[0002] The controllable pendulum die is a special tool for metal processing, mainly used for stamping or bending metal workpieces. The die is designed with a controllable pendulum, which can adjust its position or angle to accurately control the speed and degree of metal rebound after bending, so as to achieve precise control of the workpiece shape. This die is widely used in fields that require high-precision bending or shape control, such as the automotive industry and electronic product manufacturing. By adjusting the pendulum, the operator can fine-tune and optimize the workpiece shape, improve product quality and production efficiency.
