Problems solved by technology

[0002] At present, it is known that in the production process of pipeline tees, some tees are very complicated to make, such as herringbone tees, etc., which are generally handmade by hand based on experience, which requires relatively high experience for workers, and the joints have rough lines and large gaps. It causes shortcomings such as heavy welding workload and large flow resistance, and the work efficiency is not very high. Moreover, the shape of the tee made is not beautiful, and it is difficult to meet the design requirements.

Embodiment Construction

[0014] The present invention is a kind of calculation method of computer automatic lofting for pipe opening three-way, which comprises the following steps: the first step, at first establishes a mathematical model, and the mathematical model is as follows;

[0015] α=(π×A) / 180;

[0016] X=α×d / 2;

[0017] Y = ( D - D 2 - d 2 × sin α 2 + d × cos β × ( cos α - 1 ) ) / ( 2 × sin β ) ; ...

Abstract

The invention discloses an automatic lofting calculation method used for a pipeline three-way computer. The method includes the following steps: a first step, a math model is firstly established; a second step, VB language is adopted for programming; a third step, the line outspread drawing of pipe three-way joints can be drawn in form2 after data is input into a form1window, and a template can be manufactured according to the drawing. The invention is established on the basis of relevant math models, and adopts the VB language programming and a lip-read operation interface to input relevant origin parameters, and after the automatic analysis of the computer, the line outspread drawing of pipe three-way joints is drawn finally. With the method, not only the technical requirement to workers can be reduced, the labor intensity of workers is simplified, work efficiency is enhanced, materials are saved and the resistance of pipeline flow is reduced, but also the manufactured three-way has an elegant appearance, which reaches the design requirement.

Description

technical field [0001] The invention relates to a computer automatic lofting method for pipe opening and tees. Background technique [0002] At present, it is known that in the production process of pipeline tees, some tees are very complicated to make, such as herringbone tees, etc., which are generally handmade by hand based on experience, which requires relatively high experience for workers, and the joints have rough lines and large gaps. Cause the disadvantages such as large welding workload and large flow resistance, the work efficiency is not very high, and the shape of the tee made is not beautiful, and it is difficult to meet the design requirements. Contents of the invention [0003] The invention relates to a calculation method for computer automatic lofting of pipe opening tees, which can reduce labor skill requirements for workers, simplify labor intensity of workers, save materials, and reduce pipeline flow resistance. [0004] The present invention adopts t...
