Further, described projection is column structure, and groove is the cross section coordinated with projection is the structure of semicircle.The periphery of column structure is level and smooth curved surface, just having less resistance, being convenient to insertion and the dismounting of limiting plate when inserting limiting plate and groove fit, improves the convenience of limiting plate operation.
Further, clamp structure is provided with contiguous block, expansion link by the U-shaped plate of its end and contiguous block hinged.U-shaped plate structure is simple to operation, is also convenient to dismounting.
Further, fixed mount is provided with some stiffeners.During Driven by Hydraulic Cylinder, power is comparatively large, stiffener the stability that can increase fixed mount is set.
To sum up, the invention has the beneficial effects as follows:
1, the projection of the present invention by being provided with on two columns coordinated with cylinder I for placing limiting plate, the length of the bend pipe short end straight tube after bending according to actual needs, the projection coordinated with limiting plate is determined by rule, and then to be established by the card between the groove of limiting plate and projection limiting plate is fixed on projection, before iron pipe bends, iron pipe is inserted the annular groove between parting bead on cylinder I periphery, the end of iron pipe is contacted with limiting plate, so, bend pipe after bending not only uniform specification, and the length of the short end straight tube of bend pipe can be regulated.
2, the present invention adopts machinery to bend iron pipe, has not only saved human resources, has improve efficiency.
3, the present invention can bend multiple bend pipe simultaneously, not only increases operating efficiency, and guarantees the uniform specification of the bend pipe bent.
