Abstract
The graduation project is the design, the main task is the design of the chain drive mechanism on the mechanical structure of the cooling bed, lifting chain, lifting bodies, all kinds of support. The topics include the following:
In a first step, a simple statement of the cooling bed status and development. Cooling bed, the quality of steel products as an important part of modern industrial production plays a vital role. Then introduced the cooling bed classification, including reciprocating multi-claw type cooling bed, chain cooling bed, walking beam cooling bed, flip the cooling bed, swing-type cooling bed, roller-type cooling bed, as well as a variety of cooling bed features. The second step first introduced to position of the cooling bed, focuses on lifting chain part. The third step is based on the known parameters, the design of mechanical structures, mechanical analysis, motion analysis. Check calculation of the ponents. The fourth step of the use of the Auto Cad2010 Engineering Drawing, and check drawings error, analyze the cause of the error to be rectified.
The purpose of this subject is graduated through this design, all aspects of steel production line, familiar from the iron and steel smelting to rolling production of these mechanical devices. Deepen their understanding of the factory.
Key Words:cooling bed, lifting chain, chain drive, the Auto Cad2010
