3.Shaped parts quenching series: for a face shaped parts of whole or partial quenching.
4.Large parts quenching Series: The bulky, heavy quality large parts of whole or partial quenching, such as marine gear, dam sluice Heat treating equipment Road, rail, pipeline and other large-scale.
5.Mold surface hardening Series: mold surface induction hardening machine is a cover for large car.

induction hardening machine types

Modern induction hardening machine more power than conventional hardening machine, energy efficient,induction heating equipment environmentally friendly. Can be divided into the following categories:
1 high frequency induction hardening machine gears should be heated: This species is dedicated to all kinds of gear quenching, through this process, so that the gear is more durable and wear-resistant.
2-axis high-frequency induction heating quenching machine: This species is dedicated to a variety of surface hardening shaft, the shaft will increase the surface hardness, wear-resistant and durable.
3 high-frequency induction heating machine quenching machine: This species is dedicated to a single quenching,induction heating generator quenching rail track, rail flat rail quenching quenching.

Introduction and principles of induction hardening machine

This method is only induction hardening machine for strengthening a surface of a workpiece depth,induction forging machine while maintaining a substantially central portion of the microstructure and properties before treatment, and thus obtain high strength, high wear resistance and high toughness synthesis. Because of local heating, it is possible to significantly reduce the deformation hardening, lowering energy consumption reduction.induction melting furnaces It is because of these characteristics with high-frequency hardening, which in the machining industry widely adopted.

induction hardening equipment introduced

super audio induction hardening equipment, high frequency induction is the IGBT power.induction melting furnaces Currently IGBT induction power has experienced three generations. The first took the narrow frequency multi-board as a significant feature. The second generation is a wide frequency range, single board as the main feature. The third generation, from the technical structure on a revolutionary change, to achieve digital control, energy transmission and storage of energy monitoring data, easy to implement standardized management.
induction hardening equipment UHF generally tube-based, MOSFET also has certain development, currently there with IGBT do.Induction annealing machine Environmental pollution has been well known tube high-frequency devices, but it replaced by MOSFET high failure rate, the reference range received limited. IGBT is relatively stable, is now widely used in high-frequency, intermediate frequency fields core devices.

induction hardening machine heating principle

induction hardening machine induction heating, induction heating principle engineer explained that:heat treatment equipment the workpiece into the sensor, the sensor input is generally intermediate frequency or high frequency alternating current (1000-300000Hz or higher) hollow brass. Generating an alternating magnetic field with the frequency of the induced current in the workpiece, the workpiece induced current distribution is uneven, the surface of strong, weak in the interior,Induction soldering equipment the center portion close to 0 by using the skin effect enables rapid heating of the surface, the surface temperature within a few seconds up to 800-1000 o C, and the temperature rise is small core parts.

Note the use of induction hardening machine

induction hardening machine room should be well ventilated, kept clean, tidy and dry. The device must have two more to start operation, and specify the person in charge of the operation.heat treatment equipment The operator should be familiar with and abide by quenching equipment rules, and regulations Wear protective equipment. Workpiece should deburring, iron and grease, or prone to arcing, but also to prevent the workpiece when operating in contact with the sensor to produce arcing. Use induction hardening machine, should pay attention to electrical, mechanical and hydraulic transmission and other safety procedures. Equipment required to repair by hand, before repair discharge of capacitors discharge rods. No live repair.
To prevent burst wounding high induction heating large parts, CNC quenching machine must strictly abide by the rules and appropriate heat treatment process planning large heat during operation. Should be carried out on a large piece by piece ultrasonic testing, where after testing found white spots, loose piece of serious defects such as segregation and prohibit high-frequency heating equipment. Workpiece should deburring,Gold melting machine iron and oil to prevent arcing. Production operations, you must specify the person in charge, the operator must be familiar with and abide by the rules of CNC quenching machine.

induction hardening equipment classification

induction hardening equipment types are divided into: frequency, low frequency, medium frequency, super audio,induction heating equipment HF, UHF several, according to the hardening depth need to select the appropriate frequency. The greater the depth of hardened layer, the lower the required frequency, and vice versa, is higher.
Currently induction hardening to IF, super audio, HF, UHF-based.
IF generally SCR, IGBT induction power to do useful intermediate frequency than the SCR energy saving,induction heating equipment but the price is higher than the SCR. Relatively speaking, IGBT is the development trend, because of its high conversion efficiency, and stable performance, internal soft-switch, not prone to failure.
