[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] Example: Refer to Figures 1-9 A steel rod cutting device for flange processing includes a cutting machine case 1 and a cutting assembly, and further includes: a first sealing slide 2, which is slidably arranged on the cutting machine case 1, and the cutting assembly is arranged on the first sealing slide 2; a second sealing slide 4, which is arranged in the cutting machine case 1, and the second sealing slide 4 is slidably connected to the first sealing slide 2; the first sealing slide 2, the second sealing slide 4, and the cutting machine case 1 are sealed with each other; a movable slot 3 is provided on the first sealing slide 2, and a rod hole 5 is provided on the second sealing slide 4, and the steel rod passes through the movable slot 3 and the rod hole 5 in turn and penetrates into the cutting machine case 1; during cutting, after the coolant in the cutting machine case 1 overflows the steel rod, the cutting assembly descends and cuts the steel rod extending into the cutting machine case 1.

[0033] In this embodiment, the steel rod is first inserted into the cutting machine case 1 through the first sealing slide 2 and the second sealing slide 4, and the coolant water level inside the cutting machine case 1 is raised and the steel rod is lowered, so that the steel rod is completely immersed in the coolant. Then the first sealing slide 2 and the cutting assembly on the first sealing slide 2 are lowered, and the cutting end of the cutting assembly moves downward and completely enters the coolant and contacts the steel rod. Then, it continues to descend and cuts a circular plate of corresponding thickness for processing and making flange end plates from the end of the steel rod extending into the cutting machine case 1.

[0034] The mutual sealing arrangement between the first sealing slide 2, the second sealing slide 4 and the cutting machine case 1 can effectively prevent leakage of the coolant during the cutting process, ensuring the stability and safety of the cutting environment; and the first sealing slide 2 and the second sealing slide 4 can slide during the sealing process, so that the steel rod can be easily inserted into the cutting machine case 1, and the position of the steel rod can be adjusted as needed, thereby improving the flexibility and convenience of operation;

[0035] After the steel rod is completely immersed in the coolant, the cutting assembly descends to contact the steel rod and cuts it, so that the coolant fully contacts the output end of the cutting assembly, the steel rod, and the surface of the steel rod to be cut, thereby improving the cooling effect of the cutting assembly and the steel rod. At the same time, since the cutting operation is completely carried out in the liquid, during the cutting process, the coolant can effectively absorb and disperse the vibration and heat generated during the cutting process, thereby reducing the deformation or offset of the steel rod and the cutting end due to heat or vibration, ensuring the accuracy and stability of the cutting, and improving the cutting efficiency and cutting quality.

[0036] And because the steel rod and the cutting end are completely immersed in the coolant during the cutting process, it can not only improve the cutting efficiency and quality, but also effectively reduce the sparks and spatters generated during cutting, and improve the safety of operation.

[0037] Reference Figure 1 、 Figure 4-Figure 6 and Figure 8 The cutting assembly includes a mounting shaft 7 rotatably connected to the first sealing slide 2, and the mounting shaft 7 extends to one end inside the cutting machine chassis 1 and is fixedly mounted with a first mounting disk 9, a driving wheel 10 is fixedly connected to the first mounting disk 9, a cutting line 12 is coupled to the driving wheel 10, and a second mounting disk 11 is fixed to the driving wheel 10 by bolts. A driving unit is provided on one side of the first sealing slide 2 located outside the cutting machine chassis 1; the driving unit includes a mounting bracket 15 fixedly mounted on the first sealing slide 2, a first motor 16 is fixedly mounted on the mounting bracket 15, and the output shaft of the first motor 16 is fixedly connected to the mounting shaft 7; two groups of mounting shafts 7 are provided, and the two groups of mounting shafts 7 are symmetrically arranged on the first sealing slide 2, and the two groups of mounting shafts 7 rotate synchronously through the first synchronous pulley group 8; it also includes an electric telescopic cylinder 41, which is arranged on the outside of the cutting machine chassis 1, and the output end of the electric telescopic cylinder 41 is fixedly connected to the first sealing slide 2 through a connecting plate 42, a first slider 14 is fixedly connected to the first sealing slide 2, a guide rail 13 is fixedly mounted on the cutting machine chassis 1, and the first slider 14 is slidably connected to the guide rail 13.

[0038] In this embodiment, the electric telescopic cylinder 41 drives the first sealing slide 2 to move up and down, so that the first sealing slide 2 moves up and down along the guide rail 13, thereby driving the cutting assembly to move up or down.

[0039] Start the first motor 16, and the first motor 16 drives the installation shaft 7 to rotate. The two installation shafts 7 rotate synchronously through the first synchronous pulley group 8. The first synchronous pulley group 8 consists of a wire pulley rotating on the first sealing slide 2, a pulley fixed on the installation shaft 7, and a belt. When the two installation shafts 7 rotate synchronously, the installation shaft 7 drives the first installation disk 9 to rotate. The first installation disk 9 rotates the driving wheel 10 and the second installation disk 11. The driving wheel 10 rotates to rotate the cutting line 12. During the rotation of the cutting line 12, the first sealing slide 2 is driven to descend by the electric telescopic cylinder 41. The first sealing slide 2 drives the cutting line 12 to descend. The rotating cutting line 12 cuts the steel rod during the descent process to cut out the steel plate for making the flange.

[0040] The cutting line 12 is completely immersed in the coolant, which can ensure that the heat generated during the cutting process is quickly absorbed and taken away, thereby effectively reducing the temperature of the cutting area, helping to reduce the deformation of the cutting end and the steel rod, and improving the accuracy and stability of the cutting.

[0041] Cutting entirely in coolant can significantly reduce the thermal impact during the cutting process, making the cut end face flatter and smoother, thereby improving the cutting quality.

[0042] Cutting is performed entirely in the coolant, so that the coolant can also play a better role in lubrication and cleaning, reducing friction and wear between the cutting wire 12 and the steel rod, thereby extending the service life of the cutting wire 12.

[0043] When the cutting wire 12 is rotating and cutting, it will stir the coolant and make it flow, which not only helps to quickly take away the heat generated during the cutting process, but also can flush out metal chips and impurities from the cutting gap, keeping the cutting area clean. In addition, the flow of coolant can also play a lubricating role, reducing the friction between the side of the cutting wire 12 and the gap between the steel rod, further reducing the cutting temperature and improving the cutting efficiency.

[0044] Reference Figure 1-Figure 5, also includes a sealing box 21, a sliding rod 24 is provided on the sealing box 21, a discharge plate 25 is fixedly installed on the top of the sliding rod 24, a connecting rod 27 is fixedly connected to the discharge plate 25, a second slider 28 is fixedly installed on the connecting rod 27, the second slider 28 is slidably connected to the first guide rail 13, and the connecting rod 27 is fixedly connected to the second sealing slide 4; a telescopic bracket 29 is fixedly installed on the top of the sealing box 21, and also includes a transmission screw 30, the two ends of the transmission screw 30 are respectively rotatably connected to the second sealing slide 4 and the lifting end of the telescopic bracket 29, and the transmission screw 30 is provided with two. The two transmission screws 30 rotate synchronously through the second synchronous pulley set 31, and a third motor 33 is fixedly installed on the telescopic bracket 29. The output end of the third motor 33 is fixedly connected to the transmission screw 30, and a pusher block 32 is threadedly connected to the transmission screw 30; a rod hole 5 is fixedly connected to a sealing ring 6, and the steel rod passes through the sealing ring 6 and extends into the cutting machine case 1, wherein the sealing ring 6 is used to achieve a seal between the steel rod and the rod hole 5; a piston plate 22 is slidably connected to the sealing box 21, and a sealing strip 23 is sleeved on the piston plate 22. One end of the sliding rod 24 extends to the sealing box 21 and is fixedly connected to the piston plate 22, and an elastic member 26 is sleeved on the sliding rod 24. The two ends of the elastic member 26 are respectively connected to the top of the sealing box 21 and the discharge plate 25; it also includes a filter assembly, the input end of the filter assembly is connected to the cutting machine case 1 through a third water pipe 40, and the output end of the filter assembly is connected to the sealing box 21 through a first water pipe 35, and the first water pipe 35 is provided with a first one-way control valve 36; the output end of the sealing box 21 is connected to the cutting machine case 1 through a second water pipe 37, and the second water pipe 37 is provided with a second one-way control valve 38.

[0045] First, before the steel rod is placed on the discharge plate 25, the elastic member 26 is in an expanded state, and the pusher block 32 is inserted to block the sealing ring 6, thereby achieving sealing of the cutting chassis 1;

[0046] Secondly, the elastic member 26 can be a coil spring or a spring disc. In addition, when the elastic member 26 is in the expanded state, the positions of the piston plate 22 and the sealing strip 23 inside the sealing box 21 rise. During this process, the first one-way control valve 36 is opened. When the piston plate 22 and the sealing strip 23 rise, a negative pressure is generated inside the sealing box 21. Under the action of the pressure difference, the coolant in the cutting chassis 1 passes through the third water pipe 40, the filter assembly, and the first water pipe 35 in sequence and enters the sealing box 21, thereby lowering the water level inside the cutting chassis 1 and making the water level of the cooling water in the cutting chassis 1 lower than the rod hole 5. Then, the first one-way control valve 36 is closed.

[0047] Then, the third motor 33 is started, and the third motor 33 drives the transmission screw 30 to rotate. The two transmission screws 30 rotate synchronously through the second synchronous pulley set 31. When the transmission screw 30 rotates, the pusher block 32 is driven to move, so that the pusher block 32 is separated from the sealing ring 6 and reset.

[0048] Then, the steel rod is placed on the discharge plate 25, and the third motor 33 is started to make the pusher block 32 abut against the steel rod, and then drive the steel rod to move and insert into the sealing ring 6 until the steel rod is inserted into the cutting machine box 1;

[0049] Then, the second one-way control valve 38 is opened. Under the action of the weight of the steel rod itself, the discharge plate 25 descends, driving the slide rod 24, the piston plate 22, and the sealing strip 23 to descend. During this process, the piston plate 22 and the sealing strip 23 cooperate to squeeze the coolant in the sealing box 21 into the cutting machine case 1 through the second water pipe 37, thereby raising the coolant level in the cutting machine case 1 and allowing the end of the steel rod inserted into the cutting machine case 1 to be completely immersed in the coolant.

[0050] Before starting cutting, the second one-way control valve 38 is closed to prevent the elastic member 26 from rebounding and returning to its original position due to the weight reduction of the steel rod during the subsequent cutting process.

[0051] In summary, in this embodiment, the water level inside the cutting machine case 1 is automatically adjusted by utilizing the weight of the steel rod, the elastic member 26, and the piston plate 22, thereby preventing leakage of the coolant inside the cutting machine case 1 when the steel rod is inserted into the cutting machine case 1 and when the steel rod is completely cut, thereby ensuring the stability of cutting performed entirely in the coolant.

[0052] Reference Figure 1 and Figure 9 The filter assembly includes an installation box 34, in which a filter block 39 is arranged. The drainage end of the third water pipe 40 is higher than the upper surface of the filter block 39, and the water inlet end of the first water pipe 35 is lower than the upper surface of the filter block 39.

[0053] Among them, the filter block 39 can be a zeolite molecular sieve, and the coolant is filtered by using the micropores on the zeolite molecular sieve. In the installation box 34, a cavity is provided above the filter block 39, which is used to store iron filings intercepted by the zeolite molecular sieve. In this embodiment, the sealing cover on the top of the installation box 34 can be opened to clean the iron filings in the installation box 34.

[0054] A control valve may be installed on the third water pipe 40 to block the coolant from flowing in the third water pipe 40 , thereby improving the convenience of cleaning debris in the installation box 34 .

[0055] Reference Figure 1 、 Figure 4 、 Figure 5 and Figure 7A conveyor is obliquely arranged on the cutting machine chassis 1, and the conveyor includes a rotating shaft 17 rotatably connected to the cutting machine chassis 1, a conveyor belt 18 is rotatably connected to the rotating shaft 17, a baffle 19 is fixedly connected to the conveyor belt 18, a second motor 20 is fixedly connected to the outer wall of the cutting machine chassis 1, an output end of the second motor 20 is fixedly connected to the rotating shaft 17, and a material guide plate 43 is fixedly connected to the inner wall of the cutting machine chassis 1.

[0056] In this embodiment, the circular plate cut from the steel rod slides onto the conveyor belt 18 through the inclined guide plate 43, and the second motor 20 is started. The second motor 20 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the conveyor belt 18 to rotate. The conveyor belt 18 drives the circular plate to rise through the baffle 19 until it is discharged from the cutting machine case 1. During the rotation of the conveyor belt 18, the baffle 19 drives the water in the cutting machine case 1 to flow, thereby improving the heat dispersion effect of the coolant in the cutting area, and further improving the cooling effect during cutting.

[0057] In summary, the device simplifies the operation process: through the motor drive, the coordination of the synchronous belt pulley set and the introduction of the conveyor, the steel bar cutting, coolant filtration and circular plate transmission are automated and continuous, which greatly simplifies the operation process and reduces the need for manual intervention.

[0058] The device integrates multiple functions (such as cutting, filtering, transmission, etc.) into one, reducing the equipment footprint, improving space utilization, and also facilitating unified management and maintenance.

[0059] When the device cuts the steel rod, the coolant completely covers the steel rod and the cutting line 12, ensuring sufficient cooling during the cutting process, reducing deformation of the heat-affected zone and the cut end face, and improving cutting accuracy and quality. The automated cutting operation reduces manual errors and vibration interference, making the cutting process more stable and reliable, and ensuring the consistency of cutting efficiency and the stability of product quality.

[0060] The device uses a filter component to efficiently filter the coolant, remove tiny particles and impurities, ensure the cleanliness and service life of the coolant, realize the recycling of the coolant, and save resources.

[0061] The device has a clear structure and easy-to-disassemble and replace components, which reduces maintenance costs and time, improves the maintainability and service life of the equipment, and highly automated operation and precise coolant management reduce equipment failure rate and downtime, and improve equipment reliability and stability.

[0062] In summary, the device has the advantages of high automation and integration, high cutting quality and strong stability, precise coolant management and energy saving and environmental protection, convenient maintenance and long service life, as well as strong adaptability and high flexibility.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
