2. Description of the Related Art Conventionally, for example, as shown in FIGS.
A so-called solid-type extruded aluminum member (20) consisting of an opening facing wall (20a), left and right side walls (20b) and (20c) and having an opening (21) extending in one direction in a length direction. ,
Molding with a die causes variations in dimensions and cross-sectional shapes, for example, before and after the entire extrusion length, for each extruded billet, or also for each extrusion date, and these dimensions and cross-sectional shapes are off-line deviated from the production line of the profile. Had to be corrected with a roll.

[0003] In other words, the dimensional error of the extruded aluminum material (20) immediately after extrusion molding is a minus case where the width of the opening (21) is narrower than a specified size, and a case where the width of the opening (21) is specified. There is a so-called plus case where the dimension is wider than the dimension.

In the case of the former minus, as shown in FIG. 3, the opening (21) of the extruded section (20) is arranged downward, and the opening facing wall (20a) (upper side) is placed. Is pressed from the inside of the extruded profile (20) by a pair of straightening vertical rollers (23) and (24), and the opening facing wall (20a) is pressed against the two rollers (23) and (24). ), It is necessary to correct the cross-sectional shape and dimensions of the aluminum extruded profile (20) by pressing from the outside of the extruded profile (20) with one vertical straightening roller (25) arranged in the middle and outside of was there.

On the other hand, in the case of the latter plus, as shown in FIG. 4, the opening (21) of the extruded profile (20) is arranged upside down, and the opening facing wall (20a ) (This is the lower side) is pressed from the outside of the extruded profile (20) by a pair of straightening vertical rollers (23) (24), and the opening facing wall (20a) is By one straightening vertical roller (25) arranged between and inside the two rollers (23) and (24),
It was necessary to correct the cross-sectional shape and dimensions of the aluminum extruded profile (20) by pressing from the inside of the extruded profile (20).

[0006]

However, according to such a conventional method, it is not necessary to adjust the roll set and the roll pitch in accordance with the error in the size and cross-sectional shape of the extruded aluminum member (20). It is extremely troublesome, and it is necessary to provide a process for straightening the extruded profile using rolls on the so-called off-line, which is off the production line of the extruded profile. There is a problem that the labor and labor for performing the material straightening process are required, and the production cost of the extruded aluminum material is high.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to directly correct the dimensions and cross-sectional shape of an aluminum extruded shape immediately after molding using a pair of rollers. Therefore, there is no need to provide a conventional roll straightening process for extruded aluminum profiles off-line from the production line, so that equipment costs are very low and the process for straightening extruded profiles is carried out. No labor and effort are required, and the manufacturing cost of the extruded aluminum material is low, and the tolerance of the cross-sectional dimension is JIS.
Within the range of 1/4 to 1/2 of the special grade specified in the standard,
An object of the present invention is to provide an apparatus capable of producing a high-quality aluminum extruded profile with extremely high dimensional accuracy.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a die extrusion direction for forming a solid type aluminum extruded profile having a longitudinally extending opening on one side. On the front side, a bolster having a space through which the aluminum extruded profile immediately after extrusion passes is arranged, and a pair of rollers for guiding both side edges of the opening of the aluminum extruded profile immediately after extrusion are disposed in the space of the bolster at a predetermined interval. The gist is an apparatus for manufacturing extruded aluminum members, which is arranged every other one.

[0009]

According to the above-described apparatus for manufacturing an extruded aluminum material, immediately after hot extrusion by a die, both side edges of the opening of the extruded aluminum material are guided by a pair of correction rollers in the bolster space. The inner dimension between the side edges of the opening is corrected to a width equal to the arrangement interval between the outer sides of the two correcting rollers, and at the same time, the cross-sectional shape is corrected.
Moreover, the tolerance of the cross-sectional dimension is, for example, JIS H410
It is possible to manufacture a high-quality aluminum extruded shape with extremely high dimensional accuracy, which is within the range of 1/4 to 1/2 of the special grade defined by 0 (aluminum and aluminum alloy extruded shape).
