[0001] An elastic buffer device belongs to the technical field of buffer equipment. Background Art

[0002] Explosion ultra-high pressure bimetal welding composite usually involves loosening the soil, then laying a base plate on the soil, laying steel balls on the upper side of the base plate and then laying a clad plate, laying explosives on the upper side of the clad plate, and setting a detonator at one end of the explosives. After the detonator ignites the explosives, the steel balls at the positioning intervals are extruded between the clad plate and the base plate, and the clad plate and the base plate are welded and compounded into one body to form a composite plate.

When the metal plates are compounded next time, it is necessary to re-place the flexible protection wall, and the placement efficiency of the protection wall is low, which leads to low production efficiency of the bimetal plates and is very inconvenient to operate.

[0018] The following further describes the present utility model with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the drawings is for better explanation, and the structure of the present utility model necessarily goes beyond these limited embodiments. For some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of the present application.

[0019] Figure 1 It is the best embodiment of the present utility model. The following further describes the present utility model with reference to the attached Figure 1 drawings.

[0020] An elastic buffer device, comprising a buffer column 1, a buffer cylinder body 2 and a reset assembly. The buffer cylinder body 2 is a cylinder with an open top. The buffer column 1 is a hollow cylinder. The lower end of the buffer column 1 can slide into the buffer cylinder body 2. A seal is provided between the buffer column 1 and the buffer cylinder body 2. A communication hole 7 is provided at the lower end of the buffer column 1 to communicate the buffer cylinder body 2 with the inner cavity of the buffer column 1. Hydraulic oil is provided in the buffer cylinder body 2. The reset assembly is provided between the buffer cylinder body 2 and the buffer column 1. When this elastic buffer device is impacted, the buffer column 1 will be compressed into the buffer cylinder body 2. During this process, the hydraulic oil in the buffer cylinder body 2 is squeezed by the buffer column 1 and will flow into the buffer column 1 through the communication hole 7, thereby realizing the buffering of the buffer column 1 through the hydraulic oil. After the explosion is completed, the reset assembly pushes the buffer column 1 to reset, and the hydraulic oil flows back into the buffer cylinder body 2 due to the action of gravity, realizing the automatic reset of this elastic buffer device, so that it is possible to buffer the next explosion composite of the bimetal plate without additional work, realizing the buffering of the bimetal plate explosion composite in a short time and making the production efficiency of the bimetal plate explosion composite high.

[0021] Specifically, as Figure 1 shown: In this embodiment, the reset assembly is a buffer spring 3. The buffer spring 3 is provided in the buffer cylinder body 2 and is located between the buffer cylinder body 2 and the buffer column 1.

[0022] Hydraulic oil is provided in the buffer cylinder body 2, and a communication hole 7 is provided at the lower end of the buffer column 1. The communication hole 7 communicates the inner cavity of the buffer column 1 with the inner cavity of the buffer cylinder body 2. When an explosion occurs, the impact generated by the explosion will push the buffer column 1 to slide into the buffer cylinder body 2. At this time, the buffer spring 3 buffers the movement of the buffer column 1, and at the same time, the hydraulic oil in the buffer cylinder body 2 enters the buffer column 1 through the communication hole 7. Since the hydraulic oil has a certain viscosity and it takes a certain time and pressure for it to flow into the buffer column 1, a buffering effect is achieved.

[0023] There is a space between the buffer column 1 and the inner wall of the buffer cylinder body 2. A ring-shaped convex platform with a diameter larger than that of the buffer column 1 is provided at the bottom of the buffer column 1, and there is a gap between the ring-shaped convex platform and the inner wall of the buffer cylinder body 2.

[0024] A guide ring 5 is provided at the upper mouth part of the buffer cylinder body 2. The guide ring 5 is fixedly connected to the buffer cylinder body 2, and the guide ring 5 can ensure the stability of the up and down movement of the buffer column 1.

[0025] In this embodiment, a plurality of partition plates 6 are arranged at intervals along the height direction in the buffer column 1, thereby forming a plurality of buffer cavities in the buffer column 1. A plurality of communication holes 7 are provided on each partition plate 6, so as to be able to communicate the adjacent two buffer cavities, thereby realizing multi-stage buffering. The diameter of the communication hole 7 at the bottom is larger than the diameter of the adjacent communication hole 7 above.

[0026] In order to ensure the sealing performance between the buffer cylinder body 2 and the buffer column 1, a sealing ring 4 is arranged between the buffer cylinder body 2 and the buffer column 1. In this embodiment, two sealing rings 4 are arranged side by side and at intervals, and the two sealing rings 4 are fixedly installed on the inner wall of the buffer cylinder body 2 from top to bottom, so as to ensure the sealing effect.

[0027] A plurality of elastic buffer devices are combined to form a large-area buffer body for the production of large-format bimetallic explosive cladding.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. 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 technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
