ABSTRACT

Automatic draft machine is a kind of special machine, becoming popular in recent years. With the increase of the human cost and more attention enterprise pays to production safety and accuracy of draft, automatic draft machine has begun to gradually replace manual draft. This paper uses SolidWorks to design a kind of double guide rail draft machine, introducing comprehensive meaning and purpose of the double guide rail draft machine, stating the basic structure, basic principle, applications and problems of the double guide rail draft machine. By using computer aided design technology, finishing the modeling, assembly and simulation of the double guide rail draft machine.

In this design, by using a 3d design software called SolidWorks, to carry out modeling, machine assembly and interference checking of the double guide rail draft machine, by using the function of animation simulation and explosion figure, to show the mechanical structure and the draft process of the double guide rail draft machine explicitly, and according to the courses of undergraduate, to further complete the selection, installation and commissioning of motor, oil cylinder and sensors.

By the combination of modern three-dimensional modeling software and mechanical design, to provide a new and efficient method of product design and development, by carrying out testing, improvement and evaluation with the virtual prototype instead of the physical prototype, to achieve goals of shortening product design cycle, reducing the cost of development, improving the quality of the products and meeting the needs of customers and market
