[0002] A hinge, also known as a joint, is a mechanical component used to connect two or more fixed objects, allowing them to rotate relative to each other within a certain range. The design of a hinge allows the connected parts to rotate or translate flexibly while maintaining the connection, thus enabling various opening and closing actions. A rolling mechanism is typically used to roll up bent hinges.

The driving device 7 is a hydraulic cylinder, and its output end is connected to the front side of the connection point between the moving plate 3 and the connecting block 4. The limiting plate 6 is located above the rear end of the moving plate 3, so that the bottom surface of the limiting plate 6 can fit against the top surface of the rear end of the moving plate 3. During operation, the bent workpiece is placed on the rolling die core 5. After placement, the driving device 7 drives the moving plate 3 and the connecting block 4 to move backward, thereby...

In this application, through the fixed base 1, mounting plate 2, moving plate 3, connecting block 4, rolling die core 5, limiting plate 6, driving device 7 and mounting groove 8, when the workpiece is formed under the action of the rolling die core 5 and the limiting plate 6, because the top surface of the rear end of the moving plate 3 is always in contact with the bottom surface of the limiting plate 6, it can prevent the workpiece from deforming towards the hollow area and causing the workpiece to not be fully formed, which is beneficial to improving the rolling forming quality. Furthermore, installing the rolling die core 5 in the mounting groove 8 at the connection between the rear end of the connecting block 4 and the moving plate 3 is beneficial to improving the installation stability of the rolling die core 5, making it less prone to deviation and displacement, and ensuring the rolling forming quality.
