Structure description of screw press
The screw and nut are used as the transmission mechanism, and the forward and reverse rotary motion of the flywheel is converted into a forging and pressing machine that reciprocates up and down the slider by a screw drive. During operation, the motor accelerates the flywheel to save energy, while pushing the slider downwards through the screw and nut. When the slider contacts the workpiece, the flywheel is forced to decelerate to a complete stop, the stored rotational kinetic energy is converted into impact energy, and the workpiece is deformed by the slider. After the blow is over, the motor reverses the flywheel, causing the slider to rise and return to its original position. Screw press specifications are expressed in terms of nominal working force.
The screw press is usually driven by the motor to drive the flywheel rim through the friction disk to rotate the flywheel, so this press is also called a friction press. China's largest friction press is 25 meganewtons. Larger screw presses use a hydraulic system to drive the flywheel, known as a hydraulic screw press, with a maximum specification of 125 meganewtons. Later, there appeared an electric screw press that directly driven the flywheel with an electric motor. It has a compact structure and a small number of transmission links. Due to frequent commutation, it requires a relatively high degree of control electronics and requires a special motor.
