[0003] However, the traditional punching mechanism only contacts the material sheet before punching during the punching process. Before punching, the elasticity of the material sheet will cause the internal gasket to be skewed during punching, thereby affecting the processing effect of the gasket. After the processing is completed, the gasket will remain in the mold due to its own tension, and the material removal step is more troublesome, affecting the discharge efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-7 The utility model provides a technical solution: a speaker gasket punching mechanism, including a table 1, a punching cylinder 2 is provided on the upper end of the table 1, a movable plate 3 is fixedly connected to the output end of the punching cylinder 2, a lower die 4 is fixed on the upper end of the table 1, an upper die 6 is fixed on the lower end of the movable plate 3, a slot 5 is provided on the upper end of the lower die 4, a die-cutting head 7 is fixed on the lower end of the upper die 6, the slot 5 and the die-cutting head 7 are matched and arranged correspondingly, a pressing mechanism is provided on the lower end of the upper die 6, and the pressing mechanism is arranged correspondingly to the upper end surface of the lower die 4, and a discharging mechanism is provided on the inner side of the lower end of the lower die 4. The material mechanism is set corresponding to the slot hole 5; when punching the gasket, the entire gasket is placed on the lower die 4, and the upper die 6 moves downward, and the die-cutting head 7 punches the entire gasket. The punched finished gasket is located in the slot hole 5. Before punching, the entire piece of material is pressed by the clamping mechanism to provide a more stable placement. When the movable plate 3 rises, the punched material is removed, and the finished gasket in the slot hole 5 is blown out by the discharging mechanism, so that the gasket floats on the upper end surface of the lower die 4, thereby avoiding the gasket being restricted in the slot hole 5, and making it easier for the operator to take out the gasket.

[0024] like Figure 3As shown, the clamping mechanism includes: a pressing plate 9, which is arranged between the die cutting heads 7, and the upper end of the pressing plate 9 is fixedly connected to a first spring 8, and the upper end of the first spring 8 is fixedly connected to the upper die 6. A groove 10 is provided on the upper die 6, and the pressing plate 9 is matched with the groove 10; a pressing ring 13, which is arranged below the upper die 6, and the four corners of the upper end of the pressing ring 13 are fixedly connected to a second spring 12, and the upper end of the second spring 12 is fixedly connected to the lower end of the upper die 6, and a guide rod 11 is passed through the second spring 12, and the guide rod 11 is arranged through the pressing ring 13, and the guide rod 11 is connected to the lower die 4 is pierced with corresponding settings at the four corners of the upper die 6; when the upper die 6 moves downward, the pressure plate 9 presses the material sheet, and during the continuous downward pressure, the pressure plate 9 shrinks into the groove 10 through the contraction of the first spring 8. At this time, the pressure plate 9 is located in the groove 10, and the end face is flush with the lower end face of the upper die 6. Before this, the pressure ring 13 first contacts the outer ring of the material sheet, and the material sheet is first fixed and pressed as a whole, thereby achieving a stable effect. As the upper die 6 moves, the second spring 12 contracts, and the guide rod 11 passes through the pressure ring 13 and is inserted into the four corners of the lower die 4, thereby achieving a stable movement effect.

[0025] like Figure 5 and Figure 6 As shown, the discharging mechanism includes: an air pipe 14, one end of the air pipe 14 is connected to the air source, and the other end is divided into three branches and is arranged in the lower mold 4. The air pipe 14 is connected to an air ring 15, and the upper end of the air ring 15 is fixed with an air head 16, which passes through the lower mold 4 and is arranged in the slot 5; the air pipe 14 is supplied with air through the air source, and after punching, the air pipe 14 is inflated through the connection of the air ring 15, and the air rushes out from the air head 16, and the gasket is pushed upward when rushing out. When the gasket falls, it falls on the lower mold 4 by its own gravity, and can no longer fall completely into the slot 5, which makes it convenient for the operator to take the material.

[0026] like Figure 7 As shown, a sealing sheet 17 is fixedly connected to the inner side of the upper end of the air head 16, and the sealing sheet 17 is divided into four petals. When no air is injected, the sealing sheets 17 are pressed against each other to achieve a sealing effect, thereby avoiding the impact of punching and cutting on the use of the air head 16. When air is injected, the sealing sheet 17 can be opened to achieve the effect of discharging.

[0027] like Figure 6 As shown, there are three gas heads 16, and the spacing between the gas heads 16 is equal; the gas heads 16 are arranged in a triangular arrangement, so that the gasket can be fully flushed and Figure 5 It can be seen intuitively that the positions of the air head 16 and the connecting end of the slot 5 correspond to each other. The contact surface here is the largest, so the friction force is the largest, which makes it easier for the gasket to be discharged.

[0028] like Figure 4As shown, the pressing plate 9 is arranged in a square shape, and the four corners of the pressing plate 9 are arranged in a circular shape; the pressing plate 9 is arranged in a square shape, which can occupy a larger area, and the four corners of the pressing plate 9 are arranged in a circular shape, so that the pressing and fixing can be performed with the largest area.

[0029] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
