Description

Technical Field

[0001] This invention relates to the technical field of elevator door panel processing, and in particular to an elevator door panel processing equipment and method. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. There are also escalator-type elevators, where steps are mounted on a continuous running track. They are commonly known as automatic escalators or moving walkways. They are fixed lifting devices that serve designated floors. Elevator door panels need to be bent during processing.

[0003] Existing elevator door panel processing equipment, when connected to an external power source, first bends one end of the elevator door panel using a bending machine. Then, a fixing device secures the door panel, and a motor drives the entire fixing device to rotate, allowing the other end of the door panel to be placed inside the bending machine for further bending. Compared to traditional methods, this device eliminates the need for manual adjustment of the elevator door panel during bending. The fixing and moving devices allow for easy bending of both ends of the door panel, saving processing time, increasing efficiency, and reducing labor intensity. The device has a simple structure and low operating costs, making it suitable for various types of businesses.

[0004] However, in actual operation, the elevator door panel to be bent needs to be manually placed into the placement groove, and one end of the door panel is bent. When the other end of the elevator door panel needs to be bent, the hydraulic telescopic rod needs to be activated to drive the suction cup below the motor to move down and adhere to the elevator door panel. The hydraulic telescopic rod drives the door panel to move up, lifting the bent part of the door panel out of the groove. Then the motor is activated to rotate the door panel, turning its other end into the bending groove. The hydraulic telescopic rod continues to drive the elevator door panel down, and finally the bending machine is activated to bend the other end of the elevator door panel. This results in a complex equipment structure, high manufacturing cost, increased energy consumption during processing, and reduced work efficiency. Therefore, there are areas for improvement.

[0015] Secondly, this application provides a method for processing elevator door panels, which adopts the following technical solution:

[0016] A method for processing elevator door panels includes the following steps:

[0017] Step 1: Stack the elevator door panels to be bent into the storage box. Based on the actual thickness of the elevator door panels, use the first turntable to rotate the first screw. Rotate the first turntable at the discharge port to move the baffle. Adjust the position of the baffle according to the thickness of the elevator door panels.

[0018] Step 2: Start the motor to drive the belt to rotate. Using the sliding of the first insert rod in the first guide groove, the grabbing bar grabs the bottom door panel in the storage frame and moves it to the feeding chute, automatically feeding the door panel onto the two support plates.

[0019] Step 3: Start the hydraulic press to move the two bending plates down, and bend the elevator door panel on the support plate;

[0020] Step 4: Finally, the hydraulic press drives the bending plate to move up and reset. The third rod on the lifting plate slides in the third guide groove on the second driving plate to push open the two support plates, so that the bent elevator door panel automatically falls onto the receiving plate for unloading.

[0021] 1. This invention provides a bending table equipped with a U-shaped frame, a hydraulic press, a lifting plate, a vertical rod, a bending plate, a feeding chute, and a support plate. Two bending plates are provided. After the elevator door panel is placed on the support plate, the hydraulic press is started to move the bending plate downwards, which can simultaneously bend both ends of the elevator door panel. This improves work efficiency, reduces the manufacturing cost of the equipment, and reduces energy consumption.

[0022] 2. The present invention has a discharge port, a fixing strip, a second guide rod, a baffle, a first screw and a first turntable set in the storage frame at the left end of the bending table. The storage frame can be used to centrally stack elevator door panels to be bent, and the turntable drives the rotation of the first screw. The position of the baffle can be flexibly adjusted according to the actual thickness of the elevator door panel, so that the elevator door panels in the storage frame can be smoothly discharged from the discharge port.

[0023] 3. This invention features a bending table equipped with a motor, rotating rod, pulley, belt, fixing rod, sleeve, first insert rod, sleeve block, and gripping strip. The bending table has a first groove and a first guide groove. When the motor is started and the belt rotates, the first insert rod slides from the first groove into the first guide groove, moving the sleeve on the fixing rod. This, in turn, moves the gripping strip to clamp onto the bottom elevator door panel in the storage frame. Lowering the clamping point moves the strip to the feeding slot, achieving automatic feeding. This makes operation more labor-saving and convenient, and improves work efficiency. Furthermore, a first spring connects the sleeve block to the fixing sleeve on the sleeve. The movement of the sleeve block on the sleeve causes the deformation of the first spring, allowing the gripping strip to grip elevator door panels of different sizes, making it more flexible in use.

[0024] 4. This invention provides an extrusion plate, a crossbar, and a second spring in the feed trough. The extrusion plate is equipped with a straightening plate, a T-shaped plate, and a third spring. The lifting plate is equipped with a vertical plate, a rotating shaft, and an extrusion sleeve. This allows the lifting plate to move the bending plate downwards for bending while the extrusion wheel pushes the extrusion plate, causing the straightening plate to move towards the elevator door panel on the support plate. This straightens the elevator door panel and pushes it to the position to be bent, thereby improving the quality of the bending process.

[0025] 5. The present invention comprises a first driving plate, a second guide groove, a first connecting rod, a first sliding groove, a second connecting rod, a second sliding groove, a sliding plate, and a protective frame respectively arranged in the bending table and the bottom groove. A second insert rod is connected to the lifting plate and passes through the second guide groove. When the lifting plate moves down to bend, it can drive the two protective frames to move and fit onto the upper and lower sides of the elevator door panel. This not only protects other parts of the elevator door body and reduces deformation during bending, but also limits the elevator door panel to avoid the elevator door panel from moving during bending and reducing the processing quality.

[0026] 6. The present invention provides a receiving plate below the bottom groove, and a second driving plate, a third connecting rod, and a third guide groove on the bending table. The third insert rod on the lifting plate passes through the third guide groove, and one end of the third connecting rod is connected to the support plate. After the elevator door panel is bent, the lifting plate moves up and resets. By sliding the third insert rod in the third guide groove, the two support plates can be automatically pushed open to both sides, so that the processed elevator door panel can automatically fall onto the receiving plate, thus realizing the automatic unloading function.

[0027] 7. This invention features an L-shaped rod, a vertical frame, an insertion plate, a fourth guide groove, and a fourth insert rod in the bottom groove. The top of the fourth insert rod is connected to a support plate. By moving the support plate back and forth, the bottom of the fourth insert rod can move back and forth in the bottom groove. Combined with the weight of the receiving plate itself, the receiving plate can automatically move down a certain distance when receiving materials in sequence, thereby ensuring the falling height of the elevator door panel and avoiding the problem of damage to the elevator door panel when it falls due to excessive falling height.

[0043] The following is in conjunction with the appendix Figures 1-14 The present invention will be described in further detail below.

[0044] This invention discloses an elevator door panel processing equipment.

[0045] Reference Figure 1An elevator door panel processing device includes a bending table 1 and a hydraulic press 4. Support legs 2 are welded to both ends of the bending table 1. A feeding trough 10 is formed in the middle of the upper part of the bending table 1. A bottom groove 34 communicating with the feeding trough 10 is formed in the middle of the lower part of the bending table 1. Support plates 11 are provided on both the front and rear sides of the bottom groove 34. Bending grooves are formed on the upper part of both support plates 11. A storage structure is provided at the upper left end of the bending table 1. A receiving structure is provided below the bottom groove 34 on the bending table 1. A U-shaped frame 3 is bolted to the upper part of the middle of the bending table 1. A hydraulic press 4 is installed in the middle of the upper part of the U-shaped frame 3. Vertical grooves 7 are provided on both the front and rear sides of the frame 3. First guide rods 6 are connected between the upper and lower ends of the groove walls of the vertical grooves 7. Lifting plates 5 are movably sleeved on the two first guide rods 6. The bottom end of the output shaft of the hydraulic press 4 is connected to the middle of the upper part of the lifting plate 5. Vertical rods 8 are connected to the lower part of the lifting plate 5 near both ends. Bending plates 9 are installed at the bottom ends of the two vertical rods 8. After the elevator door panel to be processed is placed on the two support plates 11 in the bottom groove 34, the hydraulic press 4 is directly started to drive the two bending plates 9 to move down. The two ends of the elevator door panel are bent on the support plates 11 at the same time. The operation is more labor-saving and convenient, and the work efficiency is improved.

[0046] See Figures 1-3 The storage structure includes a storage frame 13 located at the left end of the bending table 1. A discharge port 12 is provided at the lower side of the storage frame 13. The storage frame 13 is connected to one of the support legs 2 via a connecting plate 19. A fixing strip 14 is connected at the lower right side of the storage frame 13. A baffle 16 is provided below the fixing strip 14. A second guide rod 15 is connected to both ends of the baffle 16. Both second guide rods 15 extend movably out of the fixing strip 14. A first screw 17 passes through the threaded groove at the middle position of the fixing strip 14. The bottom end of the first screw 17 is rotatably connected to the baffle 16. A first turntable 18 is fixedly fitted on the top end of the first screw 17. The storage frame 13 is used to stack elevator door panels to be processed. The position of the baffle 16 can be adjusted by rotating the first screw 17 on the fixing strip 14 using the first turntable 18 according to the actual thickness of the elevator door panel.

[0047] Two rotating rods 20 extend from both ends of the bending table 1. Pulleys 21 are fixedly fitted at both ends of the two rotating rods 20. A belt 22 is fitted between the two sets of pulleys 21. A mounting base 23 is installed on the right side of the front of the bending table 1. A motor 24 is mounted on the mounting base 23. The output shaft of the motor 24 is connected to one end of one of the rotating rods 20. Fixed rods 27 are connected to the sides of the two belts 22 that are close to each other. A sleeve 28 is movably fitted onto the fixed rod 27. A first insert rod 29 is vertically fixed through the sleeve 28 near the middle position. A first groove 25 is formed on the bending table 1. The bottom end of the first insert rod 29 is inserted into the first groove 25. A first guide groove 26 is formed on the top of the bending table 1 near the middle position. The two ends of the first guide groove 26 connect to the two ends of the first groove 25 (the shapes of the first groove 25 and the first guide groove 26 are as follows). Figure 1 , Figure 2 and Figure 7 As shown, a sleeve block 30 is movably fitted onto one end of the sleeve 28. A gripping strip 31 is connected to the sleeve block 30. A fixing sleeve 32 is fixedly fitted onto the sleeve 28 near the sleeve block 30. A first spring 33 connects the sleeve block 30 and the fixing sleeve 32. When the starting motor 24 drives the pulley 21 and belt 22 to rotate as a whole, the belt 22 drives the fixing rod 27 and the sleeve 28 to move. When the first insertion rod 29 slides from the first groove 25 into the first guide groove 26, the belt... The moving sleeve 28 moves on the fixed rod 27, thereby driving the two gripping bars 31 to move and clamp to the side of the lowest elevator door panel inside the storage frame 13. As the belt 22 continues to rotate, it drives the elevator door panel to the top of the feeding trough 10. When the first insert rod 29 slides back from the first guide groove 26 into the first groove 25, the gripping bars 31 release the elevator door panel above the feeding trough 10, and the elevator door panel falls onto the two support plates 11 to realize the automatic feeding function.

[0048] See Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 12 , Figure 13 and Figure 14An extrusion plate 35 is positioned above the side of the support plate 11 within the feed trough 10. The top of the extrusion plate 35 is arched. Crossbars 36 are connected to both ends of the side of the extrusion plate 35 away from the support plate 11. One end of each crossbar 36 is movably inserted into a hole in the wall of the feed trough 10. A second spring 37 is fitted onto the crossbar 36, with both ends of the second spring 37 connected to the extrusion plate 35 and the wall of the feed trough 10, respectively. A second groove 38 is formed below the extrusion plate 35, and a straightening plate 40 is positioned within the second groove 38. T-shaped rods 39 are connected to both ends of the straightening plate 40 away from the support plate 11. The T-shaped rods 39 movably pass through the extrusion plate 35, and a second spring 37 is fitted onto the T-shaped rod 39. Three springs 41 are connected at both ends to the extrusion plate 35 and one end of the T-shaped rod 39, respectively. A vertical plate 42 is connected below the lifting plate 5 and above the extrusion plate 35. A rotating shaft 43 passes through the opening at the bottom of the vertical plate 42. An extrusion sleeve 44 is fitted on the rotating shaft 43. After the elevator door panel falls onto the support plate 11, the hydraulic press 4 can be started to drive the lifting plate 5 and the bending plate 9 to move down as a whole. The lifting plate 5 drives the vertical plate 42 to move down. The extrusion sleeve 44 at the bottom of the vertical plate 42 extrudes the upper arched surface of the extrusion plate 35, pushing the extrusion plate 35 to drive the straightening plate 40 to move towards one side of the elevator door panel, thereby pushing the elevator door panel on the support plate 11 to the position to be bent, so as to improve the bending processing quality.

[0049] The bending table 1 has a first driving plate 72 on both sides of the U-shaped frame 3. The first driving plate 72 has a second guide groove 45 (the shape of the second guide groove 45 is as follows). Figure 1 (As shown), a second insert rod 46 moves through the second guide groove 45. One end of the second insert rod 46 is connected to the lifting plate 5. The bottom end of the first driving plate 72 is connected to a first connecting rod 49. The bottom end of the first connecting rod 49 is connected to a first slider 48. A first slide groove 47 is provided on the side of the bending table 1 for the first slider 48 to slide. The end faces of the first slider 48 and the first slide groove 47 are both "T" shaped. A second connecting rod 50 is connected to the lower part of the side of the first driving plate 72. One end of the second connecting rod 50 extending into the bottom groove 34 is connected to a sliding plate 52. A second slide groove 51 is provided on the lower wall of the bottom groove 34 for the sliding plate 52 to slide. One end of the 2 is connected to a protective frame 53. The side of the protective frame 53 is U-shaped. When the lifting plate 5 moves down, it drives the second insert rod 46 to move in the second guide groove 45, pulling the first driving plate 72 to move towards the side closer to the U-shaped frame 3. The protective frame 53 is moved by the second connecting rod 50 and fitted onto the elevator door panel. This protects the part of the elevator door panel away from the bending part during the bending process, reducing the problem of deformation in other parts of the elevator door panel during the bending process. It can also limit the position of the elevator door panel, reducing the problem of positional displacement of the elevator door panel during the bending process, thus reducing the problem of reduced processing quality.

[0050] A second slider 54 is provided at both ends of the upper part of the support plate 11. The second slider 54 is slidably disposed in a third sliding groove 55 opened in the groove wall of the bottom groove 34. The end faces of the third sliding groove 55 and the second slider 54 are both "T" shaped. A third connecting rod 56 is connected to the middle of the lower part of the support plate 11. The top end of the third connecting rod 56 is connected to a second driving plate 57. A third guide groove 59 is opened on the second driving plate 57 (the shape of the third guide groove 59 is as follows). Figure 5 As shown, a third insert rod 60 moves through the third guide groove 59. One end of the third insert rod 60 is connected to the lifting plate 5. Two through rods 58 are connected to the lower part of the second driving plate 57 near the side of the U-shaped frame 3. Both through rods 58 move through the U-shaped frame 3. After the elevator door panel is processed, when the lifting plate 5 moves up and resets to the highest position, the sliding of the third insert rod 60 in the third guide groove 59 can push the two support plates 11 to move away from each other, so that the processed elevator door panel can fall automatically for unloading.

[0051] See Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The receiving structure includes L-shaped rods 61 connected to the four corners of the bottom trough 34. Each L-shaped rod 61 has a vertical frame 62 connected to one end. An insertion plate 64 is movably inserted into each vertical frame 62. The bottom ends of the four insertion plates 64 are connected to the receiving plate 63. A fourth guide groove 65 is formed on the side of the insertion plates 64 that are close to each other (the shape of the fourth guide groove 65 is as follows). Figure 9 As shown), a fourth insert rod 66 is inserted into the fourth guide groove 65. The top end of the fourth insert rod 66 is connected to the support plate 11. While the support plate 11 moves back and forth to unload the material, it drives the bottom end of the fourth insert rod 66 to slide back and forth in the fourth guide groove 65. By utilizing the gravity of the receiving plate 63 and the insertion plate 64, the receiving plate 63 can move downward intermittently during unloading, thus avoiding the problem of the elevator door panel falling from a high height and being damaged.

[0052] A fourth sliding groove 71 is provided on the side of the insertion plate 64. A sliding strip 70 is slidably disposed in the fourth sliding groove 71. A second screw 69 is rotatably connected to the sliding strip 70. The second screw 69 passes through a threaded groove on the vertical frame 62. A second turntable 68 is sleeved on one end of the second screw 69 that extends out of the vertical frame 62. A reset groove 67 is provided on the insertion plate 64. The reset groove 67 connects the upper and lower ends of the fourth guide groove 65. When the top of the fourth insertion rod 66 moves to the top wall of the fourth guide groove 65, the second screw 69 can be rotated by the second turntable 68, which drives the insertion plate 64 and the receiving plate 63 to move together in the vertical frame 62, so that one end of the fourth insertion rod 66 slides into the reset groove 67. In this way, after the processed elevator door panel is removed from the receiving plate 63, the receiving plate 63 can be pushed upward to reset it, so that the receiving plate 63 can continue to collect the next set of elevator door panels.

[0053] This invention also discloses a method for processing elevator door panels, comprising the following steps:

[0054] Step 1: Stack the elevator door panels to be bent into the storage box 13. According to the actual thickness of the elevator door panels, use the first turntable 18 to rotate the first screw 17. Rotate the first turntable 18 at the discharge port 12 to drive the baffle 16 to move. Adjust the position of the baffle 16 according to the thickness of the elevator door panels.

[0055] Step 2: Start the motor 24 to drive the belt 22 to rotate. Using the sliding of the first insert rod 29 in the first guide groove 26, the grabbing bar 31 grabs the bottom door panel in the storage frame 13 and moves it to the feeding groove 10, automatically feeding the door panel onto the two support plates 11.

[0056] Step 3: Start the hydraulic press 4 to move the two bending plates 9 down and bend the elevator door panel on the support plate 11;

[0057] Step 4: Finally, the hydraulic press 4 drives the bending plate 9 to move up and reset. The third insert rod 60 on the lifting plate 5 slides in the third guide groove 59 on the second driving plate 57 to push open the two support plates 11, so that the bent elevator door panel automatically falls onto the receiving plate 63 for unloading.

[0058] The implementation principle of the elevator door panel processing equipment and method of this invention is as follows: First, the elevator door panels to be processed are stacked in the storage frame 13. The motor 24 is started to drive the pulley 21 and belt 22 on the rotating rod 20 to rotate as a whole. When one end of the first insert rod 29 slides from the first groove 25 to the first guide groove 26, it drives the sleeve 28 to move on the fixed rod 27, thereby driving the two gripping strips 31 to move and clamp to the side of the elevator door panel at the bottom of the storage frame 13. As the belt 22 continues to rotate, the elevator door panel is pulled out from the discharge port 12 and moved to the position directly above the feed groove 10. Then, the first insert rod 29 slides back from the first guide groove 26 to the first groove 25, so that the gripping strips 31 are released from the elevator door panel. The elevator door panel automatically falls onto the support plate 11 for unloading. Then, the hydraulic press 4 is started to drive the lifting plate 5 to move down. During the downward movement of the lifting plate 5, the bottom of the vertical plate 42 is driven to move down. The extrusion sleeve 44 at the end moves down to extrusion plate 35, and extrusion plate 35 drives the straightening plate 40 to move, pushing the elevator door panel on the support plate 11 to the position to be processed. At the same time, the lifting plate 5 drives the second insert rod 46 to slide in the second guide groove 45, pulling the two protective frames 53 to move and fit onto the elevator door panel for protection. Then, the lifting plate 5 drives the two bending plates 9 to move down, and simultaneously bends both ends of the elevator door panel in the bending grooves on the two support plates 11. Next, the hydraulic press 4 drives the lifting plate 5 to move up. When the lifting plate 5 moves up to the highest position, the extrusion plate 35 and the straightening plate 40 move in opposite directions to reset, and drive one end of the third insert rod 60 to slide in the third guide groove 59, thereby pushing open the two support plates 11, so that the processed elevator door panel falls onto the receiving plate 63, realizing the automatic unloading function. In this way, the processing of the elevator door panel can be completed, making the operation more convenient and labor-saving, and improving the processing efficiency.

[0059] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
