Abstract

The present invention relates to a spiral cramp iron bender, which mainly comprises a bender body (5) and a transmission shaft (6) borne thereon. The bender body comprises a power roller (53), a driven roller (54), and a transporter (55). The transmission shaft comprises a connection end to connect to a screw shaft (7), and the screw shaft comprises a plurality of groove spires in predetermined thread pitches on the surface thereof. The transmission shaft (6) rolls by power driving, and so rolls the screw shaft (7). As cramp iron is transported to the bender body by the transporter, the power roller (53) guides cramp iron into the groove spire of the screw shaft. The power roller and the driven roller driving guide cramp iron forward rolling around the rolling screw shaft and along one groove spire to the next groove spire round and round, and finally cramp iron is automatically bent to a spiral cramp iron with the predetermined thread pitch.
