[0002] The gold-wrapped silver teapot is a traditional handicraft. Its production process combines the characteristics of gold and silver. It uses silver as the base and gold as the outer layer, forming a teapot with unique artistic and practical value.

[0003] In the prior art, the gold-clad silver teapot is usually made through the following steps: 1. Silver blank production, using pure silver material to forge or cast the basic shape of the teapot according to the design drawings; 2. Gold sheet preparation, selecting gold sheets of appropriate thickness; 3. Preheating and bonding: heating the silver blank to a certain temperature, and then quickly and evenly covering the pre-prepared gold sheet on the silver blank, using high temperature to make the two tightly bonded; 4. Pressing and forming, further strengthening the bonding force between the gold layer and the silver blank through mechanical pressing or other methods, and the product shape can also be adjusted in this process; 5. Pot processing, matching the spout, upper handle, and lid to obtain the finished gold-clad silver teapot. However, this production method also has some shortcomings. For example, in the above processing method, bubbles are easily generated in the gold and silver interlayer, and the pot body is prone to bulging during long-term use; and the gold skin is easily damaged, and the silver base is exposed to the white, resulting in a decrease in aesthetics.

[0004] Therefore, a molding method of a gold-clad silver pot in which bubbles and whitening are not easily generated in the gold-silver interlayer and a gold-clad silver pot need to be designed. Summary of the invention

[0028] Please refer to Figure 1 The embodiment of the present invention provides a method for forming a gold-coated silver pot, which is used to make a gold-coated silver pot. The method for forming a gold-coated silver pot comprises the following steps:

[0029] S110, sheet pressing, selecting silver sheets and gold sheets of preset thickness, and pressing, compounding, heating, and flowing water to form a gold-clad silver composite sheet. Optionally, the silver sheets and gold sheets of preset thickness are pressed together by a press device, and the outer gold layer is heated and flowing water to form a continuous gold-clad silver composite sheet without gaps.

[0030] S120, cutting the gold-clad silver composite sheet into a disc of a required size. Optionally, according to the target silver pot style, the specific diameter of the required disc-shaped gold-clad silver composite sheet is determined based on the corresponding design drawing and sufficient processing allowance, and the disc is cut from the gold-clad silver composite sheet according to the specified size by a cutting tool, while ensuring that the edges are neat and burr-free.

[0031] S130, spinning and shaping, fixing the disc-shaped gold-coated silver composite sheet on the mold of the spinning molding device, and using the pressure rod of the spinning molding device to gradually apply pressure from the bottom to the mouth to shape the pot body. Specifically, the spinning molding device is a prior art, so it will not be expanded here. The invention point of the present application is to use the pressure rod of the spinning molding device to gradually apply pressure from the bottom to the mouth to shape the pot body. The shape of the mold corresponds to the shape of the inner cavity of the pot body. The process of the pressure rod gradually applying pressure from the bottom to the mouth needs to maintain continuity and uniformity, so that the gold sheet and the silver sheet can be tightly combined, and at the same time any air that may exist can be discharged to prevent the generation of bubbles.

[0032] S140, closing the mouth, closing the upper mouth of the pot body to form a smooth pot mouth. Optionally, after the upper mouth of the pot body is closed to form the pot mouth, the pot mouth can be finely polished by a grinding wheel or a polishing machine to remove excess metal and ensure that the edge is flat and smooth.

[0033] S150, processing the finished pot, matching the spout, the handle and the lid to obtain a finished gold-clad silver pot. Specifically, in addition to the pot body, the spout, the handle and the lid can be independently processed to be a spout, handle and lid of the pot covered with gold and silver, and then the spout and handle of the pot covered with gold and silver are welded to the pot body, and the lid is placed on the pot mouth to obtain a finished gold-clad silver pot.

[0034] The forming method of the gold-coated silver pot is to fix a disc-shaped gold-coated silver composite plate on the mold of a spin forming device, and use a pressure rod of the spin forming device to gradually apply pressure from the bottom to the mouth to shape the pot body; in this way, the molding speed of the pot body is fast, and the cooperation of the pressure rod and the mold of the spin forming device can provide a larger pressure to make the gold sheet and the silver sheet fit better, and can effectively discharge the residual gas in the gold and silver interlayer to avoid the formation of bubbles; because there are no bubbles in the gold and silver interlayer, during long-term use, the pot body will not bulge, the gold skin will not be damaged, and the silver base will not be exposed.

[0035] In order to make the gold-coated silver pot have high importability and facilitate processing, optionally, in the present embodiment, in the step S110 of the forming method of the gold-coated silver pot, the thickness of the silver sheet is ≥1.5mm, and the thickness of the gold sheet is ≥0.5mm. For example, optionally, the thickness of the silver sheet is 1.5mm, and the thickness of the gold sheet is 0.5mm; the thickness of the silver sheet is 1.6mm, and the thickness of the gold sheet is 0.6mm; the thickness of the silver sheet is 1.8mm, and the thickness of the gold sheet is 0.5mm. As long as the thickness of the silver sheet is ≥1.5mm, the thickness of the gold sheet is ≥0.5mm, and it meets the size of the pot body, no specific restrictions are made here.

[0036] In order to improve the cutting accuracy in step S120, optionally, in this embodiment, in step S120 of the gold-clad silver pot forming method, a CNC punching machine or a laser cutting machine can be used to cut the gold-clad silver composite plate. In this way, the cutting accuracy and work efficiency of the gold-clad silver composite plate can be improved.

[0037] In order to better control the pressure rod to shape the gold-clad silver composite plate, so that the gold sheet and the silver sheet fit better and discharge the residual gas in the gold-silver interlayer, optionally, in the step S130 of the forming method of the gold-clad silver pot in this embodiment, a numerical control system is used to accurately control the rotation speed, movement trajectory and pressing force of the pressure rod of the spinning forming device. Specifically, the use of a numerical control system to control the precise control of the pressure rod of the spinning forming device belongs to the prior art, so it will not be elaborated here.

[0038] In order to make the mouth of the gold-covered silver pot more beautiful and avoid an obvious gold-silver separation layer, optionally, in the present embodiment, in step S140 of the forming method of the gold-covered silver pot, the gold sheet can be extended and wrapped into the pot and at least cover a portion of the silver inner wall of the pot mouth to form a smooth and integrated pot mouth.

[0039] In order to achieve the spout of the gold-clad silver pot, optionally, in this embodiment, the steps of the spout are as follows: first, a hole is punched on one side of the pot body to form a water outlet, then the silver tube of the gold-clad silver pot spout is welded from the inside to the outside to the silver inner wall of the pot body at the water outlet; then the gold outer skin of the gold-clad silver pot spout is connected to the gold outer wall of the pot body at the water outlet by heating and running water. In this way, the consistency of the overall appearance is achieved.

[0040] In order to realize the upper handle of the gold-clad silver kettle, optionally, in this embodiment, in step S150, a gold-clad silver kettle handle is welded on the side of the kettle body opposite to the kettle spout. Specifically, a blind hole can be drilled on the side of the kettle body opposite to the kettle spout, and the blind hole is connected to the inner wall of the silver sheet, and then the silver core of the prepared gold-clad silver kettle handle is welded to the inner wall of the silver sheet of the kettle body, and then the gold outer skin of the gold-clad silver kettle handle is connected to the gold outer wall of the kettle body at the water outlet through heating and water flow. In this way, the consistency of the overall appearance is achieved.

[0041] Optionally, in this embodiment, in step S150, a gold-plated silver pot lid whose size matches the pot mouth is made by a spinning forming device. Of course, in other embodiments, the lid can also be made by hand, which is not specifically limited here.

[0042] In order to make the produced gold-coated silver pot more beautiful and ensure the quality of each gold-coated silver pot, optionally, in this embodiment, after step S150, it also includes: step S160, carving and inspection, carving patterns on the surface of the pot body, pot lid and pot handle of the finished gold-coated silver pot, and testing its sealing through water injection and boiling water test.

[0043] Another aspect of the embodiment of the present invention provides a gold-covered silver kettle, which is made by the forming method of the gold-covered silver kettle as described above. Since the gold-covered silver kettle has all the steps and process relationships of the forming method of the gold-covered silver kettle, it has all the advantages of the forming method of the gold-covered silver kettle, which will not be described in detail here.
