High frequency quenching of Beichen Yike optical axis

  High frequency quenching of optical axis
  Application:   When the workpiece is subjected to alternating loads such as torsion and bending, the surface layer is required to bear higher stress or wear resistance than the center, so it is necessary to put forward strengthening requirements for the workpiece surface Process method:   The combination of rapid heating and immediate quenching and cooling enables the surface of the steel parts to be processed to reach the quenching temperature through rapid heating
The surface layer is only hardened to martensite, and the center is still the annealing (or normalizing and quenching and tempering) structure with good plasticity and toughness that has not been quenched Main methods   Induction heating surface quenching (high frequency, medium frequency, power frequency), flame heating surface quenching, electric contact heating surface quenching, electrolyte heating surface quenching, laser heating surface quenching, electron beam heating surface quenching Basic principle of induction heating surface quenching:   Place the workpiece in the inductor made of hollow copper tube, and after the medium frequency or high frequency AC is connected, the induced current of the same frequency will be formed on the workpiece surface to quickly heat the surface of the part (the temperature can be increased by 800-1000 degrees within a few seconds, and the core is still close to the room temperature, then immediately spray water for cooling (or oil quenching) to harden the surface layer of the workpiece
) Compared with ordinary quenching, induction heating surface quenching has the following advantages:   1
The heating speed is very fast, which can expand the A-body transition temperature range and shorten the transition time 2
After quenching, very fine cryptocrystalline martensite with slightly higher hardness (2-3hrc) can be obtained on the surface of the workpiece 3
The workpieces treated by this process are not easy to oxidize and decarbonize, and even some workpieces can be directly assembled for use after treatment 4
The quenching depth is easy to control and realize automation Customer site:   In order to approach the actual production to the greatest extent, we have carried out the actual quenching for the optical axis parts at the customer's site
We have used a vertical shaft quenching machine and a 40kW full digital UHF induction heating equipment for actual production The technical requirements for participating in this production activity are: hardness HRC60, hardening layer 0
7mm
After simple debugging, the actual production was carried out
Our 40kW UHF induction heating equipment fully meets the production requirements
