Description

Technical Field

[0001] This invention relates to the field of jewelry and craft processing technology, and in particular to a method for making a phoenix ornament based on hammering and chiseling. Background Technology

[0002] As an auspicious mythical creature in traditional Chinese culture, the phoenix symbolizes wealth, good fortune, and rebirth. With people's increasing emphasis on traditional culture and their growing awareness of collecting, ancient gold artifacts are becoming increasingly popular in the market due to their unique handcrafted texture and cultural connotations.

[0003] Currently, most precious metal phoenix ornaments on the market are made using two main processes: lost-wax casting and machine stamping. Lost-wax casting involves creating a wax model, wrapping it in plaster, dewaxing at high temperatures, and pouring molten metal to form the product. It boasts high production efficiency and mass production capabilities. However, lost-wax casting produces smooth surfaces lacking the texture of hand-forged metal, resulting in a dull metallic feel and a lack of the layers and textures characteristic of traditional handcrafting. Each piece is identical, lacking uniqueness and collectible value. Furthermore, the casting process is prone to defects such as sand holes and air pockets, affecting product quality. Machine stamping, on the other hand, uses molds to press metal sheets onto a stamping press, resulting in extremely high production efficiency and low cost. However, machine-stamped products have limited depth of detail, lack three-dimensionality, and all products are identical, lacking the warmth and uniqueness of handcrafted pieces. Machine stamping also generates significant residual stress within the metal, making the finished product prone to warping and deformation after long-term display. Summary of the Invention

[0004] The purpose of this invention is to provide a method for making phoenix ornaments based on hammering and chiseling, thereby solving the technical problems existing in the prior art.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A method for manufacturing a phoenix ornament based on hammering and chiseling includes the following steps: S1: Blank pretreatment: The precious metal sheet is subjected to low-temperature annealing, with the temperature controlled within the range of 80-120℃ and held at a constant temperature for 25-35 minutes to eliminate residual internal stress from the rolling process; S2: Initial blank grading and cold forging shaping: The annealed blank is forged and shaped using a three-stage layered cold forging hammering process, including a rough hammer leveling stage, a medium hammer curved surface initiation stage, and a... S3: Segmented Blanking and Shaping Stage: According to the segmented structure design of the phoenix ornament, the forged blank is segmented and cut into five independent component blanks: phoenix head blank, chest and abdomen main body blank, double-layer phoenix wing blank, multi-layer phoenix tail blank, and claw and foot blank; S4: Three-Sequence Layered Differentiated Chasing: Using four types of chisels—flat chisel, line chisel, dot chisel, and curved feather chisel—the pattern processing of each component blank is carried out in three chiseling processes, including shallow chiseling to outline the contours of the sections. The process includes: line engraving, raised relief carving, and deep engraving of feather-like grooves; S5: Double-layer hollow phoenix wing composite: After aligning the two phoenix wing blanks, the edges are sealed using a manual hammering process, leaving an internal cavity before sealing pre-treatment to form a double-layer hollow phoenix wing component; S6: Forced-air brazing assembly: Using a manual forced-air brazing device and solder, the various components are welded in sections according to the welding sequence of main body first, then accessories, and from thick to thin. Assemble the whole piece; S7: Traditional hand polishing: Use an agate knife to manually polish each part, and then wash with wood ash water to fix the color and brighten it, preserving the original hand-hammered texture; Among them, in step S4, the wing feathers are engraved with a diagonal staggered arrangement, and the engraving row spacing is controlled at 0.4-0.6mm; the phoenix tail is engraved with long and short feathers in a layered staggered arrangement; the chest and abdomen are engraved with round down feathers, and the diameter of the engraving point is controlled at 0.25-0.35mm.

[0007] Furthermore, the low-temperature annealing treatment in step S1 adopts the ancient method of simmering in fire, in which the precious metal plate is buried in heated fine sand for uniform heating, and the sand temperature is controlled at 80-120℃.

[0008] Furthermore, in step S2, the frequency of hammer blows per unit area during the coarse hammer leveling stage is 145-200 times / day. During the initial arc stage of the middle hammer, the height of the main arc surface is controlled at 0.3-0.6cm. During the fine hammer base shaping stage, light hammers are used to repeatedly forge and form the basic texture.

[0009] Furthermore, the arc-shaped feather chisel in step S4 is an arc-shaped chisel with a circular arc blade and a radius of 2-5mm, used to engrave three-dimensional feather textures on the arc surface of the phoenix wings.

[0010] Furthermore, in step S5, the cavity thickness of the double-layered phoenix wings is controlled between 0.8 and 1.2 mm, and the edges are sealed by point-by-point hammering, with the weld width not exceeding 0.3 mm.

[0011] Furthermore, the welding sequence in step S6 is as follows: first, weld the phoenix head and the main body of the chest and abdomen to form the main structure, then weld the claws, feet, crown, and double-layered hollow phoenix wings in sequence, and finally weld the multi-layered phoenix tail components.

[0012] Furthermore, in step S7, the pressure of the agate knife during polishing is controlled at 5-15N, and the agate is repeatedly polished in the same direction until the surface presents a warm and matte texture; the wood ash water washing involves mixing 300-500 mesh wood ash with clean water in a ratio of 1:8-1:12 and then wiping the surface of the workpiece.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (i) The three-stage layered engraving process of this invention processes the pattern from shallow to deep, giving it a rich sense of layering and three-dimensionality. Different engraving techniques and pattern designs are used in different areas to simulate the feather characteristics of a real phoenix, thereby improving the artistic and ornamental value of the product.

[0015] (ii) The entire process of this invention is hand-forged and engraved, retaining the natural hammered texture throughout, which fundamentally distinguishes it from mass-produced products made by mold casting. The ancient craftsmanship is highly recognizable, and each piece has uniqueness and high collection value.

[0016] (iii) This invention reduces the residual stress inside the gold workpiece through low-temperature annealing and graded frequency-controlled hammering process, making it less prone to warping and deformation under long-term storage and temperature change environment, and significantly improving the product's stability and durability.

[0017] (iv) The five-part structure design of this invention, combined with the segmented brazing process, allows each component to be finely processed separately before assembly, improving processing accuracy and decorative quality; at the same time, the split structure facilitates maintenance and replacement, thus improving the product's service life. Attached Figure Description

[0018] Figure 1 This is a flowchart of a method for making a phoenix ornament based on hammering and chiseling, as disclosed in this invention. Detailed Implementation

[0019] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Example 1:

[0021] like Figure 1 As shown, this embodiment provides a method for making a phoenix ornament based on hammering and chiseling, including the following steps:

[0022] S1: Billet pretreatment: The precious metal sheet is subjected to low-temperature annealing, with the temperature controlled within the range of 80-120℃ and held at a constant temperature for 25-35 minutes to eliminate residual internal stress from rolling, soften the metal structure, improve ductility, and prevent cracking during subsequent forging. In this embodiment, the low-temperature annealing process adopts the ancient method of holding the precious metal sheet in heated fine sand for uniform heating. The sand temperature is controlled within the range of 80-120℃ to ensure that the temperature of each part of the sheet is consistent and the stress is released evenly.

[0023] S2: Initial billet grading and cold forging shaping: A three-stage layered cold forging and hammering process is used to forge and shape the annealed billet, including:

[0024] Rough hammer leveling stage: The billet is forged using a heavy iron hammer, with a hammering frequency of 145-200 times per unit area. This ensures that the blank has a uniform thickness and a smooth surface;

[0025] Medium-weight hammer forging stage: Using a medium-weight hammer, the main curved surface is forged according to the requirements of the phoenix shape. The height of the main curved surface is controlled between 0.3 and 0.6 cm, thus creating the foundation for the three-dimensional shape.

[0026] Fine hammering and shaping stage: Use a light hammer with a small weight to repeatedly forge the surface, forming a delicate basic texture.

[0027] S3: Split blanking and cutting: According to the split structure design of the phoenix ornament, the forged blank is cut into five independent component blanks: phoenix head blank, chest and abdomen main body blank, double-layer phoenix wing blank, multi-layer phoenix tail blank, and claw and foot blank; among them, the double-layer phoenix wing blank needs to be prepared into two wing blanks of the same shape, and a hollow edge sealing processing allowance of 0.15-0.25mm is reserved on each side for subsequent hollow composite process.

[0028] S4: Three-tiered differentiated chiseling: Employing four types of chisels—flat chisels, line chisels, dot chisels, and curved feather chisels—the process involves three chiseling steps to process the decorative patterns on each component blank, including:

[0029] The process of lightly chiseling out the outline of the sections: use a chisel to lightly chisel out the boundary lines of each decorative area and the outline lines of the main decorative patterns to determine the overall layout;

[0030] The process of chiseling raised relief texture: using flat chisels and dot chisels to chisel out a relief effect in the decorative area, making the decoration appear three-dimensional;

[0031] Deep chiseling of feather-like grooves: Using various chisels, deep feather-like grooves are carved to enhance the layering and realism of the pattern.

[0032] The wing feathers are engraved using a diagonal, staggered arrangement, with the row spacing controlled between 0.4 and 0.6 mm. The phoenix tail uses a layered, staggered engraving technique with long and short feathers alternating to simulate the flowing shape of a real phoenix tail. The chest and abdomen use a dotted down feather engraving technique, with the diameter of the engraving dots controlled between 0.25 and 0.35 mm to create a delicate down feather texture.

[0033] The arc-shaped feather chisel is an arc-shaped chisel with a chisel blade in the shape of a circle with a radius of 2-5mm, used to engrave three-dimensional feather textures on the arc surface of phoenix wings.

[0034] S5: Double-layer hollow phoenix wing composite: After aligning the two phoenix wing blanks, the edges are sealed using a manual hammering process. After reserving an internal cavity, the sealing pretreatment is completed to form a double-layer hollow phoenix wing component. In this embodiment, the cavity thickness of the double-layer phoenix wing is controlled between 0.8 and 1.2 mm. The edges are sealed by hammering at each point, and the weld width does not exceed 0.3 mm to ensure a firm seal and a smooth appearance. The double-layer hollow structure not only reduces the weight of the phoenix wings and avoids deformation caused by their own weight, but also enhances the three-dimensionality and transparency of the phoenix wings.

[0035] S6: Blower Brazing Assembly: A manual blower brazing device is used in conjunction with solder. The manual blower brazing device is a traditional bellows, which controls the flame intensity manually to achieve precise heating at a fixed point. The flame produced by the traditional bellows is gentle, with uniform temperature, concentrated heat, and micro-adjustment. It can precisely heat the gold welding joint, avoiding large-area high-temperature burning, perfectly protecting the thin-walled feathers and intricate hollow patterns of the gold phoenix, and preventing problems such as overheating, deformation, melting, and blackening. The solder is composed of multiple components such as gold, silver, copper, zinc, and tin. The solder formula is free of industrial impurities, suitable for the properties of pure gold substrate, and has a slightly lower melting point. With a thickness lower than pure gold, it has excellent wettability and strong adhesion. After welding, the seams are fully filled, smooth, and seamless, and its color is highly consistent with the gold body. It does not blacken, oxidize, or peel, thus preserving the purity and rustic texture of ancient gold artifacts to the greatest extent. Following the welding sequence of main body first, then accessories, and from thick to thin, the individual components are welded and assembled into a whole piece. The specific welding sequence is as follows: first, the phoenix head and the main chest and abdomen are welded to form the main structure, then the claws, feet, crown, and double-layered hollow phoenix wings are welded in sequence, and finally the multi-layered phoenix tail components are welded. Welding in the order of thickness to thinness and main to secondary components can effectively reduce welding deformation and ensure the stability of the overall structure.

[0036] S7: Traditional Hand Polishing: Using an agate knife, each area is hand-polished, followed by washing with wood ash water to fix the color and brighten the surface, preserving the original hand-hammered texture. The pressure of the agate knife during polishing is controlled at 5-15N, and the polishing is repeated in the same direction until the surface presents a warm and matte texture. The wood ash water washing involves mixing 300-500 mesh wood ash with water in a ratio of 1:8-1:12 and wiping the surface of the workpiece. This removes the surface oxide layer, giving the gold a warm and traditional color, without damaging the hand-hammered texture.

[0041] Rough hammer leveling stage: The billet is forged using a heavy iron hammer, with a hammering frequency of 175 times per unit area. This ensures that the blank has a uniform thickness and a smooth surface;

[0042] Medium-weight hammer forging stage: Using a medium-weight hammer, the main curved surface is forged according to the requirements of the phoenix shape. The height of the main curved surface is controlled at 0.5cm, thus creating the foundation for the three-dimensional shape.

[0043] Fine hammering and shaping stage: Use a light hammer with a small weight to repeatedly forge the surface, forming a delicate basic texture.

[0044] S3: Split blanking and cutting: According to the split structure design of the phoenix ornament, the forged blank is cut into five independent component blanks: phoenix head blank, chest and abdomen main body blank, double-layer phoenix wing blank, multi-layer phoenix tail blank, and claw and foot blank; among them, the double-layer phoenix wing blank needs to be prepared into two wing blanks of the same shape, and a 0.2mm hollow edge sealing processing allowance is reserved on one side for subsequent hollow composite process.

[0045] S4: Three-stage layered differentiated engraving: Four types of engraving tools are used, namely flat engraving, line engraving, dot engraving and curved feather engraving, to process the decoration of each component blank in three engraving processes, including: shallow engraving to outline the boundary lines of the area, medium engraving to raise the relief texture, and deep engraving of the feather grooves;

[0046] The wing feathers are engraved using a diagonal, staggered arrangement, with the row spacing controlled at 0.5mm; the phoenix tail is engraved using a layered, staggered arrangement of long and short feathers, with long and short feathers alternating to simulate the flowing shape of a real phoenix tail; the chest and abdomen are engraved using a dotted down feather technique, with the diameter of the engraved dots controlled at 0.3mm to create a delicate down feather texture;

[0047] The arc-shaped feather chisel is an arc-shaped chisel with a circular arc blade and a radius of 4mm, used to engrave three-dimensional feather textures on the arc surface of phoenix wings.

[0048] S5: Double-layer hollow phoenix wing composite: After aligning the two phoenix wing blanks, the edges are sealed by manual hammering process, and the internal cavity is reserved to complete the sealing pretreatment, forming a double-layer hollow phoenix wing component; In this embodiment, the cavity thickness of the double-layer phoenix wing is controlled at 1mm, and the edges are sealed by point-by-point hammering, with the weld width not exceeding 0.3mm.

[0049] S6: Blow-fire brazing assembly: A manual blow-fire brazing device is used with solder; following the welding sequence of main body first, then accessories, and from thick to thin, the individual components are welded and assembled into a whole; the specific welding sequence is as follows: first weld the phoenix head and the chest and abdomen to form the main structure, then weld the claws, feet, crown, double-layer hollow phoenix wings in sequence, and finally weld the multi-layer phoenix tail components.

[0050] S7: Traditional Hand Polishing: Using an agate knife, each area is hand-polished and polished, followed by washing with wood ash water to fix the color and brighten the surface, preserving the original hand-hammered texture. The pressure of the agate knife during polishing is controlled at 10N, and the polishing is repeated in the same direction until the surface presents a warm and matte texture. The wood ash water washing uses 400-mesh wood ash and water mixed in a 1:8 ratio to wipe the surface of the workpiece, which can remove the surface oxide layer, giving the gold a warm and traditional color, without damaging the hand-hammered texture.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
