排辊成形工艺参数化设计系统集成开发技术

排辊成形是利用若干组小排辊将带钢续弯卷成管筒的一种辊式成形工艺,是制造焊管的重要加工技术。现代的排辊成形工艺设计涉及到CAD,CAE和知识管理等多个方面的技术,技术平台的集成至关重要。本文以Visual Basic为开发平台,利用Visual Basic与ACCESS数据库、MATLAB与ANSYS的接口技术,将参数设计、有限元模拟和知识管理集成,开发了直缝焊管排辊成形工艺设计系统。通过该系统可以实现直缝焊管排辊成形过程的工艺参数管理、机组的轧辊设计、花型设计、工艺参数设计以及CAD/CAE建模仿真。该平台可以为工程人员进行直缝焊管工艺设计提供重要参考。

Integrated development technology of parametric design system for cage roll forming process

The cage roll forming is a kind of forming processes that a steel strip is bended into round shape by a number of forming cage rolls. It is an important processing technology for manufacturing pipes. The advanced process design technology for a cage roll forming process involves CAD, CAE and data management, so the integration of different platforms is very important. A parametric design system for the cage roll forming process was established based on VB. Through the interface technology of VB to ANSYS, MATLAB and ACCESS database, the parameter design, finite element simulation and database were integrated, then a process design system was developed. This system can manage the parameters for the whole roll forming process, design new rolls, flower patterns, determine forming parameters, and realize automatic CAD/CAE modeling and simulation. This platform can provide an important guide for engineers in pipe manufacturing process.
