ABSTRACT:
A forming machine has a shearing device for shearing a bar. This shearing device comprises a fixed blade, with a passage for feeding through the bar to be sheared, and a shearing part which can be moved forward and backward parallel to the fixed blade. The shearing part comprises a first shearing blade, with which a bar section projecting from the fixed blade can be sheared in a forward movement of the shearing part, and a second shearing blade, with which a bar section projecting from the fixed blade can be sheared in a backward movement of the shearing part. In addition, the forming machine has a disposal point, to which the second shearing blade transports, as scrap pieces, all the bar sections sheared by it. Due to scrap pieces being sheared solely by means of the second shearing blade, empty places in the forming stations and the associated disadvantages can be avoided.
