Outline
|
Kurimoto's proven high-precision end bending features bring precise circularity to desired application. KURIMOTO's Bending Roll is Top Roll Horizontal Movement type. Value added features of KURIMOTO's Bending Roll, such as Top Roll crowning and adjustable Back-Up Rolls enable to achieve precise circularity and cylindricality to application with wide range of material thickness. |
Features
NC Control Amount of Top Roll Ram Down is automatically calculated by inputting application data, which reduces workers operation. High-Precision End Bending Being formed in the procedure that Top Roll moves Front/Rear direction, the ends of the material plate are firmly bended as well as the one done by ordinal press. Precise Circularity and Cylindricality Top Roll Crowning and adjustment of Back-Up Roll help correcting deflection of both Top Roll and Back-Up Rolls to be more precise circularity and cylindricality of applications, which reduces time of post procedure. High Rigid Mechanical Structure Frame is rigidly designed based on pressure capacity and width of application materials. Top Roll Ram- Down mechanism and rigid & compact lower frame simplify foundation construction. Energy Saving and Eco-Friendly While the unit is not loaded, inverter control minimizes pump unit motor output and reduces Electricity Consumption of pump unit motor. |

| Proven NC Control system ensure precise bending result which used to heavily rely on worker's experience and know-how, by inputting details of application. |
Every workers can operate KURIMOTO Bending Roll easily by inputting material, |
NC Control
Semi Automated type(TNC) is recommended for Various kind but low-volume production
Fully automated type(CNC) is recommended for Various kind with high-volume production
Top Roll travel and Ram-Down are automatically calculated by inputting details of application so unexperienced application can be processed easily in a short time.

Portable machine
Main cylinders for Top Roll are designed as to press down application, and reduce lower frame height so material loading height remains low.
Frame is rigidly designed so anchor bolts are not required to install machine.

Performance
 |
 |
For End bending, clamp distance is freely configured at pressure point, then Top Roll to press, so High-precision End Bending, identical result to the one done by ordinary press, is expected.
KURIMOTO Bending Roll only press the end of the material, not feed the material and press, then rewind the material thus the fear of Rolling the material is eliminated.

Post-rolling welding and assembly processes are significantly shortened.
Bending Method
Are you really satisfied with your 4-roll bending machine?
Conventional 4-Roll Bending Process
The Problem:
- Straight sections always remain at the leading and trailing edges of the rolled sheet.
- While an experienced machine operator can partially correct these straight sections, no machine yet has been able to eliminate them completely.
Kurimoto's New 3-Roll Bending System
The Kurimoto's sytem uses a top roll that changes position during the bending operation to produce leading and trailing edges formed to almost 100% perfect curves. The result? A rolled form with almost perfect concentricity - right down to the edges. How is it done? A computerized control system continually sets both the height and horizontal position of the top roll during the bending process. It's all automatic, so anyone can operate the machine.
Concentricity check after bending shows almost 100% accuracy in the cross section of the curve.
