Two-Hand, Foot Control. The two-hand, foot method of press brake operation is unique in that it provides point of operation guarding, yet allows operator to form the part without interference from a guard. Unlike some systems, no additional set-up time is required.

When the press stops at the top of the stroke, the foot switch is automatically de-activated, requiring the operator to use the palm buttons once again to bring the ram down to its present position.

If the operator does not need to hold the part at any time during the stroke, the keyed selector switch may be turned to "hand only." Use of the hand buttons only enables the operator to cycle the press through one complete stroke without stopping. Similar to punch press work.

The press may be jogged at any time, but will stop when either the palm buttons or foot pedal is released.

Many safety devices are by-passed for set-up purposes. However, this system is ideal for set-up since the operator must use the two-hand, foot controls for set-up as well as production. At the same time, it will not create any additional problems during set up.

Operational Description:

  • Operator depresses the two run buttons and initates the press brake stroke
  • Operator must hold the buttons down and the ram descends at fast speed down to the 1/4" position above the workpiece. If the operator releases one or both run buttons the ram will stop automatically. If the control panel is keyed to "hand only" the ram will make one complete stroke. This is helpful if the press brake is used for punching, piercing, notching or blanking.
  • Select-O-Stop automatically stops ram 1/4" above the workpiece
  • If the workpiece is not already in die it may be inserted at this time
  • The two hand control or the foot switch is now re-initated and the press brake slow forms the workpiece and then returns to top stop at high speed. The press brake is then ready for the next stroke.

Select-O-Stop is a keyed function that is activated by the calibrated switch actuator which is mounted on the side of the ram. Select-O-Stop allows the operator to bring the ram down in fast speed to a preset position which is 1/4" above the material being formed and will automatically stop the ram. This gives the operator the opportunity to realign the work piece and then slow form the workpiece if desired. Select-O-Stop is a keyed function on/off on main control panel.
