Tube bending machine Faq
Often today, you may not have actual part prints available to confirm material size and dimensions. A measuring device such as vernier calipers can be used to gauge the material’s outside diameter (O.D.) and inside diameter (I.D.), which will enable you to confirm necessary dimensions and make simple drawings.
Knowing the material’s true dimensions is key to selecting the proper machine and tooling for your application. Pipe sizes are measured by I.D., with wall thickness referred to in terms of schedule. Tube sizes are based on O.D., and wall thickness is referred to in gauge sizes.
When purchasing tube for your job, remember that the cheapest isn’t always the best. Bending tube or pipe of poor quality material often leads to poor-quality bends, higher rates of scrap, and possible breakage. Even the best machinery and tooling won’t overcome poor-quality tube material.
Material grade affects the tooling selection and composition; make sure the tooling is supplied to your material specifications so it doesn’t conflict with the material to be bent. As an example, stainless tube can conflict with a steel counter bend die.
When making a decision about material for your application, consider application strength requirements, appearance and quality, and centerline radius specifications. Ask your steel supplier for the material specification to ensure the material is appropriate for bending.
This may sound simple; however, it is not if you are not given prints and are asked to reproduce parts from sample pieces.
Rotary draw bending tooling usually is designed to accept a maximum bend angle of 180 degrees. When selecting bending machinery for your application, be sure the machine program or system allows for slight overbending to compensate for springback during the bend cycle. Selecting a bending machine with a programmable bend angle setting can provide high bend accuracy and ease of use.
Degree of bend also affects bend quality. When working with a new material, try making two test bends—one at 45 degrees and one at 180 degrees. You may see slightly different results in the workpiece, because greater bend angles produce more wall thinning and deformation in the material.
