[0048] preferred;

[0049] like Figure 8 As shown, the moving assembly includes a mounting box 41, which is fixedly mounted on the surface of the base 1, an electric slide 42 is fixedly mounted on the bottom of the inner cavity of the mounting box 41, a bracket 43 is fixedly mounted on the moving end of the electric slide 42, and a limiting hole is provided on the top of the mounting box 41 to facilitate support and connection of internal components, and the required position can be adjusted according to the movement of the electric slide 42, and the setting of the limiting hole can ensure that the outer cylinder 49 is not obstructed when moving.

[0050] like Figure 9 As shown, the rotating assembly includes a connecting frame 44, which is fixedly mounted on one side of the bracket 43, and a fixing rod 45 is fixedly mounted on the inner side wall of the base 1. The connecting frame 44 slides on the outside of the fixing rod 45, and a motor 46 is fixedly mounted on the top of the connecting frame 44. The output shaft key of the motor 46 is connected to the first bevel gear 47, and the bottom of the first bevel gear 47 is engaged with the second bevel gear 48, which has the advantage of direction adjustment and completes the direction adjustment operation by using rotational output force and meshing transmission to meet people's needs.

[0051] like Figure 10 As shown, the jacking assembly includes an outer cylinder 49, which is fixedly mounted on the inner wall of the second bevel gear 48, and the inner wall of the outer cylinder 49 is respectively provided with a limit groove 410 and a slide groove 411, the inner sliding connection of the limit groove 410 is connected to the limit block 413, the inner sliding connection of the slide groove 411 is connected to the slide bar 412, the inner side of the slide bar 412 is fixedly mounted with an inner cylinder 414, the inner side of the limit block 413 is fixed to the inner cylinder 414, the bottom end of the outer cylinder 49 is rotatably connected to the top of the bracket 43, and the top of the bracket 43 is fixedly mounted with a third electric push rod 415, the output end of the third electric push rod 415 is rotatably connected to the top of the inner cavity of the inner cylinder 414, which has the advantage of height adjustment, and the adjustment operation is completed by directly lifting the third electric push rod 415 to adapt to the moving height of the formed liner above.

[0052] further;

[0053] like Figure 5 As shown, the support assembly includes a connection box 31 and a mounting bracket 314. The mounting bracket 314 is fixedly installed on the top of the inner cylinder 414. The connection box 31 is fixedly installed on the inner wall of the mounting bracket 314. A first through-hole 34 is provided on the top of the connection box 31, which has a supporting effect to ensure the stable operation of various internal and external components.

[0054] like Figure 5 As shown, the pushing assembly includes a second electric push rod 32, which is fixedly mounted on the top of the connecting box 31. A push plate 33 is fixedly mounted on the output end of the second electric push rod 32. The push plate 33 is located inside the first through-hole 34 to facilitate adjustment of the required spacing between the two sets of side panels 312. Pushing is used as the power for adjustment.

[0055] like Figure 7 As shown, the transmission assembly includes a crossbar 35, which is rotatably connected to the inner wall of the connecting box 31. A first gear 36 is fixedly mounted on the outer side of the crossbar 35, and a toothed plate 37 is meshed with the outer side of the first gear 36. A first support rod 38 is also fixedly mounted on the inner side wall of the connecting box 31. The toothed plate 37 slides on the outer side of the first support rod 38, and the spacing is adjusted according to the meshing transmission.

[0056] A mounting plate 39 is fixedly installed on the outer end of the tooth plate 37, and a second support rod 310 is also fixedly installed on the inner wall of the connecting box 31. The mounting plate 39 slides on the outside of the second support rod 310. Second through holes 311 are provided at both ends of the surface of the connecting box 31. A side plate 312 is fixedly installed on one end of the mounting plate 39, and a connecting strip 313 is fixedly installed on the top of the inner side of the side plate 312. The sliding support method is used to ensure the stability of the spacing adjustment and movement.

[0057] When receiving the material, the electric slide 42 works directly and drives the components on its top to move together and move to the preset required position, that is, the position shown in the figure. Of course, the actual position can be fine-tuned according to the actual situation during on-site processing. Then the third electric push rod 415 works, and the lifting force of the third electric push rod 415 directly pushes the inner cylinder 414 to move upward. When the inner cylinder 414 moves upward, the limit block 413 slides inside the limit groove 410 to limit the upward movement. At the same time, the slide bar 412 slides inside the slide groove 411 to ensure that the subsequent rotation force can be transmitted. During the lifting process, the material-retrieving mechanism 3 is directly driven to be at the bottom of the formed part;

[0058] At the same time, the second electric push rod 32 works, and the upper gear plate 37 is pushed by the second electric push rod 32 to move, and the lower gear plate 37 is driven to move at the same time according to the meshing transmission of the first gear 36, until the distance between the two sets of gear plates 37 is reduced. Conversely, the distance between the two sets of gear plates 37 can be increased by pulling it outward.

[0059] Adjusting the spacing between the two sets of tooth plates 37 not only achieves the effect of receiving the material, but also allows the material to be placed on top of the bottom die 21 before stamping and forming. When the position is offset, the two sets of tooth plates 37 can be moved simultaneously to achieve lateral pushing, so that the material is placed in the middle position, which is convenient for subsequent stamping and forming operations.

[0060] After receiving the material, the third electric push rod 415 retracts and drives the formed inner liner to the initial height, and then the electric slide 42 moves back and moves to the required position. The required direction can be adjusted during the movement. At this time, the motor 46 works and uses the motor 46 to drive the first bevel gear 47 to rotate. The first bevel gear 47 and the motor 46 are connected by a shaft, and the shaft is supported by a vertical plate connected by rotation to ensure the stability of the rotation. When the first bevel gear 47 rotates, it engages and drives the second bevel gear 48 to rotate, and the second bevel gear 48 will directly drive the outer cylinder 49 to rotate. Since the outer cylinder 49 and the inner cylinder 414 are connected in a sliding manner, it can not only ensure up and down sliding, but also ensure the transmission of rotational force during rotation, so that the required direction can be adjusted. After the direction is adjusted, it can be moved up and placed on the conveyor, and then returned to the initial position for subsequent repeated operations.

[0061] at last;

[0062] like Figure 2 As shown, the stamping mechanism 2 includes a forming component and an anti-jamming component. The forming component is arranged on the top of the base 1, and the anti-jamming component is arranged on the inner side of the forming component.

[0063] like Figure 2 As shown, the forming assembly includes a bottom mold 21, which is bolted to the top of the base 1. Columns 22 are fixedly installed around the top of the base 1. A top plate 23 is fixedly installed on the top of the column 22. A first electric push rod 24 is bolted through the top of the top plate 23. The output end of the first electric push rod 24 is bolted to a top mold 25. The top mold 25 is slidably connected to the column 22, which can directly realize the stamping and forming operation of the aluminum alloy liner of the digital display cabinet to ensure the stamping operation.

[0064] The anti-stuck component includes a connecting rod 26, which is fixedly mounted at both ends of the bottom of the top plate 23. Springs 27 are welded at both ends of the top of the top mold 25. A circular plate 28 is fixedly mounted on the top of the spring 27, and a push rod 29 is fixedly mounted on the bottom of the circular plate 28. The spring 27 is located on the outside of the push rod 29. The push rod 29 is slidingly penetrated between the top mold 25. The thrust generated during the upward and moving process can push the aluminum alloy liner stuck on its outside away from the top mold 25, preventing it from being stuck on its outside continuously, facilitating its stripping and preventing it from being stuck continuously.

[0065] During stamping, the two groups of first electric push rods 24 work directly, and a synchronous controller can be used between the two groups of first electric push rods 24 to ensure the synchronization effect during pushing and pulling, including the above-mentioned synchronization method but not limited to the above-mentioned synchronization method. After the top mold 25 is pushed, it is continuously pressed down until it contacts the material and adapts to the bottom mold 21 to complete the stamping operation, and then moves upward. At this time, since the raw material is aluminum alloy, it is easy for the material to be stuck in the top mold 25 during the stamping process. When it continues to move upward, the circular plate 28 will contact the connecting rod 26. Continuous upward movement will compress the spring 27 through the circular plate 28, and drive the push rod 29 to penetrate the top mold 25 and push the inner liner stuck in the top mold 25, and make it separate from the top mold 25. During this process, the above-mentioned material picking mechanism 3 is already located at the bottom of the inner liner for support and reception, and the material picking and rotating operations are performed according to the above.

[0066] A molding method comprising the following steps:

[0067] S1, material stamping, the aluminum alloy part is placed on the top of the bottom mold 21, the first electric push rod 24 pushes the top mold 25 downward, and the aluminum alloy part is stamped and formed through the adaptation of the bottom mold 21;

[0068] S2, anti-stuck material operation: the formed material will be stuck on the outside of the top die 25 due to the adaptability of the stamping die. When the top die 25 moves upward, the stuck material will move synchronously. When the top die 25 continues to move upward, the circular plate 28 will contact the connecting rod 26 and compress the spring 27. At this time, the connecting rod 26 slides through the aluminum alloy at the bottom of the top die 25 and pushes it out of the top die 25;

[0069] S3, material receiving and feeding operation, during the material pushing process to prevent the material from getting stuck, the material is directly driven by the electric slide 42 and moved to the bottom of the aluminum alloy formed part. At this time, it moves up to the required height under the lifting of the third electric push rod 415, and the output operation of the motor 46 and the engagement of the first bevel gear 47 and the second bevel gear 48 can be adjusted to the required direction after taking the material. At the same time, the push and pull of the second electric push rod 32 can adjust the position spacing of the side plate 312 and the connecting bar 313 through the engagement of the first gear 36 and the tooth plate 37 to adapt to the aluminum alloy stamping parts dropped from above.

[0070] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
