Parametric Design, Based On The Reduction Of The Pro / E System

Steel plays an incomparable role in daily life and economic construction ascommonly used metal material. High energy consumption of the iron and steelindustry has become a prominent problem that have serious impact on economicdevelopment. To promote China's iron and steel industry energy conservationand the development of circular economy and low carbon economy, to promotethe sustainable development of the iron and steel industry, it is imperative toestablish the short process of steel production line and R&Denvironment-friendly metallurgical equipment. Twin-roll casting technologyfundamentally changes the traditional steel production. Casting and rolling twoprocesses are combined into one, which significantly shortening the productionprocess of the steel material. It is consistent with the iron and steel recyclingeconomy, environment-friend, and sustainable development process.In the course of metallurgy mechanical design and drafting, the designersspend a lot of time and effort to check the manual and calculate, then establishinteractive modeling. Lots of duplication of design and drawing will increase thelabor intensity of the designers and reduce design efficiency. Therefore, thedevelopment of a typical component design, not only can improve the efficiencyof product design, but also provide three-dimensional geometric models, andmaterial information related to the simulation and analysis for subsequentanalysis and simulation system.In this context, this paper takes caster screw down system for example,carries out the subject research that screw down parametric CAD systems basedon Pro/ENGINEER. This paper analyzes the research status of the castingtechnology and technical bottlenecks, theory and research of parametrictechnology, and the secondary development of Pro/ENGINEER domestic andinternational. On this basis, a new type screw down system of casting rollingmill is designed. Electro-hydraulic double-precision device is adopted in thesynchronized screw down system. The system realizes double-precisionadjustment of the roll gap, which both can meet the control precision and depress rapidly. A parametric feature library modeling system is developed inthe form of Dynamic Link Library (DLL) by using the secondary developmentfunction of Pro/ENGINEER, programming environment of Pro/TOOLKIT andVisual Studio.net2005. Parametric design of screw down system is achieved,and the system is serialization. The system has a friendly, intuitive interface ofthe dialog box, which contains a variety of different types of parametric featureprototype. The three-dimensional model can be generated only by entering thebasic parameter values. The modeling efficiency of Pro/ENGINEER is greatlyincreased.
