[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A tooling for extruding aluminum sheet, such as Figures 1-5 As shown, the tooling includes a support frame 1, a support plate 2 fixedly connected to the support frame 1, several cylinders 3 fixedly connected to the support plate 2, and a pressure plate 4 fixedly connected to the output end of the cylinders 3. The support frame 1 is equipped with a receiving assembly for receiving aluminum blanks and a grinding assembly for grinding aluminum plates. The receiving assembly includes an electric slide rail 5 fixedly connected to the bottom side of the support frame 1, a slider 6 slidably connected to the electric slide rail 5, a spring telescopic rod 7 fixedly connected to the slider 6, and a receiving plate 8 detachably connected to several spring telescopic rods 7. The receiving plate 8 is located on the upper side of the support frame 1. When needed, the electric slide rail 5 can be activated to drive the slider 6 to move, so that the slider 6 and the spring telescopic rod 7 are not under the pressure plate 4. Then, the original receiving plate 8 can be manually lifted and replaced with a receiving plate 8 of different specifications, thereby improving the applicability of the tooling.

[0022] like Figures 1-5As shown, before use, the electric slide rail 5 is activated, which drives the slider 6 to move, so that the slider 6 and the spring telescopic rod 7 are not under the pressure plate 4. Then, the receiving plate 8 is installed on the spring telescopic rod 7. Next, the electric push rod 9 is activated, so that the receiving plate 8 is under the pressure plate 4. At this time, the receiving plate 8 is lifted by the spring telescopic rod 7 and does not contact the inner bottom side of the support frame 1. Then, the heated aluminum billet is placed on the receiving plate 8. Then, several cylinders 3 are activated to extend and drive the pressure plate 4 to approach the aluminum billet and squeeze the aluminum billet. At this time, the receiving plate 8 and the support frame 1 cooperate to form a closed groove. Then, the aluminum billet will be squeezed into shape in the groove. During the extrusion process, the receiving plate 8 will contact the inner bottom side of the support plate 2. At this time, the spring telescopic rod 7 is in a deformed state. Then, cylinder 3 will continue to extend and extrude the aluminum blank until the final aluminum plate is level with the receiving plate 8. After extrusion, several cylinders 3 can be activated to retract, moving the pressure plate 4 away from the aluminum plate. At this time, the receiving plate 8 is no longer pushed by the pressure plate 4, and the spring telescopic rod 7 will reset, slightly lifting the receiving plate 8 so that the bottom side of the receiving plate 8 is no longer in contact with the support frame 1, thus making the receiving plate 8 slide more smoothly. During this process, the grinding component will be triggered, and then the electric slide rail 5 will be activated. The electric slide rail 5 will move the slider 6, the spring telescopic rod 7, and the receiving plate 8 away from the underside of the pressure plate 4. When the receiving plate 8 passes through the slot of the support frame 1 and is no longer under the pressure plate 4, the aluminum plate can be removed simply by pushing the aluminum plate and then removing it.

[0023] like Figure 1 , Figure 4 As shown, an electric push rod 9 is fixedly connected to the support frame 1. A pushing plate 10 is fixedly connected to the telescopic end of the electric push rod 9. When the receiving plate 8 passes through the through slot of the support frame 1 and is no longer under the pressure plate 4, the electric push rod 9 can be activated to extend. Then the electric push rod 9 will drive the pushing plate 10 to contact the aluminum plate and make the aluminum plate slide on the receiving plate 8, so that the aluminum plate and the receiving plate 8 are misaligned. In this way, the aluminum plate does not need to be pushed manually, making it easier to remove the aluminum plate.

[0024] like Figure 1 , Figure 2 As shown, the grinding assembly includes a second spring telescopic rod 11 fixedly connected to the support frame 1, a positioning plate 12 fixedly connected to the second spring telescopic rod 11, several third spring telescopic rods 13 fixedly connected to the positioning plate 12, and a grinding block 14 fixedly connected to the telescopic ends of several third spring telescopic rods 13. The positioning plate 12 is provided with a driving component for driving the positioning plate 12 to slide. The driving component includes a positioning frame 15 fixedly connected to the support frame 1 and a baffle 16 rotatably connected to the positioning frame 15. The baffle 16 is in contact with the positioning plate 12.

[0025] like Figure 1 , Figure 2As shown, when the pressure plate 4 completes the extrusion molding and moves upward due to the contraction of the cylinder 3, the upper side of the pressure plate 4 will contact the baffle 16. Then, the electric slide rail 5 is activated, causing the receiving plate 8 to pass through the through slot of the support frame 1. During the passage process, the cylinder 3 continues to contract, and the baffle 16 will be pushed by the pressure plate 4 and rotate to push the positioning plate 12. At this time, the second spring telescopic rod 11 is deformed into a contracted state, and the first grinding block 14 will contact the top side of the aluminum plate. At this time, the third spring telescopic rod 13 will also contract and deform, so that the first grinding block 14 is always in contact with the aluminum plate. At this point, the electric slide rail 5 is activated to move the aluminum plate away from the lower side of the pressure plate 4, which allows for grinding and polishing of the top side of the aluminum plate, thereby improving the extrusion molding effect. After grinding, the cylinder 3 is activated to extend, and the top plate will no longer push the positioning plate 12. The spring telescopic rod 11 and the spring telescopic rod 13 will also be reset simultaneously, so that the grinding block 14 no longer contacts the aluminum plate. Then, the aluminum plate is driven forward a distance by the electric slide rail 5, and then the electric push rod 9 is activated to drive the pushing plate 10 to push the aluminum plate, which makes it easier to remove the aluminum plate.

[0026] like Figure 1 , Figure 5 As shown, spring telescopic rods 17 are fixedly connected to both sides of the support frame 1. A fixing block 18 is fixedly connected to the telescopic end of the spring telescopic rods 17. A grinding block 19 is fixedly connected to the fixing block 18. When the grinding block 19 contacts the receiving plate 8, the spring telescopic rods 17 are in a compressed state. When the electric slide rail 5 is activated, the receiving plate 8 passes through the through slot of the support frame 1. The grinding block 19 will contact both sides of the aluminum plate to grind and polish both sides of the aluminum plate, further improving the extrusion molding effect. The inclined surface on the grinding block 19 can facilitate the resetting of the grinding block 19 when the receiving plate 8 is moved to the underside of the pressure plate 4 by the electric slide rail 5 after the aluminum plate is removed.

[0027] Working principle: When extrusion is required, the heated aluminum billet is first placed on the receiving plate 8, and then several cylinders 3 are activated to extend and drive the pressure plate 4 to approach and extrude the aluminum billet. At this time, the receiving plate 8 and the support frame 1 cooperate to form a closed groove, and then the aluminum billet will be extruded and shaped in the groove. During the extrusion process, the receiving plate 8 will contact the inner bottom side of the support plate 2. At this time, the spring telescopic rod 7 is in a deformed state, and then the cylinder 3 will continue to extend to extrude the aluminum billet. Finally, the horizontal height of the formed aluminum plate will be consistent with the horizontal height of the receiving plate 8.

[0028] After extrusion, several cylinders 3 can be activated to retract, moving the pressure plate 4 away from the aluminum plate. At this time, the receiving plate 8 is no longer pushed by the pressure plate 4, and the spring telescopic rod 7 will reset, slightly lifting the receiving plate 8 so that the bottom side of the receiving plate 8 no longer contacts the support frame 1, thus making the receiving plate 8 slide more smoothly. When the pressure plate 4 completes the extrusion and is moved upward by the retraction of the cylinder 3, the upper side of the pressure plate 4 will contact the baffle 16. Then, the electric slide rail 5 is activated, allowing the receiving plate 8 to pass through the through slot of the support frame 1. During the passage process, the cylinder 3 continues to retract, and the baffle 16 will be pushed by the pressure plate 4 and rotate to push the positioning plate 12. At this time, the spring telescopic rod 11 will be in a retracted state, and the grinding block 14 will contact the top side of the aluminum plate. The retracting rod 13 will also retract and deform, so that the grinding block 14 will always be in contact with the aluminum plate. At this time, the electric slide rail 5 will be activated to move the aluminum plate away from the lower side of the pressure plate 4, so that the top side of the aluminum plate can be ground and polished, thereby improving the extrusion forming effect. After grinding, the cylinder 3 will be activated to extend, and the top plate will no longer push the positioning plate 12. The spring telescopic rod 11 and the spring telescopic rod 13 will also be reset simultaneously, so that the grinding block 14 will no longer be in contact with the aluminum plate. Then, the aluminum plate will be driven forward a distance by the electric slide rail 5. Then the electric push rod 9 can be activated to extend, and then the electric push rod 9 will drive the pushing plate 10 to contact the aluminum plate and make the aluminum plate slide on the receiving plate 8, so that the aluminum plate and the receiving plate 8 are misaligned. At this time, the aluminum plate can be removed more easily.
