[0025] The effect achieved by the entire Embodiment 1 is that when bending and processing an automotive door hinge, the second robotic arm 12 is activated. The second robotic arm 12 will grasp the workpiece in the storage box 13 and send it into the adjacent placement block 302. The motor 14 is synchronously activated, and the output end of the motor 14 rotates intermittently in the clockwise direction, causing the rotating rod 307 to drive the placement disk 301 to rotate synchronously. A plurality of mounting seats 304 are fixedly connected at equal intervals along the bottom edge thereof. The fixing frame 303 fixedly connected to the bottom of the mounting seat 304 will drive a plurality of rollers 305 to rotate on the top of the bearing disk 4. An annular chute 5 is formed on the top of the bearing disk 4, and a plurality of support rods 6 are fixedly connected at equal intervals on the top to support it.

During the stay, the hydraulic rod 7 is activated, and its telescopic end drives the pressing block 9 at the bottom of the mounting block 8 to press down, so that the automotive door hinge workpiece in the placement block 302 will be bent under the action of pressure. By using the intermittent rotation of the placement disk 301, a plurality of placement blocks 302 are successively and orderly driven to move under the mounting frame 2 for bending operations. The first robotic arm 10 grasps the bent hinge workpiece and sends it into the collection box 11 on one side of the frame 1, and the second robotic arm 12 grasps the workpiece in the storage box 13 on the other side of the frame 1 and sends it to the adjacent empty placement block 302, playing the role of automatic loading and unloading.

[0026] Embodiment 2, as Figures 1 - 5 shown, the output end of the motor 14 rotates through the inner bottom of the frame 1, and the output end of the motor 14 is fixedly connected to the bottom of the rotating rod 307. The inner surface of the bearing disk 4 is rotationally connected to the outer surface of the rotating rod 307. A reinforcing block 308 is fixedly connected to a position near the top of the outer surface of the rotating rod 307, and the top of the reinforcing block 308 is fixedly connected to the bottom of the placement disk 301.

[0027] The effect achieved by the entire Embodiment 2 is that during use, a reinforcing block 308 is fixedly connected to a position near the top of the outer surface of the rotating rod 307, and the top of the reinforcing block 308 is fixedly connected to the bottom of the placement disk 301, increasing the contact surface between the rotating rod 307 and the placement disk 301, making the placement disk 301 stable during rotation, and improving the stability of the automatic loading device for bending automotive door hinges.

[0028] Working principle: When in use, start the motor 14. The output end of the motor 14 rotates intermittently in the clockwise direction, causing the rotating rod 307 to drive the placing plate 301 to rotate synchronously. When the placing plate 301 rotates intermittently, start the second robotic arm 12. The second robotic arm 12 will grab the workpiece in the storage box 13 and send it into the adjacent placing block 302, so that multiple hinge workpieces will be sequentially placed into multiple placing blocks 302. At the same time, multiple placing blocks 302 fixedly arranged at the top thereof will sequentially stay briefly below the mounting frame 2. During the stay, start the hydraulic rod 7, and its telescopic end drives the pressing block 9 at the bottom of the mounting block 8 to press down, so that the automotive door hinge workpiece in the placing block 302 will be bent under the action of pressure. Under the action of multiple intermittent rotations of the placing plate 301, the workpieces in multiple placing blocks 302 will all rotate past one side of the first robotic arm 10 and the second robotic arm 12. By using the intermittent rotation of the placing plate 301, multiple placing blocks 302 are sequentially and orderly driven to move under the mounting frame 2 for bending operations. The first robotic arm 10 grabs the bent hinge workpiece and sends it into the collection box 11 on one side of the frame 1, and the second robotic arm 12 grabs the workpiece in the storage box 13 on the other side of the frame 1 and sends it to the adjacent empty placing block 302, playing the role of automatic loading and unloading. Thus, when manual feeding by personnel is avoided, in case of accidental touch operation by personnel, it is easy to cause harm to the personnel under the stamping device, improving the safety of the automatic loading device for bending automotive door hinges.
