TOOL DEFINITION GUI

The tool definition GUI allows the user to assign the tooling and blank mesh required for setting up a particular draw simulation. Refer to Section 8.1.1.

In some draw simulations, drawbead utilization is required to provide better metal flow and prevent excessive wrinkling conditions. The QS/Draw enables the user to model drawbeads from the tool GUI as shown in Figure 8.2.1.

 

Figure 8.2.2 The Define Drawbead dialog window.

After clicking the DRAWBEAD button (Figure 8.2.1), the user can define drawbeads from the DEFINE DRAWBEAD dialog window (Figure 8.2.2a). The user can click on ADD to select drawbead line data. If no drawbead line data is available in the database, the user can generate drawbead lines by using the POINT/NODE option.

The default full lock force is calculated based on material thickness and tensile strength. The user must define the blank material and thickness accordingly prior to generating drawbeads. As shown in Figure 8.2.2n, the user can modify the percentage of drawbead lock force after the drawbeads are defined. In addition, the user can simply add or remove drawbeads.
