stamping-press

Century Dictionary and Cyclopedia

1. n. In sheetmetal work, a power-machine for making hollow ware, as pans, bowls, kitchen-utensils, etc. Machines of this class are a development of the earlier stamping-machines, the direct blow or stamp having been replaced in many instances by a continuous pressure. The essential features of the machine are two dies brought one over the other by a direct blow or by pressure. Where a continuous pressure is used by the employment of a screw, cam, toggle-joint, or eccentric, forcing one die slowly upon the other, the sheet of metal is pressed and stretched into shape. The dies are often compound—one part cutting out the blank from the sheet and another part compressing it gradually into shape—or so arranged that one part takes the blank, and holds it firmly by the edges, while a central part stretches it to the required shape. In some forms of these machines a series of dies are used successively, the blanks being pressed in part, then annealed and re-pressed until the final shape is secured. Also called stamping-machine.
2. n. A small hand-press or seal-press used by public officials and others for impressing stamps upon or affixing them to documents, either in obedience to legal requirement or as a matter of convenience or custom. Compare seal-press.
3. n. Same as blocking-press. See also armingpress.
