Development of CAD Systems for Screw Blades
Screw conveyors deliver materials in desired quantities in a steady and continuous manner, and are widely used in factories and mining. The design of large multi-blade screw conveyor involves complex calculations and large repeated workload, and is poor in accuracy and efficiency. With modular design as the guideline, using object-oriented programming language VB6.0 as the developing tool, and based on the platform of AutoCAD, this article discusses the development of a user-friendly CAD system that allows arbitrary division of the outer vortex. Practice has proven that this simple and pragmatic system largely improves the design efficiency and precision.
