Description

Technical Field

[0001] The present invention belongs to the technical field of casting cutting, and particularly relates to a stainless steel casting cutting device and a cutting process. Background Art

[0002] A stainless steel casting cutting device is a mechanical equipment specifically used for cutting stainless steel castings. Its core objective is to achieve precise separation of the casting material through physical or thermal effects to meet the requirements of casting size, shape, and precision in industrial production.

[0003] In the prior art during the cutting process, a coolant is often used to cool the cutting tool and the cutting end of the steel pipe. When screening debris and coolant, a cuboid filter plate is often used to screen debris and coolant. However, the debris will fall at any position on the filter plate, which not only easily blocks some of the slots, resulting in the subsequent coolant not being able to uniformly drop out from the slots, but also forms residues on the surface of the filter plate, affecting the screening efficiency, making the coolant recovery effect poor, increasing production costs, and also increasing the workload of cleaning the debris and coolant residues subsequently.

[0004] Therefore, the present invention provides a stainless steel casting cutting device and a cutting process. Summary of the Invention

[0009] Preferably, the sliding assembly includes two iron blocks. The two iron blocks are respectively fixedly connected to the other sides of the fixed plates. A through electromagnet is fixedly installed on the top of the cutting table. The through electromagnet is located on one side of the iron blocks. A first spring is arranged outside the fixed rod. The two ends of the first spring are respectively fixedly connected to one side of the movable block and one side of the power plate. The rigidity strength of the first spring is much greater than that of the torsion spring.

[0010] Preferably, the counterweight assembly includes multiple first hinged seats. The multiple first hinged seats are respectively fixedly connected to the bottoms of the two filter plates one. Cables are hinged to the inner walls of the first hinged seats. Conical counterweight blocks are fixedly connected to the bottoms of the cables.

[0011] Preferably, convex blocks are symmetrically fixedly connected to the outer walls of the circular blocks. A rotating assembly is arranged on one side of the circular block. The rotating assembly enables the circular block to rotate during the entire cutting process.

[0012] Preferably, the rotating assembly includes multiple rack plates. The multiple rack plates are respectively fixedly connected to one sides of the two power plates. The teeth of the multiple rack plates are all meshed with gears. The gears are fixedly connected to one ends of the shaft rods of the circular blocks.

[0013] Preferably, a collection box and a collection tray are provided below the first filter plate. The collection box is directly below the bottom surface of the first filter plate, and the collection tray is located below the side of the top of the first filter plate. Both the collection box and the collection tray are located on the top of the cutting table. One end of the collection box is fixedly connected and communicated with a connecting pipe. A second water pump is provided outside the connecting pipe. The end of the connecting pipe away from the collection box is fixedly connected and communicated with the cold liquid tank.

[0014] A stainless steel casting cutting device, and now a cutting process applicable to this device is proposed: S1. Start the hydraulic cylinder to drive the protective shell and the cutting tool to descend. At the same time, start the motor to make the cutting tool rotate through the transmission structure for cutting. The first water pump sprays the coolant in the cold liquid tank to the cutting area through the spray pipe for cooling. The mixture of debris and coolant falls onto the screening assembly; S2. The mixture of debris and coolant slides down along the first V-shaped filter plate and the second filter plate. Most of the coolant falls into the collection box through the slot holes, and the debris is concentrated at the bottom of the V-shaped inner wall; S3. After cutting is completed, the protective shell and the cutting tool rise, driving the power plate to rise, and then lifting the support plate by the hinge rod. The support plate drives the first filter plate to rise. Under the action of the counterweight assembly, the first filter plate forms a slag discharging posture.

[0015] S4. The debris and the remaining coolant slide down along the inclined surface of the first filter plate again. Part of the coolant falls into the collection box through the slot holes; S5. After rising to a certain height, the electromagnet is energized, and the movable block drives the fixed plate and the hinge rod to move horizontally. The top of the hinge rod is disengaged from the bottom surface of the support plate; S6. The support plate descends and resets under the action of the second spring, and the first filter plate returns to the W-shaped state; S7. The coolant in the collection box is returned to the cold liquid tank through the connecting pipe and the second water pump, and the debris falls into the collection tray.

[0016] A stainless steel casting cutting process. The lifting assembly and the sliding assembly specifically include the following steps: M1. Drive the power plate to move by the rising and falling of the protective shell, and then drive the hinge rod to move. After cutting is completed, the top of the hinge rod will lift the bottom surface of the support plate to rise together, so that the support plate rises, driving the first filter plate and the second filter plate to move. The first filter plate rotates in a hinged manner with the shaft rod as the axis, gradually forming a slag discharging posture that slopes downward obliquely. The debris concentrated at the bottom of the V-shaped inner wall will slide out from both sides along the inclined surface of the first filter plate under the action of gravity; When the iron block enters the suction range of the energized electromagnet, the movable block slides laterally along the outer wall of the fixed rod and compresses the first spring. At this time, the movable block drives the fixed plate and the hinge rod to move laterally synchronously, so that the top of the hinge rod is disengaged from the bottom surface of the support plate. After the iron block rises to its original position, the energized electromagnet is powered off, and the movable block moves laterally in the reverse direction under the action of the first spring to reset, preparing for the next cutting and lifting.

[0017] The beneficial effects of the present invention are as follows: 1. For the stainless steel casting cutting device and cutting process of the present invention, through the screening assembly, the chips and coolant generated during the cutting process are effectively separated, so that the coolant can be quickly recovered into the internal cold liquid tank for continued use, reducing the waste of coolant and lowering the production cost.

[0018] 2. For the stainless steel casting cutting device and cutting process of the present invention, the first filter plate and the second filter plate are in a V shape. When the mixture of chips and coolant falls above it, it will slide along the inclined surface to the intersection (i.e., the bottom of the V-shaped inner wall), forming a concentrated accumulation area, preventing the chips from blocking some of the slots, resulting in the subsequent coolant being unable to uniformly fall out of the slots and forming residues on the filter plate surface, improving the screening efficiency. After the cutting is completed, the first filter plate rotates hingedly around the shaft rod of the hinge, gradually forming a slag discharge posture inclined downward. The chips concentrated at the bottom of the V-shaped inner wall will slide out from both sides along the inclined surface of the first filter plate under the action of gravity, facilitating the centralized treatment of the chips.

[0019] 3. For the stainless steel casting cutting device and cutting process of the present invention, the lifting assembly drives the power plate to move through the up and down movement of the protective shell, and then drives the hinge rod to move. After the cutting is completed, the top of the hinge rod will lift the bottom surface of the support plate and rise together, so that the support plate rises, driving the first filter plate and the second filter plate to move, realizing the effect of discharging chips and secondarily screening the coolant, without manual intervention, improving the automation degree and working efficiency of the device.

[0020] 4. For the stainless steel casting cutting device and cutting process of the present invention, through the lateral detachment mechanism of the sliding assembly, the support plate automatically resets after the slag discharge is completed, forming a complement to the upward drive of the lifting assembly to ensure the integrity of the process cycle.

[0021] 5. For the stainless steel casting cutting device and cutting process described in the present invention, through the rotation assembly, a slight vibration effect is produced by the up and down movement of the first filter plate, enabling the debris and coolant to slide better along the inclined surfaces of the first filter plate and the second filter plate for screening and centralized debris collection when the support plate is in a static state; during the upward movement of the support plate, when the first filter plate undergoes slight vibration, the debris and remaining coolant slide better along the inclined surface of the first filter plate again, minimizing the residue of debris and coolant on the surface of the first filter plate.

Detailed Embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] As Figures 1 to 10 shown, the present invention provides a technical solution: a stainless steel casting cutting device, including a cutting table 1, symmetrically and fixedly connected with support seats 2 on the top of the cutting table 1, the support seats 2 are used for placing stainless steel steel pipes, a gantry 3 is fixedly installed above the cutting table 1, a hydraulic cylinder 8 is fixedly installed on the top of the gantry 3, the output end of the hydraulic cylinder 8 is fixedly connected with a protective shell 4, a cutting knife 7 is rotatably connected inside the protective shell 4, a motor 5 is fixedly connected to one side of the protective shell 4, and a transmission structure 6 is arranged between the output shaft of the motor 5 and the shaft rod of the cutting knife 7. Cold liquid tanks 9 are fixedly installed on both sides of the top of the gantry 3, and spray pipes 10 are fixedly communicated with the bottoms of the cold liquid tanks 9. A first water pump 11 is arranged outside each spray pipe 10. A screening assembly is arranged below the cutting knife 7, and the screening assembly is used for separating debris and coolant.

[0027] During operation: This device is suitable for cutting steel pipes in stainless steel castings. When cutting, the steel pipe to be cut is placed above the two support seats 2, and the preset cutting line of the steel pipe is aligned with the lower part of the cutting knife 7. Start the hydraulic cylinder 8, and its output end will drive the protective shell 4 to descend. The protective shell 4 will drive the cutting knife 7 to descend and gradually approach the steel pipe. When the cutting knife 7 is about to contact the outer wall of the steel pipe, start the motor 5, which will drive the cutting knife 7 to rotate through the transmission structure 6. The transmission structure 6 is composed of a transmission ring and a transmission belt. Through the transmission relationship, the cutting knife 7 rotates to cut the steel pipe. At this time, during the cutting process, through the first water pump 11, the coolant in the two cold liquid tanks 9 is sprayed onto the cutting position where the cutting knife 7 contacts the steel pipe through the spray pipes 10 to cool down the cutting knife 7 and the steel pipe. During the cutting process, a large amount of debris and coolant will fall downward, and the debris and coolant will fall into the screening assembly together. The screening assembly will separate the debris and coolant, and the coolant can be centrally collected after separation and recycled back into the cold liquid tank 9 for continued use, while the debris can also be centrally collected for subsequent processing; after the cutting work is completed, start the hydraulic cylinder 8 to drive the protective shell 4 and the cutting knife 7 to rise and reset, thus completing the entire cutting process; through the above embodiments, the screening assembly can collect and screen the debris and coolant generated during the cutting process, so that the coolant can be quickly recovered into the cold liquid tank 9 for continued use; In the above embodiments, through the screening assembly, the debris and coolant generated during the cutting process are effectively separated, so that the coolant can be quickly recovered into the cold liquid tank 9 for continued use, reducing the waste of coolant and lowering the production cost.

[0028] As shown Figures 3 to 5 in the figure, the screening assembly includes a support plate 12. The top of the support plate 12 is triangular. A plurality of second springs 38 are fixedly connected between the bottom of the support plate 12 and the top of the cutting table 1. Hinged members 13 are fixedly connected to both sides of the support plate 12. Shaft rods of the hinged members 13 are fixedly connected with first filter plates 14. Second filter plates 15 are fixedly connected to the surfaces of the first filter plates 14. A V shape is formed between the first filter plates 14 and the second filter plates 15. One ends of the two second filter plates 15 are attached to each other. Side connection plates 16 are fixedly connected to both sides of the first filter plates 14. Protective plates 21 are fixedly connected to both sides of the first filter plates 14 and the second filter plates 15. Circular blocks 17 are disposed in a fitting manner on the bottom surfaces of the side connection plates 16. Shaft rods of each circular block 17 are rotatably connected with clamping seats 36. The clamping seats 36 are fixedly installed on the top of the cutting table 1. A lifting assembly is disposed on one side of the support plate 12. The lifting assembly is used to drive the support plate 12 to rise. Counterweight assemblies are disposed at one ends of the two first filter plates 14 away from the hinged members 13.

[0029] During operation: In the initial state, restricted by the circular blocks 17, a W shape is formed between the two groups of first filter plates 14 and second filter plates 15. During the cutting process when the protective shell 4 and the cutting tool 7 descend, the entire screening assembly remains stationary. When the mixture of debris and coolant drops above the first filter plates 14 or the second filter plates 15, a V shape is formed between the first filter plates 14 and the second filter plates 15. Both the debris and the coolant will slide along the inclined surfaces of the first filter plates 14 and the second filter plates 15. Most of the coolant will drop out through the slots of the first filter plates 14 and the second filter plates 15 during the sliding process, while the debris will slide and concentrate at the intersection of the first filter plates 14 and the second filter plates 15, that is, the bottom of the inner wall of the V shape, forming a concentrated accumulation area, avoiding the random distribution of debris on the plate surface and blocking the slots at easy positions, resulting in the subsequent uniform dropping of the coolant from the slots and forming residues on the surfaces of the first filter plates 14 and the second filter plates 15. The protective plates 21 can prevent the debris and the coolant from splashing during the flowing process. When the protective shell 4 and the cutting tool 7 are lifted and reset after cutting is completed, the support plate 12 will be driven to rise by the lifting assembly. When the support plate 12 rises, it will drive the hinge member 13 and the first filter plate 14 to rise. At this time, under the action of the counterweight assembly, the first filter plate 14 will rotate hingedly around the shaft rod of the hinge member 13. During the hinged rotation of the first filter plate 14, the bottom of the side connection plate 16 always fits against the outer wall of the circular block 17, and the first filter plate 14 gradually forms a slag-discharging posture inclined downward. The debris concentrated at the bottom of the V-shaped inner wall will slide out from both sides along the inclined surface of the first filter plate 14 under the action of gravity; and because the debris blocks some of the slots when concentrated at the intersection of the first filter plate 14 and the second filter plate 15, part of the coolant cannot fall and will also be mixed in the debris stacking area. At this time, the debris and the coolant will flow along the inclined surface of the first filter plate 14 again, and part of the mixed coolant will fall out through the slots of the first filter plate 14 again; Through the above embodiments, the first filter plate 14 and the second filter plate 15 are in a V shape. When the mixture of debris and coolant falls above it, it will slide down along the inclined surface to the intersection, that is, the bottom of the V-shaped inner wall, forming a concentrated accumulation area, avoiding the debris from blocking some of the slots, resulting in the subsequent coolant not being able to fall out evenly from the slots and forming residues on the filter plate surface, improving the screening efficiency. After cutting is completed, the first filter plate 14 rotates hingedly around the shaft rod of the hinge member 13 and gradually forms a slag-discharging posture inclined downward. The debris concentrated at the bottom of the V-shaped inner wall will slide out from both sides along the inclined surface of the first filter plate 14 under the action of gravity, facilitating the centralized treatment of the debris.

[0030] As Figures 6 to 7 shown, the lifting assembly includes two power plates 23. Both sides of the protective shell 4 are fixedly connected with connecting members 22. Two power plates 23 are partially fixedly connected to the bottom of the connecting members 22. A fixed rod 31 is fixedly connected to one side of each power plate 23. A movable block 30 is slidably connected to the outer wall of the fixed rod 31. A fixing plate 24 is fixedly connected to the bottom of each movable block 30. A second hinge seat 25 is fixedly connected to one side of each fixing plate 24. A hinge rod 26 is hinged to the inner wall of each second hinge seat 25. The bottom of the hinge rod 26 abuts against a limiting rod 28. The limiting rod 28 is fixedly connected between the inner walls of the second hinge seat 25. A torsion spring 27 is fixedly connected between one side of the hinge rod 26 and the torsion spring 27. A sliding assembly is arranged on one side of the fixing plate 24, and the sliding assembly is used to drive the movable block 30 to slide on the fixed rod 31.

[0031] During operation: When the protective shell 4 descends, it will drive the power plate 23 to descend through the connecting member 22. When the power plate 23 descends, it will drive the fixed plate 24 and the hinge rod 26 to descend. During the descent of the hinge rod 26, the outer sidewall of the hinge rod 26 will gradually come into contact with the side surface of the support plate 12. At this time, in order for the hinge rod 26 to descend smoothly, the hinge rod 26 will be squeezed by the side surface of the support plate 12 and hinge and rotate around the shaft rod of the fixed plate 24, shortening the distance between the top end of the hinge rod 26 and the fixed plate 24. During this process, the torsion spring 27 will be squeezed and deformed. When the top end of the hinge rod 26 descends below the bottom surface of the support plate 12, the hinge rod 26 will, under the action of the torsion spring 27, hinge and rotate in the reverse direction to restore its original state. When the protective shell 4 ascends, the top end of the hinge rod 26 will ascend. When the hinge rod 26 ascends, its top end will gradually come into contact with the bottom end of the support plate 12. Under the restriction of the limiting rod 28, when the hinge rod 26 continues to ascend, it will not hinge and rotate with the hinge seat two 25 and pass through the support plate 12 smoothly, but will lift the bottom surface of the support plate 12 and ascend together, so that the support plate 12 ascends, and the filter plate one 14 and the filter plate two 15 move, achieving the effect of discharging debris and secondarily screening the coolant; when the hinge rod 26 drives the support plate 12 to ascend to a certain height, under the influence of the sliding assembly, the movable block 30 will slide along the surface of the fixed rod 31, causing the fixed plate 24 and the hinge rod 26 to move laterally. The top end of the hinge rod 26 is separated from the bottom surface of the support plate 12, and the support plate 12 will automatically descend and reset under the action of the spring two 38, and the two groups of filter plates one 14 and filter plates two 15 return to the W-shaped state, entering the next round of cutting preparation; Through the above embodiments, the lifting assembly drives the power plate 23 to move through the ascending and descending of the protective shell 4, and then drives the hinge rod 26 to move. After cutting is completed, the top end of the hinge rod 26 will lift the bottom surface of the support plate 12 and ascend together, so that the support plate 12 ascends, driving the filter plate one 14 and the filter plate two 15 to move, achieving the effect of discharging debris and secondarily screening the coolant, without manual intervention, improving the automation degree and working efficiency of the device.

[0032] As Figures 6 to 7 shown, the sliding assembly includes two iron blocks 29, the two iron blocks 29 are respectively fixedly connected to the other side of the fixed plate 24, an electromagnet 33 is fixedly installed on the top of the cutting table 1, the electromagnet 33 is located on one side of the iron block 29, a spring one 32 is arranged outside the fixed rod 31, and the two ends of the spring one 32 are respectively fixedly connected to one side of the movable block 30 and one side of the power plate 23. The rigidity of the spring one 32 is much greater than that of the torsion spring 27.

[0033] During operation: When the fixed plate 24 and the hinge rod 26 lift the bottom surface of the support plate 12 synchronously and rise, an electric current is passed through the through electromagnet 33. Since an iron block 29 is fixedly installed on one side of the fixed plate 24, when it rises to a certain height, the hydraulic cylinder 8 is controlled to make the whole stay for a period of time. At this time, the iron block 29 does not enter the suction range of the through electromagnet 33, and the support plate 12 remains stationary at the lifted height, giving the debris and coolant on the surface of the filter plate 14 time to slide down along the inclined plane. After the debris is completely processed and continues to rise, the iron block 29 will enter the suction range of the through electromagnet 33, causing the movable block 30 to slide laterally along the outer wall of the fixed rod 31 and compress the first spring 32. At this time, the movable block 30 will drive the fixed plate 24 and the hinge rod 26 to move laterally synchronously, so that the top end of the hinge rod 26 is disengaged from the bottom surface of the support plate 12. After the iron block 29 rises to the original position, the through electromagnet 33 is powered off, and the movable block 30 moves laterally in the reverse direction under the action of the first spring 32 to reset, preparing for the next cutting and lifting; by setting the rigidity of the first spring 32 to be much greater than the rigidity of the torsion spring 27, when the hinge rod 26 descends and is squeezed by the side of the support plate 12, the hinge rod 26 will only be hinged and rotated to squeeze the torsion spring 27, and will not cause the movable block 30 to squeeze the first spring 32 and move laterally; the sliding assembly enables the support plate 12 to automatically reset after slag discharge through the lateral disengagement mechanism, forming a complement to the upward drive of the lifting assembly to ensure the integrity of the process cycle.

[0034] As Figures 4 to 6 shown, the counterweight assembly includes a plurality of first hinge seats 18, and the plurality of first hinge seats 18 are respectively fixedly connected to the bottoms of the two filter plates 14. Cables 19 are hinged to the inner walls of the first hinge seats 18, and the bottoms of the cables 19 are fixedly connected to conical counterweight blocks 20.

[0035] During operation: When the support plate 12 rises, since the filter plate 14 is hingedly connected to the hinge member 13, under the action of the conical counterweight block 20, the filter plate 14 will be hingedly rotated to form a slag discharge posture, and the cable 19 will adaptively hinge and rotate with the first hinge seat 18, so that the center of gravity of the conical counterweight block 20 always remains vertically downward, and the total mass of the conical counterweight block 20 should be set between 2 kg and 4 kg, avoiding the mass of the conical counterweight block 20 being too light to enable the hinge member 13 to be hingedly rotated to form a slag discharge posture, and also avoiding the mass of the conical counterweight block 20 being too high, which will hinder the support plate 12 from descending to the initial position when the support plate 12 descends and resets under the action of the second spring 38 after the support plate 12 is disengaged from the hinge rod 26.

[0036] As Figure 4 、 Figure 5 and Figure 8As shown, convex blocks 37 are symmetrically and fixedly connected to the outer wall of the circular block 17. A rotating assembly is provided on one side of the circular block 17, and the rotating assembly enables the circular block 17 to rotate during the entire cutting process.

[0037] During operation: During the stationary and rising processes of the support plate 12, the circular block 17 plays an important role. It can make the two filter plates 14 and the filter plate 15 maintain a W-shaped posture between them in the initial state, facilitating the concentration of debris, and also restricting the position of the filter plate 14 after articulated rotation, enabling the filter plate 14 to maintain a stable slag discharge posture. During the entire cutting process, the circular block 17 can rotate on its own. The rotation causes the convex block 37 to continuously press against the bottom surface of the side connection plate 16, causing the filter plate 14 to move up and down with a slight vibration effect. This enables debris and coolant to better slide down along the inclined surfaces of the filter plate 14 and the filter plate 15 for screening and centralized debris collection when the support plate 12 is in a stationary state. When the support plate 12 is rising, when the filter plate 14 vibrates slightly, the debris and remaining coolant slide down along the inclined surface of the filter plate 14 again, minimizing the residue of debris and coolant on the surface of the filter plate 14.

[0038] As Figure 2 、 Figure 3 and Figure 8 shown, the rotating assembly includes a plurality of rack plates 34. The plurality of rack plates 34 are respectively fixedly connected to one side of the two power plates 23. The teeth of the plurality of rack plates 34 are all engaged with a gear 35, and the gear 35 is fixedly connected to one end of the shaft of the circular block 17.

[0039] During operation: When the power plate 23 descends and rises, it will drive the rack plate 34 to rise and fall. When the rack plate 34 rises and falls, it will drive the gear 35 to rotate, so that the circular block 17 always maintains a rotating motion state during the entire cutting process, enabling the filter plate 14 and the filter plate 15 to better process debris and coolant.

[0040] As Figure 2 and Figure 9 shown, collection boxes 39 and collection boxes 40 are provided below the filter plate 14. The collection box 39 is directly below the bottom surface of the filter plate 14, and the collection box 40 is located below the side of the top end of the filter plate 14. The collection box 39 and the collection box 40 are both located on the top of the cutting table 1. One end of the collection box 39 is fixedly communicated with a communication pipe 41. A second water pump 42 is provided outside the communication pipe 41. The end of the communication pipe 41 away from the collection box 39 is fixedly communicated with the coolant tank 9.

[0041] During operation: The collection box 39 is located directly below the bottom surface of the first filter plate 14 and is used to collect the coolant that falls out of the slots in the first filter plate 14 and the second filter plate 15. The collection box 40 is located below the side of the top port of the first filter plate 14 and is used to collect the debris that slides out from the port of the first filter plate 14. The coolant in the collection box 39 is timely returned to the inside of the coolant tank 9 through the connecting pipe 41 and the second water pump 42, and the coolant is cooled and reused after being returned to the inside of the coolant tank 9.

[0042] A stainless steel casting cutting device, and now a cutting process applicable to this device is proposed: S1. Start the hydraulic cylinder 8 to drive the protective shell 4 and the cutting tool 7 to descend. At the same time, start the motor 5 to drive the cutting tool 7 to rotate through the transmission structure 6 for cutting. The first water pump 11 sprays the coolant in the coolant tank 9 to the cutting area through the spray pipe 10 for cooling, and the mixture of debris and coolant falls onto the screening assembly; S2. The mixture of debris and coolant slides down along the V-shaped first filter plate 14 and the second filter plate 15. Most of the coolant falls into the collection box 39 through the slots, and the debris accumulates at the bottom of the V-shaped inner wall; S3. After cutting is completed, the protective shell 4 and the cutting tool 7 rise, driving the power plate 23 to rise, and further causing the articulated rod 26 to lift the support plate 12. The support plate 12 drives the first filter plate 14 to rise. Under the action of the counterweight assembly, the first filter plate 14 forms a slag discharging posture.

[0043] S4. The debris and the remaining coolant slide down along the inclined surface of the first filter plate 14 again, and part of the coolant falls into the collection box 39 through the slots; S5. After rising to a certain height, the electromagnet 33 is energized, and the movable block 30 drives the fixed plate 24 and the articulated rod 26 to move horizontally. The top of the articulated rod 26 is disengaged from the bottom surface of the support plate 12; S6. The support plate 12 descends and resets under the action of the second spring 38, and the first filter plate 14 returns to the W-shaped state; S7. The coolant in the collection box 39 is returned to the coolant tank 9 through the connecting pipe 41 and the second water pump 42, and the debris falls into the collection box 40.

[0044] A stainless steel casting cutting process, and the lifting assembly and the sliding assembly specifically include the following steps: M1. Drive the power plate 23 to move through the rise and fall of the protective shell 4, and then drive the articulated rod 26 to move. After cutting is completed, the top of the articulated rod 26 will lift the bottom surface of the support plate 12 to rise together, so that the support plate 12 rises, driving the first filter plate 14 and the second filter plate 15 to move. The first filter plate 14 rotates in an articulated manner with the shaft rod of the articulated part 13 as the axis, and gradually forms a slag discharging posture that slopes downward. Under the action of gravity, the debris concentrated at the bottom of the V-shaped inner wall will slide out from both sides along the inclined surface of the first filter plate 14; When the iron block 29 enters the suction range of the electromagnet 33, the movable block 30 slides laterally along the outer wall of the fixed rod 31 and compresses the first spring 32. At this time, the movable block 30 drives the fixed plate 24 and the hinge rod 26 to move laterally synchronously, so that the top of the hinge rod 26 is disengaged from the bottom surface of the support plate 12. After the iron block 29 rises to the original position, the electromagnet 33 is powered off, and the movable block 30 moves laterally in the reverse direction and resets under the action of the first spring 32, preparing for the next cutting and lifting.
