Detailed ways

Example:

As shown in Figure 1, Figure 2 and Figure 3, the air cushion shock absorber provided in this embodiment includes a structural main body, which consists of an upper cover plate 1, a lower cover plate 2, and upper and lower cover plates (1, 2) It consists of an air cushion structure 3 between the outer edges of the air cushion structure 3 and the upper and lower cover plates (1, 2) at the four corner support positions including dampers 4.

The upper cover plate 1 is made of iron plate, and the middle position of the upper cover surface of the upper cover plate 1 includes a circular nut connection opening 5 . The air cushion structure 3 is composed of an air chamber 6 and an air filling port 7 connected to the side. Described lower cover plate 2 is made up of iron plate and rubber plate. The damper 4 includes a damping cylinder 8 fixed on the lower cover 2, the damping cylinder 8 is provided with a damping cover 9, and the damping cover 9 communicates with a piston rod 10 in the middle, and the piston rod 10 is connected to the upper cover 1. The lower deck support connection. The damping cylinder 8 is respectively provided with a hydraulic cylinder and an oil storage cylinder. The number of the 4 dampers is the same as the number of support angles between the upper cover plate 1 and the lower cover plate 2 .

The main technical principle of this embodiment is as follows:

Pneumatic anti-vibration device, combined with the design of hydraulic damping cylinder 8, can effectively eliminate impact vibration and meet the needs of the highest speed punching machine; adopt low natural frequency design, good anti-vibration effect, good weather resistance and long service life, oil-proof Cap design, with oil resistance to prevent general oil corrosion, internal design damping mechanism can effectively avoid resonance phenomenon, natural frequency 3Hz-5Hz, damping coefficient 0.12-0.13.
