Our Accomplishments for your Benefit
Dimensionally accurate and evenly bent chain incontinuous operation
Robust machine design for the production of high-strength
chains over a long period of time
Safety devices for protecting machine parts and tools

KEB 3.1 bending tools

Mode of Operation
The wire is drawn in from the wire coil. It is then straightenedin two levels, notched and cut at intervals according to theblank length. In the first bending station, the blank is prebent
around the two-part bending mandrel.
The prebent chain link is transported to the second bending
station where it is finish-bent into the chain. In a third station,
the chain link is calibrated to the correct width.

Design Features
3-shaft system
Smooth machine running
Operations (forward and backward stroke) positively
controlled via curves.
Safety devices for wire infeed, blank stop, clamping on thebending mandrel.
Clutch-brake combination with fast reactions
Wire infeed gripping tools are pneumatically actuated.
(KEB 3.1 - KEB 7.1) All other motion sequences aremechanically controlled.
Wire infeed and gripping, notching, and closing the turning
tongs occurs hydraulically. (KEB 8.1) All other motion
sequences are mechanically controlled.

WAFIOS KEB.1 – Chain Bending Machines

Application
KEB.1-series chain bending machines are used for the cold
bending of round steel chains. Wire material discharge
from the wire coil. The bent chain can then immediately beelectrically welded on a separate machine.
