The invention relates to an iron pipe bending machine with adjustable curvature. The iron pipe bending machine with the adjustable curvature comprises a substrate, a fixed mount is arranged at one side of the substrate, fixed plates are arranged at two sides of the top of the substrate, a cross bar is arranged at the top of the substrate, a column I provided with a plurality of annular division bars on the outer circumferential surface is arranged between the fixed plates, connecting rods are arranged at two sides of the top of the substrate, a clamp structure is hinged to the ends of the connecting rods, clamp plates are arranged at two sides of the clamp structure and hinged to the fixed plates, a column II matched with the column I is arranged between the clamp plates, a hydraulic cylinder is arranged on the fixed mount, the clamp structure is provided with a Y type connecting block, one connecting end of the Y type connecting block is hinged to a hydraulic cylinder, the other connecting end is hinged to a screw rod, the screw rod is through arranged in a fixed plate fixed on the cross bar, and a plurality of limit blocks are arranged at the end of the screw rod. The iron pipe bending machine with the adjustable curvature adjusts the curvature of an elbow through increasing the limit block number, and therefore, the iron pipe bending machine with the adjustable curvature overcomes the problem that the existing mechanical bending cannot adjust the curvature of the elbow.

The invention discloses a die good in safety performance and convenient to adjust. The die comprises an upper die and a lower die, the upper die is installed on the upper portion of the lower die, and the lower die is rotatably installed on the upper portion of a base plate; a rotating shaft is vertically and rotationally installed at the top of the base plate, a driven gear is fixedly installed outside the rotating shaft, a support is installed on one side of the top of the base plate, a driving gear is rotationally installed on one side of the support, and the driving gear is meshed with the driven gear; after four supporting rods extend out, four rolling wheels make contact with the ground at the same time, and the rolling wheels can play a role in supporting the whole die at the bottom; the rolling wheels can facilitate the movement of the whole die at the bottom, and the die can be quickly moved to a required position only by pushing the die; and during parking, adjusting rods are screwed to drive the supporting rods to move upwards until the rolling wheels at the bottom enter storage grooves, the bottom of the base plate makes direct contact with the ground, and the whole die can be stably positioned.

The invention belongs to the technical field of reinforcement cage seam welding equipment and particularly relates to an automatic welding device of a reinforcement cage seam welder.
