Description

Technical Field

[0001] This utility model relates to the field of elevator door panel processing technology, and in particular to a bending processing equipment for elevator door panels. Background Technology

[0002] The production of elevator door panels is becoming increasingly automated. In the early stages of elevator door panel production, it is necessary to bend the perimeter of the elevator door panel. However, the current operation does not have a device to fix the elevator door panel during the bending process. Moreover, when bending the next side of the elevator door panel after one side has been bent, the elevator door panel needs to be manually adjusted. This operation is not only unstable, but also not safe or efficient.

[0003] Chinese patent document CN209886521 U discloses an elevator door panel bending mechanism. A first cylinder is fixedly installed on the left end of the lower surface of a crossbeam, and a bending die is fixedly welded to the telescopic end below the first cylinder. A second cylinder is fixedly installed in the middle of the lower surface of the crossbeam, and a pressure block is fixedly welded to the telescopic end below the second cylinder. A bearing is installed in a through hole at the center of a support platform, and a motor is installed at the center of the lower surface of the support platform. The motor's shaft passes through the bearing and is welded to an operating table. This invention allows for convenient and quick switching of elevator door panels during bending, saving significant time and labor. Furthermore, it allows for pressing the elevator door panel during bending, preventing it from suddenly lifting and injuring workers.

[0004] The existing technology has the following problems:

[0005] When bending the elevator door panels on different sides using the aforementioned mechanism, the elevator door panels are not restricted on the operating table and are easily moved, which increases the processing error of the mechanism. Secondly, during the processing of the aforementioned mechanism, the elevator door panels need to be placed on the operating table manually, which has low precision, and the manual operation directly under the pressure block is somewhat dangerous, thus its practicality is limited.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-6 As shown, a bending processing equipment for elevator door panels includes a base plate 1. An operating table 11 is fixedly installed on the upper left side of the base plate 1. A moving limit component 2 is movably connected to the upper end of the operating table 11. A positioning component 3 is movably connected to the bottom of the moving limit component 2. A bending mechanism 4 is fixedly installed on the right side of the upper rear part of the base plate 1.

[0029] The movable limiting assembly 2 includes a screw 21, the left and right ends of which are rotatably connected to the upper rear part of the operating table 11. A handwheel is fixedly installed on the left end of the screw 21. A slider 22 is threadedly connected to the outer wall of the screw 21. Guide rails 23 are fixedly installed on both the front and rear parts of the upper end of the operating table 11. A moving plate 24 is slidably connected to the inner wall of the two guide rails 23. The front side of the slider 22 is detachably connected to the rear left side of the moving plate 24. A baffle 25 is fixedly installed on the upper right side of the base plate 1.

[0030] The positioning component 3 includes a processing table 31. A rotating mechanism is fixedly installed at the upper middle part of the operating table 11. The top of the rotating mechanism is fixedly connected to the lower middle part of the processing table 31. An adjustable reverse double threaded rod 32 is rotatably connected to the left and right positions of the lower front part of the processing table 31. The outer walls of the reverse double threaded rod 32 are threaded with threaded sleeves 33 on both the left and right sides. A positioning mechanism is fixedly installed at the lower end of the two threaded sleeves 33. The upper front and rear parts of the processing table 31 are slidably connected with symmetrically arranged L-shaped frames 34. Fixing blocks 35 are fixedly installed at the front and rear positions of the left and right sides of the upper left and right parts of the processing table 31. Moving rods 36 are slidably connected to the inner walls of the four fixing blocks 35. The opposite ends of the four adjacent moving rods 36 are fixedly connected to the left and right sides of the two L-shaped frames 34 on the side away from each other.

[0031] The workpiece can be moved and conveyed to a designated position by the movable limiting component 2, facilitating processing by the bending mechanism 4 with high precision. Furthermore, the worker does not need to approach the bending mechanism 4, ensuring strong safety. The positioning component 3 allows processing on both sides of the workpiece. After bending one side, the rotating mechanism can rotate the processing table 31 180°, allowing the elevator door panel to be bent on the other side, saving processing time. Simultaneously, the limiting frame 312 at the bottom of the processing table 31, which can move left and right, and the pressing plate 316 at its top, which can move up and down, not only ensure the stability of the elevator door panel bending but also keep the workpiece always at the rectangular center of the processing table 31, improving the bending precision and reducing errors.

[0032] like Figure 4 As shown, the rotating mechanism includes a mounting frame 37. A rotating column 38 is rotatably connected to the middle position of the bottom of the inner wall of the mounting frame 37. The upper end of the rotating column 38 passes through the top of the mounting frame 37 and is fixedly connected to the middle of the lower end of the processing table 31. A motor 39 is fixedly installed at the front position of the top of the inner wall of the mounting frame 37. A gear 310 is fixedly sleeved at the output end of the motor 39. A gear 311 is fixedly sleeved at the bottom of the outer wall of the rotating column 38. The outer surface of the gear 310 meshes with the outer surface of the gear 311.

[0033] The output end of motor 39 can drive gear 310 to rotate. Gear 311 can drive the rotating column 38 to rotate 180° by meshing with gear 310, so that the processing table 31 can drive the elevator door panel to quickly change sides and bend, saving processing time.

[0034] like Figure 5 As shown, the positioning mechanism includes two limiting frames 312. The lower end of the processing table 31 is provided with sliding grooves 313 at both the front and rear. The upper ends of the two limiting frames 312 are slidably connected to the left and right sides of the inner walls of the two sliding grooves 313 at their respective front and rear positions.

[0035] The inner walls of the two limiting frames 312 can limit the left and right sides of the elevator door panel, and the slide 313 guides the movement of the limiting frames 312.

[0036] like Figure 5 As shown, the lower ends of the two threaded sleeves 33 are fixedly connected to the lower front parts of the two limiting frames 312 on the side that are close to each other.

[0037] The threaded sleeve 33 can move the two limit frames 312 closer to each other or further apart.

[0038] like Figure 5 As shown, elastic elements 314 are movably sleeved on the outer walls of the four adjacent movable rods 36 on the sides that are far apart from each other.

[0039] The elastic element 314 is a spring, which mainly provides the restoring force and elastic compressive force for the moving rod 36.

[0040] like Figure 6 As shown, the inner walls of the upper middle part of the two L-shaped frames 34 are threaded with adjusting screws 315. The left and right positions of the middle part of the opposite side of the two L-shaped frames 34 are provided with guide grooves. The inner walls of the four adjacent guide grooves are slidably connected with extrusion plates 316. The lower ends of the two adjusting screws 315 are rotatably connected to the upper middle part of the two extrusion plates 316.

[0041] Rotating the two adjusting screws 315 can move the corresponding extrusion plate 316, which can fix the front and rear positions of the top of the elevator door panel on the processing table 31, increase the fixing points, and ensure the stability of the elevator door panel processing.

[0042] like Figure 1 and Figure 2 As shown, the bending mechanism 4 includes a mounting frame 41, a linear moving mechanism 42 is fixedly mounted on the top of the mounting frame 41, and a bending plate 43 is fixedly mounted on the bottom of the linear moving mechanism 42. The bending plate 43 is located to the left of the baffle 25.

[0043] The linear moving mechanism 42 is electrically driven and is an existing mechanism, mainly composed of a hydraulic cylinder and a guide rod. The linear moving mechanism 42 can drive the bending plate 43 to contact the top of the elevator door panel, and the side of the elevator door panel will be bent into a specified shape under the action of the bending plate 43 and the side of the processing table 31.

[0044] The working principle of this utility model is as follows: In use, move the two L-shaped frames 34 so that they compress the corresponding number of elastic elements 314 and move away from each other. Place the elevator door panel on the upper end of the processing table 31. After releasing the two L-shaped frames 34, the four elastic elements 314 release their elastic potential energy at the same time, causing the two L-shaped frames 34 to reset. The L-shaped frames 34 can limit the front and rear sides of the elevator door panel through the elastic force of the elastic elements 314. Then rotate the reverse double threaded rod 32. The two threaded sleeves 33 are connected to the reverse double threaded rod 32 and move closer to each other, so that the two limiting frames 312 move closer to each other and lock and fix the left and right sides of the elevator door panel. During this process, the elevator door panel will be positioned at the rectangular center of the processing table 31, which can reduce processing errors and ensure its accuracy when processing the other side.

[0045] The worker rotates the handwheel, which drives the screw 21 to rotate. The slider 22 moves to the right through its threaded connection with the screw 21. The slider 22 drives the moving plate 24 to move between the two guide rails 23. The worker stops rotating the handwheel when the right side of the two limit frames 312 contacts the baffle 25. At this time, the right side of the elevator door panel is directly below the bending plate 43. The linear moving mechanism 42 is electrically driven, which drives the bending plate 43 to move downward. The side of the elevator door panel is bent into the specified shape under the action of the bending plate 43 and the side of the processing table 31. Then the worker rotates the handwheel in the opposite direction to return the moving plate 24 to its original position. The motor 39 starts, and its output can drive the gear 1 310 to rotate. The gear 2 311, through meshing with the gear 1 310, can drive the rotating column 38 to rotate 180°. Then, the side of the elevator door panel that is now on the other side is moved to the bottom of the bending mechanism 4 for bending again, which saves equipment processing time.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
