Embodiment Construction

[0020] refer to figure 1 , figure 2 , a three-dimensional printing method for an internally threaded tube proposed by the present invention, the radius of the outer circle of the internally threaded tube is L, the radius of the inner hole is R, and the thread depth is H. In this method, the internally threaded pipe is completed by layer-by-layer printing threads in the pipe body whose outer circle radius is L and inner hole radius is S, S=L-R-H.

[0021] This method specifically comprises the following steps:

[0022] S1. Establish an internally threaded pipe model and a pipe body model with an outer circle radius L and an inner hole radius S.

[0023] S2. Obtain a thread printing model according to the internal thread pipe model and the pipe body model.

[0024] In this step, the thread print model is equal to the internal thread pipe model minus the pipe body model.

[0025] S3. Obtain a pipe body whose outer circle radius is L and inner hole radius is S.

Abstract

The invention provides a three-dimensional printing method for an inner thread pipe. The three-dimensional printing method is characterized in that the external circle radius of the inner thread pipe is L; the inner hole radius of the inner thread pipe is R; the thread depth of the inner thread pipe is H; the inner thread pipe is formed by layered printing of threads in a pipe body of which the external circle radius is L and the inner hole radius is S, and S=L-R-H. The method particularly comprises the following steps: S1, building an inner thread pipe model and a pipe body model of which the external circle radius is L and the inner hole radius is S; S2, obtaining a thread printing model according to the inner thread pipe model and the pipe body model; S3, obtaining the pipe body of which the external circle radius is L and the inner hole radius is S; and S4, printing the threads on the inner wall of the pipe body according to the thread printing model and the pipe body model. According to the three-dimensional printing method for the inner thread pipe provided by the invention, the problems that the processing difficulty of the inner thread pipe is large and the thread fineness is difficult to control are solved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printing method for an internally threaded pipe. Background technique [0002] Threaded pipe is a very common component in the machinery industry, especially in the connection process. The threaded pipe is connected by thread matching, and the quality of the thread is directly related to the reliability of the threaded pipe. [0003] At present, the thread processing of the threaded pipe is mainly made by rotating the tool. This processing method wastes raw materials secondly. More importantly, when the tool is not controlled properly, it is easy to cause damage that is difficult to repair, which leads to the scrapping of the threaded pipe. Therefore, the production Efficiency and pass rate are difficult to improve. Moreover, since the tool is difficult to carve with precision, it is difficult to further improve the fineness of the thread....
