[0029] As shown in Figure 2 , Figure 4 , the surface of the moving rod 1103 is installed with two fixed rods 1105, the surface of the two fixed rods 1105 is installed with a baffle 1106, and the baffle 1106 is in contact with the two positioning plates 5, in this embodiment, through the setting of the baffle 1106, the limiting effect on the sheet metal forging during the die bending process can be achieved, avoiding the deviation of the sheet metal forging, when the moving rod 1103 moves horizontally, the two fixed rods 1105 and the baffle 1106 move.

[0030] As shown in Figures 1-3 , Figure 5As shown in the figure, the collection warning mechanism 13 comprises a collection box 1301 installed on the surface of the guide plate 12, a spring 1302 is installed inside the collection box 1301, a support plate 1303 is arranged on the spring 1302, the support plate 1303 is slidingly installed on the inner wall of the collection box 1301, a sliding slot 1305 is penetrated through the front side of the collection box 1301, a long rod 1304 is slidingly installed on the inner wall of the sliding slot 1305, the long rod 1304 is installed on the surface of the support plate 1303, an installation plate 1306 is installed on the front side of the collection box 1301, a control switch 1307 is installed on the top of the installation plate 1306, the control switch 1307 corresponds to the long rod 1304, an alarm 1308 is installed on the top of the installation plate 1306, and the control switch 1307 is a press switch in this embodiment. The bent sheet metal forging is guided by the guide plate 12 to slide on the top of the support plate 1303, when the bent sheet metal forging reaches a certain value, it will drive the support plate 1303 and the long rod 1304 to move downward under the action of its weight, the support plate 1303 compresses the spring 1302, and the long rod 1304 is pressed on the control switch 1307 to trigger the alarm 1308 to remind the workers and transport the bent sheet metal forging.

[0031] As shown in the figure, Figure 5 The number of springs 1302 is four and is distributed in a rectangular shape, and in this embodiment, due to the number and orientation distribution of the springs 1302, the force is evenly distributed.

[0032] In summary, in use, the sheet metal forgings are stacked on the two L-shaped plates 9, and under the action of the positioning frame 10, they are aligned with the two positioning plates 5, and the first sheet metal forging is pushed to the space between the two positioning plates 5 and on the two cylinders 4, and then the pushing mechanism 11 is reset by the control console 14 and is in contact with the two positioning plates 5, which can avoid the offset of the sheet metal forgings during die bending. At this time, the cylinder 7 is started by the control console 14, which drives the bending upper die 8 to move downward, and the first sheet metal forging is die-bent. In the process of die-bending, the first sheet metal forging can drive the two cylinders 4 to rotate on the two connecting frames 3. Due to the action of the two cylinders 4, scratches on the sheet metal forgings can be avoided. When the die-bending is completed, the second sheet metal forging is pushed by the pushing mechanism 11, which will push the first sheet metal forging. Under the action of the guide plate 12, the first sheet metal forging slides into the collection warning mechanism 13 for collection. The above steps are continuously processed. When the collection warning mechanism 13 collects a certain weight, an alarm is triggered to remind the staff to transfer the bent sheet metal forgings. The automatic feeding and discharging of the sheet metal forgings and the warning collection of the bent sheet metal forgings are realized, which improves the processing efficiency, is simple to operate, and has strong practicality. The motor 1107 is started, which drives the screw 1102 to rotate, so that the moving rod 1103 moves horizontally, thereby adjusting the position of the moving rod 1103. When the moving rod 1103 moves horizontally, the pushing plate 1104 moves with it, which pushes the sheet metal forgings in the positioning frame 10 for feeding, and blocks the sheet metal forgings above the pushing plate 1104 in the positioning frame 10, avoiding the influence of the falling of other sheet metal forgings on the resetting of the pushing plate 1104. The setting of the baffle 1106 can limit the position of the sheet metal forgings during die-bending, avoiding the offset of the sheet metal forgings. When the moving rod 1103 moves horizontally, the two fixed rods 1105 and the baffle 1106 move with it. It is explained that the control switch 1307 is a press switch. The bent sheet metal forgings are guided by the guide plate 12 to slide on the top of the support plate 1303. When the bent sheet metal forgings reach a certain value, they will drive the support plate 1303 and the long rod 1304 to move downward under the action of their weight. The support plate 1303 compresses the spring 1302, and the long rod 1304 is pressed on the control switch 1307 to trigger the alarm 1308 to remind the staff to transfer the bent sheet metal forgings. Due to the number and position distribution of the springs 1302, the force is evenly distributed.

It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only the principles of the present application.
