一种用于风电轮毂浇注系统的冒口补缩系统及浇注装置

Abstract

本申请提供了一种用于风电轮毂浇注系统的冒口补缩系统及浇注装置，风电轮毂浇注系统包括内模、外模以及在内模和外模之间形成的型腔，型腔包括：对应于主轴连接面的底型腔、对应于风叶连接面的侧型腔、顶型腔以及位于以上型腔之间的连接腔；其中，冒口补缩系统包括：多个第一冒口组；各第一冒口组内均包括多个第一冒口；各第一冒口组设置在外模内，各第一冒口组的位置分别对应于各侧型腔，且各第一冒口组中的第一冒口的冒口颈朝向侧型腔。通过上述冒口补缩系统，能够对与叶片连接的连接面进行充分补缩，更好地防止该部位在凝固收缩时产生缩孔、缩松等缺陷，能够保证与叶片连接的连接面满足风力发电时的性能要求，延长风电轮毂的使用寿命。

Claims

2. The riser feeding system as described in claim 1, characterized in that, Each of the first riser groups independently includes 4 to 10 first risers.

3. The riser feeding system as described in claim 1, characterized in that, The positions of each of the first riser groups correspond to the upper part of each of the side cavities.

4. The riser feeding system as described in claim 1, characterized in that, The riser feeding system further includes a second riser group, which includes a plurality of second risers; The second riser group is disposed in the upper part of the top cavity, and the riser neck of the second riser faces the top cavity.

5. The riser feeding system as described in claim 1, characterized in that, The first riser is a necked riser, which includes: Outlet cover; The neck of the mouth; and, A riser seat, which is connected between the riser sleeve and the riser neck.
