Description

TECHNICAL FIELD

[0001] The application relates to a manufacturing method of a gold basket jadeite three-dimensional hollow ornament and hollow vessel, and belongs to the technical field of precious metal and cultural relic protection. BACKGROUND

[0002] The gold basket jadeite process is one of traditional Chinese precious metal fine decoration categories, and is a process of forming various precious metal patterns on the surface of a precious metal article or a precious metal ornament according to a pattern, decorating the traditional pattern or a unique totem, and then paving extremely small precious metal beads or precious metal ball beads and inlaying gemstones to form an ornament or a vessel. The gold basket jadeite product has the advantages of significantly improving the artistic value, cultural value and collection value of the ornament and the vessel. However, the traditional gold basket jadeite product has extremely great manufacturing difficulty and a long manufacturing period. Specifically, the combination welding of the precious metal wire and the precious metal bead on the surface of the three-dimensional article or the extremely small hollow ornament pit surface cannot use any adhesive, the formed pattern line and the combination welding of the precious metal bead must be completely consistent with the designed pattern, the welding interface cannot be shown, the three-dimensional modeling assembly and the full assembly welding cannot affect each other, and therefore, the high-temperature welding temperature control needs to be accurate, otherwise the precious metal wire and the precious metal bead cannot be positioned or appear to be fused, bonded and burned. Even if the welding is forced, the product is not firm or appears to be displaced and opened. The manufacturing difficulty is beyond imagination, the product yield is low, and especially when the precious metal wire and the extremely small precious metal bead are combined to form a micro-pattern with dense decoration and need to be welded on the three-dimensional assembly, the welding difficulty and precision increase geometrically, the manufacturing period is infinitely enlarged, and the satisfactory product effect and the precious metal cultural relic protection and restoration effect cannot be achieved. Therefore, a manufacturing method of the gold basket jadeite three-dimensional hollow ornament and the hollow vessel with high product yield and short period is urgently needed. SUMMARY

[0003] According to one aspect of the application, a manufacturing method of a gold basket jadeite three-dimensional hollow ornament and hollow vessel is provided to overcome the problems that the gold basket jadeite process vessel and ornament in the prior art are deformed, welded and fused at the decoration welding position, and the precious metal bead is easily separated from the welding position.

[0004] A manufacturing method of a gold basket jadeite three-dimensional hollow ornament and hollow vessel comprises the following steps.

[0005] (1) A bottom mold, metal wires and inlaid ornaments needed for manufacturing the hollow ornament are prepared according to a designed pattern decoration or a cultural relic prototype.

[0006] (2) The metal gold and silver wires are formed and attached on the bottom mold according to the pattern to form a three-dimensional hollow part.

[0007] (3) engraving positioning grooves on the three-dimensional hollow piece;

[0008] (4) dividing the welding area according to the overall contour shape of the three-dimensional hollow piece;

[0009] (5) according to the welding area, controlling the welding temperature in a decreasing manner to sequentially weld the already made inlaid jewelry into the corresponding positioning grooves in the order of the divided welding areas through the welding process;

[0010] (6) post-processing.

[0011] Preferably, the bottom tire is made through a precious metal forging or hammering process.

[0012] Preferably, the preparation process of the bottom tire includes:

[0013] First, melt the gold / silver raw material needed to prepare the bottom tire into a gold / silver liquid at a high temperature above 1000°C;

[0014] Then, pour the gold / silver liquid into a mold to prepare a block or strip-shaped gold / silver block;

[0015] Finally, make the bottom tire in the shape of the design pattern or the shape of the cultural relic prototype through a forging or hammering process.

[0016] Preferably, the process of the wire pattern is to form a gold / silver or other metal wire according to the design pattern and stick it on the bottom tire.

[0017] Preferably, the caliber of the positioning groove is 1 / 3 of the outer diameter of the inlaid jewelry to be welded.

[0018] Preferably, the welding temperature of a unit welding area is 5-10°C lower than the critical point temperature of the precious metal material to be welded in the area.

[0019] Preferably, the welding process is performed in the order of welding from high temperature to low temperature near the melting point value, from the whole to the subassembly to the whole assembly.

[0020] Preferably, the welding process of a single subassembly is as follows:

[0021] First, use weak soft fire to weld when borax Na2B4O7·10H2O and welding flux are on fire;

[0022] Then, gradually expand and contract the borax Na2B4O7·10H2O to the original point, and then perform overall overfire heating in the high-temperature area;

[0023] Finally, after the weldment gradually turns pink, focus the welding gun tip on the welding center point within 1-3 seconds and weld quickly with high fire in a circular manner to control the welding temperature and melt the flux at a uniform speed, finally completing the welding thoroughly.

[0024] The beneficial effects of this application include:

[0025] The present application carves positioning grooves on a three-dimensional hollow part according to the design pattern of a gold basket or a treasure ornament or the design position of the prototype of a cultural relic to position the precious metal gold and silver round beads or precious metal gold and silver steamed bun-shaped round beads to be welded, thereby avoiding displacement deviation of the precious metal gold and silver round beads or precious metal gold and silver steamed bun-shaped round beads due to their easy movement during welding, resulting in quality defects such as adhesion, melting and destruction, and falling off of precious metal round beads due to loose welding. In addition, during batch welding, the position deviation of one of the precious metal round beads may cause errors in the rest, resulting in a large amount of rework. By dividing the three-dimensional hollow part into areas and following the order of the divided welding areas, the welding temperature of each welding area is controlled to be 5°C to 10°C lower than the melting point of the critical melting point of the precious metal material, and the precious metal gold and silver beads or precious metal gold and silver steamed bun-shaped beads are welded in each welding area in sequence, thereby avoiding the situation where adjacent welding areas are melted, adhered, burned or fall off due to the same temperature, thereby providing a method for producing three-dimensional hollow gold basket and precious stone ornaments and hollow utensils with a high yield and a greatly shortened production cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 This is a schematic diagram of the process of manufacturing a three-dimensional hollow ornament and hollow vessel made of a gold basket and precious stones in this application. DETAILED DESCRIPTION

[0027] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0028] Implementation

[0029] First, prepare the raw materials needed to make the three-dimensional hollow gold basket and precious stone ornaments. These raw materials include the block or strip gold / silver material needed to prepare the base, the metal wire needed for the filigree pattern (in this embodiment, including but not limited to gold or silver wire), and the inlaid ornaments (in this embodiment, the inlaid ornaments include but are not limited to gold and silver wire, the required inlaid gemstones, and any one or more of the prepared tiny round beads or bun-shaped precious metal particles).

[0030] Secondly, make the base, filigree patterns and inlaid ornaments respectively;

[0031] The whole manufacturing process of the base is as follows: first, melt the gold / silver raw material needed for manufacturing the base into liquid at a high temperature of 1000℃ or above, then pour into a mold, and after solidification and cooling, a block or strip of gold / silver is obtained; second, forge or hammer the gold / silver into the shape of the ornament or vessel to be manufactured.

[0032] The manufacturing process of the inlaid pattern is as follows: first, prepare the metal wire needed for inlaying; second, according to the designed pattern, bend the gold / silver or other metal wire on the front surface of the base to form a pattern, and weld it on the base to form a three-dimensional hollow part with the same pattern as the designed pattern;

[0033] The manufacturing process of the inlaid ornament is as follows: manufacture the noble metal (in this embodiment, the noble metal includes but is not limited to gold and silver) into round particles with equal size and close to 1mm;

[0034] Then, engrave positioning grooves on the formed three-dimensional hollow part;

[0035] Finally, divide the welding area (group) according to the external contour of the formed three-dimensional hollow part, and weld the inlaid ornament on the corresponding positioning groove according to the sorting of the divided area. Different welding areas correspond to different welding temperatures, and the temperature difference between adjacent welding areas is at least 10℃.

[0036] Weld the inlaid ornament in each area in turn according to the order of the divided areas in a decreasing temperature manner;

[0037] The division standard of the welding area is mainly the distance between the welding position and the base;

[0038] The sorting of the welding area is the maximum distance between the welding position and the base as the first area, and then the distance between the welding position and the base decreases to the second area, the second area, etc.

[0039] During welding, the welding temperature of the first area is the highest, and then the welding temperature of each welding area is controlled in a decreasing temperature manner according to the sorting of the welding area, and the welding process of each welding area is completed in turn according to the order of the welding area, so that the inlaid ornament (such as inlaid gem, small round bead or dumpling-shaped noble metal particles) is finally welded in the corresponding positioning groove;

[0040] The welding temperature of each welding area is controlled to be lower than the critical point temperature of the melting point of the noble metal to be welded in the welding area or 5-10℃;

[0041] By welding the inlaid ornament in each region in a temperature decreasing manner according to the sequence of the welding regions, the temperature melting point of the welding region being operated and the adjacent last welding region is blocked from high-temperature heat absorption, so as to achieve the purpose of safe welding.

[0042] The welding process of the inlaid ornament on each positioning groove is as follows: when borax Na2B4O7·10H2O and welding flux are burned, weak soft fire is used first, and then the borax Na2B4O7·10H2O is gradually expanded and contracted to the original point, and then the whole area is heated by strong fire, and after the welding part is slightly pink, the welding center point is quickly focused and circled by strong fire for rapid welding, so as to control the temperature and uniform melting of the welding flux, and finally complete the welding.

[0043] Finally, post-processing is performed, and the post-processing includes filing and polishing.

[0044] It should be noted that the metal wire in the wire pattern process in the embodiment is usually a flat wire obtained by pressing a metal round wire with the same thickness.

[0045] In order to realize that the caliber of the positioning groove is 1 / 3 of the outer diameter of the inlaid ornament, the purpose is to facilitate positioning, avoid welding misplacement and the distortion of the wire pattern during welding, and too small caliber will cause the inlaid ornament to be not firmly welded and easy to fall off, and will not produce adhesion during welding.

[0046] When the positioning groove is chiseled, the chisel used cannot be a thin mouth chisel, and the thickness of the blunt mouth chisel edge cannot be greater than 1 / 3 of the diameter of the welded precious metal bead, so as to accurately chisel the positioning groove.

[0047] The present application performs physical chisel groove positioning processing on the welding of dense and small precious metal particles on the full solid hollow part, so that the small pattern bead arrangement is effectively positioned, not easy to shift, bond and fall off. The manufacturing method is simple, efficient, green and environmentally friendly, greatly reducing the difficulty and period of the reproduction of precious metal cultural relics.

[0048] The above is only a few embodiments of the present application, and does not limit the present application in any form. Although the preferred embodiments are disclosed above, the present application is not limited thereto, and any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, which are equivalent to equivalent embodiments, and all belong to the scope of the technical solution.
