CLEVER

CLEVER is the new CNC multistack, multiradius tube bending machine. It is completely electric, designed by Crippa for steel tubes up to 25mm in diameter. The Clever concept offers the market a tube bending machine based on the patented concept of side tilting of the head. This machine has a single head that can bend in two directions. It can also incorporate loading and unloading into the process cycle thus reducing production time.

The head therefore works independently loading, processing and unloading tubes which may even be complex, with extreme simplification of the bending process. In fact, this tube bending machine can load the new bar to be processed, while the head moves vertically and rotates to unload the finished piece. 

The left and right bending is done on the same bending former which has dedicated surfaces. The bending direction is reconfigured automatically and controlled by the 9 CN axes of the machine which simplify the positioning and release operations at the same time optimising the paths between the left and right bending stacks. The head moves only in the vertical direction and rotates around its rotation axis to position the tube in the groove. There is also a pneumatic balancing device that reduces power consumption during vertical movement and a system for rapid retraction of the tie rod. 

Programming is done using simplified UII interface software.  This tube bending machine can be configured with numerous optional accessories and can be connected to the Crippa I4.0 production control and performance systems.
