Description

Technical Field

[0001] This invention relates to the field of diamond wire cutting equipment technology, and in particular to a diamond wire cutting machine tool with a protective device. Background Technology

[0002] In the field of cutting and processing ores, tiles, geological materials, and adhesive composite materials, diamond wire cutting machines are commonly used processing equipment. The core processing principle is as follows: using a ring-shaped diamond wire as a cutting tool, the ring-shaped diamond wire is tensioned and driven by a guide wheel. Under the drive of the guide wheel, the diamond ring-shaped wire achieves high-speed cyclic motion. At the same time, with the help of a lifting mechanism, the diamond ring-shaped wire is driven to move towards the preset cutting position of the workpiece. The material removal is completed through the mechanical grinding action of the diamond abrasive grains.

[0003] However, the overall protective performance of current diamond wire cutting machines is at a low level, revealing numerous technical shortcomings in practical applications and severely impacting processing efficiency, product quality, and operational safety. Specifically, existing equipment lacks effective wire breakage detection and protection mechanisms, making it difficult to monitor the working status of the diamond wire in real time. When wire breaks or slips, manual intervention and machine shutdown are required. This not only degrades workpiece cutting quality but also risks equipment damage and personnel safety due to the high-speed ejection of broken wire. This is a direct manifestation of inadequate protective performance in terms of safety monitoring and protection.

[0004] Meanwhile, cutting bonded composite materials generates a large amount of highly adhesive cutting debris, which readily adheres to the surface of the diamond toroidal rings. On one hand, this debris covers the diamond abrasive grains on the toroidal ring surface, reducing cutting sharpness and significantly decreasing cutting efficiency. On the other hand, the adhered debris reduces the friction between the diamond toroidal ring and the guide wheel, leading to toroidal slippage. Existing equipment lacks the ability to detect this slippage in real time, ultimately causing further deterioration in workpiece cutting quality. The root cause of these problems lies in the lack of effective cleaning, protection, and condition monitoring measures for the toroidal rings, representing a deficiency stemming from insufficient protective performance.

[0005] Furthermore, the existing equipment's tension adjustment methods are cumbersome and lack intuitiveness and precision. The tension of the diamond wire loop directly determines the cutting stability, requiring operators to indirectly judge the tension through complex calculations, which can easily lead to over- or under-tensioning due to calculation errors. Excessive tension accelerates the fatigue and aging of the loop, increasing the risk of breakage; insufficient tension causes loop vibration and slippage, also severely impacting cutting quality. This design, lacking precise control and real-time feedback, essentially reflects inadequate protection of the loop during operation, further confirming the core problem of the existing equipment's poor protective performance. It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

The semi-enclosed first protective cover effectively prevents broken diamond toroidal wire from being thrown out, ensuring the safety of operators and preventing damage to the machine tool's core components. The cleaning mechanism continuously rinses and cools the diamond toroidal wire during cutting, quickly removing adhering chips and preventing chip accumulation that could cause slippage between the toroidal wire and the wheel, thus optimizing the working conditions of the diamond toroidal wire. The wire breakage detection component monitors the driven wheel speed in real time and compares it with the driving wheel speed. If an abnormal speed deviation occurs, it quickly triggers an emergency stop and alarm, forming a complete monitoring and protection closed loop to prevent further escalation of the fault. The tension adjustment component precisely controls the tension of the diamond toroidal wire, reducing the risk of toroidal wire malfunctions from the source. The various protective components work in concert with the machine tool actuators to significantly improve the reliability and continuity of equipment operation while ensuring cutting efficiency and precision, extend the service life of the machine tool and diamond wire, and comprehensively enhance the safety assurance capability of cutting operations.

Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0022] Please see Figures 1 to 10 As shown, this invention provides a diamond wire cutting machine tool with a protective device, including a bed 1, a translation mechanism 2, a worktable 3, a lifting mechanism 4, a cutting mechanism 5, a cleaning mechanism 6, a first protective cover 7, and a wire breakage detection component 8. The bed 1 includes a base 11 and a column 12 fixed on the base 11; the translation mechanism 2 is mounted on the base 11, and its output end is provided with a horizontal slide 21 for driving the horizontal slide 21 to translate along the Y direction; the worktable 3 is mounted on the horizontal slide 21 for fixing the workpiece; the lifting mechanism 4 is mounted on the column 12, and its output end is provided with a vertical slide 41 for driving the vertical slide 41 to rise and fall along the Z direction; the cutting mechanism 5 is mounted on the vertical slide 41, and the cutting mechanism 5 includes a driving wheel 51, two driven wheels 52, a tensioning wheel 53, a tension adjustment component 54, and a drive rotation component 55; the driving wheel 51 and the two driven wheels 52 are rotatably connected to the vertical slide 41, and the drive rotation component... A tension adjustment assembly 55 is mounted on a vertical slide table 41, with its output end connected to the drive wheel 51 to drive its rotation. A tension adjustment assembly 54 is mounted on the vertical slide table 41, with its output end connected to the tension wheel 53. A diamond ring 56 is wound around the outer circumference of the tension wheel 53, the drive wheel 51, and the two driven wheels 52. The tension adjustment assembly 54 is used to adjust the tension of the diamond ring 56, which rotates with the drive wheel 51, the two driven wheels 52, and the tension wheel 53. During cyclic motion, the workpiece can be cut; the cleaning mechanism 6 is located on the vertical slide 41 and is used to rinse and cool the moving diamond toroidal wire 56; the first protective cover 7 is installed on the vertical slide 41, has a semi-enclosed structure and covers the outer periphery of the driving wheel 51, the tensioning wheel 53 and the two driven wheels 52, and is used to protect the diamond toroidal wire 56 and each wheel body; the wire breakage detection component 8 is located on the vertical slide 41 and is used to detect the rotational speed of one of the driven wheels 52.

[0023] During the cutting process, the workpiece to be cut is fixed on the worktable 3, and the position of the tensioning wheel 53 is adjusted by the tensioning adjustment component 54 to ensure that the diamond ring wire 56 reaches the preset tension, ensuring that the ring wire does not slip or loosen during the cutting process. Next, the translation mechanism 2 drives the horizontal slide table 21 to move along the Y direction, moving the worktable 3 and the workpiece to the cutting position. Then, the lifting mechanism 4 drives the vertical slide table 41 to descend along the Z direction, aligning the diamond ring wire 56 with the cutting path of the workpiece. Subsequently, the drive rotation component 55 drives the drive wheel 51 to rotate, and the diamond ring wire 56 circulates at high speed under the coordinated action of the drive wheel 51, the driven wheel 52 and the tensioning wheel 53. At the same time, the lifting mechanism 4 cooperates with the feed, so that the diamond ring wire 56 gradually cuts into the workpiece, completing the cutting operation. During the cutting process, the cleaning mechanism 6 continuously rinses and cools the diamond ring wire 56 and removes debris. The wire breakage detection component 8 continuously monitors the rotation speed of the driven wheel 52. The machine tool control system compares the rotation speed of the driven wheel 52 with that of the driving wheel 51. If the speed difference between the two exceeds a preset threshold, it is determined that the diamond ring wire 56 has broken or slipped. At this time, the control system immediately triggers an emergency stop and issues an alarm signal.

[0024] Through the above-mentioned settings, the protective performance of the equipment can be improved in three aspects: structural protection, cleaning protection, and monitoring protection. Among them, the first protective cover 7 uses physical isolation to prevent the diamond toroidal wire 56 from being directly thrown out after a breakage, achieving basic protection for operators and core machine tool components; the cleaning mechanism 6 continuously washes the diamond toroidal wire 56, which not only quickly removes the cutting debris adhering to the toroidal wire, avoiding slippage between the toroidal wire and the wheel caused by debris accumulation, but also reduces the working temperature of the diamond toroidal wire 56, reducing the attenuation of the toroidal wire strength caused by high temperature, thus improving the reliability of protection from the perspective of optimizing working conditions; the wire breakage detection component 8 monitors the rotation speed of the driven wheel 52 in real time, which can instantly detect abnormal rotation speed caused by wire breakage or slippage, quickly feed back to the control system and trigger a stop command, forming a complete monitoring and protection closed loop; at the same time, the tension adjustment component 54 can accurately control the tension of the diamond toroidal wire 56, reducing the risk of wire breakage and vibration caused by tension inaccuracy from the source. The aforementioned protective components work together to effectively prevent safety accidents and processing failures caused by problems such as wire breakage, slippage, debris accumulation, and tension inaccuracy. While ensuring cutting efficiency and processing accuracy, they also improve the reliability, continuity of operation, and service life of the equipment.

[0025] In a preferred embodiment, see [reference] Figure 2 , 3The cleaning mechanism 6 includes a support 61, at least two nozzles 62, at least one brush 63, and a second protective cover 64. The support 61 is mounted on a vertical slide 41, and the nozzles 62 and brushes 63 are both mounted on the support 61 and arranged at intervals along the movement direction of the diamond ring 56. Each nozzle 62 is externally connected to a coolant spray system 10. The nozzles 62 and brushes 63 form a progressive cleaning structure. The nozzles 62 at the front end face the diamond ring 56 and spray high-pressure coolant through the external coolant spray system 10, first cleaning the ring. Most of the cutting debris adhering to the surface is pre-rinsed to initially clean the impurities on the surface of the diamond ring. Then, the diamond ring 56 is brushed by the brush 63 to remove stubborn debris and residual impurities, and to prevent impurities from embedding into the gaps between the diamond abrasive grains. The nozzle 62 at the rear end sprays coolant again to perform a secondary rinse on the brushed ring, to wash away the debris that was brushed off in time, and to further cool the ring, ensuring that the ring is in the best working state of cleanliness and low temperature when it enters the cutting area.

[0026] The second protective cover 64 is mounted on the bracket 61 and has a closed structure, used to cover all the nozzles 62 and brushes 63 inside it. The second protective cover 64 has a clearance groove 641 for the diamond ring wire 56 to pass through. The second protective cover 64 can effectively block the splashing of high-pressure coolant during the cleaning process, preventing the cleaning fluid from contaminating other parts of the equipment or affecting the operating environment. Preferably, both the nozzle 62 and the brush 63 are vertically arranged and located below the lower horizontal section of the diamond ring 56, so that the cleaned diamond ring 56 can directly enter the cutting operation area, effectively preventing the surface of the diamond ring 56 from being contaminated with new impurities again after cleaning. Each nozzle 62 sprays from bottom to top. After the high-pressure coolant sprays upward to impact the surface of the diamond ring 56, it bounces back and falls back under the blocking effect of the second protective cover 64, forming a secondary impact cleaning effect, further improving the chip removal efficiency. Finally, the coolant flows out of the protective cover through the connection gap between the second protective cover 64 and the bracket 61 and the clearance groove 641, and flows downward to the base 11 for discharge, ensuring that the cleaning waste liquid is collected in an orderly manner.

[0027] As described above, the clearance groove 641 extends in a direction away from the support 61 on the horizontal plane, forming an open clearance structure. When installing or removing the diamond ring wire 56, it can be pulled out or pushed in horizontally along the Y direction from the clearance groove 641, which simplifies the replacement process of the diamond ring wire 56 and improves the equipment maintenance efficiency.

[0028] In this embodiment, two nozzles 62 are provided, and one brush 63 is provided, with the brush 63 located between the two nozzles 62. The nozzle 62 at the front end has a conical outlet, enabling the coolant to form a concentrated, high-pressure jet that accurately sprays the diamond ring 56 surface with significant impact force, quickly removing most of the attached cutting debris. The nozzle 62 at the rear end has a fan-shaped outlet, allowing the coolant to evenly spray the diamond ring 56 surface over a wider coverage area, thoroughly washing away any residual debris removed by the brush 63, while simultaneously achieving uniform cooling of the ring surface.

[0029] In a preferred embodiment, see [reference] Figure 5 The drive rotation assembly 55 includes a first drive motor 551, a synchronous belt drive assembly 552, a first rotating shaft 553, a third protective cover 554, and a fourth protective cover 555. The first drive motor 551 is mounted on a vertical slide table 41, and the first rotating shaft 553 is rotatably connected to the vertical slide table 41. One end of the first rotating shaft 553 is coaxially fixedly connected to the drive wheel 51, and the other end is driven by the synchronous belt drive assembly 552 to the output shaft of the first drive motor 551. The power output from the first drive motor 551 is transmitted to the first rotating shaft 553 via the synchronous belt drive assembly 552. The first rotating shaft 553 rotates smoothly, thereby driving the drive wheel 51 to rotate coaxially, providing a stable and reliable power source for the cyclic cutting of the diamond toroidal wire 56. The use of synchronous belt drive not only increases the linear speed but also reduces the motion error of the first rotating shaft 553, avoiding disturbance to the highly rotating diamond toroidal wire 56 and ensuring smooth and precise cutting motion.

[0030] The first rotating shaft 553 preferably adopts a direct-drive spindle. The direct-drive spindle has superior precision and dynamic and static stiffness, low vibration and low noise, which can significantly reduce the running runout of the drive wheel 51 and effectively avoid problems such as deviation and vibration of the diamond toroidal cable 56 caused by spindle shaking.

[0031] To optimize the spatial layout and reduce the installation space occupied by the drive rotation assembly 55, the synchronous belt drive assembly 552 is arranged in the rear area of ​​the vertical slide 41, and the first drive motor 551 extends forward and is located on the same side as the drive wheel 51. A third protective cover 554 is provided on the vertical slide 41 to cover the first drive motor 551, and a fourth protective cover 555 is provided on the vertical slide 41 to cover the synchronous belt drive assembly 552. The third protective cover 554 and the fourth protective cover 555 work together to form a complete closed protective structure, which can effectively prevent cutting chips and coolant from entering the interior, avoid the drive components from rusting, jamming or being damaged due to contamination, and ensure the stable operation of the drive rotation assembly 55.

[0032] In a preferred embodiment, see [reference] Figure 7The tension adjustment assembly 54 includes a mounting base 541, two first guide rails 542, a first slide plate 543, a second slide plate 544, and a drive translation assembly 545. The mounting base 541 is fixed on the vertical slide table 41. The first guide rails 542 are arranged along the X direction. The first slide plate 543 and the second slide plate 544 are slidably connected to the two first guide rails 542. The tension wheel 53 is rotatably connected to the first slide plate 543. A tension sensor 546 is provided between the first slide plate 543 and the second slide plate 544. The drive translation assembly 545 is located on the mounting base 541, and its output end is connected to the second slide plate 544 to drive the second slide plate 544 to slide along the first guide rails 542. When installing or removing the diamond toroidal wire 56, the drive translation component 545 moves the second slide plate 544 towards the center of the diamond toroidal wire 56. The second slide plate 544, through the tension sensor 546, pushes the first slide plate 543 and the tension wheel 53 to move synchronously, causing the tension wheel 53 to move closer to the driven wheel 52. At this time, the diamond toroidal wire 56 is in a relaxed state, allowing for easy removal of the old toroidal wire and replacement with a new one. When adjusting the tension of the diamond toroidal wire 56, the drive translation component 545 reverses the drive, and the second slide plate 544, through the tension sensor 546, pulls the first slide plate 543 and the tension wheel 53 away from the driven wheel 52, gradually tightening the diamond toroidal wire 56. During this process, the tension sensor 546 provides real-time feedback on the tension value, achieving closed-loop precise control of the tension. When the tension reaches the preset threshold, the adjustment is complete, ensuring that each tension adjustment strictly matches the processing requirements.

[0033] Because the first slide plate 543 and the second slide plate 544, which are connected by the tension sensor 546, form a rigid direct connection structure, the tension of the diamond ring wire 56 borne by the tension wheel 53 can be directly transmitted to the tension sensor 546 without loss or lag. This effectively eliminates the detection error caused by gap connection and significantly improves the accuracy and response speed of tension acquisition. At the same time, the first slide plate 543 and the second slide plate 544 share two first guide rails 542 to achieve synchronous sliding, which can ensure that their movement trajectories are coaxial and their directions of travel are consistent. This avoids tension detection distortion caused by relative sway or misalignment, making the real-time monitoring and closed-loop control of tension more stable and reliable, and further meeting the stringent control requirements of high-precision cutting and processing for the tension of the diamond ring wire 56.

[0034] The aforementioned drive translation component 545 can be implemented in various forms to adapt to different operational requirements. In this embodiment, such as... Figure 7As shown, the drive translation component 545 includes a first lead screw and nut pair and a handwheel. The nut of the first lead screw and nut pair is fixedly connected to the second slide plate 544, and the handwheel is connected to the lead screw of the first lead screw and nut pair. The second slide plate 544 can be driven to move by manually rotating the handwheel. The operation is simple and easy, and the tension adjustment feedback is intuitive and clear, facilitating the quick assembly and disassembly and on-site debugging of the diamond toroidal wire 56. In addition, this component can also use a servo motor to replace the handwheel and connect to the lead screw of the first lead screw and nut pair. Combined with the real-time tension signal feedback from the tension sensor 546, an automatic closed-loop control system can be formed. It can automatically and accurately adjust the tension force according to the cutting process parameters, ensuring the consistency and high precision of tension control, and meeting the production needs of automated continuous cutting, effectively improving the processing efficiency and automation level of the equipment.

[0035] In other alternative embodiments, the drive translation component 545 may also be any one of an electric push rod, a pneumatic hydraulic cylinder, or a hydraulic cylinder. The telescopic end of the electric push rod, the piston rod of the pneumatic cylinder, or the hydraulic cylinder is fixedly connected to the second slide plate 544. Its linear telescopic motion can be directly converted into the directional displacement of the second slide plate 544, which has the advantages of rapid response and controllable thrust output. It can also reliably adjust the tension of the diamond toroidal wire 56.

[0036] Further, see Figure 7 The first slide plate 543 and the second slide plate 544 are respectively provided with a first bellows cover 547 between them and the mounting base 541. The two first bellows covers 547 can expand and contract synchronously with the sliding of the first slide plate 543 and the second slide plate 544, and can fully cover the internal moving parts of the first guide rail 542 and the tension adjustment component 54, effectively preventing cutting chips, dust and cleaning coolant from entering the guide rail pair, and avoiding the accumulation of foreign objects that cause sliding jamming and component wear.

[0037] The first slide plate 543 is provided with a fifth protective cover 548. The two ends of the fifth protective cover 548 extend to the outside of the two first bellows covers 547 respectively. The protective cover is a sheet metal bending forming part, which can cover the gap between the first slide plate 543 and the second slide plate 544 as well as the gap between each slide plate and the mounting base 541, and at the same time protect the tension sensor 546. Furthermore, the fifth protective cover 548 does not directly contact the first bellows cover 547 and the second slide plate 544, which can avoid interference problems caused by rigid connection and prevent interference with the tension measurement. While achieving all-round sealing protection, it ensures the accuracy and reliability of tension detection.

[0038] To further enhance the protection of the tension adjustment assembly 54 and reduce the intrusion of coolant into the tension adjustment assembly 54, a protective sleeve 5481 is provided on the fifth protective cover 548. The protective sleeve 5481 is sleeved on the outer circumference of the shaft of the tension wheel 53, and its end is close to the end face of the tension wheel 53, forming a closed protective structure around the shaft.

[0039] In a preferred embodiment, see [reference] Figure 6 The wire breakage detection component 8 includes a marker block 81 and a proximity switch 82. One of the driven wheels 52 is equipped with a mounting plate 83 coaxially arranged with it. The marker block 81 is located on the peripheral wall of the mounting plate 83, and the proximity switch 82 is located on a vertical slide table 41. When the marker block 81 rotates with the driven wheel 52, the proximity switch 82 detects the position of the marker block 81. During the rotation of the driven wheel 52, the marker block 81 rotates synchronously with the mounting plate 83. Each time it passes through the sensing area of ​​the proximity switch 82, a pulse signal is triggered. The number of pulse signals per unit time directly reflects the rotational speed of the driven wheel 52, thereby achieving real-time monitoring of the operating status of the driven wheel 52.

[0040] Specifically, the driven wheel 52 is fixedly connected to a second rotating shaft 521 and rotatably connected to the vertical slide table 41. The mounting plate 83 is coaxially fixedly connected to the end of the second rotating shaft 521 and can rotate synchronously with the driven wheel 52. Preferably, the second rotating shaft 521 is a direct-drive spindle to ensure accurate power transmission.

[0041] During machine tool operation, the machine tool control system compares the rotational speeds of the drive wheel 51 and the driven wheel 52 in real time: when the diamond ring wire 56 is under normal tension and cutting conditions, the driven wheel 52 rotates synchronously at high speed with the drive wheel 51 under the drive of the ring wire, and the two speeds are matched; if the diamond ring wire 56 breaks or slips, the rotational speed of the driven wheel 52 will decrease significantly, and the pulse frequency detected by the proximity switch 82 will decrease accordingly. When the difference between the rotational speed of the drive wheel 51 and the rotational speed of the driven wheel 52 is less than 10 r / min, the system determines that the diamond ring wire 56 has broken or slipped abnormally, and immediately triggers a stop alarm command to avoid workpiece cutting defects or equipment damage caused by the failure of the diamond ring wire 56. Meanwhile, the first protective cover 7 can effectively contain the diamond ring wire 56 that splashes at high speed after the wire breaks, preventing the swinging ring wire from hitting surrounding equipment components; the second protective cover 64, which is adjacent to the workpiece cutting area, can physically isolate the cleaning components, and its sidewalls can effectively block the ring wire that bounces abnormally in this area after the wire breaks, avoiding the ring wire impact damage to cleaning components such as nozzle 62 and brush 63. The two, together with the instant stop control function of the wire breakage detection component 8, comprehensively improve the safety of equipment operation and fault handling.

[0042] It should be noted that the peripheral walls of the driving wheel 51, driven wheel 52 and tensioning wheel 53 are provided with V-shaped grooves, and the diamond ring wire 56 is wound in the V-shaped grooves of each wheel body; the V-shaped grooves play a limiting role for the diamond ring wire 56, effectively preventing the diamond ring wire 56 from running off course or detaching from the wheel during high-speed cyclic operation.

[0043] In a preferred embodiment, see [reference] Figure 2 ,10 It also includes a filter mechanism 9. The base 11 has a downwardly recessed liquid collection tank 111, and a boss 112 is provided on the liquid collection tank 111. The translation mechanism 2 is located on the boss 112. The base 11 has a drain hole 113, one end of which is connected to the liquid collection tank 111. By providing the boss 112, it is possible to prevent coolant from accumulating to a certain height and seeping into the translation component. This prevents coolant from invading the translation mechanism 2 and causing problems such as corrosion and jamming of the transmission components. The bottom of the liquid collection tank 111 is inclined towards the drain hole 113, which allows the waste liquid to flow quickly to the drain hole 113 by gravity, improving the coolant discharge efficiency.

[0044] The filtration mechanism 9 includes a drain pipe 91, a filter box 92, and a water pump 93. The filter box 92 is provided with at least two filter chambers 921 arranged sequentially along the flow direction of the coolant. A first filter assembly 922 is provided between two adjacent filter chambers 921. A second filter assembly 923 is provided at the inlet of the first filter chamber 921. One end of the drain pipe 91 is connected to the drain hole 113, and the other end of the drain pipe 91 extends into the second filter assembly 923. A water outlet pipe 94 is connected to the filter chamber 921 at the end. The water pump 93 is connected in series to the water outlet pipe 94. The water outlet pipe 94 is connected to the water inlet of the coolant spray system 10. During cutting operations, the debris generated during cutting and cleaning falls into the collection tank 111 of the base 11 along with the coolant. It then flows along the inclined bottom of the tank to the drain hole 113 and is transported to the filter box 92 via the drain pipe 91. The coolant first undergoes coarse filtration through the second filter assembly 923 to remove larger cutting debris. It then flows sequentially through various filter chambers 921, where internal filters achieve multi-stage fine filtration, gradually removing fine impurities and dust, thus completing the coolant purification process. The purified coolant, driven by the pressure of the water pump 93, is then transported back to the coolant spray system 10 via the outlet pipe 94, achieving a closed-loop recycling of the coolant. By setting up a multi-stage progressive filtration structure, various cutting impurities in the coolant can be thoroughly removed, effectively preventing clogging of the coolant spray system 10. Furthermore, the recycling of the coolant not only significantly reduces production consumable costs but also reduces wastewater discharge.

[0045] Preferably, see Figure 10The second filter assembly 923 includes a filter basket 9231 and a first filter screen 9232. The top of the filter basket 9231 has flanges around its perimeter, which rest on the top of the first-end filter chamber 921. With a handle, the filter basket 9231 can be quickly lifted for easy periodic cleaning of trapped impurities. The first filter screen 9232 is located at the bottom of the filter basket 9231 and effectively intercepts large-particle cutting impurities in the coolant, achieving primary coarse filtration. The first filter assembly 922 uses two perforated plates 9221 to clamp the second filter screen 9222, forming a detachable filter element unit. The pore size of the second filter screen 9222 is smaller than that of the first filter screen 9232, allowing for precise interception of fine suspended impurities in the coolant. Furthermore, along the coolant flow direction, the pore size of each stage of the second filter screen 9222 gradually decreases, forming a gradient fine filtration that ensures that impurities of different particle sizes are efficiently intercepted, significantly improving the coolant purification effect.

[0046] It should be noted that coolant must be continuously sprayed onto the cutting area throughout the entire cutting process. The coolant spraying system 10 sprays coolant directionally onto the workpiece's processing area through matching spray pipes, ensuring that the contact area between the diamond ring wire 56 and the workpiece remains at a low temperature. This effectively suppresses thermal deformation caused by cutting heat between the workpiece and the ring wire, and reduces frictional wear on the diamond ring wire 56. Combined with the circulating filtration and reuse of coolant, this ensures the accuracy and stability of the cutting process. The spray pipes are not shown in the attached diagram.

[0047] In a preferred embodiment, see [reference] Figure 3 , 4 The lifting mechanism 4 includes two second guide rails 42, a connecting plate 43, a driving lifting assembly 44, and two sets of pulley groups 45. The two second guide rails 42 are mounted on the column 12, and the connecting plate 43 is slidably engaged with the second guide rails 42. A vertical slide 41 is mounted on the connecting plate 43. The driving lifting assembly 44 is mounted on the column 12, and its output end is connected to the connecting plate 43. The two sets of pulley groups 45 are symmetrically arranged on the top of the column 12. Each set of pulley groups 45 is wound with a steel wire rope 46. One end of the two steel wire ropes 46 is fixedly connected to the top of the connecting plate 43, and the other end is connected to a counterweight block 47 that is vertically slidably engaged with the column 12.

[0048] During operation, the drive lifting assembly 44 drives the connecting plate 43 to make vertical linear displacement along the second guide rail 42, thereby driving the vertical slide 41 and the overall cutting execution mechanism to rise and fall synchronously. The cutting height can be flexibly adjusted to meet the processing needs of workpieces of different sizes and specifications. Two sets of symmetrically arranged pulley groups 45 and counterweight blocks 47 form a balanced counterweight structure through steel wire ropes 46 to balance the overall center of gravity of the machine tool on the lifting side, effectively offsetting the off-center load of the self-weight of moving parts such as the vertical slide 41 and the cutting mechanism 5, so that the center of gravity of the entire machine tool always remains stable.

[0049] Further, see Figure 3 , 4 The lifting mechanism 4 further includes a first baffle 48, a second baffle 49, and a second bellows cover 410. Two first baffles 48 are symmetrically arranged on the column 12 and extend along the Z-direction. The top and bottom of the connecting plate 43 are connected to the column 12 via the second bellows cover 410. Each second bellows cover 410 forms a labyrinthine first gap 481 between its two sides and the two first baffles 48, thus creating a waterproof structure. Two second baffles 49 are symmetrically arranged on both sides of the connecting plate 43. The two ends of each second baffle 49 extend to the two second bellows covers 410 and are sealed to them. The second baffles 49 are located outside the first baffles 48. Through the above configuration, the first baffle 48, the second baffle 49, the labyrinthine first gap 481, and the second bellows cover 410 work together to form a fully enclosed protective system: the labyrinthine first gap 481 can significantly extend the path of contaminant intrusion, effectively blocking the coolant, dust, and debris splashed from cutting from entering the second guide rail 42 and the interior of the lifting transmission pair; the sealed connection between the second baffle 49 and the second bellows cover 410 can prevent impurities from entering the interior of the lifting mechanism 4 through the gap between the connecting plate 43 and the column 12, while this structure will not interfere with the normal lifting and sliding of the connecting plate 43 along the Z direction, thus balancing protective performance and movement flexibility.

[0050] As described above, the drive lifting assembly 44 includes a second drive motor 441 and a second lead screw and nut pair 442. The nut of the second lead screw and nut pair 442 is fixedly connected to the connecting plate 43. The second drive motor 441 drives the lead screw of the second lead screw and nut pair 442 to rotate through a coupling, thereby controlling the lifting displacement of the connecting plate 43 to complete the cutting and slitting workpiece.

[0051] In a preferred embodiment, see [reference] Figure 8 , 9 The translation mechanism 2 further includes a third accordion cover 22, a fourth accordion cover 23, and a fourth baffle 24; the boss 112 is provided with two symmetrically arranged third baffles 25 extending along the Y direction; the side of the horizontal slide 21 near the column 12 is connected to the column 12 through the third accordion cover 22, and the side of the horizontal slide 21 away from the column 12 is connected to the end of the boss 112 through the fourth accordion cover 23. Both sides of the third accordion cover 22 and the fourth accordion cover 23 form a labyrinthine second gap 251 between them and the two third baffles 25; the two fourth baffles 24 are symmetrically arranged on both sides of the horizontal slide 21, and the two ends of the fourth baffles 24 extend to the third accordion cover 22 and the fourth accordion cover 23 respectively and are sealed and fitted with them, and the fourth baffles 24 are located outside the third baffles 25.

[0052] Specifically, see Figure 8The column 12 adopts a portal structure design, and a baffle plate 121 is provided in the middle of the column 12. Part of the structure of the translation mechanism 2 extends through the baffle plate 121 to the rear of the column 12, which not only optimizes the overall structure layout of the machine, but also achieves the design goal of reducing the weight of the machine tool. One end of the third bellows cover 22 is connected to the horizontal slide 21, and the other end is sealed to the baffle plate 121, which, together with the fourth bellows cover 23, forms full-stroke protection for the translation mechanism 2.

[0053] Through the above configuration, the third stop bar 25, the fourth stop bar 24, the labyrinth-type second gap 251, the third bellows cover 22, and the fourth bellows cover 23 work together to form a fully enclosed protective system. The labyrinth-type second gap 251 can effectively extend the path of contaminant intrusion and block the coolant, dust, and debris splashed during the cutting process from entering the guide rail pair and transmission components of the translation mechanism 2. The sealed connection between the fourth stop bar 24 and the bellows cover prevents impurities from entering the translation mechanism 2 through the gap between the horizontal slide table 21 and the boss 112. Moreover, the entire protective structure will not interfere with the normal translation movement of the horizontal slide table 21 along the Y direction, ensuring the translation feed accuracy and operational stability.

[0054] See above. Figure 9 The translation mechanism 2 includes a third drive motor 26 and a third lead screw and nut pair 27. The nut of the third lead screw and nut pair 27 is fixedly connected to the horizontal slide table 21. The third drive motor 26 drives the lead screw of the third lead screw and nut pair 27 to rotate through a coupling, thereby precisely controlling the translational displacement of the horizontal slide table 21 along the Y direction, so as to complete the preset cutting thickness and feed positioning.

[0055] See above. Figure 8 The worktable 3 includes a turntable 31 mounted on a horizontal slide 21 and a worktable surface 32 fixed on the turntable 31. The workpiece is fixed on the worktable surface 32. The turntable 31 is a high-precision CNC turntable, which can drive the workpiece to rotate 360° around the Z-axis. It can flexibly adjust the angle according to the cutting orientation requirements of the workpiece.
