Further, described base upper surface guide rail is groove.
Again, described pedestal comprises two pairs of montants and a pair cross bar is connected to form inverted U-shaped, described guide hole is arranged on montant and cross bar, and the outboard end of guide pillar connects a plate, and these connecting plate central authorities establish the center screw coordinated with left and right side leading screw and upper spindle.
Compared to existing technology, the utility model tool has the following advantages:
1. the utility model is by carrying out orthopedic to the port after U-shaped cutting parts, eliminate distortion that port produces because of shear action and the resilience that residual stress release occurs, be more suitable for the port after cutting parts than " crossing curved and back bending " and " with interior roller back-flexing " method orthopedic;
2. to be applicable to the port of open-ended formula part orthopedic for the utility model, and the part port being not only applicable to rolling formation is orthopedic, is also applicable to port that is stamping, laser-welded product orthopedic;
3. apparatus structure advantages of simple provided by the utility model, low cost of manufacture, technique effect is obvious, and obvious economic, can be trimmed to qualified products by port below proof part.
4. the utility model apparatus for correcting can correct the local shape of part end quickly and easily, is conducive to improving U-shaped connecting elements dimensional accuracy, reduction in the numbers of seconds and manufacturing cost.
