Special Tube Bending Machines
Even with a large selection of standard Criterion Tube Bender designs, it is sometimes necessary to design a "special" Tube Bending Machine in order to provide the optimum application solution.
Applications that may require a specially designed Tube Bender usually have one or more of the following characteristics:
- Very large radius
- Very high volume
- Unique material spring-back vs. part repeatability requirements
- Complex part design with multiple "design interference" zones
- Requirement for unique material handling of part in automatic machine
Special Tube Bending Machines are often constructed by utilizing standard "bend modules" that are derived from Criterion's standard Tube Bending Machines.
The following photos and related videos listed below show a few special Tube Bending Machines that provided practical solutions to our customers' applications.
In-Line Transfer Tube Benders
This 2-Machine, 1-Operator Work Cell’s operations include drill gage hole, bend sweep, and notch both tube ends.
This special bender is constructed using these standard modules: Tube Magazine and Feed Unit, Model 26000 Bend Head Modules, Powered Slides, and Pick & Place Transfer Units.
This press bender forms large radius bends on 2" diameter tubing and is adjustable for variations in material spring-back.
This special bender automatically measures bends in aluminum extruded I-Beam and makes corrections until the bends are within tolerance.
Criterion also provides in-line multiple station transfer Tube Benders that utilize either compression or draw bending heads. The type of control [CNC or non-CNC] utilized depends upon the application.
This 5-Station In-Line Transfer machine includes 4 Model 26000 Bend Heads mounted in 2 different planes.
