4. To install the counter die, remove
the hitch pin and insert the counter
die in the opening in the counter die
mount until the 3/4” holes line up.
5. Now insert the hitch pin through all
the holes, reinstall clip on the hitch
pin with the engraved side of the
counter die facing up.
Material Layout
In order to create accurate parts, you will have to layout the material in flat form. First you will
need to determine how much material is used per degree of bend. Use the multiplier table on
Table #3 to determine the arc lengths for the die in use. Or use the following formula:
Alternate arc length formula:
Example: 6.0 clr x2=12 12x3.14=37.699 37.699/360=0.1047” per degree
0.1047x 90 degrees =9.425” of material used for a 90 degree bend.
Once the arc lengths are determined you can begin layout of the material using Diagram #1 as a
reference.
•
Diagram #1 shows a simple part bent on the same plane in the same direction.
•
Diagram #2 shows bending based off of a centerline in two directions.
•
For symmetrical bends, centerline bending is easiest.
•
For non-symmetrical bends, continuous one direction bending is best.
•
Another way to layout material is to draw them in a 2D computer software program like Auto
Cad. There are many free programs on the internet. In a 2D program you will draw the parts
centerline only with corresponding clr’s. Then you will be able to list individual segments of
the bent part. This data can be directly entered into the control.
