The utility model relates to a cold and heat correction device for thin-walled metal components, which comprises a box body, a heating device, a cooling device and a clamping device. The heating device and the cooling device are respectively arranged at the upper part and the lower part of the box body, the side opening of the box body, the heating device and the cooling device are exposed, and the clamping device is arranged at the top of the box body. When the device is applied, the thin-walled workpiece to be processed is pasted on the side of the box through the clamping device, and the thin-walled workpiece to be processed is contacted with the surface of the workpiece by the heating device and the cooling device, so as to achieve the purpose of heat transfer. In the calibration process, the temperature data of the workpiece is captured in real time by the temperature sensor, and the heating and cooling temperatures are adjusted by the controller to reach the preset temperature. By the heating function, the top fiber is heated and expanded, shrinks and plastic deformation occurs under the constraint of surrounding materials, shortens the fiber length, and the workpiece is concave and bent, and the lower part of the workpiece is in a low temperature state through the cooling device, thus changing the path of heat downward transmission, and achieving the ideal correction effect.
【技术实现步骤摘要】
一种用于薄壁金属构件的冷热校正装置
本专利技术涉及一种用于对薄壁金属构件进行校正的装置,属于变形校正
技术介绍
铝合金航空结构件一般由预拉伸板材铣削加工而成,材料去除量大,结构刚度低,在板材初始应力、加工应力、铣削力、铣削热和装夹等因素的作用下,加工完成后会产生严重的加工变形问题,达不到飞机装配所要求的精度。目前尚不能对航空结构件加工变形进行精确的预测与控制,变形校正是满足飞机装配精度要求的最终保障。航空结构件可分为梁、框、壁板等类型,其中单面分布有大量隔框、加强筋等结构的非对称零件极易产生单方向的弯曲变形。若定义有隔框、加强筋的一面为上表面,则对于向该侧凸起的变形定义为上凸变形,反之为下凹变形。对于下凹变形,可采用压力校正、滚压校正等手段进行变形校正,并且校正效果较好。对于上凸变形工件,则不能采用滚压校正手段,而采用压力校正时又因为压力机臂展等问题限制了压力校正的使用范围。此外,由于零件壁厚小、刚度差,压力校正稳定性差,极易发生变形失稳现象,目前尚缺乏针对下凹变形的校正工艺及设备。对于上凸变形零件 ...
