[0015] Beneficial effects of the utility model:

[0016] The utility model drives the rotating rod one to rotate by starting the motor. Since a chain is sleeved between the outer end of the sprocket one and the outer end of the sprocket two, when the rotating rod one rotates, it will drive the rotating rod two to rotate in the same direction. At this time, when the protruding ends of the side ends of the water drop plate one and the water drop plate two rotate to the top of the lower pressure plate, they will push the lower pressure plate to move downward, and at the same time, they will also drive the pressure plate and the bending plate to move downward together. Since the metal product is transmitted to the top of each bending groove through the transmission device, and when the pressure plate moves downward, the pressure plate and the roller will press against the top of the metal product, thereby limiting the top of the metal product. At this time, the cylinder is started to drive the bending plate to move downward, so that the metal product can be bent in accordance with the bending groove. During the bending process, due to the pressure of the pressure plate and the roller on the metal product, the bending plate can avoid displacement and tilting of the metal product when it is pressed down and bent, thereby avoiding the quality of the bent metal product being good or bad, thereby reducing the production cost.

[0029] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the rebound mechanism includes a round rod 4, which is fixedly connected to the top of the machine body 2, and a round plate 401 is fixedly connected to the bottom of the round rod 4. A spring 402 is sleeved on the outer end of the round rod 4, and a lower pressure plate 5 is sleeved on the outer end of the round rod 4. The bending assembly includes a cylinder 501, which is fixedly installed on the bottom end of the lower pressure plate 5, and a bending plate 502 is fixedly installed on the bottom end of the cylinder 501. When the rotating mechanism presses the lower pressure plate 5 to move downward, the pressing plate 601 and the roller 602 will limit the top of the metal product to limit it, and at this time, the cylinder 501 is started to drive the bending plate 502 to move downward, so as to realize the bending of the metal product.

[0030] As an implementation method in this embodiment, Figure 1 and Figure 3As shown, the rotating mechanism includes a motor 3, which is fixedly mounted on the inner side end of the mounting groove 202, and a rotating rod 1 301 is mounted on the output end of the motor 3, and the rotating rod 1 301 is rotatably arranged on the inner side end of the straight groove 201, and a water drop plate 1 302 is fixedly connected to the outer end of the rotating rod 1 301, and a rotating rod 2 304 is rotatably arranged between the inner sides of the straight groove 201, and a water drop plate 2 305 is fixedly connected to the outer end of the rotating rod 2 304, and the bottom ends of the water drop plate 1 302 and the bottom ends of the water drop plate 2 305 are both arc-shaped, and when the arc ends face the lower pressure plate 5, the water drop plate 1 302 and the water drop plate 2 305 do not contact the lower pressure plate 5, and the water drop plate 1 302 The top and the top of the water drop plate 2 305 are both protrusions. When one end of the protrusion faces the top of the lower pressure plate 5, as the water drop plate 1 302 and the water drop plate 2 305 are rotated, they will press the lower pressure plate 5 to move downward. A transmission assembly is provided between the outer end of the rotating rod 1 301 and the outer end of the rotating rod 2 304. The transmission assembly includes a sprocket 1 303 and a sprocket 2 306. The sprocket 1 303 is fixedly connected to the outer end of the rotating rod 1 301, and the sprocket 2 306 is fixedly connected to the outer end of the rotating rod 2 304. A chain 307 is sleeved between the outer end of the sprocket 1 303 and the outer end of the sprocket 2 306, which can facilitate the rotating rod 1 301 and the rotating rod 2 304 to rotate in the same direction.

[0031] During implementation: by starting the motor 3 to drive the rotating rod 1 301 to rotate, since a chain 307 is sleeved between the outer end of the sprocket wheel 1 303 and the outer end of the sprocket wheel 2 306, when the rotating rod 1 301 rotates, it will drive the rotating rod 2 304 to rotate in the same direction. At this time, when the protruding end of the side end of the water drop plate 1 302 and the water drop plate 2 305 rotates to the top of the lower pressure plate 5, it will move downward against the lower pressure plate 5, and at the same time, it will also drive the pressure plate 601 and the bending plate 502 to move downward together. The top of the bending groove 101 is formed, and when the pressing plate 601 moves downward, the roller 602 will press against the top of the metal product, thereby limiting the top of the metal product. At this time, the cylinder 501 is started to drive the bending plate 502 to move downward, so that the metal product can be bent in accordance with the bending groove 101. During the bending process, the pressing plate 601 and the roller 602 can prevent the bending plate 502 from displacing and tilting the metal product when the metal product is pressed downward, thereby preventing the metal product from being bent with varying quality, thereby reducing production costs.

[0032] When the protruding end of the water drop plate 1 302 and the water drop plate 2 305 rotates and one end of the arc faces the top of the lower pressure plate 5, the water drop plate 1 302 and the water drop plate 2 305 no longer press the lower pressure plate 5, and the spring 402 will rebound against the lower pressure plate 5. At this time, the lower pressure plate 5 moves up, and the cylinder 501 drives the bending plate 502 to reset, so as to facilitate the next bending process of multiple groups of metal products.
