The invention provides a lofting manufacturing method of a side-pushing horn mouth outer plate, and relates to the field of side-pushing horn mouth lofting. The lofting manufacturing method comprises the following steps: determining the diameter of an outer circle/inner circle of a side thrust horn mouth and the width of the side thrust horn mouth in a side thrust rear view of a ship body; in a side view of the ship body, the bell mouth outer circle and the bell mouth inner circle are equally divided into a plurality of equal parts respectively; in the outer plate molded line library, outer plate rib position lines corresponding to all the equal division points of the outer circle/inner circle of the horn mouth are extracted, all the equal division points of the outer circle/inner circle of the horn mouth are projected to the corresponding outer plate rib position lines, and all the projection points are smoothly connected to form outer circle projections of the outer circle/inner circle of the horn mouth on the outer plate rib position lines; in the lateral thrust rear view of the ship body, the inner circle of the horn mouth is deviated to obtain a real rear view of the outer circle/inner circle of the lateral thrust horn mouth; making a semicircle by taking the auxiliary circle AB as the diameter, and equally dividing the semicircle into six parts; unfolding the auxiliary circle by using a rotation method; the outer circle/inner circle of the horn mouth is unfolded according to the characteristics of a cone.
本发明提供了一种侧推喇叭口外板的放样制作方法,涉及侧推喇叭口放样领域。该放样制作方法包括步骤:在船体的侧推后视图中,确定侧推喇叭口外圆/内圆的直径,以及侧推喇叭口的宽度;在船体的侧视图中,将喇叭口外圆、喇叭口内圆分别平均分为多个等份;在外板型线库中,提取喇叭口外圆/内圆各等分点对应的外板肋位线,将喇叭口外圆/内圆的各等分点投射至对应的外板肋位线上,光顺连接各投射点形成喇叭口外圆/内圆在外板肋位线上的外圆投影;在船体的侧推后视图,偏移喇叭口内圆得到真实的侧推喇叭口外圆/内圆的后视图;以辅助圆AB为直径作半圆,并将半圆弧进行六等分;用旋转法展开辅助圆;根据圆锥特点,将喇叭口外圆/内圆展开。
