A ventilation hose 406 is fixedly connected to the top of the check valve two 405, and the ventilation hose 406 plays a connecting role. An air storage tank 407 is fixedly connected to the inside of the base 1, and the air storage tank 407 can store gas. The up and down movement of the movable cylinder 403 in cooperation with the fixed plug 402 can fill the inside of the air storage tank 407 with gas. The bottom end of the ventilation hose 406 is fixedly connected to the outside of the air storage tank 407.

The inside of the movable cylinder 403 is slidably connected to the outside of the fixed plug 402. When storing air pressure, the extension and retraction of the output end of the hydraulic cylinder 3 can drive the mold changing mechanism 6 to move up and down, thereby driving the movable cylinder 403 to move up and down. When the movable cylinder 403 moves upward, the check valve one 404 opens and the check valve two 405 closes, so that air can be drawn into the inside of the movable cylinder 403 from the outside through the check valve one 404. When the movable cylinder 403 moves downward, the check valve one 404 closes and the check valve two 405 opens. At this time, the air inside the movable cylinder 403 will enter the inside of the air storage tank 407 through the ventilation hose 406, and the air storage tank 407 is used to store gas.

[0033] The quick demolding mechanism 5 includes two fixed cylinders 501 which provide installation positions. The tops of the two fixed cylinders 501 are respectively fixedly connected to both ends of the top of the mounting frame 2. A piston 502 is slidably connected inside the fixed cylinder 501.

Slide rings 512 are slidably connected to both outer sides of the mounting frame 2. Push springs 511 are sleeved on both outer sides of the mounting frame 2. One end of the push spring 511 is fixedly connected to the bottom of the bottom pad 510, and the other end of the push spring 511 is fixedly connected to the bottom of the slide ring 512. The clamping plate 509 is engaged with the top of the mounting groove plate 507. One end of the connector 504 away from the fixed cylinder 501 is fixedly connected to the top of the connecting pipe 408. When demolding, the automatic valve on the connecting pipe 408 is opened. At this time, the gas inside the air storage tank 407 will enter the inside of the connector 504 through the connecting pipe 408, and then enter the inside of the fixed cylinder 501 through the connector 504. Thus, the piston 502 can be pushed downward by the air pressure, and then the moving column 503 can be driven to move downward by the piston 502. The connecting plate 506 is driven to move downward by the moving column 503, and then the clamping plate 509 and the lower mold 508 can be driven to move downward so that the bottom of the lower mold 508 is attached to the top of the backing plate 8. At this time, the hydraulic cylinder 3 is started and the output end of the hydraulic cylinder 3 extends, and then the mold changing mechanism 6 can be driven to move downward for the treatment of aluminum materials. When the aluminum materials are processed, the output end of the hydraulic cylinder 3 is retracted, and then the mold changing mechanism 6 is driven to move upward. At this time, the exhaust valve 505 is opened, and the air inside the fixed cylinder 501 will be discharged through the exhaust valve 505. At this time, under the reaction force of the push spring 511, the connecting plate 506 is driven to move upward, so that the mounting groove plate 507 can be driven to move upward. After the mounting groove plate 507 moves upward, the clamping plate 509 is driven to move upward. After the clamping plate 509 moves upward, the lower mold 508 is driven to move upward, and then the processed aluminum materials inside the lower mold 508 can fall out of the inside of the lower mold 508 under the action of gravity, and then it is convenient to take out the finished products.

[0034] The mold replacement mechanism 6 includes a mounting column 601, which provides a mounting position. The top of the mounting column 601 is fixedly connected to the output end of the hydraulic cylinder 3. The external top of the mounting column 601 is fixedly connected to a top plate 602. The external sleeve of the mounting column 601 is provided with a reset spring 603. The external sliding connection of the mounting column 601 is connected to a movable cover 604. The reset spring 603 can drive the movable cover 604 to reset. The bottom of the mounting column 601 is clamped with a clamping block 605, and the clamping block 605 can be engaged with the mounting column 601. The bottom of the clamping block 605 is fixedly connected to a bottom column 606. The bottom of the bottom column 606 provides a mounting position. The bottom of the bottom column 606 is fixedly connected to an upper mold 607. The outside of the bottom column 606 is detachably connected to a connecting mounting plate 608. The movable column 503 is The outer bottom end is rotatably connected with a rotating hollow seat 609, and the rotating hollow seat 609 provides an installation position. A torsion spring 610 is arranged inside the rotating hollow seat 609. The outer part of the rotating hollow seat 609 is fixedly connected with a blocking block 611. The torsion spring 610 can drive the rotating hollow seat 609 to reset. The outer part of the fixed cylinder 501 is fixedly connected with a rotating blocking handle 613, and the outer part of the blocking block 611 is fixedly connected with a toggle handle 612. The toggle handle 612 is convenient for driving the blocking block 611 to rotate. The end of the connecting mounting plate 608 away from the bottom column 606 is fixedly connected to the outside of the movable cylinder 403, one end of the torsion spring 610 is fixedly connected to the inside of the rotating hollow seat 609, and the other end of the torsion spring 610 is fixedly connected to the bottom of the movable column 503, so as to replace the upper mold 607 When the upper mold 607 is installed, it is only necessary to engage the block 605 with the bottom of the mounting post 601 and rotate the rotation blocking handle 613 away from the bottom of the movable cover 604. At this time, the movable cover 604 can be driven to move downward under the action of the reset spring 603, so that the movable cover 604 can be made to move downward. The movable cover 604 moves to the outside of the clamping block 605 again, and then the upper mold 607 can be installed. When replacing the lower mold 508, first turn the toggle handle 612, and the toggle handle 612 drives the blocking block 611 to rotate. When the blocking block 611 leaves the range of the clamping plate 509, the lower mold 508 can be taken out from the inside of the installation slot plate 507. When installing the lower mold 508, first put the lower mold 508 into the inside of the installation slot plate 507, and make the clamping plate 509 engage with the top of the installation slot plate 507. At this time, release the toggle handle 612, and drive the rotating hollow seat 609 to rotate in the opposite direction under the action of the torsion spring 610, so that the rotating hollow seat 609 can be driven to rotate and reset, and then the blocking block 611 can be driven to rotate and reset.Thus, the blocking block 611 can be rotated to the top of the clamping plate 509, completing the installation of the lower die 508.

[0035] The pressure relief mechanism 7 includes a bottom ring 701 which provides an installation position. One end of the bottom ring 701 is fixedly connected to the outside of the gas storage tank 407. The other end of the bottom ring 701 is fixedly connected with an outer tube 702 which provides an installation position. A hollow inner column 703 is slidably connected inside the outer tube 702. An exhaust hole 704 is opened at one end of the hollow inner column 703 away from the bottom ring 701. A plurality of air inlet holes 706 are opened at one end of the hollow inner column 703 close to the exhaust hole 704. The cooperation of the air inlet holes 706 and the exhaust hole 704 can facilitate the discharge of the gas inside the gas storage tank 407. A fixing ring 705 is fixedly connected to the outside of the hollow inner column 703. A plurality of plug rods 707 are fixedly connected to the inner side of the bottom ring 701. The outside of the plug rods 707 is slidably connected inside the air inlet holes 706. A tension spring 708 is sleeved outside the outer tube 702. One end of the tension spring 708 is fixedly connected to one end of the bottom ring 701 close to the fixing ring 705, and the other end of the tension spring 708 is fixedly connected to one end of the fixing ring 705 close to the bottom ring 701. When the air pressure inside the gas storage tank 407 is too high, the gas will push the hollow inner column 703 to move outwards to the outside of the outer tube 702. When the outer tube 702 moves out of the range of the plug rods 707, due to the blockage of the plug rods 707 inside the outer tube 702, the gas inside the gas storage tank 407 can then enter the inside of the hollow inner column 703 through the air inlet holes 706, and the gas inside the hollow inner column 703 is discharged through the exhaust hole 704. Thus, the gas inside the gas storage tank 407 is discharged through the exhaust hole 704, and the gas pressure inside the gas storage tank 407 can be prevented from being too high.

[0036] The working principle of a stamping and stretching device for aluminum material processing according to the present invention: When storing air pressure, the extension and retraction of the output end of the hydraulic cylinder 3 can drive the die changing mechanism 6 to move up and down, thereby driving the movable cylinder 403 to move up and down. When the movable cylinder 403 moves upwards, the one-way valve 404 opens and the one-way valve 405 closes. Thus, air can be drawn from the outside into the inside of the movable cylinder 403 through the one-way valve 404. When the movable cylinder 403 moves downwards, the one-way valve 404 closes and the one-way valve 405 opens. At this time, the air inside the movable cylinder 403 will enter the inside of the gas storage tank 407 through the ventilation hose 406, and the gas storage tank 407 is used to store the gas.

[0037] When demoulding, the automatic valve on the connecting pipe 408 is opened. At this time, the gas inside the air storage tank 407 will enter the inside of the connector 504 through the connecting pipe 408, and then enter the inside of the fixed cylinder 501 through the connector 504. Thus, the piston 502 can be pushed to move downward by the air pressure. Subsequently, the moving column 503 can be driven to move downward by the piston 502. The connecting plate 506 is driven to move downward by the moving column 503. Then, the clamping plate 509 and the lower mold 508 can be driven to move downward, and the bottom of the lower mold 508 is made to abut against the top of the backing plate 8. At this time, the hydraulic cylinder 3 is activated, and the output end of the hydraulic cylinder 3 extends. Then, the mold changing mechanism 6 can be driven to move downward to process the aluminum material. After the aluminum material is processed, the output end of the hydraulic cylinder 3 is retracted, and then the mold changing mechanism 6 is driven to move upward. At this time, the exhaust valve 505 is opened, and the air inside the fixed cylinder 501 will be discharged through the exhaust valve 505. At this time, under the reaction force of the pushing spring 511, the connecting plate 506 is driven to move upward, so that the mounting groove plate 507 can be driven to move upward. After the mounting groove plate 507 moves upward, the clamping plate 509 is driven to move upward. After the clamping plate 509 moves upward, the lower mold 508 is driven to move upward. Then, the processed aluminum material inside the lower mold 508 can fall out of the lower mold 508 under the action of gravity, facilitating the taking out of the finished product.

[0038] When replacing the upper die 607, first rotate the rotating blocking handle 613 under the movable cover 604. At this time, start the hydraulic cylinder 3. After the hydraulic cylinder 3 starts, it can drive the mounting column 601 to move downward. At this time, use the top plate 602 to compress the return spring 603. And at this time, the movable cover 604 moves to the top of the block 605. At this time, the block 605 can be moved out from the bottom of the mounting column 601. At this time, the bottom column 606 and the upper die 607 are disassembled from the bottom of the mounting column 601. When installing the upper die 607, just engage the block 605 with the bottom of the mounting column 601 and rotate the rotating blocking handle 613 away from under the movable cover 604. At this time, under the action of the return spring 603, it can drive the movable cover 604 to move downward, so that the movable cover 604 can move back outside the block 605, and then the installation of the upper die 607 can be realized. When replacing the lower die 508, first rotate the toggle handle 612. The toggle handle 612 drives the blocking block 611 to rotate. When the blocking block 611 leaves the range of the clamping plate 509, the lower die 508 can be taken out from the inside of the mounting groove plate 507. When installing the lower die 508, first place the lower die 508 into the inside of the mounting groove plate 507 and make the clamping plate 509 engage with the top of the mounting groove plate 507. At this time, release the toggle handle 612. Under the action of the torsion spring 610, it drives the rotating hollow seat 609 to rotate in the reverse direction, so that the rotating hollow seat 609 can rotate back to its original position, and then drive the blocking block 611 to rotate back to its original position, so that the blocking block 611 can rotate to the top of the clamping plate 509, and the installation of the lower die 508 is completed;

[0039] When the air pressure inside the gas storage tank 407 is too high, the gas will push the hollow inner column 703 to move outward to the outside of the outer tube 702. When the outer tube 702 moves out of the range of the plug rod 707, due to the blockage of the plug rod 707 inside the outer tube 702, then the gas inside the gas storage tank 407 can enter the inside of the hollow inner column 703 from the air inlet hole 706, and the gas inside the hollow inner column 703 is discharged through the exhaust hole 704, so that the gas inside the gas storage tank 407 is discharged through the exhaust hole 704, and then the gas pressure inside the gas storage tank 407 can be prevented from being too high.
