[0028] In order to more clearly understand the technical means of the utility model, and can be implemented according to the content of the specification, the specific embodiments of the utility model are further described in detail below, the following examples are used to illustrate the utility model, but not to limit the scope of the utility model.
[0029] As Figures 1-5 Indicated, the utility model provides a shock absorber device for punch, it includes oil pressure cylinder 100, the oil pressure cylinder 100 of the utility model is a cylindrical. The oil pressure cylinder 100 top opening place is in the central shaft direction and is retracted after extending downward and forms an opening upward inner cavity 1002, then the space between the outer circumferential surface of inner cavity 1002 and the inner wall of oil pressure cylinder 100 constitutes outer cavity 1001.
[0030] The inner cavity 1002 is filled with hydraulic oil, and a first oil outlet 102 and a first oil inlet 103 are arranged at the bottom of the inner cavity 1002. A sealing flange seat 200 is fixed at the opening of the inner cavity 1002 to seal the hydraulic oil in the inner cavity 1002. The sealing flange seat 200 has a T-shaped cross section, and an annular oil outlet channel 201 is arranged on the outer periphery of the lower end of the sealing flange seat 200 in the inner cavity 1002. The annular oil outlet channel 201 is symmetrically provided with two oil outlet through holes 202. A plurality of sealing ring grooves 203 are arranged on the inner wall of the sealing flange seat 200 which is connected with the piston rod 300 and is located above the annular oil outlet channel 201, and sealing rings (not shown) are arranged in the sealing ring grooves 203 to further improve the sealing performance.
[0031] The piston rod 300 has a T-shaped cross section and is a cylindrical rod. The lower end of the piston rod 300 penetrates through the sealing flange seat 200 and is arranged in the inner cavity 1002. The piston rod 300 can slide up and down along the sealing flange seat 200, and the bottom of the piston rod 300 abuts against the bottom of the sealing flange seat 200 when the piston rod 300 slides up to the maximum stroke.

One end of the high-resilience component 301 is connected with the bottom of the piston rod 300, and the other end abuts against the bottom of the inner cavity 1002. When the piston rod 300 is pressed to descend, the high-resilience component 301 also descends synchronously. When the pressure on the piston rod 300 disappears, the high-resilience component 301 drives the reset by using the elastic deformation reaction force, and the high-resilience component 301 makes the piston rod 300 more stable during operation, further reducing the instantaneous impact force of the device.
[0033] As a preferred, the five high-strength springs are connected with the inner cavity 1002, and each of the five high-strength springs forms a spring bin independently.
