Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the following description of the embodiments is only for the purpose of helping understanding the principle and the core idea of the present invention, and is not intended to limit the scope of the present invention. It should be noted that modifications to the present invention may occur to those skilled in the art without departing from the principles of the present invention and are intended to fall within the scope of the appended claims.

Examples

The buckle sponge gasket punching mechanism comprises a male die 13 and a female die 6 for punching a sponge gasket 5, wherein the male die 13 is arranged on a male die holder 9, the female die 6 is arranged on a female die holder 18, the male die holder 9 and the female die holder 18 can be fixed on a support, and a first air cylinder 14 is adopted to drive the male die holder 9 and the male die 13 to synchronously move downwards so that the male die 13 is matched with the female die 6 to realize the punching of the sponge gasket 5, as shown in fig. 1 and 2.

In this embodiment, a pressing plate 8 is disposed below the male die holder 9, a spring 11 is disposed between the pressing plate 8 and the male die holder 9, the spring 11 is connected to the pressing plate 8 and the male die holder 9, specifically, grooves are disposed on the upper portion of the pressing plate 8 and the lower portion of the male die holder 9, and the two grooves cooperate to form a space for accommodating the spring 11; after the sponge washer 5 is punched, the pressing plate 8 is driven by the reset elastic force of the spring 11 to continuously press the sponge washer 5. A first guide column 12 is arranged on the press plate 8 and the convex die holder 9 in a penetrating way, and the spring 11 is sleeved on the first guide column 12.

In this embodiment, a lock plate 4 is disposed below the die holder 18, a material ejecting member 7 is disposed on the lock plate 4, and the material ejecting member 7 is movably sleeved on or inserted through the die 6. And a second air cylinder 17 for driving the locking plate 4 and the ejection piece 7 to synchronously lift is arranged below the locking plate 4. The ejection part 7 adopts a hollow ejection cylinder or an arc-shaped ejector plate, and when the arc-shaped ejector plate is used, each ejection part 7 can be formed by combining two arc-shaped ejector plates which are symmetrically arranged.

In this embodiment, the press plate 8 is provided with a second guide post 1, and the die holder 18 is provided with a guide hole 2 engaged with the guide post 1.

In this embodiment, two first guide posts 12 and two second guide posts 1 are respectively arranged, and two second guide posts 1 are simultaneously located between the two first guide posts 12.

In the embodiment, the male die 13 is a hollow cylinder, and the outer diameter of the hollow cylinder is matched with that of the sponge washer 5; the female die 6 is a solid cylinder, and the outer diameter of the solid cylinder is matched with the inner diameter of the sponge gasket 5; the outer diameter and the inner diameter of the jacking piece 7 are both between the outer diameter and the inner diameter of the sponge gasket 5.

In this embodiment, a neck bolt 10 is disposed between the adjacent first guide post 12 and the second guide post 1, a small diameter portion of the neck bolt 10 is located in the pressing plate 8, the pressing plate 8 can axially slide along the small diameter portion of the neck bolt 10, and the large diameter portion of the neck bolt 10 penetrates through the die holder 9.

When the die is used, when the sponge cushion base material is positioned between the pressing plate 8 and the female die 6, the first air cylinder 14 drives the male die holder 9, the male die 13 and the pressing plate 8 to synchronously move downwards, so that the pressing plate 8 compresses the sponge cushion base material, and the lower end of the male die 13 is close to the upper end of the female die 6 and compresses the sponge cushion base material, so that the die cutting can be realized; at the moment after the punching is finished, the first air cylinder 14 drives the male die holder 9 and the male die 13 to ascend synchronously, the pressing plate 8 drives the pressing plate 8 to continuously press the sponge gasket 5 through the reset elastic force of the spring 11, and the pressing plate 8 is separated from the sponge gasket 5 again after the male die holder 9 and the male die 13 ascend to a proper height.
