三辊连轧管机孔型设计软件的开发

Development of Pass Design Software for 3-roll Mandrel Pipe Mill

分析三辊连轧管机的孔型特点及孔型设计步骤,利用Lazarus软件开发出三辊连轧管机孔型设计软件。该软件可以快速校核孔型参数,进行孔型轮廓和金属轮廓参数化绘图,并根据变形金属与工模具脱离点的坐标,分析生产事故情况,指导生产。利用Lazarus软件进行孔型设计方便快捷、通用性强、精度高;可针对不同的三辊连轧管机组及其现场工况条件进行计算;还可以将孔型设计参数与现场生产和质量情况存储到数据库内,作为新孔型设计依据。

Pass features and pass design steps for 3-roll mandrel pipe mill are analyzed. A pass design software for 3-roll mandrel pipe mill is developed by using Lazarus. This pass design software can quickly verify the pass parameters, make parametric drawings of the pass profile and the metal profile, analyze the production situations according to the coordinates of metal-tool seperating points, and guide the production. Lazarus is a convenient and quick tool for pass design and has good universality and high precision. Calculations can be done for different types of 3-roll mandrel pipe mills and various field conditions. The pass design parameters as well as the production and quality information can be stored in a database to serve as basics for designing new passes.
