Device for reciprocating a band saw perpendicular to its longitudinal axis

摘要

Actuating device (35) for a toothed-band cutting blade (4) of a sawing machine (1) is proposed; the cutting blade (4) is driven with a longitudinal translatory movement relative to a workpiece (9) to be cut; a blade section (14) lies in a predefined cutting plane and has a first end portion (114) on the entry side of the workpiece (9) and a second end portion (214) on the exit side of the workpiece (9); the actuating device (35) comprises a thrusting element (37) designed to engage with the second end portion (214) of the blade section (14) so as to impart to the second end portion (214) a movement substantially perpendicular to said longitudinal translatory movement and having a predefined frequency. <IMAGE>
