TWIN HEAD

Twin-Head Tube-Bending Machines

Twin-Head Tube-Bending Machines form two bends simultaneously and are ideal for high-speed bending of symmetrical tubular parts. They are typically used for Automotive Seat Frames, Handles, Furniture, and Frames of many descriptions and can be tooled to bend the following profiles:

  • Round Tube Or Pipe
  • Square Tube Or Rectangular Tube
  • Solid Rod
  • Flat Stock
  • Angle Iron
  • Aluminum Extrusions
  • Some Roll Formed Sections

Types of Tube Benders

Criterion Twin-Head Tube Benders are available in CNC and Non-CNC Types. The same bend head modules are used for both applications and are available in three standard sizes. The tube diameters listed below are the maximum tube sizes. The minimum tube size per tube bender is dependent upon application details. Please consult Criterion for your application.

  • Model 7500 Twin Head Tube Bender (0.75" [19.0 mm] Diameter)
  • Model 26000 Twin Head Tube Bender (0.25 – 1.50" [25.0 – 38.0 mm] Diameter)
  • Model 50000 Twin Head Tube Bender (2.00 – 2.25" [50.8 – 57.2 mm] Diameter)

Details About CNC Twin-Head Compression Tube Benders

Our multiple-axis CNC Twin-Head Compression Tube Benders come in 4-axis and 5-axis versions. A CNC Rotating Tube Center Clamp located between the bend heads provides the Plane of Bend axis. A 5-Axis CNC Twin-Head Tube Bender consists of the following axes:

  • Degree Of Bend-1
  • Degree Of Bend-2
  • Distance Between Bends-1
  • Distance Between Bends-2
  • Plane Of Bend

Twin-Head CNC Draw Bender

Another type of Tube Bender uses CNC Draw Tube Bending-Heads instead of Compression Bending-Heads due to "interference zone" and flexibility issues. A Twin-Head CNC Draw Tube Bender is typically used in applications where the tube length relative to the tube diameter is very long, and numerous bends are required. Bending this type of tube is not often feasible on a conventional single-head CNC Draw Tube Bender since the tube may distort under its own weight during the final part rotations.

Typical uses for this equipment are as follows:
 

  • Automotive Brake Lines
  • Fuel Lines
  • HVAC Lines
  • Airbag Diffuser Tubes
