The invention relates to a
metal elbow cold
extrusion molding device for
processing metal pipe fittings. The invention solves the defects of serious loss of filters, long
process time and high bending cost of
pipe fittings in the traditional
pipe bending technology which needs filling. The
metal elbow cold
extrusion molding device comprises an
extrusion mold core which can be inserted into a mold cavity and a core pushing stick for pushing the pipe fittings to be processed. The extrusion mold core comprises a basic shaft and a working end. The basic shaft is adapted to the inner
diameter of the mold cavity, at least one gap equal with the wall thickness of the
pipe fitting is arranged between the working end and the inner wall of the mold cavity, the projection of the working end along with the axial direction of the basic shaft is of a round shape, and the round shape is consistent with the inner
diameter of the
pipe fitting to be processed. The
axial projection of the working end is of the round shape, then the
pipe fitting can be repaired when the working end exits, the end part of the pipe fitting is of the round shape, the pipe fitting is formed by extruded and bended one-step molding and does not need cooling, the bending time is short, the operation is simple, the efficiency is high, the shape of the end part of the final pipe fitting is more in line with requirements, and the precision is higher.
