Piston 160 mm, Straightening speed up/down 25/75 mm/s, Daylight 550 mm,
Distance to column 620 mm, sensitive Straightening stroke via handlever with
turret-stop, Measuring device for accurate straitening via a lightbar
Horizontal Straightening Device Model HRW 25, Pressure 25 tons attached on right
hand side of vertical Press, straightening stroke 160 mm, straightening speed fwd/bwd
57/10 mm/s, designed as Pressbow which moves in both directions against a straightening
tool to avoid the turnovers of workpiece during straightening process, 4 tool posts front
and backside/left and right with a distance of 600 mm, Handlever for stroke movement.
Torsion straightening device for twisting the section material up to a power of 25.000 Nm,
Resistance Moment 69.000 mm³, twisting force max. 320 N/mm², workpiece glamping 320 kN,
mounted on left hand side of Press as a integrated unit. The left handed slide can be moved
approx.. 3000 mm and is equipped as the clamping station for the workpieces and the right handed
unit is for clamping and twisting hydraulically this workpiece up to 35 ° Display to see the torsion on a lightbar.For the crossmovement/loading of workpiece is a roller chain available
Straightening Bed for placing and for moving the workpiece towards to the straightening devices,
consisting of conveyor roller tables left and right on the press with each approx. 3000 mm length,
rollers can be lifted pneumatically for easier transportation. Between the two beds is a working
gap for the vertical straightening cylinder with two adjustable counter steadies with exchangeables
jaws. Mechanical measuring device to check tension of workpiece built on presstable.
