System of projection of draw dies on forming

machine of double operation

Sergey FominThe engineer - designersa.fomin@mail.ru

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.

The positive sides from application of system is:

Maximizes productivity through automation design Maximizes 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 2D It 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.

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 ).

Input data*

Model of draw operation

Contour of preform

Punch profile

The coordinate system defining direction of operation

Technological constructions

Model for the lower working parts (lower binder)

Model for the upper working parts (punch and upper draw die)

Work in system

The definition of parameters of the project:

- The name of the project

- Placement of the project on a disk

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.

Work in systemThe 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.

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.

Work in system

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.

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.

The user adaptation of the project

Editing of templates of working parts by the user we shall consider on an example of a punch

The user adaptation of the project

Make a part with a mask of a punch displayed.Defined with a standard size of a directing plate, and also their amount.

Punch profile

The user adaptation of the project

Plates directing load as components concerning an absolute coordinate system.

The user adaptation of the project

Plates directing are positioned, concerning a punch, by standard means of system.

The user adaptation of the projectPositioning of plates directing on height, concerning a plane of support of a punch.

In a context of assembly make plates by a working part.

Automatically the geometry of a punch in the locations of plates (support platforms, holes under fixture are attached, the thread is displayed) varies.

The user adaptation of the project

Defined with a standard size of a elements for transportation, and also their amount.

The user adaptation of the project

Elements for transportation are positioned, concerning a punch, by standard means of system.
