Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes precision automatic fusing technology to reduce the thickness of approximately 110 mm.
- Regarding new methods for manufacturing nameplates, signboards, ornaments, and various other decorative items using large and small thick steel plates such as 150i, stainless steel, and other metal plates, especially decorations made from the above metal plates. As objects, etc., it is a profound and elegant artistic item that cannot be seen at all in conventional two-dimensional ornaments or three-dimensional ornaments made of cast metal, etc., and moreover, it is simpler and easier to use than cast objects. The purpose is to provide something.

The method of the present invention will be described in detail below based on the illustrated embodiment. Reference numeral 1 denotes a gauge plate made of a thin plate made of synthetic resin, at least one surface of which is formed as a rough surface 2 of satin finish or the like. In addition to ensuring the supporting and supporting movement of the roller in the copying device which will be described later, the following intended font or figure A is directly exposed on the rough surface 2 side.

That is, Fig. 2 shows an example of what is expressed in the font A, and if we adopt, for example, the character a of the kanji ``Makoto'' as shown in Fig. 1 as the font A, then this In order to make it appear on the rough surface 2 of the gauge plate 1, it is necessary to use "
The letter a, ``Makoto,'' is converted into a single font A, ``Makoto,'' which has a continuous outline, such as a so-called cursive typeface as shown in FIG.

In other words, by comparing the font A in Figure 2 with the letter a in Figure 1, set an arbitrary point as the starting point 3, start writing from the same starting point 3, and write ``Makoto'' - the outline of the letter a. In order to allow continuous progress along the line and ultimately return to the starting point 3 above, the font A is used to avoid passing through the same route again. Therefore, in this case, the first For the letter a in the so-called instrumental font as shown in the figure,
Since there are mutually separated parts 4 among the constituent elements, in such a case, adjacent constituent elements are interconnected by intervening suitable connecting pieces 5, and the letters as shown in Fig. 1 are used. In a, the blockage part 6 (named ``Makoto'') by its constituent elements refers to the part corresponding to ``mouth'' in the character.

), a part of the peripheral frame that forms the closed part 6 is cut to form the opening 1, and through such expressive operations, the font A, which can be written in one stroke, as shown in Figure 2, is created.
It is expressed as.

Therefore, such a font A has a predetermined width due to a continuous contour.

In this case, in Figures 1 and 2, the target font A is one character a.
Although we have shown the fonts that are converted and expressed from The same applies to cases where a figure or multiple figures are used as a figure for producing a family crest, a painting, etc., or when a figurine or the like is produced by combining letters and figures.

Furthermore, although FIG. 2 shows a method for directly displaying the font A on the rough surface 2 of the gauge plate 1, as long as at least one surface of the plate 1 is made into the rough surface 2, the method shown in FIG. A gauge plate that directly expresses a target font or figure A on an original plate 8 made of a material other than the gauge plate 1 such as paper, cloth, etc., and allows the font or figure A of the original plate 8 to be seen through transparent or translucent. The font A may be indirectly exposed on the gauge plate 1 by making it visible from above the gauge plate 1.

The font A that has been exposed on the gauge plate 1 through the first step is then used with the following copying tool and the same copying tool in order to trace the outline of the font A from the rough surface 2 of the same plate 1. The metal material is cut along the predetermined width of the font A by a gas jet from an automatic fusing machine that works in conjunction with the copying tool.

That is, Fig. 4 shows an automatic gas jet m cutter,
Reference numeral 9 denotes a copying tool supported at the upper protruding end of the substantially U-shaped arm 10. In the example shown, the copying tool 9 is pivotably mounted as a roller of a set of casters, and can be moved up and down by a rack gear or the like. It is said that it can be adjusted freely.

Reference numeral 11 indicates a motor, and reference numerals 12, 13, and 14 indicate a power cord, a power switch, and a reverse switch provided on the arm 10, respectively.

Further, 15 is a blowpipe supported by the lower protruding end of the arm 10, and 16 is a crater occupying the lower part of the blowpipe 15, and these blowpipe 15 and crater 16 are also set to be able to adjust vertical movement by means of rack gears, etc. .

Reference numerals 17 and 18 are knobs for selecting the vertical movement of the copying tool 9 and the nozzle 16; 19 is a hose for supplying gas, oxygen, etc. that communicates with the blowpipe 15; 20 is a fixing knob for the arm 10; 21
is a support frame for the arm 10, one end of which is swingably pivoted to the support 23 of the installation base 22, and the other end pivoted to the base of the arm 10. This allows the arm 10 to swing around the vertical axis.

The metal material on the installation stand 22 is about 10
- A steel plate, stainless steel or other metal plate 23 of a predetermined size with a wall thickness of 150 ut is placed on the table 24 installed on the top of the installation stand 22. After setting the gauge plate 1 with the font A displayed on it, place it on the table 24 and hold the nearby supporting part of the copying tool 9 with your hand. Also, while controlling the speed and direction rotation of the automatic gas jet cutting machine, the roller serving as the copying tool 9 is moved along the continuous outline of the font A on the gauge plate 1 in a so-called brush stroke manner. Let it proceed.

At this time, an ultra-high temperature gas jet ejected from the nozzle 16 of the fusing machine in conjunction with the roller serving as the copying tool 9 also accompanies the installation stand 2 below the table 24.
The metal plate 23 on 2 is cut in a single stroke, as if the gas jet were to follow the continuous outline of the font A, and therefore no cut-off pieces or the like would be produced.

At this time, since the roller as the copying tool 9 is moved by lowering the liquid onto the rough surface of the gauge plate 1, the copying tool 9 can be moved along the font A accurately.

In particular, when copying the so-called raised edge part a of the font A as shown in FIGS. 7 and 8 with the copying tool 9, as shown in FIG.
When the copying tool 9 is simply advanced in the direction of the arrow X along the contour of the edge portion a as in 1), the semi-finished product B obtained by cutting the armor will be located at the edge portion as shown in the same figure (If). The disadvantage is that the edges are rounded, making it impossible to obtain a predetermined sharp edge shape.

On the other hand, as shown in Figure 8 (1), the edge part a of font A
As shown by the arrow Y, after moving the copying tool 9 away from the font A at the sharp end of the edge part a, move it in a circle so that it faces the sharp end again, and you will get a stepping stone. It is desirable that the semi-finished product B has a very sharp edge shape as shown in the same figure (If).
In order for the gauge plate 1 to move quickly and along a complicated course as indicated by the arrow Y, it is essential to make the surface of the gauge plate 1 rough, and only then can the sharp edges be obtained.

In this case, as is clear from FIG. 4, the gas jet sprayed from the nozzle 16 of the fuse cutter is projected from the vertical direction onto the metal plate 23 placed horizontally on the installation stand 22. Therefore, the metal plate 23 is cut in the vertical direction.

In addition, in FIG. 4, the copying tool 9 and the tip 16 supported by the upper and lower projecting ends of the substantially U-shaped arm 10 are arranged on the same vertical line. By changing the length of the arm 10, etc., copying work and cutting work may be performed at different positions above and below, or the font A on the gauge plate 1 may be
It may also be possible to perform a cutting operation of the gas jet such that ζψ11 is proportionally expanded or contracted with respect to the copying operation of the copying tool 9 along the line.

The semi-finished products made from the metal materials cut in this way are as shown in Figure 5.

That is, FIG. 5 shows an example of a semi-finished product B4 cut along the font A of the ``Makoto'' right Ryuichi character in FIG. If we look closely at the plane B1 and the horizontal plane B2 that intersects with it, we can see that the vertical plane B1 along the outline of the font A has the following shapes, as shown in Figure 6.
A large number of parallel streak groups 25 along the vertical direction are generated by the jet projected from the vertical direction of the metal plate 23.

On the other hand, on the horizontal plane B2 along the predetermined width of the font A, a continuous protrusion 26 is created that bulges upward along the cutting contour of the gas jet, thereby making the cross-sectional shape of the semi-finished product B approximately concave. Eggplant.

Therefore, in the present invention, next, for such semi-finished product B,
The surface of the low protrusion 26 with a height of about 0.5 to 1 mm generated on the horizontal plane B2 and the depression surrounded by the protrusion 26 is polished to form a flat surface lζ, and then the vertical While leaving the group of parallel streaks 25 generated on the surface B1, various surface treatments such as plating and coloring are applied to the entire semi-finished product B to manufacture a finished product such as a decorative item.

In this case, as a means for polishing the surface of the semi-finished product B, for example, polishing with a sander or paper is used, and as a surface finishing method, plating with chrome, gold, silver, etc., application of a plastic film, etc. are used.

As mentioned above, in the present invention, for example, when one letter a is adopted as the figure or font A of the intended ornament, etc., the constituent elements of the letter a are the connecting piece 5, the opening lower, etc. 1. The special font A is always connected in at least one place through the font A, and the copying tool 9 follows the special font A, so to speak, in one stroke. Since the metal material is cut by the gas jet linked with this, decorations etc. made of large and small steel plates, stainless steel, and other metal plates 23 with thicknesses of about 10 to 150 mg are obtained. This can be easily carried out by utilizing the precision automatic cutting technology, and the ornaments etc. manufactured by this method have an exposed metal surface due to the remaining parallel streaks 25, and express elegance. In addition, since the copying tool 9 is advanced on the rough surface of the gauge plate 1, it is possible to obtain not only an accurate product that follows the font A, but also a sharp machining part that follows the edge part a of the font A. It is possible to easily manufacture a product with a surface finish such as chrome plating on the base to create a beauty that suits your taste, as well as the thickness of the metal material as described above. , it is worthy of being evaluated as a kind of art that cannot be seen in conventional flat ornaments or cast ornaments, and moreover, it is much easier to obtain than cast objects etc. .

Therefore, if a combination of multiple letters is adopted as the above font A, the finished product can be used as it is for nameplates, signboards, etc., and if a graphic font is adopted, the decoration can be placed in a frame or in a box. It is a versatile decoration that can be used as a gift or souvenir, for example, by combining the font A with a pedestal using the above method and using the decoration as a figurine. This is a new and excellent invention for practical purposes as it allows you to obtain things.
