Principle of SINGLE-CRANK PRECISION PRESS
SINGLE-CRANK PRECISION PRESS is a compact universal press. With a wide range of uses and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. Machined into parts by applying strong pressure to a metal blank to plastically deform and fracture the metal. When the mechanical press is working, the motor drives the large pulley (usually doubles as a 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 straight down. SINGLE-CRANK PRECISION PRESS After the forging work is completed, the slider travels upward, the clutch is automatically disengaged, and the automatic on the crankshaft is turned on, making the slider stop near the top dead center.
SINGLE-CRANK PRECISION PRESS is driven by the motor through the transmission mechanism to apply process force to the workpiece. The transmission mechanism is a reduction mechanism of belt transmission and gear transmission; the working mechanism is divided into a screw mechanism, a crank connecting rod mechanism and a hydraulic cylinder.
SINGLE-CRANK PRECISION PRESS is divided into three categories: screw press, crank press and hydraulic press. Crank presses are also known as mechanical presses.
SINGLE-CRANK PRECISION PRESS has no fixed bottom dead center. For larger die forgings, it can be formed by multiple blows, and can perform single, continuous and inching. The striking force is related to the deformation of the workpiece. When the deformation is large, the striking force is small, and when the deformation is small (such as cold shock), the striking force is large. In these respects, it is similar to a forging hammer. However, its striking force is closed through the frame, so the work is stable, the vibration is much smaller than that of the forging hammer, and a large foundation is not required.
The lower part of SINGLE-CRANK PRECISION PRESS is equipped with forging ejector. The press has the functions of various forging machines such as die forging hammer and mechanical press. It has strong versatility and can be used for die forging, blanking, deep drawing and other processes. In addition, the screw press is simple in structure and easy to manufacture, so it is widely used.
