Abstract

An improved pressing machine for forming a work (21) being progressively or sequentially fed along a coil line, having a press assembly (1) that comprises a plurality of modular press units (1.sub.1, 1.sub.2, 1.sub.3, . . . ) connected from one to another in a direction in which the work (21) is progressively fed. Each of the press units (1.sub.1, 1.sub.2, 1.sub.3, . . . ) includes a C-form frame (2), a slide drive mechanism (6) disposed in an upper part of the C-form frame (2) and having in its drive source (7) a servo motor means operable under NC, and a slide (5) adapted to be driven by the slide drive mechanism to move in a given movement pattern. The press units (1.sub.1, 1.sub.2, 1.sub.3, . . . ) having their respective slides (5), at least some of which have at least one slide adapter plate (19) attached thereto, the at least one slide adapter plate extending across those at least some of the slides as a whole. With the pressing machine so constructed, mounting a die that is long in length to the slide adapter plate (19) enables forming a long or elongate work (21). Also, the pressing machine can be provided with a number of working stations in a direction of the coil line, thus enabling a multiple process step forming operation.
