Dual ring rolling production process of thin-sheet wind driven generator

Abstract

The invention discloses a dual ring rolling production process of a thin-sheet wind driven generator, and belongs to the technical field of machine manufacturing. The task of the invention is that when a wind driven flange forged piece with higher quality, larger diameter and smaller thickness is manufactured, the upper surface and the lower surface are smooth, without warping, the dimension is easy to control, and the production yield is high. The key points of the technical scheme are that the production process comprises a dual blank preparation section, a dual blank performing section, and a dual ring rolling forming section. The quality of the single blank is the same as that of two thin-sheet wind driven generator flange blanks; the height of the circular ring-shaped fine blank is the same as that of circular ring-shaped fine blanks of the two thin-sheet wind driven generator flange blanks; and the circular ring-shaped fine blank is divided into two parts by a saw belt, and then the two parts are cut into qualified parts. When the wind driven flange forged piece with higher quality, larger diameter and smaller thickness is manufactured, the dimension is easy to control, the technical effects of the upper surface and the lower surface are smooth, without warping, and the production yield is high are achieved. The production process is simple in structure.

Description

【Technical field】 [0001] The invention belongs to the technical field of mechanical manufacturing. In particular, it relates to a manufacturing method for flange forgings. 【Background technique】 [0002] At present, in the machinery manufacturing industry, the flange forgings are a kind of ring forgings, and the process of making small-quality and small-sized ring forgings is very mature, and the production can be organized by either free forging or die forging; but in When making sheet wind power flange forgings with larger mass, larger diameter and smaller thickness, the production can only be organized by free forging. However, the free forging method is used to make sheet wind power with larger mass, larger diameter and smaller thickness. When the flange forging is used, it has its shortcomings. The shortcomings are: the upper and lower surfaces of the sheet wind power flange forging are seriously warped and deformed, the specifications and dimensions are not well contr...

Problems solved by technology

[0002] At present, in the machinery manufacturing industry, flange forgings are a kind of ring forgings. The technology for making ring forgings with small mass and small size is very mature, and the production can be organized by free forging or die forging; but in When making sheet wind power flange forgings with larger mass, larger diameter, and smaller thickness, the production can only be organized by free forging. When it comes to flange forgings, it has its disadvantages. The disadvantages are: the upper and lower surfaces of thin-section wind power flange forgings are seriously warped and deformed, the specifications and sizes are not easy to control, and the production pass rate is low.
