SPI Sheet Metal for Inventor - 专业钣金展开软件

SPI - Sheetmetal Inventor
Design and Unfolding of complex Sheet Metal Parts with Autodesk Inventor
Features and Benefits

Together with release 10 of Inventor new releases of "SPI Sheetmetal Inventor" and "SPI Ducting Inventor" are available. SPI - Ducting offers a new component "Round to rectangular with inclination"
The solution
SPI - Sheetmetal Inventor is 100% integrated with the current Inventor solution. SPI enhance the basic sheet metal features of Autodesk Inventor. Unfoldings of complex sheet metal parts are calculated in seconds. SPI - in just a few seconds - leave a flat pattern transferable to e. g. laser or punch CAM programs and pressbrake control systems (special interface for Delem and Cybelec included) and to bending simulation software.
Advantage
SPI - Sheetmetal Inventor provide designers and manufacturers dramatic improvements in the process for ready to manufacture products. The result is significant cost savings and shorter design cycle. The initial selection of the manufacturing capabilities ensures that only the materials, tools and process available are recommended to the designer, avoiding rejection on non-manufacturable parts and the resulting rework.

The automatic flat generation provides fast, accurate flattening of 3D sheet metal parts to create the complete 2D flat information needed.

Fetaures and Benefits

SPI - Sheetmetal Inventor provides a variety of efficient design tools for sheet metal design. Especially the design of sharp cornered models - without the need to apply reliefs - is available.

A new command creates a planar base sheet from any closed profile. This command provides the user with material data and suitable thickness' values from the SPI material management. (1)

SPI also provides a command to create a "sharp cornered flange". The flange is defined by dialog-box-driven parameters which makes it easy to create the shape in one step. (2-3)

Another command creates a "sharp cornered sheet metal profile" from an open contour. The used material data and the thickness are selected from the SPI material management. (4-5)

With SPI it is possible to create associative unfold views in an Inventor drawing document. After any model change the corresponding SPI unfolding is updated automatically. (6-8)

The creation of it can be started from an Inventor drawing document. Here one selects the desired 3D part and the position of the unfolding view in the 2D drawing document. It is possible to have multiple unfold views for the same, or different parts in one document. Furthermore it is possible to create an associative unfolding within a design sketch of another 3D part. This sketch can be used for further modeling.

Furthermore SPI provides a library of punch and stamp tools. With the new SPI tool manager it is guaranteed that only tools are applied which are available for manufacturing. (7)

Even the unfolding of bending zones, that are "sharp cornered" on the inner side and have an outer radius depending on sheet metal's thickness is possible. This is relevant whenever imports of STEP files from other CAD systems occur (9).

More Examples


Pipes, which have non perpendicular cuts can be unfolded without any problems. The unfold shape shows the inner and outer contour of the cut.
   
  

The unfold shape of cones, even with axes is generated in seconds.
   
  

No unfold problems with conversions from polygon to circular.
