TECHNICAL PARAMETERS Crank presses are mechanical two-point drawing presses with a nominal forming force of 2.5 MN, with frames of "O" shape (LKT) or "C" shape (LDC) with large tables and rams. Presses can be equipped with pneumatic or hydraulic tensile holding means.
hydraulic and mechanical pressesThe most powerful mechanical presses in modern manufacturing industry will have a press capacity of about 12,000 tons, (24,000,000 lbs). Crank Press . The crank press uses a crank link attached to a drive shaft. The crank link rotates with the drive shaft and is attached to a connecting rod by a rotational joint.
fundamentals of mechanical-press design - metalforming magazineThe force-vs.-crank angle curve indicates that the press in question may be subjected to a nominal load of 1000 kN between 30 deg. before BDC and at BDC, while at 90 deg. before BDC a slide load of only FN0/2 = 500 kN is permissible.

sawing energy in mechanical crank press drives - jan hlavac, jiri ...This is the most frequently used drive system for crank presses due to its simple design. Of all the flywheel drives its drive is the stiffest from the motor to the crankshaft, it has the lowest energy losses in coupling (there is only a belt coupling from the motor to the flywheel) and is the cheapest thanks to its low technological manufacturing requirements.
mechanical presses overview - pressmachPressmach one-point straight side presses (a.k.a. single crank presses) feature precise slide guiding and frames designed to handle higher tonnage without the risk of angular deflection or yawning.
24 eccentric and crank presses - springerEccentric and crank presses are controlled by the ram path. 24.1 Types of these presses These presses are categorised according to the design of the press frame (Figure 24.1) into: a) gap-frame presses b) open-back presses c) straight-side presses. Figure 24.1Press frames. a) gap frame, b) open-back frame, c) straight-side frame
eccentric presses with link drive device - mossini presseProducts Mechanical presses It is a special mechanism that integrates the traditional rod-crank system for transmitting motion to the slide. The device consists mainly of molten steel levers, complete with special bronze bearings and hardened pins 39NiCrMo3. Its usage offers considerable advantages:
