I've translated the first two verses, roughly. It's not perfect, but good enough.
Wait! Peeling the wicked fang
The laughing evil Death Armor
I will! We won't let you get away!
Dangerous Superior Brave Change!
Justice is held in the hearts of people
It's our duty, blades held to the sky!
Draw it out, the burning Atomic Fire Blade!
Oh the spinning limitless Cyclone Blade!
Protecting our beautiful country
Swordsmen of love and justice
Chouken Sentai Blade Braver
