Multifunctional CNC spring forming machine

Abstract

The invention relates to spring forming devices, in particular to a multifunctional CNC spring forming machine. The multifunctional CNC spring forming machine comprises a wire feeding and transferring drive mechanism, a straightening mechanism, a curl forming mechanism and a cut-off mechanism. The wire feeding and transferring drive mechanism comprises a wire spool and a wire feeding device. The wire feeding device comprises guide rails, a sliding table, a power unit, a fixed base, clamping units, wire supporting tables and a wire guide table. The power unit controls the sliding table to slide relatively on the guide rails, and the fixed base is fixed on the sliding table. The number of the clamping units is at least three, the ends of the clamping units are fixed on the fixed base in parallel, and the wire supporting tables are respectively arranged between the clamping units. The wire guide table is arranged between the wire feeding device and the straightening mechanism. Each clamping unit comprises a hydraulic oil cylinder, a chuck and a clamping base, wherein the chuck is arranged at the output end of the hydraulic oil cylinder, and the clamping base is arranged on the other side, opposite to the chuck, of the sliding table and is matched with the chuck. The multifunctional CNC spring forming machine is high in clamping force to metal wires and accurate in wire feeding position.
