Description

Technical Field

[0001] This utility model relates to the field of laminated metal plate processing technology, and in particular to a laminated metal plate embossing device. Background Technology

[0002] Laminated metal sheets, with their combination of metal strength and film functionality (such as corrosion resistance and decorative properties), are widely used in home appliance manufacturing, building decoration and electronic device housings, and embossing is a key process to enhance their appearance and practical performance.

[0003] However, in the embossing process of laminated metal plates, the precise fixing of the metal plate is the core link to ensure the embossing accuracy and film integrity. The existing metal plate clamping scheme of the embossing device has significant shortcomings. The traditional single-sided clamping method causes the metal plate to shift laterally during the embossing process due to the imbalance of force, which directly causes texture misalignment and film edge tearing. Therefore, a laminated metal plate embossing device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a metal plate embossing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal plate embossing device includes a base plate, on which multiple supports are fixedly mounted. A common placement platform is fixedly connected to the top of each support. An adsorption assembly is located below the placement platform. A mounting frame is fixedly mounted on the top of the base plate, and an embossing assembly is mounted on the mounting frame. Two fixed brackets are fixedly mounted on the top of the base plate. Each fixed bracket has a circular hole on its opposite face, and a threaded rod is installed within each hole. The two threaded rods have opposite screw directions. The ends of the two threaded rods that are far apart are rotatably connected to the inner walls of one side of each fixed bracket. The ends of the two threaded rods that are close together are fixedly connected to a first bevel gear and a second bevel gear. A transmission assembly is located on one side of the first bevel gear and the second bevel gear. A clamping assembly is located on the outer side of each threaded rod.

[0007] Preferably, the adsorption assembly includes a placement platform with a through hole, an adsorption plate fixedly installed in the through hole, a vacuum pump fixedly installed on the bottom side of the base plate, a vacuum tube fixedly installed on the top side of the vacuum pump, and the other end of the vacuum tube passing through the base plate and fixedly connected to the inside of the adsorption plate.

[0008] Preferably, the embossing assembly includes a cylinder fixedly mounted on the top side of the mounting frame, the output end of the cylinder passing through the mounting frame and fixedly connected to a connecting plate, and two slots opened on the bottom side of the connecting plate, with insert blocks inserted into each of the two slots.

[0009] Preferably, the bottom sides of the two inserts are fixedly connected to the same embossed plate, with the embossed plate facing the placement platform. The embossed plate and the connecting plate are respectively provided with threaded grooves and threaded holes. A threaded post is installed in the threaded hole, and the other end of the threaded post is threaded into the threaded groove that is aligned with the threaded hole.

[0010] Preferably, the transmission assembly includes a motor fixedly mounted on one side of the mounting frame, the output end of the motor rotating through the mounting frame and fixedly connected to a transmission bevel gear, the transmission bevel gear meshing with a first bevel gear and a second bevel gear respectively.

[0011] Preferably, the clamping assembly includes two threaded rods, each with a slider threaded onto its outer side. A set of fixing rods is fixedly installed on the top side of each slider. Each set of fixing rods consists of two rods. Clamping plates are fixedly connected to the opposite surfaces of the two sets of fixing rods, and the two clamping plates are arranged symmetrically.

[0012] Preferably, a connecting frame is fixedly installed on the top side of the base plate. The connecting frame is U-shaped, and a guide rod is fixedly installed inside the connecting frame. One side of each of the two sliders is slidably sleeved on the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The motor drives the transmission bevel gear, which in turn drives the reverse threaded rod to rotate via the first and second bevel gears. This causes the threaded slider to tighten the clamping plate synchronously, clamping the metal plate from both sides. At the same time, the vacuum pump and vacuum tube under the placement platform form an adsorption assembly. When embossing thin plates, the vacuum mode can be switched to use negative pressure to adsorb and fix the metal plate. This dual-mode fixing method avoids the lateral displacement caused by traditional single-sided clamping, prevents texture misalignment and film tearing, and provides a stable foundation for embossing.

[0015] 2. The embossing operation is completed by the vertical movement of the connecting plate and the embossing plate driven by the cylinder. The embossing plate is fixed by the insertion of the insert block and the slot, combined with the threaded post, which makes it easy to quickly change the embossing plate with different patterns.

[0021] 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.

[0022] Reference Figure 1-4A metal plate embossing device includes a base plate 1. Multiple supports 2 are fixedly mounted on the top side of the base plate 1. A common placement platform 3 is fixedly connected to the top side of the supports 2. An adsorption assembly is disposed below the placement platform 3. A mounting frame 7 is fixedly mounted on the top side of the base plate 1, and an embossing assembly is disposed on the mounting frame 7. Two fixed brackets 14 are fixedly mounted on the top side of the base plate 1. Circular holes are opened on the opposite surfaces of the two fixed brackets 14, and threaded rods 15 are disposed within each of the two circular holes. The threads of the two threaded rods 15 have opposite directions. The ends of the two threaded rods 15 that are far apart from each other are rotatably connected to the inner walls of one side of the two fixed brackets 14. A first bevel gear 16 and a second bevel gear 17 are fixedly connected to the ends of the two threaded rods 15 that are close to each other. A transmission assembly is disposed on one side of the first bevel gear 16 and the second bevel gear 17. Clamping assemblies are disposed on the outer sides of the two threaded rods 15. The transmission assembly includes a motor 23 fixedly mounted on one side of the mounting frame 7, and the output end of the motor 23 rotatably passes through... The mounting bracket 7 is fixedly connected to a transmission bevel gear 24, which meshes with the first bevel gear 16 and the second bevel gear 17. The motor 23 drives the transmission bevel gear 24 to rotate clockwise. Because the transmission bevel gear 24 meshes with the first bevel gear 16 and the second bevel gear 17, the first bevel gear 16 and the second bevel gear 17 will drive the threaded rod 15 connected to them to rotate synchronously under the meshing transmission of the transmission bevel gear 24. Since the two threaded rods 15 have opposite screw directions, when the motor 23 drives the transmission bevel gear 24 to rotate clockwise, the sliders 20 with threads on the outer sides of the two threaded rods 15 will move closer to each other, so that the clamping plate 22 above the two sliders 20 can securely clamp the metal plate. By clamping the metal plate, it is possible to prevent the metal plate from shifting during the embossing process. The vacuum pump 5 can also be started during the mechanical clamping process, thereby achieving multiple fixation of the metal plate.

[0023] Specifically, the adsorption assembly includes a placement platform 3 with a through hole, an adsorption plate 4 fixedly installed inside the through hole, a vacuum pump 5 fixedly installed on the bottom side of the base plate 1, and a vacuum tube 6 fixedly installed on the top side of the vacuum pump 5. The other end of the vacuum tube 6 passes through the base plate 1 and is fixedly connected to the inside of the adsorption plate 4. By setting up the vacuum pump 5, when a thin metal plate needs to be processed, the vacuum mode can be switched, the vacuum pump 5 is started, and air is drawn out through the vacuum tube 6 on the surface of the placement platform 3 to quickly form a negative pressure environment. Atmospheric pressure tightly adsorbs the metal plate onto the placement platform. The adsorption plate 4 made of silicone material can ensure airtightness and make the adsorption force act evenly on the plate surface. This non-contact fixing method avoids the damage caused by rigid clamping to thin plates and films, and provides a stable foundation for high-precision embossing.

[0024] Specifically, the embossing assembly includes a cylinder 8 fixedly mounted on the top side of the mounting bracket 7. The output end of the cylinder 8 passes through the mounting bracket 7 and is fixedly connected to a connecting plate 9. Two slots 10 are provided on the bottom side of the connecting plate 9, and inserts 11 are inserted into each of the two slots 10. The bottom side of the two inserts 11 is fixedly connected to the same embossing plate 12, which faces the placement platform 3. The embossing plate 12 and the connecting plate 9 are respectively provided with threaded grooves and threaded holes. A threaded post 13 is threaded into the threaded hole, and the other end of the threaded post 13 is threaded into the threaded groove aligned with the threaded hole. By providing the cylinder 8, after the metal plate is fixed, starting the cylinder 8 will drive the embossing plate 12 below the connecting plate 9 to move towards the metal plate. As the embossing plate 12 continues to move downwards, the embossing process on the metal plate can be completed. Since the embossing plate 12 is inserted into the two slots 10 of the connecting plate 9 by two inserts 11, when it is necessary to replace the embossing plate 12 with a different pattern, simply remove the threaded post 13 from the connecting plate 9, and then pull the embossing plate 12 outwards to remove the two inserts 11 from the two slots 10. After removal, the embossing plate 12 with a different pattern can be replaced. During installation, simply insert the two inserts 11 into the two slots 10. After the inserts 11 are inserted, the threaded groove on the top side of the embossing plate 12 will be aligned with the threaded hole on the connecting plate 9. At this time, the threaded post 13 can be used again for fixation.

[0025] Specifically, the clamping assembly includes two threaded rods 15, each with a slider 20 threadedly sleeved on its outer side. A set of fixing rods 21 is fixedly installed on the top side of each slider 20, with two rods in each set. Clamping plates 22 are fixedly connected to the opposite faces of the two sets of fixing rods 21, and the two clamping plates 22 are symmetrically arranged. A connecting frame 18 is fixedly installed on the top side of the base plate 1. The connecting frame 18 is U-shaped, and a guide rod 19 is fixedly installed inside the connecting frame 18. One side of each slider 20 is slidably sleeved on the guide rod 19. With two sliders 20, under the action of the transmission assembly, the two sliders 20 will drive the two sets of fixing rods 21 to move closer to each other, thereby enabling the two clamping plates 22 to firmly clamp both sides of the metal plate. The guide rod 19 guides and limits the movement of the two sliders 20, allowing them to move stably.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0027] In use: First, place the coated metal plate to be embossed flat on the placement platform 3. Start the motor 23, and its output shaft drives the transmission bevel gear 24 to rotate clockwise. Since the transmission bevel gear 24 is meshed with the first bevel gear 16 and the second bevel gear 17 respectively, under the meshing transmission of the transmission bevel gear 24, the threaded rod 15, which is coaxially fixed with the first bevel gear 16 and the second bevel gear 17, begins to rotate synchronously. Because the two threaded rods 15 adopt a reverse thread design, when the motor 23 drives the transmission bevel gear 24 to rotate clockwise, the slider 20, which is threaded onto the outside of the threaded rod 15, will move towards each other along the guide rod 19 under the transmission principle of the screw nut. As the two sliders 20 approach each other, the clamping plate 22 fixed above the sliders 20 gradually tightens, and the two sides are synchronously clamped. The method of fixing the metal plate stably in the center of the placement platform effectively prevents displacement caused by uneven force during the embossing process. The device also adopts a dual-mode fixing scheme of vacuum adsorption and mechanical clamping. When processing such thin plates, the mechanical clamping mechanism can be turned off and the vacuum pump 5 can be started. The vacuum tubes 6 distributed on the surface of the placement platform 3 form a negative pressure adsorption force field, which can tightly adhere the metal plate to the adsorption platform and avoid indentations or deformations that may be caused by rigid clamping. After the fixing process is completed, the cylinder 8 is started. The cylinder piston rod drives the connecting plate 9 to move vertically downward. The embossing plate 12 fixed below the connecting plate 9 then approaches the metal plate. As the embossing plate 12 is continuously pressed down under the driving force of the cylinder, the preset pattern on its surface will be accurately imprinted on the surface of the metal plate through plastic deformation process, and finally the texture processing is completed.
