Description

TECHNICAL FIELD

[0001] The utility model relates to a tooling, especially an extrusion outlet heat preservation tooling. BACKGROUND

[0002] With the development of traditional automobile light weight and the demand of new energy automobile to structure weight reduction, the steel is replaced by aluminum has become the development trend of automobile industry. The 6XXX series aluminum alloy which can be treated by aging strengthening has excellent formability, good surface quality and high strength, and is the ideal aluminum alloy material for automobile covering part. Solid solution treatment can significantly change the microstructure of the alloy, thereby affecting the strength of the alloy, so the solid solution effect of the material will directly affect the final mechanical properties.

[0003] Hot extrusion is a common aluminum alloy processing method, during extrusion, the aluminum bar is deformed into aluminum alloy profile with fixed section through the die, usually, there is a distance of about 2 meters between the extrusion die and the middle of the water tank, the extruded aluminum alloy will have a temperature drop process of 5-20 DEG C during the distance, and the mechanical properties of part of the material will decrease significantly during the temperature drop process. SUMMARY

[0004] The utility model discloses a kind of extrusion outlet heat preservation toolings, reduce the adverse effects of temperature drop on material.

[0005] To achieve the above object, the utility model adopts the following technical scheme: a kind of extrusion outlet heat preservation tooling, characterized by, including fixed ring, the fixed ring upper portion is provided with sealing plate, the fixed ring one side is provided with arc wall, the arc wall one side is provided with cover plate, the arc wall and cover plate form heat preservation cavity, the arc wall one side is provided with aperture, the aperture is provided with limit pin.

[0006] Further: the sealing plate is arranged in the inner side of the upper portion of fixed ring.

[0007] Further: the cover plate one end extends to the inside of fixed ring.

[0008] Compared with prior art, the utility model has the beneficial effects that: heat preservation tooling is additionally arranged in the distance between die outlet and water tank inlet, to reduce the adverse effects of temperature drop on material. BRIEF DESCRIPTION OF DRAWINGS

[0014] Example 1

[0015] Reference signs: 1 fixed ring, 11 sealing plate, 21 arc wall, 21a gap, 21b limiting pin, 22 cover plate. Figs. 1 to 4 A extrusion outlet heat preservation tool, comprising a fixed ring 1, a sealing plate 11 arranged on the upper part of the fixed ring 1, an arc wall 21 arranged on one side of the fixed ring 1, a cover plate 22 arranged on one side of the arc wall 21, the arc wall 21 and the cover plate 22 forming a heat preservation cavity, a gap 21a arranged on one side of the arc wall 21, and a limiting pin 21b arranged at the gap 21a.

[0016] In the example, the sealing plate 11 is arranged on the inner side of the upper part of the fixed ring 1 (close to the side of the arc wall). One end of the cover plate 22 extends into the fixed ring.

[0017] The heat preservation tool is installed between the extruder die and the water tank, and a limiting groove (generally U-shaped in cross section) is arranged at the extrusion outlet of the extruder (the limiting groove can be fixedly connected with the extruder, and the limiting groove is an example of the limiting groove). During installation, the limiting pin of the heat preservation tool is pushed into the limiting groove for limiting, and then the fixed ring is fixed on the extruder. The heat preservation tool is additionally arranged in the path from the die outlet (the outlet of the extruder die) to the inlet of the water tank, so as to reduce the adverse effects caused by cooling.

[0018] Example 2

[0019] The difference between this example and example 1 is that, in order to facilitate installation and use, the cover plate of the extrusion outlet heat preservation tool is provided with a threaded hole (not shown in the figure) close to the fixed ring.

[0020] The above only describes preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions that belong to the principle of the present application are within the protection scope of the present application. For those skilled in the art, some improvements made without departing from the principle of the present application are also considered to be within the protection scope of the present application.
