Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a stamping die with a variable cavity. Background Technology

[0002] A stamping die is a tool used in metal processing, primarily for pressing metal materials into parts of the required shape or size using a stamping press. Stamping dies work together using the cooperation of a punch and a die, employing the pressure of the stamping press to perform processes such as cutting, forming, and punching.

[0003] For example, the Chinese patent with authorization announcement number CN222001429U discloses a stamping die with a variable cavity. It uses a first hydraulic telescopic column installed on the inner side of the die body to push the adjustment plate to move, thereby adjusting the width inside the die body and adjusting the die cavity. However, during the stamping process, tiny particles are generated. These particles enter the die with the movement of the operating equipment and easily adhere to the forming surface of the die or the surface of the part, causing scratches, blemishes or other defects on the product surface. Manual cleaning is required, which is slow and affects the production progress. Utility Model Content

[0004] The main objective of this invention is to provide a stamping die with a variable cavity, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-7 As shown, a stamping die with a variable cavity includes a processing table 1, a die 2 is provided on one side of the processing table 1, the die 2 has a die cavity 3, a vacuum cleaner 4 is attached to one side of the processing table 1, the output end of the vacuum cleaner 4 is connected to a first connecting pipe 5, and a flexible hose 6 is fixedly connected to one end of the first connecting pipe 5; a vacuum pipe 8 is provided on one side of the die 2, and a plurality of vacuum heads 9 are fixedly connected to one side of the vacuum pipe 8, and the plurality of vacuum heads 9 are distributed in an array at equal intervals.

[0027] In this embodiment, a second connecting pipe 7 is fixedly connected to one end of the suction pipe 8, and one end of the second connecting pipe 7 is fixedly connected to the other end of the hose 6; a moving component is provided on the mold 2, which is used to drive the suction pipe 8 to move back and forth, and a connector is provided on the suction pipe 8, which is connected to the moving component.

[0028] To prevent tiny particles from remaining inside the mold cavity 3, the suction pipe 8 is first connected to the moving component via a connector. When the vacuum cleaner 4 is started, it generates suction, which, together with the suction pipe 8 and several suction heads 9, sucks up the particles inside the mold cavity 3. The particles sucked into the suction pipe 8 are sent into the hose 6 through the second connecting pipe 7, then into the first connecting pipe 5, and finally collected by the vacuum cleaner 4, completing the cleaning of the particles inside the mold cavity 3. This prevents these particles from adhering to the forming surface of the mold or the surface of the parts, thus preventing scratches, blemishes, or other defects from appearing on the product surface. This solves the problem of slow manual cleaning by workers, improving production progress and production quality.

[0029] In this embodiment, the connector includes connecting plates 13 disposed at both ends of the suction pipe 8. Connecting plates 13 have connecting grooves 14. One end of a movable plate 12 extends into the connecting groove 14. A circular through hole is provided on one side of the movable plate 12. A spring 20 is disposed in the circular through hole. One end of the spring 20 is fixedly connected to a positioning block 19. A positioning groove 18 is provided on the connecting plate 13. One end of the positioning block 19 is inserted into the positioning groove 18.

[0030] First, insert one end of the movable plate 12 into the connecting groove 14. One end of the spring 20 in the circular through hole pushes one end of the positioning block 19 into the positioning groove 18, fixing one end of the movable plate 12 in the connecting groove 14, thereby firmly connecting the movable plate 12 and the connecting plate 13 together, completing the connection between the vacuum tube 8 and the movable component.

[0031] In this embodiment, the moving component includes two sets of fixed plates 10 disposed on the mold 2. The two sets of fixed plates 10 are provided with moving grooves 11. Moving plates 12 are slidably disposed in the moving grooves 11. The component also includes a screw 15 disposed on one side of the two sets of moving grooves 11. One end of the screw 15 passes through the fixed plate 10. A transmission component is disposed on the screw 15. One set of the two sets of fixed plates 10 is clamped to a motor 21. One set of the two sets of screws 15 is fixedly connected to the output end of the motor 21.

[0032] The motor 21 drives a set of screws 15 to rotate. The screws 15, together with the transmission component, drive another set of screws 15 to rotate. The two sets of screws 15, together with the thread, drive the moving plate 12 to slide in the moving groove 11. The moving plate 12 drives the dust suction pipe 8 to move linearly along the mold 2, which facilitates the dust suction pipe 8 to work with the dust suction head 9 to clean the particles in the mold cavity 3, thereby increasing the cleaning effect of the particles.

[0033] The transmission components include sprockets 16 mounted on two sets of screws 15, with chains 17 meshing on the two sets of sprockets 16.

[0034] One set of screws 15 rotates, which, together with the sprocket 16 and chain 17, drives another set of screws 15 to rotate, so that the two sets of screws 15 rotate at the same time. This makes it easier for the two sets of moving plates 12 to move the vacuum pipe 8, making it convenient for staff to use.

[0035] A protective shell 22 is snapped onto one side of the mold 2. The protective shell 22 covers the outside of the transmission component, protecting the transmission component from damage and thus increasing its service life.

[0036] It should be noted that this utility model is a stamping die with a variable cavity. To avoid leaving small particles inside the cavity 3, one end of the movable plate 12 is first inserted into the connecting groove 14. One end of the spring 20 in the circular through hole pushes one end of the positioning block 19 into the positioning groove 18, fixing one end of the movable plate 12 in the connecting groove 14. The movable plate 12 and the connecting plate 13 are then securely connected together, completing the connection between the suction pipe 8 and the movable component. When the vacuum cleaner 4 is started, suction is generated, and the suction pipe 8 and several suction heads 9 work together to suck up the particles inside the cavity 3. The particles entering the suction pipe 8 are sent into the hose 6 through the second connecting pipe 7, then into the first connecting pipe 5, and finally collected by the vacuum cleaner 4. At the same time, the motor 21 drives a set of screws 15 to rotate, which, together with the sprocket 16 and chain 17, drives another set of screws 15 to rotate, so that the two sets of screws 15 rotate at the same time. The two sets of screws 15, together with the threads, drive the moving plate 12 to slide in the moving groove 11. The moving plate 12 drives the suction pipe 8 to move linearly along the mold 2. The suction pipe 8, together with the suction head 9, cleans the particles in the mold cavity 3, thus completing the cleaning of the particles in the mold cavity 3.
