Abstract

The invention discloses a buffering mechanism of a hydraulic machine, and belongs to the technical field of buffering mechanisms. The buffering mechanism of the hydraulic machine comprises a machine base, supporting columns and sliding plates, and the supporting columns are fixedly connected to the upper end of the machine base. The sliding plate is slidably connected with the supporting columns,a plurality of liquid grooves are formed in the machine base, supporting rods are slidably connected into the liquid grooves, a liquid storage cavity is formed in the machine base, a plurality of liquid pipes are connected to the liquid storage cavity, the ends, away from the liquid storage cavity, of the liquid pipes are connected with the liquid grooves, and connecting pipes are connected to theliquid pipes. Through the supporting rods, the liquid grooves, the liquid pipes, the connecting pipes, a first stop ball and the like, the purpose of preventing the supporting rods from entering theliquid storage cavity and moving downwards is achieved, through a liquid inlet pipe, a second stop ball, a second spring, an annular groove and a clamping block, the supporting rods are further prevented from moving downwards, it is guaranteed that the sliding plates are prevented from impacting the machine base, and a pull rod is prevented from being used.

Example Embodiment

[0027] Example 1:

[0028] refer to Figure 1-5 , a hydraulic press buffer mechanism, including a machine base 1, a support column 2, a slide plate 3, the support column 2 is fixedly connected to the upper end of the machine base 1, the slide plate 3 is slidably connected to the support column 2, and multiple groups of liquid tanks 5 are arranged in the machine base 1 , the support rod 4 is slidably connected in the liquid tank 5, the base 1 is provided with a liquid storage chamber 7, and a plurality of groups of liquid pipes 6 are connected to the liquid storage chamber 7, and the end of the liquid pipe 6 far away from the liquid storage chamber 7 is connected to the liquid tank 5 connected, the liquid pipe 6 is connected with a connecting pipe 9, the liquid pipe 6 is slidingly connected with a first stop ball 10, and the end of the liquid pipe 6 close to the connecting pipe 9 is fixedly connected with a stopper 12, and the stopper 12 and the first stopper A first spring 11 is arranged between the balls 10, and the two ends of the first spring 11 are respectively fixedly connected with the stop block 12 and the first stop ball 10.

[0029] In order to buffer the hydraulic machine, this device is equipped with multiple sets of support rods 4 on the machine base 1. When the slide plate 3 moves down steadily to make the pressure plate 20 contact with the support rods 4, the support rods 4 are slowly lowered under the extrusion of the slide plate 3. Due to the stable pressure in the liquid tank 5, the liquid in the liquid tank 5 enters the liquid pipe 6 through the connecting pipe 9, and then enters the liquid storage chamber 7 through the liquid pipe 6. Since the liquid flows through the stable and smooth route, the support The force exerted by the rod 4 on the skateboard 3 is small, reducing the influence on the work of the skateboard 3;

[0030] When the slide plate 3 reaches the end of the stroke, because the pressure plate 20 suddenly loses the load, the slide plate 3 will suddenly accelerate downwards to impact the workbench. Since the pressure plate 20 is attached to the support rod 4, the pressure plate 20 drives the support rod 4 to accelerate and move downward. , and then make the support rod 4 impact the liquid in the liquid tank 5, so that the pressure in the liquid tank 5 suddenly rises, the high-pressure liquid pushes the first stop ball 10 to slide, the first spring 11 is compressed, and the first stop The ball 10 blocks the connecting port between the connecting pipe 9 and the liquid pipe 6 to prevent the liquid from flowing into the liquid storage chamber 7, and the pressure of the liquid reacts to the support rod 4 to prevent the support rod 4 from falling, and at the same time, the high-pressure liquid pushes the second blocking ball 13 moves, and the second spring 14 is compressed, and because the second retaining ball 13 moves, the pressure in the annular groove 15 increases, and then pushes the clamp block 16 and the support rod 4 to be closely attached to each other, further preventing the support rod 4 from moving down, Furthermore, the impact of the slide plate 3 on the machine base 1 can be avoided.

[0031] Example 2:

[0032] refer to Figure 1-5 , a hydraulic press buffer mechanism, which is basically the same as that of Embodiment 1, furthermore: the connecting pipe 9 is connected with a liquid inlet pipe 8, the upper end of the liquid tank 5 is provided with an annular groove 15, and a clamp block 16 is slidably connected in the annular groove 15 , the clamp block 16 is attached to the support rod 4, the end of the liquid inlet pipe 8 away from the connecting pipe 9 is connected to the annular groove 15, the second stop ball 13 is slidably connected to the liquid inlet pipe 8, and the second stop ball 13 is fixedly connected There is a second spring 14, and the end of the second spring 14 away from the second stop ball 13 is fixedly connected with the liquid inlet pipe 8, so as to further ensure the support stability of the support rod.

Example Embodiment

[0033] Example 3:

[0034] refer to Figure 1-5 , a buffer mechanism for a hydraulic press, which is basically the same as in Embodiment 1, furthermore: a pair of clamping blocks 16 are slidably connected in the annular groove 15, and a third spring 17 is fixedly connected between the pair of clamping blocks 16, wherein A clip 16 is attached to the support rod 4. When the third spring 17 is compressed, under the action of the elastic force of the third spring 17, the clip 16 close to the support rod 4 is closely attached to the support rod 4, further play a buffer role.
