What are the applications of high-frequency quenching equipment for shaft surfaces? High frequency quenching equipment for shaft surface is an induction heating equipment specially used for quenching shaft workpieces, such as straight shaft, crankshaft, eccentric shaft, camshaft, half shaft, gear shaft, spline shaft, smooth shaft, transmission shaft, pin shaft and other shaft workpieces. In order to extend their service life, quenching heat treatment is required.
The working principle of high-frequency quenching on the surface of the shaft: The workpiece is placed in an inductor, which is usually a hollow copper tube with high-frequency AC input. The alternating magnetic field generates the induction current of the same frequency in the workpiece. The distribution of this induction current in the workpiece is uneven. It is strong on the surface, but weak inside, and close to 0 at the center. Using this Skin effect, the workpiece surface can be heated rapidly, and the surface temperature rises to 800-1000 º C within a few seconds, while the center temperature rises very little.
The principle of high-frequency quenching on the surface of the shaft only quenches the surface of the workpiece, with faster heating speed and higher efficiency. It also does not oxidize other parts of the workpiece, and the quality of the workpiece quenching heat treatment is high. The input voltage of high-frequency quenching equipment is usually three-phase 380V 50-60HZ, with power ranging from 50-500kW. The equipment frequency can be selected according to the requirements of the quenching workpiece.
What are the applications of high-frequency quenching equipment for shaft surfaces?
1. Surface high-frequency quenching equipment not only quenches shaft workpieces, but also completes quenching heat treatment of gears, sprockets, and other workpieces (only by replacing sensors), with strong adaptability.
2. Welding of hard alloy cutting tools, welding of diamond cutting heads, such as diamond saw blades, grinding tools, and sawtooth welding.
3. The steel plate is heated and bent into shape. Thermoforming of standard parts and fasteners. Hardware tools are heat permeable, such as pliers, wrenches, etc.
