The invention discloses a multifunctional drawing machine which comprises a rolling mechanism and a wire drawing machine on the left side of the rolling mechanism, wherein an automatic spiral bar winding machine is arranged on the right side of the wire drawing machine; a spiral bar diameter turning wheel is arranged at the outlet end of the automatic spiral bar winding machine; a screw pitch variable-diameter block is closely fixed on the lower side of the spiral bar diameter turning wheel; an oxidation layer removal device is arranged at the inlet end of the left side of the wire drawing machine. The multifunctional drawing machine is novel in structure design, can be used for directly removing an oxidation layer through a straightening wheel, and is convenient for wire drawing; the diameters are uniform after wire drawing, and the wound spiral bars are uniform in size and convenient to control; a forming plate with a guide effect is cooperatively used with the spiral bar diameter turning wheel, so that the diameters of the spiral bars can be adjusted at will; the screw pitch of the spiral bars can be casually adjusted by adjusting the screw pitch variable-diameter block.
