Detailed implementation manners

[0057] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] Please refer to Figures 1-9 , and now a forging hydraulic device disclosed by the present invention will be described. The present invention is composed of eight parts, as Figure 1, including an installation foundation 1, a clamping assembly 2, a propulsion piston 3, a track 4, a placement table 5, a material picking assembly 6, a displacement block 7, and a machine frame 8. The interior of the installation foundation 1 is a hollow structure, in which the machine frame 8 is installed. A number of oil cylinders are provided at the top of the machine frame 8. The bottom of the oil cylinder penetrates through the top block of the machine frame 8, and the bottom end of the oil cylinder is connected to the displacement block 7. The displacement block 7 is drivingly connected to the four columns of the machine frame 8. The track 4 is installed on the left and right sides of the bottom block of the machine frame 8 and is placed in the hollow structure. The propulsion piston 3 is installed above the track 4. The placement table 5 is drivingly connected to the surface of the track 4 and the bottom block of the machine frame 8. The end of the propulsion piston 3 abuts against the side of the placement table 5. The material picking assemblies 6 are arranged in pairs and are installed on the left and right side surfaces of the displacement block 7. The clamping assemblies 2 are arranged in pairs and are installed on the upper surface of the bottom block of the machine frame 8. The clamping assemblies 2 are arranged on the front and rear sides of the placement table 5.

[0059] When the present invention is in use, the pushing piston 3 is utilized to push the placing table 5 to move, so that the rotating material placing platform on the placing table 5 is aligned with the magnesium alloy discharge port. The magnesium alloy that has completed the primary processing is sent to the rotating material placing platform by means of a slideway or a conveying mechanism. Then, the pushing piston 3 is used again to push the placing table 5 to translate, so that the rotating material placing platform moves below or obliquely below the material taking assembly 6. Then, the driving oil cylinder is started, and the oil cylinder will drive the displacement block 7 to move downward, so that the material taking assembly 6 moves downward and approaches the magnesium alloy. After the material taking assembly 6 moves downward, according to the shape of the magnesium alloy, the rotating member 67 can be driven to start, so that the cantilever 64 and the rotating arm 62 rotate. With the cooperation of the linkage member 63, the connecting head 642 in the cantilever 64 can be driven to move outward, and the connecting head 642 rotates. By using this characteristic, the suction magnet 65 connected to the connecting head 642 can be made to rotate, and the suction magnet 65 approaches the magnesium alloy. When the suction magnet 65 rotates, it can attract the magnesium alloy from other directions, which can ensure that the magnesium alloy is not easily detached during transportation. For special-shaped magnesium alloys, the surface that is convenient for attraction is an inclined surface. In this case, one or two of the four material discharging cylinders 643 can be utilized, and in cooperation with the ball shaft 66, the suction magnet 65 is driven to generate a flip adapted to the inclined surface, which can ensure that the contact area between the suction magnet 65 and the magnesium alloy is large and the material suction can be better. After the material suction is completed, the pushing piston 3 continues to push the placing table 5 to displace, so that the rotating material placing platform on the placing table 5 is aligned with the processing anvil on the bottom surface of the displacement block 7. Then, the rotating member 67 is driven again to make the cantilever 64 and the rotating arm 62 rotate. Using the same operation, the linkage member 63 will cause the connecting head 642 to extend and flip. By using the flipping effect of the connecting head 642, the magnesium alloy can be placed above the rotating material placing platform at an appropriate angle. Then, the oil cylinder is used to drive the displacement block 7 to move downward, so that the magnesium alloy moves downward and its surface contacts the surface of the rotating material placing platform. At this time, the four material discharging cylinders 643 are simultaneously supplied with oil, and the magnesium alloy is pushed off the suction magnet 65 by means of the material discharging cylinders 643. After being pushed off, the displacement block 7 should be quickly driven to move upward by the reset cylinder, so that the suction magnet 65 quickly moves away from the magnesium alloy to prevent re-attraction. Then, the two clamping assemblies 2 are used to simultaneously push the magnesium alloy to center and correct the magnesium alloy, and the rotation of the rotating material placing platform itself and the clamping of the clamping assemblies 2 are used to change the processing position.For the processed objects, another material taking component 6 needs to be started, and the rotating component 67 drives the cantilever 64 and the rotating arm 62 to rotate, so that the connecting head 642 is close to the processed magnesium alloy. At the same time, with the cooperation of the linkage component 63, the connecting head 642 is driven to get closer and attract the magnesium alloy at a suitable angle. For the special-shaped magnesium alloy after processing, one or two of the material return cylinders 643 are used to drive the material suction magnet 65 to deflect for attraction. After the material is attracted, the rotating component 67 drives the cantilever 64 and the rotating arm 62 to rotate in the opposite direction, and then the material return cylinder 643 is reset, and at this time the linkage component 63 is connected to the connecting head 642. The joint 642 will still flip under the drive of the linkage component 63. When it rotates to the appropriate position, the four return cylinders 643 are used to adjust the angle of the suction magnet 65 so that the end of the driving rod of the return cylinder 643 is opposite to the through hole 651 of the suction magnet 65. Then the four return cylinders 643 are used at the same time to push the magnesium alloy out to complete the discharging operation. This multi-angle discharging method can be used to discharge workpieces according to different formations. For example, for wheel-shaped workpieces, the best discharging method is to use the circular surface of its side to roll the workpiece out, which makes it easier to send the wheel-shaped workpiece to the next processing equipment.

[0060] In a specific embodiment, Figure 2 The material picking assembly 6 includes a mounting seat 61, a rotating arm 62, a linkage member 63, a cantilever 64, a material suction magnet 65, a ball shaft 66 and a rotating member 67. The mounting seat 61 is mounted on the side surface of the displacement block 7, and the rotating member 67 is installed in the mounting seat 61. One end of the rotating arm 62 is mounted on the lower part of the rotating member 67, and the cantilever 64 is mounted on the bottom of the other end of the rotating arm 62. The ball shaft 66 is mounted on the bottom of one end of the cantilever 64, and the material suction magnet 65 is installed at the bottom of the ball shaft 66. One end of the linkage member 63 is connected to the cantilever 64, and the other end of the linkage member 63 is transmission-connected to the bottom of the rotating member 67. The mounting seat 61 is used to connect the material picking assembly 6 and the displacement block 7 together, and the rotating arm 62 rotates along with the rotating shaft 674. The cantilever 64 can rotate synchronously by screwing the rotating arm 62 and the cantilever 64. The linkage member 63 is used to rotate the connecting head 642 in the cantilever 64 away from the connecting box 641 and itself when the rotating shaft 674 is driven, so that the connecting head 642 can attract the magnesium alloy from multiple angles, so that various magnesium alloy surfaces can have a larger contact area with the material suction magnet 65, which can effectively prevent the magnesium alloy from falling during transportation. The ball shaft 66 enables the material suction magnet 65 to swing at multiple angles when a certain material return cylinder 643 drives the material suction magnet 65 to flip.

[0061] In a specific embodiment, Figure 3, the mounting base 61 includes a jack 611, a mounting housing 612, a shaft cover 613, a rotary bearing 614 and a ball bearing 615. The jacks 611 are formed on the upper and lower surfaces of the mounting housing 612. The upper end of the rotating member 67 is inserted into the jack 611. The ball bearing 615 is installed in the upper jack 611, and the rotary bearing 614 is installed in the lower jack 611. The shaft cover 613 is inserted into the lower jack 611, and the shaft cover 613 abuts against the bottom of the rotary bearing 614. By using the two bearings, namely the rotary bearing 614 and the ball bearing 615, the rotating shaft 674 can not only rotate, but also rotate more stably. The jack 611 is used to install the rotary bearing 614 and the ball bearing 615, and the function of the shaft cover 613 is to prevent the rotary bearing 614 from falling off.

[0062] In a specific embodiment, such as Figure 4 , the rotating member 67 includes a washer 671, a snap ring 672, a driving gear 673, a rotating shaft 674 and a hydraulic motor 675. The bottom of the hydraulic motor 675 is inserted into the upper jack 611. The hydraulic motor 675 presses above the ball bearing 615. The top end of the rotating shaft 674 is inserted into the bottom output end of the hydraulic motor 675. The rotating shaft 674 sequentially passes through the ball bearing 615, the mounting housing 612, the ball bearing 615 and the swing arm 62. The driving gear 673 is installed at the bottom of the rotating shaft 674. The washer 671 is sleeved on the rotating shaft 674. The washer 671 is arranged below the shaft cover 613. The snap ring 672 is sleeved on the rotating shaft 674. The swing arm 62 is clamped between the snap ring 672 and the washer 671. The washer 671 and the snap ring 672 can fix the swing arm 62 on the rotating shaft 674. The hydraulic motor 675 is used to drive the rotating shaft 674 to rotate forward and backward, and the driving gear 673 is used to drive the second gear 631 and the first gear 633 to rotate.

[0063] In a specific embodiment, such as Figure 5 , the cantilever 64 includes a connecting box body 641, a connecting head 642, a blanking cylinder 643 and a connecting seat 644. The inside of the connecting box body 641 is a hollow structure, and some linkage members 63 are installed in the hollow structure. The side wall of the connecting head 642 is connected to the end of the linkage member 63. The connecting seat 644 is installed in the connecting head 642. A ball shaft 66 is installed at the bottom of the connecting seat 644. A plurality of blanking cylinders 643 are installed in the connecting head 642. The blanking cylinders 643 are arranged on the periphery of the connecting seat 644. The bottom of the driving rod of the blanking cylinder 643 is installed with an extension rod. The connecting box body 641 is used to install some linkage members 63, and the connecting head 642 is used to install the blanking cylinder 643 and the connecting seat 644.

[0064] In a specific embodiment, such as Figure 6The linkage component 63 includes a second gear 631, a second rotating rod 632, a first gear 633, a first rotating rod 634, a return spring 635, a driving sleeve 636 and a connecting rod 637. One end of the first rotating rod 634 is installed in the connecting box 641, and the other end of the first rotating rod 634 is installed with the first gear 633. The driving sleeve 636 is screwed and installed at one end of the first rotating rod 634. The driving sleeve 636 is transmission-connected in the connecting box 641. The second rotating rod 632 is inserted in the first rotating rod 634, and one end of the second rotating rod 632 is connected to the second gear 631. The other end of the second rotating rod 632 is provided with a through hole, and a connecting rod 637 is transmission-connected in the through hole. One end of the connecting rod 637 is connected to the side wall of the connecting head 642, and the return spring 635 is installed between the through hole and the other end of the connecting rod 637. When the active gear 673 drives the second gear 631 to rotate, the second rotating rod 632 rotates. During the rotation of the second rotating rod 632, due to the design of the limit groove 6312 and the block 6310, the connecting rod 637 can only translate along the second rotating rod 632. In this way, during the rotation of the second rotating rod 632, the connecting rod 637 can only rotate with the second rotating rod 632. Since one end of the connecting rod 637 is connected to the connecting head 642, the connecting head 642 will also rotate with it. In this way, the connecting head 642 will rotate with the suction magnet 65 to perform multi-angle suction of the magnesium alloy. When the active gear 673 drives the first gear 633 to rotate, the first rotating rod 634 will rotate synchronously, and the connecting head 642 will rotate with the suction magnet 65 to perform multi-angle suction of the magnesium alloy. Figure 6 63 and 64. The threaded structure shown in the figure cooperates with the rectangular hole on the side of the connecting box 641 and the guide bar 6311 on the sleeve 636, so that when the first rotating rod 634 rotates, the sleeve 636 will use the threaded structure to generate translation. During the translation, the sleeve 636 will gradually approach and push the connecting head 642 to move, so that the connecting head 642 is away from the connecting box 641 and gradually approaches the magnesium alloy, so that the material can be better taken during the material taking process. When resetting after the material taking is completed, the driving gear 673 will produce reverse rotation. At this time, the first rotating rod 634 rotates in the opposite direction to reset the sleeve 636. When the sleeve 636 drives the connecting head 642 to move, the connecting rod 637 will extend from the second rotating rod 632, and the reset spring 635 will generate tensile deformation to generate elastic force. This elastic force will take effect when the sleeve 636 leaves the connecting head 642, pulling the connecting rod 637 back into the second rotating rod 632, so that the connecting head 642 is close to the connecting box 641 again, which is convenient for the next material taking operation.

[0065] In a specific embodiment, Figure 7, a limiting ring 638 is installed on the side wall of the first rotating rod 634. The limiting rings 638 are arranged in pairs and are disposed at both ends of the side wall of the connecting box body 641. Guide bars 6311 are installed on the upper and lower surfaces of the driving sleeve 636. A snap ring 639 is arranged inside the first rotating rod 634. The inside of the snap ring 639 abuts against the outer surface of the second rotating rod 632. Limiting grooves 6312 are opened at the upper and lower ends of the through hole. Clamping blocks 6310 are installed on the upper and lower sides of one end of the connecting rod 637. The clamping blocks 6310 are drivingly connected in the limiting grooves 6312. A top block is arranged at the end of the second rotating rod 632. The limiting ring 638 is used to prevent the first rotating rod 634 from translating along the connecting box body 641, while the snap ring 639 is used to ensure the stability of the second rotating rod 632 during rotation.

[0066] In a specific embodiment, such as Figure 8 , the material suction magnet 65 includes a through hole 651, a hemispherical hole 652, a plate body 653 and an elastic retaining piece 654. The plate body 653 is installed at the bottom of the ball shaft 66. A number of hemispherical holes 652 are opened on the surface of the plate body 653. A number of through holes 651 are opened on the plate body 653. The through holes 651 are arranged below the hemispherical holes 652 and are communicated with the hemispherical holes 652. An elastic retaining piece 654 is installed at the bottom of the hemispherical hole 652. By using the hemispherical holes 652 and the elastic retaining piece 654 on the material suction magnet 65, when the material suction magnet 65 deflects, the material discharging cylinder 643 can only drive the material suction magnet 65 to deflect, and the driving rod of the material discharging cylinder 643 is not allowed to extend into the through hole 651. After the material suction magnet 65 deflects and finishes suctioning, each material discharging cylinder 643 needs to be used in cooperation. The extended driving rod slightly adjusts the material suction magnet 65 so that the material suction magnet 65 finally faces the bottom surface of the connector 642. In this way, during discharging, the four material discharging cylinders 643 can be operated synchronously, the four driving rods are simultaneously extended into the through hole 651, and continue to move to push out the magnesium alloy connected by the material suction magnet 65 to complete discharging. The elastic retaining piece 654 is made of a flexible material. When only one or two material discharging cylinders 643 are used, the thrust of the driving rod is not enough to drive the elastic retaining piece 654 to flip, so that the driving rod cannot enter the through hole 651. When the four material discharging cylinders 643 act simultaneously, the thrust of their driving rods can drive the elastic retaining piece 654 to deflect, so that the driving rod enters the through hole 651.

[0067] In a specific embodiment, such as Figure 9, the propulsion piston 3 includes a push block 31, a connecting block 32, a driving cylinder 33 and a transmission rod 34. The connecting blocks 32 are arranged in pairs and installed on the surface of the track 4. A driving cylinder 33 is installed between the two connecting blocks 32. The transmission rod 34 is drivingly connected in the driving cylinder 33. A push block 31 is installed at the end of the transmission rod 34, and the push block 31 abuts against the side wall of the placement table 5. By allowing hydraulic oil to enter the driving cylinder 33, the transmission rod 34 is displaced, so that the push block 31 contacts the placement table 5 and the placement table 5 moves.

[0068] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
