Description

Technical Field

[0001] This utility model relates to the field of bending processing equipment technology, and more specifically, to an elevator door panel bending processing equipment that is easy to control. Background Technology

[0002] In the manufacturing process of elevator door panels, bending is the core process that determines the structural precision and appearance quality of the door panel. It needs to meet the requirements of accurate angle, no surface damage, and adaptability to multiple door panel sizes. However, the traditional bending process of elevator door panels is mostly a single bending in one direction, which is prone to problems such as excessive angle deviation or door panel cracking. In addition, sliding friction contact can easily damage the surface of the door panel.

[0003] Existing publication number CN223097700U discloses an elevator door panel bending processing device, relating to the field of elevator door panel processing technology. It includes a worktable, with an extension platform fixedly installed on the side of the worktable. Several conveying rollers are rotatably connected within the extension platform. A motor is fixedly installed at one end of the extension platform near the worktable. A bidirectional screw is fixedly installed on the output shaft of the motor. One end of the bidirectional screw is fixedly connected to the motor, and the other end is rotatably connected to the extension platform. A pair of threaded sleeves are symmetrically arranged on the bidirectional screw, and a connecting rod is fixedly installed on each threaded sleeve. A through groove matching the connecting rod is opened on the extension platform, and the connecting rod passes through the extension platform and is fixedly connected to a limit block. This invention solves the problem in the prior art where, after pushing the elevator door panel against the limit block, a pair of locking bolts need to be manually tightened to lock the position of the push plate, affecting the working efficiency of the device. The inventors discovered the following problems in the prior art during the development of this utility model:

[0004] Traditional elevator door panel bending processing equipment often uses a single-direction, single-bending method, which frequently results in excessive angle deviations or cracking of the door panel due to excessive bending in one go. Furthermore, the bending process often involves sliding friction contact, which can easily leave scratches and indentations on the door panel surface, damaging the appearance quality. The limiting mechanism is poorly designed, often relying on simple baffles or manual assistance for positioning. During processing, the door panel is prone to shifting or moving, resulting in inconsistent bending positions for door panels in the same batch.

[0005] Therefore, an elevator door panel bending processing device that is easy to control is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an elevator door panel bending processing device that is easy to control, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator door panel bending processing device that is easy to control, comprising a worktable, a limiting mechanism, and a bending mechanism. The limiting mechanism is installed above the worktable, and the bending mechanism is provided on the side of the limiting mechanism. The limiting mechanism includes a pushing component and a sliding groove component, and the sliding groove component is installed on the side of the pushing component. The bending mechanism includes an extrusion component, a first driving component, and a second driving component, and the first driving component is installed above the extrusion component, and the second driving component is provided on the side of the extrusion component.

[0008] Preferably, the pushing assembly includes a first cylinder, a pushing rod, and a sliding block, wherein the pushing rod is mounted on the side of the first cylinder, and the sliding block is mounted on the side of the pushing rod away from the first cylinder.

[0009] Preferably, the slide rail assembly includes a first limiting slide rail plate, a second limiting slide rail plate, and a top plate, wherein the top plate is installed on the side of the first limiting slide rail plate, and the second limiting slide rail plate is installed on the side of the top plate away from the first limiting slide rail plate.

[0010] Preferably, the extrusion assembly includes an extrusion roller, a bearing housing, and a mounting plate, wherein the bearing housing is mounted on the side of the extrusion roller, and the mounting plate is mounted on the top of the bearing housing.

[0011] Preferably, the first drive assembly includes a hydraulic cylinder, a first push-pull rod, and a first fixing block, and the first push-pull rod is installed below the hydraulic cylinder, and the first fixing block is installed below the first push-pull rod.

[0012] Preferably, the second drive assembly includes a second cylinder, a second push rod, and a second fixing block, and a second push rod is mounted on the side of the second cylinder, and a second fixing block is mounted on the side of the second push rod away from the second cylinder.

[0014] Preferably, the workbench surface is stepped, and the workbench and the limiting mechanism are connected by welding, and the workbench and the bending mechanism are connected by welding.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this easy-to-control elevator door panel bending processing device achieves bending processing on both sides of the elevator door panel through the coordinated design of the first drive assembly, the second drive assembly, and two sets of extrusion assemblies. First, the first drive assembly uses a hydraulic cylinder as a power source and transmits high-pressure thrust to the first set of extrusion assemblies through the first push-pull rod and the first fixing block, so that the extrusion roller applies pressure from above the door panel to complete the first bending. At this time, the door panel is designed with a reserved angle greater than 90 degrees. Subsequently, the second drive assembly uses a second cylinder as a power source and drives the second set of extrusion assemblies to move from the side of the door panel through the second push-pull rod and the second fixing block. Together with the stepped table surface of the workbench, it forms lateral support and performs a second extrusion on the door panel, so that the bending angle is accurately close to 90 degrees.

[0017] 2. Compared with the prior art, this easy-to-control elevator door panel bending processing device effectively prevents the door panel from shifting during processing through the combined design of the push component and the slide rail component. The push component, as an active positioning structure, is powered by the first cylinder and drives the sliding block to contact the door panel through the push rod. It can smoothly push the door panel along the preset path and push the door panel under the bending mechanism so that the bending mechanism can bend the door panel. During this process, the slide rail component, as a passive guiding structure, forms a guide channel in the left and right directions through the first limit slide rail plate and the second limit slide rail plate, which restricts the lateral shift of the door panel. The top plate covers the two slide rail plates and constrains the vertical displacement of the door panel. The U-shaped limiting space formed by the three components makes the door panel move only along a linear path under the action of the push component. Even when the bending mechanism performs high-pressure bending, the top plate can still firmly restrict the vertical jump of the door panel. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 4 The illustrated elevator door panel bending processing device includes a worktable 1, a limiting mechanism 2, and a bending mechanism 3. The limiting mechanism 2 is installed above the worktable 1, and the bending mechanism 3 is provided on the side of the limiting mechanism 2. The limiting mechanism 2 includes a pushing component 4 and a sliding groove component 5. The sliding groove component 5 is installed on the side of the pushing component 4. The bending mechanism 3 includes an extrusion component 6, a first drive component 7, and a second drive component 8. The first drive component 7 is installed above the extrusion component 6, and the second drive component 8 is provided on the side of the extrusion component 6.

[0026] In this system, the workbench 1 serves as the basic support carrier of the entire device, providing a stable working platform for subsequent limiting and bending processes. Through the limiting mechanism 2 and the bending mechanism 3, the two form a coordinated process for positioning and processing. The limiting mechanism 2 is responsible for positioning the elevator door panel to prevent the door panel from shifting during processing. The bending mechanism 3 is responsible for performing the bending action. The limiting mechanism 2 can be further subdivided into a pushing component 4 and a sliding component 5. The pushing component 4 is responsible for active positioning, and the sliding component 5 is responsible for passive guidance. The bending mechanism 3 can be further subdivided into an extrusion component 6 and a first drive component 7 and a second drive component 8. The extrusion component 6 directly contacts the elevator door panel to bend it, while the first drive component 7 and the second drive component 8 provide power to the extrusion component 6, enabling it to apply pressure to the elevator surface in one direction.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the pushing assembly 4 includes a first cylinder 9, a pushing rod 10, and a sliding block 11. The pushing rod 10 is mounted on the side of the first cylinder 9, and the sliding block 11 is mounted on the side of the pushing rod 10 away from the first cylinder 9. The first cylinder 9 of the pushing assembly 4 serves as a power source, using the pressure of compressed air to convert into linear thrust. The power is transmitted to the sliding block 11 through the pushing rod 10. The sliding block 11 directly contacts the elevator door panel. Under the controllable drive of the cylinder, the door panel can be pushed along a preset path until the door panel reaches the limit position of the slide groove assembly 5. During the bending process of the door panel, the pushing assembly 4 can push the door panel to the bottom of the bending mechanism 3 to achieve the bending process of the door panel.

[0030] In a preferred embodiment, the slide rail assembly 5 includes a first limiting slide rail plate 12, a second limiting slide rail plate 13, and a top plate 14. The top plate 14 is installed on the side of the first limiting slide rail plate 12, and the second limiting slide rail plate 13 is installed on the side of the top plate 14 away from the first limiting slide rail plate 12. The slide rail assembly 5 forms a left-right guide channel through the first limiting slide rail plate 12 and the second limiting slide rail plate 13, which restricts the lateral displacement of the door panel. The top plate 14 covers the two slide rail plates, forming a vertical limiting channel, which restricts the vertical displacement of the door panel. The three together constitute a U-shaped limiting space, so that the elevator door panel can only move linearly along the slide rail channel under the action of the pushing assembly 4. Moreover, when the bending mechanism 3 bends the elevator door panel, the top plate 14 can prevent the door panel from shifting its position during the bending process.

[0031] In a preferred embodiment, the extrusion assembly 6 includes an extrusion roller 15, a bearing seat 16, and a mounting plate 17. The bearing seat 16 is mounted on the side of the extrusion roller 15, and the mounting plate 17 is mounted on the top of the bearing seat 16. The extrusion assembly 6 uses the extrusion roller 15 as a direct bending actuator, which contacts the elevator door panel through its cylindrical surface and applies bending pressure under the action of the first drive assembly 7. The bearing seat 16 provides rotational support for the extrusion roller 15, so that the extrusion roller 15 can roll synchronously with the door panel when pressure is applied, converting sliding friction into rolling friction and reducing damage to the door panel surface. The mounting plate 17 connects and fixes the extrusion assembly 6 and the first drive assembly 7.

[0032] In a preferred embodiment, the first drive assembly 7 includes a hydraulic cylinder 18, a first push-pull rod 19, and a first fixing block 20. The first push-pull rod 19 is installed below the hydraulic cylinder 18, and the first fixing block 20 is installed below the first push-pull rod 19. The first drive assembly 7 is based on the hydraulic high-pressure drive principle, using the hydraulic cylinder 18 as a power source, and transmitting hydraulic pressure to the first fixing block 20 through the first push-pull rod 19. The first fixing block 20 is rigidly connected to the mounting plate 17 of the extrusion assembly 6, so that the thrust of the hydraulic cylinder 18 is directly converted into the bending pressure of the extrusion roller 15, and the surface of the elevator door panel is extruded.

[0033] In a preferred embodiment, the second drive assembly 8 includes a second cylinder 21, a second push-pull rod 22, and a second fixing block 23. A second push rod 22 is mounted on the side of the second cylinder 21, and a second fixing block 23 is mounted on the side of the second push rod 22 away from the second cylinder 21. A set of extrusion assemblies 6 is also mounted on the side of the second drive assembly 8. The second drive assembly 8 uses the second cylinder 21 as a power source and transmits the thrust to the second fixing block 23 through the second push-pull rod 22. The second fixing block 23 is connected to the mounting plate 17 of the other set of extrusion assemblies 6 and can drive the extrusion assemblies 6 to move horizontally. When the first drive assembly 7 drives the extrusion assemblies 6 to bend the door panel from above, the angle after bending is significantly greater than 90 degrees. At this time, the second drive assembly 8 will drive the other set of extrusion assemblies 6 from the side of the door panel, in conjunction with the stepped surface of the workbench 1, to perform a secondary extrusion process on the door panel, so that the angle of the door panel approaches 90 degrees.

[0034] In a preferred embodiment, the bearing housing 16 and the extrusion roller 15 are connected by bearings, and two sets of bearing housings 16 are provided. The bearing housing 16 and the mounting plate 17 are connected by welding.

[0035] In a preferred embodiment, the table surface of the workbench 1 is stepped, the workbench 1 and the limiting mechanism 2 are connected by welding, and the workbench 1 and the bending mechanism 3 are connected by welding.

[0036] The working process of this utility model is as follows: First, when the operator uses the device to bend the elevator door panel, the elevator door panel to be processed is placed on the stepped surface of the workbench 1, ensuring that one end of the door panel is aligned with the limiting mechanism 2. Then, the pushing component 4 is activated, and the first cylinder 9 serves as the power source, using compressed air pressure to convert into linear thrust. The power is transmitted to the sliding block 11 through the pushing rod 10. The sliding block 11 directly contacts the elevator door panel, pushing the door panel to move along the guide channel of the slide groove component 5. At this time, the first limiting slide groove plate 12 and the second limiting slide groove plate 13 in the slide groove component 5 restrict the lateral displacement of the door panel, and the top plate 14 constrains the vertical displacement of the door panel. The U-shaped limiting space formed by the three ensures that the door panel moves linearly only along the preset path until the door panel reaches the designated bending position and extends below the bending mechanism 3.

[0037] Next, the first drive assembly 7 is activated, and the hydraulic cylinder 18 outputs high-pressure power, which is transmitted to the first fixed block 20 through the first push-pull rod 19. The first fixed block 20 is rigidly connected to the mounting plate 17 of the extrusion assembly 6, thereby driving the extrusion roller 15 to apply downward pressure. The extrusion roller 15 is connected to the bearing seat 16 through bearings. The two sets of bearing seats 16 ensure the stable rotation of the extrusion roller 15. The extrusion roller 15 contacts the door panel with its cylindrical surface, applying bending pressure to the door panel during rolling, completing the first bend. At this time, the bending angle of the door panel is greater than 90 degrees. Then, the second drive assembly 8 is activated, and the second drive assembly 9 is activated. The two cylinders 21 generate thrust, which is transmitted to the second fixed block 23 through the second push-pull rod 22. The second fixed block 23 is connected to the mounting plate 17 of another set of extrusion components 6, driving the set of extrusion components 6 to move horizontally. It performs secondary extrusion from the side of the door panel in conjunction with the stepped surface of the workbench 1, so that the bending angle of the door panel approaches 90 degrees. Throughout the process, the workbench 1 is firmly connected to the limiting mechanism 2 and the bending mechanism 3 through welding, ensuring that all components work together to finally complete the bending process of the elevator door panel. The above is the working principle of this easy-to-control elevator door panel bending processing device.
