The pipe shrinking machine is a hydraulic automatic pipe end forming machine controlled by the integrated control touch display screen to expand and shrink the end surface of the pipe under normal conditions. The replacement of the mold can expand, shrink, bulge, and upset the pipe. Pipe ends such as ribs are processed and formed.
Tube necking is a forming process that reduces the diameter of the end of the tube blank. The tube blank enters the deformation zone under the action of axial force, produces tangential shrinkage shrinkage plastic deformation in the deformation zone, and then enters the stable zone, and finally forms a reduced end diameter.
Tube flaring is a forming process to expand the diameter of the end of the tube blank. The flaring shape can be tapered or cylindrical. The tube blank enters the deformation zone under the action of axial force, and produces tangential stretching in the deformation zone. The flaring is plastically deformed, then enters the stable deformation zone, and finally takes shape.
The pipe end forming machine is widely used in the processing and forming of pipe fittings, automobile oil pipes, air pipes, water pipes, air conditioning pipes and other connecting parts. It is an ideal pipe end forming processing equipment. The processing shapes include: convex, concave, long flat, square , Oblique, V-shaped, open elbow, flat elbow, etc. are manufactured into forming molds according to productization.
