Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Such as Figure 1-3 As shown, the present invention provides a profile porous self-bending extrusion die, which is especially suitable for a kind of L-shaped aluminum profile (such as Figure 7 Shown) extruded self-bending. Specifically, the profile porous self-bending extrusion die of the present invention includes a die body 1, and at least one diversion cavity is provided on one side of the die body 1, such as figure 1 In the shown embodiment, the mold body 1 is provided with four guide cavities, namely the first guide cavity 2 , the second guide cavity 3 , the third guide cavity 4 and the fourth guide cavity 5 .

[0038] It can be understood that the number of guide chambers can be selected according to actual needs, which is not limited in the present invention. In order to illustrate the gist of the present invention, the present invention will be described ...

Abstract

The invention relates to a profile porous self-bending extrusion die, and belongs to the technical field of dies. The technical problem that the cross section is prone to deforming due to large stressborn by the outer side surface of a profile existing in the prior art is solved. According to the profile porous self-bending extrusion die, because the two ends of a first semicircular cavity wall are connected to the first end of a first straight cavity wall and the first end of a first curved surface cavity wall correspondingly, the metal flow can be adjusted so as to enable metal to flow intoa material inlet opening more steadily and enable the metal to flow unevenly, so that a bent part is directly extruded, the profile is not subject to transverse moment force, and the outer side of the profile is reduced or the cross-sectional deformation is prevented.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a profile porous self-bending extrusion mold. Background technique [0002] Bending pipe profiles are widely used in machinery, automobile, aviation and other manufacturing fields. The forming process of traditional curved profiles is usually extrusion first and then bending. This type of processing method has a simple mold and a relatively mature process, but bending processing can easily lead to profile forming defects, such as bottom wrinkling, poor mold bonding, and forming accuracy in the stretch bending process. Low-level defects, the bending curvature of the bending process is uneven, the forming accuracy is low, the springback radius of the roll bending process is large, multiple forming and repeated corrections are required, and problems such as inner layer wrinkling and sinking are prone to occur. [0003] Extrusion and bending integrated molding is used in the prior art...
