Auto Parts High Frequency Sprocket hob Induction Hardening Quenching Equipment
1. Technical advantage of high frequency quenching machine:
Gears need quenching heat treatment to improve their own hardness,
wear resistance and practical life. The quenching of gears is
mostly carried out by high-frequency induction heating equipment,
but quenching defects will occur due to various factors during the
quenching process.
The surface of the double gear and the planetary bevel gear is
quenched by high-frequency induction heating equipment. The
workpiece material is 40Cr steel. The hardness of the
high-frequency induction heating quenching is required to be
45-55HRC, and the depth of the hardened layer is 2.5-3.5mm, using
0.5% ( mass fraction) PVA quenching medium quenching and cooling.
In production, it is found that there are many factors affecting
gear distortion, which are not only related to raw materials,
original structure and heat treatment process, but also closely
related to the shape and size of parts. High frequency induction
heating and quenching are often caused by complex shapes, uneven
thickness or special shapes of parts. After the deformation exceeds
the tolerance, it will fail, and even cause waste. For this reason,
the deformation characteristics and laws of 40Cr steel
high-frequency induction heating quenched gears are tested, and
preventive measures are put forward to reduce gear distortion
defects, and the production effect is good.
Gears are quenched by high-frequency induction heating. Because the
high-frequency induction heating is fast and time-consuming, and
the tissue transformation only occurs in the surface layer, the
overall distortion is small. Generally, the change of the length of
the common normal is small, showing a shrinking trend, and the size
of the inner hole also shrinks and deforms.
