For achieving the above object, the utility model is by the following technical solutions:
A kind of lifting detent mechanism of apparatus for bending of long U bending machine, comprise bending support, bending base plate, Bending Mould and thread connection mechanism, the bending support is provided with the bearing-surface of supporting bending base plate, and thread connection mechanism is fixed on the bending base plate on the bending support;
The bending base plate has first station and second station on the bending support, have the difference in height of setting between first station and second station;
Be installed with at least two feather keys on the bearing-surface, each feather key outstanding part from bearing-surface all has a support plane and a guide ramp, all support planes are all contour, all guide ramp are parallel to each other, the intersection of support plane and guide ramp is perpendicular to the rotary centerline of Bending Mould, and the difference in height between support plane and the bearing-surface equals the difference in height between first station and second station;
The bending base plate is when first station, and the bottom surface of bending base plate contacts with the bearing-surface of bending support;
The bending base plate when second station, the support plane contact of the bottom surface of bending base plate and feather key;
The bottom surface of bending base plate is provided with at least two and dodges groove, dodge groove and when the bending base plate is in first station, hold the ledge of corresponding feather key, one sidewall of dodging groove is the inclined-plane, this sidewall is parallel with the guide ramp of feather key, when the bending base plate was changed between first station and second station, this sidewall contacted with guide ramp.
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 first station to second station.
More than each technical measures can select a use, use also capable of being combined.
The utility model is simple and reasonable, and the location accurately, and is easy to operate, easy to manufacture.Adopt long U bending machine of the present utility model 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 be earlier makes and two kinds of two bending passages that caliber is corresponding on mould, utilizes the utility model to the positioning of apparatus for bending again, determines two stations, and the station of switching apparatus for bending makes two bending passages aim at pipe fitting to be processed in turn.
