To simulation the forging of a round product, due to axial symmetry, it is recommended to solve a 2D axisymmetric task, the estimated time of the project with this approach can be ten times less compared to 3D simulation. Below is a basic example of simulation 2D axisymmetric task.

1.Click Create new process
2.In the tab Operation select Operation type - General forming, With thermal process and Problem type - 2D axisymmetric. Click Forward
3.In the tab Geometry click Load from file and specify the path to the geometry file C:\QForm UK\12.0.1\geometry\disk_2D\disk_2D.dxf. The uploaded geometry will appear on screen. Click Forward
4.In the Workpiece parameters tab you need to set the material and workpiece temperature. Click next to Material[Select...]
In the database window that opens, select the material Steels\Carbon steels\C22(1-0402) and double click on it, after that the material will appear in the tab Workpiece parameters
Set the workpiece temperature to 1200˚C. Click Forward
5.In the tab Tool parameters the drive type, temperature and lubricant must be select for each tool. To be noted that in this example Tool 1 - upper tool, and Tool 2 - bottom tool. Opposite Drive-Tool 1 click [Select...], and the equipment database window will be opened. Choose equipment Standard\Mechanical press\6.3MN and double click on it, after that the selected drive will appear opposite Drive-Tool 1
Tool 2 - fixed, and it acts in the direction of the OZ axes. Opposite Drive- Tool 2 click [Select...] , in the equipment database window , select Fixed drives\+OZ and double click on it, the selected drive will appear opposite Drive- Tool 2
Opposite Lubricant click [Select...] and double click to set lubricant Hot forging/Steels/Graphite + Water (graphite-water). Lubricant will appear immediately for all tools.
Next to Material click [Select...] and double click to set the material L6HRC42. The Material will appear immediately for all tools. Opposite Temperature set tool temperature 200°C.
Click Forward
6.In the Stop conditions tab you should set final distance between the tools. Click Distance. After that, specify the value of the final distance (3 mm). Click Forward
7.In the Boundary conditions tab all remains unchanged. Click Forward
8.In the Blows tab set the cooling in air and in the tool. Click Forward
9.In the Simulation parameters tab all remains unchanged. Click OK
10.Click on the button Simulation
, and the program will ask to save the project. Give the project a name and click yes. The simulation will start after that.
