[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] As shown in the figure, a capacitor box automatic bending device includes:

[0040] The front feeding mechanism 1 and the rear feeding mechanism 2 are used for automatically feeding the box body plate, wherein the specific structures of the front feeding mechanism 1 and the rear feeding mechanism 2 are as follows Figure 9-10 As shown, they all include a workbench 101, a pusher frame 102 located above the workbench 101 and capable of moving forward and backward, and a movable support plate 103 ( Fig.10 The movable support plate 103 of the middle and rear feeding mechanism 2 is not shown). Specifically, the pushing rack 102 at the front and rear positions is driven forward and backward by the motor and screw installed under the workbench 101, which will not be described in detail here.

[0041] The main working principle of the front feeding mechanism 1 and the rear feeding mechanism 2 is: place the plate on the workbench 101 of the front feeding mechanism 1, and use the pushing rack 102 to push the plate toward the direction of the main frame 3. During the bending process, the pushing racks 102 in the front and rear directions can cooperate in feeding according to the different bending positions of the plate. When one side serves as the main pushing part, the other side serves as a limit part of the plate, so that the size can be accurately controlled.

[0042] In addition, the movable support plate 103 is mainly used to play the role of movable support, and has working states in both horizontal and vertical directions. It is flipped and controlled by the air cylinder or oil cylinder below. In the horizontal state, it is used to support the plate so that the plate can smoothly enter the working area (where the main frame 3 is located) to avoid falling. In the vertical state, it is used to make way to avoid interference between the flipping plate 11 and the movable support plate 103 during subsequent bending work.

[0043] The main frame 3 is located between the front feeding mechanism 1 and the rear feeding mechanism 2 .

[0044] Inside the main frame 3, on one side close to the front feeding mechanism 1 and the rear feeding mechanism 2, a reversible turning plate 11 is provided, and between the two turning plates 11 there is a lower fixed plate 14 fixedly connected to the main frame 3; above the main frame 3 there is a crossbeam 9 that can be raised and lowered, and below the crossbeam 9 and above the lower fixed plate 14 there is an upper pressing plate 7 that cooperates with the lower fixed plate 14 to press the sheet material. When working, the two turning plates 11 successively bend the sheet material 90°, and when bending, the upper pressing plate 7 and the lower fixed plate 14 are used to press and fix the sheet material.

[0045] A push block 8 that can move in the horizontal direction is provided on the cross beam 9. In this example, the push block 8 is a moving block on a rodless cylinder, that is, the rodless cylinder is used as a power element to enable the push block 8 to move in the horizontal direction. When the box bending work is completed, the box as a whole can surround the cross beam 9. At this time, the push block 8 can push the box to move horizontally under the action of the air source. In addition, the horizontal movement of the push block 8 can also be achieved by using a traditional cylinder with a telescopic rod or a motor connected to a screw.

[0046] A flip frame 13 that can flip outward is provided on one side of the main frame 3. After the box bending work is completed, the box can be placed on the beam 9, and the box is pushed outward by the pushing block 8 on the beam 9. After the flip frame 13 is flipped, the box is guided outward from the position where the flip frame 13 is located.

[0047] Specifically, Figure 5 As shown, the two flipping plates 11 are installed inside the main frame 3 via the rotating shaft 16 , that is, the two flipping plates 11 have the freedom to rotate along the center line of the rotating shaft 16 .

[0048] A vertical connecting shaft 17 is installed at the front and rear ends of the two flipping plates 11. The connecting shaft 17 passes through the flipping plates 11 and the flipping plates 11 can move along the axial direction of the connecting shaft 17. The upper end of the connecting shaft 17 is sleeved on the rotating shaft 16, and the outer part of the connecting shaft 17 is sleeved with a spring 18. One end of the spring 18 abuts against the step in the circumferential direction of the connecting shaft 17, and the other end abuts against the upper end of the nut 15 installed at the lower end of the flipping plate 11. The purpose of this arrangement is to avoid damage to the steel plate or the flipping plate 11 during the bending process of the steel plate, so that the flipping plate 11 can move slightly along the axial direction of the connecting shaft 17 when flipping, so as to better achieve the bending effect.

[0049] Specifically, a turning cylinder 12 is installed below the turning plate 11, which can drive the two turning plates 11 to turn over. Figure 4-5 As shown, one of the flipping cylinders 12 is not shown in the figure. The lower end of the flipping cylinder 12 is connected to the main frame 3, and the upper end of the telescopic rod of the flipping cylinder 12 is hinged at the inner side of the flipping plate 11, that is, the flipping action of the flipping plate 11 is realized by the flipping cylinder 12 as the power. The two flipping cylinders 12 each control a flipping plate 11 to flip, completing the bending action. Since two flipping cylinders 12 and two flipping plates 11 are provided, the bending work of the box can be completed more quickly, thereby improving work efficiency.

[0050] Specifically, the lower end of the flip frame 13 is hinged at the outer side of the main frame 3, and a horizontal shaft 20 is installed on the outer side of the flip frame 13. The horizontal shaft 20 is connected to the driving cylinder 21 located on the outer side of the main frame 3. The driving cylinder 21 can drive the horizontal shaft 20 and the flip frame 13 to flip when working. This arrangement is to enable the flip frame 13 to flip outward 90° after the box bending work is completed, so that an exit is formed on one side of the main frame 3 to facilitate the box to be exported.

[0051] Specifically, a guide rail slider mechanism 19 is installed inside the flip frame 13 and on the main frame 3 on the side away from the flip frame 13. The slider of the guide rail slider mechanism 19 can move in the vertical direction. When the flip frame 13 is in a vertical state, the slider of the guide rail slider mechanism 19 can move in the vertical direction, and when the flip frame 13 is flipped outward by 90°, the slider does not move.

[0052] One of the sliders is fixedly connected to one end of the beam 9, and a block 23 is installed on the other slider. The other end of the beam 9 can be inserted into the center hole of the block 23. The purpose of this arrangement is that the flip frame 13 has a flipping function. Therefore, it is necessary to form a detachable connection between the beam 9 and the flip frame 13. During operation, the end of the beam 9 is placed at the center hole of the block 23, and the lifting cylinders 10 on both sides can normally drive the beam 9 to perform lifting work. After the work is completed and the flip frame 13 is flipped, the block 23 can be detached from the end of the beam 9 to facilitate the outward export of the box. After the box is completely exported, the flip frame 13 resumes its vertical state, so that the end of the beam 9 is placed in the center hole of the block 23 again.

[0053] A connecting frame 22 is installed on the upper end of the block 23 and on the side of the beam 9 away from the block 23. The connecting frame 22 is connected to the upper lifting cylinder 10, that is, the lifting cylinder 10 serves as a driving source for the up and down movement of the beam 9 to facilitate the up and down movement of the beam 9.

[0054] Specifically, the end of the beam 9 away from the flip frame 13 extends outward, and two limit screws 5 are installed on the main frame 3, and a limit block 6 is installed on the limit screw 5. The limit block 6 is located directly above the end of the beam 9. This arrangement is to limit the highest point of the beam 9 to avoid the situation where the box cannot be surrounded by the beam 9.

[0055] Specifically, protective covers 4 are installed outside the front feeding mechanism 1 , the rear feeding mechanism 2 and the main frame 3 .

[0056] When the automatic bending device for capacitor box is working, the front feeding mechanism 1 pushes the plate into the main frame 3, specifically between the upper pressing plate 7 and the lower fixing plate 14. At this time, the turning plates 11 on both sides of the lower fixing plate 14 bend the plate successively. The bending process is as follows: Fig.11 As shown by the arrow, after the plate is bent, it finally forms an overall box-type structure, which can be surrounded by the outside of the beam 9. After the turning frame 13 is turned 90°, the pushing block 8 is used to push the box from the beam 9 to complete the entire processing process.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
