Next, an embodiment of the present invention will be described with reference to the drawings.
The patterning method for the aluminum profile according to the present invention will be described with reference to the process diagrams of FIGS.
In the figure, the extrusion process I, the cooling process II, the tension correction process III, the cutting process IV, the heat treatment process VI, and the alumite treatment VII are not particularly different from the conventional extrusion process of an aluminum profile. What is important in the present invention is that a patterning step V by pressing is included between the cutting step IV and the heat treatment step VI.

In the extrusion process I, a billet made of aluminum or an aluminum alloy is extruded using a known extruder 1. By this step, the billet becomes the aluminum profile A.
In the cooling step II, the aluminum profile A is cooled on the cooling bed 2 by air cooling or furnace cooling.

In the tension straightening process III, both ends of the aluminum profile A are held by the grab of the stretcher 3 and pulled in the longitudinal direction. This corrects bending and the like.
In the cutting step IV, the aluminum profile A is cut to a desired length with a cutter.

  In the patterning step V, a three-dimensional pattern such as bamboo knots or wood grain is patterned on the aluminum shape A by pressing. By this step, an aluminum profile A that looks like bamboo or wood is obtained. This step will be described in detail later.

The heat treatment process VI refers to a process of performing artificial age hardening after cooling (cooling process II) from high temperature processing (extrusion process I). For this heat treatment, a known heat treatment furnace 5 or the like is used.
The alumite treatment step VII is a step of immersing the aluminum shape material A in the chromic acid solution. By this step, the surface of the shape material is removed and degreased, and a rust prevention treatment can be performed.

  In the present invention, the patterning step V is characterized in that it is first performed before the heat treatment step VI and secondly processed by a press such as a press press or a roll press.

In the present invention, as described above, the patterning step V is performed before the heat treatment step VI. The first feature is as follows.
The tensile strength of the aluminum profile A changes as follows according to the progress of the machining process.
a) Immediately after the extrusion step I, it corresponds to the one that has been re-baked to obtain the softest state. For example, in the case of an aluminum shape of alloy number 6063, the tensile strength is 90 N / mm ² and the proof stress is 50 N / mm ^2. It is.
b) From the cooling step II to the cutting step IV, it corresponds to a material which has been naturally aged after being cooled from high temperature processing. If the aluminum shape A is alloy number 6063, the tensile strength is 150 N / mm ² and the proof stress is 90 N / a mm ^2.
c) Finished heat treatment step VI corresponds to a product which has been subjected to artificial age hardening after cooling from high-temperature processing. In the case of aluminum shape A of alloy number 6063, tensile strength 185 N / mm ² , yield strength 145 N / mm ² and composed.

  As described above, the tensile strength and the proof stress are increased in the order of a) → b) → c). Therefore, the patterning process V is performed while the aluminum shape A before the heat treatment of c) is still soft. It is the feature.

Next, each embodiment of the patterning process will be described.
The processing of the bamboo-like aluminum profile A shown below uses a press press. The processing of the woodgrain aluminum profile B, the woodgrain aluminum profile C and the geometric pattern aluminum profile D uses a roll press.

(Bamboo tone aluminum profile A)
First, a patterning method for the bamboo-like aluminum profile A will be described.
The pressing press 10 in FIG. 3 is a press for processing the aluminum profile A into bamboo. In the press 10, the ram moves up and down above the bed, a lower mold is placed on the bed, a pressing mold (upper mold) is attached to the lower end of the ram, and the pressing mold can be pressed against the material manually or by power. Any type of press may be used.

FIG. 5 shows a bamboo-like aluminum profile A patterned by the press 10, and the surface shown in FIG. 5 (A) is an aluminum profile A after processing with a k-shaped protrusion k representing a bamboo knot. The rear surface shown in FIG. (B) is an unprocessed aluminum profile A that does not have node-like projections.
(C) As shown in the drawing, the cross-sectional shape of the aluminum profile A is composed of a curved main body a1 and L-shaped ribs a2 rising from both sides and extending outward. The width W of the main body a1 is, for example, 100 mm, and the radius of curvature R is, for example, 500 mm. However, the dimensions are not limited to these dimensions.

  Returning to FIG. 3, reference numeral 11 denotes a lower mold, and the cross-sectional shape is a wide groove shape in which the central portion 11a is recessed and both end portions 11b rise. The central portion 11a is curved so as to be recessed downward with the same curvature radius as that of the main body portion A1 of the aluminum profile A. The lower mold 11 is made of an elastic synthetic resin that is difficult to be damaged by impact, for example, the trade name MC nylon.

Reference numeral 12 denotes an upper die, which is a block-like member made of a light metal such as aluminum. A groove 12a that opens downward is formed in the central portion in a side view. The front and back lower surfaces of the groove 12a are portions to be the pressing portion 12b. The lower surface of the pressing portion 12b is curved in the width direction, and the radius of curvature R is the same radius as the central portion 11a of the lower mold 11.
A tooth mold 12c is fitted into the groove 12a and is fixed with a bolt or the like. Further, the upper and lower positions of the tooth mold 12c can be adjusted in the groove 12a.

The tooth mold 12c has a protrusion 12p having a lower surface similar to a bamboo knot.
The lower surface of the tooth mold 12c has a curved shape that protrudes downward in the width direction. The curvature radius r thereof is, for example, 130 mm, and the main body portion of the aluminum profile A or the central portion 11a of the lower mold 11 is formed. It is smaller than the bending radius R (500 mm). The width w of the tooth mold 12c is also smaller than the width W of the main body portion of the aluminum profile A and the central portion 11a of the lower mold 11.

FIG. 4 shows a processing method for forming a node in the aluminum shape A by pressing the aluminum shape A between the lower die 11 and the pressing die 12.
When the aluminum mold A is pressed by the pressing mold 12, the tooth mold 12c bites into the back surface of the aluminum mold A, and the synthetic resin lower mold 11 is deformed in accordance with the applied pressure, so that the convex protrusion 12p is formed. Pressure deformation in the direction protruding from the surface of the aluminum profile A occurs. At this time, since the presser mold 12b holds the front and back of the tooth mold 12c, the aluminum profile A is not deformed before and after the tooth mold 12c. For this reason, the unevenness | corrugation of a nodal shape deformation | transformation occurs clearly.

Further, since the width of the tooth mold 12c is small and the bending radius r is smaller than the bending radius R of the body part a1 of the aluminum profile A, the central portion is more biting and the biting of both end portions is shallower, and the both end portions are shallower. The aluminum profile A is not sharply scratched.
For this reason, like natural bamboo, it is possible to obtain an appearance with a roundly curved node k.

(Wood grain aluminum profile B)
Next, a patterning method for the woodgrain aluminum profile B will be described.
The roll press 20 of FIG. 6 is an example of a press for processing the aluminum profile B into a wood grain. As long as the roll press 20 can press the material between a pair of rolls, it may be either manual pressurization or power pressurization, and the power may be various types of presses such as hydraulic pressure or pneumatic pressure. Can be used.

  A roll press 20 shown in FIG. 6 includes a toothed roll 21 and a plain roll 22. A toothed layer having a high hardness is provided on the surface of the toothed roll 21, and an uneven streak g that is an endless wood grain pattern resembling a natural texture is formed on the surface. The plain roll 22 has a smooth surface and is covered with an elastic synthetic resin layer that is difficult to be damaged by impact, such as trade name MC nylon.

  The toothed roll 21 is rotatably supported by the push-down frame 23, and the plain roll 22 is rotatably supported by the press frame 24. The push-down frame 23 can be raised and lowered with respect to the press frame 24 and can be pushed and pressed by the handle 25.

As shown in FIG. 7, when the push-down frame 23 is pushed down, the aluminum profile B is sandwiched between the upper toothed roll 21 and the lower plain roll 22 and is pressed, and the roll is rotated to form a pattern. The attachment is done. That is, by pressurization of the roll press 20, the wood pattern g is continuously formed in the longitudinal direction of the aluminum profile B.
In this roll press 20, the depth of the wood grain pattern g can be increased or decreased by adjusting the pressing force F applied to the handle 25.

  FIG. 8 shows a wood grain aluminum profile B patterned as described above. (A) As shown in the drawing, a wood grain pattern g is patterned on the surface of the aluminum profile B. As shown in FIG. 5B, the cross section of the aluminum profile B is composed of a flat main body b1 and L-shaped ribs b2 rising from both ends and extending outward. The width of the main body B1 is, for example, 100 mm, but is not limited to these dimensions.

The bamboo-like aluminum profile A shown in FIG. 5 and the wood-like aluminum profile B shown in FIG. 8 are used as materials for fences and gates.
FIG. 9 and FIG. 10 show an example of use when used as a fence. A large number of aluminum profiles A or aluminum profiles B are arranged side by side in parallel, and their upper and lower ends are fitted to the upper beam 31 and the lower beam 32. Are aligned.
As shown in FIGS. 10 (A) and 10 (B), each aluminum shape member A, B has ribs stacked on top of each other. May be combined.

(Woodgrain aluminum profile C)
Next, a patterning method for the woodgrain aluminum profile C will be described.
The roll press 40 in FIG. 11 is a press for continuously processing a woodgrain pattern on the aluminum shape C. The roll press 40 may be any type of press as long as it can continuously feed the material between a pair of rolls, but the illustrated press jack is a screw rod type. The drive type is a power drive gear transmission type.

  As shown in FIG. 11, the roll press 40 includes an upper roll 41 and a lower roll 42. The upper roll 41 is rotatably supported by the push-down frame 43 and can be raised and lowered within the press frame 44. The lower roll 42 is rotatably supported on the lower part of the press frame 44. The push-down frame 43 is pushed down by turning a screw rod jack 45. The screw rod jack 45 may be rotated manually by the handle or by power.

A gear 46 is attached to the rotation shaft of the upper roll 41, a gear 47 is attached to the rotation shaft of the lower roll 42, and idle gears 48 and 49 are engaged with these gears 46 and 47.
The idle gears 48 and 49 are supported by a moving mechanism (not shown) that ensures meshing while allowing the gear 46 to move down together with the push-down frame 43.
When power such as a motor is input to the gear 46 of the upper roll 41 by the gear transmission mechanism, the lower roll 42 is also rotated in the same direction.

  On the surface of the upper roll 41 in the roll press 40, a ridge p that is an endless wood grain pattern resembling a natural texture is formed. On the surface of the lower roll 42, a groove h that is an endless wood grain pattern is formed. These ridges p and ridges h have shapes that fit together.

As shown in FIG. 12, when the push-down frame 43 is pushed down by the screw rod type jack 45, the aluminum profile C is sandwiched between the upper roll 41 and the lower roll 42 and pressed, and the upper and lower rolls 41, 42 are rotated. By doing so, patterning is performed. That is, by pressurization of the roll press 40, a wood grain pattern is continuously formed in the aluminum shape C in the longitudinal direction.
The screw rod type jack 45 can be adjusted with a fine pressure by adjusting the screwing amount of the screw rod.

In particular, in the present embodiment, as shown in FIG. 13, the aluminum profile C is sandwiched between the convex strip p of the upper roll 41 and the concave strip h of the lower roll 42, and sharp concave and convex ridges are raised. The pattern g is three-dimensional on both the front and back surfaces, and has a highly visible design.
Also, in the figure, the convex shape p of the upper roll 41 is bitten into the back surface of the aluminum profile C, and a three-dimensional pattern is raised on the surface of the profile, but the upper roll 41 and the lower roll 42 are turned upside down. Alternatively, the three-dimensional pattern may be formed by inserting the aluminum shape member C in the opposite direction to that shown in FIG.

  FIG. 14 shows a woodgrain aluminum profile C. (A) As shown in the figure, a wood grain pattern g of wood is patterned on the surface of the aluminum profile C. Then, as shown in FIG. (B), the unevenness of the wood grain pattern g is rich in three-dimensionality raised on both sides. The cross-sectional shape of the aluminum profile C is composed of a flat main body c1 and L-shaped ribs c2 rising from both ends and extending outward. In order to prevent deformation and deterioration of the shape member, it is preferable that both end edges (a portion having a width of about 5 mm) of the main body part c1 are not patterned.

(Geometric pattern aluminum profile D)
Next, a patterning method for the geometric pattern aluminum profile D will be described.
The roll press 50 in FIG. 15 is a press for processing the aluminum profile D into a geometric pattern. The roll press 50 may be any type of press as long as it can press the material between a pair of rolls. However, the illustrated press jack has a screw rod type and a drive type. It is a power drive gear transmission type.

  As shown in FIG. 15, the roll press 50 includes an upper roll 51 and a lower roll 52. The upper roll 51 is rotatably supported by the push-down frame 53 and can be raised and lowered within the press frame 54. The lower roll 52 is rotatably supported on the lower part of the press frame 54. The push-down frame 53 is pushed down by turning a screw rod type jack 55. The screw rod jack 55 may be rotated manually or by power.

A gear 56 is attached to the rotating shaft of the upper roll 51, a gear 57 is attached to the rotating shaft of the lower roll 52, and idle gears 58 and 59 are engaged with these gears 56 and 57. The idle gears 58 and 59 are supported by a moving mechanism (not shown) that ensures the meshing while allowing the gear 56 to descend when the gear 56 descends together with the push-down frame 53.
When power such as a motor is input to the gear 56 of the upper roll 51 by the gear transmission mechanism, the lower roll 52 is also rotated in the same direction.

  Two types of geometric convex patterns p1 and p2 are formed on the surface of the upper roll 51 in the roll press 50. On the surface of the lower roll 52, two types of geometric concave patterns h1 and h2 are formed. The convex patterns p1 and p2 and the concave patterns h1 and h2 are shapes that fit together.

As shown in FIG. 16, when the pressing frame 53 is pressed down by the screw rod type jack 55, the aluminum profile C is sandwiched between the upper roll 51 and the lower roll 52 and pressed, and the upper and lower rolls 51, 52 are moved. Patterning is performed by rotating. That is, the geometric pattern is intermittently or continuously formed on the aluminum profile D by the press of the roll press 50.
Note that the screw rod jack 55 can be finely adjusted by adjusting the screwing amount of the screw rod.

In particular, in the present embodiment, as shown in FIG. 17, the aluminum profile D is sandwiched between the convex patterns p1 and p2 of the upper roll 51 and the concave patterns h1 and h2 of the lower roll 52, so that sharp irregularities are raised. The geometric patterns g1 and g2 are three-dimensional on both the front and back surfaces, and the design is highly visible. In the illustrated embodiment, the geometric patterns g1 and g2 appear alternately in the longitudinal direction and the lateral direction of the aluminum profile D.
Also, in the figure, the convex patterns p1 and p2 of the upper roll 51 are bitten into the back surface of the aluminum profile D, and a three-dimensional geometric pattern is raised on the surface of the profile, but the upper roll 51 and the lower roll 52 may be arranged upside down, or an aluminum shape D may be inserted upside down from the illustration to form a three-dimensional pattern in which the surface of the shape is recessed.

  FIG. 18 shows a geometric pattern aluminum profile D. (A) As shown in the figure, geometric patterns g1 and g2 are patterned on the surface of the aluminum profile D. Then, as shown in FIG. (B), the unevenness of the geometric patterns g1 and g2 is rich in three-dimensionality raised on both the front and back surfaces. The cross-sectional shape of the aluminum profile D is composed of a flat main body d1 and L-shaped ribs d2 rising from both ends and extending outward. In order to prevent deformation and deterioration of the shape material, it is preferable that both end edges (a portion having a width of about 5 mm) of the main body part d1 are not patterned.

The wood-like aluminum profile C and geometrical pattern aluminum profile D manufactured as described above are used as materials for fences, gates, and the like.
19 and 20 show an example of use when used as a fence. A large number of aluminum profiles C or aluminum profiles D are arranged in parallel, and their upper ends and lower ends are fitted and aligned with the upper beam 31 and the lower beam 32.
Further, as shown in FIG. 20, each of the aluminum shapes C and D may be bonded to a body edge or a crosspiece with a fitting ring 33 formed on one rib, with ribs overlapped with each other.

  In addition, it is also possible to use together with an aluminum shape without a pattern besides using only the aluminum shapes C and D with a pattern as mentioned above. In this case, the patterned aluminum shapes C and D become design accent members.

(Other embodiments)
In each of the above embodiments, one type of pattern is formed on one aluminum profile, but two or more types of patterns may be formed on one aluminum profile. In this case, after patterning the aluminum profile halfway with one type of press press or roll press, another pattern may be applied through the aluminum profile to another press. In this way, two types of patterns can be formed on the aluminum profile. Similarly, if three or more types of presses are used, three or more types of patterns can be formed.

  The roll press 20 shown in FIG. 6 can change the depth and height of the patterned unevenness by changing the pressing force applied to the handle 25. In the roll press 40 shown in FIG. 11 and the roll press 50 shown in FIG. The same is true, and the depth and height of the ridges for patterning can be arbitrarily changed by changing the pressing force by hand or power.
