[0063] The present invention relates to a specific implementation of the manufacturing process of a wind generator casing, including the following steps:
[0064] 1. Machine case processing:
[0065] A. Cutting:
[0066] a. Prepare a steel plate with a thickness of 55mm, a width of 1850mm and a length of 12063.7mm, and roll the steel plate into a cylindrical shape. Use penetration welding to weld the two ends of the coiled steel plate, and correct the weld to make the weld There will be no cracks, pores and slag inclusions. Weld the "cross" or "meter" reinforcement support inside the cylinder to correct the verticality of the inner circle of the cylinder and the vertical lathe worktable. The vertical turning will roughen the end face and outer circle of the workpiece to make the total length of the housing workpiece take 1840mm;
[0067] b. Prepare four right-angle fan-shaped rings with a thickness of 80mm. The inner radius of the ring is 1445mm and the outer radius is 1930mm. The fo...
