Embodiment 1
[0028] A method for casting two kinds of shaft castings of the main shaft of a wind power generating set, that is, 1.5MW series, the method includes the following steps:
[0029] a. Design pouring system: The pouring system is composed of sprue and runner. The sprue is bent, and there is a filter screen for filtering molten iron between the runners, and the bottom pour is open pouring;
[0030] b. Mold production: use a special sand box for resinization, the mold is made of resin, the interior is made of wood, the surface is made of resin, the template is made of steel and wood structure, and after the design is completed, it is molded with resin sand;
[0031] c. Modeling: Vibration compaction is used to make a sand box with a shape notch. Before modeling, place the sand-separating cold iron on the hot joint, that is, the position where the wall thickness of the casting is very different, generally the thick part of the casting; then use The bosses of the cold iron are fixed,...
Embodiment 2
[0042]1. A method for casting the main shaft of a wind power generating set, that is, two types of shaft castings of the 2.5MW series, is characterized in that the method includes the following steps:
[0043] a. Design pouring system: The pouring system is composed of sprue and runner. The sprue is bent, and there is a filter screen for filtering molten iron between the runners, and the bottom pour is open pouring;
[0044] b. Mold production: use a special sand box for resinization, the mold is made of resin, the interior is made of wood, and the surface is made of resin. The formwork adopts steel-wood structure. After the design is completed, it is molded with resin sand;
[0045] c. Modeling: Vibration compaction is used to make a sand box with a shape notch. Before modeling, place the sand-separating cold iron on the hot joint, that is, the position where the wall thickness of the casting is very different, generally the thick part of the casting; then use The bosses o...
