Description

Technical Field

[0001] The utility model relates to the field of stamping of steel plate edges before bending, in particular to a steel plate processing device for elevator production. Background Art

[0002] The main structure of an elevator is the elevator car and the elevator door. When producing the elevator door, the steel plate needs to be processed into a door-shaped structure. This is mainly done by stamping the four corners of the steel plate, bending the steel plate to form an edge, and then welding a reinforcing keel on the inside of the edge. Finally, a steel plate is welded to seal the exposed side of the keel.

[0003] In the existing technology, when stamping the four corners of a steel plate, an operator is required to place the steel plate to be stamped in the stamping position, and then take the steel plate out after the stamping is completed. During the above process, manual operation is required. If an accidental touch occurs, the stamping mechanism can easily cause damage to the human hand, and there is room for further improvement in safety. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 8 In an embodiment of the utility model, a steel plate processing device for elevator production includes a base plate 1, a stamping mechanism is installed on the top of the base plate 1, and two rotating mechanisms are installed at one end of the base plate 1. The output end of the rotating mechanism at the top is connected to a pushing mechanism slidingly connected to the base plate 1, and the pushing mechanism is used to assist in loading or unloading the steel plate. The output end of the rotating mechanism at the bottom is connected to a sliding mechanism that drives the pushing mechanism to move axially. The interior of the base plate 1 is slidably connected to a limiting mechanism distributed in a herringbone shape, and the limiting mechanism is used to assist in placing the steel plate in the correct position; four waste holes 19 are vertically arranged inside the base plate 1, and the four waste holes 19 are used to guide out the punched-down steel plate.

[0026] In this embodiment: first, the steel plates are cut into the same size, and then the cut steel plates are placed on the top of the base plate 1, and one end of the steel plate is located between two limit blocks 17 set along the length direction of the base plate 1. Then, the rotating mechanism at the bottom is started first, and the rotating mechanism at the bottom drives the sliding mechanism to move, and the sliding mechanism drives the pushing mechanism to move until the push block 22 away from the driving mechanism passes the other end of the steel plate. At this time, the rotating mechanism at the top is started to run, and the rotating mechanism at the top drives the pushing block 22 to rotate 180 degrees, rotating from the bottom to the top, and then the rotating mechanism at the bottom is reversed. At this time, the sliding mechanism pushes the steel plate to the stamping processing position through the pushing mechanism;

[0027] Then the punching mechanism is started, which presses down to punch out the four corners of the steel plate, making it easier to bend the four sides of the steel plate to form the hemming of the elevator door. After the hemming is formed, the reinforcing keel can be welded inside the hemming.

[0028] After the stamping is completed, the stamping mechanism is reset, and the rotating mechanism at the top is driven again. The rotating mechanism drives the two push blocks 22 to rotate 180 degrees. At this time, the push block 22 previously used to push the steel plate to achieve loading rotates from the top to the bottom, while the other push block 22 rotates from the bottom to the top. Then the rotating mechanism at the bottom is started again, and the rotating mechanism at the bottom drives the sliding mechanism to move. The sliding mechanism pushes the pushing mechanism, and the pushing mechanism pushes the stamped steel plate outward;

[0029] In the above process, there is no need for manual loading and unloading of materials, which avoids personal injuries caused by the downward pressure of the stamping mechanism and is safer.

[0030] Please refer to Figure 1 and Figure 2The stamping mechanism includes a guide column 2 fixedly connected to the top of the fixed ear on the outside of the base plate 1, a top plate 3 is fixedly installed on the top of the guide column 2, a hydraulic cylinder 6 is installed on the top of the top plate 3, and the output end of the hydraulic cylinder 6 passes through the bottom of the top plate 3 and is connected to the sliding plate 4. The sliding ear of the sliding plate 4 is slidably connected to the outer wall of the guide column 2 through a linear bearing, and the inner wall of the sliding plate 4 is slidably connected to the sliding column 7 up and down. A protrusion is formed on the top of the sliding column 7, and a return spring 9 is fixedly connected between the bottom end of the protrusion and the top of the sliding plate 4. The return spring 9 is socketed with the sliding column 7, and a pressure plate 8 is welded to the bottom end of the sliding column 7. The bottom end of the sliding plate 4 is provided with a accommodating groove for accommodating the pressure plate 8. The bottom end of the sliding plate 4 is provided with four stamping blades 16 aligned with the waste hole 19. The inside of the guide column 2 is provided with a through hole 5 for the protrusion of the sliding column 7 to pass through.

[0031] In this embodiment: after the steel plate moves to the processing position, the hydraulic cylinder 6 is started, and the hydraulic cylinder 6 pushes the sliding plate 4 to slide downward along the outer wall of the guide column 2 until the pressure plate 8 presses the steel plate. At this time, the hydraulic cylinder 6 continues to run downward. At this time, the pressure plate 8 has no space to move downward, and the sliding plate 4 continues to move downward. The reset spring 9 is stretched, and the downward moving sliding plate 4 drives the stamping blade 16 to punch and cut the four corners of the steel plate, and the cut waste is discharged through the waste hole 19.

[0032] Please refer to Figure 1 and Figure 2 The rotating mechanism includes a forward and reverse motor 13 and two synchronous wheels 14. One synchronous wheel 14 is coaxially connected to the output end of the forward and reverse motor 13. The two synchronous wheels 14 are connected through a synchronous belt 15. The pushing mechanism includes a rotating rod 10 connected to the two synchronous wheels 14 above. The outer wall of the rotating rod 10 is slidably connected to two sliding rings 21. The outer wall of the sliding ring 21 is integrally formed with a push block 22. One push block 22 protrudes upward and the other push block 22 protrudes downward.

[0033] In this embodiment: the running forward and reverse motor 13 drives the synchronous wheel 14 connected to it to rotate, and the synchronous wheel 14 drives another synchronous wheel 14 to rotate synchronously through the synchronous belt 15. The rotating mechanism located above drives the pushing mechanism to rotate in the direction of one hundred and eighty degrees, and the rotating mechanism located below drives the sliding mechanism to move. The axially moving sliding mechanism can push the pushing mechanism to load or unload materials.

[0034] Please refer to Figure 3, the sliding mechanism includes a screw rod 11 connected to two synchronous pulleys 14 below. Two moving plates 12 are threadedly connected to the outer walls of the two screw rods 11. The vertical rod portions of the moving plates 12 are axially slidably connected to the bottom plate 1. A pushing ring 23 rotatably connected to the sliding ring 21 is installed at the top of the vertical rod portions of the moving plates 12, and the pushing ring 23 does not contact the rotating rod 10.

[0035] In this embodiment: when the rotating mechanism located below is operating, it drives the two screw rods 11 to rotate. At this time, the moving plates 12 move axially under the action of their internal threads. The moving plates 12 then drive the sliding ring 21 to move, and the sliding ring 21 drives the pushing ring 23 to move.

[0036] Please refer to the figure particularly. The limiting mechanism includes three sliding cavities 24 opened inside the bottom plate 1. The inner walls of the sliding cavities 24 are slidably connected with limiting blocks 17 penetrating above the bottom plate 1. A connecting spring 25 is fixedly installed between the bottom ends of the limiting blocks 17 and the bottom ends of the inner walls of the sliding cavities 24. The three sliding cavities 24 are distributed in a "pin" shape.

[0037] In this embodiment: the setting of the three limiting blocks 17 can enable the steel plate to move to the processing position. And when the stamping mechanism performs stamping, the limiting blocks 17 are forced to move downward along the inner walls of the sliding cavities 24 and can compress the connecting spring 25. After the stamping mechanism is reset, at this time, the connecting spring 25 resets to drive the limiting blocks 17 to reset upward.

[0038] Please refer to particularly Figure 3 , a circular groove 二十 is opened at the top end of the bottom plate 1, and the diameter of the circular groove 二十 is larger than the rotation diameter of the pushing block 22. A chute 18 recessed upward is opened at the bottom end of the bottom plate 1. The chute 18 is used for the sliding of the moving plate 12, and the inner cavity of the chute 18 is connected to the inner cavity of the circular groove 二十.

[0039] In this embodiment: the opening of the circular groove 二十 facilitates the rotation of the pushing block 22, and the opening of the chute 18 facilitates the sliding of the moving plate 12.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
