[0051] The pressing piston rod 38 can reciprocate, lift and slide during the reciprocating forging process, and can continuously drive the hydraulic push rod 13 to slide through hydraulic transmission, thereby realizing the sliding of the sliding rack 28 and the elastic force storage of the energy storage torsion spring 26, thereby achieving the technical purpose of driving the hollow transmission sleeve 25 to lift and flip.

[0054] By lifting and sliding the lifting sleeve 41, different liquid flow modes can also be controlled, thereby automatically controlling the unidirectional drive and reflux of the liquid.

[0055] The adaptive lifting mechanism 1 includes a lifting assembly 5 and a transverse driving assembly 6 . The lifting assembly 5 is arranged on a forging base 51 , and the transverse driving assembly 6 is arranged on the lifting assembly 5 .

[0056] The adaptive lifting mechanism 1 can automatically control the lifting and lowering of the energy storage type turning mechanism 2 at a specific time by unlocking the locking hook rod 55, thereby achieving the technical effect of turning over the tooling and the workpiece after multiple forgings.

[0057] The lifting assembly 5 includes a guide base 7, a lifting bearing seat 8, a rising spring 9, a cantilever top frame 10 and a locking hook rod 55. The guide base 7 is arranged on the forging base 51. Guide rods 16 are symmetrically provided on both sides of the guide base 7. Guide collars 17 are symmetrically provided on both sides of the lifting bearing seat 8. The lifting bearing seat 8 is slidably arranged on the guide rod 16 through the engagement of the guide collar 17. The rising spring 9 is arranged between the bottom of the guide rod 16 and the guide collar 17. A bearing mounting hole 18 is provided in the middle position of the lifting bearing seat 8. A ramp groove 19 is also provided on the lifting bearing seat 8. The cantilever top frame 10 is fixedly connected to the top of the lifting bearing seat 8. The bottom of the locking hook rod 55 is fixedly connected to the guide base 7. The top of the locking hook rod 55 is provided with a top triangular hook 56 that cooperates with the ramp groove 19.

[0058] The locking hook rod 55 is made of elastic material.

[0059] In the initial state, the top triangular hook 56 can hook the lifting bearing seat 8 to limit the position of the lifting bearing seat 8. After the hydraulic push rod 13 moves laterally beyond a certain range, that is, when the top triangular hook 56 is pushed to shift laterally, the lifting bearing seat 8 can be unlocked through the cooperation of the ramp groove 19 and the top triangular hook 56.

[0060] The transverse driving assembly 6 includes a hydraulic cylinder seat 11, a hydraulic cylinder body 12, a hydraulic push rod 13, an end slide 14 and an unlocking lever 15. The hydraulic cylinder seat 11 is fixedly connected to the cantilever top frame 10, the hydraulic cylinder body 12 is fixedly connected to the hydraulic cylinder seat 11, the hydraulic push rod 13 is slidably arranged in the hydraulic cylinder body 12, the end slide 14 is fixedly connected to the end of the hydraulic push rod 13, the unlocking lever 15 is arranged on the end slide 14, and the end of the unlocking lever 15 is provided with a triangular boss 20 matching the top triangular hook 56.

[0061] The position of the sliding rack 28 can be controlled by the telescopic movement of the hydraulic push rod 13. On the one hand, the energy storage torsion spring 26 can be deformed and store elastic force through the rotation of the hollow transmission sleeve 25. On the other hand, the lifting bearing seat 8 can be unlocked.

[0062] The energy storage type turning mechanism 2 comprises a turning type tooling assembly 21 and a one-way drive type energy storage assembly 22 . The turning type tooling assembly 21 is arranged in the lifting assembly 5 , and the one-way drive type energy storage assembly 22 is arranged on the lifting assembly 5 .

[0063] The lateral sliding of the energy storage flipping mechanism 2 can drive the rotation of the cylindrical tooling 24. When the cylindrical tooling 24 does not rise, it will only store elastic potential energy through the deformation of the valve changing assembly 36. After the lifting bearing seat 8 is unlocked, the cylindrical tooling 24 will flip in the opposite direction.

[0064] The flip tooling assembly 21 includes a flip bearing 23, a cylindrical tooling 24, a hollow transmission sleeve 25 and an energy storage torsion spring 26. The flip bearing 23 is snap-fitted in the bearing mounting hole 18. Flip support shafts 30 are symmetrically arranged on both sides of the cylindrical tooling 24. The flip support shaft 30 is snap-fitted in the flip bearing 23. A limit ring 31 is arranged on the flip support shaft 30. The hollow transmission sleeve 25 is rotatably arranged on the flip support shaft 30. The energy storage torsion spring 26 is located in the hollow transmission sleeve 25. The energy storage torsion spring 26 is sleeved on the flip support shaft 30. One end of the energy storage torsion spring 26 is fixedly connected to the flip support shaft 30, and the other end of the energy storage torsion spring 26 is fixedly connected to the hollow transmission sleeve 25.

[0065] The resistance to the rotation of the flip support shaft 30 in the lifting bearing seat 8, and the rotation resistance between the hollow transmission sleeve 25 and the flip support shaft 30, are both greater than the deformation resistance between the external ratchet 32 ​​and the internal ratchet 34. Therefore, in the stage of sliding reset of the sliding rack 28, the hollow transmission sleeve 25 and the flip support shaft 30 will remain stationary, and the sliding rack 28 will be allowed to reset only by the rotation of the transmission gear 29.

[0066] The one-way driven energy storage assembly 22 includes a sliding support plate 27, a sliding rack 28 and a transmission gear 29. The sliding support plate 27 is fixedly connected to the lifting bearing seat 8. The sliding rack 28 is provided with a central slide groove 33. The sliding rack 28 is slidably arranged on the sliding support plate 27 through the central slide groove 33. The transmission gear 29 is rotatably arranged on the hollow transmission sleeve 25. The hollow transmission sleeve 25 is provided with an external ratchet 32. The transmission gear 29 is provided with an internal ratchet 34 matching the external ratchet 32. The transmission gear 29 and the sliding rack 28 are meshed for transmission.

[0067] During specific use, the connector 48 is connected to the external liquid storage tank through a hose. First, the user needs to place the parts inside the cylindrical tooling 24. In the initial state, the lifting bearing seat 8 is locked at the bottom limit position by the top triangular hook 56, and then the forging hammer 53 is lifted and lowered reciprocatingly by controlling the reciprocating extension and contraction of the forging hydraulic cylinder 52, thereby realizing the forging processing of the parts.

[0068] When the forging hammer 53 descends, the liquid inlet pressing rod 54 will also contact and press the pressing piston rod 38 downward, and when the pressing piston rod 38 is pressed downward, the transmission fluid in the liquid supply cylinder 37 can be delivered to the hydraulic cylinder body 12 through the linkage joint 43 and the hydraulic hose 44; when the forging hammer 53 rises and resets, the pressing piston rod 38 also rises and resets under the elastic force of the reset spring 39, and sucks the liquid in the external liquid storage tank into the liquid supply cylinder 37;

[0069] Due to the presence of the one-way valve 40, during the reciprocating lifting and lowering process of the forging hammer 53, the liquid in the external liquid storage tank is continuously transported to the hydraulic cylinder body 12 through the transfer of the liquid supply cylinder 37, thereby pushing the hydraulic push rod 13 to extend; when the hydraulic push rod 13 extends, it slides with the unlocking lever 15 and the sliding rack 28 at the same time through the end slide plate 14;

[0070] The sliding of the sliding rack 28 can drive the transmission gear 29 to rotate, and the transmission gear 29 drives the hollow transmission sleeve 25 to rotate through the cooperation of the internal ratchet 34 and the external ratchet 32. At this time, since the lifting bearing seat 8 is locked at the bottom limit position, the flip support shaft 30 cannot rotate. Therefore, the hollow transmission sleeve 25 stores elastic potential energy through the elastic deformation of the energy storage torsion spring 26 during rotation.

[0071] The hydraulic push rod 13 continues to extend and the unlocking lever 15 continues to slide. When the triangular boss 20 hooks the top triangular hook 56 and bends the top triangular hook 56 horizontally, the top triangular hook 56 is placed in the slope groove 19. At this time, the top triangular hook 56 can no longer lock the lifting bearing seat 8. The lifting bearing seat 8 will rise with the cylindrical fixture 24 under the elastic force of the lifting spring 9. After the cylindrical fixture 24 rises, the cylindrical fixture 24 will rotate half a circle under the elastic force of the energy storage torsion spring 26 because the forging base 51 has lost its restriction on the cylindrical fixture 24.

[0072] After the elastic force of the energy storage torsion spring 26 is released, the cylindrical tooling 24 and the workpiece inside it are turned over.

[0073] Moreover, since the lifting bearing seat 8 lifts up and the restriction on the reset lever 50 is released, the lifting sleeve 41 will slowly rise under the elastic force of the return spring 42, and the joint 1 48 and the joint 2 49 will be changed from the position of being combined with the one-way hole 46 to the position of being combined with the through hole 45. At this time, since there is no restriction of the one-way valve 40, and the hydraulic cylinder body 12 is provided with a spring for resetting the hydraulic push rod 13, under the elastic force of this spring, the hydraulic push rod 13 will be reset together with the end slide 14, the unlocking lever 15 and the sliding rack 28, and the transmission fluid in the hydraulic cylinder body 12 will flow back to the external liquid storage tank;

[0074] During the reset stage of the sliding rack 28, since the resistance to the rotation of the flip support shaft 30 in the lifting bearing seat 8 and the rotation resistance between the hollow transmission sleeve 25 and the flip support shaft 30 are both greater than the deformation resistance between the external ratchet 32 ​​and the internal ratchet 34, during the sliding reset stage of the sliding rack 28, the hollow transmission sleeve 25 and the flip support shaft 30 will remain stationary, and the sliding rack 28 will be allowed to reset only by the rotation of the transmission gear 29.

[0075] During the next downward pressing process of the forging hammer 53, the external pressing plate extending from the forging hammer 53 can bring the lifting bearing seat 8 down again by squeezing the cantilever top frame 10, and the lifting bearing seat 8 is locked again by the top triangular hook 56;

[0076] At the same time, when the lifting bearing seat 8 is lowered, the lifting sleeve 41 can be lowered as a whole by pressing down the reset lever 50, and the joint 1 48 and the joint 2 49 can be changed from the position combined with the through hole 45 to the position combined with the one-way hole 46.

[0077] Through the above movement, the periodic turning of the workpiece can be automatically completed during the process of the forging hammer head 53 reciprocatingly forging the workpiece.

[0078] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
