Case of Innovative solutions

【By conventional way of bending】

・A work piece of small diameter (mainly φ5～φ6) and long size (of longer than
　　1500 ～2000mm)is normally machined by cross-type N/C pipe bender or specialty
　　machine.（Note:cross bender = axial motion is made orthogonal to the tooling post.） 
 

【Production problem prevailing at moment】

　・In bending a long-sized work piece, the piece tends to swing out larger especially
　　when the rear half of the material is at speedy rotation, easily causing poor bent
　　shape at the end. Alternatively the bending speed must be turned slower at the sector
　　where larger swinging is seen likely, leading to longer machining time at the end.

　・An operator-assist holding of the work piece may be one solution against this problem,
　　but again the machining time goes longer with higher possibility yet existing for
　　instable quality production.

・Manufacturing by specialty machine is followed by different problem as the machine
　modification will take rather longer time to meet design change of the product.

・Also the specialty machine has no versatility to meet different machining designs
　or work pieces specifications.

【Bending by the robotic bender】

    ①Advantages are claimed against standard bending machines for 60%-faster bending
　　　motion and no requirement of unloading device.

　　②Thanks to remarkable decrease of poor quality bending caused by twisting and
　　　deflection of work piece during bending process, stable bending operation can be
　　　made by at speed- and accuracy-oriented operation with resulted advantage for
　　　higher per-day output.

　　③A work piece with pre-mounted fittings such as protective tube, rubber hose and/or
　　　stay can also be accepted as the bending robot executes bending motion of DBB and
　　　POB with itself keeping off these fittings

　　④Versatility of the machine can meet varieties of work specifications and higher
　　　rationalization of production has been achieved.

　　⑤Three-sized R bending   More work specification can be met without time-consuming
　　　tooling changes.

　　⑥Simulation Software（Optional） can be a powerful engine for prototype work in
　　　time- and material-saving.
