Problems solved by technology
At present, most of the local induction heat treatment of the pin shaft is completed on the vertical quenching machine tool, which adopts one-way stroke scanning, and the production efficiency is low
There is also special equipment for induction heat treatment using double rollers to realize continuous horizontal feeding of pin shafts, but it is difficult to apply to short-pin parts and the quality is unstable
There are also special equipment for induction heat treatment using servo or stepping motor system. The feeding method is continuous, and it is difficult to eliminate the cumulative error caused by the length of the pin shaft; low production efficiency

Description
technical field [0001] The invention relates to a special equipment for induction heat treatment, in particular to a special equipment for high-efficiency induction heat treatment of a chain pin shaft with two-way strokes. Background technique [0002] In chain manufacturing, in order to improve the comprehensive mechanical properties of the chain, the pin shaft often needs local induction heat treatment, that is, the middle part of the pin shaft is subjected to induction heat treatment to increase the hardness, while the two ends of the pin shaft are not subjected to induction heat treatment to maintain the riveting performance of the assembly process. At present, the local induction heat treatment of the pin shaft is mostly completed on the vertical quenching machine tool, which adopts one-way stroke scanning, and the production efficiency is low. There are also special equipment for induction heat treatment using double-rollers to realize continuous horizontal feeding of ...
