[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing 18-karat gold bell bells, which is relatively simple to manufacture, inexpensive, inexpensive, can realize light weight without sacrificing tone, and has no variation in quality.
[0002]
[Prior art]
Fonn is a bell that resembles a metal wine glass and is placed on a bell pillow and strums. The sound of the tone is unique, and it is characterized by a tone that resonates and has a long tail. Fossil bells are generally made of brass, but there are 18-karat gold products. Hereinafter, a conventional method of manufacturing 18-karat gold bell bell will be described with reference to FIGS. 6, 7, 8, and 9. FIG.
[0003]
The material is 18 gold. First, the disk-shaped plate 21 is prepared (see FIG. 6). As the disk-shaped plate 21, a plate having a thickness of about 2 mm or more is used. The reason why such a thick material is used is that a bell made of a thick board resonates and resonates, giving a sound with a long tail, but a bell made of a thin board does not sound at all, so it is called a chain. The bell does not sound, it just makes a bang. The disc-shaped plate 21 is hit with a hammer, and the center is thinned and the outside is thickened to form a disc-shaped concave plate 22 (see FIG. 7). Next, the disc-shaped concave plate 22 is hit with a hammer to deform it into a shape similar to a wine glass, thereby forming a bowl-shaped body 23 (see FIG. 8). When the disc-shaped concave plate 22 is deformed into a bowl-shaped body 23, the thickness of each part increases. This is because when the thick plate is flexed, the inside thickness becomes remarkably enlarged. Next, in order to remove the corners of the bowl-shaped body 23 and to shape the whole, the whole body is shaved to complete the fountain 24 (see FIG. 9). Although the external dimensions such as the height and the maximum diameter of the fountain 24 at the time of completion are the same as those of the bowl-shaped body 23, the thickness is smaller than that of the bowl-shaped body 23 due to the shaving process. The shape of the bell 24 after shaving is the thinnest at the center, the thickness is thinner than the thickness of the disc-shaped plate 21, and the thickness from the side to the edge is larger than the thickness of the disc-shaped plate 21. It has a thickness of about 5 mm or more from the side surface to the edge portion of the bell. This is an indispensable shape so that Fosuzu 24 can sound with a good tone. The thick U-shaped cross-section of this side works like a tuning fork, and can produce the unique sound of Fosuzu. It is.
[0004]
A concrete example of the above-mentioned conventional method of producing a bell bell will be described with numerical values. First, a disk-shaped plate 21 having a thickness of 5.0 mm is made of 18-gold. The diameter of the disk-shaped plate 21 is 150 mm and the weight is 700 g. Next, the disc-shaped plate 21 is hit with a hammer, and the center is thinned and the outside is thickened to form a disc-shaped concave plate 22. At this time, the disc-shaped concave plate 22 having a diameter of 150 mm has a central thickness reduced to 0.7 mm and an edge portion increased to 5.0 mm. Next, the disc-shaped concave plate 22 is hit with a hammer, and the plate-shaped concave plate 22 is deformed into a wine glass shape without legs, thereby forming a bowl-shaped body 23. At this point, the bowl 23 has a height of 48 mm at the highest point and 90 mm at the widest point. The thickness of the bowl 23 is increased by bending, the center at the bottom is 2.0 mm, and the raised edge is 6.0 mm. become. Next, the corner of the mouth of the bowl-shaped body 23 is cut and the whole is shaved in order to adjust the whole shape. The finished bell 24 is 48 mm at the highest point and 90 mm at the widest point. The outer dimensions are the same as the bowl 23, but the thickness is 1.2 mm at the center and 5. mm at the edges. It has changed to 0 mm. Since 300 g is reduced by shaving, the weight of the completed Fonn 24 will be 400 g.
[0005]
[Problems to be solved by the invention]
The above-described conventional 18-karat gold bell manufacturing method has the following four problems. First, it is not easy to manufacture. Striking the disc-shaped plate 21 to make the edge thicker and the center thinner is an operation requiring considerable labor and time. Next, it takes considerable labor and time to form the bowl-shaped body 23 by deforming while hitting the disc-shaped concave plate 22 having a thick part and a thin part depending on the place. Further, as a final finish, in order to adjust the shape of the bowl-shaped body 23, unnecessary portions must be completely removed from almost the entire bowl-shaped body 23, which is also a work requiring considerable labor and time. Second, the cost is high. It takes a lot of 18k gold to make one bell. For this reason, 18-karat gold bells are expensive and hardly popular. Third, the weight is large. If a large amount is cut to reduce the weight and the overall thickness is reduced, the sound will not be heard. There is no resonance, just a short bang like a bang on a metal plate. In this case, it would not be possible to say that it was a bell, so there was a limit to reducing the weight of the bell. Fourth, it is difficult to maintain uniform quality. Since all processes involve work involving a change in thickness, individual processes are slightly different from the overall balance, and variations among products are likely to occur. In fact, when I sounded several bells made with the same manufacturing method, they often had slightly different tones.
[0006]
An object of the present invention is to provide a method of manufacturing a bell bell which can solve all the above-mentioned problems.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention uses an 18-metal bullion as a material in the manufacture of Fossu bells, and has a thickness of 0.63 mm or more and 0.8 mm or less, which is a material for constituting the main body of the Fossu bells. For forming a disc-shaped plate and a mouth portion of a fountain, having a width of not less than 6.8 times and not more than 9.5 times and a thickness of not less than 4.2 times and not more than 6.6 times the thickness of the disc-shaped plate. By making a ring-shaped plate having a thickness and hitting the disc-shaped plate with a hammer, the center is curved downward and projected, and the side surface is curved up and deformed so that the edge portion faces upward. The bowl-shaped main body constituting the main body portion is formed, and the edge portion of the upper end of the bowl-shaped main body and the lower outer side of the ring-shaped plate are attached together over the entire circumference. The fountain is characterized by being finished with a shaving process to smooth out the surface A manufacturing method.
[0008]
According to the above invention, firstly, the manufacture is very simple. This is because there is no work to change the thickness in all the steps, so that the labor required for manufacturing is small, and the working time can be shortened accordingly. Second, manufacturing costs are low and prices can be sold at low prices. The amount of 18 gold required to produce a single bell at the material stage is about one-third the conventional amount. Third, the weight can be reduced without sacrificing the tone. The main body alone is too thin to produce sound, but the thick mouth above the main body allows it to resonate in the same way as a tuning fork. Can produce a sound that resonates. Comparing the weight of the completed Fossil, it is about half of the conventional weight. Fourth, quality variations can be eliminated. This is because the work of tapping and deforming does not include a step of changing the thickness to create a subtle individual difference. For example, when the disk-shaped plate is processed into a bowl-shaped main body, the thickness of the disk-shaped plate is small, so that the thickness of the disk-shaped plate does not increase. In the present invention, "the center is curved downward and the side is curved and the side is curved and deformed so that the edge portion faces upward" means that a flat disk-shaped plate is rounded and a wine glass shape is formed. It means that it is processed into a bowl-shaped body. In order to achieve the above, if the thickness of the disk-shaped plate is larger than the above-mentioned dimensions, the thickness will be greatly increased when processing into a bowl-shaped main body, and if it is thin, the strength will be insufficient. Then, optimal conditions for the width and thickness of the ring-shaped plate could be obtained from the relationship with the thickness of the disk-shaped plate. If the width of the ring-shaped plate is longer than the above-mentioned dimensions, the appearance of the bell will be lost, and if it is short, the resonance of the tuning fork will be lost and the sound unique to the bell will not be produced. If the thickness of the ring-shaped plate is larger than the above-mentioned size, the cost of 18K is wasted and its weight is wasted. If the thickness is thin, the resonance effect of the tuning fork is lost and the sound peculiar to Fossil is not produced. The diameter of the disk-shaped plate is adjusted according to the size and shape of the bell to be manufactured.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the method of manufacturing a bell bell according to the present invention will be described with reference to FIGS. 1, 2, 3, 4, and 5, but the present invention is limited to only the following embodiments. Needless to say, it should not be.
[0010]
The material is 18 gold. In this embodiment, it is 18 gold having a ratio of gold 18: silver 4.8: copper 1.2. First, the disk-shaped plate 2 and the ring-shaped plate 4 are prepared. The total weight of the 18-piece gold including the disc-shaped plate 2 and the ring-shaped plate 4 is 250 g. The disk-shaped plate 2 is a material for constituting the main body portion 1 of the bell bell 6 at the time of completion, and has a diameter of 150 mm and a thickness of 0.63 mm or more and 0.8 mm or less. 0.7 mm. The ring-shaped plate 4 is a material for constituting the mouth portion 3 of the bell bell 6 at the time of completion, and has an outer diameter of 86.0 mm, an inner diameter of 76.0 mm, and a width (width of a ring band) of the disk-shaped plate 2. In the present embodiment, the thickness is 5.0 mm, which is about 7.1 times, and the thickness is 4.2 times or more, 6.6 times the thickness of the disc-shaped plate 2 within the range of 6.8 times to 9.5 times the thickness of the disc 2. In the present embodiment, the distance is about 4.3 times 3.0 mm within the following range. Next, the disc-shaped plate 2 is hit with a hammer (not shown) so that the center is curved and protruded downward to form a bottom, and the peripheral portion is raised in a phased manner to form a side surface so that the edge portion faces upward. Processing. Thus, a bowl-shaped main body 5 having a shape similar to a rounded wine glass is formed. The outer diameter of the ring-shaped plate 4 and the outer diameter of the edge portion of the bowl-shaped main body 5 are previously adjusted to match the outer diameter of the mouth portion 3 of the bell 6 at the time of completion. The dimensions of the bowl-shaped main body 5 are as follows: the maximum diameter is 90.0 mm, the outer diameter of the edge portion is 86.0 mm, the height is 45.0 mm, the thickness is 0.7 mm at the center bottom, and the edge portion is 0.7 mm. . Next, the edge portion of the upper end of the bowl-shaped main body 5 and the outer side of the lower portion of the annular plate 4 are attached together over the entire circumference. Since both sides are heated and joined together, the bowl-shaped main body 5 and the ring-shaped plate 4 are completely integrated. After the attachment, a shaving process is performed on the ring-shaped plate 4 integrated with the bowl-shaped main body 5 to eliminate corners and to smooth the surface. With the above, Fo Suzu 6 is completed. The size of the bell is as follows: the maximum diameter is 90.0mm, the outer diameter of the mouth part 3 is 86.0mm, the height is 48.0mm, the thickness is 0.7mm at the bottom of the center of the body part 1, and the thickness of the body part 1 The side surface is also 0.7 mm. The whole is rounded, and the upper part is slightly curved inward to improve the tone.
[0011]
There are several sizes of the bell, and the bell 6 described in the above embodiment has a typical maximum diameter of three dimensions, that is, 90.0 mm. Other than this, for example, a fountain with a maximum diameter of 2 dimensions 5 minutes, that is, 75.0 mm (the thickness of the disc-shaped plate 2 is suitably about 0.63 mm) or a 3 dimensional 5 minutes, that is, 105.0 mm (Approx. 0.8 mm is appropriate for the thickness of the disk-shaped plate 2). According to the present invention, the above-mentioned fountain bells and various other sized bells can be manufactured by solving the conventional problems. The diameter of the disk-shaped plate 2 is adjusted according to the size and shape of the bell to be manufactured.
[0012]
【The invention's effect】
According to the above invention, firstly, the production is very simple, the labor required for the production is small, and the working time can be shortened accordingly. Secondly, the manufacturing cost is low and it can be provided at a low price. The major factor is the reduction in material costs, and the 18-karat gold required at the material stage can be reduced to about one-third of the conventional cost. Third, it is possible to reduce the weight while securing the tone that resonates with Fosling's unique chain. It is about one half the weight of conventional Fossil. Fourth, uniform quality Fossil can be easily manufactured. By repeating the same manufacturing process, the bell of the same tone can be easily manufactured.
