[0022] when pipe diameter d min =100mm, the maximum angle α between the straightening roller and the straightening direction max When = 20°, the value of each parameter in the roll curve is calculated as follows:
[0023] R1=16×100×π×tg20°=1827.58;
[0024] R2=24×100×π×tg20°=2741.37;
[0025] R3=40×100×π×tg20°=4568.949;
[0026] R4=2.4×100×π×tg20°=274.137;
[0027] R5=30mm;
[0028] L1=1.6×100×π×tg20°=182.758;
[0029] L2=3.2×100×π×tg20°=365.5159;
[0030] L3=4.8×100×π×tg20°=548.2739;
[0031] L4=6.4×100×π×tg20°=731.0319;
[0032] L5=7.6×100×π×tg20°=868.1004.
[0033] Take the roller-shaped symmetry line as the axis of symmetry, make the arc AA / 2 tangent to the arc AB, the arc AB to the arc BC, the arc BC to the oblique line CD, and the oblique line CD to the arc DE Tangent, tangent between arc DE and arc EF can get the generatrix of concave roll curve. Each parameter can be rounded up in a specific application.
[0034] The DC section of the concave roll entrance ...
