Virtual kinematic press & die simulation makes productivity predictable

Checking the clearance of die designs based on interference curves is a real time-consuming task in the engineering process. In addition, there are often other problems in engineering practice - the design of the part grippers and their mounting on the gripper rails is often done at the end of the design process. A further obstacle is often the lack of genuine interference curves based on the press line parameters. And even a professionally executed throughput plan based on clearance curves reaches its limits when additional movements are carried out in the die or on the gripper rail, e.g. when the part needs to be reoriented/realigned or flipped.

All these problems are not new, and they fall far short of exploiting the possibilities of design in 3D. It is therefore not surprising that considerable efforts are being made to eliminate these insufficiencies in the context of increased frontloading, by means of a kinematic and virtual collision analysis in 3D space.

Considering the machine, part, and tool movements already in the design process not only simplifies the design and thus shortens the design time but also directly links it to the press parameters and makes the die designer to work directly related to the stroke rate of the press. This is because the stroke rate of the press line is a direct derivative of the considered motions to check the clearance situation. Effects on the stroke rate can be seen during the engineering process and can, of course, be directly influenced by the design of the tools. This is a double benefit for all users of kinematic throughput tests.

Moreover, the overall process up to real dies set up on the press is even enhanced by the fact that the chosen settings represent an initial set of parameters for stamping equipment. This reduces the start-up time and thus the downtime of the equipment. Setters can fully concentrate on the finetuning of dynamic parameters such as the forming speed or the acceleration parameters of the transfer systems. In short - the overall process is more effective, and the result will be a higher production efficiency.

The video in this post shows the current state of my software development. Conceived from scratch, without having to take existing systems into account, the run-through simulation offers a new dimension of simplicity. It is fully tailored to the needs of clearance investigations in forming and designed to be applicable to all press manufacturers. In addition to the movements of the press line, from front-of-line systems to press and transfer, further movements are considered. These include, for example, pad and blank holder movements, movements of sliders in the lower and upper dies. In addition, movements generated by pneumatic actuators, which can be installed both within the die and on the gripper rail, are also taken into account.

The service of kinematic and virtual flow simulation includes the analysis of the part flow in the 3D space of your tool design. Results of the simulation are design recommendations and advice for the used standard components in the context of the used press as well as initial set-up data for the initial setting of the press line.

Benefit from the opportunities of this service and take advantage of this offer to optimize your new tool designs virtually and kinematically in respect of clearance and output or to assure successful relocation projects.

Take advantage of my expertise to support you in the from the stage of design and planning to the start-up of you dies on the press and thus ensure maximum productivity right from the start.

I look forward to receiving your message and will be happy to demonstrate the features and benefits for your tooling project.
