Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to a stamping die for an elevator mounting bracket. Background Technology

[0002] In today's modern construction industry, elevators have become an indispensable tool for vertical transportation. With the continuous emergence of high-rise buildings and people's increasing demands for elevator safety, comfort, and operational efficiency, the elevator industry has experienced rapid development. As a crucial component of the elevator system, the elevator mounting bracket plays a vital role in supporting, fixing, and ensuring the smooth operation of the elevator; its quality and performance directly affect the safety and stability of the entire elevator system.

[0003] In the manufacturing process of elevator mounting brackets, stamping technology is widely used due to its high efficiency, high precision, and ability to be mass-produced. However, traditional elevator mounting bracket stamping dies have revealed a series of problems that urgently need to be solved in practical use.

[0004] Firstly, the methods for fixing the support plate during the stamping process are often inadequate and unreliable. Due to the lack of effective clamping and positioning mechanisms, the support plate is highly susceptible to displacement and wobbling under stamping pressure. This instability significantly reduces stamping accuracy, leading to deviations in the size and shape of the support, failing to meet stringent design requirements. The resulting defective products not only increase production costs but may also delay production schedules, affecting subsequent installation and use.

[0005] Secondly, the process of removing the formed bracket from the mold after stamping is also challenging. Traditional molds typically lack a specially designed automatic ejection mechanism, meaning that manual labor is required to pry or eject the bracket from the mold using tools. This manual operation is not only inefficient and time-consuming, but it also easily causes scratches, bumps, and other damage to the surface of the bracket during the operation, affecting its appearance quality and mechanical properties.

[0006] To address this, we propose a stamping die for elevator mounting brackets. This device can achieve stable adsorption and fixation of the bracket plate during the stamping process, ensuring stamping accuracy and quality. After stamping, it can automatically eject the formed bracket for easy handling and improve production efficiency. Utility Model Content

[0007] The purpose of this invention is to provide a stamping die for an elevator mounting bracket. This device can achieve stable adsorption and fixation of the bracket plate during the stamping process, ensuring stamping accuracy and quality. After stamping, it can automatically eject the formed bracket for easy handling and improve production efficiency.

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A stamping die for an elevator mounting bracket includes a bracket, a lower die assembly is disposed on the bracket, and an upper die body is disposed above the lower die assembly;

[0010] The lower mold assembly includes a lower mold body fixedly mounted on the bracket and a connecting plate mounted on the bracket. A rotating component is provided on the connecting plate, and a first semi-circular block is provided on the rotating component. The lower mold body has a forming groove and multiple sets of first through holes. A rubber piston is provided inside each set of first through holes. A first connecting rod is provided at the bottom of the rubber piston. A movable plate is installed at the bottom of the first connecting rod. A first elastic component connected to the bracket is provided at the bottom of the movable plate. A second semi-circular block located below the first semi-circular block is fixedly mounted on the movable plate. Multiple second through holes and multiple limiting holes are provided on the inner wall of the bottom of the forming groove. A second connecting rod is provided inside each second through hole. An ejector block connected to the second connecting rod is provided inside each limiting hole. A third semi-circular block located above the first semi-circular block is provided at the bottom of the second connecting rod. A second elastic component is provided on the third semi-circular block, and the top of the second elastic component is connected to the bottom of the lower mold body.

[0011] Furthermore, the rotating assembly includes a stepper motor disposed on the connecting plate, the output end of which is connected to the first semi-circular block.

[0012] Furthermore, the arc surface of the second semicircular block faces upward, and the arc surface of the third semicircular block faces downward.

[0013] Furthermore, the first elastic component includes a first hollow cylinder disposed on the bracket, a first spring disposed inside the first hollow cylinder, a first piston disc disposed on the top of the first spring, a first movable rod mounted on the first piston disc, and the top of the first movable rod extending through the first hollow cylinder and connecting to the movable plate.

[0014] Furthermore, the second elastic component includes a second hollow cylinder disposed at the bottom of the lower mold body, a second spring disposed inside the second hollow cylinder, a second piston disc disposed at the bottom of the second spring, a second movable rod mounted on the second piston disc, and the bottom of the second movable rod passing through the second hollow cylinder and connecting to the third semi-circular block.

[0015] Furthermore, the first semicircular block, the second semicircular block, and the third semicircular block are all provided with smooth surfaces.

[0016] The technical effects achieved by this utility model are as follows:

[0017] Firstly, as Figure 2 As shown, the support plate is placed on the lower die body, and then the upper die body moves downward for stamping. Before stamping, the rotating assembly is activated, which drives the first semi-circular block to rotate, causing the arc surface of the first semi-circular block to contact and press against the arc surface of the second semi-circular block. This causes the second semi-circular block to drive the movable plate downward and press against the first elastic component. At the same time, the movable plate drives the first connecting rod to move the rubber piston inside the first through hole, thereby generating suction to fix the support plate and prevent it from moving during stamping. After stamping, the upper die body returns to its original position. At this time, the plane of the first arc block contacts the arc surface of the third semi-circular block, and the second elastic component... The component returns to its original position, driving the second connecting rod to insert the ejector block into the limiting plate, facilitating bracket forming. Simultaneously, the rotating component rotates in the opposite direction. At this time, the arc-shaped plate of the first semicircular block contacts the arc-shaped surface of the third semicircular block, causing the third semicircular block to move the second connecting rod inside the second through hole. During this movement, the second elastic component is compressed, and the second connecting rod drives the ejector block to push out the formed bracket, making it easy to remove. When the ejector block is pushed out, the flat surface of the first semicircular block contacts the arc-shaped surface of the second semicircular block, and the first elastic component returns to its original position. This causes the movable plate to drive the first connecting rod, moving the rubber piston upward, thus starting the next operation. This device can achieve stable adsorption and fixation of the bracket plate during the stamping process, ensuring stamping accuracy and quality; after stamping, it can automatically eject the formed bracket for easy removal, improving production efficiency.

[0026] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-6 As shown, the technical solution adopted in this utility model is as follows: a stamping die for an elevator mounting bracket 1, including a bracket 1, a lower die assembly on the bracket 1, and an upper die body 2 above the lower die assembly;

[0028] The lower mold assembly includes a lower mold body 3 fixedly mounted on a bracket 1 and a connecting plate 4 mounted on the bracket 1. A rotating component is mounted on the connecting plate 4, and a first semi-circular block 5 is mounted on the rotating component. A forming groove 6 and multiple sets of first through holes 7 are formed on the lower mold body 3. A rubber piston 8 is installed inside each set of first through holes 7. A first connecting rod 9 is installed at the bottom of the rubber piston 8. A movable plate 10 is installed at the bottom of the first connecting rod 9. A first elastic component connected to the bracket 1 is installed at the bottom of the movable plate 10. A second semi-circular block 11 located below the first semi-circular block 5 is fixedly mounted on the movable plate 10. Multiple second through holes and multiple limiting holes are opened on the inner wall of the bottom of the forming groove 6. A second connecting rod 12 is installed inside each second through hole. An ejector block 13 connected to the second connecting rod 12 is installed inside each limiting hole. A third semi-circular block 14 located above the first semi-circular block 5 is installed at the bottom of the second connecting rod 12. A second elastic component is installed on the third semi-circular block 14. The top of the second elastic component is connected to the bottom of the lower mold body 3.

[0029] The rotating component includes a stepper motor 15 mounted on the connecting plate 4. The output end of the stepper motor 15 is connected to the first semi-circular block 5. The stepper motor 15 drives the first semi-circular block 5 to rotate, thereby performing the operation.

[0030] It should be noted that in the prior art, the manufacturing dimensions of the molds are very precise. Therefore, when the support plate 1 is placed on the lower mold body 3, the support plate 1 and the first through hole 7 are sealed. This arrangement allows the rubber piston 8 to generate suction force for adsorption and fixation when it moves. This is prior art and will not be elaborated on here.

[0031] Meanwhile, the arc surface of the second semicircular block 11 faces upward, and the arc surface of the third semicircular block 14 faces downward. This arrangement facilitates the operation of the first semicircular block 5.

[0032] The first elastic component includes a first hollow cylinder 16 disposed on the bracket 1. A first spring 17 is disposed inside the first hollow cylinder 16. A first piston disc 18 is disposed on the top of the first spring 17. A first movable rod 19 is mounted on the first piston disc 18. The top of the first movable rod 19 extends through the first hollow cylinder 16 and is connected to the movable plate 10. When the movable plate 10 moves downward, the first movable rod 19 drives the first piston disc 18 to move and squeeze the first spring 17, thereby performing adsorption and fixation work.

[0033] The second elastic component includes a second hollow cylinder 20 disposed at the bottom of the lower mold body 3, a second spring 21 disposed inside the second hollow cylinder 20, a second piston disc 22 disposed at the bottom of the second spring 21, a second movable rod 23 mounted on the second piston disc 22, and the bottom of the second movable rod 23 passing through the second hollow cylinder 20 and connecting to the third semi-circular block 14.

[0034] When the third semicircle moves, it drives the second movable rod 23 to move. The second movable rod 23 drives the second piston disc 22 to squeeze the second spring 21, thereby causing the second connecting rod 12 to drive the ejector block 13 to extend and push out the bracket 1 plate for easy removal.

[0035] The first semicircular block 5, the second semicircular block 11, and the third semicircular block 14 are all provided with smooth surfaces. The smooth surfaces can reduce friction, thereby facilitating squeezing and movement.

[0036] The working principle of this utility is as follows: First, as... Figure 2As shown, the support plate 1 is placed on the lower die body 3, and then the upper die body 2 moves downward for stamping. Before stamping, the rotating assembly is activated, which drives the first semi-circular block 5 to rotate, causing the arc surface of the first semi-circular block 5 to contact and press against the arc surface of the second semi-circular block 11. This causes the second semi-circular block 11 to drive the movable plate 10 downward and press against the first elastic component. At the same time, the movable plate 10 drives the first connecting rod 9 to move the rubber piston 8 inside the first through hole 7, thereby generating suction to fix the support plate 1 and prevent it from moving during stamping. After stamping, the upper die body 2 returns to its original position. At this time, the plane of the first arc block contacts the arc surface of the third semi-circular block 14, and the second elastic component returns to its original position. The return-to-center position drives the second connecting rod 12 to move the ejector block 13 into the limiting plate, facilitating the forming of the bracket 1. Simultaneously, the rotating component rotates in the opposite direction. At this time, the arc-shaped plate of the first semicircular block contacts the arc-shaped surface of the third semicircular block 14, causing the third semicircular block 14 to drive the second connecting rod 12 to move inside the second through hole. During the movement, the second elastic component is compressed, and the second connecting rod 12 drives the ejector block 13 to push out the formed bracket 1, making it easy to remove. When the ejector block 13 is pushed out, the plane of the first semicircular block 5 contacts the arc-shaped surface of the second semicircular block 11, and the first elastic component returns to its original position. This causes the movable plate 10 to drive the first connecting rod 9 to move the rubber piston 8 upward, thus enabling the next operation. This device can achieve stable adsorption and fixation of the bracket 1 plate during the stamping process, ensuring stamping accuracy and quality; after stamping, it can automatically eject the formed bracket 1 for easy removal, improving production efficiency.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
