Description

Technical Field

[0001] This utility model relates to the field of graphics card manufacturing technology, specifically to an aluminum plate stamping and bending die. Background Technology

[0002] In the complex process of graphics card manufacturing, aluminum plate processing is one of the key steps. Since components such as the graphics card casing are often made of aluminum plates, in order to meet their specific shape and structural requirements, the aluminum plates need to be stamped to form a preliminary outline, and then precisely bent to shape a three-dimensional form that meets the design requirements.

[0003] A significant challenge in current aluminum sheet bending technology is the difficulty in automatically adjusting the aluminum sheet's position for centered bending. In actual production, due to material properties and transportation factors, the position of the aluminum sheet is often difficult to control precisely when placed on bending equipment. Existing technologies lack efficient and precise automatic positioning and adjustment mechanisms, making it impossible to quickly and accurately adjust the aluminum sheet to the appropriate position. This necessitates significant manual intervention in the centered bending process, increasing labor costs and reducing production efficiency, thus failing to meet the demands of large-scale, high-precision production. Therefore, we propose an aluminum sheet stamping and bending die. Utility Model Content

[0004] One of the technical problems this application aims to solve is that it is not easy to automatically adjust the position of the aluminum plate to achieve centering and bending.

[0005] To solve the above technical problems, this application provides an aluminum plate stamping and bending die, including a support plate and a hydraulic cylinder fixedly connected to the top of the support plate, wherein a stamping assembly is provided on one side of the support plate; The stamping assembly includes a base plate fixedly connected to one side of a support plate, a lower die fixedly connected to the top of the base plate, a stamping part provided on the top of the base plate, the stamping part including a connecting column fixedly connected to the bottom of a hydraulic cylinder, a lower pressing block fixedly connected to the bottom of the connecting column, and an upper die fixedly connected to the bottom of the lower pressing block. The lower pressure block and the upper mold are located in the middle of the connecting column, and the upper mold and the lower mold are closed together.

[0006] In some embodiments, a limiting member is provided at the bottom of the connecting column, the limiting member including a limiting rod slidably connected to the bottom of the connecting column, and a limiting block is provided at the bottom of the limiting rod; The bottom end of the limiting rod extends into the limiting block, and the bottom of the limiting block is slidably connected to the top of the base plate; The bottom of the limiting rod is set in an inclined shape, and the limiting rod is inclinedly engaged with the limiting block.

[0007] In some embodiments, a buffer member is provided inside the limiting block. The buffer member includes a buffer plate disposed inside the limiting block. A plug rod is fixedly connected to one side of the buffer plate. The plug rod is slidably inserted into the limiting block, and a spring is provided on the outer sleeve of the plug rod.

[0008] In some embodiments, an adjusting member is provided outside the connecting post. The adjusting member includes a frame fixedly connected to the outside of the connecting post. A scale is provided on the outside of the frame. An adjusting block is slidably connected inside the frame. An indicator block is fixedly connected to the outside of the adjusting block. A screw is threadedly connected inside the frame. The inner end of the screw is rotatably connected to the adjusting block. The adjusting block extends into the connecting post and is fixedly connected to a limiting rod.

[0009] This utility model has at least the following beneficial effects: By setting up a stamping assembly, in the stamping process, after one stamping operation is completed, the upper and lower dies separate. Then, the next aluminum plate to be processed is placed smoothly on the surface of the upper die. Next, the upper die begins to rise. During the rising process, the limiting blocks are linked and driven to move in opposite directions. During the movement of the limiting blocks, the aluminum plate placed on the upper die is centered and clamped. Through this series of actions, the position of the aluminum plate can be accurately and automatically adjusted to the middle position of the upper and lower dies. Thus, centering stamping can be performed automatically, reducing manual intervention, lowering labor costs, and improving production efficiency. Attached Figure Description

[0012] 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. Example 1

[0013] Please see Figures 1-5 This utility model provides a technical solution: An aluminum sheet stamping and bending die includes a support plate 1 and a hydraulic cylinder 2 fixedly connected to the top of the support plate 1. A stamping assembly 3 is provided on one side of the support plate 1, wherein: like Figure 1 , Figure 2 and Figure 5 As shown, the stamping assembly 3 includes a base plate 31 fixedly connected to one side of the support plate 1. A lower die 311 is fixedly connected to the top of the base plate 31. A stamping part 32 is provided on the top of the base plate 31. The stamping part 32 includes a connecting column 321 fixedly connected to the bottom of the hydraulic cylinder 2. A lower pressing block 322 is fixedly connected to the bottom of the connecting column 321. An upper die 323 is fixedly connected to the bottom of the lower pressing block 322. The lower pressing block 322 and the upper die 323 are located in the middle of the connecting column 321. The upper die 323 and the lower die 311 are closed. Furthermore, hydraulic cylinder 2 is activated, which drives connecting column 321, lower pressure block 322 and upper die 323 to descend, and upper die 323 and lower die 311 close together to perform stamping and bending. like Figure 2 As shown, a limiting member 33 is provided at the bottom of the connecting column 321, wherein: The limiting member 33 includes a limiting rod 331 that is slidably connected to the bottom of the connecting column 321. A limiting block 332 is provided at the bottom of the limiting rod 331. The bottom end of the limiting rod 331 extends into the limiting block 332. The bottom of the limiting block 332 is slidably connected to the top of the base plate 31. The bottom of the limiting rod 331 is set in an inclined shape. The limiting rod 331 and the limiting block 332 are inclinedly engaged. When in use, after the stamping is completed, the hydraulic cylinder 2 drives the connecting column 321, the lower pressing block 322 and the upper die 323 to rise, so that the next aluminum plate can be placed on the upper die 323. At this time, the connecting column 321 rises, which will drive the two limit rods 331 to rise, thereby driving the two limit blocks 332 to move relative to each other, aligning and clamping the aluminum plate. The position of the aluminum plate can be adjusted to the middle position of the upper die 323 and the lower die 311, and then the centering stamping is performed. Example 2

[0014] Please see Figures 1-5 This utility model provides a technical solution: Unlike Example 1, as Figure 2 and Figure 3 As shown, a buffer 34 is provided inside the limiting block 332. The buffer 34 includes a buffer plate 341 provided inside the limiting block 332. A rod 342 is fixedly connected to one side of the buffer plate 341. The rod 342 is slidably inserted into the limiting block 332. A spring 343 is provided on the outer sleeve of the rod 342. Furthermore, as the two limit blocks 332 move in the center, the two buffer plates 341 simultaneously abut against the aluminum plate, which can provide cushioning and prevent damage caused by hard contact. like Figure 4 As shown, an adjusting member 35 is provided outside the connecting post 321. The adjusting member 35 includes a frame 351 fixedly connected to the outside of the connecting post 321. A scale 352 is provided on the outside of the frame 351. An adjusting block 353 is slidably connected inside the frame 351. An indicator block 354 is fixedly connected to the outside of the adjusting block 353. A screw 355 is threadedly connected inside the frame 351. The inner end of the screw 355 is rotatably connected to the adjusting block 353. The adjusting block 353 extends into the connecting post 321 and is fixedly connected to the limiting rod 331. Furthermore, the screw 355 can be rotated to move the adjusting block 353, thereby causing the limiting rod 331 and the limiting block 332 to move synchronously. According to the indication of the indicator block 354 and the scale 352, the positions of the two sets of limiting rods 331 and limiting blocks 332 can be precisely adjusted to adapt to aluminum plates of different sizes.

[0015] Working principle: Start hydraulic cylinder 2, which drives the connecting column 321, lower pressure block 322 and upper die 323 to descend. The upper die 323 and the lower die 311 close together to perform stamping and bending. During the downward pressing process, the connecting column 321 descends and simultaneously drives the two limit rods 331 to descend. Since the bottom of the limit rods 331 is inclined, the descent of the two limit rods 331 will drive the two limit blocks 332 to move in opposite directions. Conversely, when the stamping is completed, the hydraulic cylinder 2 drives the connecting column 321, the lower pressing block 322 and the upper die 323 to rise, so that the next aluminum plate can be placed on the upper die 323. At this time, the connecting column 321 rises, which will drive the two limit rods 331 to rise, thereby driving the two limit blocks 332 to move relative to each other, aligning and clamping the aluminum plate. The position of the aluminum plate can be adjusted to the middle position of the upper die 323 and the lower die 311, and then the centering stamping is performed.
