Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating a wooden product or the like for engraving a special surface pattern on a decoration object such as a rotary-shaped wooden product.

2. Description of the Related Art Wooden products such as bowls, trays, and wooden plates are made using a lathe for woodworking, which is a type of potter's wheel. Lacquered lacquerware is widely used in these wooden products, and the lacquerware is variously decorated.

One method of decorating lacquer ware is to apply an intermittent carving pattern in the circumferential direction.This method attaches a wooden base to the potter's wheel before applying lacquer and rotates it to give the handle part elasticity. We use a kind of engraving tool called squeeze plane.
In other words, if you hold the billiard with your hand and press the blade against the surface of the rotating wood, the billimeter will vibrate depending on the cutting angle and depth of the blade with respect to the wood, Intermittent carving scratches on the surface of the wooden ground by moving the wooden plane from the center of the wooden ground to the radial direction of the peripheral edge, or vice versa, while vibrating the wooden plane. The continuous engraving flaw can be formed continuously, and a beautiful engraving pattern such as a spiral pattern or a repeating pattern can be applied as a whole.

Problems to be Solved by the Invention According to such a conventional technique, the degree of the cutting angle and the depth of the bi-plane varies depending on whether the cutting edge of the bi-plane is applied to the surface of the wooden background, so that an unskilled person vibrates the bi-plane. There was a problem that it was very difficult to sculpt, and it required long-term experience to learn how to apply the planer. In addition, it is only possible to decorate with wood before finishing lacquer,
The finished intermediate lacquer product had a hard and smooth surface, so that no vibrating vibrations were generated, making it impossible to decorate with the vibrating surface.

Therefore, an object of the present invention is to provide a decorative material having discontinuous cutting edges on a rotating circumference, so that even an unskilled person can use lacquer ware. Another object of the present invention is to provide a decorating method for a wooden product or the like which can easily apply a carved pattern to a decorative object including an intermediate product with a base lacquer.

Means for Solving the Problems The configuration of the present invention for achieving the above object is a method of forming a carved pattern on a rotating object-shaped decoration object during rotation having a discontinuous cutting edge on a rotating circumference. The gist of the present invention is to move the decorating tool along a radial path of the decorating object while bringing the rotating circumference of the decorating tool into contact with the surface of the rotating decorating object.

In addition, the rotation speed of at least one of the decoration target object and the decoration tool can be continuously changed.

According to the configuration of the present invention, the object to be decorated having a rotating body shape is rotated around its central axis, and the rotating cutting edge of the decorating tool is brought into contact with the surface of the object to be decorated. Is brought into contact with the surface of the object to be decorated, the cutting edge discontinuously present on the rotating circumference can intermittently cut the surface of the object to be decorated and make a cut. In addition, the position of the engraving is substantially constant in the circumferential direction of the decorating object when the rotation of the decorating object and the cutting edge are in a synchronous relationship, but the rotations of both are not in a synchronous relationship. At this time, it fluctuates randomly in the circumferential direction of the decoration target.

Therefore, while the rotating circumference is in contact with the decoration target, at least one of the rotation speed of the decoration target and the cutting edge is continuously changed, and from the center of the decoration target to the peripheral edge, or When the decorating tool is moved along the radial direction in the opposite direction, the decorative object will have a beautiful repeating pattern of chevron or wavy for a certain range centered on the part where both rotations are synchronized. Is formed, and an irregular dotted-line pattern is formed in a portion that is not synchronized,
These patterns appear repeatedly in the form of stripes in the radial direction of the object to be decorated, and a beautiful carved pattern can be formed as a whole. In general, the rotation speed of commercially available pneumatic or electric drills varies greatly depending on the load.If these manual tools are used with a decorative tool installed, the rotation speed of the cutting edge will change. There is no need to use any special rotation changing means for this.

However, the “rotational circumference” here refers to a circle drawn by the cutting edge of the decorative tool when the decorative tool is driven to rotate, and the “radial path” In addition to the path in the radial direction of the object to be decorated, a path that curves in the rotation direction of the object to be decorated or in the opposite direction, a path that curves in both directions in a waveform, and the like are included.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

A method for decorating a wooden product or the like is performed using a decorating tool 10 having a processing portion 12 formed at the tip of an attachment portion 11 (first example).
Figure).

The decorative tool 10 has a round bar with a slope 12
The cutting part 12 is cut through the b to form a cutting edge 12a at the forefront of the processing part 12.

The decorating tool 10 inserts the mounting portion 11 into a chuck D1 of a pneumatic or electric drill D and is driven to rotate by the drill D (FIGS. 1 and 2). In addition, the wooden ground W which is an object to be decorated is fixed to a potter's wheel (not shown) and has a center line.
It should be rotated around Wc.

When the drill D is activated, the decorative tool 10 rotates around the axis C1 of the mounting portion 11, and the cutting edge 12a draws a rotating circumference C around the axis C1 (FIG. 1). At this time, the cutting edge 12a
Is formed only at one point at the forefront of the decorative tool 10, and is formed discontinuously on the rotating circumference C.

When the drill D is started and the rotating circumference C formed by the cutting edge 12a of the decorative tool 10 is brought into contact with the surface of the wood W (second
(FIG. 3, FIG. 3), the cutting edge 12a intermittently cuts the wooden ground W, and can make intermittently carved scratches W1, W1,.
At this time, the angle θ between the axis C1 of the decorative tool 10 and the surface of the wood W is preferably set to an acute angle.
The rotation directions of the wood W are preferably set to be opposite to each other at the contact portions between the two (for example, the directions of arrows K1 and K2 in FIGS. 2 and 3).

On the other hand, the positions of the engraved scratches W1, W1.
If the rotation of the decorative tool 10 is in a synchronous relationship, it will be at a fixed position in the circumferential direction of the wood W, but if both are not in a synchronous relationship, it will continuously fluctuate in the circumferential direction of the wood W over time. I do. Therefore, the drill D is held by hand, and the cutting edge 12a of the decorative tool 10 is held.
While maintaining the intermittent contact state between
When the decorating tool 10 is moved in the radial direction from the center to the peripheral edge, the rotation speed of the drill D changes greatly and continuously due to the cutting resistance of the decorating tool 10, and the cutting edge 12a and the wood W As a result, a portion in which the rotation of the rotation is synchronized with a portion in which the rotation is not synchronized appear alternately, so that a beautiful carved pattern can be formed on the wooden base W by the collection of the carved scratches W1, W1.

The carved scratches W1, W1 ... on the wood W are the cutting edges of the decorative tool 10.
By 12a, one piece is formed per rotation of the decorative tool 10. Accordingly, the circumferential position of the woodwork W is determined by the rotational phase of the woodwork W and the decorative tool 10. For example, when the relative rotation speed ratio between the two is an integral multiple. Since the synchronous relationship between the two rotations is maintained, the position becomes constant in time, and when the position is a non-integer multiple, the synchronous relationship is lost and the time fluctuates. Therefore, when the rotation speed of the decorative tool 10 was continuously changed, the synchronous relationship was lost in the radial direction of the wood W as a carved pattern on the wood W as shown in FIG. In addition to the set of irregular point patterns corresponding to the parts, the set of synchronized continuous patterns and the set of regular continuous patterns that look like chevron or waveform corresponding to a certain range before and after are repeated. And a beautiful decorative pattern can be formed as a whole.

At this time, the method of moving the decorative tool 10 does not require extraordinarily complicated attention.
It is sufficient to move the rotating circumference C formed by 12a in the radial direction from the center of the wood W toward the peripheral edge thereof while pressing it against the surface of the wood W (arrow Y direction in FIG. 3). However, the decorative tool 10 may be moved from the periphery of the wood W to the center, and in any case, when the rotating circumference C is pressed against the surface of the wood W to move. The pressing force is appropriately adjusted, and the surface of the wood W and the axis C1 of the decorative tool 10 are adjusted.
It is only necessary to pay attention to the fact that the angle θ with the angle is constant, the moving speed is appropriate, and the like. However, it is needless to say that these parameters may be intentionally changed.

Further, the moving path of the decorative tool 10 is a path Y2 that curves in the direction opposite to the direction of the arrow K1 in addition to the path Y1 in the radial direction with respect to the wood W rotating in the direction of the arrow K1 (FIG. 4). , A path Y3 curving in the direction of the arrow K1, a path Y4 curving in a bidirectional waveform, and the like. The change pattern of the carving pattern can be changed more variously.

In general, the decorative tool 10 is preferably rotated about 10 times or more faster than the rotation of the wood W in the no-load state. When the electric drill D is used, the wood W
It is preferable to use a drill D driven at 00 to 1500 rpm and having a rated no-load rotation speed of about 15000 rpm. It should be noted that the decoration tool 10 and the wood W may be changed in either one or both of them. Further, for example, by using a drill D connected to a driving source of the wood W through a flexible power transmission mechanism, it is possible to positively maintain the synchronous relationship between the decorative tool 10 and the wood W. Since it is possible, for example, by setting the synchronous relationship between the carved scratches W1, W1,. It is also possible to make it on the entire surface of the ground W.

Other Embodiments The decorative tool 10 may be formed in any shape as long as the cutting edge 12a formed in the processing portion 12 intermittently hits the decorative object. For example, the tip of a round bar is cut through a slope 12b (FIG. 5), the slope 12b is bisected in the longitudinal direction to provide a notch 12c along the axis C1, and a rake face 12d is formed at the corner of the tip. If the cutting edge 12a is formed by providing the same, the cutting edge 12a is sharp, so that it is possible to easily decorate a decoration target made of a hard material.

Alternatively, the tip portion of the round bar may be bent slightly to form an attachment portion 11 (FIG. 6), and a cutting tool 12e made of, for example, high-speed steel or cemented carbide may be attached to the tip portion to form the processed portion 12. Since the diameter of the rotating circumference C can be increased, the engraved scratch W
It is easy to increase the length of each of W1,..., And a new change can be realized in the engraving pattern when the decoration object has a large diameter.

The processing section 12 may be formed by a grinding wheel 12f (FIG. 7). A part of the circumference of the end of the grinding wheel 12f is a cutting edge 1
Acts as 2a. Since the grinding wheel 12f can easily apply engraving scratches W1, W1 ... even on hard and smooth base lacquer, it can be applied to decorative objects consisting of intermediate products coated with two or more base lacquer layers, for example. On the other hand, it is possible to apply a carved pattern by changing the color.

Further, two or more cutting edges 12a may be provided (eighth cutting edge).
At that time, all the cutting edges 12a, 12a ...
It is preferable to align them on a single rotation circumference C around the axis C1. For example, one end of the mounting portion 11 is
If the processing part 12 is formed by attaching the blades 12e, 12e to the respective tips, the cutting edge 12a when the rotation speed of the decoration tool 10 and the rotation speed of the decoration target are constant. In addition, the engraving pattern can be applied twice as finely to one piece, and the dynamic balance of the decorative tool 10 can be easily maintained.

In addition, this invention can be applied not only to lacquer ware and its wood W, but also to porcelain. In this case, for example, the dull cutting edge 12
What is necessary is just to attach the intermittent engraving pattern to the surface of the decoration object using the decoration tool 10 having a.

Effects of the Invention As described above, according to the present invention, a decorating tool having a discontinuous cutting edge is rotated on the rotating circumference, and the rotating circumference is brought into contact with the surface of the rotating decoration object. By moving along the path in the radial direction while making it, even an unskilled person can easily form a beautiful carved pattern on the decoration object including lacquer wood and intermediate products etc. Has an effect.

Furthermore, by changing the relative rotation ratio of the decoration object and the decoration tool, or changing the moving path of the decoration tool, it is practically possible to realize various carving patterns. There is also an excellent effect.
