Description

Technical Field

[0001] This utility model relates to the technical field of elevator door panel processing equipment, specifically an automated bending and welding machine for elevator door panels. Background Technology

[0002] Elevator door panels are key components in elevator door structures, primarily used for the door facade, serving multiple functions including shielding, protection, and aesthetic enhancement. Elevator door panels are typically made of metal materials (such as steel plates or stainless steel), possessing good strength and durability. During manufacturing, elevator door panels undergo a series of precision processing steps, including bending and welding assembly. Bending transforms flat metal sheets into structural components with specific angles and shapes to meet the design requirements of the elevator door. Welding securely connects the various components, ensuring the stability and safety of the overall structure. In recent years, with the development of manufacturing technology, integrated bending and welding machines have been increasingly applied to elevator door panel production. This equipment can simultaneously complete both bending and welding processes within a single work unit, significantly improving production efficiency and processing accuracy. This integrated processing method not only simplifies the process flow but also reduces mold change and equipment switching time, minimizes manual intervention, and improves product consistency and quality stability.

[0003] However, current bending and welding integrated machines typically use multiple conveyor lines to transport various components. This not only requires multiple machines, resulting in high mechanical energy consumption, but also occupies a large space, affecting production efficiency and the flexibility of equipment layout.

[0004] Therefore, this utility model provides an automated bending and welding machine for elevator door panels to solve the above problems. Utility Model Content

[0016] This utility model provides an automated bending and welding machine for elevator door panels, such as... Figures 1-5 As shown, an automated bending and welding machine for elevator door panels includes a horizontal plate 1, an adjustment component fixedly installed on the upper surface of the horizontal plate 1, vertical plates 2 fixedly connected to both sides of the horizontal plate 1, and a conveying component fixedly installed on one side of the vertical plate 2. The adjustment assembly includes a first motor 3, the lower surface of which is fixedly mounted on the upper surface of the horizontal plate 1. A worm gear 4 is fixedly connected to the output end of the first motor 3. Worm wheels 5 mesh on both sides of the outer surface of the worm gear 4. An extension rod 6 is fixedly connected inside the worm wheels 5. Telescopic rods 7 are fixedly connected to both ends of the extension rod 6. A connecting block 8 is rotatably connected to the bottom end of the telescopic rod 7. A mounting bracket 9 is fixedly connected inside the connecting block 8. A rotating rod 10 is fixedly connected to the inner wall of the mounting bracket 9. A first roller 11 is rotatably connected to the outer surface of the rotating rod 10. Starting the first motor 3 drives the worm wheels 5 to rotate via the worm gear 4, and then the extension rod 11 rotates through the worm wheels 5. The extension rod 6 can drive the telescopic rod 7 to rotate, thereby driving the push mounting frame 9 to move up and down via the connecting block 8. At this time, the extension and retraction of the telescopic rod 7 can adapt to the distance changes generated during its movement, so that the telescopic rod 7 can effectively push the mounting frame 9, thereby adjusting the distance between the first roller 11 and the second roller 13. Meanwhile, the first roller 11 is set to roll under the connection of the rotating rod 10, which can realize the adaptation and conveying of elevator door panels of different thicknesses, improving the versatility and flexibility of the equipment. Moreover, the door panel can be flattened by the rolling action, effectively improving its surface flatness, thereby improving the overall quality of the product.

[0017] The conveying assembly includes a second motor 12, one side of which is fixedly installed on one side of the vertical plate 2. The output end of the second motor 12 is fixedly connected to a second roller 13, and one end of the second roller 13 is fixedly connected to a belt drive component 14. Starting the second motor 12 can drive the second roller 13 to rotate, and under the drive of the belt drive component 14, multiple second rollers 13 can rotate synchronously. The second rollers 13 can stably convey the elevator door panel to be welded. Thus, through the coordinated design of the first roller 11 and the second roller 13, the number of equipment is reduced while meeting functional requirements, mechanical energy consumption is reduced, space is saved, and the layout flexibility and operating efficiency of the production line are further improved.

[0018] There are several second rollers 13, and one end of each second roller 13 is connected to rotate in sequence via a belt drive 14. Multiple second rollers 13 rotate synchronously, which can realize the stable conveying of materials.

[0019] A top plate 15 is fixedly connected to one end of the upper surface of the vertical plate 2. A hydraulic rod 16 is fixedly installed on the upper surface of the top plate 15. A lower pressure block 17 is fixedly connected to the bottom end of the hydraulic rod 16. Activating the hydraulic rod 16 can drive the lower pressure block 17 to move up and down to bend the elevator door panel.

[0020] A guide rail 18 is fixedly connected to one side of the lower surface of the top plate 15. A sliding block 19 is slidably connected to the outer surface of the guide rail 18. An electric push rod 20 is fixedly connected to the lower surface of the sliding block 19. A welding head 21 is fixedly connected to the bottom end of the electric push rod 20. Activating the electric push rod 20 can control the lowering distance of the welding head 21, and then the sliding block 19 can drive the welding head 21 to slide on the outer surface of the guide rail 18. This allows for multiple welding operations on the elevator door panel and the part to be welded.

[0021] A base plate 22 is fixedly connected to the middle of the outer surface of the mounting frame 9. A bottom mold 23 adapted to the lower pressure block 17 is fixedly connected to the upper surface of the base plate 22. Force blocks 24 are fixedly connected to both sides of the lower surface of the base plate 22. The bottom mold 23 is adapted to the lower pressure block 17 to realize the bending of the elevator door panel. The base plate 22 is connected to the mounting frame 9 so that the base plate 22 can move up and down with the mounting frame 9 to receive the elevator door panel smoothly. The force block 24 is triangular, and one side of it overlaps with the front surface of the upright plate 2, which can provide effective support for the bottom of the base plate 22 and ensure the firmness of the base plate 22 when the lower pressure block 17 is pressed down.

[0022] Working steps: First, starting the second motor 12 drives the second roller 13 to rotate. Driven by the belt drive 14, multiple second rollers 13 can rotate synchronously, stably conveying the elevator door panel to be welded. Next, starting the first motor 3 drives the worm gear 5 via the worm 4, which in turn drives the telescopic rod 7 to rotate. This, via the connecting block 8, causes the jacking mounting frame 9 to move up and down. The telescopic rod 7's extension and retraction adapt to the distance changes during its movement, allowing it to effectively push the mounting frame 9. This, in turn, adjusts the distance between the first roller 11 and the second roller 12. The distance between the rollers 13, and the first roller 11, connected by the rotating rod 10, is set to roll, which can realize the adaptation and conveying of elevator door panels of different thicknesses. Next, the elevator door panel is conveyed to the top of the bottom mold 23. The hydraulic rod 16 is activated to drive the lower pressure block 17 to move up and down to bend the elevator door panel. Finally, the part to be welded of the elevator door panel is conveyed to the top of the elevator door panel. After adjustment by the external robotic arm, the electric push rod 20 is activated to control the lowering distance of the welding head 21. Then, the sliding block 19 drives the welding head 21 to slide on the outer surface of the guide rail 18, which can perform multiple welding on the part to be welded of the elevator door panel and the elevator door panel.
