Machine equipment-/basic accessories:    

– Compact, exposed bending head
– With automatic operation sequence via incorporating switch key to provide a choice of operation
– Starting of the machine via pushbutton
– Manual by hand button
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)
– Semi automatic, starting with mandrel in forward position
Pressing causes clamp and pressure die to come on and start bending sequence on reaching desired angle, mandrel goes back, clamps open, bending head returns and mandrel comes forward to start position
– Following pressure die with linear bearing
– 500 mm following and a constant support of 200 mm
– Forward movement via pressure control valve
– Returned by hydraulic cylinder
– Wide opening of pressure die to allow off set bend device to move to a short distance from bending head
– Bending direction clockwise
– With hollow shaft for using tooling for small radii
– For radii starting from 1,5 x D tube diameter
– Manual tool resetting
– Automatic bending tool engagement
– All functions are fully hydraulic
– Machine stationary
– Colour RAL 3020 red, 7047 grey
