[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-6 The utility model provides a technical solution: a high-efficiency multi-station bending machine, including a mounting pad 1 and a mounting frame 2, the mounting frame 2 is fixedly arranged on the top of the mounting pad 1, and the bending processing template 3 is rotatably connected between the two sides of the inner cavity of the mounting frame 2 by a rotating shaft. Both sides of the inner cavity of the mounting frame 2 are fixedly connected to angle limit blocks 14 used in conjunction with the bending processing template 3. A plurality of placement slots 4 are opened on the top of the bending processing template 3, and a bending adaptation slot 5 is opened on the top of the bending processing template 3 and located on the rear side of the placement slot 4. A bending mechanism 6 used in conjunction with the bending adaptation slot 5 is provided inside the mounting frame 2. The bending mechanism 6 includes a second electric telescopic rod 61, which is fixedly arranged inside the mounting frame 2, and the bottom of the extending end of the second electric telescopic rod 61 is fixedly connected to a bending plate 62 used in conjunction with the bending adaptation slot 5. The front side of the mounting frame 2 is fixedly connected to a first electric telescopic rod 7 through a bracket, and the bottom of the extending end of the first electric telescopic rod 7 is fixedly connected to a pressing plate 8.

[0020] Furthermore, in order to facilitate the pressing and unloading of the shifting plate, L-shaped frames 9 are fixedly connected on both sides of the front side of the pressing plate 8. The surface of the L-shaped frame 9 is provided with a pulling mechanism 10 used in conjunction with the bending processing template 3. The pulling mechanism 10 includes a U-shaped mounting frame 101. The U-shaped mounting frame 101 is fixedly provided on the rear side of the bending place of the L-shaped frame 9. The interior of the U-shaped mounting frame 101 is rotatably connected to a lifting plate 102 through a rotating shaft. The front side of the bending processing template 3 is fixedly connected with a retaining edge 103 used in conjunction with the lifting plate 102.

[0021] Among them, in order to facilitate the rapid spreading of the lifting plate 102, the rear side of the bending part of the L-shaped frame 9 is fixedly connected to the limiting sleeve 11, and the internal sliding connection of the limiting sleeve 11 is connected to the limiting top rod 12 used in conjunction with the lifting plate 102, and a return spring 13 is fixedly connected between the limiting top rod 12 and the limiting sleeve 11.

[0022] When in use, several metal sheets are placed in the corresponding placement slots 4 in sequence, and the first electric telescopic rod 7 is started. The first electric telescopic rod 7 starts its extended end to drive the pressing plate 8 and the L-shaped frame 9 to descend until the pressing plate 8 is pressed against the top of the numerous thin plates. When the L-shaped frame 9 descends along with the pressing plate 8, the L-shaped frame 9 synchronously drives the U-shaped mounting frame 101 and the lifting plate 102 to descend. During the descent of the lifting plate 102, its bottom will be squeezed and contacted with the top of the retaining edge 103, prompting the lifting plate 102 to retract its angle over the retaining edge 103 and reset the expansion angle accordingly at the bottom of the retaining edge 103, and then start the bending mechanism 6 bends the paddle plates. After the bending is completed, the bending mechanism 6 and the first electric telescopic rod 7 are reset in sequence. The reset of the first electric telescopic rod 7 drives the pressing plate 8, the L-shaped frame 9, and the lifting plate 102 to rise. The lifting plate 102 rises and lifts the retaining edge 103. The retaining edge 103 lifts the bending processing template 3, prompting the bent thin plate to be tilted for unloading. As the rotation angle of the bending processing template 3 changes, the retaining edge 103 gradually disengages from the lifting plate 102. After the retaining edge 103 disengages from the lifting plate 102, the corresponding bending processing template 3 and the retaining edge 103 are reset to their original positions by their own weight, waiting to receive the next batch of thin plates.
