Controlling Twist: Top 7 Functions for Angle Roller

3d aluminum bending

Controlling twist is an important consideration when bending non-symmetrical sections of aluminum using an angle roller(profile bending machine). Some factors that can affect the twist of the section during the bending process include the material thickness, the radius of the bend, the angle of the bend, and the design of the profile.

To accurately control the twist of a non-symmetrical section during bending, profile bending machines for aluminum may incorporate a number of features, such as:

  • Rollers with special shapes: The rollers used in profile bending machines may have unique contours to match the cross-sectional shape of the aluminum section being bent. This helps keep the section centered and helps prevent twisting.
  • Adjustable guides: The profile bending machines may have adjustable guide rollers that allow the operator to fine-tune the placement of the aluminum section as it is being bent. This can help reduce twist and improve the accuracy of the final product.
  • Multi-axis control: Many modern profile bending machines have multi-axis control systems that allow for precise positioning and management of the bending arm or rollers. This can be particularly important when trying to control twists.
  • Variable-speed rotation: Some profile bending machines incorporate variable-speed rotation, which allows for more precise control over the speed of the bending process. This can help prevent the overloading and twisting of the material during bending.
  • Digital feedback: Digital feedback systems can provide real-time information on the bending process, allowing operators to make adjustments as needed to maintain control over the twist of the section.
  • Precision rollers: Precision rollers of section bending machines can help prevent twisting and deformation of the material during bending. This is particularly important when working with delicate or complex profiles.
  • Post-bending correction: Finally, some profile bending machines may include post-bending correction features that allow operators to make small adjustments to the twist of the section after the initial bend has been completed.

Non-symmetrical sections of aluminum have varying cross-sectional shapes, which can make them more prone to twisting during the bending process. If proper precautions are not taken to control the twist, it can result in an unsatisfactory end product that does not meet the desired specifications. To avoid this, it’s important to carefully select the appropriate profile bending machine and to use specific techniques, such as using a mandrel or roller leveler, to control the twist and maintain the desired shape of the bent aluminum section.
