Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1, please refer to Figures 1 to 9 , this embodiment provides a hydraulic device for processing mining machinery accessories with a buffering function, including a working plate 10. A leg 1 is fixedly connected to the lower end surface of the working plate 10. A placement table 2 is also fixedly connected to the upper end surface of the working plate 10. An outer shell 8 is also fixedly connected to the upper end surface of the working plate 10. A control center 6 is also provided on the upper end surface of the outer shell 8. And a stamping assembly is arranged inside the outer shell 8. The stamping assembly includes:

[0043] The first connecting plate 15, the side surface of the first connecting plate 15 is fixedly connected to the arc surface of the arc-shaped block 18. The side surface of the first connecting plate 15 is fixedly connected to the second sliding block 16. The surface of the second sliding block 16 is slidably connected to the inner wall of the sliding frame 9. The upper end surface of the second sliding block 16 is fixedly connected to the first sliding rod 42. The surface of the first sliding rod 42 slidably penetrates the upper surface inside the outer shell 8. And the upper end surface of the first sliding rod 42 is fixedly connected to the electric push rod 5. The outer surface of the electric push rod 5 is fixedly connected to the outer surface of the outer shell 8;

[0044] The hydraulic device further includes a buffering assembly. The buffering assembly is arranged inside the outer shell 8. The buffering assembly includes:

[0045] The sliding carriage 9, the outer side surface of the sliding carriage 9 is fixedly connected to the side surface of the outer shell 8, a first sliding block 17 is slidably connected to the inner wall of the sliding carriage 9, a stamping block 4 is fixedly connected to the surface of the first sliding block 17, a stamping module 3 is fixedly connected to the lower end surface of the stamping block 4, a sliding column 20 is fixedly connected to the upper end surface of the stamping block 4, an arc-shaped block 18 is slidably connected to the surface of the sliding column 20, a first spring 19 is fixedly connected to the lower end surface of the arc-shaped block 18, and the lower end surface of the first spring 19 is fixedly connected to the upper end surface of the stamping block 4.

[0046] In this embodiment, when using this hydraulic device, place the stamping part to be stamped on the placing table 2, and then start the electric push rod 5 to drive the first sliding rod 42 to move downward. The first sliding rod 42 moves downward, thereby pushing the second sliding block 16 to move downward, driving the stamping block 4 to move downward. When the stamping block 4 moves downward and drives the stamping module 3 to contact the stamping part, the electric push rod 5 continues to drive the second sliding block 16 to move downward, thereby compressing the first spring 19 to achieve the buffering effect.

[0047] The setting of this buffering component utilizes the deformation of the first spring 19 to achieve the purpose of buffering, thereby further preventing the stamping module 3 from directly contacting the stamping part and causing damage to the stamping part or the stamping module 3.

[0048] It should be noted that in this embodiment, the hydraulic device further includes a resistance increasing component, which is arranged in the outer shell 8. The resistance increasing component includes:

[0049] A first fixing block 21, the lower end surface of the first fixing block 21 is fixedly connected to the upper end surface of the stamping block 4. A first curved rod 22 is hinged to the surface of the first fixing block 21. The upper end surface of the first curved rod 22 is hinged to an annular sliding block 23. A first fixing rod 14 is slidably connected to the inner wall of the annular sliding block 23. The end surface of the first fixing rod 14 is fixedly connected to the end surface of the arc-shaped block 18. There are two annular sliding blocks 23, and a second spring 24 is fixedly connected to the end surface of the annular sliding block 23. The other end of the second spring 24 is fixedly connected to the end surface of the other annular sliding block 23.

[0050] A first connecting rod 25, the end surface of the first connecting rod 25 is fixedly connected to the outer surface of the annular sliding block 23. A piston 26 is fixedly connected to the surface of the first connecting rod 25. The piston 26 is slidably connected to a first container 27.

The bottom end surface of the first container 27 is fixedly communicated with a first fixing pipe 28. The other end of the first fixing pipe 28 is fixedly connected to one end of the resistance self-changing component.

[0051] The second fixed pipe 29 has an end surface rotatably connected to the surface of the other end of the resistance self-changing assembly. The end surface of the second fixed pipe 29 away from the resistance self-changing assembly is fixedly communicated with a second container 31. The outer surface of the second container 31 is also fixedly connected to the upper end surface of the first connecting plate 15. A first pipe 32 is fixedly communicated with the surface of the second container 31. A blocking cover 30 is slidably connected to the upper end of the first pipe 32.

[0052] In this embodiment, as the distance between the arc-shaped block 18 and the stamping block 4 gradually decreases, the first curved rod 22 deflects, thereby pushing the two annular sliders 23 closer to each other. The annular sliders 23 not only squeeze the second spring 24 but also pull the piston 26 to move in the first container 27, so as to pump the liquid in the second container 31 into the first container 27 through the second fixed pipe 29 and the first fixed pipe 28, so as to achieve the purpose of increasing the buffer resistance by using the elastic force of the second spring 24 and the resistance of the pumped liquid flow.

[0053] The setting of this resistance increasing assembly achieves the purpose of increasing the buffer resistance by using the elastic force of the second spring 24 and the resistance of the pumped liquid flow, thereby reducing the unstable phenomenon of the spring when using the spring for buffering, and further improving the buffering stability of this buffer device during the stamping process.

[0054] Embodiment 2, on the basis of the above embodiment:

[0055] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In this embodiment, the hydraulic device includes a resistance self-changing assembly, and the resistance self-changing assembly is also arranged in the housing 8. The resistance self-changing assembly includes:

[0056] A second connecting rod 33, the end surface of the second connecting rod 33 is fixedly connected to the surface of the first connecting rod 25. A straight tooth row 34 is fixedly connected to the end surface of the second connecting rod 33 away from the first connecting rod 25. A toothed ring 35 is meshed with the tooth surface of the straight tooth row 34. The inner wall of the toothed ring 35 is fixedly connected to a rotating cover 37. A through slot is opened at the end surface of the center of the rotating cover 37. The slot wall of the slot is rotatably connected to the end surface of the second fixed pipe 29. A through strip-shaped slot 38 is opened at the end surface of the rotating cover 37. A second sliding column 36 is slidably connected to the slot wall of the strip-shaped slot 38. A shielding plate 41 is fixedly connected to the surface of the second sliding column 36.

[0057] The first fixed disk 39 has a through notch opened at the end face at the center of the first fixed disk 39. The notch wall is fixedly connected to the end surface of the first fixed pipe 28. The end face of the first fixed disk 39 facing away from the first fixed pipe 28 is provided with a hexagonal groove 40. The groove wall of the hexagonal groove 40 is slidably connected to the end surface of the second sliding column 36 away from the rotating cover 37, and the surface of the first fixed disk 39 is slidably connected to the inner wall of the rotating cover 37.

[0058] In this embodiment, by moving the two annular sliders 23 closer to each other, the second connecting rod 33 is driven to move, and then the toothed ring 35 is rotated through the straight tooth row 34, and then the rotating cover 37 is rotated. The rotation of the rotating cover 37 can drive the second sliding column 36 to slide in the strip-shaped groove 38 and the hexagonal groove 40, so as to drive the six shielding plates 41 to move, thereby reducing the diameter of the channel between the first fixed pipe 28 and the second fixed pipe 29, indirectly increasing the resistance of the liquid flow, and thus increasing the resistance during buffering. After the stamping is completed, the first spring 19 and the second spring 24 recover to drive the second connecting rod 33 and the straight tooth row 34 to recover, so that the toothed ring 35 rotates in reverse, and the six shielding plates 41 are driven to move in the same way, thereby increasing the diameter of the channel between the first fixed pipe 28 and the second fixed pipe 29 to reduce the liquid flow resistance and facilitating the recovery of the first spring 19 and the second spring 24;

[0059] The setting of this resistance self-changing component changes the diameter of the channel between the first fixed pipe 28 and the second fixed pipe 29, thereby changing the resistance of the liquid flow, so as to automatically change the magnitude of the resistance according to the magnitude of the buffering force during the stamping process, so as to adapt to different positions of the stamping module 3 on the stamping part. When stamping into the stamping part, the force required by this buffering device is greater, the buffering effect is more stable, and the buffering process is also more stable. When recovery is required, it can recover faster, thereby improving the accuracy of this stamping device when stamping the stamping part.

[0060] Embodiment 3, on the basis of the above embodiment:

[0061] Please refer to Figure 2 , in this embodiment, the hydraulic device further includes a safety protection component. The safety protection component is arranged on the housing 8, and the safety protection component includes:

[0062] The second fixed block 11, the surface of the second fixed block 11 is fixedly connected to the side surface of the stamping block 4. A second curved rod 12 is hinged on the surface of the second fixed block 11. The other end of the second curved rod 12 is hinged to a protection plate 7. One end of the protection plate 7 is hinged to a second fixing plate 13, and the end face of the second fixing plate 13 is fixedly connected to the outer surface of the sliding frame 9.

[0063] In this embodiment, the electric push rod 5 drives the stamping block 4 to move downward, thereby driving the second curved rod 12 to move, rotating the protection plate 7 around the hinge of the second fixed plate 13 as the axis, so as to push aside the things around the stamping part, thereby improving the safety of this hydraulic device during the stamping process and reducing the possibility of accidents during the operation.

[0064] Working principle: When this hydraulic device for processing mining machinery accessories with a buffering function is in use, it has the following steps:

[0065] S1: Place the stamping part to be stamped on the placement table 2, and then start the electric push rod 5 to drive the first sliding rod 42 to move downward, thereby driving the stamping block 4 to move downward;

[0066] S2: The downward movement of the stamping block 4 drives the second curved rod 12 to move, rotating the protection plate 7 around the hinge of the second fixed plate 13 as the axis, so as to push aside the things around the stamping part;

[0067] S3: Then the stamping block 4 moves downward until the stamping module 3 touches the surface of the stamping part. After that, the distance between the arc-shaped block 18 and the stamping block 4 gradually decreases to utilize the first spring 19 for buffering;

[0068] S4: During the buffering process, it will also drive the first curved rod 22 to deflect, thereby pushing the annular sliders 23 to approach each other and compress the second spring 24, and driving the piston 26 to move in the first container 27, so as to pump the liquid in the second container 31 into the first container 27 through the second fixed pipe 29 and the first fixed pipe 28,

[0069] S5: During the movement of the annular sliders 23, it will also adjust the diameter of the channel between the first fixed pipe 28 and the second fixed pipe 29 according to the distance that the stamping module 3 enters the stamping part, so as to adjust the resistance during buffering, and thus make it move more stably when inside the stamping part and improve the accuracy of stamping.
