Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Such as figure 1 As shown, it is known that branch pipes and main pipes intersect in space to form intersecting connections as an example.

[0021] A method for opening a pipe intersecting opening, which includes the following

[0022] Step 1: According to the intersecting characteristics of the branch pipe 1 and the main pipe 2, use CAD software to extend the outer surface of the branch pipe 1 and the main pipe 2 into a plane figure, and then use the plain line method to draw the intersecting line of the outer surface of the branch pipe 1 and the main pipe 2, and obtain the branch pipe 1 and the main pipe 2. Competent 2 plane intersection graphics, such as figu...

Abstract

The invention discloses an opening method for a pipe intersecting hole. The opening method comprises the following steps that according to the pipe intersecting characteristic, the outer surfaces of pipes are extended into plane figures by CAD software, the intersecting lines between the outer surfaces of the pipes are drawn according to an element method to obtain a pipe plane intersecting hole figure, and the pipe plane intersecting hole figure is printed with a film adhesive according to the ratio of 1 to 1; and the prefabricated pipes are positioned and wrapped with the printed film adhesive, the intersecting lines are drawn on the prefabricated pipes according to the figure of an intersecting hole in the film adhesive, opening is conducted, and opening of the intersecting hole between the prefabricated pipes is completed. The opening hole is simple and convenient to operate, high in accuracy and high in generality. Therefore, the production and manufacturing cost can be reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for opening holes at intersecting openings of pipes. Background technique [0002] At present, for the through-hole openings of intersecting bodies, the opening position and opening size have been determined in the form of data scribing. Because there is a certain degree of distortion in the intersecting body of the curved surface, it is generally inconvenient to manually measure the data and mark the line directly on the pipe, and it requires a certain amount of manpower and material resources, resulting in high production costs. [0003] In addition, manual marking on the pipe will inevitably lead to errors, reducing the accuracy of the opening of the intersecting opening, and even dislocation of the opening of the opening, dimensional deviation, etc., resulting in certain economic losses. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a pipe intersecti...
