Specify a Press Size required for sheet metal work.
Specification of Press Size:
Shut Height- The space available between the press bed or bolster and the slide or ram is called the shut height. It is always measured with the press shut or at bottom dead center. It may be specified as the vertical space between the ram and either the top of the bed or bolster
Bed and Bolster- The bolster adds stiffness to the press bed and has tapped holes, or preferably T-slots, to permit the die to be fastened in the press. T-slots permit dies to be changed quickly and fastened in the press more securely than tapped holes.
Press Frame Members-The strength of the parts that make up the framework or housing of presses determines the force capacity of the machine. Heavy frames limit deflection and help damp harmful vibrations.
Brake-The friction mechanism used to stop or control the motion of a press, feed or other mechanism. Brake stopping time must be monitored in MS / milliseconds to assure that the press slide stops within a safe acceptable limit.
Clutch -A coupling used to connect or disconnect a driving machine-member, such as a shaft or wheel, to or from a driven machine-member, such as another wheel or shaft. The engaging or disengaging can be done by a hand operated controlling device operated manually or automatically.
Flywheel -A wheel used on an engine or machine with a rotation energy or inertia able to prevent excessive or sudden changes in speed. In modern mechanical presses the flywheel is usually driven by multiple belts from the main motor pulley to the flywheel. A clutch is mounted on or within the flywheel which, when engaged starts slide movement
Stroke-The reciprocating motion of a press slide, usually specified as the number of inches between the terminal points of the motion. Stroke length relates to speed ranges, the longer the stroke the slower the press speed range.
