K-Series Press
K-SERIES AT A GLANCE APPLICATIONS
  • Custom tonnage and bed length configurations are available
  • 2 cylinder design
  • 100 - 3,000 tons
  • 8' - 30' standard bed lengths
  • Tandem designs for long part bending
 Medium to Heavy-Gauge Bending
The K-Series Hydraulic Press Brake offers a proven design up to the challenges of tough, continuous service. Numerous standard and optional features include CNC controls, higher speed power units and manual or CNC-controlled heavy-duty back gauges.

STANDARD FEATURES

  • interlockRigid, Interlocked Design assures absorption and uniform distribution of forces in capacity operations. Heavy steel plates are utilized for the ram, bed plate and extra deep side housings to resist deflection.
  • bedPre-Crowned Beds are precisely machined for bed deflection compensation.
  • ramRam Guiding System consists of heavy-duty, non-binding guides that maintain contact with extra long, hardened steel slideways through the stroke range.
  • modular-stacked-valvesModular Stacked Valves are machined to provide maximum accuracy and special pressure and directional control characteristics. Valves are designed for long, rugged service with minimum maintenance.
  • cylinder pistionCylinder And Piston are heavy, cast single-piece domed cylinders to eliminate high stresses and potential leakage areas. Pistons and rods are one-piece, wear-resistant, Class 40 castings; bores are honed and polished to 16 micro inches.

ADDITIONAL STANDARD FEATURES

  • Tonnage control and non-overload relief valve system
  • Automatic decompression system
  • Temperature compensated amplifier level control

OPTIONAL FEATURES

  • content placeholderPlate cell. Optional laser bend alignment system, plate supports an electrically driven plate positioning system eliminates the need for operators to manipulate the plate by hand.
  • power unitHigher Speed Power Units. Three speed power units are standard on press brakes of 500 tons and higher, and are also available as an option on smaller tonnage K-Series brakes. Options include Rapid Advance (no tonnage), Fast Press (partial tonnage), and Normal Press (full tonnage) cycles.
  • content placeholderMedium, Heavy-Duty Powered Backgauges (manual and CNC-controlled models).
  • content placeholderPart Extractor. Electrically-driven, chain-driven extractor system moves along the lower tooling to remove a formed part that either cannot be removed from the front of the press brake or is more easily removed by sliding it out of one end of a tandem system.
  • content placeholder
    Plate Manipulators. Electrically-driven, rigid chain-driven plate manipulators installed in front and behind the press brake bed provide "hands-off" sheet manipulation.  Joystick controls incorporated into two-hand controls allow operators to maneuver the sheet to the desired bend location.
  • content placeholder
    Laser Bend Alignment (Tandem Systems). Two laser line generators — one at each end of the tandem system - project a visible line at the centerline of the installed tooling. A blank with the bend lines marked is moved into the press brake until the mark and the visible laser line are aligned and the press brake is cycled to accurately complete the bend. An optional center-mount (removable) laser line generator is available when a single press brake of the tandem system is to be used.

OTHER OPTIONAL FEATURES

  • Lengths up to 45' in a single press brake
  • Back Travel Over-Ride
  • Foot Switch
  • Deeper Throats
  • Increased Open Heights and Longer Strokes
  • Wider Platens and Angle Brackets
  • Heavy-Duty Ram Inserts
  • Horns
  • Multiple Depth-Stops
  • Oil Coolers and Heaters
  • Multiple Control Stations
  • Light Curtains
  • Automated Centralized Lubrication Systems

Consult factory if your application requires machine dimensions, speeds or flush floor installation not shown in the table above.

Notes:
(1) Machine length (L) to be specified by customer; (2) Distance between housing without horns is machine length (L) minus the dimensions shown (Example: K400-14' bend length. The between housings dimension is L=14' minus 19½" =12' 4½"); (3) A slot in the floor is required to clear the bed plate on small machines over 12' length and all large machines; (4) Models 500-tons and larger require below grade support for side housings.
