[0016] The following is combined with Figure 1-10 This application is described in further detail.

[0017] The present application embodiment discloses a forming machine for aluminum plate processing. Figure 1 and Figure 2 As shown, the forming machine for aluminum plate processing includes a bracket 1, on which a stamping unit 2 and a support seat 3 are arranged in sequence from top to bottom. A limit frame 31 is installed on the upper surface of the support seat 3, and a blanking cavity 32 is provided at the center of the support seat 3.

[0018] During the stamping process of the aluminum plate, the aluminum plate will be placed on the upper surface of the support seat 3 and embedded in the limit frame 31, so that the aluminum plate is limited and fixed; the stamping unit 2 will stamp the center of the aluminum plate, and the stamping waste will fall through the blanking cavity 32.

[0019] A collecting box 33 may be placed directly below the blanking cavity 32 to collect the dropped stamping waste.

[0020] like Figure 2 and Figure 3 As shown, the stamping unit 2 includes a hydraulic cylinder 21 mounted on the bracket 1, the piston rod of the hydraulic cylinder 21 extends in the vertical direction and is connected to a mounting seat 22, and a punch head 23 is mounted on the mounting seat 22. During the stamping process of the aluminum plate, the hydraulic cylinder 21 will drive the mounting seat 22 to descend, and the punch head 23 on the mounting seat 22 will stamp the center of the aluminum plate.

[0021] Two pressing plates 24 are provided between the mounting seat 22 and the support seat 3, and the punching head 23 is located between the two pressing plates 24. The pressing plate 24 is connected to the mounting seat 22 through a second elastic telescopic rod 25, and the second elastic telescopic rod 25 is vertically arranged. Before the aluminum plate is stamped, the second elastic telescopic rod 25 will be in a natural state, and the lower surface of the pressing plate 24 will be lower than the lower surface of the punching head 23; when the aluminum plate is stamped, the pressing plate 24 will first be pressed against the upper surface of the aluminum plate, and the second elastic telescopic rod 25 will be gradually compressed, so that the pressing plate 24 presses the aluminum plate against the upper surface of the support seat 3, and then the punching head 23 stamps the aluminum plate, thereby improving the stability of the aluminum plate during the stamping process.

[0022] Two suction cups 26 are provided between each pressing plate 24 and the punching head 23, and the suction cups 26 are connected to the mounting seat 22 through a vertically arranged connecting pipe 27. Before the aluminum plate is punched, the second elastic telescopic rod 25 and the suction cups 26 will be in a natural state, and the lower surface of the suction cups 26 will be higher than the lower surface of the pressing plate 24 and lower than the lower surface of the punching head 23; during the punching process of the aluminum plate, the pressing plate 24 first presses the aluminum plate against the upper surface of the support seat 3, and the suction cups 26 are then sucked against the upper surface of the aluminum plate, and then the punching head 23 punches the aluminum plate again, thereby further improving the stability of the aluminum plate during the punching process.

[0023] like Figure 4 and Figure 5As shown, two vertically arranged first elastic telescopic rods 34 are provided directly below the blanking cavity 32, the fixed ends of the first elastic telescopic rods 34 are mounted on the bracket 1, and the telescopic ends of the first elastic telescopic rods 34 are rotatably connected with support plates 35. When the pressing plate 24 presses the aluminum plate against the support seat 3, the first elastic telescopic rods 34 will be in a natural state, the two support plates 35 will be in the blanking cavity 32 and support the bottom of the aluminum plate in a horizontal posture, and the stamping waste will fall from between the two support plates 35 into the collection box 33; the support plates 35 can stably support the center of the aluminum plate, so that the aluminum plate is not easily bent and deformed during the stamping process, and the center of the aluminum plate is prevented from being concave and stuck in the blanking cavity 32. like Figure 5 and Figure 6 As shown, the support plate 35 and the telescopic end of the first elastic telescopic rod 34 are connected to the same torsion spring 351, and the support plate 35 can be flipped on the vertical plane; the lower surface of the pressure plate 24 is provided with a groove 241, and the first magnetic block 242 is fixedly embedded in the groove 241.

[0024] After the pressing plate 24 presses the aluminum plate against the upper surface of the support seat 3, the pressing plate 24 and the supporting plate 35 will be clamped together on the aluminum plate. The material of the supporting plate 35 is iron. At this time, the first magnetic block 242 will adsorb and fix the supporting plate 35, and the torsion spring 351 will be in a deformed state; when the stamping of the aluminum plate is completed, the hydraulic cylinder 21 will drive the mounting seat 22 to rise, and the mounting seat 22 will drive the pressing plate 24 to rise; under the magnetic attraction of the first magnetic block 242, the supporting plate 35 will rise with the first magnetic block 242 and the pressing plate 24. Under the dual action of the upward thrust of the supporting plate 35 and the adsorption force of the suction cup 26, the aluminum plate will easily rise and break away from the inner side of the limit frame 31, and there is no need for workers to manually take the aluminum plate out of the limit frame 31 to facilitate subsequent unloading of the aluminum plate.

[0025] like Figure 7 and Figure 8 As shown, four baffles 11 arranged in a rectangular shape are installed on the bracket 1, and the baffles 11 are located on the rising trajectory of the aluminum plate. When the aluminum plate rises and contacts the baffles 11, the aluminum plate will temporarily remain still, and the aluminum plate will have been separated from the inner side of the limit frame 31, and the pressing plate 24 and the suction cup 26 will continue to rise and gradually separate from the aluminum plate; at this time, the first magnetic block 242 will no longer generate magnetic attraction on the support plate 35, and the first elastic telescopic rod 34 and the torsion spring 351 will gradually return to the natural state, and the first elastic telescopic rod 34 will cause the support plate 35 to descend, and the aluminum plate will descend with the support plate 35 due to its own gravity, and the torsion spring 351 will cause the support plate 35 to gradually flip to an inclined state, and the aluminum plate will also flip to an inclined state during the descent process, and at this time, the aluminum plate will slide down due to its own gravity and separate from the upper part of the limit frame 31, so that the stamped aluminum plate can be automatically unloaded.

[0026] like Figure 1As shown, workers can set a collecting plate 4 at the downward trajectory of the aluminum plate. The collecting plate 4 is set at an angle and is used to collect the aluminum plates that have been stamped. A limiting plate 41 is installed at the lower end of the collecting plate 4. The limiting plate 41 is used for the front end of the aluminum plate to contact, so that the aluminum plates that have been stamped can be stacked one by one on the upper surface of the collecting plate 4.

[0027] like Figure 8 and Fig. 9 As shown, the lower end of the connecting tube 27 is connected to the inside of the suction cup 26, and the upper end of the connecting tube 27 is open; a slide plate 271 is slidably penetrated in the horizontal direction on the connecting tube 27, and the slide plate 271 is connected to the connecting tube 27 through a spring 272, one end of the spring 272 is fixedly connected to the slide plate 271, and the other end of the spring 272 is fixedly connected to the connecting tube 27. During the stamping process of the aluminum plate, the spring 272 will be in a natural state, at which time the slide plate 271 will be inserted into the connecting tube 27 and separate the upper and lower parts of the connecting tube 27, so that the outside air cannot enter the lower part of the connecting tube 27, so as to ensure the suction effect of the suction cup 26 on the aluminum plate.

[0028] A second magnetic block 111 is installed on the baffle 11. When the aluminum plate rises and hits the baffle 11, the suction cup 26 will gradually detach from the upper surface of the aluminum plate. The slide plate 271 is made of iron. At this time, the second magnetic block 111 will adsorb and fix the slide plate 271, so that the slide plate 271 slides out of the inside of the connecting tube 27. External air can enter the suction cup 26 through the upper end of the connecting tube 27, so that the negative pressure inside the suction cup 26 disappears quickly, so that the suction cup 26 detaches from the upper surface of the aluminum plate, thereby preventing the suction cup 26 from deforming the aluminum plate due to excessive adsorption force.

[0029] like Fig.10 As shown, a guide plate 5 is installed on the bracket 1, and the guide plate 5 is inclined on the vertical plane. Side plates 51 are installed on both sides of the guide plate 5, and the two side plates 51 together surround a limit cavity 52. ​​During the feeding process of the aluminum plate, the worker will put the aluminum plate into the limit cavity 52, and the aluminum plate will slide downward in the limit cavity 52. ​​The front end of the aluminum plate will contact the front inner wall of the limit frame 31, so that the aluminum plate can be accurately embedded in the limit frame 31, which is convenient for feeding the aluminum plate.

[0030] A liftable door panel 53 is provided at the lower end of the guide plate 5, and the door panel 53 is connected to the side panel 51 through a vertically arranged third elastic telescopic rod 54. When the third elastic telescopic rod 54 is in a natural state, the door panel 53 will be at the lower end of the guide plate 5, and the aluminum plate on the upper surface of the guide plate 5 will be blocked by the door panel 53 in the limiting cavity 52, thereby realizing the preparation of the aluminum plate.

[0031] Two connecting plates 55 are installed on the door panel 53 for the mounting seat 22 to resist when it rises. The connecting plates 55 are set in an inverted "L" shape. When the mounting seat 22 drives the pressing plate 24 to rise and separate from the aluminum plate, the first elastic telescopic rod 34 will gradually return to a natural state, and the supporting plate 35 will also fall and flip back to reset. The mounting seat 22 will push the connecting plates 55 to rise during the rising process. The connecting plates 55 will drive the door panel 53 to rise and separate from the aluminum plate on the guide plate 5. The aluminum plate will directly slide down into the limit frame 31 and rest on the upper surface of the supporting plate 35, realizing automatic feeding of the aluminum plate.

[0032] The implementation principle of the forming machine for aluminum plate processing in the embodiment of the present application is as follows: during the stamping process of the aluminum plate, the aluminum plate will be embedded in the limit frame 31 and placed on the upper surface of the support seat 3 and the support plate 35, the hydraulic cylinder 21 will drive the mounting seat 22 to descend, the mounting seat 22 will drive the pressing plate 24, the suction cup 26 and the punching head 23 to descend, the pressing plate 24 will first press the aluminum plate to a horizontal state, so that the aluminum plate is pressed tightly against the upper surface of the support seat 3 and the support plate 35, and the suction cup 26 will then be sucked tightly against the aluminum plate , and then the punch head 23 punches the center of the aluminum plate, and the stamping waste will fall into the collection box 33 through the blanking cavity 32; during the descending process of the mounting seat 22, the mounting seat 22 will gradually separate from the connecting plate 55, and the worker can place the next aluminum plate to be punched in the limiting cavity 52, and the door panel 53 will drop to the lower end of the guide plate 5 due to the rebound force of the third elastic telescopic rod 54, so that the next aluminum plate to be punched is ready in the limiting cavity 52.

[0033] Then the hydraulic cylinder 21 will drive the mounting seat 22 to rise. Since the first magnetic block 242 adsorbs and fixes the support plate 35, the support plate 35 and the suction cup 26 will jointly drive the aluminum plate to rise, so that the aluminum plate is separated from the inner side of the limit frame 31, until the upper surface of the aluminum plate hits the baffle 11. At this time, the aluminum plate will not be able to continue to rise, and the pressure plate 24 will gradually separate from the upper surface of the aluminum plate. The second magnetic block 111 will adsorb and fix the slide plate 271, so that the slide plate 271 slides and separates from the inside of the connecting pipe 27. The external air can enter the suction cup 26 through the upper end of the connecting pipe 27, so that the negative pressure inside the suction cup 26 disappears quickly, so that the suction cup 26 gradually The torsion spring 351 will cause the support plate 35 to gradually flip over to an inclined state, so that the aluminum plate on the upper side of the support plate 35 tilts and slides down onto the collecting plate 4; in addition, the mounting seat 22 will push the connecting plate 55 to rise as it continues to rise, and the connecting plate 55 will drive the door panel 53 to rise and separate from the aluminum plate on the guide plate 5, and the aluminum plate will directly slide down into the limit frame 31 and rest on the upper surface of the support plate 35 after it has been lowered and reset.

[0034] In summary, workers only need to control the hydraulic cylinder 21 and complete the preparation of the aluminum plate during the aluminum plate stamping process to achieve automatic and precise loading of the aluminum plate, automatic limit fixation, automatic stable stamping, automatic waste collection, automatic limit release, automatic unloading and automatic stacking, thereby improving the processing and forming efficiency of the aluminum plate.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
