Sewing machine needle bar high frequency induction hardening machine toolSewing machine needle bar high frequency high frequency induction hardening machine tool is a fully automatic induction hardening machine tool. And it can be supported with 30-60kw high-frequency power. And it can get on continuous feeding for work pieces with thin rod. While rotating, it goes through the inductor and spray ring. Induction heating is controlled by the phototransistor, and the work piece can be full-length or partial quenching.It can be quenched the maximum work piece diameter of 15mm and length of 110-300mm. Guide wheel speed is divided into six with 85-130r per minute and the size of 200mm × 75mm × 75mm. Motor is transmitted to speed change device through pulley, and it starts to change speed by pulley after going through the worm wheel reducer, which will receive six kinds of speed.The feed rate of work piece quenching depends on the guide wheel speed, and the diameter of the guide wheel and the angle the guide wheel is adjusted. This machine tool is provided with a lower rack, suitable for mass production.
