The invention relates to an LPG transport ship twisted rudder manufacturing process. Firstly, a jig frame is manufactured; pile columns are arranged along the formwork ground lines; positioning the larboard shell plate on the jig frame; welding a welding seam of the shell plate; construction of the rudder blade body part is temporarily finished, and then the rudder blade body part and the twisted guide edge are assembled; the tail rudder blade is matched according to the provided arc sealing plate at the lower end of the twisted guide edge; after integral assembly, all welding seams need to be reinforced and firmly fixed by using the stacking plates; mounting and positioning a rudder ball middle longitudinal structure and other vertical rib plates; another outboard plate is mounted by the same method, and the rudder ball is welded by the same welding process as the rudder blade. The manufacturing process of the twisted rudder of the LPG transport ship aims at solving the problem that in the manufacturing process of the twisted rudder, installation is difficult due to large precision deviation, key and difficult procedures in rudder blade manufacturing are split, the manufacturing process of fine control is conducted one by one, and the requirements for the angle, size precision and form and location tolerance of the rudder blade are met.

    本发明涉及一种LPG运输船扭曲舵制作工艺,首先制作胎架;沿着模板地面线条布置桩柱;将左舷外壳板在胎架上定位;对外壳板焊缝进行焊接;舵叶本体部份施工暂时结束,然后再与扭曲导边进行组装;尾部舵叶根据提供的扭曲导边下端圆弧封板进行配作;整体组装后所有焊缝都需要用码板加强固定牢靠;安装定位舵球中纵结构及其余垂直筋板;同样的方法安装另外一舷外板,采用与舵叶同样的焊接工艺进行焊接舵球。本发明所述的LPG运输船扭曲舵制作工艺,目的是为了解决扭曲舵制作过程中出现的因精度偏差大造成的安装困难问题,对舵叶制作中重点和难点工序进行拆分,逐一进行精细控制的制作流程,来保证舵叶的角度,尺寸精度,形位公差要求。
