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 0.16ā (4mm) thick
Temperature 1562 ĀŗF (850 ĀŗC)
Frequency 57-80 kHz
Equipment ā¢ DW-HF-15kW induction heating system, equipped with aĀ remote workhead containing six 1.0 Ī¼F capacitors for aĀ total of 6.0 Ī¼F
ā¢ An induction heating coil, designed and developedĀ specifically for this application.
Process Three different coils are used for this heating application
ā¢ A two turn pancake coil for the blade
ā¢ A eight turn rectangular helical coil for the knives
Pieces are placed in their specific coil for heating. For theĀ blades, the center hole must be heated to 1562 ĀŗF (850 ĀŗC)Ā and for the knife 2/3 of the blade must be heated. DependingĀ on the piece, the steel reaches 1562 ĀŗF (850 ĀŗC) in 13-19Ā seconds. After the metal is preheated it is press stamped.
Results/Benefits Induction heating provides:
ā¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā¢ Configurable heating profiles
ā¢ Faster process times
ā¢ Even distribution of heating
