Technical requirements and quality inspection for heat treatment of drill tail using medium frequency induction heating power supply

The drill tail is an important part of the drill rod of the rock drill. It mainly withstands the high-frequency impact, torsion and bending effects of the piston. It is a typical rod that can withstand various compression, bending and torsion. It has a large frictional effect when in contact with the transmission shaft. , it is a long cantilever beam when working. In addition, the bending of the extension rod, the deviation of the hole from the center and the vibration of various factors cause the drill tail to be subject to great bending stress. It can be seen that the drill tail must have Sufficient fatigue strength, impact toughness and good wear resistance. For this reason, many manufacturers use medium frequency induction heating power supplies for heat treatment. Today, we are not going to talk about the heat treatment process of the drill tail, but we will talk about its heat treatment requirements and quality inspection.
