is arranged on one side of the walkway 8 to facilitate the operator to get on and off the walkway 8. The control system 9 is installed on the walkway 8 and is electrically connected to each component of the band sawing machine to achieve centralized control and monitoring. The operator can start and stop the machine through the control system 9, adjust the cutting parameters (such as speed, tension, etc.), and monitor the operating status of the equipment. The cooling device 10 is also arranged on the walkway 8, and its liquid outlet end is correspondingly arranged on the cutting frame 2 corresponding to the cutting wire 32 and is used to reduce the temperature of the cutting area and extend the service life of the cutting wire 32 and other components.

[0052] During use, first confirm that the main components such as the chassis 1, cutting frame 2, rollers 3, wire pay-off and take-up assembly 4, tensioning assembly 5, and lifting frame 6 are firmly installed without looseness or damage. Check whether the lifting device 7, drive motor 31, control system 9, and cooling device 10 are operating normally. Lead the cutting wire 32 from the pay-off wheel 412 of the pay-off device 41 to the tensioning assembly 5 (wire arranging device 51, tensioning wheel 52, and deviation correction wheel 53), and wind it around the rollers 3 in sequence. According to the size and shape of the workpiece, adjust the cooperation relationship between the pay-off device 41 and the take-up device 42 to ensure that the length of the cutting wire 32 wound around the rollers 3 is suitable for the cutting requirements. Then, guide it to the take-up wheel 422 of the take-up device 42 through the tensioning assembly 5 to ensure that the tension of each cutting wire 32 is uniform, avoiding being too loose or too tight. Next, place the workpiece to be cut on the support platform 61 of the lifting frame 6, and firmly fix the workpiece using the clamping device 63 to prevent it from displacing or vibrating during cutting. Start the lifting device 7 through the control system 9, and drive the lifting screw rod 71 to drive the lifting frame 6 to move vertically along the guide slide rail 73 to adjust the workpiece to the cutting position of the cutting wire 32, ensuring that the contact surface between the workpiece and the cutting wire 32 is parallel to avoid uneven cutting caused by inclination. Then, control the pay-off and take-up speed and tension of the cutting wire 32 through the control system 9 to ensure that the cutting wire 32 operates in the best state. Observe the cutting process to ensure that the path of the cutting wire 32 is correct without deviation or breakage. At the same time, use the cooling device 10 to reduce the temperature of the cutting area to prevent the cutting wire 32 from being damaged due to overheating. After cutting, turn off the drive motor 31, wire pay-off and take-up assembly 4, and cooling device 10 in sequence, lower the lifting frame 6 to the lowest position, loosen the clamping device 63, and remove the cut material. When the cutting material is relatively thin, only the pay-off device 41 of the first wire pay-off and take-up assembly 4 and the take-up device 42 of the second wire pay-off and take-up assembly 4 can be used in cooperation to wind the cutting wire 32, thereby reducing energy consumption.

[0053] Embodiment 2 As Figure 9 and Figure 10 shown, a lifting multi-wire cutting wire saw machine includes: a chassis 1, a cutting frame 2, rollers 3, a wire pay-off and take-up assembly 4, a tensioning assembly 5, and a lifting frame 6. The cutting frame 2 is arranged at the upper end of the chassis 1. The lifting frame 6 is arranged directly below the cutting frame 2 through a lifting device 7 and can approach the cutting frame 2 through the lifting device 7. The rollers 3 are symmetrically arranged on the cutting frame 2. Four sets of wire winding and unwinding assemblies 4 are provided on the cutting frame 2. The wire winding and unwinding assembly 4 includes a wire unwinding device 41 and a wire winding device 42. At least two cutting wires 32 are wound around the roller 3 at intervals corresponding to the wire winding and unwinding assemblies 4, and the winding directions of all the cutting wires 32 are the same. Each cutting wire 32 wound around the roller 3 forms a cutting sub-net 33, and the cutting sub-nets 33 are combined to form the cutting mesh surface 34 of the wire sawing machine. The wire unwinding device 41 and the wire winding device 42 are arranged on the cutting frame 2 corresponding to the two ends of the cutting wire 32, and one wire winding device 42 and one wire unwinding device 41 control the winding and unwinding of one cutting wire 32 respectively. The tensioning assembly 5 is arranged on the cutting frame 2 corresponding to the wire unwinding device 41 and the wire winding device 42, and can tension the cutting wire 32 wound around the roller 3.

[0054] The wire winding device 42 and the wire unwinding device 41 are respectively arranged at intervals on both sides of the cutting frame 2, and are arranged in an overall staggered manner on the cutting frame 2. The wire unwinding device 41 can adjust the length of the cutting wire 32 wound around the roller 3 by cooperating with the wire winding device 42 of another wire winding and unwinding assembly 4.

[0055] Compared with the first embodiment: A lifting multi-wire cutting wire saw provided in this embodiment has four sets of wire winding and unwinding assemblies 4 provided on the cutting frame 2, and can be applicable to cutting stones with more thickness specifications. For example, Figure 10 As shown, when each set of cutting wires 32 is connected to the corresponding wire winding and unwinding assembly 4, the length of the cutting wire 32 wound around the roller 3 is the smallest, and there is more cutting wire 32 reserved on the wire unwinding wheel 412, so that thicker materials can be cut during cutting; when the material to be cut is thinner, only a shorter reserved cutting wire 32 is needed to complete the cutting. Therefore, a longer cutting wire 32 can be wound around the roller 3. For example, Figure 10 As shown, the two ends of the first cutting wire 32 can be connected to the wire unwinding device 41 of the first wire winding and unwinding assembly 4 and the wire winding device 42 of the second wire winding and unwinding assembly, and the two ends of the second cutting wire 32 can be connected to the wire unwinding device 41 of the third wire winding and unwinding assembly 4 and the wire winding device 42 of the fourth wire winding and unwinding assembly 4, so that the second and fourth wire unwinding devices 41 and the first and third wire winding devices 42 do not need to work, reducing energy consumption; the length of the cutting wire 32 wound by the operator can be adjusted according to parameters such as the hardness and thickness of the material to be cut, so as to meet the cutting requirements of various materials.

[0056] It should be noted that if the number of the wire winding and unwinding assemblies 4 in the present application is N, then the composition types of the cutting mesh surface 34 are (the number of factors of N - 1). For example, when N = 6, the composition types of the cutting mesh surface 34 are (the factors of 6 are 1, 2, 3, 6, a total of 4, the number of factors of N - 1 = 4 - 1 = 3), which are respectively: ① One set of wire winding and unwinding assemblies forms a cutting subnet 33; ② 2 sets of wire winding and unwinding assemblies 4 form a cutting subnet 33 (a cutting wire 32 is respectively installed on the wire unwinding devices 41 of the first, third, and fifth sets of wire winding and unwinding assemblies 4 and the wire winding devices 42 of the second, fourth, and sixth sets of wire winding and unwinding assemblies 4 to form a cutting subnet 33, and 3 cutting subnets 33 form the cutting mesh surface 34); ③ 3 sets of wire winding and unwinding assemblies 4 form a cutting subnet 33 (a cutting wire 32 is respectively installed on the wire unwinding devices 41 of the first and fourth sets of wire winding and unwinding assemblies 4 and the wire winding devices 42 of the third and sixth sets of wire winding and unwinding assemblies to form a cutting subnet 33, and 2 cutting subnets 33 form the cutting mesh surface 34); thereby meeting the adjustment requirements for the length of the cutting wire 32 during cutting of different materials.

[0057] It should be noted that for the wire saw, the wire cutting assembly can be kept stationary, and the lifting frame 6 drives the cutting material to continuously rise. This method is usually called the jacking type wire saw (such as in Embodiment 1); it can also be the method that the lifting frame 6 remains stationary and the wire cutting assembly continuously moves downward. This method is usually called the pressing type wire saw.
