Based On Secondary Development Of Pro / E Y-type Three-roll Mill Parametric Design

The Y-rolling mill is a120°three-roll rolling mill. The mill was evolvedfrom steel pipe tension reducing mill in the1950s. Three rollers are arranged inthe form of mutual forms a120degree angle, roll is in a disc shape. The mill hasthe advantages of small volume, light weight, compact configuration, and it doesnot need lifting platform, roller, tipping machine and other auxiliary equipment,and it is less investment, fast construction, high production efficiency. The millused for nonferrous metal and alloy which has small rolling section, largedeformation resistance, high wide exhibition, small temperature range forprocessing at present. Products include copper, brass, bronze, copper-nickelalloy, titanium, aluminum, nickel and nickel alloys, etc. Because the structuralsimilarity of the Y-rolling mill is high, it is very suitable for parametric design.Pro/ENGINEER software is a parametric design software which has thefunctions of3D modeling,2D drawings, assembly, and dynamic simulation.This paper uses Visual Studio2005to Pro/ENGINEER4.0for secondarydevelopment, utilizes the correlation function provided by Pro/TOOLKITdevelopment tools, uses database technology, combines the relevant powerparameter to computer-aided roll pass design(CARD), utilizes synchronous andasynchronous development mode,finally accomplishes the parametric designsystem of the Y-rolling mill's important parts, realizes quick generation of theY-rolling mill to meet the market demand for its various types.This paper uses pass parameters and related data calculated bycomputer-aided roll pass design system, utilizes the finite element software,establishes finite element rolling process, analyses the numerical simulation,compares the field data, verifies the validity of the pass system, finally obtainesthe stable rolling process parameters, provides new ideas for future adjustmentof process parameters.
