What Types of Indirect Extrusion are Supported by HyperXtrude?
HX supports two types of indirect extrusion presses.
- Moving container and ram.Here the die is fixed and the container slides over it. The setup is similar to direct extrusion. Before exporting the grf file please assign the ram speed to Z_Velocity on Billet_Container boundary. Next, edit the TCL/HX file and set the ExtrusionType to IndirectExtrusion.
- Moving die.Here the die is pushed into the billet, and it slides inside the container. Edit the TCL/HX file and change the ExtrusionType from IndirectExtrusion to IndirectWithMovingDie.
This will be automated in the next release of HX User profile.
The table below shows the input syntax for different processes.
| Input file | Variable | Direct Extrusion | Indirect (Moving Container and Ram) | Indirect (Moving Die) |
|---|---|---|---|---|
| C2E support | C2E support | C2E does not support. Manual Correction needed. | ||
| *.tcl or *.hx | pset ExtrusionType | DirectExtrusion | IndirectExtrusion | IndirectWithMovingDie |
| *.grf | Dummy Block | Inflow BC Z_Velocity = ramspeed | Inflow BC Z_Velocity = ramspeed | SolidFluid Interface Z_velocity = 0 |
| *.grf | Container Wall | SolidWall (U=0) | SolidWall Z_Velocity = ramspeed | SolidWall Z_Velocity = 0 |
| *.grf | Die Face | SolidWall Z_Velocity = -ramspeed | SolidWall Z_Velocity = 0 | SolidWall Z_Velocity =-ramspeed |
