The Square Spiral Forming Machine forms 6-inch to 30-inch continuous square spirals from wire up to 3/8 inches in diameter. The machine is powered by a 10 hp electric motor coupled to a variable displacement hydraulic pump. The pump displacement is variable for precise speed control without buildup of heat. The forming head jog and reverse functions are incorporated into push-button controls. The forming head speed is continuously variable from 10 to 45 rpm. The predetermining electronic counter can be preset for a given number of turns per coil. The forming machine stops automatically after the preset number of turns is formed to eliminate manually counting back each time a coil is cut off. The counter keeps track of the batch count as well. The forming head stops automatically when the guard is raised. The different-sized heads can be accommodated by moving the follower head carriage assembly toward or away from the forming head. The forming heads are mounted with split taper bushings for easy change-out.
Setup time is minimal due to quick-release cam levers incorporated into the adjustments throughout the machine. An external air supply capable of 120 psi at very low volume is required to charge the air cylinder, which acts as a spring on the follower head carriage.
