Machine equipment-/basic accessories:  

– Bending direction clockwise
– With hollow shaft for using tooling for small radii
– Include wide opening pressure die, to allow the off set bend device with the long neck clamping to move directly behind the bending tool
– Following pressure die with linear slide bearing
– Positioning of the following pressure die depend on the radii
– Returned by hydraulic cylinder
– Two mandrel lifter
– Attention: For each tube-Ø you need a separate collet
– For a correct positioning of the mandrel the machine is equipped with a mandrel support
– the machine is conform to the electric and mechanical security guidelines and  the CE norm
– The emergency area in front of the machine is controlled via scanner
– Starting of operation via hand button
– Manual operation
Each function clamping on/off, mandrel forward/back, bending on/off initiated by selection and pressing of respective button (for proto type and sample production)
– With automatic operation sequence
– Injection by hand button or automatic in the bending operation clamping
– Incorporating switch key to provide a choice of operation
– Standard-norm-hydraulic components
– Incl. stairs and balustrade at the beginning and the end of the machine for an easy walk through the machine ground frame during tool changing
– Machine stationary
– Colour RAL 3020 red, 7047 grey

Control description:  

– Fitted with 3-axis control of the bending angle, the rotation axis and the longitudinal movement in the different planes
– The bending axis, the rotation axis and the length axis are coupled with each other, it ensues a permanent actual and nominal comparison also the control checks the tolerance and actuates further operations
– Integrated computer – IBM-compatible, current technology
– It ensues a permanent actual and nominal comparisation on the screen
– User surface Windows
– Input of all dates can be directly or online with a IBM compatible PC
–  Separate control element including Tozchpanel for setup and start of automatic cycle

 

Standard equipment CNC control:    

– With max. 20 different positions of each tube, all positions are controlled in the PC program
– Possibility to store 1 Mio. tubes with 20 positions each under drg. numbers
– After input you can store the tube
– Storage of the drg. numbers according to WIN Standard
– The off set bend device moves to the front position for an easy input and output of the tubes
