The invention discloses a parallel wire roller pulling combined forming technology for manufacturing a parallel wire with a straight edge round angle. The parallel wire roller pulling composite forming technology comprises the steps of carrying out rolling on a round steel wire through a two-connecting type two-roller die, forming an initiative long side of the parallel wire in an extension direction which is parallel to the round steel wire in a rolling manner, reforming an initiative wide side of the parallel wire in the direction which is perpendicular to the long side in a rolling manner, and finishing rolling of the round steel wire in four directions of a rectangle; and carrying out rolling through a fixed type four roller die so as to form an initiative parallel wire of a straight side, wherein the initiative parallel wire with a regular straight-flange fillet is formed by drawing with a rectangle fixed type drawing die the cross section of which is a straight-flange fillet. The invention also relates production equipment of the parallel wire roller pulling composite forming technology. The parallel wire roller pulling composite forming technology provided by the invention has the advantages that the condition that four round angle parts of a steel wire are seriously damaged is overcome when the rectangle is drawn, a falling angle is formed, the deficiency of the requirement of the size of the product cannot be met, and a better effect is obtained.
