Sure thing agree that cheap and ok if enough the pressure of press. For sure everywhere the question about parts quantity - it is the method for single parts production, not hundreds or thousand. And you are correct - real hydroforming is incredible expensive machinery
Didn't understand how guillotine shears could optimize bending operations.
Only one is actual - to cut without burrs because burrs reduce the life of tooling for bending.
I found the thread with the word "press brake". Depends on real thickness and geometry probably could be done with press brake and special tooling. What thickness is this and what model of press brake you do want to use? If I will be you I will think about special punch to produce and bending...
@IFRs
Agree that during manufacture bending radius is factor N1 and the most important. About grain direction - I know that it values but mainly nobody cared seriously to take it in consideration in production, at least we never heard. Moreover the same material from other batch can bring other...
@MateuszM we supply press brake tools but mainly there is no any detailed feedback if everything is working properly.
What I can tell:
1. Nobody buys tool for bottom bending / coining. Maybe only for somewhere in very precise industry but we encountered no any requests.
2. If you have correct...
@dvd - bumping is possible only if accepted. It is not real radius without special tooling
@oharag11 - plate rolls, stamping of conical, then welding together
Based on your quantities and costs I believe you are looking for economic solution))) Spinning lathe I believe more than 1/2 of million...
