Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method 31 for manufacturing a profile for a decorative frame and to a decorative frame.

Aluminum or its alloys have traditionally been used for the interior and exterior of picture frames, office machines, electrical appliances, furniture, automobiles, vehicles, ships, aircraft bridges, buildings such as houses, and structures such as window sashes and door sashes. A long material, usually about 4 to 6 meters long, whose entire surface is flat, is formed by extrusion or roll-forming, and the surface is treated with anodized coating or other anti-corrosion treatment, either uncolored or colored. I know of one that is cut to the appropriate length and assembled into an n'2 rectangular frame, but its surface has a silvery white characteristic of aluminum or a flat colored camellia oxide film surface. Or, it is limited to having a monotonous decorative surface colored by electrodeposition coating.

The present invention eliminates such a flat and monotonous surface decoration, increases the decorative effect of partially having glittering and directional striations on its surface, and increases its commercial value by 1. The present invention provides a method for easily and cost-effectively manufacturing a mold material, in which at least a protrusion having an appropriate cross-sectional shape extending along its longitudinal direction is formed on the surface by extrusion or roll-forming of aluminum or its alloy material. 1. Molding a shape material of an appropriate length to be sold, cutting or grinding the surface of the protrusion of the long shape material with a high-speed rotation of a cutting tool, grindstone, etc., and cutting or grinding the surface of the long shape material in the width direction or length direction of the long shape material. Is it possible to process a surface with bright striations consisting of countless cutting or grinding striations with a directionality running along the surface? It is characterized by comprising the steps of anodizing and sealing with or without dyeing, and cutting at the required length and angle to form a predetermined frame component.

Furthermore, according to the present invention, each pair of left and right sides and upper and lower sides of the surrounding frame have the same directionality of their countless striations, and the projection and reflection directions of natural light rays for each pair differ by 90 degrees from each other. It provides a decorative frame with uniform strength and decorative effect, and it is machined into a bright cut decorative surface consisting of countless striations with the same direction, with fewer protrusions having an arbitrary cross-sectional shape. Both are assembled into a J-shaped enclosure by the enclosure component side.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

A large number of long shapes ranging from 4 to 6 meters are made from aluminum or alloy material by extrusion or roll-forming. The cross-sectional shape differs depending on the
In each molding, at least one protrusion (2) is formed on the surface (1) of the surface (1), which has a desired cross-sectional shape and extends in the longitudinal direction in a part thereof, protruding upward from the base surface (la). A long shaped material a is manufactured. The examples shown in Figures 1 and 2 are for window sashes, and the example for door sashes. The example shown in Figure 3 is for decorative edges such as picture frames. 1 The cross-sectional shape of the ridges (2) can be arbitrary, such as square, triangle, trapezoid, etc. .

Therefore, the upper surface (2a) is parallel to or inclined to the base surface (la).

For convenience of explanation, the process of this method will be explained for the elongated material a shown in the first figure. For the long mold a thus prepared, the flat upper surface (2a) of the protrusion (2) was cut over its entire length by horizontal high-speed rotation of a diamond cutting tool, as shown in Fig. 4A. As shown, the protrusion (2) is processed into a glittering streak surface (2a') consisting of countless cutting streaks (3) running in the width direction and having glittering properties. Alternatively, instead of a diamond cutting tool, a rotary grinding wheel may be used, and its high-speed rotation in the vertical direction may cause the flat surface (2) of the protrusion (2) to be sharpened.
a) 'fr: Brilliant syllables that are grinded over the entire length and are made up of countless grinding marks (3) running in the length direction of the protrusions (2) as shown in Figure 4B, and that have glitter properties. It is processed into a striated surface (2a'). Next, after that, the entire surface of the remaining shape material, including the striped surface (2a'l f) of the long shape material a that has been partially cut or ground, is anodized to form an anodic oxide film (4) on the entire surface as shown in figure F5. The striated surface (2+I') may be left uncolored in chrome color, but if necessary, it may be dyed in a suitable color, such as gold or bronze by metal salt coloring, or electrolytically colored.

It may also be colored. Thereafter, the hole is punctured using a conventional method. In this way, a decorative frame member a' according to the present invention is obtained. In this way, since the long profile af was formed in advance so that the surface (1) has the protrusions (2) in its length direction, a cutting or grinding tool having a rotating surface in the horizontal or vertical direction can be attached to the surface. When applying it to the side, only the forward rotation (2a) of the protrusion (2) is automatically cut or ground, and the surface area lower than this is automatically cut or ground. ), there are countless regularly spaced striations (3
) can be formed on the bright streak surface (2a).If necessary, the streak surface (flat surface other than 2a'1 ( la)
The entire surface of the mold material a including 'fr' (2a may be formed on a colored surface of a different color from that of the other surface).

In this case, when applying nuclide to a metal surface by painting, it is best to apply a hard impression of bright streaks (in contrast to the metallic luster surface of 2a'1), a soft impression of a non-metallic painted surface can be applied. can.

As an illegal modification example, before processing the above-mentioned protrusion (2) into a bright streak surface (2a'), a long profile material aK is
The anodic oxidation treatment may be performed nine times over the entire surface. In this case, the anodic oxide film is completely removed by cutting or polishing the top surface (2a) of the protrusion (2), so after forming the bright streak surface (2a'l), this surface is anodized. Film (4
) Fully formed, and then fully sealed. In addition, even in the case of the above-mentioned embodiment, the long mold can also be subjected to surface treatment such as sandblasting hairline, chemical polishing,
Pretreatment such as chemical matting may be applied to the entire surface.

The decorative enclosing frame material a' shown in FIG. This is a corrosion-resistant long profile product having a surface (2) in which a plurality of strips of 1a) run alternately in parallel to the longitudinal direction.

A desired force decoration surrounding frame is created using this material as a raw material.

In this case, if it is longer than the constituent members on one side of the decorative frame, cut it to the required length along lines that are inclined in opposite directions at both ends at an angle of 45°. The example shown in Figure 5 shows an example of a picture frame, and is an illegal long decorative frame material a'? Cut the components at equal intervals as described above, prepare all the components for the four picture frames, and place them on the opposite sides of the 45° inclined end faces of each of the two square surrounding frames. The decorative surrounding picture frame B of the present invention is manufactured by connecting the two corners to each other from the inside with a connecting piece or adhesive.

In this manner, the countless streaks (3) formed on the surfaces of the protrusions (2) of the pair of left and right constituent members a/, a/ of the picture frame B as a result of such assembly run horizontally when viewed from the front. However, the upper and lower pair of constituent members a/.

The countless striations (3) formed on the surface of each protrusion (2) of a' are
The natural light rays that run vertically, thus hitting the picture frame, are at right angles to each other? Therefore, the left and right pairs of horizontal striations (3)... and the upper and lower vertical striations (3) reflect each other at right angles, and depending on the viewing angle, light is reflected on the bright surface. Not only does it increase the decorative effect of the decorative frame, such as giving dynamic changes, but also each of its protrusions (2
) gives a three-dimensional effect to the surrounding frame surface in relation to the flat striped surface (1b) and increases its strength. Furthermore, when the striations (the two pieces and the remaining entire surface) of each component a' are configured in different colors, the contrast can further enhance the design effect.

In addition, as shown in FIGS. 2 and 3 above, the surface (1)
When creating a decorative frame as shown in Figure 5 using a molded material ai in which the protrusion (2) is displaced to one side, its cross-sectional shape will be as shown in Figures 2 and 3. A mold is created separately using a pair of formwork members a'+a''i whose cross-sectional shapes are symmetrical, and each has a cut end face metal of 45° to a predetermined length. Create each frame,
By assembling these pieces into a full rectangular frame, various decorative frames can be obtained.

It goes without saying that it is possible to create a decorative enclosure having a frame shape other than a square by using all of the decorative enclosure frame materials of the present invention.

In addition, FIG. 6 shows that the shape material shown in FIG. 3 has at least a flat surface (2a) of the protrusion (2) having a trapezoidal cross section on its outer outer frame and a protrusion (2) having a triangular cross section on its inner frame edge. A striation surface (2a) consisting of countless cutting striations (3) parallel to the inclined surface
It was formed approximately. A similar striation surface may also be formed on the outer inclined surface of the protrusion (2) having a trapezoidal cross section.

In this way, according to the present invention, after creating a long profile material having protrusions on the surface, cutting or grinding is performed on the upper surface of the protrusions (7). Since all the striations are formed to form a bright striated surface, and the whole surface is completely treated with corrosion-resistant surface treatment, it is easy to manufacture, and its service life can be extended. In addition, the protrusions increase the strength completely, and it is possible to provide a product with a new sense of contrast between the bright streak surface and the flat surface. When constructing a rectangular enclosure using constituent members with the same directionality cut at an angle, the directionality of the luminous streaks of the six pairs of constituent members on the upper, lower, left, and right sides are mutually perpendicular to each other, and the strength and composition are balanced. This method also has effects such as a decorative frame with increased design effect.
