Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , a punching processing device for aluminum product production, including a punching table 1 with a support structure at the bottom, and the support structure is a support leg 3 installed on the lower surface of the punching table 1, which is used to support the punching table 1 to a suitable height through the support leg 3 to facilitate the staff to punch the aluminum plate.

[0021] A punch hole 2 is provided at the center of the punching table 1, and two side plates 5 with supporting functions are symmetrically installed at both ends of the upper surface of the punching table 1. A cross plate 6 is fixedly connected between the top ends of the two side plates 5, and a cylinder 7 is fixedly connected to the upper surface of the cross plate 6. A multi-stage piston rod 8 is installed on the cylinder 7, and the bottom end of the multi-stage piston rod 8 passes through the cross plate 6 and is slidably connected to the cross plate 6. The bottom end of the multi-stage piston rod 8 is detachably connected to a punch 11 opposite to the punch hole 2 through a connecting structure. When in use, the aluminum plate to be punched can be placed on the punching table 1, and the position of the aluminum plate is adjusted so that the position where the hole is to be opened in the aluminum plate is aligned with the punch hole 2. At this time, the cylinder 7 installed on the cross plate 6 can be started, and the multi-stage piston rod 8 is pushed to extend by the cylinder 7, thereby driving the punch 11 installed on the bottom end of the multi-stage piston rod 8 to move downward, and the aluminum plate is punched.

[0022] A movable plate 13 is fixedly connected to the bottom multi-stage piston rod 8. Both ends of the movable plate 13 are provided with guide devices, which are used to guide the movable plate 13 during movement to avoid displacement of the movable plate 13 as much as possible.

[0023] The movable plate 13 is symmetrically provided with two adjusting devices along the central axis of the multi-stage piston rod 8, a sliding tube 18 is fixedly connected to the lower surface of the adjusting device, a sliding rod 19 is slidably connected to the bottom end of the sliding tube 18, one end of the sliding rod 19 located in the inner cavity of the sliding tube 18 is fixedly connected to a spring 20, and one end of the sliding rod 19 located outside the sliding tube 18 is fixedly connected to a pressure plate 21, and when the spring 20 is in an extended state, the bottom height of the pressure plate 21 is lower than the bottom height of the punch 11.

[0024] For details, please refer to Figure 1 A U-shaped plate with two ends fixedly connected to the lower surface of the punching table 1 is fixedly connected below the punching table 1, a drawer 4 is slidably connected in the inner cavity of the U-shaped plate, and the punch hole 2 is connected to the inner cavity of the drawer 4. The drawer 4 is installed below the punch hole 2 to collect the aluminum sheets produced by punching after falling through the punch hole 2.

[0025] For details, please refer to Figure 1 The inner diameter of the punch hole 2 is equal to the outer diameter of the punch 11, and the inner diameter of the top end of the punch hole 2 gradually increases to the inner diameter of the bottom end of the punch hole 2. The inner diameter of the top end of the punch hole 2 to the inner diameter of the bottom end of the punch hole 2 is set to gradually increase, which can avoid the aluminum sheet from being stuck in the inner cavity of the punch hole 2 as much as possible, affecting the subsequent collection of the aluminum sheet.

[0026] For details, please refer to Figure 2, the connecting structure includes a joint 9 fixedly connected to the bottom end of the multi-stage piston rod 8. A threaded hole 10 is provided in the center of the joint 9. A threaded rod 12 is fixedly connected to the top end of the punch 11. The punch 11 is screwed to the threaded hole 10 through the threaded rod 12. The joint 9 and the threaded rod 12 are provided to screw the punch 11 onto the bottom end of the multi-stage piston rod 8. The screwed connection method not only provides a firm connection but also facilitates the installation and replacement of the punch 11.

[0027] Specifically, please refer to Figure 1 , the guiding device includes guiding grooves 14 provided on the adjacent side walls of two side plates 5, and further includes guiding blocks 15 fixedly connected to both ends of the movable plate 13 and embedded in the guiding grooves 14 and slidably connected to the side plates 5 through the guiding grooves 14. When the movable plate 13 moves up and down along the height direction of the side plates 5, the movement path of the movable plate 13 can be guided through the guiding grooves 14 and the guiding blocks 15, and the deviation of the movable plate 13 during the movement can be minimized.

[0028] Specifically, please refer to Figure 2 , the adjusting device includes two adjusting holes 16 symmetrically provided on the movable plates 13 on both sides of the multi-stage piston rod 8. Adjusting blocks 17 are slidably connected in both of the two adjusting holes 16. The top end of the sliding tube 18 is fixedly connected to the lower surface of the adjusting block 17. The adjusting holes 16 and the adjusting blocks 17 are provided to adjust the position of the clamping structure composed of the sliding tube 18, the sliding rod 19, the spring 20 and the pressing plate 21 installed below the adjusting block 17 to adapt to clamping and fixing aluminum sheets of different sizes.

[0029] Specifically, refer to Figure 3 , the bottom height of the sliding tube 18 is higher than the bottom height of the punch 11. When the spring 20 is in a compressed state, the bottom end of the punch 11 moves downward and inserts into the inner cavity of the punch hole 2. It can minimize the problem that the punch 11 cannot be inserted into the inner cavity of the punch hole 2 due to the supporting effect of the spring 20 or the sliding tube 18 during the downward movement of the punch 11 pushed by the cylinder 7, resulting in the inability to punch the aluminum plate.

[0030] Working principle: When in use, the user first places the aluminum plate to be punched on the punching table 1 and adjusts the position of the aluminum plate so that the position where the aluminum plate needs to be perforated is aligned with the punch hole 2. At this time, the air cylinder 7 installed on the cross plate 6 can be started. The multi-stage piston rod 8 is pushed by the air cylinder 7 to extend, thereby driving the punch 11 installed at the bottom end of the multi-stage piston rod 8 to move downward. Since the bottom height of the pressing plate 21 is lower than the bottom height of the punch 11, during the downward movement of the punch 11, the pressing plate 21 first fits with the aluminum plate, and cooperates with the punching table 1 below to clamp and fix the aluminum plate. At the same time, since the spring 20 can be compressed and contracted, after the pressing plate 21 presses and fixes the aluminum plate, the punch 11 can continue to move downward under the pushing action of the multi-stage piston rod 8 to punch the aluminum plate, thus avoiding the problem that the existing punching device needs to be adjusted multiple times before punching the aluminum plate, with complex operations and greatly affecting the punching efficiency of the aluminum plate.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
