For a tube bend that is not parallel to one of the planes of the drawing special views must be added to show the bend and the angle of the view will need to be defined.Īnother option is to set up a tube bend chart which actually defines the way a CNC tube bender will process a part. The preferred method to dimension the part is to show the straight lengths tangent of one end or bend to tangent of the bend follow by the CLR for the bend and the bend angle. This is the bend radius measured at the centerline of the tube half way between the inside radius and the outside radius. Tube bends are specified using the centerline radius (CLR). Some tube can be flared out to a much larger diameter, expanded or flattened without cracking depending on the tube specification such as SAE A513. Each process has its own cost points and attributes. Often DOM Tube is pressure tested and certified for high pressure service. DOM tube is made from strip, then welded and finally drawn over a mandrel and often through a die to smooth out the weld seam and precisely size the OD and ID. Close tolerance diameters or tube with a very heavy wall for the required diameter may be Drawn Over a Mandrel (DOM). Tube can be rolled up from flat strip and welded or extruded. Tube material (steel, stainless steel, aluminum, other) must be defined as well as the preferred manufacturing process. Tubes are defined by Tube OD and Tube Wall thickness while pipe is defined by ID and a scheduled gauge of wall thickness. This can be done in several ways but using a consistent drawing standard will benefit your suppliers and insure you receive consistent quality. The initial step in determining a tube bending process is to define the part. Mandrel bending is a special application of rotary draw bending when bends have a small radius or maximum tube roundness must be maintained in the bend. The different tube bending processes are rotary draw bending, crush bending, and roll bending. Each process has its own strengths and economics that must be considered.

Jaw Sets can be custom created for most benders, including: Eaton Leonard, Pines, Keins, Chiyoda, MiiC and others and can be made in any size, to fit most tubes or extrusions.

With our patented Dura Link® Universal Flex Mandrel Linkage, innovation has finally come to ball mandrels. Linkage hasn’t really advanced since the 1950’s.

Mandrels are another essential tool for the five-part tube bending method (bend die, clamp die, pressure die, wiper die, and mandrel) when maintaining the "ovality of a tube is essential. This process are used when the "ovality" of a tube needs to be maintained.

Wiper Dies are required for a five-part tube bending method (bend die, clamp die, pressure die, wiper die, and mandrel). The pressure die is used to apply pressure to the tube from the radius during the bending process. Pressure Dies are the third set of basic tools required for tube bending. The clamp die secures the straight section of the tube during the bending process. (Read more)Ĭlamp Dies are the second set of basic tools required for tube bending. A bend die is used to establish the radius in the bending operation. Tube Bending Concepts creates customized versions of the following tools.īend Dies are one of the three basic tools for tube bending (bend die, clamp die, pressure die). There are, however, certain types of products that are essential to the tube bending industry.
