Induction Preheating Blades And Knives
Description
Induction Preheating Blades And Knives With High Frequency Induction Heating Units
Objective Preheating various size blades and knives for garden tools
Material Steel pieces of various size 0.16โ (4mm) thick
Temperature 1562 ยบF (850 ยบC)
Frequency 57-80 kHz
Equipment โข DW-HF-15kW induction heating system, equipped with aย remote workhead containing six 1.0 ฮผF capacitors for aย total of 6.0 ฮผF
โข An induction heating coil, designed and developedย specifically for this application.
Process Three different coils are used for this heating application
โข A two turn pancake coil for the blade
โข A eight turn rectangular helical coil for the knives
Pieces are placed in their specific coil for heating. For theย blades, the center hole must be heated to 1562 ยบF (850 ยบC)ย and for the knife 2/3 of the blade must be heated. Dependingย on the piece, the steel reaches 1562 ยบF (850 ยบC) in 13-19ย seconds. After the metal is preheated it is press stamped.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Configurable heating profiles
โข Faster process times
โข Even distribution of heating
