Precision drawbenches are always used when the application can be
covered for economic or technological reasons with a combined drawing machine.
This is the case, for example, when special profiles, hollow profiles
and tubes with plugging are to be produced.
Drawbenches can be operated as single systems or in connection with
saws, shears, straightening machines, chamfering machines etc. as a production
line.
There are
1. Chain-track drawbenches,
2. Hydraulic drawbenches and
3. Drawbenches with rack and pinion drive.
The decision on the drawbench drive depends on the production demand.
The photo shows an example of the drawing slide of a drawbench, which
runs precisely on the linear guide and which is moved by means of a double
chain.
This allows a precise, jerk-free pulling.
The possible pulling forces are up to 1500 kN.
The triple-die drawbench allows simultaneous drawing of three bars
(round or profile) or tubes.
Simultaneous processing enables a threefold faster work process.
This is particularly advantageous for larger lots.
