The press machine has the characteristics of wide application, high production efficiency and the like, and can be widely applied to processes of cutting, punching, blanking, bending, riveting, forming and the like. The metal is processed into parts by applying a strong pressure to the metal blank to cause plastic deformation and fracture of the metal. When the mechanical press works, a motor drives a large belt pulley (usually used as a flywheel) through a triangle belt, and a crank-slider mechanism is driven through a gear pair and a clutch, so that a slider and a male die move down linearly. After the forging and pressing work of the mechanical press is finished, the sliding block moves upwards, the clutch is automatically disengaged, and meanwhile, the automatic device on the crankshaft is switched on, so that the sliding block stops near a top dead center. When the concrete structure is broken in the process of pressure application, the pressure value displayed on the press machine is the ultimate pressure of the compressive strength, and the compressive strength of the concrete structure can be calculated according to the calculation formula of the compressive strength.
