How Does the Rotary Draw Bending Method Work and What Types of Products Can You Make?

Rotary draw bending is a cold bending method where the member is clamped to a rotating bend die and drawn around the bend die. The tailing tangent is held against the bend die by a pressure die, and the bend die rotates until the desired geometry is formed. A mandrel is often placed inside the member to restrain cross-sectional distortion during the bending process. Bends can also be formed with special draw-bending equipment where deformations are controlled by tensioning along the member axis. Rotary draw bending is commonly used to form small radius bends in smaller-size round, square and rectangular HSS members. Specific tooling is required for each member size, shape and bend radius; therefore, this method is best suited for projects requiring many identical bends. This bending method is primarily used in the machine and parts industry (Weisenberger, 2016) and for piping (Riviezzi,1984). The maximum degree of bend is 180°, but the minimum bend radii of round HSS is approximately 50% smaller than that of other cold-bending methods (Riviezzi, 1984).

Two New Rotary Draw Benders Aid Quality and Repeatability!
When striving to be the best, you can never settle and should always explore opportunities to improve. Albina adopts the philosophy of continuous improvement in all aspects of our company. We are ALWAYS looking to make improvements in everything we do. The most recent improvement we are committing to is with some of our bending equipment. We are purchasing two new bending machines to allow us to provide parts to higher quality standards and provide for better repeatability. The two machines we are purchasing are smaller rotary draw benders. The larger of the two machines will bend up to 3½” OD material while the smaller of the two machines will bend up to 2” OD material. We are very excited to bring these two machines to our already vast list of equipment.
