Hello, I have a question to ask you, do a steel hoop, the outer diameter of 1688MM, with 8# steel roll, want to ask next to the long material, 8# channel 43, formula I for (1688-43) *3.14159=5168mm, this material, placed above the rolling machine to roll how, outside diameter it is more than 1688 Oh, I would like to ask, feeding formula should start rolling steel...Is it possible to stretch the roll with a profile bending machine? Can you recommend 1-2 units? It's best to have the approximate price. I'd like to consider whether I can buy one. Thank you
Steel hoop, the outer diameter of 1688MM, with 8# steel roll, theoretical calculation formula for *3.14159=5168mm (1688-43), but this material, placed above the rolling machine to roll bending process, due to tension phenomenon, so roll diameter to be bigger, and the inner groove is also just outside bend channel rolling material should be the theoretical length minus extension length, the best use of section bending machine bending machine die roll, or
Count the amount, and in turn count how much it should be minus 1688, and then do it. Or leave a little margin, roll it repaired.
