[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Depend on Figures 1-4 Provided is an aluminum stamping die, comprising a base plate 1, and

[0046] A top plate 2 is provided above the bottom plate 1;

[0047] Four fixing columns 3 are fixedly connected at the four corners between the top plate 2 and the bottom plate 1;

[0048] Four first return springs 301 are respectively mounted on the lower ends of the four fixing columns 3;

[0049] The lifting plate 4 is slidably fitted on the upper end of the fixed column 3;

[0050] The upper die mechanism is provided below the lifting plate 4 and is used for stamping the aluminum material;

[0051] The lower die mechanism 6 is provided in the middle of the upper surface of the bottom plate 1 and is used to cooperate with the upper die mechanism to perform stamping and forming of the aluminum material;

[0052] The hydraulic cylinder 10 is fixedly mounted on the middle portion of the upper surface of the top plate 2 , and its output end passes through the top plate 2 and is fixedly connected to the lifting plate 4 .

[0053] By starting the hydraulic cylinder 10, the output end of the hydraulic cylinder 10 extends downward and drives the lifting plate 4 to move downward. At the same time, the lifting plate 4 can drive the upper mold mechanism to move downward and cooperate with the lower mold mechanism 6 to stamp the aluminum material, thereby stamping the aluminum material into a U-shaped shape with folded ears.

[0054] Furthermore, the bottom end of the first return spring 301 is fixedly connected to the base plate 1, and the top end of the first return spring 301 is fixedly connected to the lifting plate 4; the first return spring 301 can perform initial buffering on the upper mold mechanism, and at the same time, when the hydraulic cylinder 10 is reset, it can push the lifting plate 4 upward to reset.

[0055] Furthermore, the upper mold mechanism includes four connecting columns 5, and

[0056] A fixing plate 501 is fixedly connected to the lower surfaces of the four connecting columns 5;

[0057] The pressing block 502 is slidably fitted in the middle of the fixing plate 501;

[0058] Two forming plates 503 are symmetrically mounted on both sides of the pressing block 502;

[0059] Four guide posts 505 are fixedly connected between the lifting plate 4 and the mounting plate 504;

[0060] The mounting plate 504 is disposed above the fixing plate 501 and its lower surface is fixedly connected to the upper surface of the pressing block 502;

[0061] Four second return springs 506 are respectively sleeved on the outside of the guide column 505 , and the upper and lower ends of the second return springs 506 are respectively fixedly connected to the lifting plate 4 and the fixed plate 501 .

[0062] When the lifting plate 4 moves downward, the fixing plate 501, the pressure block 502, the forming plate 503, the mounting plate 504, the guide column 505 and the second return spring 506 can be driven downward by the connecting column 5. When the pressure block 502 contacts the aluminum material placed above the forming block 604, the lifting plate 4 and the fixing plate 501 continue to move downward under the continued driving of the hydraulic cylinder 10, so that the pressure block 502 can slide in the rectangular hole on the fixing plate 501, thereby separating the mounting plate 504 from the fixing plate 501. At the same time, the guide column 505 slides in the sliding hole on the mounting plate 504 and compresses the second return spring 506. The return spring 506 and the second return spring 506 can press the block 502 to press and position the aluminum material, and the forming plate 503 continues to move downward and punches the two ends of the aluminum material, so that the two ends of the aluminum material are folded downward and pressed against the forming block 604 under the action of the forming plate 503, thereby completing the stamping of the aluminum material; when the lifting plate 4 is reset, the fixed plate 501, the forming plate 503 and the guide column 505 are reset accordingly, and the pressure of the second return spring 506 on the mounting plate 504 gradually decreases until the mounting plate 504 contacts the fixed plate 501, and the block 502 can be reset upward accordingly.

[0063] Furthermore, the upper surfaces of the four connecting columns 5 are fixedly connected to the lower surface of the lifting plate 4, and the four connecting columns 5 are respectively located at the four corners of the upper surface of the fixed plate 501; the setting of the connecting columns 5 can enable the fixed plate 501 and the lifting plate 4 to move synchronously.

[0064] Furthermore, a rectangular hole is provided in the middle of the fixed plate 501 to match the pressing block 502, and the pressing block 502 slides in the rectangular hole. The two forming plates 503 are both L-shaped, and the horizontal end of the forming plate 503 is bolted to the bottom end of the fixed plate 501, and the bottom end of the pressing block 502 is located below the forming plate 503; in this way, the pressing block 502 can first contact the aluminum material and press the aluminum material, and the two forming plates 503, the pressing block 502 and the forming block 604 can cooperate to stamp the aluminum material into a U-shaped structure.

[0065] Furthermore, sliding holes are opened at the four corners of the mounting plate 504, and the mounting plate 504 is mounted on the guide column 505 through the sliding holes; the sliding holes and the guide column 505 cooperate to ensure the stability of the movement of the mounting plate 504, and at the same time facilitate the mounting plate 504 to compress and reset the second return spring 506.

[0066] Furthermore, the lower mold mechanism 6 includes a connecting plate 601 bolted to the bottom plate 1, and

[0067] Two L-shaped plates 602 are symmetrically bolted to the middle of the upper surface of the connecting plate 601;

[0068] baffle 603, bolted to the upper surface of the connecting plate 601 and located behind the L-shaped plate 602;

[0069] The forming block 604 is bolted to the middle of the top of the connecting plate 601 and corresponds to the pressing block 502;

[0070] The upper movable plate 605 is sleeved on the upper end of the forming block 604;

[0071] The lower movable plate 606 is sleeved on the lower end of the forming block 604;

[0072] Four cylinders 7 are fixedly connected to the four corners of the upper surface of the lower movable plate 606; the cylinders 7 can protect the third return spring 701 and support the upper movable plate 605;

[0073] Four third return springs 701 are fixedly connected to the inside of the cylinder 7, and the top ends of the third return springs 701 are fixedly connected to the bottom ends of the upper movable plate 605;

[0074] The adjustment mechanism is provided on the connecting plate 601 and located between the two L-shaped plates 602 .

[0075] When in use, the cut aluminum material can be placed on the forming block 604. At this time, the two ends and the rear end of the aluminum material are in contact with the L-shaped plates 602 and the baffle 603 on both sides respectively, so that the aluminum material can be quickly positioned and the aluminum material can be prevented from being offset during stamping. When the forming plate 503 folds the two ends of the aluminum material downward, the two ends of the aluminum material can contact the upper movable plate 605, and under the continuous downward pressure of the forming plate 503, the two ends of the aluminum material can resist the upper movable plate 605 and make the upper movable plate 605 move downward, and at the same time, the upper movable plate 605 compresses the third Reset spring 701, when the upper movable plate 605 contacts the cylinder 7, the forming plate 503, the forming block 604 and the upper movable plate 605 can form the two ends of the aluminum material into straight folding ears; when the hydraulic cylinder 10 resets and the forming plate 503 moves upward, the third reset spring 701 can rebound and reset, so that the upper movable plate 605 moves upward and drives the product to move upward, so that the product can be automatically removed and the product is easy to take out; when the size of the folding ear and the size of the U-shaped part of the product are adjusted, they can be adjusted through the adjustment structure.

[0076] Furthermore, the middle of the upper movable plate 605 and the middle of the lower movable plate 606 are provided with through holes that are compatible with the forming block 604, and the left and right ends of the upper movable plate 605 and the left and right ends of the lower movable plate 606 are respectively slidably matched with the L-shaped plate 602 on the left and the L-shaped plate 602 on the right, and the middle of both ends of the lower movable plate 606 are provided with guide holes 607; the provision of the through holes can facilitate the upper movable plate 605 and the lower movable plate 606 to move up and down on the forming block 604, and with the cooperation of the L-shaped plate 602, the upper movable plate 605 and the lower movable plate 606 can move stably.

[0077] Furthermore, a mounting groove 608 is provided at the middle of the top of the connecting plate 601 and corresponding to the guide hole 607. Two adjustment mechanisms are provided. The two adjustment mechanisms are respectively provided inside the mounting groove 608. The two adjustment mechanisms each include two symmetrically arranged threaded blocks 8, and

[0078] The bidirectional screw 9 is rotatably connected to the inside of the mounting groove 608 through a bearing. The front end of the bidirectional screw 9 passes through the connecting plate 601 and extends to the outside where it is fixedly connected to a rotating wheel 901. The rotating wheel 901 can drive the bidirectional screw 9 to rotate.

[0079] Furthermore, the bottom ends of the two threaded blocks 8 on the same side slide and fit inside the mounting groove 608, and the bottom ends of the two threaded blocks 8 are respectively threadedly connected to the two ends of the bidirectional screw 9. The upper ends of the threaded blocks 8 pass through the guide holes 607. The top ends of the two threaded blocks 8 that are away from each other are provided with a plurality of step surfaces 801, and the step surfaces 801 are in contact with the lower surface of the lower movable plate 606. When the bidirectional screw 9 is rotated forward, the bidirectional screw 9 can drive the two threaded blocks 8 thereon to approach each other, thereby making the lower movable plate 606 and the lower movable plate 606 move closer together. When the lower movable plate 606 contacts the step surface 801, the lower movable plate 606 can drive the upper movable plate 605 to move downward through the cylinder 7 and the third return spring 701, thereby reducing the contact area between the upper movable plate 605 and the two ends of the aluminum material, making the folding ear of the product smaller and the U-shaped part larger; when it is necessary to increase the size of the folding ear of the product and reduce the U-shaped part, it is only necessary to lift the lower movable plate 606 upward and rotate the bidirectional screw 9 in the opposite direction to make the two threaded blocks 8 move away from each other, so that the lower movable plate 606 contacts the step surface 801 above.
