Pro/E-Based Design And Manufacturing Of Two-Roll Straightening Machine Roller Type For Bar

The production of the two rollers straightening has the advantage of the high precision and good quality, therefore, the two rollers straightening takes an important role in the straightening product. With China's metallurgical industry development, it is need a large number of straightening equipment put into production. This requires straightening machine production to form a certain scale and high quality of the production line. Straightening roller is one of the core parts of the straightening machine, so for the fast batch production of the straightening machine, it is particularly important that the straightening roller's integration degree of design and manufacture. With the development of science, especially the development of computer technology, computer has become an indispensable tool in Engineering. The application of computer design and manufacturing software can achieve a certain parts of the design and manufacture of integration (CAD/CAM), it not only improve the quality of the products, but also improves the efficiency of production design and manufacturing.This text is according to the theory of elastic and elastic-plastic of bar, analysis the principle of the two-roll straightening. In research this text use AutoCAD to calculate the curve shape of three curvature shape, and draw the out.Pro/ENGINEER is one of the maximal development systems which integrate CAD/CAM. It not only has three-dimensional computer evaluation product design and highly automated two-dimensional engineering drawing function, but also has the formidable project analysis ability, which make the finished products that people developed not only possess layout and appearance value, but also have project application value.This text is according to the Pro/ENGINEER that design and manufacture of 3D functions. It avoid complicated mathematical calculation, according to the three curvature inflection roll gap curve, using copy form exhibition method established the model of straightening roller. By the module unit of manufacturing, simulate the processing of straightening roller manufacturing, generate NC code.This text also designed the key components of two roller straightening machine—shaft of the straightening roll. Determined the other related parameters of straightening machine, and design the two roll straightening machine, finally.
