Description

Technical Field

[0001] This invention relates to the field of metal stamping technology, and more particularly to a stamping forming apparatus for metal manufacturing. Background Technology

[0002] Aluminum alloy gas cylinders, with their advantages of being lightweight, clean, and corrosion-resistant, are widely used as a replacement for steel cylinders in fields such as vehicle-mounted CNG / LNG / H2, medical oxygen, laser gas, and household CO2. In aerospace, 2195 aluminum-lithium alloy is used to make liquid oxygen, liquid hydrogen, and helium storage tanks, which do not lose strength at low temperatures and have a fatigue life of up to 100,000 cycles, helping rockets and satellites achieve gram-level weight reduction and long-life operation. In the production process of aluminum alloy gas cylinders, pressure is applied to the aluminum alloy sheet through a stamping forming device to deform it, thereby processing the aluminum alloy sheet into the required shape and specifications, obtaining the required bottom cover shape, and ensuring the sealing, durability, and aesthetics of the aluminum alloy gas cylinder.

[0003] In existing aluminum alloy gas tank bottom stamping lines, after the tank bottom is formed, the lower die ejection mechanism throws it to the side of the mold. Workers then have to manually pick up the still-hot aluminum alloy tank bottom pieces one by one, stack them neatly, and move them to the material rack. This method has particularly prominent drawbacks in multi-station high-speed stamping scenarios. It requires workers to frequently reach into the machine tool's danger zone, posing significant safety hazards. Moreover, the actions of picking up parts, turning around, and stacking are not matched with the machine's cycle time, resulting in long single-piece unloading times, which becomes a bottleneck for the entire production line. Furthermore, high-temperature aluminum parts are prone to sticking to gloves, and uneven stacking can lead to subsequent bumps and scratches, reducing the yield rate.

However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] In practical use, it was found that in existing aluminum alloy gas tank bottom stamping lines, after the tank bottom is formed, the lower die ejection mechanism throws it to the side of the mold. Workers need to manually pick up the still-hot aluminum alloy tank bottom pieces one by one, stack them neatly, and move them to the material rack. This method has particularly prominent drawbacks in multi-station high-speed stamping scenarios. It requires workers to frequently reach into the dangerous area of ​​the machine tool, posing a significant safety hazard. Moreover, the actions of picking up parts, turning around, and stacking are not matched with the machine's cycle time, resulting in long single-piece unloading time, which becomes a bottleneck for the entire production line.

The moving mechanism includes a moving motor 12. A vertical groove is opened through the rear side of the feeding frame 5. A screw 13 is rotatably connected to the inner side of the vertical groove. A commutator 14 is fixedly connected through the bottom of the feeding frame 5. The bottom end of the screw 13 passes through the outer wall of the feeding frame 5 and is fixedly connected to one of the output ends of the commutator 14. The moving motor 12 is fixedly connected to the rear side of the commutator 14, and the output end of the moving motor 12 is fixedly connected to the other output end of the commutator 14.

The lifting frame 8 is slidably connected to the inner side of the vertical groove. The screw 13 is threadedly connected to the inner side wall of the lifting frame 8. A fixed tank bottom 15 is fixedly connected to the top of the lifting frame 8. The stacking mechanism includes a lower electric telescopic cylinder 16. Side slots are provided through both sides of the outer wall of the feeding frame 5. A pair of lower electric telescopic cylinders 16 are provided. The lower electric telescopic cylinders 16 are fixedly connected to the inside of the side slots. The output end of the lower electric telescopic cylinder 16 is fixedly connected to the bottom of the fixed frame 9. Three side frames 17 are provided inside the fixed frame 9. The top of the three side frames 17 is flush with the top of the middle stamping die 2, the upper stamping die 3 and the lower stamping die 4 respectively. A front slot is provided through the front side of the fixed frame 9. A round rod 18 is slidably connected through the front side of the side frame 17 relative to the front slot. A U-shaped frame 19 is slidably connected laterally to the bottom of the side frame 17. The rear side of the round rod 18 is fixedly connected to the front side of the U-shaped frame 19. An adjustment slot 20 is provided inside the U-shaped frame 19. The front side of the adjustment slot 20 is inclined. A T-shaped plate 21 is slidably connected through the middle of the side wall of the side frame 17. A side plate 22 is fixedly connected to the side wall of the T-shaped plate 21. The side plate 22 away from the T-shaped plate 21 is set with a smooth arc surface, which is convenient to be squeezed more smoothly by the inclined surface of the adjustment groove 20 and push the side plate 22 to slide. Two pairs of upper springs 23 are fixedly connected between the side wall of the T-shaped plate 21 and the inner side of the side frame 17. The side wall of the side plate 22 is in contact with the inner side of the U-shaped frame 19. A return spring 24 is fixedly connected between the inner side of the side frame 17 and the rear side of the U-shaped frame 19. The front side of the round rod 18 is set with a smooth arc surface. An adjustment frame 25 is fixedly connected to the front end of the feeding frame 5 relative to the front position of the side groove. The round rod 18 is inserted into the inner side of the adjustment frame 25. A groove 26 is provided on the inner side wall of the adjustment frame 25, and the connection between the groove 26 and the inner side of the adjustment frame 25 is inclined. The material pushing mechanism includes a pair of side electric telescopic cylinders 27. Each of the two side electric telescopic cylinders 27 is fixedly connected to the top of the fixed platform 6. Each of the L-shaped plates 28 has a storage groove on its inner side. Each of the storage grooves has a push plate 29. Each of the side electric telescopic cylinders 27 is fixedly connected to the side wall of the L-shaped plate 28. The output end of each of the side electric telescopic cylinders 27 passes through the inner side of the storage groove and is fixedly connected to the side wall of the push plate 29. Each of the two fixed platforms 6 has a front frame 30 fixedly connected to the front side. Each of the two fixed platforms 6 has a sliding groove in the middle of its top. The side wall of the sliding groove is connected to the inner side of the front frame 30. A sliding frame 31 is slidably connected to the inner side of the front frame 30. The bottom end of the push plate 29 is fixedly connected to the top end of the sliding frame 31. A support plate 32 is slidably connected to the rear side of the front frame 30 relative to the front of the unloading frame 5. The top of the support plate 32 has a through groove 33, and the side wall of the groove 33 has a horizontal groove 35. The top of the sliding frame 31 is fixedly connected to a guide rod 36, which is inserted into the inside of the groove 33. The rear side of the top of the fixed platform 6 is fixedly connected to a side block 37, which is located near the unloading frame 5. The side block 37 is inclined on the side close to the L-shaped plate 28. The inclined surface can play a squeezing and positioning role for the pushed aluminum alloy can bottom. When the pushed aluminum alloy can bottom deviates, the side wall of the aluminum alloy can bottom will be squeezed on the side block 37 or the inclined surface of the L-shaped plate 28. As the unloading plate 11 continues to push, the aluminum alloy can bottom will be accurately pushed into the inside of the L-shaped plate 28 under the squeezing action of the inclined surface, thus ensuring accurate stacking in the future. When stamping the bottom of the aluminum alloy gas tank, first place three aluminum alloy plates on the middle stamping die 2, the upper stamping die 3, and the lower stamping die 4. Then, control the stamping machine 1 to start and extrude the aluminum alloy sheet metal. After stamping, the formed aluminum alloy tank bottom is ejected. Then, control the upper electric telescopic cylinder 10 to start and drive the unloading plate 11 to move forward, thereby pushing the aluminum alloy tank bottom forward. This pushes the aluminum alloy tank bottom on the middle stamping die 2 onto the two lowest T-shaped plates 21 on the unloading frame 5. At the same time, push the aluminum alloy tank bottoms on both sides onto the corresponding fixed platforms 6. Then, control the side electric telescopic cylinder 27 to start and drive the push plate 29 to move towards the middle, thereby pushing the aluminum alloy tank bottom through the fixed frame 9 to move onto the other two T-shaped plates 21. During this process, the movement of the push plate 29 will drive the sliding frame 31 to move, which in turn will drive the guide rod 36 to move. Since the support plate 32 can only slide horizontally back and forth, under the action of the lateral movement of the guide rod 36, the guide rod 36 will squeeze the inclined surface of the inclined groove 33, causing the support plate 32 to move to the rear side, thereby extending the support plate 32. Then the guide rod 36 moves out of the inclined groove 33 and moves into the horizontal groove 35. At this time, the support plate 32 is fully extended. Then the push plate 29 pushes the aluminum alloy can bottom out of the fixed frame 9 and moves it onto the support plate 32, thereby providing support for the aluminum alloy can bottom between the fixed frames 9, ensuring that the aluminum alloy can bottom will not fall off during the pushing process. At this time, the guide rod 36 will continue to slide in the horizontal groove 35. When the push plate 29 moves to the side frame 17, since the sliding frame 31 is fixed at the bottom of the push plate 29 away from the side frame 17, the push plate 29 can move to the side frame 17 without affecting the complete pushing of the aluminum alloy can bottom into the T-shaped plate 21. After the aluminum alloy can bottoms on both sides are pushed in, the side electric telescopic cylinder 27 can be controlled to reset, and the guide rod 36 can be driven to reset. The above operation is repeated to pull the support plate 32 to reset. Finally, the lower electric telescopic cylinder 16 can be controlled to start and drive the fixed frame 9 to slide downward, while simultaneously driving the side frame 17 and the aluminum alloy can bottom to move downward. At this time, the round rod 18 will slide within the adjusting frame 25 (at this time, the round rod 18 and the reset spring 24 are in a compressed state). Then, when the bottom aluminum alloy can bottom is about to be completely inserted into the fixed can bottom 15, the bottom side frame 17 will... The upper round rod 18 moves above the groove 26, thereby gradually releasing the pressure on the round rod 18. At this time, under the elastic force of the return spring 24, the round rod 18 will slide forward along the slope of the groove 26, and drive the U-shaped frame 19 forward, thereby moving the adjustment groove 20 to the side plate 22, releasing the pressure on the side plate 22. Then, under the elastic force of the upper spring 23, the T-shaped plate 21 is pushed to slide to both sides, thereby moving the T-shaped plate 21 out from under the bottom of the aluminum alloy can, releasing the restriction on the bottom of the aluminum alloy can, and then the bottom of the aluminum alloy can falls onto the fixed can bottom 15 under its own weight. Then, as the fixed frame 9 continues to move downward, the round rod 18 on the second side frame 17 moves above the groove 26, causing the second aluminum alloy can bottom to overlap the first aluminum alloy can bottom. This repeats the above operation, stacking the two aluminum alloy can bottoms on the lifting frame 8. Finally, the third side frame 17 moves above the groove 26, repeating the above operation to stack the three aluminum alloy can bottoms together. This controls the start of the moving motor 12, which, driven by the commutator 14, drives the screw 13 to rotate. This, in turn, causes the threaded lifting frame 8 and the fixed can bottom 15 to move downward, thus causing the three can bottoms to stack together. The bottom of the aluminum alloy can moves downward a certain distance (it should be noted that the downward movement distance is fixed each time, which not only ensures that the corresponding aluminum alloy can bottom will not move upward when the T-shaped plate 21 is reset, but also ensures the normal stacking of the subsequent aluminum alloy can bottoms). At this time, the lower electric telescopic cylinder 16 can be started to repeat the above operation in reverse. Under the pressure of the inclined surface of the groove 26, multiple round rods 18 slide backward and compress the reset spring 24. At the same time, the inclined surface of the adjustment groove 20 presses the side plate 22, causing the T-shaped plate 21 to extend and compress the upper spring 23. Then the reset is completed, and the above operation can be repeated for unloading.

[0023] In summary, the above-described structure automatically pushes the three stamped aluminum alloy can bottoms onto the fixed platform 6. Then, under the operation of the pushing mechanism, the three aluminum alloy can bottoms are pushed together onto the T-shaped plate 21. Subsequently, under the operation of the stacking mechanism, the three aluminum alloy can bottoms are stacked sequentially on the fixed can bottom 15, thereby realizing the automatic stacking and unloading of the three can bottoms without the need for workers to pick up and stack them, greatly improving the convenience of the device.

[0024] Based on the above embodiments, it was found during use that although the above structure can realize automatic unloading after the stamping of three aluminum alloy can bottoms, the spacing between the side frames 17 is fixed. Therefore, it can only stack and unload aluminum alloy can bottoms of different sizes, which is relatively limited and cannot meet the diverse production needs. In order to solve the above problems, the above structure has been further improved.

[0025] A pair of movable slots are provided through the front side of the fixed frame 9. Movable plates 38 inserted into the movable slots are fixedly connected to both the front and rear sides of the side frame 17. Several through holes are provided at equal intervals on the side wall of the fixed frame 9. A pair of bolts 34 are provided on the side wall of the side frame 17. The side ends of the bolts 34 are threaded through the through holes and connected to the inside of one of the movable plates 38. When adjusting the aluminum alloy can bottoms of different heights, first replace the corresponding middle stamping die 2, upper stamping die 3, and lower stamping die 4 (it should be noted that the distance between the dies after replacement must also be greater than the height of the aluminum alloy can bottom, and the top of the middle stamping die 2 must always be flush with the top of the bottom T-shaped plate 21). Then adjust the height of the blanking plate 11 to ensure its normal operation. Next, adjust the height of the fixed platform 6 through the liftable bracket 7 to ensure that the height of the fixed platform 6 is flush with the top of the upper stamping die 3 and the lower stamping die 4. Then, rotate the bolt 34 to release the restriction on the side frame 17, and push the side frame 17 to make the moving plate 38 slide in the moving groove. Adjust the top of the side frame 17 to be flush with the top of the fixed platform 6, and then screw in the bolt 34 to fix the position of the side frame 17. The adjustment is then complete.

[0026] In summary, the above structural design allows for flexible adjustment of the spacing between the three side frames 17 according to the height of the aluminum alloy can bottom when producing aluminum alloy can bottoms of different heights. This makes it suitable for stamping production of aluminum alloy can bottoms of different sizes, improving the versatility and applicability of the device.
