Description

Technical Field

[0001] This application relates to the technical field of buffering, and in particular to a buffering device. Background Technology

[0002] During the production process, track pads need to be stamped. During the stamping process, a buffer device is required. However, the existing buffer device has large fluctuations in oil pressure, which easily generates vibration and noise. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide a buffer device that has the advantage of reducing oil fluctuations.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A buffer device includes a buffer mechanism and an energy storage mechanism. The buffer mechanism includes a cylinder with a piston inside, which divides the cylinder into a first chamber and a second chamber. The energy storage mechanism includes a buffer tank. The first chamber and the buffer tank are connected. The second chamber and the buffer tank are connected via a one-way valve. The one-way valve is directed to flow unidirectionally into the cylinder. The first chamber and the second chamber are connected via a damping flow channel.

[0005] By adopting the above technical solution, during use, when the piston rod moves toward the second chamber, the oil in the second chamber enters the first chamber from the damping channel, and the oil in the first chamber enters the buffer tank. During this process, the fluctuation of the oil is more stable.

[0006] In a preferred embodiment, this application may be further configured such that: the buffer bucket is further provided with a buffer assembly, the buffer assembly and the inner wall of the buffer bucket form a receiving cavity, and the cavity and the connection point of the buffer bucket are located at the receiving cavity.

[0007] By adopting the above technical solution, the presence of the buffer component can effectively buffer the oil entering the buffer tank.

[0008] In a preferred embodiment, the present application may be further configured such that: the buffer assembly includes a buffer plate, the buffer plate is made of an elastic material, the buffer plate is disposed below the connection between the second cavity and the buffer tank, and the medium entering the buffer tank from the first cavity will contact the buffer plate.

[0009] By adopting the above technical solution, the buffer plate, being made of elastic material, will deform when subjected to impact, thus providing a buffering effect.

[0010] In a preferred embodiment, the present application may be further configured such that the buffer assembly also includes a side plate, which is installed at the bottom of the buffer bucket and connected to the buffer plate for supporting the buffer plate.

[0011] By adopting the above technical solution, the presence of the side plate enables the buffer plate to be supported.

[0012] In a preferred embodiment, this application may be further configured such that: the side plate is provided with a liquid inlet hole, the lowest point of which is located above the bottom surface inside the buffer tank.

[0013] By adopting the above technical solution, the presence of the liquid inlet hole makes it less likely for the liquid to carry impurities into the receiving cavity when entering the receiving cavity.

[0014] In a preferred embodiment, the present application may be further configured such that the buffer assembly includes a baffle disposed within the receiving cavity and located between the liquid inlet and the cavity and the buffer tank.

[0015] By adopting the above technical solution, the presence of the baffle further enhances the ability to remove impurities.

[0016] In a preferred embodiment, this application may be further configured such that the damping channel is provided with a through hole, the diameter of which is smaller than the diameter of the damping channel.

[0017] By adopting the above technical solution, the diameter of the guide hole is smaller than the diameter of the damping channel, thus enabling linear pressure change.

[0018] In a preferred embodiment, this application may be further configured such that a conductive element is detachably connected to the damping channel, and the conductive hole is disposed on the conductive element.

[0019] By adopting the above technical solution, the desired damping effect can be achieved by replacing different conductive components during use.

[0020] In a preferred embodiment, this application can be further configured as follows: there are two sets of guiding channels, namely channel A and channel B, with one end of channel A disposed on the piston and one end of channel B disposed on the inner wall of cavity two.

[0021] By adopting the above technical solution, namely by setting up flow channel A, the gas in cavity two can be discharged during use.

[0022] In a preferred embodiment, this application can be further configured such that one end of the flow channel B on cavity one and the connection point between cavity one and the buffer tank are on the same horizontal plane.

[0023] By adopting the above technical solution, when the piston rod moves upward during use, the liquid in chamber one will enter chamber two through flow channel B. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 The present application discloses a buffer device, which includes a buffer mechanism and an energy storage mechanism. The buffer mechanism includes a cylinder 1, and a piston 13 is provided inside the cylinder 1. The piston 13 divides the interior of the cylinder 1 into a first cavity 11 and a second cavity 12. The energy storage mechanism includes a buffer tank 3. The first cavity 11 and the buffer tank 3 are connected. The second cavity 12 and the buffer tank 3 are connected through a one-way valve. The one-way valve conducts unidirectionally toward the inside of the cylinder 1. The first cavity 11 and the second cavity 12 are connected through a damping flow channel. There are two sets of flow channels, namely flow channel A22 and flow channel B21. One end of flow channel A22 is set on piston 13 and is equipped with a one-way valve. The flow direction is towards the outside. One end of flow channel B21 is set on the inner wall of cavity 2 12, and the other end is set on cavity 11 and is at the same level as the connection between cavity 11 and buffer tank 3. A connecting element 4 is detachably connected to the damping flow channel. The connecting element 4 is provided with a connecting hole 41. The connecting hole 41 is a conical hole, that is, the hole diameter gradually decreases in the direction towards the outside. In other embodiments, the damping flow channel can also be a conical hole, that is, the hole diameter gradually decreases in the direction towards the outside.

[0029] In this embodiment, the one-way valves are all small balls (such as steel balls). For example, the one-way valve at the flow channel A22 is a small ball set at the conductor 4 in the flow channel A22, and the one-way valve at the connection between cavity 2 12 and buffer tank 3 is a small ball set at the connection between the two in cavity 2 12.

[0030] Cavity 11 and buffer tank 3 are connected by a guide pipe 31 extending into the oil inside buffer tank 3. Buffer tank 3 is also provided with a buffer assembly 32, and the buffer assembly 32 and the inner wall of buffer tank 3 form a receiving cavity 325. The connection between cavity 12 and buffer tank 3 is located at the receiving cavity 325.

[0031] The buffer assembly 32 includes a buffer plate 321, a side plate 322, and a baffle 324. The side plate 322 is installed at the bottom of the buffer tank 3 and connected to the buffer plate 321 to support the buffer plate 321. The buffer plate 321 and / or the side plate 322 are made of elastic material. The buffer plate 321 is located below the connection between the cavity 12 and the buffer tank 3, that is, the outlet of the guide pipe 31 is located above the buffer plate 321. In the horizontal projection, the projection of the buffer plate 321 covers the projection of the outlet of the guide pipe 31. The medium entering the buffer tank 3 from the cavity 11 will come into contact with the buffer plate 321.

[0032] The side plate 322 is provided with a liquid inlet hole 323. The lowest point of the liquid inlet hole 323 is located above the bottom surface inside the buffer tank 3. The baffle 324 is provided in the receiving cavity 325 and is located between the liquid inlet hole 323 and the cavity 12 and the buffer tank 3.

[0033] The implementation principle of this embodiment is as follows: When the press table presses the piston 13 rod to move towards the bottom of the cylinder, the volume of the second chamber 12 decreases, and the oil damping channel flows into the first chamber 11. At the same time, some oil enters the buffer tank 3 through the guide pipe 31. As the piston 13 approaches the bottom of the cylinder, due to the existence of the damping channel, the oil flow rate decreases and the buffering force increases. The buffer disc spring is compressed synchronously to further absorb the impact energy. During the reset, oil enters the second chamber 12, the piston 13 moves in the opposite direction, the oil in the buffer tank 3 flows back, and the disc spring resets.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
