Mechanical presses

Mechanical presses is crank or elbow-bar mechanism, cam, screw body driven metal forming machinery, used to pressure the material processing machine, by exerting strong pressure on stock that is deformed and fracture into parts. Smooth, high accuracy and good operating conditions, high productivity, easy to introduce mechanisation and automation, for work on the line, widely used in the Auto, shipbuilding and other industries mechanical presses. 1th of China's domestic press in December 1955 in Jinan second machine tool plant manufacturing success.

By crank-slider mechanism converts the rotary motion of the motor to the reciprocating motion of the slider, billet-machined metal forming machinery. Mechanical presses the action smooth, reliable, and widely used in stamping, extrusion, forging and powder metallurgy processes. Mechanical presses in the number accounted for more than half of the total number of all types of metal forming machinery. Mechanical presses, specifications nominal operating force (kn), said it is based on slider movement to about 10~15 mm from the stroke BDC (or starting from the bottom point approximately 15 ° ~30 ° crank angle α) as the base design of maximum work force
