Embodiment 1

[0022] like figure 1 Shown is the projection of the curved shell plate of a certain part of the hull plate. It is required to open a round hole of R586mm at the intersection of the 2000mm waterline and the FR104 rib on the curved shell plate. figure 2 is the axonometric schematic diagram of the opening of the curved shell. Use the opening method of the curved panel of the present invention to open the above-mentioned round hole, use CAD software to expand along the outer surface of the curved shell plate to obtain image 3 The plane graph shown. Cut out the opening part of the planar figure and print out the opening figure with adhesive film in a ratio of 1:1. The opening figure contains the 2000mm waterline and FR104 rib position line as the opening positioning line 3, such as Figure 4 shown. Overlay the printed hole pattern 2 on the curved shell plate 1 as shown in Figure 5 , to ensure that the 2000mm waterline and FR104 rib line on the film paper overlap with the 200...

Abstract

The invention relates to a hole-opening method of a curved panel. The method is characterized by comprising the following steps: extending the surface of a three-dimensional curved panel to a plane figure by using drawing software; printing the opened part in the plane figure in a proportion of 1: 1 to obtain a hole-opening figure; and covering the curved panel with the hole-opening figure to open a hole. According to the hole-opening method of the curved panel provided by the invention, lineation is replaced by a method of pasting the plane hole-opening figure, so that the method is simple and convenient, high in precision and good in universality, the production and manufacture costs can be lowered, the work efficiency is improved, and the hole-opening method is suitable for various opened holes in a three-dimensional panel surface.

Description

technical field [0001] The invention relates to the field of opening holes of curved panel parts, in particular to a method for opening holes of curved panel parts. Background technique [0002] At present, for the opening of curved panels in the hull structure, the form of data marking has been used to determine the position and size of the opening. Due to the certain degree of distortion of the curved panel, it is not convenient to manually measure and draw the data on the curved panel, and it requires a certain amount of manpower and material resources, resulting in high production costs. In addition, manually drawing lines on curved panels will inevitably lead to errors, reduce the accuracy of openings, and even dislocation of openings, size deviations, etc., resulting in certain economic losses. [0003] In order to solve the above-mentioned problems, various devices for marking lines or opening holes in curved panels have been developed. For example, the Chinese inve...
