Advisor threatening to pull his name from accepted paper that I submitted without his knowledge
You are wrong for putting the name of someone on a paper and submitting it without asking them for permission. Having them as an author communicates to the world that they approved the content and agree with the conclusions. Implicit in that is that they signed off on the manuscript. Some people get angry when this happens even if the paper is fine and they agree with the conclusions. Some don't. This happened to me recently, and even though I didn't agree with the recommendations of the paper, they weren't wrong, scientifically, so I decided to let it go. 

You need to figure out a way to smooth this over with your advisor and to work with them to get edits turned around more quickly. That being said, don't lead the discussion by bringing up the turnaround time issue. That's combative.
