[0002] With the development of industry, sheet metal has been used in all walks of life, and traditional sheet metal bending technology often requires workers to come into close contact with the bending device to load materials, which will cause certain safety problems for workers. In addition, the traditional sheet metal bending technology has a single function and generally only performs a single bending process. The overall work efficiency is low, and the open sheet metal bending often exposes the entire bending device to the air. If the time is too long, some important parts will be oxidized, thereby reducing the service life of the entire bending device. In addition, after processing the workpiece, workers are generally required to pick up the workpiece manually, and the workpiece cannot be automatically dropped into the storage device, which not only affects the processing efficiency, but also causes additional safety problems for workers.

[0036] When the present invention is in use, when a worker puts a workpiece into the feed hopper 13, the workpiece enters the interior of the bending platform 1 along the feed port 12 under the action of gravity, and the workpiece is limited to the corresponding work position under the action of the limit plate 15. When the push motor 21 is energized, the cam 22 is driven to rotate through the active shaft 211. When the cam 22 rotates, the rotating rod 23 is driven by the cam 22 to rotate around the rotating pin 231. At this time, the return spring 24 is compressed. When the rotating rod 23 rotates, the push rod 25 is driven to move through the connecting pin 232. The push rod 25 pushes the slide plate 26 to move along the slide rail 16 provided on the bending platform 1, thereby pushing the slide plate 26 through the connecting rod 27. The push plate 28 moves, and the workpiece is pushed under the clamping mechanism 3.

The rotation of the gear 42 drives the rack top rod 51 to move upward. At this time, the rack top rod 51 drives the pressure rod 53 to rotate around the support pin 54 through the connecting column 52. When the pressure rod 53 moves, it pushes the bending arm 55 to move downward. At this time, the retraction rod 57 located on the right side of the bending arm 55 pushes the bending pressure rod 58 located on the right side to move downward under the action of the compression spring 56, thereby pushing the bending pressure block 59 located on the right side to move downward. At the same time, the bending arm 55 is also moved downward by the bending pressure rod 58 located on the right side. The bending pressure rod 58 on the left side pushes the bending pressure block 59 on the left side to move downward. When the lower surface of the bending pressure block 59 is displaced to be flush with the upper surface of the workpiece, the bending pressure block 59 on the right side will not continue to move downward under the action of the compression spring 56. At this time, the bending pressure block 59 on the right side presses the workpiece against the upper surface of the bending pad 17. At this time, the bending pressure block 59 on the left side continues to move downward to bend the workpiece along the edge of the bending pad 17. When the bending process is completed, the bidirectional motor 4 rotates in the opposite direction. At this time, the clamping mechanism 3 and the bending mechanism 5 return to their original positions. When the bending process of the next workpiece is carried out, the workpiece that has been bent in the previous process falls into the storage box 11 under the push of the unbent workpiece.
