Problems solved by technology

[0006] (1) For pipelines with strange orientations, the actual spatial layout requires that the pipelines have a unique orientation. The simulation can only judge whether the pipeline orientation scheme can be bent, but it cannot solve the problem that the pipeline orientation method cannot be bent.
[0007] (2) The types of situations where CNC cannot bend steel pipes have not been summarized, summarized and improved, and the problem cannot be solved efficiently when encountering this problem in the actual production process

Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] The classification method of interference problems in the process of CNC pipe bending. There are mainly two types of interference problems in the process of steel pipe CNC bending. One is interference with the ground, which makes the steel pipe unable to be bent, and the other is the structure of the machine tool (such as bending die). interference, causing the steel pipe to be unable to continue bending;

[0023] The interference with the ground is divided into two categories: the first category, the steel pipe bending action process interferes with the ground but the final position does not interfere; the second category, the steel pipe final bending position interferes with the ground;

[0024] The interference with the machine to...

Abstract

The invention discloses a method for classifying and handling interference problems in a numerical control pipe bending process. The problems are classified as follows: two kinds of interference problems mainly appear in the steel pipe numerical control bending process, one is that steel pipes make interference with the ground, thereby being incapable of being bent, and the other one is that the steel pipes make interference with a machine tool structure, thereby being incapable of continuing to be bent; interference between the steel pipes and the ground is classified into two kinds, one is that the steel pipe bending action process except for the final position makes interference with the ground, and the other one is that the steel pipe final bending position makes interference with theground; and interference between the steel pipes and the machine tool structure is classified into two kinds, one is that the steel pipe bending process except for the final position makes interference with a machine tool, and the other one is that the steel pipe final bending position makes interference with the machine tool. The method solves the common interference problems in the steel pipe numerical control bending process. By generalizing the common pipe bending interference problems and giving corresponding solving methods, the overall problem brought by adding a transition connection point is avoided, and the steel pipe bending strength of enterprises is improved.

Description

technical field [0001] The invention relates to a classification method and a processing method for interference problems in a numerically controlled pipe bending process. Background technique [0002] Elbows are widely used in railways, automobiles, ships, aerospace and other fields to transport gas, liquid, solid or other forms of working media. Bend pipes are often limited by the spatial structure layout, and their unique path is unique, so the pipes cannot be formed by CNC bending. In this case, most of them have to adopt other methods such as welding or joint connection to make the transition. The use of this transitional pipeline connection method increases the possibility of pipeline leakage and also causes great difficulties for maintenance. [0003] Each simmering and bending of the steel pipe is realized by the three-axis action of feeding, rotating and bending of the CNC machine tool to realize the pipe fitting forming. The CNC machine converts the input X / Y / Z ...
