2. The Note
• This system was developed for projection
of dies which working parts are made on
cavityless casting.
• The equipment (forming machine ) on
which dies are designed should be strictly
double operation, i.e. have internal and
external slide blocks.

3. The positive sides from application
of system is:
• Maximizes productivity through automation designMaximizes productivity through automation design
process.process.
• Automation of tedious and time consuming tasks.Automation of tedious and time consuming tasks.
• It is much easier to visualize the 3D model than on a 2DIt is much easier to visualize the 3D model than on a 2D
drawing.drawing.
• Significantly shortens the design time.Significantly shortens the design time.
• 3D modeling is more accurate and useful than with 2D
design.

4. Requirements shown to
operation in system*
• The user should know a base training course on work in
system Unigraphics (the nobility of a basis of modelling,
drafting, and work in a context of assembly).
• The user should have an experience of a die design.
• Presence of a database of standard elements applied in
die design.
• Presence of a database of equipment (forming machine ).

5. Input data*
Model of draw
operation
Contour of preform
Punch profile
The coordinate system
defining direction of
operation

6. Technological constructions

working parts (punch and
upper draw die)
Zone of
technological
constructions

7. File of a part with the prepared
input data *

8. Work in system
The definition of
parameters of the
project:
- The name of the project
- Placement of the project
on a disk

10. Work in system
- Definition of layout of a die (escort
with a picture representation)
- Choice of the equipment (forming
machine )
- There is an opportunity of a
choice of presence of plates of fast
fastening
- Choice of a standard size of
directing tiles in a zone of a
direction of top of a dies concerning
a bottom.

12. Work in system
The menu of a choice of
geometrical data for
operation of system
The high-altitude size (БАЗА) describing
position of model of draw operation in a cavity
of a die on height is defined
There is an opportunity of inspection of the
selected profile for their self-intersection.

13. Work in system
The menu of a choice of geometrical data
- Choice of data for the upper working parts such as a punch, a hold-down tool
(upper draw die ).
- A choice of data for the lower working parts such as insertion, an a matrix
(lower binder).
- A choice of data for lead of a contour of preform.
- A choice of data for lead of a punch profile.
- A choice of data for lead of a inside hold-down tool.
(by option)
- A choice of data for lead of a contour of insertion.
(At presence of an insertion in earlier defined layout)
- The choice of a coordinate system, axis Z which characterizes a direction of
draw operation.

15. As a result of
operation of system
will be received
assembly part of a
draw die which will
consist of templates of
components which
have been defined at
a stage of layout of a
dies.

33. The user adaptation of the project
• The further development cycle of the project is
the analysis and editing of templates by the user.
• The analysis and editing are made by standard
means of module " Modeling " UG.
• At the same stage the user adds the standard
and normalized details in the project.
• There is an opportunity to add original details.
These details should contain in original parts files,
is in a directory with the detail design, at a top
part file of the project to be present as separate
components.
