Try removing the wheel and supporting the fork crown with something like a 2x4, so that all of the hammer's force goes into the bolt, and not in flexing the fork blades and compressing the tire. Don't put the fork ends on the floor and pound, you will damage them. I use a 2 pound hand sledge for stubborn quill stems. Give it a good solid hard hit, multiple taps will not do the job. Kano Kroil or PB Blaster are your friends, you might need to turn the bike upside-down and spray into the bottom of the fork to get it to the wedge.
