One of the machine functions, tube necking is a molding process that reduces the diameter of the tube end. The tube blank acts as an axial force into the deformation zone, produces a tangentially shrinking plastic deformation in the deformation zone, then enters the stable zone, and finally forms a reduced end diameter.
And the flaring of the pipe is another forming process that enlarges the diameter of the end of the pipe blank. The flaring shape can be conical and cylindrical. The pipe blank enters the deformation zone under the action of axial force and generates tangential stretching in the deformation zone. Flaring plastic deformation, and then enter the stable deformation zone, and finally forming.
-- Mechanical features
It is equipped with emergency stop device. Both manual and automatic operations are available. Shrinking stroke 100mm. The max. workpiece length is 450mm, with no minimum workpiece length. Forming shapes can be convex, concave, sectional, long 7 flat, square, V-shaped, open elbow and flat elbow. The machine is with the syraight guide roller as the carrier, can run without abrasion, and the products have a good repeatability, which are fit for the treatment of the pipe end in the iron pipes, furniture, automobile air conditioners and fuel oil pipes.
The machine is with hydraulic synchronic system, make sure the processing accuracy. Microcomputer control, hydraulic pressure actuation, it works steadily.
