[0015] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0016] like Figure 1-Figure 8 The electric loader plate material bending prefabrication processing device shown in the figure comprises a base 1, a forming die 3 is fixedly installed on the upper surface of the base 1, a connecting frame 18 is fixedly installed on the upper surface of the base 1 near the rear of the forming die 3, a lifting plate 9 is installed on the front surface of the connecting frame 18 through a pressing mechanism, a punching die 5 is installed on the lower surface of the lifting plate 9 through a lifting mechanism, a hidden groove 8 is opened on the inner top surface of the punching die 5, the inner top surface of the hidden groove 8 slides through the plug plate 6, and the upper end of the plug plate 6 is fixedly connected to the lower surface of the lifting plate 9, and the lower end of the plug plate 6 is fixedly connected to the pressing plate 7, side baffles 13 are respectively arranged on both sides of the upper part of the base 1 and near the forming die 3, and a telescopic mechanism is arranged at the rear end between the two side baffles 13; The upper surface of the forming die 3 is fixedly connected with a rear baffle 4, and when the punching die 5 moves downward, the rear surface slides and contacts the front surface of the rear baffle 4, thereby preventing interference problems from occurring during punching and blocking the downward movement of the punching die 5.

[0017] After the stamping die 5 moves downward, the pressing plate 7 is slidably embedded into the inner side of the recess 8 to prevent a concave position from being formed on the upper surface of the molded shell 31 after stamping.

[0018] The flat plate 30 is placed on the upper surface of the forming die 3 , and the two sides are blocked by the side baffles 13 . After the pressing plate 7 presses the upper surface of the flat plate 30 , the stamping die 5 moves downward to perform stamping and forming.

[0019] like Figure 1 , Figure 2 As shown, the pressing mechanism includes a lifting beam 23 mounted on the inner side of the connecting frame 18 along the vertical sliding direction, a mounting platform 24 is fixedly connected to the front surface of the lifting beam 23, a reinforcing plate 25 is fixedly embedded in the front side of the mounting platform 24, and the reinforcing plate 25 is fixedly mounted on the upper surface of the lifting plate 9. A vertical cylinder 21 is fixedly mounted at the inner upper end of the connecting frame 18, and the telescopic end of the vertical cylinder 21 is fixedly connected to the upper surface of the lifting beam 23. The lifting beam 23 is controlled to move up and down by the telescopic movement of the vertical cylinder 21. The design of the mounting platform 24 and the reinforcing plate 25 enables the lifting plate 9 to be relatively located in front of the connecting frame 18, thereby ensuring that the stamping die 5 is located in front of the connecting frame 18 and does not interfere with the connecting frame 18.

[0020] Two vertical rails 19 are fixedly installed on the inner side of the connecting frame 18, and the lifting beam 23 is located between the two vertical rails 19. Slides 22 are fixedly installed on the two side surfaces of the lifting beam 23, respectively. The slides 22 and the vertical rails 19 slide together in the vertical direction. A fixed plate 20 is fixedly connected between the adjacent sides of the two vertical rails 19, and the upper end of the vertical cylinder 21 is fixedly penetrated through the surface of the fixed plate 20. The cooperation between the vertical rail 19 and the slide 22 is used to improve the stability of the lifting beam 23 when it moves up and down. The fixed plate 20 provides a position for the fixed installation at the upper end of the vertical cylinder 21.

[0021] like Figure 4 As shown, the lifting mechanism includes a lifting cylinder 10 fixedly embedded on one side of the upper surface of the lifting plate 9, the telescopic end of the lifting cylinder 10 is fixedly connected to the upper surface of the stamping die 5, and a guide cylinder 11 is fixedly embedded on the other side of the upper surface of the lifting plate 9, and a guide rod 12 is slidably inserted at the lower end of the guide cylinder 11, and the lower end of the guide rod 12 is fixedly connected to the upper surface of the stamping die 5. When the lifting cylinder 10 is extended and retracted, the guide rod 12 will slide relatively along the inner side of the guide cylinder 11 to ensure the stability of the stamping die 5 when it moves up and down.

[0022] like Figure 5As shown, the telescopic mechanism includes a plurality of brackets 15 fixedly mounted on the upper surface of the base 1, and a bidirectional cylinder 14 is fixedly mounted on the upper ends of the plurality of brackets 15, and the two telescopic ends of the bidirectional cylinder 14 are respectively fixedly connected to the side surfaces of the side baffle 13. The bracket 15 is used to fix the bidirectional cylinder 14 at a suitable height.

[0023] like Figure 6 As shown, the two side surfaces of the connecting frame 18 are respectively fixedly connected with supporting plates 16, and the upper surface of the supporting plate 16 is fixedly connected with a sleeve plate 17, and the telescopic end of the two-way cylinder 14 slides through the side surface of the sleeve plate 17. The supporting plate 16 plays the role of supporting the side baffle 13 to prevent the vertical moment from acting on the telescopic end of the two-way cylinder 14 and causing damage, and the sleeve plate 17 is used to guide the lateral movement of the telescopic end of the two-way cylinder 14 to improve the stability during telescopic movement.

[0024] like Figure 5 As shown, a plurality of reinforcing frames 29 are fixedly connected between the rear surface of the connecting frame 18 and the upper surface of the base 1 to improve the stability of the connecting frame 18. Figure 3 As shown, two lower sides of the forming mold 3 are respectively fixedly connected with connecting plates 2, and the connecting plates 2 are fixedly mounted on the upper surface of the base 1 to improve the stability of the forming mold 3.

[0025] like Figure 1 , Figure 5 As shown, the corners of the two side surfaces of the base 1 are fixedly connected with foot seats 26, the upper surface of the foot seats 26 is threaded with a threaded rod 27, and the lower end of the threaded rod 27 is fixedly connected with a foot pad 28. By rotating the threaded rod 27, the threaded rod 27 can be moved up and down relative to the foot seats 26, thereby changing the height of the foot pad 28 to adapt to the uneven ground for stable placement.

[0026] The user places the flat plate 30 on the upper surface of the forming mold 3, with the two sides blocked by the side baffles 13 respectively, and the rear side of the flat plate 30 is blocked and limited by the rear baffle 4. By controlling the extension and contraction of the two-way cylinder 14, the distance between the two side baffles 13 is controlled to ensure that the packaging can be precisely positioned with the flat plate 30. The state after placement is as follows: Figure 7 As shown, therefore, the flat plate 30 has the function of being quickly positioned and placed, thereby improving processing efficiency.

[0027] After the flat plate 30 is arranged, the vertical cylinder 21 is controlled to extend so that the pressing plate 7 is pressed on the surface of the flat plate 30, and then the lifting cylinder 10 is controlled to extend so that the stamping die 5 moves downward. Under the cooperation of the stamping die 5 and the forming die 3, the flat plate 30 is stamped to form a forming shell 31. During this process, the pressing plate 7 will move relatively to the inside of the groove 8 to ensure the flatness of the top surface of the stamping die 5 and the upper surface of the forming shell 31. Figure 8As shown, the shape of the molded shell 31 after stamping is shown. Therefore, the flat plate 30 can be stamped quickly, avoiding the inconvenience caused by multiple bending and forming in the traditional process, and improving the processing efficiency.

[0028] After the forming shell 31 is stamped, the lifting cylinder 10 is preferentially controlled to retract, driving the stamping die 5 to move upward, so that the forming shell 31 is separated from the inner side of the stamping die 5. After that, the vertical cylinder 21 is controlled to retract, so that the pressing plate 7 is moved upward. Then, the user can move the forming shell 31 forward to separate it from the surface of the forming die 3, thereby achieving the purpose of rapid demolding and preventing jamming problems from occurring.
