II shrinks, and when fixed plate I is moved downwardly to origin-location, controls cylinder I and cylinder II stops shrinking,
The steel pipe being bent over is taken away by workman.Control cylinder III and cylinder IV shrinks, when portable plate I and portable plate II
When rotating back to origin-location, control cylinder III and cylinder IV stops shrinking.
Because also including angle scale, the angled dish of portable plate II installed in front.On angle scale indicated by pointer
Angle be exactly the angle that steel pipe is bent over, it is simple to workman uses this device.
Because baseboard material is rustless steel, the service life of this device can be extended.
Because pinch roller and cushion block material are 45 steel, pinch roller and cushion block can be made to be not susceptible to break or wear out, prolong
The service life of this device long.
(3) beneficial effect
This utility model has reached that volume is little, simple in construction, easy to operate, the adjustable effect of bending angle,
Significantly improve work efficiency.
