厚板结构件展开的Pro/E解决方案及结构件库的建立
|
摘要
传统的结构件制造从展开、下料等工序主要以手工作业为主,虽然也能完成生产任务,但生产周期较长,劳动强度较大,制造精度较差,不能与数控切割设备无缝联接。随着CAD/CAM软件的出现,上述问题可以得到解决,本论文是以在企业中应用广泛的三维软件Pro/ENGINEER为平台,整合该软件在结构件三维建模及展开方面的功能,研究并开发了常用的典型结构件的参数化展开结构件库,改善了目前攀钢修建公司的结构件制造工艺流程,缩短了生产周期,提高了制造精度。
论文对制造业中钣金结构件加工时的放样、展开、相贯等问题的现状进行了调研和综述,指出了现在的应用技术主要都是针对薄板钣金件研究开发的。而在实际应用中,处理厚板结构件时常常会遇到一些问题,需要考虑板厚的影响。
论文的主要研究内容有:运用软件的弯曲及装配功能,模拟了结构件装配后相贯处的接触情况,研究了厚板结构件相贯处相贯面的素线过渡情况、相贯面的结合情况,探讨了一些典型的焊接结构件的焊接坡口的开立方法。研究了在三维参数化建模和参数化展开的过程中,如何结合板厚处理技术的方法。并尝试对一些常用的结构件进行了参数化建模和参数化展开。在此基础上,又对典型的焊接结构件进行了分类建库,这样在实际应用中可以直接查找、调用,并以IGES格式输出,与数控切割设备链接,直接进入数控切割工序。
The traditional structural element manufacturing procedures,such as launches,working procedures and so on are treated mainly by the manual work primarily,although it can complete the production task,but the production cycle is long,the labor intensity is big,the manufacture precision is bad,cannot cut the equipment seamless joint with the numerical control.Along with the CAD/CAM software appearance,the above question may be solved,the present paper is take applies widespread three dimensional software Pro/ENGINEER in the enterprise as a platform, entire shoulds the software and launches the aspect in the structural element three dimensional 3D modelling the function,studied and develops the commonly used typical structural element parametrization to launch the structural element storehouse,improves at present to climb the steel construction company the structural element manufacture technical process, reduced the production cycle,increased the manufacture precision.
The paper to the manufacturing industry in the plate work structural element processing lofting,launched,passes through and so on the question present situations to carry on the investigation and study and the summary,had pointed out the present application technology mainly all aims at the thin steel plate sheet metal research development.But when practical application,processing thick plate structural element can meet some questions frequently,needs to consider the thickness of slab the influence.
The paper main research content includes:Using the software curving and the assembly function,after the simulation brings to completion the component assembly passes through place the contact situation,studied the thick plate structural element to pass through place passes through the surface the plain camlets transition situation,passes through the surface the union situation,discussed some model welding structural element welding scarf to draw up the method.Has studied in the process which the three dimensional parametrization modelling and the parametrization launch,how unifies the thickness of slab processing technology the method. And attempted to some commonly used structural elements enters the shape parametrization modelling and the parametrization launches.In this foundation,also carried on the classification to the model welding structural element to construct the storehouse,like this might search,the transfer directly in the practical application,and by the IGES form output, cut the equipment link with the numerical control,entered the numerical control to cut the working procedure directly.
