AI Technical Summary
In the prior art, the hinge shaft is prone to cracking at the riveting end, which leads to a decrease in performance and assembly reliability. Furthermore, adding a tempering process will increase production costs and affect production efficiency.
After the thread rolling process, the riveting end of the hinge shaft is locally heated by a high-frequency heating device to achieve the tempering process, avoiding the use of a mesh belt furnace. Combined with photoelectric sensors to detect material jamming, the height of the high-frequency heating conductive tube is adjusted to accommodate hinge shafts of different lengths.
It effectively prevents cracking at the riveted end of the hinge shaft, maintains the hardness of other parts, avoids increased production costs and time conflicts, and improves production efficiency.
