In booth #B7513 at FABTECH 2022, BLM GROUP is demonstrating its E-TURN all-electric tube bender in conjunction with an AL5 automatic tube loader. The system will be shown bending a seat frame part, highlighting E-TURN’s LH and RH bending capability.
Demo Specifications: The part will be bent with 25.4mm OD x1.65mm wt. 304SS bent using draw bending and variable radius (VR) bending technologies. The E-TURN will be configured with 63.5mm Centerline Radius (CLR) draw bending tools and Variable Radius (VR) tooling on both the left and right heads of the machine.
The AL5 loader will accept a bundle of raw material that it will separate out for loading into the E-TURN 40. The articulated head of the E-TURN 40 will utilize the bend tooling to clamp the tube and bring it to the collet for bending. The tube will be bent utilizing both the LH and RH draw and VR bending tools. After bending the tube will be automatically off loaded utilizing the bending head.
About the E-TURN: The E-TURN’s all-electric drive ensures precision control of the 15-axes movements, providing consistency, high accuracy, perfect quality bends and zero scrap. Tubes in most materials and section types—such as round, square, rectangle, flat sided, oval and elliptical—can be automatically loaded, bent and unloaded. The flexibility, accuracy and speed of the E-TURN makes it well suited for furniture, automotive, job shop, motorcycle and hydraulic pipe construction applications.
A key differentiator of the E-TURN is the VGP3D programming and 3D simulation software. By simply inputting the component bend coordinates, the complete bending program is graphically simulated, highlighting potential collision risks and producing the optimal working cycle. Component feasibility is checked virtually, eliminating the need for prototype tooling or physical testing on the machine. Unloading of the finished component is also automatically managed by VGP3D, with the 180-degree head rotation allowing the component to be unloaded in the position required.
Changeover times are significantly reduced and machine-setup simplified as all the critical settings for the machine tooling are managed automatically by the CNC, including clamps, pressure die, mandrel position, retraction, center line radius, etc. Additionally, the self-calibration feature enables true simultaneous axis movement with automatic adjustment of these settings.
The all-electric technology of the E-TURN offers reduced power consumption, typically offering 80% savings as compared to conventional hydraulic bending machines. Maintenance is also reduced due to simplified cabling and components.
The E-TURN is available in four sizes capable of handling maximum tube O.D. capacity ranging from 30mm x 2mm (1.18-in. x 0.079-in.) up to 50.8mm x 1.5mm (2-in. x 0.059-in.). Depending on the system, the E-TURN offers a minimum bending radius of 25 – 35mm and a maximum bending radius of 150 to 165mm.
