Power press with a fixed barrier guard

A press, or a machine press is a tool used to work metal (typically steel) by changing its shape and internal structure.

A modern hammer is directly descended from ancient hand tools A tool is a device that provides a mechanical or mental advantage in accomplishing a task. ... Hot metal work from a blacksmith In chemistry, a metal (Greek: Metallon) is an element that readily forms ions (cations) and has metallic bonds, and metals are sometimes described as a lattice of positive ions (cations) in a cloud of electrons. ... Jump to: navigation, search The old steel cable of a colliery winding tower Steel is a metal alloy whose major component is iron, with carbon being the primary alloying material. ...


A forge press reforms the workpiece into a three dimensional object—not only changing its visible shape but also the internal stucture of the material. A stronger part results from this process than if the object was machined. A blacksmiths forge The forge or smithy is the workplace of a smith or a blacksmith. ... Jump to: navigation, search Dimension (from Latin measured out) is, in essence, the number of degrees of freedom available for movement in a space. ... A machine tool is a powered mechanical device, typically used to fabricate metal components of machines by the selective removal of metal. ...


Bending is a typical operation performed and occurs by a machine pressing, or applying direct pressure, to the material and forcing it to change shape. A press brake is a typical machine for this operation.


An easy to understand type of machine press is a set of rollers. Metal is fed into the rollers, which are turning to pull the material through. The space between the rollers is smaller than the unfinished metal, and thus the metal is made thinner and/or wider.


Another kind of press is a set of plates with a relief, or depth-based design, in them. The metal is placed between the plates, and the plates are pressed up against each other, deforming the metal in the desired fashion. This may be coining or embossing or forming. A punch press is used for forming holes. Coining is a form of precision stamping. ... A Punch Press is a machine that has a set of punches and dies, a male (punch) and female (die), which when pressed together put a hole into the material used that is the same geometry as the punch that is being used. ...


Progressive stamping is a manufacturing method that can encompass punching, coining, bending and several ways of modifying the metal, combined with an automatic feeding system. The feeding system pushes a coil of metal through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made per the requirements on the print. The final operation is a cutoff operation, whic separates the finished part from the carrying web. The carrying web, along with metal that is punched away in previous operations, is considered scrap metal. Jump to: navigation, search Progressive stamping is a manufacturing method that can encompass punching, coining, bending and several other ways of modifying metal, combined with an automatic feeding system. ...


Machine presses are used extensively around the world for shaping all kinds of metals to a desired shape. A typical toaster (for bread) has a metal case that has been bent and pressed into shape by a machine press.


History

Machine presses started as a hand-held hammer banging away at a piece of metal to shape it to the desired form. Later, larger hammers were constructed to press more metal at once, or to press thicker materials. Adding wind or steam power allowed for stronger presses. Most modern machine presses use a combination of electric motors and hydraulics to achieve the necessary pressure. A claw hammer A hammer is a tool meant to deliver blows to a target, causing it to move or deform. ... Hydraulics is a branch of science and engineering concerned with the use of liquids to perform mechanical tasks. ...
