Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-Figure 5 The utility model discloses a multi-station hydraulic press, comprising a hydraulic press 1 and a hydraulic rod 2, the hydraulic rod 2 being mounted on the top surface of the inner wall of the hydraulic press 1, an extrusion plate 3 being mounted on the bottom surface of the hydraulic rod 2, a telescopic rod 4 being mounted on the top surface of the inner wall of the hydraulic press 1, a rotating plate 5 being mounted on the top surface of the inner wall of the hydraulic press 1, a gear 6 being mounted on one side surface of the rotating plate 5, a fixing component being mounted on the top surface of the inner wall of the hydraulic press 1, and a driving component being mounted on one side surface of the hydraulic press 1.

[0025] There are three hydraulic rods 2, which are equidistantly distributed on the bottom surface of the inner wall of the hydraulic press 1, and an extrusion plate 3 is installed on the bottom surface of each hydraulic rod 2. There are twelve telescopic rods 4, each four of which are equidistantly distributed on the top surface of the inner wall of the hydraulic press 1, and the bottom surface of the telescopic rod 4 is connected to the top surface of the extrusion plate 3. There are four rotating plates 5, which are equidistantly distributed on the top surface of the inner wall of the hydraulic press 1, and a gear 6 is distributed on one side surface of each rotating plate 5.

[0026] The fixing component includes a rotating groove 7, a reinforcing rod 8 is installed on one side surface of the gear 6, a deflection plate 9 is installed on the inner wall of the reinforcing rod 8, a suction cup 10 is installed on the bottom surface of the deflection plate 9, a counterweight block 11 is installed on the outer surface of the suction cup 10, and an air pipe 12 is installed on the top surface of the suction cup 10. The rotating groove 7 is opened on the top surface of the inner wall of the hydraulic press 1.

[0027] There are four rotating grooves 7 equidistantly distributed on the top surface of the inner part of the hydraulic press 1, there are four reinforcing rods 8, and the four reinforcing rods 8 are respectively distributed on one side surface of the four gears 6, there are two deflection plates 9, and the outer surface of each deflection plate 9 is interconnected with the inner walls of the two reinforcing rods 8, and the deflection plates 9 are movably and rotatably connected to the inner walls of the reinforcing rods 8. A suction cup 10 is correspondingly distributed on the inner wall of each deflection plate 9, and a counterweight block 11 is correspondingly distributed on the outer surface of each suction cup 10, and an air pipe 12 is correspondingly distributed on the top surface of each suction cup 10, and the air pipe 12 is connected to the inner wall of the suction cup 10.

[0028] When the reinforcing rod 8 rotates, the counterweight 11 controls the deflection plate 9 to be always in a horizontal state, so that the bottom surface of the suction cup 10 can always be at the same level with the top surface of the metal plate through rotation. When the suction cup 10 contacts the top surface of the metal plate due to the rotation of the reinforcing rod 8, the air pump starts and generates a strong suction force through the suction cup 10. At this time, the suction cup 10 will adsorb the metal plate on its bottom surface due to the suction force, thereby achieving temporary fixation.

[0029] Embodiment 2

[0030] Based on the above Example 1, please refer to Figure 6 , Figure 7The driving assembly includes a protective shell 13, a driving motor 14 is mounted on one side surface of the protective shell 13, a screw rod 15 is mounted on one side surface of the driving motor 14, a ball slider 16 is mounted on the outer side surface of the screw rod 15, a driving plate 17 is mounted on one side surface of the ball slider 16, a latch 18 is mounted on the bottom end surface of the driving plate 17, and the protective shell 13 is mounted on one side surface of the hydraulic press 1.

[0031] There are two protective shells 13 , which are respectively distributed on one side and the other side of the hydraulic press 1 . A driving motor 14 is installed on one side of each protective shell 13 , and a lead screw 15 is correspondingly distributed at the output end of each driving motor 14 .

[0032] There are two drive plates 17, and two ball sliders 16 are distributed on one side surface of each drive plate 17. The inner wall of the ball slider 16 is movably and rotatably connected to the outer surface of the screw rod 15. A plurality of latch teeth 18 are distributed on the bottom end surface of each drive plate 17, and the latch teeth 18 are meshed with the gear 6.

[0033] When the reinforcing rod 8 rotates negative 180 degrees, the suction cup 10 drives the fixed metal plate to move to another hydraulic station. When the movement is completed, the air pump stops starting, so that the metal plate falls to the top surface of another station, realizing the transportation and movement of the processed metal plate after the processing is completed. When the movement is completed, the driving motor 14 is started again, and the reinforcing rod 8 is rotated to the initial position through the rotation of the gear 6, so as to facilitate the next stamping of the metal plate.

[0034] The working principle and use process of the utility model are as follows: when a multi-station hydraulic press is needed, the air pipe 12 interconnected with the suction cup 10 is connected to the air pump, and the metal plate to be processed is placed on the top surface of the inner wall of the hydraulic press 1, and the metal plate is located on the bottom surface of the extrusion plate 3. When the placement is completed, the hydraulic rod 2 is started. When the hydraulic rod 2 is started, the extrusion plate 3 installed on its bottom surface is driven to move downward. When the extrusion plate 3 moves downward, the telescopic rod 4 connected to its top surface is driven to contract. The extrusion plate 3 is placed by contracting the multiple telescopic rods 4. When the hydraulic rod 2 drives the extrusion plate 3 to move downward, the metal plate is extruded through the extrusion plate 3. When the metal plate is extruded, it will deform, thereby realizing stamping. When the stamping is completed, the two drive motors 14 are started. When the drive motor 14 is started, the screw rod 15 installed at its output end is driven to rotate, and the outer surface of the screw rod 15 is sleeved with a ball slider 16. At this time, because the rotation of the screw rod 15 causes the ball slider 16 to drive the drive plate 17 installed on one side of the surface to move, the bottom surface of the drive plate 17 is installed with a latch 18, and the latch 18 The gear 6 is meshed with each other, so when the driving plate 17 moves, the gear 6 will be pushed to rotate on one side surface of the rotating plate 5 through the latch teeth 18, and a reinforcing rod 8 is installed on one side surface of the gear 6, so when the gear 6 rotates, the reinforcing rod 8 will be driven to deflect together, and when the gear 6 drives the reinforcing rod 8 to rotate 90 degrees, the driving motor 14 stops rotating at this time, and a deflection plate 9 is installed on one side surface of the reinforcing rod 8, and a suction cup 10 and a counterweight 11 are installed on the inner wall of the deflection plate 9, so when the gear 6 drives the reinforcing rod 8 to rotate, the deflection rod will be deflected due to the reinforcing rod 8. The rotation causes the angle to change. At this time, the counterweight 11 installed on the outer surface of the suction cup 10 has a certain weight. Therefore, when the reinforcing rod 8 rotates, the counterweight 11 will control the deflection plate 9 to always be in a horizontal state, so that the bottom surface of the suction cup 10 can always be at the same level with the top surface of the metal plate through rotation. When the suction cup 10 contacts the top surface of the metal plate due to the rotation of the reinforcing rod 8, the air pump starts and generates a strong suction force through the suction cup 10. At this time, the suction cup 10 will adsorb the metal plate on its bottom surface due to the suction force, thereby achieving temporary fixation.

[0035] When the adsorption is completed, the driving motor 14 is started again. When the driving motor 14 is started again, it will drive the screw 15 installed at its output end to rotate in the opposite direction, so that the ball slider 16 on the surface of the screw 15 drives the driving plate 17 to move in the opposite direction, thereby pushing the gear 6 meshing with it to rotate through the reverse movement of the driving plate 17 and the latch tooth 18. When the gear 6 rotates in the opposite direction due to the movement of the driving plate 17 and the latch tooth 18, it will drive the reinforcing rod 8 installed on one side of the surface to rotate negative 180 degrees. When the reinforcing rod 8 rotates negative 180 degrees, the suction cup 10 drives the fixed metal plate to move to another oil pressure station. When the movement is completed, the air pump stops starting at this time, so that the metal plate falls to the top surface of another station, realizing the transportation and movement of the processed metal plate after the processing is completed. When the movement is completed, the driving motor 14 is started again at this time, and the reinforcing rod 8 rotates to the initial position through the rotation of the gear 6, so as to facilitate the next stamping of the metal plate.
