The invention relates to a shearing machine for transversally dividing especially a heavy steel plate, said shearing machine comprising an upper blade (3) which carries out a rolling cutting movement by means of an eccentric drive (8) and is held in a blade carrier (1), and a lower blade (4) which is arranged in the frame of the shearing machine (2) in a fixed manner, the upper blade carrier (1) being displaceably connected to a stand (6) of the shearing machine frame (2) by means of an articulated guiding element (5). A device for the clocked advance of a pre-determinable length of the steel plate is associated with the shearing machine, especially in the form of at least one driving element. The aim of the invention is to improve the stability of the shearing machine and thus the quality of the cut. To this end, the shearing machine is arranged between lateral stands (6, 6′) of the shearing machine frame (2) which is closed by an upper traverse (7) and a lower traverse (7′). The eccentric drive (8, 8′) of the upper blade (3) is arranged in the upper region of said frame, and bearings (10, 10′) and driving bodies (11) of lower driving rolls (12, 12′) are arranged in the lower region of said frame, in addition to a lower blade table (9) which is anchored between the stands (6, 6′).
Shear for cutting especially heavy steel plate to length with an upper blade (3), which carries out a rolling cutting movement by means of an eccentric drive (8) and is held in a blade holder (1), and with a lower blade (4), which is mounted in a stationary way in the shear frame (2), wherein the upper blade holder (1) is movably connected by an articulated guide element (5) with a shear frame column (6) present on the shear, and a device for the timed advance of predeterminable lengths of the steel plate, especially in the form of at least one driver, is assigned to the shear, wherein the shear is arranged between lateral columns (6, 6′) of a shear frame (2) with a closed construction with one upper cross-frame (7) and one lower cross-frame (7′), such that the eccentric drives (8, 8′) of the upper blade (3) are installed in the upper region of the shear frame (2), and in the lower region of the shear frame (2), bearings (10, 10′) and drive mechanisms (11) of the lower driver rolls (12, 12′) are installed, and a lower blade table (9) is rigidly mounted between the columns (6, 6′), and that the lower blade table (9) is assigned a lower gearbox (15), which has a central bearing (16) in addition to the bearings (10, 10′) of the lower driver rolls (12, 12′).
