Based on the design, I'm guessing the bend is the weld itself. If so, you can try to bend it back, but you will most certainly break the mount off. Once that happens, you have a couple options going forward.
First off, if the piece isn't straight, you need to straighten it. I'd recommend putting the bracket in a vice with wood on either side. If that doesn't work, move the part up to where the bend is and use a hammer to straighten it. You can try to use tape or whatever you have to protect the finish.
Next, you can either use JB Weld or actually weld the part back on. Welding would be most sturdy, but it will damage the gold coating right around where the heat is applied. JB Weld won't damage anything and is nearly invisible...BUT, it's not nearly as strong. This is a light weight installation, so you might be able to get away with JB Weld. If not, find a local machine shop or a friend with a welder (arc welder is much preferred to oxy-acetylene in this case).
Good luck!
