Technique scheme can also be further improved by following technical measures:
Be fixed with gib block on the bearing-surface of bending support, the bottom surface of bending base plate offers gathering sill, and gib block embeds gathering sill and along the rotary centerline direction slippage of Bending Mould.
Guide ramp raises gradually along the direction of the first station to the second station.
Above each technical measures can be selected a use, also use capable of being combined.
The present invention is simple and reasonable, and registration is easy to operate, and is easy to manufacture.Adopt long U bending machine of the present invention on the basis that does not change mould the tubing of two kinds of different tube diameters to be processed, the range of work is wide.The user can make and two kinds of two bending passages that caliber is corresponding at mould first, and recycling the present invention positions apparatus for bending, determines two stations, switches the station of apparatus for bending, makes two bending passages aim in turn pipe fitting to be processed.
