Excavator Cylinder Pins Induction Hardening

This Complete Induction Hardening System for Excavator Cylinder Pins is a specialized equipment designed and produced by TY Induction for our customers in manufacturing and serving heavy machinery in construction industry. These pins play a crucial role in the performance and longevity of excavators. Induction Heat Treatment increases the strength and durability of excavator bucket pins.

This Complete Induction Hardening System for Excavator Bucket Pins includes eight (8) items: an IGBT Induction Power Converter, an output transformer, an induction coil, a quenching coil, a CNC quenching system, a closed-loop cooling system for both induction power converter  and Quenching media, a CNC control system and an UPS power.

The Induction Power Supply generates high-frequency alternating current, which is supplied to the output transformer further to induction coil. The coil is designed to produce an intense electromagnetic field, which is responsible for heating the surface of the excavator bucket pins inside coil.

A bucket pin is precisely positioned inside the induction coil during the Induction Heat Treating process. Once the Induction Hardening Equipment starts up, the induction coil starts moving progressively and electromagnetic field generated by the coil rapidly heats the surface layer of the pin.

After reaching the desired temperature, the quenching system starts to work. The pin is quickly cooled with quenching media sprayed from the quenching coil, which usually contains a specialized quenching medium such as oil, water or polymer. Rapid cooling of the heated surface helps transform the metal structure and form a hardened layer. The quenching process significantly improves the hardness, wear resistance and overall strength of the excavator bucket pin. CNC Control systems in Induction Heat Treatment systems precisely regulate the heating and cooling processes. Operators can set specific parameters such as heating time, temperature and traveling speed of induction coil, flow and pressure of quenching medium for consistent and optimized hardening pattern.
