Specific embodiments

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present utility model are not limited.

[0023] A stamping device for a display screen mold, as Figures 1 - 5 shown, includes a frame 1, a support frame 2, a hydraulic cylinder 3, a lifting frame 4, an upper stamping die 6, a lower stamping die 12 and a handling mechanism. A support frame 2 is fixedly connected to the top of the frame 1, a hydraulic cylinder 3 is fixedly connected to the top of the support frame 2, the bottom of the piston rod of the hydraulic cylinder 3 is fixedly connected to the lifting frame 4, an upper stamping die 6 is provided at the bottom of the lifting frame 4, a lower stamping die 12 is fixedly connected to the top of the frame 1, the lower stamping die 12 is located directly below the upper stamping die 6, and a handling mechanism is fixedly connected to the rear side of the top of the frame 1; the handling mechanism includes a support plate 13, a horizontal long cylinder 14, a vertical long cylinder 15 and an electromagnetic chuck 16. A horizontal long cylinder 14 is fixedly connected to the top of the support plate 13, a vertical long cylinder 15 is fixedly connected to the piston rod of the horizontal long cylinder 14, and an electromagnetic chuck 16 is fixedly connected to the piston rod of the vertical long cylinder 15.

[0024] At first, both the horizontal long cylinder 14 and the vertical long cylinder 15 in the handling mechanism are in a contracted state. When it is necessary to stamp and form a metal plate, place the metal plate at the rear side of the top of the frame 1. Start the vertical long cylinder 15 to move the electromagnetic chuck 16 downward to adsorb the metal plate, and then use the vertical long cylinder 15 to move the electromagnetic chuck 16 upward to lift the metal plate. Start the horizontal long cylinder 14 to move the vertical long cylinder 15 on it forward so that the metal plate is located above the lower stamping die 12. Then, use the vertical long cylinder 15 to move the electromagnetic chuck 16 downward. After the electromagnetic chuck 16 places the metal plate on the lower stamping die 12, the vertical long cylinder 15 moves the electromagnetic chuck 16 upward. The horizontal long cylinder 14 moves the vertical long cylinder 15 backward to move away from the lower stamping die 12. After the handling mechanism resets, start the hydraulic cylinder 3 to move the upper stamping die 6 downward through the lifting frame 4, so that the upper stamping die 6 contacts and presses the metal plate with the lower stamping die 12. Then, start the hydraulic cylinder 3 to move the upper stamping die 6 upward, and then take out the processed metal plate. Thus, the stamping of the metal plate is completed. The metal plate is placed in the stamping die for processing through the handling mechanism, eliminating the need for manual placement of the metal plate on the lower stamping die 12, reducing the danger of this device.

[0025] As Figure 1 and Figure 3 shown, it also includes an adjusting screw 5. The upper stamping die 6 is slidably connected to the bottom of the lifting frame 4. The lifting frame 4 is rotatably connected with an adjusting screw 5, and the adjusting screw 5 is threadedly connected to the upper stamping die 6. By rotating the adjusting screw 5, the upper stamping die 6 can move up and down in the lifting frame 4. Adjusting the upper stamping die 6 can reduce the gap when it is in close contact with the lower stamping die 12, preventing unqualified stamping of the metal plate due to insufficient closing height and ensuring the stamping quality of this device.

[0026] As Figures 1 - 4 shown, it also includes guide rods 8, first connecting rods 9, second connecting rods 10 and a movable plate 11. Two movable plates 11 are slidably connected to the top of the lower stamping die 12. The two movable plates 11 are symmetrically arranged front and back. The left and right sides of the rear movable plate 11 are rotatably connected with first connecting rods 9 respectively. The left and right sides of the front movable plate 11 are rotatably connected with second connecting rods 10 respectively. The two first connecting rods 9 are rotatably connected to the second connecting rods 10 on the same side respectively. The left and right sides of the lifting frame 4 are slidably connected with guide rods 8 respectively. The bottoms of the guide rods 8 are fixedly connected to the connection points of the first connecting rods 9 and the second connecting rods 10 on the same side respectively. Cylindrical protrusions are provided in the middle of the guide rods 8.

[0027] At first, the two movable plates 11 move away from each other. When the lifting frame 4 moves downward, the cylindrical convex block of the guide rod 8 will contact the lifting frame 4. Through the first connecting rod 9 and the second connecting rod 10, the two movable plates 11 move closer to each other and clamp the metal plate. When the lifting frame 4 moves upward, the lifting frame 4 will drive the guide rod 8 to reset, so that through the first connecting rod 9 and the second connecting rod 10, the two movable plates 11 move away from each other and loosen the metal plate. Finally, the processed metal plate is taken out. The movable plate 11 can clamp the metal plate to prevent the metal plate from shifting after falling off the electromagnetic chuck 16, which may cause the normal stamping operation of the metal plate to be impossible, and avoid affecting the processing accuracy and productivity of this device.

[0028] As Figures 1 - 3 shown, it also includes a support spring 7. A support spring 7 is fixedly connected between the cylindrical convex block of the guide rod 8 and the lifting frame 4. When the lifting frame 4 moves downward, the lifting frame 4 will compress the support spring 7 and then make the guide rod 8 move downward. When the lifting frame 4 moves upward, the lifting frame 4 will make the support spring 7 stretch. The support spring 7 can play a buffering role, prevent the lifting frame 4 and the guide rod 8 from being worn by friction, and can protect the lifting frame 4 and the guide rod 8.

[0029] As Figures 1 - 4 shown, a through hole is opened at the top of the frame 1. When the metal plate is being stamped, a large amount of waste will be generated, and the waste will fall from the through hole at the top of the frame 1, avoiding the waste affecting the stamping operation of the metal plate and keeping this device clean.

[0030] As Figure 1 shown, it also includes a waste collection box 17. The waste collection box 17 is slidably connected to the middle of the frame 1. At first, the waste collection box 17 is located directly below the through hole of the frame 1. After the waste falls from the through hole of the frame 1, it will fall into the waste collection box 17. When the waste collection box 17 is full of waste, the waste collection box 17 is pulled out, and then the waste in the waste collection box 17 is cleaned to prevent the waste from polluting the workshop and keep the workshop clean.

[0031] As Figure 1 shown, handles are fixedly connected to both the front and rear sides of the waste collection box 17. When moving the waste collection box 17, hold and move the handle to drive the waste collection box 17 to move, so that the movement of the waste collection box 17 can be made easier.

[0032] As Figure 1 and Figure 4As shown in the figure, a handling mechanism is installed on the front side of the top of the frame 1, and the two handling mechanisms are symmetrically arranged front and back. After the metal plate is stamped, the processed metal plate is taken out from the lower stamping die 12 by the front handling mechanism on the frame 1, and the processed metal plate can be placed on the front side of the top of the frame 1, making it more convenient to take out the processed metal plate, preventing injuries when manually taking out the metal plate, improving the safety of the device, and the integration of putting in and taking out the metal plate can reduce labor costs and improve the stamping efficiency of the device.

[0033] As Figures 1 - 4 shown in the figure, buffer pads are provided on the opposite sides of the movable plates 11. When the movable plates 11 approach each other to clamp the metal plate, the buffer pads can protect the metal plate, prevent the metal plate from being scratched by the movable plates 11, avoid waste of the metal plate, and reduce unnecessary losses.

[0034] As Figures 1 - 4 shown in the figure, square grooves are opened on both the front and back sides of the top of the frame 1. When the metal plate needs to be placed on the top of the frame 1, the metal plate is placed in the square groove on the back side of the top of the frame 1, and then the back handling mechanism is used to move the metal plate to the lower stamping die 12, which can improve the efficiency and accuracy of the handling mechanism, and thus further improve the stamping efficiency of the device.

[0035] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation mode of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
