Mouth and misrun；It carries out school using three rolls plate bending machine to justify, cylinder circular arc nature transition and uniform smooth after the circle of school, the office at longitudinal joint
Portion's camber should meet following formula requirement: E≤(0.1t+1) mm, and wherein E is the length of longitudinal joint camber, and t is the thickness of steel plate
Degree；The cylinder ovality for controlling cylinder and flanged joint carries out the measurement of four diameters to cylinder, and the diameter difference of four measurements is most
Greatly≤25mm, if when shell ring diameter≤2800mm, the diameter difference maximum of four measurements answers≤20mm；
(10) cylinder is repaired: being repaired, mended, ground to drum surface damage.
4. a kind of wind-powered electricity generation shell rolling technique that system is monitored and controlled using light sensation, feature exist according to claim 3
In: during the secondary school circle of the step (9), the step of cylinder ovality of control and flanged joint, is as follows:
It checks: checking whether clean on roller, if any oxide skin, cleared up, to avoid the generation in crater；Check cylinder
The circularity of three positions, respectively 6 positions, 7 thirty position, 9 thirty positions, according to the plate thickness of these three positions, control pair
The circularity requirement answered carries out the circularity for checking cylinder above three position, and subsequent processing, unqualified circularity requirement are entered after qualified
Cylinder using three rolls plate bending machine continue school circle；
Hui Yuan: the side gesture for returning sired results dress is polished smooth, there must not be any acute angle；In circular arc smaller area, with iron block pad in cylinder
Upper polyurethane material is padded in internal side between iron block and inside cartridge, with a thickness of 5-10mm, with Samsung roller rolling machine on the inside of cylinder into
Row upper roller pushes, and the Samsung roller rolling machine includes a upper roller, two lower rolls, pedestal, left and right bracket, a speed reducer；Circular arc compared with
Big region is rolled with four star roller rolling machines, the four stars roller rolling machine include a upper roller, a lower roll, two side rollers, pedestal,
Left and right bracket, a speed reducer；In longitudinal joint region, the circular arc of 1 meter of range inside and outside longitudinal joint is detected, is entered after detection is qualified next
Process detects the underproof circle that continues back and handles；
Cylinder out: cylinder longitudinal joint be in 6 positions when going out cylinder, and longitudinal joint is gone to 7-8 point position behind placement stockyard；
It checks and records: when operator, reviewer are checked using template, needing with straight steel ruler sample plate and cylinder
Between maximum value, by reference to value carry out scene determine cylinder roundness whether meet the requirements, for satisfactory cylinder carry out
Next process, the cylinder for not meeting cylinder requirement place defined stacking region；Tower section number code is recorded on cylinder, and
Carry out mark.
