Placke HQPB 4 60 to. x 1.550 mm

Machine is in as-new condition.

The High Quality Press Brake (HQPB) represents the top model of the Placke range of press brakes. The entire manufacturing process, from hydraulic cylinders to control cabinet assembly, is performed in-house. By combining state-of-the-art technology with many years of expertise in forming technology, the HQPB series enables precision bending at the highest level. Even the standard configuration provides a fully functional press brake. This package of safety, reliability and efficiency, together with user-friendly operation, allows us to meet the highest demands and tolerances in the bending process.

Machine Frame:
- Base machine constructed from S 355 N steel
- Side supports with 2 pressure pipes and an overhead oil tank, welded
- Above-floor design
- Coating (2-component structured lacquer), light grey (RAL 7035) and signal grey (RAL 7004)

Upper Beam:
- Press beam stress-relief annealed
- Depth of stroke measurement, reading head guided by ball bearing rails
- Separate Y1 and Y2 control, electronic monitoring of parallelism

Hydraulic System:
- Hydraulic proportional control valve with electronically monitored cylinder synchronization
- Solid steel cylinders with inductively hardened piston rod
- Low-noise internal gear pump

Punch Clamping:
- Upper tool holder system WILA, hydraulic clamping system, Type NSCL-II-HC, fully hardened, Maximum load: head bearing = 250 t/m, shoulder bearing = 300 t/m

Lower Beam:
- Narrow table incl. manual clamping strip, dimensions: 48 mm high, 70 mm wide
- Reinforced lower beam. Mechanical crowning compensation is structurally unnecessary.
- Single V-die holder (13x20)
- Working height: 1050 mm (with 55 mm die height)

Front Side of Machine:
2 aluminum support arms at the front, approx. 600 mm long, incl. 2 flip stops, measuring tape, and plastic wear strip. The support arms are adjustable via ball guides and height-adjustable from 55 mm to 100 mm die height using a slotted adjustment. The ball guide is milled into the lower beam.

Control and Regulation Technology:
