Rotary Draw Pipe & Tube Benders - Mandrel Benders
Winton Machine builds all types of rotary draw tube bending machines. With or without a mandrel, these machines make precision bends in a single work piece.
Rotary draw tube bending utilizes tooling or "die sets" which have a constant center line radius (CLR). Rotary draw benders can be programmable to store multiple bend jobs with varying degrees of bending.
Winton offers CNC Rotary Draw Benders that are either controlled by a PLC or by a Windows Professional Operating System. Rotary draw benders are the most popular machines for use in bending tube and pipe. Winton Machine’s three axis tube benders are designed for precision bending applications in a wide variety of industries such as HVAC, aerospace, automotive, and the medical industry.
CNC rotary draw bending machines can be very complex and use sophisticated tooling to produce severe bends with high quality requirements. The complete tooling is required only for high-precision bending of difficult-to-bend tubes with relatively large OD/t (diameter/thickness) ratio and relatively small ratio between the mean bending radius Rm and OD.
The pressure die is useful to prevent excessive thinning and collapse of the extrados of the tube. The mandrel, with or without ball with spherical links, is mostly used to prevent wrinkles and ovalization. Standard tooling often must be modified in order to meet specific requirements of the products. CNC rotary draw benders can improve productivity, provide more consistent parts, in turn enabling our customer’s to save money and improve their bottom line.
