The invention relates to a manufacturing method of a calabash-shaped outer container of a marine air bag type leak stopper, which is characterized by comprising the following steps of: equally dividing the outer container into n1 parts along the axis direction, straightening and unfolding the divided single-piece outer container graph, projecting the single-piece outer container graph to a two-dimensional plane, drawing an equal-proportion graph A by using CAD (Computer Aided Design) software, drawing an equal-proportion graph B after the allowance is considered again, and respectively manufacturing the graph A and the graph B, so that the calabash-shaped outer container of the marine air bag type leak stopper is manufactured. Cutting the anti-cutting material according to the pattern B, placing the pattern A on the cut anti-cutting material, ensuring that the two axes coincide and are consistent in direction, drawing a molded line along the outer contour of the pattern A, determining a sewing edge distance, and performing sewing forming. The method has the beneficial effects that the three-dimensional model of the outer liner with the specific molded line is designed, the segmentation number of the airbag model with the specific shape is determined, the surface is segmented, unfolded and projected, the molded line of a single segmented body is determined, tailoring is performed by considering the sewing edge distance of the single segmented body, and the gourd-shaped outer liner is simply, rapidly and low-cost manufactured in combination with a specific sewing technique; and the structure reliability can be ensured.

    本发明涉及一种船用气囊式堵漏器葫芦状外胆的制作方法,其特征是:通过对外胆沿轴线方向进行n1等分分割,将分割后单片外胆图形取直并展开,投影到二维平面,利用CAD软件绘制等比例图形A,再次绘制考虑余量后的等比例图形B,分别制作图样A、B,依照图样B裁剪防割材料,将图样A放置在裁剪好的防割材料上并确保两轴线重合且方向一致,沿着图样A外轮廓绘制型线,确定缝合边距并缝制成型。有益效果:本发明设计特定型线外胆的三维模型,确定特定形状的气囊模型的分割数量,将表面分割、展开、投影,确定单片分割体的型线,考虑单片分割体缝合边距进行裁剪,结合特定缝合手法,实现葫芦状外胆简单快速、低成本制作,且可保证结构可靠。
