 Simplify progressive-die design

VISI-Progress for progressive-die design lets users generate a flat-part blank by unfolding a 3D model step by step, deciding which bends are opened at each step and the opening angle value. Each intermediate model corresponds to a separate station in the completed tool.To get more news about progressive stamping, you can visit tenral.com official website.

These modules work together through one interface to handle design conceptualization, tool building, modifications, and manufacturing processes.

The VISI-Progress module operates with the core module for the design of progressive dies. It works like this: designers or toolmakers import the 3D model of a part to be made and unfold it manually or automatically to generate a flat part blank. The program guides users in determining the forming progression and placement of stations for the progressive die. The software then lays out the formed strip, with all necessary punches and forms.

For example, we designed a die to make a part with two 90° bends. The material thickness dictated that bends required separate stations for forming. One station in the completed tool bends the part from flat to 45° and the next to 90°. So we manually unfolded the 3D model, deciding which bends are opened at each step and the opening angles (in this case, 90, 45, and 0). This developed separate, intermediate 3D models for each bend and the flat blank. We then took the separate parts and combined them into a 3D model of the complete formed strip. Next, we input stock width and progression, or how far the material is fed to the next station, and the software modified the formed strip to those dimensions.
The program guides users in determining blank layout for optimizing material usage. For instance, users can rotate the part shape and the system reports the percentage of scrap for each rotation. This makes it easy to select the setting that most efficiently interlocks shapes.

In addition, the software has many useful tools for repairing surfaces and solids that ma have been "damaged" when their part files were imported. This helps follow a rule we learned from the beginning: good data input yields good data output.

Creating 2D views of the solid is also easy and automated. Users can pick a detail and select which views they want shown (for example: top, front right side, and isometric). The software creates the new views in seconds. And showing a customer a view of the form station is done easily by "slicing" through the 3D-die design. For instance, if the section line goes through a screw and a hole, the program displays half of the screw, hole, and form. And when there are parts within parts, the software displays the nested parts. This gives users a better comprehension of a design because users can see hidden parts and how they fit together.
