Abstract

The invention provides a quenching device. The quenching device includes a spiral coil quencher which is surrounded by a hollow copper pipe, wherein one end of the spiral coil quencher is a feeding end and the other end is a discharge end. A rail for workpiece running is arranged in the spiral coil quencher. A resistance wire is arranged in the hollow copper pipe, wherein two ends of the hollow copper pipe are connected with a heater. The spiral coil quencher is formed by the hollow copper pipe in a surrounded mode, a workpiece traveling in the spiral coil quencher is subjected to quenching treatment through the hollow copper pipe, the continuous quenching treatment of small parts can be realized, the effect of heat treatment to the processing workpiece can be changed, the adjustment of the heat treatment can be more precisely controlled, and not only is the work efficiency improved, but also the stability of the effect of the heat treatment is improved.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a quenching device. Background technique [0002] Heat treatment is an important basic technology in the machinery industry. Through heat treatment, the internal structure of steel can be changed, thereby improving the performance of steel. Proper heat treatment can significantly improve the mechanical properties of steel and prolong the service life of machine parts. Proper heat treatment can eliminate various defects caused by casting, forging, welding and other thermal processing processes, refine grains, eliminate segregation, reduce internal stress, and make the structure and properties of steel more uniform. Due to the various shapes and structures of mechanical parts, different devices are required for heat treatment for different parts. In order to ensure product quality, small areas need to be heat treated one by one, which not only has low work efficiency, but a...
