Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a nameplate with embossed characters masked on the surface of a metal substrate, an embossed dial for displaying in a frame, etc.
Family crest 1 clock face, Western tableware 1st place tile.

This relates to the manufacturing method of decorative items such as business card boards, crow buttons and brooches, and metal arts and crafts such as aluminum wheels for cars and gates.

[Problems to be solved by conventional technology and invention]

The conventional manufacturing method for metal arts and crafts such as nameplates is to simply mask the characters you want to emboss on the surface of a metal substrate such as copper or brass with anticorrosive ink, and then immerse the metal substrate in an eroding liquid for a predetermined period of time to create a metal substrate. This method involved embossing the letters on the surface of the paper, and then painting the surface other than the letters black with blackening liquid as a finishing touch.

Therefore, conventional metal arts and crafts such as nameplates were simply flat surfaces with letters embossed on them.

The present invention provides a method for manufacturing metal arts and crafts such as nameplates in which a background pattern of letters can be easily formed using this conventional etching process.

[Means to solve the problem]

The present invention will be described below with reference numerals used in the drawings for easy comparison with the drawings showing an example of implementation.

Mask the characters 2 that you want to be embossed on 1° of the surface of a metal substrate 1 such as copper or brass with anticorrosion ink, and then print the metal substrate 1.
In the manufacturing method of metal arts and crafts a, such as nameplates, in which letters 2 are embossed on 1° of the surface of a metal substrate 1 by immersing it in an eroding liquid 3 for a predetermined period of time, the letters 2 to be embossed are masked with anticorrosive ink. The surface 1° of the metal substrate 1 is facing downward, and the surface 1° of the metal substrate 1 is 3° the surface of the eroding liquid 3.
Or fix it near the liquid surface and connect the metal substrate I and the eroding liquid 3.
Surfaces other than letters 2 due to bubbles 4 produced by a chemical reaction with! This invention relates to a method for manufacturing metal arts and crafts such as nameplates in which a concave-convex pattern 5 is formed on the surface.

In addition, the characters 2 to be embossed on the surface 1° of a metal substrate 1 such as copper or brass are masked with anti-corrosion ink, and the metal substrate I is immersed in the eroding liquid 3 for a predetermined period of time, so that the characters 2 are embossed on the surface 1° of the metal substrate 1. In the manufacturing method of metal arts and crafts a such as nameplates with the letters 2 embossed, masking is applied to form a back pattern 6 on 1° of the surface other than the letters of the metal substrate I on which the letters 2 are embossed, and this metal substrate is then removed again. 1 in an eroding liquid for a predetermined period of time to remove the surface other than the letters on the metal substrate 1! ” character 2
The present invention relates to a method for manufacturing a metal arts and crafts such as a nameplate, which is characterized by forming a back pattern 6.

[Effect]

Regarding claim 1, the surface 1° of the metal substrate 1 on which the embossed or characters 2 are masked with anticorrosive ink is facing downward, and the surface 1° of the metal substrate 1 is at or near the liquid level of the erosive liquid 3. Fixed to.

Since the bubbles 4 generated by the chemical reaction between the metal substrate 1 and the eroding liquid 3 remain on the surface 1° of the metal substrate 1, the erosion progresses.
An uneven pattern 6 is formed on the surface 1'' other than the characters 2.

Regarding claim 2, masking is applied to form a back pattern 6 on the surface 1'' of the metal substrate 1 other than the letters 2 on which the letters are embossed by immersion in the eroding liquid 3 for a predetermined period of time, and the metal substrate 1 is eroded again for a predetermined period of time. Immerse in liquid 3.

The eroded surface other than letter 2 l°, the back pattern 6, and the unevenness formed in the order of letter 2, and the surface other than letter 2 is embossed! ” A back pattern 6 is formed.

〔Example〕

This embodiment, in which a nameplate is manufactured using a copper substrate 1 as the metal substrate 1, will be explained in detail by dividing each step.

(i) First, the implementation according to claim 1 will be described in detail.

■Pre-treatment process: Polish the entire surface of the copper substrate l with Scotchbrite, then apply baking soda and gently polish with a bristle brush to degrease and remove oil to avoid repelling chemicals.

■Masking process copper substrate! The surface of! Draw the desired character 2 (character 2 "Ishikawa" in the drawing) evenly on ° with anti-corrosion printing ink,
Furthermore, the side and back surfaces of the copper substrate 1 are evenly masked with anti-corrosion printing ink, except for the surface violets other than the characters on the copper substrate 1.

■Etching process This is the main process of the present invention, and as shown in Fig. 5, the surface 1'' on which the characters 2 are masked is facing downward and near the surface of the etching liquid 3 using ferric chloride. Etching is performed by fixing the film in a liquid immersion state for several hours.

The fixing means may be any means, but the drawing shows the copper substrate 1.
The figure shows a case in which a wire 8 with a suction cup 7 is attached to the back surface of the device by hanging and fixing it.

As shown in FIG. 5, the bubbles 4 generated by the chemical reaction between the surface 1° of the copper substrate 1 and the eroding liquid 3 continue to erode while remaining on the surface 1°. Second
The surface other than the embossed character 2 as shown in the figure! ”
An uneven pattern 5 is formed on the surface.

In order to form the concavo-convex pattern 5 well, it is preferable to use a large container 9 that contains the tarapuri and the eroding liquid 3 and allowing good circulation of the eroding liquid 3.

■Finishing process The etched copper substrate 1 is washed with water, and 1° of the surface of the copper substrate 1 is blackened with a blackening solution. Then, remove the anticorrosive printing ink with printing thinner or thinner, polish with Scotchbrite, degrease with baking soda, and polish the embossed character 2 with clear lacquer.

(ii) Next, the present implementation according to claim 2 will be described in detail.

Copper substrate 1 after completing the pretreatment process (■) and masking process (■)
As shown in FIG. 6, etching is performed for several hours in the same manner as in the conventional etching process.

At this point, take out the copper substrate 1 on which the desired amount of letters 2 have not yet been completely embossed, and use a fine pattern sheet used for dyeing kimono to print a back pattern 6 on the surface 1° with anticorrosion printing ink. It is masked in order to form the etching, and then immersed in the eroding liquid 3 for several hours again for etching, and then taken out.

As shown in Fig. 3 and Fig. 4, the eroded surface has irregularities formed in the order of 1" back pattern 6 (wavy small pattern in the drawing) 1 character 2, and back pattern 6 is formed on the surface 1" other than character 2. .

This back pattern 6 is not limited to a small pattern, but may be any pattern.

Further, in the present invention, the characters 2 may be etched in reverse so that the surface other than the characters is recessed by 1°.

In addition, by combining the embodiments according to claims 1 and 2,
A back pattern 6 such as a small pattern may be formed while forming an uneven pattern 5 of bubbles 4.

〔Effect of the invention〕

According to the present invention, uneven patterns and back patterns made of bubbles can be extremely easily formed on surfaces other than embossed characters, making it possible to mass produce metal arts and crafts such as patterned nameplates and embossed dials that can be displayed in frames at low cost. This is the manufacturing method for metal arts and crafts such as nameplates.
