Problems solved by technology

[0002] In recent years, the number of newly built high-rise buildings has spread all over the world, and the increase in China is even more alarming. Moreover, the high-rise buildings are getting higher and higher, and the appearance is more and more distinctive. There are more and more demands for extruded materials for decorative curtain wall materials. Designing a mold with a large circumscribed circle and thin walls according to the ideal extrusion characteristics of the extruder often results in high extrusion pressure, stuffy car, and inability to squeeze. The extrusion production efficiency Low, if the extrusion pressure is particularly large and cannot be squeezed, it will cause failure to supply
For example, the circumscribed circle of the QR5405 section is 310.6mm, the wall thickness is 2.6mm, the theoretical weight is supplied, and the 3800T machine with an extrusion barrel of φ315mm has to widen the mold after opening the mold. The extrusion pressure is relatively high, the forming effect is poor, and the pass rate of the machine is low.
Now it is necessary to open a mold on a 2700T machine with a diameter of 258mm in the extrusion cylinder. The amount of expansion is particularly large, which can be said to be even more difficult. It is difficult to extrude qualified profiles with a wide expansion mold designed according to ordinary methods.

preparation example Construction

[0035] The preparation process of the above-mentioned hot extrusion aluminum profile mold is as follows: firstly, the first layer of the entrance of the upper mold 1 is made into a super-large wide-spreading curve taper 11 on both sides, which is similar to first converting a circular extrusion cylinder into a flat extrusion cylinder, which is equivalent to changing round ingot extrusion into flat ingot extrusion, increasing the supply of metal on both sides as much as possible; then the tongue core 12 located in the middle of the entrance side of the upper die 1 is designed as a flexible curved convex cone Platform structure, which distributes the metal flow, guides the metal flow to both sides through the flexible curved convex frustum structure, and the metal flow enters the lower die 2 through the diversion hole 17; the lower die 2 adopts a secondary welding chamber, through the first The welding chamber 21 and the second welding chamber 22, and a large mil is made at the b...

Embodiment 1

[0051] Please refer to Figure 1 to Figure 7 Shown, embodiment one of the present invention is:

[0052] A hot extruded aluminum profile die, comprising an upper die 1 and a lower die 2 connected to each other;

[0053] The entrance of the feed end of the upper die 1 is provided with a wide-spreading curved tapered surface 11; the middle part of the upper die 1 is provided with a tongue core 12, and the tongue core 12 is a frustum of cone structure with a circular arc protrusion at one end. , the arc protrusion of the tongue core 12 is located inside the upper die 1, and the other end of the tongue core 12 is located outside the discharge end of the upper die 1;

[0054] The opening of the tongue core 12 is provided with a first working belt 13, the right end of the first working belt 13 is provided with an upper empty knife 14, and the left end of the first working belt 13 is provided with a lower empty knife 15;

[0055] The discharge end of the upper mold 1 is provided wi...

Abstract

The invention relates to the technical field of die machining, in particular to a hot extrusion aluminum profile die. The hot extrusion aluminum profile die comprises an upper die and a lower die which are connected, a broadsiding curve taper face is arranged at the inlet end of the feeding end of the upper die, a tongue core is arranged at the middle portion of the upper die, one end of the tongue core is provided with a frustum structure with arc protrusions, the arc protrusions of the tongue core are located inside the upper die, the other end of the tongue core is located outside the discharging end of the upper die, first working tape is arranged at the position of an opening of the tongue core, an upper air knife is arranged at the right end of the first working tape, and a lower airknife is arranged at the left end of the first working tape. The hot extrusion aluminum profile die has the beneficial effects that the first layer of an inlet of the upper die is made to be in oversized broadsiding curve taper shapes on the two sides, the tongue core located on the middle portion of the inlet side of the upper die is designed to be of a flexible curve protrusion frustum structure, metal flow is reasonably distributed, the die overall structure is reasonable in design, the extrusion pressure is small, and the molding effect is good.
