Description

Technical Field

[0001] The present invention relates to the technical field of extrusion molding devices, and in particular to a graphite electrode extrusion molding device and method. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made from petroleum coke and asphalt coke as aggregates and coal tar as binder, through raw material calcination, crushing and grinding, batching, mixing, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode to distinguish it from natural graphite electrode made from natural graphite as raw material.

[0003] The patent application with reference publication number CN219214203U discloses a forming mold for graphite electrode processing, comprising a base, the top of the base is rotatably connected to a support column, the top of the support column is fixedly connected to a top plate, the bottom of the top plate is fixedly installed with a cylinder, the driving end of the cylinder is fixedly connected to a pressure plate, and a mold barrel fixedly connected to the top of the base is provided below the pressure plate, and a groove is provided on the top of the base. The graphite electrode raw material is placed in the mold barrel, and the driving end of the cylinder drives the pressure plate into the mold barrel. Under the extrusion of the pressure plate and the push plate, the graphite electrode is extruded and formed. The pressure plate is squeezed downward and the push plate is forced to move downward. After the extrusion is completed, the driving end of the cylinder contracts and drives the pressure plate to move to the outside of the mold barrel, and the output shaft of the motor rotates to drive the pressure plate to move away from the top of the mold barrel. At the same time, when the pressure plate moves away from the inside of the mold barrel, the spring resets and drives the push plate to push the formed graphite electrode upward, so that the graphite electrode can be taken out.

[0004] In the above scheme, the graphite electrode raw material is extruded and formed, and the graphite electrode is hollow and cylindrical. Therefore, when the upper pressing part contacts the inner wall of the mold, lubricant is often required. For the lubrication of the inner wall, the conventional lubrication system adopts a fixed flow pumping method, which cannot dynamically adjust the amount of lubricant according to the contact area, resulting in excessive waste or uneven lubrication, affecting the life of the mold and molding accuracy. Existing mold cleaning mostly adopts a single mechanical scraping or air blowing method, which has an insufficient removal rate for high-viscosity residues (such as the release agent polymer layer) and is easy to damage the mold surface. In addition, the internal space is limited. It is difficult for traditional robotic arms to achieve multi-degree-of-freedom precise coordination in a limited space.

[0005] Therefore, it is necessary to provide a graphite electrode extrusion molding device and method to solve the above technical problems. Summary of the Invention

When the electric push rod pushes the extrusion plate to form a sealed cavity, the air pump inputs 0.3-0.6MPa compressed air through the tube and sprays it from one side of the flexible metal strip through the groove to achieve the peeling of the adhesion by the air flow. The heating equipment can be set to heat the gas to 80-120℃, which can significantly reduce the adhesion of high-viscosity residues. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] like Figures 1 to 13 As shown, a graphite electrode extrusion molding device and method include the following embodiments: Embodiment 1: includes a processing frame 1, the top of the processing frame 1 is fixedly connected to a support frame 2, a lower pressing member 203 for extrusion is provided inside the support frame 2, and a pushing member for pressing the lower pressing member 203 downward is provided inside the support frame 2, the pushing member includes a lower pressing plate 201 slidably connected to the inside of the support frame 2, the lower pressing member 203 is fixedly connected to the bottom of the lower pressing plate 201, and a first hydraulic rod 202 is fixedly connected to the top of the support frame 2, and the telescopic end of the first hydraulic rod 202 is fixedly connected to the lower pressing plate 201, and further includes: A sliding seat 3 is provided inside the processing frame 1, and two molds 4 are fixedly connected to the top of the sliding seat 3. Both molds 4 are provided with ejection mechanisms; A rotating disk 5 is rotatably connected to the top of the processing rack 1. Two movable frames 6 are provided on the top of the rotating disk 5. A cleaning brush 611 is fixedly connected to the top of the movable frame 6. Lubricating components for lubricating the inner wall of the lower pressing piece 203 are provided inside the two movable frames 6. Storage boxes 7 for storing lubricants are provided on both sides of the movable frames 6. The storage boxes 7 are fixedly connected to the top of the rotating disk 5. A transmission member is provided between the rotating disk 5 and the movable frame 6. When the rotating disk 5 rotates, the movable frame 6 is pulled out from under the lower pressing piece 203 through the transmission member. Two gear rings 8 are rotatably connected to the top of the processing frame 1, and two third hydraulic rods 803 are fixedly connected to the bottom of the two gear rings 8. The outer side of the gear ring 8 is meshed with the fifth gear 801, and the telescopic ends of the third hydraulic rods 803 are fixedly connected to the cleaning frame 9. A cleaning mechanism for cleaning the inner wall of the mold 4 is provided inside the cleaning frame 9.

[0027] In a specific implementation, when the inside of the mold 4 is filled, the mold 4 is moved to the bottom of the lower pressing piece 203 by the driving module 301 after filling, and the lower pressing piece 203 is pushed down by the pushing piece so that the lower pressing piece 203 squeezes the material inside the mold 4 into shape. When the lower pressing piece 203 is lowered into the inside of the mold 4, it is lowered to the top of the moving frame 6 through the lower pressing piece 203 and contacts with the cleaning brush 611. At this time, the inner wall of the lower pressing piece 203 is lubricated by the lubricating component on the moving frame 6, and the rotating disk 5 is driven to rotate by the transmission member, and the moving frame 6 is driven to continuously move from the bottom The pressing piece 203 is moved away from the bottom. When the mold 4 moves to one side through the sliding seat 3, the graphite electrode formed inside the mold 4 is ejected by the ejection mechanism inside the mold 4, and the graphite electrode is pushed out by the external pushing device. When the ejection mechanism is reset, the cleaning frame 9 is pushed by the third hydraulic rod 803 on the gear ring 8 to move the cleaning frame 9 to the upper part of the mold 4, and then the inner wall of the mold 4 is cleaned by the cleaning component on the cleaning frame 9, thereby ensuring that the mold 4 is in the best condition each time extrusion molding is performed to avoid residue affecting the surface of the graphite electrode.

[0028] Embodiment 2: The lubrication assembly includes a slide 601, which is slidably connected to the inside of the moving frame 6, and a lifting plate 602 is provided on the top of the slide 601, and a telescopic rod 604 is fixedly connected between the lifting plate 602 and the slide 601, and a smear plate 603 is fixedly connected to the top of the lifting plate 602, and a first nozzle is provided inside the smear plate 603, and limiting rods 609 are fixedly connected on both sides of the lifting plate 602, and limiting grooves 600 are provided on both sides of the moving frame 6. The limiting grooves 600 adopt an involute design, so that the smear plate 603 can synchronously complete the lifting action during radial movement, ensuring that the lubricant automatically disengages after full coverage, and the limiting rod 609 extends to the inside of the limiting groove 600 and is slidably connected to the moving frame 6. When the lifting plate 602 is at one end of the moving frame 6, the top of the smear plate 603 is flush with the top of the moving frame 6.

[0029] The lubrication assembly also includes a magnetic plate 605 and a fixed plate 607 fixedly connected to the top of the slide 601. An electromagnet plate 612 is fixedly connected to one end of the movable frame 6. A foldable capsule 606 is fixedly connected between the magnetic plate 605 and the electromagnet plate 612. A connecting pipe 610 is fixedly connected between the foldable capsule 606 and the storage box 7. A drainage pipe is provided between the foldable capsule 606 and the first nozzle. After the electromagnet plate 612 is energized, the magnetic repulsion force pushes the magnetic plate 605 to move, causing the smear plate 603 to extend out of the movable frame 6 and contact the inner wall of the pressing piece 203. At the same time, the foldable capsule 606 extracts lubricant in a quantitative manner through the connecting pipe 610. A spring 608 is fixedly connected between the fixed plate 607 and the other end of the movable frame 6.

[0030] During specific implementation, when the pressing member 203 contacts the inner wall of the mold 4, the graphite electrode is in the shape of a hollow circle, so the pressing member 203 is annular, and the inner wall and the outer part of the pressing member 203 are in contact with the mold 4. During the contact process, the friction of the contact part is often the largest, so it is necessary to spray lubricant on the outer side of the pressing member 203. The inner wall of the pressing member 203 is often not convenient to spray. Therefore, in this solution, before each extrusion, the pressing member 203 is driven to lower the pressing member 203 so that the bottom of the pressing member 203 contacts the cleaning brush 611 at the top of the two moving frames 6, and then the electromagnetic plate 612 is started. When the electromagnetic plate 612 is energized, the electromagnetic repulsion force pushes the magnetic plate 605 on the top of the slide 601 away from the electromagnetic plate 612, and the lifting plate 602 is fixedly connected to the slide 601 through the telescopic rod 604. When the slide 601 moves, it drives the lifting member 605 to move downward. The lowering plate 602 moves together, and the limiting rods 609 on both sides of the lifting plate 602 move in the limiting grooves 600 provided on the outer side of the moving frame 6. At this time, the smear plate 603 on the top of the lifting plate 602 contacts the inner wall of the pressing piece 203. After the contact, the pressing piece 203 cannot move. The foldable capsule 606 is fixedly connected between the magnetic plate 605 and the electromagnet plate 612 and is stretched during the movement. The lubricant inside the storage box 7 is sucked into the foldable capsule 606 through the connecting pipe 610. The spraying amount is automatically quantitatively determined according to the contact position between the smear plate 603 and the lifting plate 602. For example, when the smear plate 603 moves a short distance, it means that the area of ​​the inner wall of the pressing piece 203 that needs to be lubricated is small, and the amount of lubricant extracted by the foldable capsule 606 is automatically reduced for automatic adaptation. If the lifting plate 602 moves a long distance, on the contrary, it can be automatically quantitatively lubricated. When the transmission member drives the movable frame 6 to move, the smear plate 603 contacts the inner wall of the lower pressing member 203, so the smear plate 603 moves relative to the movable frame 6. At this time, the magnetic plate 605 will squeeze the foldable capsule 606 between the electromagnetic plates 612, and the lubricant inside the foldable capsule 606 will be sprayed on the inner wall of the lower pressing member 203 through the first nozzle and the first drainage pipe, and evenly spread through the smear plate 603.

[0031] The slide 601 is driven to move by the repulsive force between the electromagnet plate 612 and the magnetic plate 605, and the foldable capsule 606 automatically adjusts the amount of lubricant extracted according to the displacement, thereby achieving dynamic matching of the contact area and the amount of lubricant used. The cooperation between the limiting rod 609 and the limiting groove 600 ensures the accurate movement trajectory of the lifting plate 602, so that the smear plate 603 and the inner wall of the lower pressure piece 203 maintain a constant contact pressure.

[0032] In this embodiment, connecting plates 510 are fixedly connected on both sides of the movable frame 6, and a support seat 511 is slidably connected to the outside of the connecting plate 510, and the support seat 511 is fixedly connected to the top of the rotating disk 5, and a second nozzle 701 is fixedly connected to the top of the support seat 511. A micro pump 702 is provided between the storage box 7 and the second nozzle 701, which is used to spray the lubricant inside the storage box 7 through the second nozzle 701.

[0033] The transmission member includes a second gear ring 501 fixedly connected to the outside of the rotating disk 5, and the outside of the second gear ring 501 is meshed with a second gear 502. The top of the processing frame 1 is fixedly connected to the first motor, and the output shaft of the first motor is fixedly connected to the second gear 502. A third gear ring 503 is provided on the top of the rotating disk 5. The third gear ring 503 is fixedly connected to the processing frame 1 through a support plate 1, and the third gear 504 is meshed inside the third gear ring 503. The bottom of the third gear 504 is fixedly connected to a second pulley 509, and the second pulley 509 is fixedly connected to the rotating disk. 5 is rotatably connected, a rack is fixedly connected to the bottom of the movable frame 6, and a fourth gear 505 is meshedly connected to the bottom of the rack. A support plate is rotatably connected to the outer side of the fourth gear 505, and the second support plate is fixedly connected to the rotating disk 5. A first bevel gear 506 is fixedly connected to one side of the fourth gear 505, and a second bevel gear 507 is meshedly connected to the outer side of the first bevel gear 506. A first pulley 508 is fixedly connected to the bottom of the second bevel gear 507, and the first pulley 508 is rotatably connected to the rotating disk 5, and the second pulley 509 is connected to the first pulley 508 through a belt transmission.

[0034] In specific implementation, after the smear plate 603 in the above scheme contacts the inner wall of the lower pressing member 203, by starting the first motor, the output shaft of the first motor drives the second gear 502 to rotate, the second gear 502 drives the rotating disk 5 to rotate, and the rotation of the rotating disk 5 drives the third gear 504 to rotate together. At this time, the third gear 504 is engaged with the third gear ring 503, the third gear 504 rotates on its own, and the third gear 504 drives the second pulley 509 to rotate, and the second pulley 509 drives the first pulley 508 to rotate through the belt transmission. When the first pulley 508 drives the fourth gear 505 to rotate through the transmission of the second bevel gear 507 and the first bevel gear 506, the fourth gear 505 drives the rack at the bottom of the movable frame 6 to move, and the third gear 504 is engaged with the third gear ring 503. The movable frame 6 moves toward the outside of the rotating disk 5. At this time, the cleaning brush 611 on the top of the movable frame 6 rotates and cleans the bottom of the lower pressing piece 203, and continues to move away from the center of the circle of the lower pressing piece 203. The smear plate 603 inside the movable frame 6 also continues to move along the trajectory of the limiting groove 600 along the limiting rod 609. Finally, the smear plate 603 drops to the inside of the movable frame 6 and no longer contacts the lower pressing piece 203, thereby achieving lubrication of the inner wall of the lower pressing piece 203. A second nozzle 701 is provided on the top of the support seat 511. The lubricant inside the storage box 7 is continuously sprayed out through the second nozzle 701 through the micro pump 702 to lubricate a circle outside the lower pressing piece 203, and the inside and outside of the lower pressing piece 203 are lubricated synchronously.

[0035] The contact lubrication of the inner smear plate 603 complements the non-contact injection of the outer nozzle 701. The micro pump 702 is equipped with a flow sensor, which dynamically adjusts the injection pressure by 0.2-0.5MPa according to the displacement of the moving frame. The rotation speed of the cleaning brush 611 maintains a 1:3 ratio with the moving speed to achieve efficient debris removal.

[0036] Embodiment 3: The ejection mechanism includes an ejection plate 401, and the inner and outer sides of the ejection plate 401 are rotatably sleeved with electromagnet rings 402, and the bottoms of the two electromagnet rings 402 are fixedly connected to the first gear ring 403, and the outer sides of the first gear rings 403 are meshed with the first gear 405, and the bottom of the ejection plate 401 is fixedly connected to the second motor 406, and the output shaft of the second motor 406 is fixedly connected to the first gear 405, and a second hydraulic rod 404 is fixedly connected between the ejection plate 401 and the bottom end of the mold 4. The two electromagnet rings 402 generate magnetism when energized.

[0037] In specific implementation, when the graphite electrode is formed, the second hydraulic rod 404 is started, and the second hydraulic rod 404 drives the ejection plate 401 to rise, ejecting the graphite electrode from the mold 4 and rising to the top of the processing rack 1. At this time, the graphite electrode is pushed to the next link by an external pushing device.

[0038] In this embodiment, the cleaning mechanism includes two movable seats 901, one of which is fixedly connected to one end of the cleaning frame 9, and the other is slidably connected to the cleaning frame 9. A horizontal module 902 is provided inside the cleaning frame 9 for driving the movable seat 901 to slide, and the bottoms of the two movable seats 901 are fixedly connected to a mounting frame 1001, and the interiors of the two mounting frames 1001 are rotatably connected to a winding roller 1002, and a cleaning tube 1003 is wrapped around the outside of the winding roller 1002. One end of the cleaning tube 1003 is fixedly connected to the outside of the mounting frame 1001, and the other end is fixedly connected to a metal plate 1004. A micro motor is fixedly connected to the outside of the mounting frame 1001, and the output shaft of the micro motor is fixedly connected to the winding roller 1002.

[0039] A plurality of exhaust holes 10031 are opened on the outside of the cleaning tube 1003 , and a flexible metal strip 10032 is fixedly connected to the outside of the cleaning tube 1003 . When the metal plate 1004 is magnetically attracted to the electromagnet ring 402 , the flexible metal strip 10032 is magnetically attracted to the inner wall of the mold 4 .

[0040] During specific implementation, when the graphite electrode inside the mold 4 needs to be ejected, the ejection mechanism is reset. At this time, there will be residues on the inner wall of the mold 4. In this solution, the third hydraulic rod 803 is started, and the third hydraulic rod 803 drives the cleaning frame 9 to move to the middle of the mold 4. At this time, the movable seat 901 fixed inside the cleaning frame 9 is at the innermost side of the mold 4, and the other movable seat 901 is moved to the upper part of the inner wall of the mold 4 through the horizontal module 902. At this time, the micro motor is started, and the micro motor drives the mounting frame 1001 to lower the cleaning tube 1003 wrapped around the outside, and the bottom end of the cleaning tube 1003 is fixedly connected to a metal plate 1004, which ensures that the cleaning tube 1003 is vertically lowered by the metal plate 1004. At this time, the electromagnet ring 402 in the ejection mechanism is energized to adsorb the metal plate 1004. At this time, the cleaning The tube 1003 contacts the inner wall of the mold 4. When the metal plate 1004 is magnetically attracted to the electromagnet ring 402, the flexible metal strip 10032 arranged on the outside of the cleaning tube 1003 is also made of metal material, so it will have a certain magnetic effect. At this time, the flexible metal strip 10032 is adsorbed and tightly adhered to the inner wall of the mold 4. Then, by starting the third motor 802, the third motor 802 drives the fifth gear 801 to rotate, and then the fifth gear 801 drives the gear ring 8 to rotate. At the same time, the second motor 406 drives the first gear 405 to rotate. The first gear 405 rotates through the meshing connection of the first gear ring 403, and the first gear ring 403 drives the electromagnet ring 402 to rotate, ensuring that the cleaning tube 1003 is in a fit state with the inner wall of the mold 4, and cleans the inner wall of the mold 4 along the inner wall of the mold 4, thereby improving the cleaning effect of the mold 4.

[0041] It is worth noting that the third motor 802 drives the gear ring 8 to rotate through the fifth gear 801, while the second motor 406 drives the electromagnet ring 402 to rotate through the first gear 405, forming a composite motion trajectory to ensure that the cleaning tube 1003 is in full contact with the inner wall of the mold. The flexible metal strip 10032 generates an adsorption force of 5-8N / cm² under a magnetic field strength of 0.5-1.2T, which not only ensures the fit but also avoids scratching the mold.

[0042] In this embodiment, the bottom of the mounting frame 1001 is fixedly connected to a lower mounting plate 11, and a connecting ring 113 is fixedly connected to the inside of the lower mounting plate 11. The cleaning tube 1003 passes through the connecting ring 113, and a through groove 114 is provided on the inner side of the connecting ring 113. The through groove 114 is connected to the exhaust hole 10031 provided on the outer side of the cleaning tube 1003. An air pump 116 is fixedly connected to the outer side of the lower mounting plate 11, and a through pipe 115 is fixedly connected between the air delivery end of the air pump 116 and the inside of the connecting ring 113. An electric push rod 111 is fixedly connected to the inside of the lower mounting plate 11, and the telescopic end of the electric push rod 111 is fixedly connected to an extrusion plate 112. The extrusion plate 112 extrude and seals the cleaning tube 1003.

[0043] In the specific implementation, after the cleaning tube 1003 is fitted with the inner wall of the mold 4, the electric push rod 111 on the lower mounting plate 11 is started, and the electric push rod 111 pushes the extrusion plate 112 to seal one end of the cleaning tube 1003. The cleaning tube 1003 passes through the connecting ring 113 and is inflated through the through pipe 115 connected to the air outlet end of the air pump 116. The connecting ring 113 is connected to the flexible outer surface of the cleaning tube 1003 through the through groove 114 opened on the inner side. The exhaust holes 10031 are connected, so that the gas extends to the cleaning pipe 1003 to continuously blow air to the inner wall of the mold 4. When the electric push rod 111 pushes the extrusion plate 112 to form a sealed cavity, the air pump 116 inputs 0.3-0.6MPa compressed air through the through pipe 115, and sprays it from one side of the flexible metal strip 10032 through the through groove 114, thereby realizing the air flow to peel off the adhesion. A heating device can be set to heat the gas to 80-120℃, which significantly reduces the adhesion of high-viscosity residues.

[0044] A method for extruding a graphite electrode, comprising the following steps: Step 1: After the mold 4 is filled, the mold 4 is moved to the bottom of the lower pressing member 203 by the driving module 301, and the lower pressing member 203 is pushed down by the pushing member, so that the lower pressing member 203 squeezes the material inside the mold 4 into shape; Step 2: When the lower pressing member 203 descends into the mold 4, it descends to the top of the movable frame 6 and contacts the cleaning brush 611. At this time, the lubrication component on the movable frame 6 lubricates the inner wall of the lower pressing member 203, and the transmission member drives the rotating disk 5 to rotate, while driving the movable frame 6 to continuously move away from under the lower pressing member 203. Step 3: When the mold 4 moves to one side through the sliding seat 3, the graphite electrode formed inside the mold 4 is ejected by the ejection mechanism inside the mold 4, and the graphite electrode is pushed out by the external pushing device; Step 4: After the ejection mechanism is reset, the cleaning frame 9 is pushed by the third hydraulic rod 803 on the gear ring 8 to move the cleaning frame 9 to the upper part of the mold 4, and then the cleaning assembly on the cleaning frame 9 is used to clean the inner wall of the mold 4.
