Shock absorber rod induction quenching and tempering automatic machine toolQuenching and tempering progresses are carried out on a single machine tool. Quenching is used the power with 100KW and 90-150KHz; Tempering heating uses the power of 50KW and 4-10KHz. Quenching method is scanning, which can be a single segment or fragment heating. Shock absorber rod is fed by the stick with automatic loading and unloading, and quenching and tempering process can be automatically detected. Production capacity is as an example of connecting rod with a diameter of 20mm, length of 400mm and the production rate of 54s per piece. Technical parameters: Quenching with 100KW, 100 KHz power supply; Tempering heating using 50KW, 15KHz power; Scanning speed of 3-8m / min.
