Stamping presses transform sheet metal into functional products by applying the force of a moving ram to tooling located within the press. Stamping’s primary advantage is the ability to transform two-dimensional sheet metal stock into three-dimensional finished components at a relatively high rate of speed with minimum operator intervention.
Part of the Fundamental Manufacturing Processes Video Seriesthis program provides a broad understanding of stamping presses, and includes segments on: mechanical presses, hydraulic presses, press controls, and press feeding.
The mechanical presses segment outlines the advantages/disadvantages and the similarities/differences between the two most common types of presses, the gap-frame press and the straightside press. Defined and detailed are the various press components, including the crown, columns, gibs, bed , bolster, flywheel, gears, clutch, crankshaft, pitman, connection, slide/ram, counterbalance, and brake. Drive arrangements, such as direct drive, single gear reduction, double gear reduction, and eccentric geared presses are also illustrated.
The hydraulic presses segment explains the major differences between hydraulic presses and mechanical presses and highlights the advantages of hydraulic systems and press selection factors.
The press controls segment features the range of controls — electro-mechanical, pneumatic, hydraulic, electronic, and others —andnbsp;used to safely control press operations. Computer numerical control (CNC) systems, programmable logic controllersandnbsp;(PLC), and self-checking/diagnostic features are also detailed.
The press feeding segment covers coil stock and blank feeding methods, as well as coil line components. These components include payoff reels, cradles, stock straightening/leveling, slide feeds, roll feeds, gripper feeds, and scrap processing.
