Title:
TUBE MATERIAL MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/017996
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a molding device that a plurality of split dies can be equally
clamped with a single drive source. [MEANS FOR SOLVING PROBLEMS] In subjecting
a tube material to drawing and caulking, a tube material is first externally inserted
into a cored bar (30). In this case, upper and lower split dies (11, 12) constituting
an external die (1) are in a mold opened state. From this state, an upper split die
(11) constituting an external die (1) is moved downwardly. This allows four split
dies (21, 22, 23, 24) constituting an inner die (2) to evenly move toward the center,
and an exhaust pipe is subjected to drawing and caulking simultaneously by molding
faces (26, 27) formed on the inner face of the four split dies.
