Background technology
It is frequently encountered by the special alloy steel higher containing alloying elements such as Ni, Cr, V, Mo in high frequency heat treatment quenching process
Surface hardening part, this quenching part has on high-frequency hardening machine sees that oil catches fire, meets the characteristic that water ftractures, and it is through high-frequency induction electricity
Stream, by after rapid for surface heating, needs using quenching oil or non-aqueous medium as its cooling medium, otherwise can not reach surface
The technical requirements of quenching.Oil cooling can catch fire, water cooling excessive velocities, and quenching workpiece occurs crackle or cracking phenomena；Natural
Air rate of cooling is excessively slow, and the case hardness of quenching workpiece does not reach.The traditional method solving the above problems is very simple, buys symbol
Close the quenching liquid requiring as cooling medium.However, the domestic 1-2 of the market price of one ton of finished product quenching medium ten thousand, import 3-5
Ten thousand RMB, its price is costly, relatively costly, and cost performance is relatively low, cannot collect on High-frequency machine again.Therefore urgently new
Quenching cooling technique and quenching cooler solve the above problems.
Content of the invention

The present invention adopts compressed air as the cooling medium of induced surface hardening, its not only have structure simple,
Easy to operate advantage, also has safe and reliable, economical and practical, with low cost, the measured advantage of surface hardening matter.
Brief description
Accompanying drawing 1 is the structural representation of invention.
In fig. 1：1 be compressed air container, 2 be pipeline, 3 be air valve, 4 be induction coil, 5 be heat treated part, 6
For special fixture.
Specific embodiment
The cooling technique of the present invention：First by heat treated part 5 clamping in special fixture 6, and induction coil 4 is made to be placed on
The periphery of heat treated part 5；Secondly being passed through high frequency induction current in induction coil 4 makes heat treated part 5 surface heat rapidly
Heat up；3rd when heat treated part 5 surface temperature reaches hardening heat, cuts off induction coil 4 power supply；4th opens air valve 3,
Compressed gas in compressed air container 1 are ejected into rapidly the surface of heat treated part 5, so that heat treated part 5 surface is obtained and quench
Fire tissue.Compressed gas are compressed air；Compressed gas are the mixed gas of air and ammonia；Compressed gas can timely adjustment pressure
Power.
Below in conjunction with accompanying drawing, explanation is further explained to the chiller in the present invention：
As shown in Figure 1, heat treated part 5 is clamped and rotates and move by special fixture 6；Induction coil 4 covers on having distance
The periphery of heat treated part 5；It is provided with the cooling medium through flow hole of several sensing heat treated parts 5 in induction coil 4；Several
Cooling medium through flow hole is communicated with compressed air container 1 by pipeline 2, and is provided with air valve 3 on pipeline 2；Compressed air 1 is added
It is the mixed gas containing ammonia after ammonia.
The present invention makes heat treated part 5 using the mixing blast injection containing ammonia to the surface of heat treated part 5
Be obtained in that faster than natural ventilating air rate of cooling during cooling, the cooling effect slower than cooling oil rate of cooling such that it is able to
The cooling reaching special alloy steel high-frequency surface hardening requires.
