Pressure, shapes base flange and muscle is indulged in part, and semi-finished product one are made;
Four, hydraulic cylinder control sectional female die keeps supplying position motionless, and hydraulic press top shoe pushes, and makes to be fixed on top shoe
On punch-pin mandrel drive the metal material on semi-finished product one to continue traveling downwardly, carry out axial-radial Splicing Mechanism, realize primary dress
Mould can shape thin-walled, wide flange and its external vertical muscle simultaneously, and semi-finished product two are made;
Five, heat treatment and outer surface machine add, and final cylindrical member is made.
Further, the sectional female die divides valve, the 4th point of valve to form by first point of valve, second point of valve, third;Each point
The whole L-shaped structure of valve;First point of valve, second point of valve, third divide valve, the 4th point of valve to be equipped with several arc notch;
Further, the punch-pin mandrel generally T-shaped structure.
After adopting the above scheme, the present invention has the beneficial effect that:The wide flange stud cylindrical member axial direction-of thin-walled of the present invention
Radial Splicing Mechanism shaping dies realizes primary die-filling thin-walled, flange and its outside of can shaping simultaneously and indulges muscle, shortens
Manufacturing process reduces labor intensity, has many advantages, such as that manufacturing process is short, the high and low cost of precision.
