High Force Servo Motor Driven Spot Welding Head - 73 Head - 1

Servo Motor Driven Weld Head • Programmable speed and positions • Controlled servo motor actuation eliminates overforce • Force range 15 lbs to 110 lbs. • Durable and robust head design • Displacement and force options • Remote control I/O and PC communication 73 Opposed Weld Head Designed for use in automation or benchtop welding, Miyachi Unitek’s Model 73 and Model 73-Z weld heads offer fast, repeatable electrode motion control for a wide range of resistance welding applications. The Model 73 weld head is an easyto-program, state-of-the-art servo motor controller that allows precise programming of electrode position and speed for up to 31 different weld schedules. The 73-Z pincer weld head has self centering electrode clamping and floating mechanism to ensure the part is centered between the electrodes every time. 73-Z, Pincer Weld Head TYPICAL APPLICATIONS KEY FEATURES • Individual speed control for “stroke to search” and “search to weld” Good for automation – increases flexibility and throughput • Machine builder module – A module option without a lower electrode or extrusion provides convenient machine mounting • 31 schedules – Write and save up to 31 motion schedules • Fast follow-up – Less weld splash, more consistent welds • Overforce protection – Ensures concise, repeatable force, less weld splash, reduced part deformation • Force independent of part height – Constant applied force ensures weld repeatability • Easy programming – Fast, efficient schedule adjustment • “Soft-touch” part clamping – Minimizes impact force – allows verification of part alignment prior to welding Terminal connections for sensors Magnet wire to tang termination Joining of stamped sub-assemblies
