Description

Technical Field

[0001] This invention relates to the field of cutting and sorting equipment technology, specifically to an integrated cutting and sorting device for ductile iron profiles and its usage method. Background Technology

[0002] An integrated cutting and sorting device is a piece of equipment that integrates cutting and sorting functions. It can complete the cutting and sorting of materials in the same operation. This device uses precise mechanical or laser cutting technology to divide materials into the required size and shape. At the same time, it uses an automated sorting system to quickly classify and organize the cut materials according to category, size or other standards. It is widely used in industrial production, logistics, food processing and other fields, effectively improving production efficiency and the accuracy of material handling. Ductile iron profiles are cast iron profiles with specific shapes and sizes produced by continuous casting process using ductile iron as raw material. Due to the spherical distribution of graphite inside, ductile iron profiles have high strength, high toughness and good wear resistance. These characteristics make them superior to ordinary gray cast iron profiles in mechanical properties. In the production process of ductile iron profiles, in order to improve production efficiency and material handling accuracy, an integrated cutting and sorting device is usually used to complete the cutting and sorting of profiles. When cutting and sorting ductile iron profiles with columnar structures of different diameters, cutting and sorting are two independent processes. The separate cutting and sorting processes may lead to errors or damage to the materials during the transfer between different equipment, which may further affect product quality and production costs. Therefore, in order to address the above problems, an integrated cutting and sorting device for ductile iron profiles and its usage method are proposed. Summary of the Invention

[0006] As a further optimization of the present invention, the following features are provided: the inner side of the base frame is fixedly connected to the cylinder body of the first electric hydraulic cylinder; a push plate is fixedly connected to the end of the piston rod of the first electric hydraulic cylinder; a sliding hole is provided on the inner side of the push plate; the push plate is slidably connected to the guide column through the sliding hole; the bottom end of the guide column is fixedly connected to the inner side of the base frame; and a frame is fixedly connected to the top end of the base frame and the top end of the guide column.

[0007] As a further optimization of the present invention, the top of the push plate is fixedly connected to a bearing seat, and an arc-shaped rotating roller is rotatably connected to the inner side of the bearing seat.

[0008] As a further optimization of the present invention, the guide column is slidably connected to the inner side of the sliding groove opened in the guide plate, and an expandable gap is provided between the guide column and the hollow rubber ball.

[0009] As a further optimization of the present invention, the frame is fixedly connected to the cylinder body of the second electric hydraulic cylinder, the piston rod of the second electric hydraulic cylinder is movable inside the through hole of the frame, and an extension frame is fixedly connected to the end of the piston rod of the second electric hydraulic cylinder, the bottom end of the extension frame is fixedly connected to the top end of the guide plate.

[0010] As a further optimization of the present invention, a linear module is fixedly connected to the upper part of the frame, and a laser cutting machine is fixedly connected to the bottom end of the slide plate of the linear module. Both the linear module and the laser cutting machine are deviated from the movement path of the second electric hydraulic cylinder.

[0011] As a further optimization of the present invention, the outer side of the cylindrical shell is fixedly connected to the inner side of the guide plate, and the front and rear ends of the double-fixed plate are both fixedly connected to sliders, and the double-fixed plate slides inside the positioning plate through the sliders.

[0012] As a further optimization of the present invention, the following features are provided: the inner column is fixedly connected to the top of the spring near its upper end; the outer side of the rubber sealing ring is in contact with the inner side of the cylinder shell; the inner side of the cylinder shell is connected to the inner side of the rubber hollow ball through an oil passage and the inner side of the solenoid valve; the rubber hollow ball is filled with hydraulic oil; and the pressure roller and the arc-shaped rotating roller are aligned vertically.

[0013] A method for using an integrated cutting and sorting device for ductile iron profiles; Step 1: Before cutting, profile bodies of different diameters are placed on their respective upper ends of the load-bearing rollers. The structure of the load-bearing rollers is the same as that of the bearing seat and the curved roller. The shape of the curved roller is the same as that of the roller of the load-bearing roller. After multiple profile bodies are placed, the push mechanism pushes the profile bodies to the right. The profile bodies enter between the curved roller and the pressure roller. The top of the curved roller is flush with the top of the load-bearing roller. After the profile bodies move to the right, they come into contact with the curved roller. The curved roller rotates due to friction. The position of the profile body to be cut is aligned with the cutting range of the laser cutting machine. Step 2: When fixing multiple profile bodies, multiple solenoid valves are open. The elastic tension of the springs causes most of the built-in columns to be located outside the cylinder shell. The double fixing plates are far from the cylinder shell. Most of the hydraulic oil inside the rubber hollow ball is concentrated inside the cylinder shell. The second electric hydraulic cylinder is activated to push the extension frame and guide plate downward. The guide plate simultaneously drives multiple fixing components downward. The sliding groove slides on the outside of the guide column. The bottom end of the pressure roller is in contact with the top end of its corresponding profile body. When the guide plate moves downward, it will drive the cylinder shell, solenoid valves and rubber hollow ball downward. The cylinder shell pulls the spring and deforms. The built-in columns maintain the downward trend. The built-in columns drive the double fixing plates and pressure rollers downward to squeeze the profile body. The rubber sealing ring seals the built-in columns and cylinder shell. The hydraulic oil inside the cylinder shell enters the rubber hollow ball through the oil passage and solenoid valve. The solenoid valve is closed. Step 3: During the cutting and sorting of the profile body, the linear module controls the position of the laser cutting machine. The laser emitted by the laser cutting machine cuts the profile body. After the profile body is cut, multiple solenoid valves open simultaneously, controlling the first electric hydraulic cylinder to drive the push plate, shaft seat and curved roller to move downward. The second electric hydraulic cylinder controls the guide plate and multiple fixed components to move downward simultaneously. The elastic tension of the spring keeps the pressure roller in contact with the profile body. The top of the curved roller is aligned with the bottom of the receiving groove. Multiple solenoid valves are closed to position the internal column and cylinder shell. The second electric hydraulic cylinder is controlled to move multiple fixed components away from the profile body. The pushing mechanism pushes the cut profile body into the receiving groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the support design, which includes a load-bearing roller, a shaft seat, an arc-shaped rotating roller, and a pressure roller, can improve the stability of the support for ductile iron profiles of different diameters, preventing the profiles from shifting or detaching during the cutting process due to unstable support. This ensures the accuracy and quality of the cutting. At the same time, when the profiles are moved, since there is no friction between the profiles and external objects, it can effectively avoid scratches, wear, and other damage to the profile surface caused by friction, ensuring the integrity of the profile surface. This is of great significance for subsequent processing and use, and helps to improve the overall quality of the product. 2. In this invention, the second electric hydraulic cylinder, passive component, and fixing component enable simultaneous fixing of ductile iron profiles of various diameters, greatly improving the versatility and flexibility of the equipment. This allows the equipment to meet the processing requirements of different specifications of profiles without the need for frequent replacement of fixing devices, saving time and labor costs. Furthermore, through precise hydraulic and elastic tension control, the deformation of profiles caused by improper fixing force is significantly reduced, effectively protecting the structural integrity of the profiles and avoiding quality defects caused by excessive compression or insecure fixing, thereby improving the product qualification rate. 3. In this invention, the supporting and cutting components allow for individual transfer of ductile iron profiles by workers, reducing collisions and compression during transfer and gradually lowering the risk of damage caused by collisions. This effectively protects the appearance and structure of the profiles. Furthermore, the automated control enables continuous cutting and sorting operations, significantly improving processing efficiency, shortening the production cycle, and better adapting to large-scale profile processing operations.

[0019] Please see Figures 1-8 The present invention provides a technical solution: An integrated cutting and sorting device for ductile iron profiles and its usage method are disclosed.

[0020] As a further implementation of this solution, the feeding assembly 1 includes a base plate 11, an arch frame 12 fixedly connected to the top of the base plate 11, a storage cylinder 13 fixedly connected to the inner side of the arch frame 12, a receiving groove 17 opened on the inner side of the storage cylinder 13, the receiving groove 17 is located at the upper end of the frame 31, a load-bearing seat 14 fixedly connected to the top of the arch frame 12, a load-bearing roller 15 fixedly connected to the top of the load-bearing seat 14, a profile body 16 placed on the upper end of the roller of the load-bearing roller 15, the outer periphery of the load-bearing roller 15 is curved, and a base frame 21 is fixedly connected to the right side of the base plate 11. Through the above configuration, this structural design can provide stable support for ductile iron profiles of different diameters, prevent the profiles from shifting or detaching during the cutting process, and ensure the accuracy and quality of the cutting. At the same time, the curved surface design of the load-bearing roller 15 can effectively reduce the friction between the profile and the supporting components, protect the integrity of the profile surface, and improve the overall quality of the product. As a further implementation of this solution, the inner side of the base frame 21 is fixedly connected to the cylinder body of the first electric hydraulic cylinder 22. The piston rod end of the first electric hydraulic cylinder 22 is fixedly connected to a push plate 23. A sliding hole is opened on the inner side of the push plate 23. The push plate 23 is slidably connected to the guide column 26 through the sliding hole. The bottom end of the guide column 26 is fixedly connected to the inner side of the base frame 21. The top end of the base frame 21 and the top end of the guide column 26 are fixedly connected to a frame 31. Through the above settings, this hydraulic drive design can achieve precise positioning and stable movement of the profile, ensuring that the profile always stays in the correct position during the cutting and sorting process. At the same time, the sliding hole design of the push plate 23 and the sliding connection of the guide column 26 can provide a good guiding effect, improve the operating stability and reliability of the equipment, and reduce errors caused by mechanical vibration. As a further implementation of this solution, a bearing seat 24 is fixedly connected to the top of the push plate 23, and an arc-shaped roller 25 is rotatably connected to the inner side of the bearing seat 24. Through the above-mentioned arrangement, this rotatable connection design enables the arc-shaped roller 25 to rotate automatically by friction during the movement of the profile, reducing the friction between the profile and the supporting components, protecting the surface of the profile, improving the smoothness of the profile movement, ensuring the efficient execution of the cutting and sorting process, and also serving as a support for the profile body 16. As a further implementation of this solution, the guide column 26 is slidably connected to the inner side of the sliding groove 44 opened in the guide plate 41. An expandable gap is provided between the guide column 26 and the rubber hollow ball 59. Through the above-mentioned setting, this sliding connection design can provide a stable guiding effect for the guide column 26, ensuring its accuracy and stability during movement. At the same time, the expandable gap design between the guide column 26 and the rubber hollow ball 59 can adapt to profiles of different diameters, improve the versatility and flexibility of the equipment, and meet the processing needs of various specifications of profiles. As a further implementation of this solution, the frame 31 is fixedly connected to the cylinder body of the second electric hydraulic cylinder 32. The piston rod of the second electric hydraulic cylinder 32 moves inside the through hole of the frame 31. An extension frame 33 is fixedly connected to the end of the piston rod of the second electric hydraulic cylinder 32. The bottom end of the extension frame 33 is fixedly connected to the top end of the guide plate 41. Through the above settings, this hydraulic drive design can achieve precise control of the guide plate 41, ensuring that the profile can move quickly and accurately to the designated position during the cutting and sorting process. At the same time, the piston rod of the second electric hydraulic cylinder 32 moves inside the through hole of the frame 31, which can provide stable power output and improve the operating efficiency and reliability of the equipment. As a further implementation of this solution, a linear module 34 is fixedly connected to the upper part of the frame 31. A laser cutter 35 is fixedly connected to the bottom of the slide plate of the linear module 34. Both the linear module 34 and the laser cutter 35 are offset from the movement path of the second electric hydraulic cylinder 32. Through the above setting, this offset design can ensure that the linear module 34 and the laser cutter 35 will not interfere with the movement path of the second electric hydraulic cylinder 32 during the operation of the equipment, thus ensuring the normal operation of the equipment. At the same time, the slide plate design of the linear module 34 can provide stable support and guidance, improving the operating accuracy and stability of the equipment. As a further implementation of this solution, the outer side of the cylindrical shell 55 is fixedly connected to the inner side of the guide plate 41, and the front and rear ends of the double fixed plate 51 are fixedly connected to sliders. The double fixed plate 51 slides inside the positioning plate 43 through the sliders. Through the above-mentioned arrangement, this slider design can provide a stable guiding effect for the double fixed plate 51, ensuring its accuracy and stability during movement. As a further implementation of this solution, the upper part of the built-in column 53 is fixedly connected to the top of the spring 56. The outer side of the rubber sealing ring 54 is fitted with the inner side of the cylinder shell 55. The inner side of the cylinder shell 55 is connected to the inner side of the rubber hollow ball 59 through the oil passage 57 and the inner side of the solenoid valve 58. The rubber hollow ball 59 is filled with hydraulic oil. The pressure roller 52 and the arc-shaped rotating roller 25 are aligned vertically. Through the above settings, this hydraulic and elastic tension control design can achieve precise fixing of the profile, significantly reducing the phenomenon of profile deformation caused by improper fixing force. At the same time, the vertical alignment of the pressure roller 52 and the arc-shaped rotating roller 25 can ensure that the profile remains stable during the cutting and sorting process, improving the operating efficiency of the equipment and the product quality.

[0021] Workflow: Before cutting, profile bodies 16 of different diameters are placed on their respective upper ends of the supporting rollers 15. The structure of the supporting rollers 15 is the same as that of the bearing seat 24 and the curved roller 25. Simultaneously, the shape of the curved roller 25 is the same as that of the rollers of the supporting rollers 15. This shape design allows the placed profile bodies 16 to be close to the middle of the rollers of the supporting rollers 15. After multiple profile bodies 16 are placed, the existing pushing mechanism pushes the profile bodies 16 to the right until they enter between the curved roller 25 and the pressure roller 52. At this point, the curved roller... The top of roller 25 is flush with the top of load-bearing roller 15. When the profile body 16 moves to the right, the profile body 16 will contact the arc roller 25. The arc roller 25 will rotate due to friction. At the same time, the position of the profile body 16 to be cut is aligned with the cutting range of the laser cutting machine 35. This support design can not only improve the stability of the support for profile bodies 16 of different diameters and prevent the profile body 16 from falling off, but also prevent the profile body 16 from rubbing against external objects when moving the profile body 16, ensuring the integrity of the surface of the profile body 16. When multiple profile bodies 16 are fixed, multiple solenoid valves 58 are in the open state. Through the elastic tension of springs 56, most of the internal pillars 53 are located outside the cylindrical shell 55, and the double fixing plates 51 are far from the cylindrical shell 55. Most of the hydraulic oil inside the hollow rubber ball 59 is concentrated inside the cylindrical shell 55. The second electric hydraulic cylinder 32 is activated to push the extension frame 33 and guide plate 41 downwards. The guide plate 41 simultaneously drives multiple fixing components 5 downwards. The sliding groove 44 slides on the outside of the guide pillar 26, serving a guiding function. When the bottom end of the pressure roller 52 is in contact with the top end of its corresponding profile body 16, the guide plate 41, as it moves downwards, will drive the cylindrical shell 55, solenoid valves 58, and hollow rubber ball 59 downwards. The cylindrical shell 55 pulls the spring 56, causing it to deform. The elastic deformation of spring 56 generates tension, causing the inner column 53 to maintain a downward trend. This causes the inner column 53 to drive the double fixing plate 51 and pressure roller 52 to press down on the profile body 16, improving the stability of fixing the profile body 16. Since the rubber sealing ring 54 seals the inner column 53 and the cylindrical shell 55, the hydraulic oil inside the cylindrical shell 55 will enter the rubber hollow ball 59 through the oil passage 57 and the solenoid valve 58. After the solenoid valve 58 is closed, it will achieve the effect of positioning the inner column 53 and the cylindrical shell 55, thereby fixing the profile body 16. This fixing method can fix profile bodies 16 of various diameters at the same time, and significantly reduces the phenomenon of deformation of the profile body 16 caused by improper fixing force. During the cutting and sorting of profile bodies 16, the position of the laser cutting machine 35 is controlled by the linear module 34. The laser emitted by the laser cutting machine 35 cuts the profile bodies 16. After all profile bodies 16 are cut, the existing controller controls multiple solenoid valves 58 to open simultaneously. At this time, the first electric hydraulic cylinder 22 drives the push plate 23, the shaft seat 24, and the arc roller 25 to move downward. The second electric hydraulic cylinder 32 controls the guide plate 41 and multiple fixing components 5 to move downward simultaneously. During the movement, the elastic tension of the spring 56 keeps the pressure roller 52 in contact with the profile body 16, which can prevent the profile body from being cut. The profile body 16 is detached until the top of the arc roller 25 is aligned with the bottom of the receiving groove 17. Multiple solenoid valves 58 are closed to position the built-in column 53 and the cylindrical shell 55. The second electric hydraulic cylinder 32 is controlled to move multiple fixing components 5 away from the profile body 16. The cut profile body 16 is pushed into the receiving groove 17 by the pushing mechanism, thus completing the sorting purpose. This cutting and sorting method requires the staff to transport the profile body 16 separately, which gradually reduces the damage caused by collision during the transportation process and significantly improves the processing efficiency, making it suitable for large-scale profile body 16 processing operations.

The profile bodies (16) enter between the arc roller (25) and the pressure roller (52). The top of the arc roller (25) is flush with the top of the load-bearing roller (15). After the profile bodies (16) move to the right, they come into contact with the arc roller (25). The arc roller (25) rotates due to friction. The position of the profile body (16) to be cut is aligned with the cutting range of the laser cutting machine (35). Step 2: When fixing multiple profile bodies (16), multiple solenoid valves (58) are open, the elastic tension of springs (56) is applied, most of the built-in columns (53) are located outside the cylinder shell (55), the double fixing plates (51) are far away from the cylinder shell (55), and most of the hydraulic oil inside the rubber hollow ball (59) is concentrated inside the cylinder shell (55). The second electric hydraulic cylinder (32) is started to push the extension frame (33) and guide plate (41) to move downward. The guide plate (41) simultaneously drives multiple fixing components (5) to move downward. The sliding groove (44) slides on the outside of the guide column (26), and the bottom end of the pressure roller (52) is aligned with its corresponding profile. The top of the material body (16) is attached. When the guide plate (41) moves downward, it will drive the cylinder shell (55), solenoid valve (58) and rubber hollow ball (59) to move downward. The cylinder shell (55) pulls the spring (56) to deform. The built-in column (53) maintains the downward trend. The built-in column (53) drives the double fixed plate (51) and pressure roller (52) to squeeze the profile body (16) downward. The rubber sealing ring (54) seals the built-in column (53) and cylinder shell (55). The hydraulic oil inside the cylinder shell (55) enters the rubber hollow ball (59) through the oil passage (57) and solenoid valve (58). The solenoid valve (58) closes. Step 3: During the cutting and sorting of the profile body (16), the linear module (34) controls the position of the laser cutting machine (35). The laser emitted by the laser cutting machine (35) cuts the profile body (16). After the profile body (16) is cut, multiple solenoid valves (58) open simultaneously, controlling the first electric hydraulic cylinder (22) to drive the push plate (23), the bearing seat (24) and the arc roller (25) to move downward. The second electric hydraulic cylinder (32) controls the guide plate (41) and multiple fixed The fixed component (5) moves downwards simultaneously, and the elastic tension of the spring (56) keeps the pressure roller (52) in contact with the profile body (16). The top of the arc roller (25) is aligned with the bottom of the receiving groove (17). Multiple solenoid valves (58) are closed to position the built-in column (53) and the cylinder shell (55). The second electric hydraulic cylinder (32) is controlled to move multiple fixed components (5) away from the profile body (16). The pushing mechanism pushes the cut profile body (16) into the receiving groove (17).
