Research on Parametric Integration CAD System of Sheet Metal Forming Hydraulic Press

The serial design theory was used to analyze and calculate the main components of sheet metal forming hydraulic machine,identify the key parameters of its component parts, establish the size parameter library of the structural characteristics of the parts and modularization thought was adopted to research parametric CAD intelligence design system of sheet metal forming hydraulic machine. By inputing the key parameters into the software system, the three-dimensional and two-dimensional product drawings of the different types of sheet metal forming hydraulic machine were automatically generated, and the strength and stiffness of critical components was automatically calculated. The experimental result expressed that the design time can reduce to 1 hour from 5 days through the CAD system, and the FEA optimal analysis can be performed, the 3 demension model and 2 demension design can be built automatically.
