Patent Document 1 is known as such an artificial flower made of metal. In the metal-manufactured flower figurine of Patent Document 1, the petal portion and the flower core portion formed by punching a thin metal plate into a predetermined shape are overlapped, and a thin metal body is provided in the petal portion and the flower core portion. It is attached to the hole to form a petal body. With such a configuration, the petal body can be easily manufactured.

Utility Model Registration No. 3116729

As described above, in the metal production flower figurine of Patent Document 1, a petal body can be easily produced. However, since this petal body is simply a die-cut metal plate, it has a flat shape and lacks a three-dimensional effect.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for producing a metal-produced flower having a three-dimensional effect in an easy process.

In order to solve the above problems, in one of the preferred embodiments of the method for producing a metal-produced flower according to the present invention, there is a petal plate body creating step of creating a plurality of similar petal plates made of a thin metal plate. , The plurality of petal plates are stacked upward in order from the largest one, and the fixing step for fixing the centers of gravity in a plan view and the petal shape by raising the peripheral portion in order from the petal plate located at the top. The petal shape forming step is provided, and in the petal plate body making step, a concave portion recessed inward is formed on the peripheral edge portion of the petal plate body, and the concave portion is lifted upward in the petal shape forming step. The peripheral portion is raised by applying force in this way.

In one of the preferred embodiments of the method for producing a metal-produced flower according to the present invention, an insertion hole is formed in the center of gravity of each petal plate body in the petal plate body preparation step, and in the fixing step, the insertion hole is formed. The centers of gravity are fixed to each other by a rod-shaped member inserted into the insertion holes of the plurality of petal plates that are overlapped with each other.

According to the method for producing a metal-produced flower according to the present invention, it is possible to produce a metal-produced flower having a three-dimensional effect by a simple process.

It is a figure which shows the artificial flower produced by the metal production flower production method which concerns on this invention. It is a flowchart explaining the flow of the method of making a metal production flower which concerns on this invention. It is a top view of the petal plate body in an embodiment. It is a figure which shows the manufacturing process of the metal manufacturing flower in an embodiment. It is a perspective view of the metal production flower in the middle of production in an embodiment.

FIG. 1 is a diagram showing an artificial flower (hereinafter referred to as an artificial flower) produced by the method for producing a metal-produced flower according to the present invention. As shown in the figure, in this embodiment, the artificial flower F imitates a rose and is composed of a plurality of petals.

Hereinafter, a method for producing a metal-produced flower according to the present invention will be described using the flowchart of FIG. First, a plurality of petal plates 1 are created from a thin copper plate (# 01). In this embodiment, as shown in FIG. 3, five petal plates 1a, 1b, 1c, 1d, and 1e are created. Further, as shown in FIG. 3, the petal plates 1a, 1b, 1c, 1d, and 1e are substantially similar to each other, and their sizes are slightly different. In this example, the petal plate 1a is the largest, the petal plates 1b, 1c, and 1d are gradually reduced, and the petal plate 1e is the smallest. In the following description, when it is not necessary to distinguish each petal plate body 1a, 1b, 1c, 1d, 1e, it is referred to as petal plate body 1.

As shown in FIG. 3, the petal plate body 1 in the present embodiment has a substantially pentagonal shape with rounded corners, and recesses 11 recessed inward from the peripheral edge portion are formed on each side. As a matter of course, the shape of the petal plate 1 is not limited to this, and can be appropriately changed depending on the shape of the flower to be imitated and the like.

Further, in the petal plate body 1 in the present embodiment, an insertion hole 12 is formed in the vicinity of the center of gravity in a plan view. The diameter of the insertion hole 12 is the same as or slightly larger than the diameter of the metal needle 2 described later.

Here, a method for producing the petal plate body 1 will be specifically described. In the present embodiment, the petal plate body 1 is made of a 0.1 mm copper plate. First, this copper plate is pickled and sulfurized. After that, the petal plate body 1 having the above-mentioned shape is produced by punching or cutting the copper plate. The shape of the petal plate 1 may be pickled and sulfurized after the shape of the petal plate 1 may be formed by sheet metal processing or the like.

Next, as shown in FIG. 3, a small insertion hole 12 is formed near the center of gravity of each petal plate 1 in a plan view (# 02). Then, as shown in FIG. 4, the petal plates 1a, 1b, 1c, 1d, and 1e are overlapped so that the insertion holes 12 are at the same position (# 03). At this time, they are stacked in order of size so that the largest petal plate 1a is at the bottom and the smallest petal plate 1e is at the top. Then, as shown in FIG. 4A, the metal needle 2 (an example of the rod-shaped member in the present invention) is inserted into the insertion hole 12 from below (# 04). Note that FIG. 4A shows a state in which the plurality of petal plates 1 are superposed and the metal needle 2 is inserted into the insertion hole 12 at the same time.

When the metal needle 2 is inserted into the insertion holes 12 of the plurality of overlapping petal plates 1, the state shown in FIG. 4B is obtained. Then, an unnecessary portion of the tip of the metal needle 2 is cut, and the tip is crushed to form a retaining stopper (see FIG. 4 (c)). As a result, the vicinity of the center of gravity of the adjacent petal plates 1 in the plan view is fixed to each other (# 05). The fixation of the petal plate 1 in the present invention includes not only a state in which movement is completely restricted but also a state in which movement is restricted with play.

Next, the vicinity of the peripheral edge of the petal plate 1 is raised to form a petal shape (# 06). The petal shape is formed in order from the petal plate body 1e stacked on the top. Specifically, a force is applied so as to lift the vicinity of the recess 11 of the petal plate 1 upward. For example, the vicinity of the recess 11 may be pinched by a needle-nose pliers or the like and lifted upward, or a rod-shaped instrument such as a spatula may be pressed against the vicinity of the recess 11 on the lower surface of the petal plate 1 to push it upward (drawing). As a result, the vicinity of the recess 11 of the petal plate body 1 can be lifted upward.

Such processing is performed on the vicinity of all the recesses 11 of the petal plate body 1e, and sequentially from the petal plate body 1d to the petal plate body 1a. FIG. 5 shows a state in which a petal shape is formed on the petal plates 1e, 1d, and 1c. After forming the petal shape for all the petal plates 1, the ends of the petals (the raised part of the petal plate 1) are curved to give a rounded portion, and the rounded portion is formed. By polishing with sandpaper etc., the base material of the copper plate is exposed and shaded. As a result, the artificial flower F in FIG. 1 is obtained.

[Another Embodiment]
(1) In the above-described embodiment, the insertion hole 12 is formed in the petal plate body 1, and the vicinity of the center of gravity of the petal plate body 1 is fixed by the metal needle 2 inserted through the insertion hole 12, but the fixing method is limited to this. Other methods may be used instead of being used. For example, it is also possible to fix the vicinity of the center of gravity of the two overlapping petal plates 1 with an adhesive or the like without forming the insertion hole 12 in the petal plate 1.

(2) In the above-described embodiment, a force is applied in the vicinity of the recess 11 of the petal plate body 1 when forming the petal shape, but a force may be applied to other portions.

The present invention can be used for the production of metal-producing flowers.
