Advance/Pinch Retract Assembly
The advance/pinch retract is used in Europe on upacting press brakes. It
signals the gauge to retract to its programmed retract dimension when the
ram or bed reaches the point at which the upper tool pinches the material.
Note
Enable Retract at Pinch with these keystrokes: Funct, 707. Set to 1.
(Set to 0 to disable.)
Advance to the next station occurs when the limit switch on the
advance/pinch retract is pressed and then released. Retract at pinch point
occurs as soon as the switch is pressed; therefore, it is very important to
adjust the cam so that a retract can only take place immediately after the
material is pinched. The station will not advance until the ram is on its
return stroke.
Following are directions for assembling and mounting the advance/pinch
retract to a press brake.
