  In the present invention, when manufacturing precious metal, metal, or resin frames of various and various shapes of jewels and shell processed products, the shape of the jewel is read in detail from 360 degrees and read using a three-dimensional scanner. After importing the gem data into the 3D drawing design software, the best shape to fix the gem is designed with the 3D drawing design software, fine adjustments are made, and the designed shape is waxed with the stereolithography machine. It is related to manufacturing a frame of the best size and shape for fixing a gemstone by pouring a noble metal material or metal into a mold after manufacturing a mold with wax or resin.

  When manufacturing precious metals and metal frames to fix various and various shapes of jewelry, so far, rolled plates and wires are manually wrapped around the jewelry, or the solid material called wax is manually inserted into the jewelry. We produce gemstones and metal frames by shaving, making jewels directly and making original molds, and tracing jewels on the surface of materials.

  However, precious metals and metal frames made by the above-described manual manufacturing methods are separated from the fine surface lines of gemstones and are deformed, and there are many problems.

  Furthermore, since the above-described manufacturing method goes through a complete manual process, it takes a lot of time to reach a finished product.

  In the current jewelery market, buyers prefer the uniqueness of products using jewels, so there is a tendency to select various and various shapes of jewels, and there is an urgent need to solve the problems described above. ing.

  Patent Publication 2009-183553

  The present invention solves the above-mentioned problems, and can manufacture precious metals and metal frames that can be matched to a wide variety of gemstones without any difference in size. A method for producing a precious metal frame for jewelry is provided.

  In order to solve the above problems, the appearance of various gemstones is analyzed in detail from a 360-degree direction with a 3D scanner, and irregularities and dimensions are converted into digital data, which are imported into 3D drawing software. After creating the original mold by wax cutting, resin lamination type 3D printing machine, or resin lamination type stereolithography, create a frame with 3D drawing software with somewhat larger dimensions against the surface irregularities of The precious metal and metal frame are completed through the lost wax casting process.

  In the present invention, there is no jewelry frame that cannot be manufactured.

  In the present invention, it is possible to create a frame that fits even with a jewel having a complicated shape.

  In this invention, since the frame can be created in a short time, the manufacturing cost can be greatly reduced as compared with the conventional manual process product.

  In the present invention, since any shape of jewelry frame can be created, it can be manufactured as a pendant, earring, ring or the like.

  According to the present invention, jewelry frames of any shape can be created freely and easily, so that it is possible to easily meet various consumer demands and at the same time increase consumer satisfaction. In addition, since it can be produced at low cost, it has become possible to provide inexpensive products.

  This invention precisely measures the size and irregularities of a wide variety of gemstones with a 3D scanner, imports the data into 3D drawing design software, and produces data with a frame that is somewhat larger than the gemstone, After creating the original mold with a wax cutting machine, resin lamination type 3D printing machine, or resin lamination type stereolithography equipment, a decorative frame as a precious metal or metal ornament or figurine is produced by the lost wax casting method It is.

  First, measure the dimensions and irregularities of various gemstones that you want to create a frame of precious metal or metal, so that they will fit in an error of about 50 microns with a 3D scanner.

  Next, the gem data measured by the three-dimensional scanner is taken into the three-dimensional drawing design software and recognized as one individual.

  Then, on the 3D drawing design software, 3D drawing design software generates data of a precious metal or a shaped object that can eventually become a metal frame around the entire gem data captured by the 3D drawing creation software.

  In order to produce a noble metal or a metal frame with 3D drawing software, it is necessary to individually consider the shrinkage that occurs between the melting and solidification of the noble metal or metal that can be the final product.

  For that purpose, it is necessary to create a large distance so that the distance from the surface of the gem data is uniform within a range of about 0.01 mm to 0.8 mm at all points.

  In addition, the surface that is in contact with the gem data surface of the 3D drawing of the frame created from the data obtained by measuring various gems with a 3D scanner faithfully reproduces the irregularities of the gem, so depending on the shape of the gem There are many irregularities, and if it is made as it is, it may look inferior as an ornament.

Therefore, the surface that is not in contact with the surface of the jewel data, that is, the outer surface that can be seen as the appearance, needs to be smooth from the viewpoint of appearance and feeling of use.

  The surface that does not touch the surface of the jewel data, that is, the outer surface that can be seen as the appearance, is a smooth curved surface, sphere, or plane on the 3D drawing software. is there.

  Various kinds of jewelry frames created with 3D drawing software can be crafted to make holes or the like to reduce weight, or you can attach as many small jewelry frames as needed to attach diamonds etc. .

  The various and various jewelry frames created by the 3D drawing creation software are created in exactly the same shape by a wax cutting machine, a resin lamination type 3D printing machine, or a resin lamination type stereolithography apparatus, and used as a prototype.

  The original frame of the frame made from various kinds of jewels created by wax cutting machine, resin lamination type 3D printing machine, or resin lamination type stereolithography equipment is converted into precious metal or metal frame by lost wax casting method. It will be.

  Various and various shapes of precious metals and metal frames produced by the lost wax casting method are finished through polishing and plating processes.

  In addition, the prototype made from the above-described resin laminate type three-dimensional printing machine can be used as it is, and subjected to resin plating or the like to be used as an ornament or an ornament.

  Also, if you want to use it as a pendant or necklace, you can do it by adding parts and fasteners, and if you want to make a ring, just attach it to the ring and you can use it as your favorite decoration It is.

[Example 1]
In the present invention, since it is possible to select a frame for which a frame is to be created from a wide variety of jewels, a jewel block called a peridot having a size of about 10 mm in length, 5 mm in width, and about 4 mm in thickness is selected.

  The selected massive gemstone peridot was placed in the measurement part of the 3D scanner, and the measurement was started after setting the 3D scanner so that measurement could be performed with an error of about 50 microns.

  Since the 3D scanner cannot measure from all directions at once, the gemstone peridot was set several times and measured several times.

  The data of the massive gemstone peridot of the 3D scanner after the measurement was combined as a single data and imported into 3D drawing software.

  The block-shaped gem peridot data imported to the 3D drawing software can be reproduced in detail and irregularities. Based on this gem data, the shape of the frame can be used as an ornament in the 3D drawing software. Made.

  Since the metal used for the decoration contracts as it solidifies through the melting process, the surface of the frame that touches the gemstone was designed to be 0.8 mm larger from the gem data.

  Also, if the surface that can be the external appearance is designed like the surface that touches the gemstone, irregularities on the surface of the gemstone and even scratches may be reflected, so it does not touch the gemstone. The outer surface was made with 3D drawing design software so as to be a smooth surface or a flat surface.

  In addition, the frame produced above was drilled with several holes so that it could be reduced in weight, and was crafted so that a 1 mm diamond could be attached to improve the appearance.

  The data of the frame used for the massive gemstone peridot produced by the 3D drawing production software is used as a computer extension that can be read by the device in order to create the original mold by the resin lamination type stereolithography device. Created the type that becomes.

  The original mold made of the resin produced by the resin-stacked stereolithography device is exactly the same as the 3D drawing production software. When a massive gemstone peridot is inserted in the trial, it is just right with some margin It was a size.

  Gypsum in which the original mold made of resin is dissolved in water in order to produce a noble metal frame by the lost wax casting method based on the original mold made of resin produced by the resin laminated stereolithography equipment A gypsum mold was created.

  Since the gypsum mold is fired at a high temperature, the resin melts and the original mold portion is hollow.

  18 gold melted at about 1000 ° C. was poured into the gypsum space, waited for the metal to solidify, and the contents were removed from the gypsum.

  I put a lump of gem peridot into the frame shape made of 18K gold taken out of plaster and polished it, and there was almost no gap between the gems due to shrinkage of the bullion. fixed.

  A small diamond is fixed to the above frame, a fastener is added so that it can be used as a pendant, and a massive gemstone peridot is inserted and fixed with a transparent adhesive, creating an unprecedented ornament that looks great. It was.

  In the manufacturing method of creating a precious metal or metal frame on a wide variety of precious stones according to the present invention, a precious metal or metal frame can be precisely and inexpensively easily attached to any shape of precious metal. In addition to the addition of elements that can be used as ornaments to gems that have been impossible to produce frames due to their complicated shape, they were expensive because they could only be handled by handmade items. Since the frame can be provided at a low price, the utility value of jewels can be greatly expanded, and the jewelry and ornaments market can be activated.
