Embodiment 1
[0019] A forging process for a wind power main shaft, comprising the steps of:
[0020] 1), select the bar material, and inspect the bar material composition as C: 0.3%, Mn: 0.5%, Si: 0.2%, S: 0.02%, P: 0.02%, Cr: 1.3%, Ni: 1.3%, Mo: 0.15 %, the balance is Fe;
[0021] 2), blanking, using a circular saw to saw from the bar to obtain the required bar blank;
[0022] 3), use a kind of pre-forging processing device to process, and the processing time is 1.5 minutes. The above-mentioned a kind of forging pre-processing device includes a frame, a casing, a motor bracket, a ballast removal port, and an inner cylinder as shown in the figure. The casing is welded on the frame, the left side of the casing is welded with a motor bracket, and the bottom of the casing is funnel-shaped and welded with a ballast removal port. The two sides of the inner cylinder are suspended in the casing by the bearings with seats fixed in the center of the two sides of the casing. The right section of t...

[0029] A forging process for a wind power main shaft, comprising the steps of:
[0030] 1), select the bar material, and inspect the bar material composition as C: 0.33%, Mn:0.6%, Si:0.3%, S:0.03%, P:0.03%, Cr:1.5%, Ni:1.5%, Mo:0.20 %, the balance is Fe;
[0031] 2), blanking, using a circular saw to saw from the bar to obtain the required bar blank;
[0032]3), use a kind of pre-forging treatment device to process, and the treatment time is 2 minutes. The above-mentioned a kind of forging pre-treatment device includes a frame, a casing, a motor support, a ballast removal port, and an inner cylinder as shown in the figure. The casing is welded on the frame, the left side of the casing is welded with a motor bracket, and the bottom of the casing is funnel-shaped and welded with a ballast removal port. The two sides of the inner cylinder are suspended in the casing by the bearings with seats fixed in the center of the two sides of the casing. The right section of the inner cyl...
Embodiment 3
[0039] A forging process for a wind power main shaft, comprising the steps of:
[0040] 1), select the bar material, check the bar material composition as C: 0.38%, Mn: 0.8%, Si: 0.4%, S: 0.035%, P: 0.035%, Cr: 1.7%, Ni: 1.7%, Mo: 0.30 %, the balance is Fe;
[0041] 2), blanking, using a circular saw to saw from the bar to obtain the required bar blank;
[0042] 3), using a pre-forging processing device for processing, the processing time is 3 minutes, said a pre-forging processing device, as shown in the figure, includes a frame, a casing, a motor bracket, a ballast removal port, and an inner cylinder, and the The casing is welded on the frame, the left side of the casing is welded with a motor bracket, and the bottom of the casing is funnel-shaped and welded with a ballast removal port. The two sides of the inner cylinder are suspended in the casing by the bearings with seats fixed in the center of the two sides of the casing. The right section of the inner cylinder is in ...
