    Forging roll for pre-forming round and square material

    Lasco see significant material savings, enhanced workpiece surfaces through de-scaling and an improvement in die-cutting times during the subsequent forging process as the key advantages of their forging roll.

    The RCW forging roll from Lasco is designed for pre-forming round and square material.

    In the experience of Lasco, the material cost element of unit costs for die forgings is 30 to 50 percent. For this reason alone, optimal pre-forming is seen as essential to reduce these unit costs. The goal, according to the company, is to achieve maximum closeness to the final form with the help of material distribution at an early stage of production. Good initial distribution of material reduces material flow later in the forging die, increasing the working life of the die. The forging roll presented has been designed for the pre-forming of round and square material. As is explained, in contrast to cross-wedge rolling, the blank is fed radially into the rollers by a manipulator and pre-formed in individual sectors (passes). The completed blank is subsequently laid on a conveyor and fed to the main forming machine. Advantages highlighted by the manufacturers include a considerable saving of material, an enhanced workpiece surface thanks to de-scaling, and an improved die life in the subsequent forging due to the de-scaling and the reduction of material flow in the die.
