采用逐点增量弯曲的方法对某型火箭的网格式带筋整体壁板进行了试验研究,获得了正确的工艺路线和工艺参数,满足了壁板的外形检验要求。试验证明,增量压弯成形工艺是成形具有一定曲率外形的复杂结构整体壁板的合理而有效的方法。
Adopting the method of incremental bending point by point, a kind of rocket mesh-type ribbed monolithic wallboard was tested and studied. The correct process route and process parameters were obtained, which satisfied the appearance inspection requirements of the wallboard. Experiments show that the incremental bending forming process is a reasonable and effective method for forming a monolithic panel with a complex structure with a certain curvature.
