Roper Whitney Sheet Metal Folders | Auto Brake AB1014K Kombi Series

Roper Whitney Autobrake Kombi Series

Kombi Autobrake

For over 40 years, Roper Whitney has been producing quality folding systems for a variety of markets. Building on that experience, the newest generation Autobrake folders integrate advanced wing bending design with the features that have made the Autobrake the choice of professionals.

The Autobrake combines automated bending of angles up to 145°, material clamping, and material support into a single CNC controlled system employing wing bending techniques. Manufacturing, service, and applications support are based in Rockford, IL U.S.A.

Benefits of the Autobrake System vs. Manual or Press Brake Bending are:

Reduced labor costs
Improved part accuracy
Reduced setup time
Minimized tool changes
Improved part quality especially on soft and pre-painted material

The Roper Whitney Autobrake is a plate and weldment steel construction, delivering superior performance and features in a simplified rigid design. End housings are a plate-type construction bringing drive components close together for improved stiffness and performance. Actuating mechanisms are secured in rigid mounts at the outside of the housings, allowing easy maintenance.

The unique rotating Kombi beam allows for straight tooling and Box and Pan tooling. It is a fabricated structural prism on which is mounted tooling to firmly clamp a broad range of materials, close hems, and withstand the forces generated by capacity forming operations. Machined into the Kombi beam 180° from each other are the attachment surfaces for the straight and box and pan tooling. Tools are attached to the Kombi beam with standard socket head cap screws. Grooves are provided to secure tools even while the clamping bars are loosened for adjustment. Rotation of the Kombi beam is powered by a brake motor driving a sprocket and roller chain mechanism.

Clamping and hemming are programmed. The upper beam is driven to program settings on both ends by a brake motor and eccentric drive of the beam with a connecting shaft. Clamping and hemming power is delivered to the clamp jaws by a series of spring washers to provide variable clamping pressures with a shock-absorbing end stop. This provides reliable clamping pressure regardless of material thickness. Integral to the upper beam are the ways with non-metallic gibing to guide and retain the upper beam within the end housings.

Part program operation and creation are accomplished on a pendant-mounted computer control, located at the right-hand side of the machine. Programs are presented in a logical organized manner similar to the steps used to create parts on traditional folding brakes, allowing an easy rapid transition to the Autobrake. The computer control can be rotated into position for best use, and can be positioned to the rear of the machine.

Programming Functions are:

Bend Angle
Gauging distance
Spring back compensation
Offsets for hem operations
Radius profile macro gauge
Programmable delay for back
Customer alpha/numeric part number
Open hem height
Open, closed, or teardrop hemming entering of part
Information screen for related data
Material handling instructions
Jaw opening
Programmable part counter

 

Optional Features For The Autobrake Automated Wing Bender Folder:

• 4" Tall Upper Beam Sectional Tooling
  • The unique Kombi beam is a fabricated structural prism on which is mounted
    tooling to firmly clamp a broad range of materials and withstand the forces
    generated by capacity forming operations. Machined into the Kombi beam 180¡
    from each other are the attachment surfaces for the straight and box and pan
    tooling. Tools are attached to the Kombi beam with standard socket head cap screws
    and grooves are provided to secure the tools even while the clamping bars are loosened
    for adjustment. Rotation of the Kombi beam is powered by a brake motor driving a sprocket
    and roller chain mechanism.
• Several Backgauge Configurations Including:
  • U-Shaped Backgauge Extension
    • The U-shaped 12? backgauge system is simply a right and left backgauge extension
      taking your total backgauge dimension out to 144". This option can be mounted on any
      61" backgauge and can also be added to machine already in the field.
  • Left Or Right Hand 12' Backgauge Extension
    • The 12' foot backgauge extension can be added to any 61" backgauge and will extend your
      total gauging out to 144". This feature can be added at any time and can be retrofitted to
      machines that are already in the field. The backgage extension can be mounted on either the
      right or left side but needs to be specified when it is ordered.
  • Complete 12' Backgauge
  • The optional complete 12' backgauging system has to be specified prior to ordering an Autobrake.
    This system consists of a complete backgauge table that is 12' in depth as well as 12' in width.
• 61 inch Sheet Metal Backgauge
  • 60" ball screw backgauge offering a larger backgauge
    depth as well as the capability to extend the backgauge to 10'
• Squaring Arm For Small Or Narrow Parts
  • A squaring arm can be added to any backgauge to help in gauging narrow parts.
    The squaring arm mounts on the side of the backgauge and allows the operator to
    use one or backgauge fingers to accurately gauge narrow pieces.
• Laser Scanner
  • The optional laser scanner is a programmable safety system that scans the entire front
    side of the Autobrake. This unit is mounted under the machine and offers more security
    than light curtains.
• Hardened Tooling
  • Tooling for the Autobrake can be laser hardened for more durability. This option is only
    recommended when all stainless steel or pieces with plasma cut edges are run on the machine
