We offer electrical dc upsetting machines. • heating transformer works on 3 phase 400vac. • dc heating. • no skin effect as in ac heating, thereby providing uniform heating across the cross section of the job. • heating power infinitely variable by thyristor. • auto indexing of anvil after every upsetting cycle. • bulb temperature measured by optical infrared pyrometer and controlled by hydraulic servo valve. • bulb shape is controlled without wrinkles by anvil speed control using another servo valve. • maximum upsetting force – 7000kgf.
