Abstract
Although having a development history of over 200 years, researches and developments about press machines are still draw interest of modern mechanical engineering. This paper introduces a new press structure that utilizes a double crank mechanism to enhance productivity and efficiency for the stamping process. By adjusting the positions between the component links, the dynamic characteristic of the ram can be modified, optimizing the performance and improving operations of the system. The proposed design also allows for easy adjustments to adapt with different production requirements, such as changing forging and stamping speeds (fast and slow) to avoid the impact of springback properties in sheet metal. The kinematics of the structure have also been determined by mathematic equations, demonstrating significant improvements in the operation of the ram. Results from the research offers a promising solution to enhance production efficiency and enable the creation of simple yet capable mechanisms to perform complex operation.
