Description

Technical Field

[0001] This invention relates to a method for preparing metal utensils, reliefs, or sculptures, and more particularly to a method for preparing utensils, reliefs, or sculptures using multi-metal composites, which is different from traditional hand-hammering, casting, and spinning methods. Background Technology

[0002] Metal utensils can be used as containers or displayed as handicrafts. Currently, metal utensils are generally made by hand hammering and machine spinning to form multi-layered structures, and then patterns are engraved to combine the colors of each layer with the engraved patterns to enhance their aesthetic appeal.

[0003] However, manual hammering usually involves hammering a single metal into shape first, then hammering another metal into shape, and finally combining them (copper-plated silver). This process is inefficient, and the two metals are not composite structures, resulting in a limited variety of styles. Machine spinning, on the other hand, can only composite metals layer by layer, meaning that the metals in the same layer are identical, making it impossible to composite multiple metals in the same layer. In addition, the thickness of each layer is affected by the mold, and if multiple thicknesses are required, batch molds need to be made, increasing costs. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, such as low efficiency of manual hammering forming, inability to composite metals, limited final styles, the requirement of using the same metal for each layer during machine spinning forming, which prevents the composite of multiple metals in a single layer, and high cost due to the need for batch molding of each layer, this invention provides a method for preparing utensils, reliefs or sculptures using multi-metal composites.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A method for preparing vessels, reliefs, or sculptures using multi-metal composites includes the following steps:

[0007] S1. Select a carrier: Choose either a naturally formed object or a manufactured object as a carrier. Natural carriers include trees, soil, sand, plaster, beans, rice, corn, bark, and stones. These carriers have naturally formed shapes and can produce finished products of various shapes. Manufactured objects include plaster for casting, clay for sculpting, and plaster for flat relief. These carriers can be made according to the design shape and are suitable for making finished products such as utensils. S2. Spraying: Use a spray gun to melt and spray metal wire onto the surface of the carrier. During spraying, different metal wires are used to spray the surface of the carrier in different areas and layers to form a multi-layer structure in each area. After spraying, peel off the multi-layer structure from the carrier to obtain the rough finished product.

[0008] S3, Grinding and Polishing: When making utensils and sculptures, the surface of the rough finished product is ground and polished. When making reliefs, grinding and polishing are not required.

[0009] S4, Engraving Patterns and Text: When making utensils and sculptures, patterns and text are engraved on the rough finished product after polishing. When engraving patterns and text, the layered structure of each area is combined with the depth and shape of the patterns and text, so that after engraving, the original colors of different metals are revealed in the patterns and text, resulting in colorful patterns and text.

[0010] S5, Coloring and Surface Protection: When making vessels and sculptures, the carved patterns and text are coated with varnish. After the uncarved areas oxidize and turn black, the entire rough surface is coated with varnish and left to dry completely to obtain the finished product. When making reliefs, the rough product formed in step S2 is directly colored and spray-painted for protection. The finished product image and cross-sectional view of the vessels are shown below. Figure 1 and Figure 2 This solution uses a spraying method to spray different metals onto a carrier in layers and sections using a spray gun to form a layered finished product. This not only solves the problem that the hammering process cannot achieve composite, but also the problem that the spinning process cannot achieve composite of multiple metals in a single layer. Furthermore, by spraying in sections and layers, combined with the final engraved patterns and text, multiple metal colors can be displayed on the finished vessel, greatly increasing the aesthetic appeal of the finished vessel.

[0011] Preferably, when the carrier is easily damaged by spraying, a thin aluminum layer is sprayed on the surface of the carrier as a base layer before spraying. When the carrier is not easily damaged by spraying, any metal layer is sprayed on the surface of the carrier as a base layer. Then, a layer of 191 resin is brushed on the base layer and 60-mesh fine sand is sprinkled on its surface. After drying, the rough product is divided into K layers. The first layer is divided into N regions, and the Kth layer is divided into P regions, where K is a positive integer greater than 1, and N and P are positive integers greater than 0. The preset metal is sprayed on different layers and different regions to obtain the desired rough product. After each layer is sprayed, the sprayed metal layer needs to be cooled to below 40 degrees Celsius. In addition, the masking method is used to protect the areas that do not need to be sprayed during spraying. When the finished product is used as a decoration, the aluminum layer, resin and fine sand are reserved for decoration. When the finished product is used as a food container, the aluminum layer, resin and fine sand are polished off. Because the metal will be sprayed and damage the plaster and other carriers during spraying, it is necessary to spray small aluminum particles at the bottom layer. Since the bottom layer is too thick during spraying, it will cause cracks. Therefore, the layer should just cover the carrier. After spraying, a layer of 191 resin is coated on the surface and fine sand is sprinkled as a support layer. Then, according to the design, the metal is sprayed in layers and sections. After molding, it is peeled off from the carrier to obtain a complete rough product.

[0012] Specifically, in step S1, when using a manufactured object as a carrier, a carrier is first made from one of the following materials: plaster, clay, or sand, according to the designed shape. The carrier is then sculpted and refined to obtain a shaped carrier, and finally sprayed with paint. The inner core of the plastic material has high-temperature resistance and can be easily removed later. In addition, due to its good plasticity, it can be designed into different shapes and the shapes can be reflected in the final product.

[0013] When using plaster, the plaster powder and water are mixed in a mass ratio of 100:38-41 and poured into a silicone mold to solidify, forming a shaped inset. Alternatively, the malleable material is poured into a container to solidify, forming a rough blank without a shape, which is then refined into a shaped inset. The container can be a silicone mold without a shape, a sand mold, an openable container, a container made of clay, or a removable container. When using inset spraying, the inset is first fixed on a turntable, and then the metal wire is melted and sprayed onto the surface of the inset using a spray gun.

[0014] Preferably, the metal wire is a combination of various materials including copper, brass, cupronickel, aluminum, zinc, lead, carbon steel, stainless steel, bauxite, and alumina. Depending on the design requirements, different areas are sprayed with different techniques, and then combined with the final engraving depth of the pattern and text to obtain a variety of colorful patterns and text, where the colors are either the original color of the metal or the color of the metal after oxidation.

[0015] Specifically, in step S1, the spray gun has three connectors. Two of these connectors are connected to an acetylene supply pipe and an oxygen supply pipe, respectively. Acetylene and oxygen are sprayed from the nozzle and burn at the nozzle. A metal wire is slidably mounted on the spray gun, with one end extending to the nozzle and the other end located at another connector connected to an air supply pipe. The air supply pipe propels the metal wire forward by spraying air, ensuring that the end of the metal wire is always in the combustion position at the nozzle. Furthermore, the pressure of the acetylene and oxygen is adjusted according to the melting point of different metals. Preferably, a sliding cavity is provided on the spray gun, and the third connector is connected to one end of the sliding cavity, with the metal wire disposed within the sliding cavity.

[0016] Specifically, in step S3, the grinding and polishing includes coarse polishing and fine polishing. Coarse polishing is performed using 180-600 grit sandpaper of existing specifications, and fine polishing is performed once with a coarse scouring pad and once with a fine scouring pad.

[0017] Compared with the prior art, the advantages of this invention are as follows: This solution uses a spraying method to spray different metals onto the inner blank in layers and sections through a spray gun to form a layered finished product. This not only solves the problem that the hammering process cannot achieve composite, but also solves the problem that the spinning process cannot achieve composite of multiple metals in a single layer. Moreover, by spraying in sections and layers, combined with the final engraved patterns and text, colorful and diverse patterns and texts can be displayed on the finished product, which greatly increases the aesthetics of the finished product.

[0033] Example 2

[0034] As shown in Table 1, a comparison is made between the traditional hand-hammering process, the machine spinning process, and the process of this application in terms of metal material, metal thickness, number of metal layers, shape design, and the difficulty of producing the same shape when making vessels. As can be seen from the table, hand-hammering can only achieve effects such as copper-plated silver, and the various metals are embedded in the structure without being composite, and the efficiency is low. Although machine spinning is efficient, it has limited metal selection due to hardness and other factors. In addition, the shape selection is also limited, and it requires batch mold making, which is costly. The process of this application has a wide selection of metals, moderate efficiency, and a wide variety of shapes, and can achieve composite of various metal layers and sections.

[0035] As shown in Table 2, natural formations are used as carriers. In the actual production process, natural formations are divided into three-dimensional moldless and two-dimensional moldless. The finished product is formed based on the shape of the natural formation, with a unique shape. This type of carrier is suitable for making reliefs.

[0036] As shown in Table 3, which illustrates the use of man-made objects as carriers, the carriers are divided into three-dimensional indentations and two-dimensional reliefs in the actual production process. The finished products are formed based on the shape of the natural objects, resulting in a variety of shapes. This type of carrier is suitable for making reliefs, sculptures and vessels.

[0037] As shown in Table 4, a comparison is made between traditional hand-hammering, machine spinning, and the process described in this application when creating sculptures and reliefs, considering factors such as metal material, metal thickness, number of metal layers, design, and the difficulty of producing the same design. The table shows that hand-hammering can only achieve effects such as copper-plated silver, where multiple metals are inlaid rather than composite, and it is inefficient. Machine spinning, while efficient, limits metal selection due to hardness and other factors, and also limits design options, requiring batch molding and resulting in high costs. The process described in this application allows for a wider selection of metals, moderate efficiency, and a greater variety of designs, enabling the composite layering and partitioning of various metals.
