The bed or table of a gap-frame press, such as a horn press, which is bolted to the vertical front surface of the press. It is supported and adjusted (up and down) by means of a screw or screws usually operated by hand. This term also refers to the bed of a large straight-side press mounted and guided in the press frame and provided with a suitable mechanism, usually power operated, for varying the die space shut height. Adjustable-bed presses are also referred to as knee-type presses.

The capability of varying the length of a stroke on a press.

The distance that a press slide position can be altered to change the shutheight of the die space. The adjustment may be by hand or by power mechanism.

A process of aging that increases hardness and strength and ordinarily decreases ductility. Age hardening usually follows rapid cooling or cold working.

An alloy steel that is hardened by cooling in air from a temperature higher than the transformation range. Also called self-hardening steel.

A substance that has metallic properties and is composed of two or more chemical elements of which at least one is a metal.

The form of iron that is stable below 910C, (1,970F) and characterized by a body-centered cubic crystal structure.

A heat treatment designed to effect: softening of a cold worked structure by recrystallization, or grain growth, or both; softening of an age hardened alloy by causing a nearly complete precipitation of the second phase in relatively coarse form; softening of certain age hardenable alloys by dissolving the second phase and cooling rapidly enough to obtain a supersaturated solution (this usage is generally applied to nickel-base and copper-base alloys the treatment should be called more precisely a solution heat treatment); relief of residual stress and change in properties induced during the forming process.

A trade name for a patented heat treating process that consists of quenching a ferrous alloy from a temperature above the transformation range in a medium with a heat abstraction rate sufficiently high to prevent the formation of high-temperature transformation products, and maintaining the alloy, until transformation is complete, at a temperature below that of pearlite formation and above that of martensite formation.

A solid solution in which gamma iron is the solvent. Characterized by a face-centered cubic crystal structure.

A machine-generated signal for stopping the action of a press, usually after a complete cycle, by disengaging the clutch mechanism and engaging the brake mechanism.
