Do you know the common faults and repair methods of press?

Press (including punch and hydraulic press) is a kind of universal press with exquisite structure. With the characteristics of wide use and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming. Automobile parts manufacturers make parts by exerting strong pressure on metal blanks to cause plastic deformation and fracture of metal. When the mechanical press works, the motor drives the large pulley (usually also used as flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and the clutch, so that the slider and the punch go down in a straight line. After the mechanical press completes the forging work, the slider travels upward, the clutch is automatically disengaged, and the automatic device on the crank shaft is connected to stop the slider near the top dead center.
