China gear high frequency quenching equipment

Gear high-frequency quenching equipment uses induction heating, then what is the working principle of gear high-frequency quenching equipment? What are the uses of gear high-frequency quenching equipment? Let Haituo Electromechanical give you a detailed introduction!



First, the working principle of gear high frequency quenching equipment

High-frequency quenching refers to a heat treatment method in which a surface of a workpiece is locally heated and cooled by using a high-frequency current (30K-1000KHZ) to obtain a surface hardened layer, which is a surface deepening of a workpiece such as a gear, and the core is substantially maintained. It is unchanged, so it has high intensity, high wear resistance and high toughness. It is also due to local heating, so it can significantly reduce quenching deformation and reduce energy consumption.

 

Second, the use of gear high-frequency quenching equipment

1. Heat treatment industry: high-frequency quenching heat treatment of various power tool gear shafts; various gears, various forks, various spline shafts, transmission shafts, various small shaft crank pins, various rocker arms, rocker arms High-frequency quenching heat treatment such as shaft; high-frequency quenching heat treatment of hardware tools, such as vise, hammer, pliers, wrench.

2. Quenching and tempering of various workpieces, such as induction quenching of shafts, gears, discs and other parts.

Hardened workpiece size range:

  Shaft type: φ10-300mm L: 50-1500mm

  Gear type: φ20-300mm H: 10-600mm


 [Gear quenching machine] has the functions of continuous quenching, simultaneous quenching, segmental continuous quenching, segmentation and simultaneous quenching;

  Frequency control system, servo motor drive, ball screw drive;

  It has two cooling methods of immersion liquid and spray liquid, and can be equipped with integrated quenching liquid circulation cooling system;

  It adopts numerical control system or PLC touch screen control, without programming, convenient operation, real-time display, can store 126 programs, concentrate heating→positioning→spraying and time control on machine tool control system, easily realize workpiece positioning, scanning, and through PLC and Power supply online for fully automated production;

  Repeated positioning accuracy, small size, light weight and easy maintenance;

  According to the needs of customers, we can customize semi-automatic/automatic high-frequency quenching machine.



Third, the principle of gear induction induction heating

The workpiece such as a gear is placed in the inductor, and the generated alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of the induced current in the workpiece is uneven, and the skin effect can be utilized by using the skin effect. The surface of the workpiece such as gears is heated rapidly, and the surface temperature rises to 800-1000 ° C in a few seconds, while the core temperature rises very little to meet our requirements.


The above is the working principle of the gear high-frequency quenching equipment brought by Haituo Electromechanical. What are the uses? I hope to provide some help for everyone! If you need to buy gear high-frequency quenching equipment, then look for Haituo Electromechanical!
