The invention discloses a pipe fitting bending device, which comprises an actuating unit, a workbench, a bending die, a first mandril, a second mandril, a clamp die, a pressing die, a profiling clamp die and a profiling pressing die, wherein the actuating unit is in drive connection with the bending die; the bending die is positioned on one side of the workbench; the profiling clamp die and the profiling pressing die are positioned on the upper layer of the workbench; the clamp die and the pressing die are positioned on the lower layer of the workbench; the bending die is positioned on the outer side of a pipe fitting to be bent; one side of the bending die is provided with a crease-resistant die which is positioned on the outer side of the pipe fitting to be bent; the first mandril is inserted into one end, which is positioned on the same side as the crease-resistant die, of the pipe fitting to be bent, and the second mandril is inserted into the other end; the clamp die and the pressing die are tightly attached to one side, in which the first mandril is inserted, of the pipe fitting to be bent; the profiling clamp die and the profiling pressing die are tightly attached to one side, in which the second mandril is inserted, of the pipe fitting to be bent. The pipe fitting bending device bends the pipe fitting, and is simple in structure; inner and outer sides of the bent pipe fittings are flat and smooth.
Description
technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a pipe fitting bending device. Background technique [0002] The bending and forming process of pipe fittings is widely used in manufacturing industries such as automobiles, ships, aircrafts, food machinery, and chemical equipment. For example, automobile turbocharger pipes are formed by bending steel pipes. In the processing practice, the automobile turbocharger pipe has two corners and the straight line between the two corners is very short. When the steel pipe is bent with a small radius, it is very easy to cause serious deformation of the bending shape, resulting in a significant crack on the inner side of the steel pipe. Wrinkled, the outer side is obviously compressed along the bending center, and its cross-sectional shape changes from the center of the circle before bending to a flat shape after bending, and the cross-sectional area also shrinks significant...
