Embodiment Construction
[0026] see figure 1 , the present invention discloses a method of using a three-roll plate rolling machine to press a grooved bulkhead during shipbuilding, the method comprising:
[0027] According to the diameter of the upper and lower rollers of the three-roller plate bending machine and the gap between the two lower rollers, the upper mold base 2.1 and the lower mold base 3.2 of the upper and lower molds of the mold and the rollers are designed; it is determined according to the effective working length of the three-roller plate bending machine The length of the mould; according to the size of the knuckle of the notch of the grooved bulkhead and the arc at the knuckle, the size of the upper die pressure head and the lower die groove 3.1 of the upper and lower dies is designed.
[0028] Connect and fix the upper mold and the upper roller 1 through the screw buckle, place the lower mold on the two lower rollers, and then drive the upper mold to run downward through the upper ...
