Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.
A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1] The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to their mechanism: hydraulic, mechanical, pneumatic;
Press fit is achieved with presses that can press the parts together with very large amounts of force. The presses are generally hydraulic, although small hand-operated presses (such as arbor presses) may operate by means of the mechanical advantage supplied by a jackscrew or by a gear reduction driving a rack and pinion. The amount of force ...
The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
Liner bushings, sometimes called master bushings, are permanently installed into the jig and accept liners that can easily be replaced. Press-fit wearing bushings are used in short run applications or in applications where the tolerance on a hole location is so tight that it cannot facilitate the use of a liner bushing. [3]
A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
Surrounding the sleeve is the bushing, fixed in the chock, which carries the radial load. The precision sleeve rotating in the bushing on an unbroken film of oil provides a bearing with a low coefficient of friction, low power consumption, high load capacity, high stiffness, and freedom from wear and fatigue.
Press fittings with appropriate and region-specific certification may be used for gas lines. Stainless steel and carbon steel press fittings can withstand up to 16 bars of pressure. A disadvantage of press fittings is the dead space between the pipe and the fitting, which can possibly rule out use for beverage and food applications.
