Description

Open type fixed table press machine

Technical Field

Background

The press (including a punch press and a hydraulic press) is a universal press with an exquisite structure. 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 to process parts by applying strong pressure on metal blanks to enable metal to generate plastic deformation and fracture. 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. Open presses, generally referred to as crank presses, use mechanically driven forging machinery to impart motion and energy from an electric motor to a working mechanism through a drive train to impart a desired shape to a blank.
