Technical Field
[0001] This invention relates to the field of punching technology, specifically to a punching press for processing aluminum alloy door panels. Background Technology
[0002] Aluminum alloys possess advantages such as light weight, high strength, corrosion resistance, and ease of processing, making them widely used in door panel manufacturing in construction and home furnishing industries. Aluminum alloy door panels not only meet the aesthetic requirements of buildings but also offer excellent performance characteristics, such as sound insulation, heat insulation, and waterproofing. As people's demands for quality of life and architectural decoration continue to rise, higher requirements are being placed on the precision, surface quality, and production efficiency of aluminum alloy door panels. The punch press is one of the key pieces of equipment in the aluminum alloy door panel processing. It applies enormous pressure and uses molds to stamp aluminum alloy sheets, achieving processes such as cutting, punching, and forming of the door panels. The processing precision, speed, and stability of the punch press directly affect the quality and production efficiency of the aluminum alloy door panels.
[0003] When the existing punch press is working, the door panel may slide or shift due to vibration, inertia or other reasons during the process of moving to the designated position. This may cause the door panel to be unable to be accurately positioned on the punch press during the conveying process, resulting in punching deviation and thus producing defective products due to inaccurate positioning. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a door panel punching machine for processing aluminum alloy door panels, including a support block, a top plate fixedly connected to the top of the support block, a hydraulic cylinder fixedly connected to the top of the top plate, and a moving groove opened on the outer side of the support block. A conveying assembly is located on the side of the support block near the top plate; The stamping assembly is fixedly connected to the output end of the hydraulic cylinder and slidably connected to the inner wall of the moving groove. A fixing component is located below the conveying component, and a collection box is fixedly connected to the side of the fixing component; The fixing components include a platform, a fixing rod slidably connected to the top of the platform, a fixing plate fixedly connected to the top of the fixing rod, an electric actuator fixedly connected to the top of the platform, the output end of the electric actuator fixedly connected to the bottom of the fixing plate, and a fixing frame fixedly connected to the top of the fixing plate. There are multiple fixing rods evenly distributed at the top corners of the platform, and multiple fixing frames evenly distributed on the fixing plate. When a door panel is placed on top of the roller, the motor, powered by an external power source, rotates the shaft, which in turn rotates the roller, moving the top door panel to the desired processing position. Subsequently, the electric actuator pushes the fixing plate. Moving along the direction of the fixed rod, the fixed plate causes the top fixed frame to pass through the gap between the rollers and extend to the top of the rollers. This allows the fixed block at the top of the fixed frame to lift the door panel off the roller surface, detaching the door panel from contact with the roller. This allows for better positioning of the door panel during the stamping process and avoids interference from the rollers on the stamping area of the door panel. The top of the fixed plate has a circular groove, which is alternately arranged with the fixed frame. The top of the fixed plate also has a circular hole. A fixed cylinder is fixedly connected to the inner wall of the fixed frame, and the fixed cylinder and the circular hole are located on the same vertical plane. A fixed block is slidably connected to the inner wall of the fixed frame. The rollers are responsible for the movement of the door panel during normal conveying, while the fixed... After the block lifts the door panel, the roller can be repositioned or switched. When the block descends again and the door panel falls back onto the roller, the roller can transport the door panel to the next processing station, enabling continuous and efficient processing of the door panel on the punch press. This makes the entire processing process more orderly and stable, improving production efficiency. The top of the block has multiple grooves evenly distributed across it. A cylinder is fixedly connected to the side of the block closest to the fixed cylinder, with the fixed cylinder fitted over the outer side of the cylinder. A compression spring is fixedly connected to the inner wall of the fixed frame, fitted over the outer side of the fixed cylinder. The end of the compression spring furthest from the fixed frame is fixedly connected to the block. The circular hole... The fixed cylinder and the cylindrical cylinder overlap vertically. A guide frame is fixedly connected to the bottom of the fixed plate. Under the pressure of the pressure head, the waste material is detached from the door panel and enters the inside of the cylindrical cylinder. Then, the waste material passes through the fixed cylinder and the cylindrical cylinder and enters the inside of the guide frame. Since the guide frame is set at an angle, the waste material moves along the guide frame and falls into the inside of the collection box under the action of gravity. Timely collection of waste material can prevent waste material from being piled up randomly in the workshop, making the working environment cleaner and more orderly. This is conducive to improving the work efficiency and enthusiasm of employees, and can also reduce the safety hazards caused by waste material accumulation, such as tripping and slipping accidents. The guide frame is located below the circular hole. Preferably, the conveying assembly includes a frame, with side plates fixedly connected to the top of the frame. A rotating shaft is rotatably connected to the outer side of each side plate, and rollers are fixedly connected to the outer side of the rotating shaft. Multiple rollers are present, with a fixed frame located at the interval between adjacent rollers. There are two side plates symmetrically arranged on the top of the frame. Both ends of the rotating shaft are rotatably connected to the opposite sides of the two side plates. A drive belt is rotatably connected to the outer side of the rotating shaft. Multiple rotating shafts are connected via the drive belt. A motor is fixedly connected to the outer side of each side plate. The motor's output end passes through the side plate and extends to the interval between the two side plates. The motor's output end is fixedly connected to the rotating shaft. A positioning block is fixedly connected to the opposite side of each side plate, and a connecting plate is fixedly connected to the top of each side plate near the positioning block. When a door panel is placed on the rollers, the motor, powered by an external power source, operates. The motor drives the rotating shaft to rotate, which in turn drives the rollers to rotate, causing the rollers to move the door panel. At this point, the door panel contacts and is squeezed by the rotating plates on both sides. Under the elastic force of the arc plate, the rotating plate drives the cylinder to slide on the inner wall of the annular groove, so that the roller on the outer side of the rotating plate is in close contact with the door panel. By setting the rotating plates on both sides, the door panel can be located in the middle of the roller, so that the door panel is conveyed according to a specific path, which plays a guiding and transition role, helps to improve the accuracy of door panel conveying, ensures that the door panel enters the designated position accurately, thereby improving the accuracy and consistency of stamping processing, and reducing the scrap rate caused by door panel position deviation. The top of the connecting plate is provided with an annular groove. The side of the positioning block near the connecting plate is rotatably connected to the rotating plate. The top of the rotating plate away from the positioning block is fixedly connected to a cylinder, which is located on the inner wall of the annular groove. The side of the rotating plate away from the positioning block is fixedly connected to an arc plate. The arc plate is elastic. The side of the arc plate away from the rotating plate is fixedly connected to the side plate. The outer side of the rotating plate is rotatably connected to a roller.
[0005] Preferably, the stamping assembly includes guide pillars, and there are multiple guide pillars. The multiple guide pillars are slidably connected to the top plate. A square plate is fixedly connected to the bottom of the guide pillars. A hydraulic cylinder is fixedly connected to the top middle of the square plate. A slider is fixedly connected to one end of the square plate near the support block. The slider is slidably connected to the moving groove. A stamping part is fixedly connected to the bottom of the square plate. An adjusting part is fixedly connected to the outside of the stamping part.
[0006] Preferably, the stamped part includes a connecting block, which is fixedly connected to the square plate. A cylinder is fixedly connected to the bottom of the connecting block. A sliding groove is provided on the outer side of the cylinder. A protective cylinder is slidably connected to the outer side of the sliding groove. A through hole is provided in the middle of the bottom of the protective cylinder. A sliding groove is provided on the inner wall of the cylinder. A ring block is slidably connected to the inner wall of the cylinder. A protrusion is provided on the outer side of the ring block. When the door panel moves to a designated position, the hydraulic cylinder works to drive the square plate to move downward. The square plate drives the slider to move inside the moving groove, so that the square plate drives the bottom cylinder and the protective cylinder to move downward, so that the bottom of the protective cylinder contacts the door panel. The hydraulic cylinder drives the square plate to continue moving downwards. The protective cylinder moves towards the connecting block inside the sliding groove, causing the pressure head on the cylinder to press against the door panel. The ring block slides against the inner wall of the cylinder through the cooperation between the protrusion and the sliding groove. The pressure head is installed inside the ring block and is threadedly connected to the ring block. During the operation of the punch press, the pressure head needs to withstand a large impact force and pressure. Because the threaded connection between the pressure head and the ring block can provide a large axial force, it tightly connects the pressure head with other parts of the ring block, ensuring that the pressure head will not easily loosen or fall off, thus guaranteeing the operation of the punch press. The system ensures stability and safety. The threaded connection between the pressure head and the ring block allows for easy installation and removal of the pressure head. This facilitates rapid operation when the pressure head wears out, is damaged, or needs to be replaced with a different specification, reducing downtime and improving production efficiency. The pressure head penetrates the cylinder and extends into the protective cylinder. A slot is formed on the outer side of the pressure head, and multiple intermediate plates are fixedly connected to the inner wall of the slot. A return spring is fixedly connected to the top of the ring block. The hydraulic cylinder moves the pressure head downwards through the cylinder. This causes the pressure head to contact the door panel, compressing the return spring and causing the pressure head to slide the ring block inside the groove. By setting the return spring and compression spring, the pressure head can maintain a relatively stable pressure during the stamping process, which helps to improve the stamping accuracy and surface quality of the door panel, and reduce stamping defects caused by uneven pressure. At the same time, the return spring and compression spring act as a buffer, reducing damage to the pressure head, door panel and other parts of the punch press, extending service life, and preventing the door panel from deforming or being damaged due to excessive impact force. The end of the return spring away from the ring block is fixedly connected to the square plate.
[0007] Preferably, the adjusting component includes a pressure plate, with multiple guide rods fixedly connected to the top of the pressure plate. These guide rods are evenly distributed at the top corners of the pressure plate and are slidably connected to the top plate. A through groove is formed in the top of the pressure plate. When the hydraulic cylinder operates, it drives a square plate downwards, which in turn drives the bottom pressure plate downwards, bringing the pressure plate into contact with the top of the door panel. At this time, an externally powered electric motor operates, driving a rotating rod to rotate. As the rotating rod rotates, it causes the connecting rods and clamping blocks at both ends to move along the inner wall of the through groove towards the rotating rod, thus limiting the door panel's movement in the conveying direction using the clamping blocks on both sides. Through its cooperation with the rotating plate, the door panel is positioned in the center of the designated location, ensuring that the hole position matches the design requirements and avoiding deviations that could cause the door panel size to be non-compliant with specifications, thereby improving the product qualification rate. A round rod is fixedly connected inside the through groove, and a support plate is fixedly connected to the outside of the protective cylinder. A motor is fixedly connected to the bottom of the support plate, and a rotating rod is fixedly connected to the output end of the motor. The rotating rod is rotatably connected to the top of the pressure plate. The through groove is symmetrically arranged with the rotating rod as the center. A connecting rod is rotatably connected to the end of the rotating rod, and a clamping block is rotatably connected to the end of the connecting rod away from the rotating rod. The clamping block is located on the inner wall of the through groove, and the round rod passes through the clamping block.
[0008] This invention provides a door panel punching press for processing aluminum alloy door panels. It has the following beneficial effects: 1. The door panel punching machine for processing aluminum alloy door panels can lift the door panel from the roller surface by fixing the top of the fixed frame, so that the door panel is no longer in contact with the roller. This allows for better positioning of the door panel during the punching process, avoids interference from the roller on the door panel punching area, and can transport the door panel to the next processing station. This enables continuous and efficient processing of the door panel on the punching machine, making the entire processing process more orderly and stable, and improving production efficiency.
[0009] Second, the door panel punching machine for processing aluminum alloy door panels uses an inclined guide frame, which allows the waste material to move along the guide frame and fall into the collection box under the action of gravity. Timely collection of waste material can prevent waste material from being piled up randomly in the workshop, making the working environment cleaner and more orderly. This is conducive to improving the work efficiency and enthusiasm of employees, and can also reduce the safety hazards caused by waste material accumulation.
[0010] Third, the door panel punching machine for processing aluminum alloy door panels, by setting rotating plates on both sides, can position the door panel in the middle of the roller, so that the door panel is conveyed along a specific path, playing a guiding and transition role, which helps to improve the accuracy of door panel conveying, ensures that the door panel enters the designated position accurately, thereby improving the accuracy and consistency of stamping processing, and reducing the scrap rate caused by door panel position deviation.
[0011] Fourth, the door panel punching machine for processing aluminum alloy door panels can realize the installation and disassembly of the press head through the threaded connection between the press head and the ring block. This is beneficial to quickly complete the relevant operations when the press head is worn, damaged, or needs to be replaced with a press head of different specifications, thereby reducing equipment downtime and improving production efficiency.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0015] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a door panel punching machine for processing aluminum alloy door panels, including a support block 3, a top plate 8 fixedly connected to the top of the support block 3, a hydraulic cylinder 4 fixedly connected to the top of the top plate 8, and a moving groove 7 opened on the outer side of the support block 3. Conveying assembly 1 is disposed on the side of support block 3 near top plate 8; The stamping assembly 5 is fixedly connected to the output end of the hydraulic cylinder 4, and the stamping assembly 5 is slidably connected to the inner wall of the moving groove 7. Fixing component 2 is located below conveying component 1, and a collection box 6 is fixedly connected to the side of fixing component 2; The fixing component 2 includes a platform 21, with a fixing rod 22 slidably connected to the top of the platform 21. A fixing plate 24 is fixedly connected to the top of the fixing rod 22, and an electric push rod 23 is fixedly connected to the top of the platform 21. The output end of the electric push rod 23 is fixedly connected to the bottom of the fixing plate 24. A fixing frame 25 is fixedly connected to the top of the fixing plate 24. There are multiple fixing rods 22, which are evenly distributed at the top corners of the platform 21. There are also multiple fixing frames 25, which are evenly distributed on the fixing plate 24. When the door panel is placed on top of the roller 15, the motor 13, powered by an external power source, drives the rotating shaft 14 to rotate. The rotating shaft 14 then drives the roller 15 to rotate, causing the roller 15 to move the top door panel. The electric actuator 23 moves the fixed plate 24 to the position to be processed, and then pushes the fixed plate 24 to move along the direction of the fixed rod 22. This causes the fixed plate 24 to drive the top fixed frame 25 through the gap between the rollers 15 and extend to the top of the rollers 15. This allows the fixed block 29 at the top of the fixed frame 25 to lift the door panel from the surface of the rollers 15, so that the door panel is no longer in contact with the rollers 15. This allows for better positioning of the door panel during the stamping process and avoids interference from the rollers 15 on the stamping area of the door panel. The top of the fixed plate 24 has a circular groove 26, which is alternately arranged with the fixed frame 25. The top of the fixed plate 24 has a circular hole 28. The inner wall of the fixed frame 25 is fixedly connected to a fixed cylinder 212, which is located on the same vertical plane as the circular hole 28. On the surface, a fixing block 29 is slidably connected to the inner wall of the fixing frame 25. The roller 15 is responsible for the movement of the door panel during normal conveying. After the fixing block 29 lifts the door panel, the roller 15 can adjust or switch positions. When the fixing block 29 lowers again and the door panel falls back onto the roller 15, the roller 15 can transport the door panel to the next processing station, realizing continuous and efficient processing of the door panel on the punch press, making the entire processing process more orderly and stable, and improving production efficiency. The top of the fixing block 29 is provided with a groove 211. There are multiple grooves 211, which are evenly distributed on the fixing block 29. A cylinder 210 is fixedly connected to the side of the fixing block 29 near the fixing cylinder 212. The fixing cylinder 212 is sleeved on the outside of the cylinder 210. A compression spring 213 is fixedly connected to the inner wall of the fixed frame 25. The compression spring 213 is sleeved on the outside of the fixed cylinder 212. The end of the compression spring 213 away from the fixed frame 25 is fixedly connected to the fixed block 29. The circular hole 28 coincides with the fixed cylinder 212 and the cylinder 210 in the vertical direction. A guide frame 27 is fixedly connected to the bottom of the fixed plate 24. Under the pressure of the pressure head 559, the waste material is detached from the door panel and enters the inside of the cylinder 210. Then, the waste material enters the inside of the guide frame 27 through the fixed cylinder 212 and the cylinder 210. Since the guide frame 27 is inclined, the waste material moves along the guide frame 27 and falls into the inside of the collection box 6 under the action of gravity. Timely collection of waste material can prevent waste material from being piled up randomly in the workshop.This makes the work environment cleaner and more orderly, which helps improve employee work efficiency and enthusiasm, and also reduces safety hazards caused by waste accumulation, such as tripping and slipping accidents. The guide frame 27 is located below the circular hole 28. The conveying assembly 1 includes a frame 11, with side plates 12 fixedly connected to the top of the frame 11. A rotating shaft 14 is rotatably connected to the outer side of the side plates 12, and rollers 15 are fixedly connected to the outer side of the rotating shaft 14. Multiple rollers 15 are present, and a fixing frame 25 is located at the interval between adjacent rollers 15. There are two side plates 12 symmetrically arranged on the top of the frame 11. The two ends of the rotating shaft 14 are rotatably connected to the opposite sides of the two side plates 12. A drive belt 16 is rotatably connected to the outer side of the rotating shaft 14. The multiple rotating shafts 14 are connected via... A drive belt 16 is connected to a motor 13 fixedly connected to the outer side of the side plate 12. The output end of the motor 13 passes through the side plate 12 and extends to the gap between the two side plates 12. The output end of the motor 13 is fixedly connected to the rotating shaft 14. A positioning block 112 is fixedly connected to the opposite side of the side plate 12. A connecting plate 17 is fixedly connected to the top of the side plate 12 near the positioning block 112. When the door panel is placed on the roller 15, the motor 13 is powered by an external power source. The operation of the motor 13 drives the rotating shaft 14 to rotate, which in turn drives the roller 15 to rotate, thus causing the roller 15 to move the door panel. As the plate moves, the door panel contacts and is compressed by the rotating plates 19 on both sides. Under the elastic force of the arc plate 113, the rotating plate 19 drives the cylinder 111 to slide on the inner wall of the annular groove 18, so that the roller 110 on the outer side of the rotating plate 19 is in close contact with the door panel. By setting the rotating plates 19 on both sides, the door panel can be positioned in the middle of the roller 15, so that the door panel is conveyed along a specific path, playing a guiding and transition role, which helps to improve the accuracy of door panel conveying, ensures that the door panel enters the designated position accurately, thereby improving the accuracy and consistency of stamping processing, and reducing... To reduce the scrap rate caused by door panel position deviation, the top of the connecting plate 17 is provided with an annular groove 18. The positioning block 112 is rotatably connected to the side of the connecting plate 17. A cylinder 111 is fixedly connected to the top of the end of the rotating plate 19 away from the positioning block 112. The cylinder 111 is located on the inner wall of the annular groove 18. An arc plate 113 is fixedly connected to the end of the rotating plate 19 away from the positioning block 112. The arc plate 113 is elastic. The end of the arc plate 113 away from the rotating plate 19 is fixedly connected to the side plate 12. A roller 110 is rotatably connected to the outer side of the rotating plate 19.
[0016] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8As shown, the stamping assembly 5 includes guide posts 51, and there are multiple guide posts 51. The multiple guide posts 51 are slidably connected to the top plate 8. A square plate 53 is fixedly connected to the bottom of the guide post 51. The top middle of the square plate 53 is fixedly connected to the hydraulic cylinder 4. A slider 52 is fixedly connected to one end of the square plate 53 near the support block 3. The slider 52 is slidably connected to the moving groove 7. A stamping part 55 is fixedly connected to the bottom of the square plate 53. An adjusting part 54 is fixedly connected to the outside of the stamping part 55.
[0017] The stamped part 55 includes a connecting block 551, which is fixedly connected to the square plate 53. A cylinder 552 is fixedly connected to the bottom of the connecting block 551. A sliding groove 554 is provided on the outer side of the cylinder 552. A protective cylinder 553 is slidably connected to the outer side of the sliding groove 554. A through hole 555 is provided in the middle of the bottom of the protective cylinder 553. A sliding groove 556 is provided on the inner wall of the cylinder 552. A ring block 557 is slidably connected to the inner wall of the cylinder 552. A protrusion is provided on the outer side of the ring block 557. When the door panel moves to the designated position, the hydraulic cylinder 4 works to drive the square plate 53 to move downward. The square plate 53 drives the slider 52 to move inside the moving groove 7, so that the square plate 53 drives the bottom cylinder 552 and the protective cylinder 553 to move downward, so that the bottom of the protective cylinder 553... Upon contact with the door panel, as the hydraulic cylinder 4 drives the square plate 53 to continue moving downwards, the protective cylinder 553 moves towards the connecting block 551 inside the sliding groove 554, causing the pressure head 559 on the cylinder 552 to press against the door panel. The ring block 557 is slidably connected to the inner wall of the cylinder 552 through the cooperation between the protrusion and the sliding groove 556. The pressure head 559 is installed inside the ring block 557 and is threadedly connected to the ring block 557. During the operation of the punch press, the pressure head 559 needs to withstand a large impact force and pressure. Since the threaded connection between the pressure head 559 and the ring block 557 can provide a large axial force, the pressure head 559 is tightly connected to the other parts of the ring block 557, ensuring that the pressure head 559 will not easily loosen or detach. The pressure head 559 is installed and removed via a threaded connection between it and the ring block 557. This allows for quick installation and removal of the pressure head 559 when it is worn, damaged, or needs to be replaced with a different size, reducing downtime and improving production efficiency. The pressure head 559 penetrates the cylinder 552 and extends into the protective cylinder 553. A slot 5510 is provided on the outer side of the pressure head 559, and multiple intermediate plates 5511 are fixedly connected to the inner wall of the slot 5510. The top of the ring block 557 is fixedly connected to a return spring 558. The hydraulic cylinder 4 passes through the cylinder. 552 drives the pressure head 559 to move downward, so that the pressure head 559 contacts the door panel. The return spring 558 is compressed, which causes the pressure head 559 to drive the ring block 557 to slide inside the slide groove 556. By setting the return spring 558 and the compression spring 213, the pressure head 559 can maintain a relatively stable pressure during the stamping process, which helps to improve the stamping accuracy and surface quality of the door panel and reduce stamping defects caused by uneven pressure. At the same time, the return spring 558 and the compression spring 213 play a buffering role, reducing damage to the pressure head 559, the door panel and other parts of the punch press, extending the service life, and preventing the door panel from deforming or being damaged due to excessive impact force. The end of the return spring 558 away from the ring block 557 is fixedly connected to the square plate 53.
[0018] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 9 As shown, the adjusting component 54 includes a pressure plate 541. A guide rod 549 is fixedly connected to the top of the pressure plate 541. Multiple guide rods 549 are evenly distributed at the top corners of the pressure plate 541. The guide rods 549 are slidably connected to the top plate 8. A through groove 542 is provided on the top of the pressure plate 541. When the hydraulic cylinder 4 operates, it drives the square plate 53 to move downwards. The square plate 53 drives the bottom pressure plate 541 to move downwards, causing the pressure plate 541 to contact the top of the door panel. At this time, the motor 545, powered by an external power source, operates, driving the rotating rod 546 to rotate. When the rotating rod 546 rotates, it drives the connecting rods 547 at both ends and the clamping blocks 544 to move along the inner wall of the through groove 542 towards the rotating rod 546, thus limiting the conveying direction of the door panel by the clamping blocks 544 on both sides. The door panel is positioned in the center of the designated location through the cooperation with the rotating plate 19, ensuring that the hole position matches the design requirements and avoiding deviations that could cause the door panel size to be non-compliant with specifications, thereby improving the product qualification rate. A round rod 543 is fixedly connected inside the through groove 542, and a support plate 548 is fixedly connected to the outside of the protective cylinder 553. A motor 545 is fixedly connected to the bottom of the support plate 548, and a rotating rod 546 is fixedly connected to the output end of the motor 545. The rotating rod 546 is rotatably connected to the top of the pressure plate 541. The through groove 542 is symmetrically arranged with the rotating rod 546 as the center. A connecting rod 547 is rotatably connected to the end of the rotating rod 546. A clamping block 544 is rotatably connected to the end of the connecting rod 547 away from the rotating rod 546. The clamping block 544 is located on the inner wall of the through groove 542, and the round rod 543 passes through the clamping block 544.
[0019] In use, the door panel is placed on the roller 15, and the motor 13 is powered by an external power source. The motor 13 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the roller 15 to rotate, so that the roller 15 moves the door panel. At this time, the door panel contacts and is squeezed by the rotating plates 19 on both sides. Under the elastic force of the arc plate 113, the rotating plate 19 drives the cylinder 111 to slide on the inner wall of the annular groove 18, so that the roller 110 on the outer side of the rotating plate 19 is in close contact with the door panel, so that the door panel is located in the middle of the roller 15.
[0020] Roller 15 moves the top door panel to the position to be processed. Then, electric push rod 23 works to push fixed plate 24 to move along the direction of fixed rod 22, so that fixed plate 24 drives the top fixed frame 25 through the gap between rollers 15 and extends to the top of roller 15, so that the fixed block 29 at the top of fixed frame 25 can lift the door panel from the surface of roller 15.
[0021] The hydraulic cylinder 4 drives the square plate 53 to move downwards, and the square plate 53 drives the bottom pressure plate 541 to move downwards, so that the pressure plate 541 contacts the top of the door panel. At this time, the motor 545 is powered by an external power source. The motor 545 drives the rotating rod 546 to rotate. When the rotating rod 546 rotates, it drives the connecting rods 547 at both ends and the clamping blocks 544 to move in the direction of the rotating rod 546 on the inner wall of the through groove 542. This causes the clamping blocks 544 on both sides to limit the door panel in the conveying direction. Through the cooperation with the rotating plate 19, the door panel is positioned in the middle of the designated position.
[0022] The square plate 53 drives the bottom cylinder 552 and protective cylinder 553 to move downward, so that the bottom of the protective cylinder 553 contacts the door panel. As the hydraulic cylinder 4 drives the square plate 53 to continue to move downward, the protective cylinder 553 moves towards the connecting block 551 inside the sliding groove 554, so that the pressure head 559 on the cylinder 552 presses the door panel.
