Abstract
The invention provides a hard flat aluminum wire extrusion forming mold which can solve the problem that the tensile strength of a flat aluminum wire processed by a conventional extrusion forming mold cannot meet requirements. The extrusion forming mold includes an external mold sleeve and an internal mold core, the internal mold core is mounted in the external mold sleeve, and the bottom face of the internal mold core is a plane; the extrusion forming mold is characterized in that the inner side face of the bottom of the external mold sleeve is a plane, the inner side face of the bottom of the external mold sleeve and the bottom face of the internal mold core form a narrow rectangular extrusion mold cavity.
Description
Technical field
The present invention relates to the processing tool field of plain conductor, especially relate to the processing tool of duralumin lenticular wire, be specially the mold for extruding and forming of duralumin lenticular wire.
Background technology
The extrusion molding of metallic conductor is that metal wire embryo is put into extrusion die chamber, under the effect of high temperature and pressure, extrudes from extrusion die, thus obtains the metallic conductor of certain size and cross sectional shape.Existing flat aluminium wire extrusion die is shown in Fig. 1, it comprises outer die casing 2 and inner mould core 7, inner mould core 7 is installed on the bottom of outer die casing 2, the flat bottom surface 6 of inner mould core forms tapered squeezing die cavity 5-1 with the bottom conical surface 4 of outer die casing, and its tensile strength of flat aluminium wire adopting the extrusion process of existing flat aluminium wire extrusion die to obtain is about 75N/mm
2, the tensile strength that cannot meet current duralumin lenticular wire reaches 90N/mm
2above instructions for use.
Summary of the invention
For the problems referred to above, the invention provides the mold for extruding and forming of duralumin lenticular wire, it can solve and adopt the flat aluminium wire tensile strength of existing mold for extruding and forming processing to meet the requirements of problem.
The mold for extruding and forming of duralumin lenticular wire, it comprises outer die casing and inner mould core, described inner mould core is installed in described outer die casing, the bottom surface of described inner mould core is plane, it is characterized in that: the bottom inside face of described outer die casing is plane, the bottom inside face of described outer die casing and the bottom surface of described inner mould core form narrow rectangle extrusion die cavity.
Further, described inner mould core comprises the first core rod, the second die sleeve, the 3rd die sleeve and the 4th die sleeve, the end face of described first core rod is flush-mounted in the bottom groove of described second die sleeve, the top stage face of described second die sleeve is flush-mounted in the bottom groove of described 3rd die sleeve, described 4th die sleeve is installed on described 3rd die sleeve, and the bottom surface of described first core rod is plane.
Beneficial effect of the present invention is: because the bottom inside face of outer die casing is set to plane by it, and the bottom surface of inner mould core is also plane, thus the bottom surface of the bottom inside face of outer die casing and inner mould core defines a narrow rectangle extrusion die cavity, this rectangle extrusion die cavity is little compared with the extrusion die cavity of existing flat type aluminium wire extrusion die, thus effectively can reduce the temperature in extrusion die cavity, thus make that the flat aluminium wire of each extrusion molding becomes harder, tensile strength also just improves greatly.
