This lesson describes the definition of a progressive die. In a progressive die, several operations are arranged in one toot and installed e.g. on a ram. The original simulation contains several operations. Due to the time involved, you will only define three cutting operations and three forming operations, i.e. six stations. As a further simplification, a rectangular blank having the width of a station will be considered as the initial blank instead of a coil (computing time).
Main Focus
Definition of individual operations
-Copying the existing operations
-Define Trimming
Execution of the simulation
Used Software
AutoForm-Incremental
Owing to the multiplicity of the tools and ait curves, the simulation has been prepared so that the corresponding geometry and the curves are already available in the simulation.
Open simulation pp_lesson_06.sim as follow:
Main window File > Open > Select a file > Directories: Select the folder
containing the f > File: pp_lesson_06.sim > OK
Close the Geometry generator.
All further specifications are defined in the Process generator.
Generating the input for the Simulation
Open the Process generator.
Main window Model > Pro< ss generator ... > Simulation type: Incremental
Operation setup > Auto-positioning/geometry stage: None > Tool setup: Cut > Gravitiy direction: Downwards > Sheet thickness: 1.35 > Geometry refers to: punch side > OK
In this operation define the first tools, the transport and insertion guide rails, as well as the first three cuts.
The black print pages have been completely filled with default values. However, the specifications should be checked prior to each simulation to see if they are valid for case at hand.
Complete the input for the simulation: Some entries are still missing on the pages; these are marked by red.
Process gen.
Rename the first operation:
Edit... > Edit Operation > Tag: > 10 > Set
Define Tools
First insert the Tools page in the Process generator:
Process gen. Add > A > Add tool > Default tool settings > Use default
settings > Add tool
Tools On the Tools page, define the tools. Enter the following data for the
lower transport bar:
tool 1 > Tool name > Name: bead_lower > Below Geometry > Reference ... > Reference tool geometry: bead_lower > Current geometry-stage: 2 - bead_lower - Part > Select objects Part > OK
Geometry > Blank contact (switch off) > Offset: > 1.35 > Columns > None
Now add the upper transport guide rail as second tool:
Tools > Add tool... > Add tool > Default tool settings > Use default settings > Add tool
tool.?. > Tool name > Name: bead_upper > Above Geometry > Reference ... > Reference tool geometry: bead_upper > Current geometry-stage: ' - bead_upper - Part > Select objects > Part > OK
Geometry > Blank contact (switch off) > Offset: > 0.00 > Columns > None
Defining the Initial Blank
Go back to the Blank page.
On this page, define the initial blank. As simplified metal strip use the pre-defined rectangular blank. The blank is available as in af format:
Blank Blank> Outline > Import... > Import curve(s) > Import file > File
format: af > Directories: Select the directory containing the file > Files: pp Jess on_06_b la nl<_ outline, af > Vertices > Use all > OK > Select curve > Pick curve > Pick or select from list: urve 14 > OK
The blank is situated on the lower transport guide rail.
Position > On: 10_bead_low.
Properties > Material: > Import... > Select file > Directory >
Furope/Cold?Rolled_Coated > Files > DC06_EZ.mtb > OK > Disclaimer > OK
