Description

一种航空发动机整体叶盘的加工方法及设备 技术领域
本发明涉及一种航空发动机整体叶盘的加工方法及设备,属于电火花加工技术领域。
背景技术
整体叶盘是把发动机转子的叶片和轮盘设计成一个整体,采用整体加工或焊接(叶片和轮盘材料可以不同)方法制造而成,无需加工榫头和榫槽。
与传统的叶片和轮毂装配结构相比,这种整体结构的优点是:叶盘的轮缘径向高度、厚度和叶片原榫头部位尺寸均可大大减小,减重效果明显;发动机转子部件的结构大为简化;消除了分体结构榫齿根部缝隙中气体的逸流损失;避免了叶片和轮盘装配不当造成的微动磨损、裂纹以及锁片损坏带来的故障,从而有利于提高发动机工作效率,可靠性得以进一步提升。
整体叶盘具有如此多的优点,但是在整体叶盘的加工过程中,也遇到了很多的问题。现阶段整体叶盘加工主要采用数控铣削和电化学电解加工两种方式,但都各有利弊。
数控铣削技术是整体叶盘常用的加工方法,整体叶盘通道是特殊曲面型腔结构,传统的铣削加工方法采用立铣刀分层侧铣,侧铣刀具受径向力作用,随着通道铣削深度的加深刀具悬伸量加长,刀具的刚性变差,在径向力的作用之下刀具变形、振动、磨损加剧,力口工效率显著降低。针对整体叶盘复杂通道侧铣加工存在的问题,数控铣削开槽插铣方法解决了一些上述问题,但是,数控铣削切削力大,叶片易受变形,刀具与叶盘易发生干涉,刀具磨损严重等问题依然存在。整体叶盘另一种加工方法是数控电解加工,电解加工也存在一些不足之处,加工的影响因素多,且加工稳定性和重复性都比较 差,尤其是加工闭式整体叶盘零件时,叶盘流道弯扭复杂,且冲液问题也难于解决。电流要求高,电解液和电解产物需要专门处理,环境污染严重。
发明内容

机床的X轴、Y轴带动叶盘毛坯水平移动;机床的Z轴、Z2轴带动上下线臂垂直移动,控制加工区域钼丝开口的大小;叶盘的毛坯零件装夹在C轴转台上,通过C轴控制叶盘水平旋转,使钼丝可以切割不同角向的叶片,机床的A轴带动叶盘分别围绕X旋转,通过和U轴、V轴联动实现多角度切割轨迹;Z1轴带动叶盘垂直移动,调整叶盘的切割高度;U轴、V轴带动上线臂水平移动偏摆钼丝切割角度。
一种航空发动机整体叶盘的加工方法,含有以下步骤;
步骤1;机床的X轴、Y轴带动叶盘毛坯水平移动到起切点;
步骤2;Z1轴带动叶盘垂直移动,调整叶盘的切割高度。

本发明的优点是将传统的线切割加工原理应用到整体叶盘流道开槽掏料加工中,由于电火花线切割加工中无切削力及应力,加工振动变形问题影响很小,同时也不存在刀具磨损问题。大幅降低了加工成本,提高了加工效率。
