QForm has been designed to make your work easy. It has a simple project-oriented interface that allows you to easily try variations of your technology to quickly find the best solution. Each variation can consist of several consecutive forming blows with heating/cooling between them. The same technological chain may consist of both 2D and 3D forming operations and a simulation can be set up to run through several blows in different dies or within the same die. The user can interactively position the billet in the dies and/or rotate it between blows and the “gravity option” allows finding natural stable position of the billet on the complex die surface. Between simulations of successive blows the flash can be trimmed and a hole can be pierced in the workpiece. If necessary, the workpiece can be separated into two parts for individual simulation each of them.
EASY TO USE:
Set up of a simulation is very easy and fast. The source data are prepared in just a minute or two by means of self-explanatory Data Preparation Wizard. QForm has many features that allow the user to quickly identify and solve a variety of problems and to maximize the benefit to your company. Click here to see what is needed to set up a simulation.
The material database includes several hundred steel grades and non-ferrous alloys. The equipment selection includes mechanical, hydraulic and screw presses, hammers and specialized machines such as electric upsetters. The user may edit or add/import their own data.
INTERFACE WITH CAD:
QForm works well with popular CAD systems like SolidWorks, SpaceClaim, Pro/Engineer, Solid Edge, and Mechanical Desktop. For 2D simulations, the die and billet geometry are imported via DXF files (*.dxf). For 3D simulations, QForm works with step (*.stp) or iges (*.igs) files that retain the original geometrical entities generated by the CAD system. This means that there is no reduction of accuracy of the geometry that is used for the simulation. Other simulation packages still use stl format geometry that reduces the surface of the geometry into a course surface mesh that loses detail and important information regarding the original geometry. With QForm, the geometry that is used for simulation is of the highest accuracy.
COMPLETELY AUTOMATED SIMULATION:
Once setup, the simulation runs automatically without the need for the user’s intervention and the results are visible concurrently with the running simulation so you can spot problems immediately without having to wait for the end of the simulation. The mesh generation is fully automatic and the adaptive self-controlled algorithm keeps optimal mesh density distribution during the entire simulation. This unique feature provides high accuracy of the results regardless of user’s expertise in F.E.M. QForm uses a non-uniform mesh so the mesh will be very fine in areas of detailed deformation, and course in areas where there is little deformation taking place. This increases accuracy and reduces time required for simulation. The mesh can also be set to be adaptive for velocity, strain and/or temperature.
Partial simulations. The use of segments is useful to speed up the simulation of complex 3D parts that have some symmetry and can be simulated as half or quarter section or as a pie shaped segment as small as 15 degrees. This means that the simulation will be significantly faster, and very often more accurate because the program can assign more mesh over a smaller volume. QForm can utilize two kinds of symmetry:
- Reflective symmetry is where the whole part can be made by mirror image reflection of some section of the whole. Such as parts where one half is the same as the other half or for parts with radially symmetric 3D components. Reflective symmetry is relatively easy to handle since the program considers the cut plane as a linear plane.
- Rotational symmetryis when the whole part can be made by rotating the segment around some central axis. Rotational symmetry is more complex to perform than simple reflective symmetry since the plane must flex and bend based on forces applied from the other side of the segment. QForm handles this complex process very accurately. Rotational symmetry can be useful for symmetrical parts with some non-radial 3D components or for nested platters.
