A T-shaped copper material extrusion die

Abstract

The invention discloses a T-shaped copper material extrusion die which comprises a forming die, a transition die, a shaping die and an extrusion punch, wherein the transition die is fixedly connected between the forming die and the shaping die, the forming die comprises a first die core, the shaping die comprises a second die core, a third die core and a fourth die core are respectively arranged at two ends of the transition die, the structure size of the first die core is greater than that of the second die core, the structure size of the third die core is identical with that of the first die core, the structure size of the fourth die core is identical with that of the second die core, the third die core and the fourth die core are in smooth transition, and the appearance structure size of the extrusion punch is identical with that of the second die core. Through the mode, the T-shaped copper material extrusion die is simple in structure, produced T-shaped steel is uniform in size, high in bearing capacity, difficult to bend and deform, good in deformation resistance performance, and stable in product performance.

Description

technical field [0001] The invention relates to the field of profile processing, in particular to a T-shaped copper material extrusion die. Background technique [0002] Metal profiles other than the commonly used profiles announced by national standards are collectively referred to as special profiles. Most of the T-shaped copper materials are drawn by drawing dies, and due to the structural design requirements of the tensile model core and cavity, most of the existing T-shaped steel materials are as figure 1 As shown, the flange 10 and the web 20 of the T-shaped steel are perpendicular to each other, and the connection between the flange 10 and the web 20 is at right angles or excessively rounded, and the deformation resistance of this T-shaped steel is obviously insufficient. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a T-shaped copper material extrusion die for making T-shaped steel materials with unif...
