8.5 The production of U-shaped tabs and
mounting brackets
Before you start making U-shaped tabs, try bending a
pattern first. Check all sizes and make the necessary
changes.
Fig. 32: Finishing U-shaped tabs
Always move the eccentric anvil so that it is as close to
the bolt or bender as possible to prevent the material
from slipping.
If you want to extend the U-shaped tab, you will first find
out how much material you need for it. Now you have to
add twice the amount.
Example: If you want to extend the tab by 25 mm, you
must add 50 mm over the total length. The distance from
the eccentric anvil to the material end will only increase
by 25 mm. The other 25 mm are for the other end. The
bending machine has bending rolls of different sizes.
This allows you to bend different U-shaped tabs. Always
use rollers on the center bolt when working with a mate
-
rial thicker than 9 mm. Otherwise you could accidentally
bend the bolt. The material is stretched during the ben
-
ding process. This stretch is different for each material.
For this reason, we recommend that you test the stretch
even if you use this manual.
Make a note of the diameters of the bending rolls and the
dimensional deviation of the elongation. So you can save
time in a repeated production.
Fig. 33: Correct arrangement
Example 1
For a 9 mm screw with a length of 310 mm, the distance
from the eccentric anvil to the stop is 2.15 mm.

Example 2
For a screw with a length of 310 mm and a thickness of
12 mm, the distance from the eccentric counter-holder to
the stop is 1.15 mm.
