Description
TECHNICAL FIELD
[0001] The present application relates to the field of gold processing, and in particular to a jig. BACKGROUND
[0002] In the process of making a gold globe, a crucial step is to produce a plurality of precisely shaped gold sectorial spherical pieces. These sectorial spherical pieces, as the basic units that make up the globe sphere, directly affect the appearance and texture of the final product. However, traditional processing methods have significant technical problems in this link.
[0003] Traditionally, the processor needs to manually place the gold sheet on the spherical mold, then press it to fit the mold surface by hand, and then cut it by hand. This process not only requires the processor to have superb hand skills, but also requires a high degree of patience and concentration to ensure that the shape, size and curvature of each sectorial spherical piece meet the design requirements. However, even experienced craftsmen can become fatigued during long periods of manual operation, which can affect processing accuracy and efficiency.
[0004] The traditional method relies on manual cutting to make the required sectorial spherical pieces, which is not only time-consuming and labor-intensive, but also difficult to ensure cutting accuracy, which can lead to problems such as uneven size and irregular shape between sectorial spherical pieces. These problems are further amplified during the subsequent assembly process, resulting in a globe sphere with a rough surface that severely affects the product's aesthetic appeal and overall quality.
[0005] In summary, the traditional gold sectorial spherical piece processing method has significant problems such as high operating difficulty, low production efficiency and unstable product quality. These problems not only increase production costs, but also limit the large-scale production and widespread application of gold globes. Therefore, developing a new technology that can efficiently and accurately process gold sectorial spherical pieces has become a technical problem that needs to be solved in the industry.

[0034] Embodiments of the present application provide a jig for processing a gold sector spherical sheet, comprising:
[0035] A first extrusion member, the first extrusion member having a first sector spherical surface protruding from the first extrusion member.
[0036] A second extrusion member, the second extrusion member having a second sector spherical surface corresponding to the first sector spherical surface, the second sector spherical surface being recessed into the second extrusion member.
[0037] The second extrusion member allows the first sector spherical surface to completely fit on the second sector spherical surface, and the first extrusion member allows the second sector spherical surface to completely fit on the first sector spherical surface. The jig provided above is designed with a protruding first sector spherical surface on the first extrusion member and a recessed second sector spherical surface on the second extrusion member, and the two spherical surfaces completely correspond in shape and size. This design allows the first sector spherical surface to completely fit on the second sector spherical surface, so that the gold sheet can be pressed into a sector spherical sheet between the first extrusion member and the second extrusion member during processing. By using this jig, the processor no longer needs to manually press the gold sheet on the spherical mold, and the structure design of the jig itself ensures the accurate forming of the sector spherical sheet. This greatly simplifies the processing flow, reduces the operation difficulty, and improves the production efficiency and product quality.
[0038] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0039] Please refer to Figures 1-7 Embodiments of the present application provide a jig 100 for processing a gold sector spherical sheet, comprising:
[0040] A first extrusion member 1, the first extrusion member 1 having a first sector spherical surface 6 protruding from the first extrusion member 1.
[0041] A second extrusion 2 having a second sector spherical surface 8 corresponding to the first sector spherical surface 6, the second sector spherical surface 8 is recessed into the second extrusion 2.
[0042] The second extrusion 2 allows the first sector spherical surface 6 to fit onto the second sector spherical surface 8 completely, and the first extrusion 1 allows the second sector spherical surface 8 to fit onto the first sector spherical surface 6 completely.
[0043] Specifically, the first extrusion 1 has a protruding first sector spherical surface 6 as part of the forming die, which is responsible for forming the outer surface of the gold sector spherical sheet during extrusion. Its protruding design helps to provide sufficient support and shape definition during extrusion. The second extrusion 2 has a recessed second sector spherical surface 8 corresponding to the first sector spherical surface 6 as another part of the forming die, which is responsible for cooperating with the first sector spherical surface 6 during extrusion to form the shape of the gold sector spherical sheet together. Its recessed design helps to provide uniform extrusion pressure during extrusion. The second extrusion 2 allows the first sector spherical surface 6 to fit onto the second sector spherical surface 8 completely, and vice versa. It ensures that the two sector spherical surfaces can fit tightly during extrusion to form a complete gold sector spherical sheet shape. It eliminates the gap and error in the forming process, improves the precision and aesthetics of the product.
[0044] In a specific example, the median plane of the first sector spherical surface 6 is referred to as the first plane a, and a plane perpendicular to the first plane a is referred to as the second plane b. The first extrusion 1 also has two first shear planes 5, which are symmetrically arranged on both sides of the first plane a, and both of the first shear planes 5 are perpendicular to the second plane b. The first shear plane 5 intersects the first sector spherical surface 6.
[0045] Specifically, the median plane of the first sector spherical surface 6 refers to a plane that evenly divides the first sector spherical surface 6 into two symmetrical parts. This plane is a theoretical construction line used to determine the position and angle of the first shear planes 5. The second plane b is a plane perpendicular to the first plane a. In three-dimensional space, two planes being perpendicular means that their normal vectors are perpendicular to each other. The introduction of the second plane b is to define the direction of the first shear planes 5, ensuring that they form a specific angle with the first plane a. The first shear planes 5 are two planes located on the outside of the first extrusion 1, symmetrically arranged on both sides of the first plane a. This means that each shear plane is located on one side of the first sector spherical surface 6 and is symmetrical to the median plane. Both first shear planes 5 are perpendicular to the second plane b. This means that the direction of the shear planes is perpendicular to the vertical plane of the median plane, ensuring the consistency of the shearing operation. Both first shear planes 5 intersect the first sector spherical surface 6. This means that after extrusion molding, when the gold sector spherical sheet needs to be sheared, the shearing operation will be carried out along these predefined shear planes. The intersection of the first shear planes 5 and the first sector spherical surface 6, both of which are located on the outside of the first extrusion 1, indicates that the two first shear planes 5 are designed as the two sides of the first cutting element, and the first sector spherical surface 6 is designed as one end of the first extrusion 1, while the two first cutting planes are designed as the two sides of the first extrusion 1. Through the predefined first shear planes 5, it can be ensured that after extrusion molding, the gold sector spherical sheet can be sheared along the precise position and angle, thereby improving the precision and consistency of the product.
[0046] In a specific example, the median plane of the second sector spherical surface 8 is referred to as the third plane c, and a plane perpendicular to the third plane c is referred to as the fourth plane d. The second extrusion 2 also has two second shear planes 7 on the outside, which are symmetrically arranged on both sides of the third plane c, and both second shear planes 7 are perpendicular to the fourth plane d. The first shear planes 5 intersect the first sector spherical surface 6;
[0047] When the first sector spherical surface 6 completely fits the second sector spherical surface 8, the second shear planes 7 correspond one-to-one to the first shear planes 5 and intersect the first shear planes 5.
[0048] Specifically, the third plane c is the median plane of the second sector spherical surface 8, which evenly divides the second sector spherical surface 8 into two symmetrical parts. This plane is a theoretical construction line used to determine the position and angle of the second shear planes 7. The fourth plane d is a plane perpendicular to the third plane c. In three-dimensional space, two planes being perpendicular means that their normal vectors are perpendicular to each other. The introduction of the fourth plane d is to define the direction of the second shear planes 7, ensuring that they form a specific angle with the third plane c. The second shear planes 7 are two planes located on the outside of the second extrusion 2, symmetrically arranged on both sides of the third plane c. This means that each shear plane is located on one side of the second sector spherical surface 8 and is symmetrical to the median plane. Both second shear planes 7 are perpendicular to the fourth plane d. This ensures that the direction of the shear planes is perpendicular to the perpendicular plane of the median plane, consistent with the direction of the first shear planes 5, thereby ensuring the consistency of the shearing operation. Both second shear planes 7 intersect the second sector spherical surface 8. After extrusion molding, the shearing operation will be carried out along these predefined shear planes, ensuring the accurate separation of the golden sector spherical sheet. The intersection of the second shear planes 7 and the second sector spherical surface 8, both of which are also located on the outside of the second extrusion 2, indicates that the two second shear planes 7 are designed as the two sides of the second cutting element, while the second sector spherical surface 8 is designed as one end of the second extrusion 2, and the two second cutting planes are designed as the two sides of the second extrusion 2. When the first sector spherical surface 6 is completely fitted on the second sector spherical surface 8, it means that the two sector spherical surfaces are in close contact during the extrusion process, forming a complete golden sector spherical sheet shape. In this completely fitted state, the second shear planes 7 correspond to and intersect the first shear planes 5 one by one. This means that during the shearing operation, the first and second shear planes 7 will act on both sides of the golden sector spherical sheet at the same time, ensuring the consistency and accuracy of the shearing.
[0049] In a specific example, the two first shear planes 5 are spaced apart, and the two second shear planes 7 are spaced apart.
[0050] Specifically, "two said first cutting surfaces 5 are spaced apart": this means that there is a certain space or distance between the two first cutting surfaces 5. In other words, these two surfaces are not immediately adjacent, but have a certain interval. This interval arrangement may be to accommodate other components, provide necessary movement space, or meet specific functional requirements. "And two said second cutting surfaces 7 are spaced apart": similar to the first cutting surfaces 5, there is also an interval between the two second cutting surfaces 7. This means that they are also not immediately adjacent, but have a certain spatial separation. This interval arrangement may also be for various reasons, such as accommodating other components, providing movement space, or meeting specific design requirements. The interval arrangement is because the globe has a rotating rod, and the interval arrangement can still have an area for the rotating rod to pass through after the fan-shaped spherical pieces are spliced into a spherical body. In the design of the globe, the rotating rod is a key component that allows the globe to rotate freely so that users can observe the Earth from different angles. To achieve this, the spherical body of the globe is usually spliced from multiple fan-shaped spherical pieces. These fan-shaped spherical pieces need to ensure that they can form a complete sphere when spliced, while also reserving a space for the rotating rod to pass through the sphere. The "interval arrangement" mentioned here is to meet this requirement. These cutting surfaces correspond to the cutting edges on the fan-shaped spherical pieces, and they are designed to be spaced apart so that after the fan-shaped spherical pieces are spliced into a spherical body, these intervals can converge into a central area. This central area is the space that the rotating rod will pass through. By spacing these cutting surfaces, designers can ensure that there is still a large enough space in the spherical body to accommodate the rotating rod after the fan-shaped spherical pieces are spliced.
[0051] In a specific example, the jig 100 also includes a first fixing part 3, which is provided on the first extrusion part 1. The jig 100 allows the first fixing part 3 to be bolted to external stamping equipment.
[0052] Specifically, the first fixing part 3 is provided on the first extrusion part 1. This means that the first fixing part 3 is closely related or integrated with the first extrusion part 1, and they together constitute part of the jig 100. The first extrusion part 1 may be a component with a specific shape and function, used to apply pressure or perform other operations during processing, while the first fixing part 3 is responsible for fixing or connecting the jig 100 to external equipment. The first fixing part 3 is designed with threaded holes or bolt holes that match the bolts, allowing external equipment to be connected to the jig 100 through bolts. Bolt connection is a common and reliable connection method that can generate enough clamping force by tightening the bolts, ensuring a firm connection between the jig 100 and external equipment. Bolt connection allows quick connection and disconnection between the jig 100 and external equipment, facilitating the replacement of the jig 100 or maintenance.
[0053] In one embodiment, the first fixed part 3 is integrally formed with the first extrusion 1.
[0054] In particular, integrally formed components are typically made of the same material to ensure the strength of the bond between them and the overall performance. In the case of the jig 100, this material can be high-strength steel, aluminum alloy, or other metals suitable for withstanding shear forces and fixing tasks. Integrally forming can be achieved through casting, forging, injection molding (for plastic components), or other forming techniques. For metal components, common forming methods include stamping, die casting, or precision casting. These methods allow manufacturers to produce components with complex shapes and precise dimensions in a single operation. Since the first fixed part 3 and the first extrusion 1 are formed in the same manufacturing process, there are no seams or connection points between them, which enhances the structural integrity and strength. This design reduces the risk of component failure due to the failure of seams or connection points. The integrally formed design can typically reduce the number and weight of components, as additional connecting pieces (such as bolts, nuts, or welding materials) are not required. This helps to reduce costs and improve production efficiency. The stamping device can be a device such as a punch press that can provide pressure to the gold raw material to be processed through the first fixed part 3 and the first extrusion part to form.
[0055] In one embodiment, the first fixed part 3 and the first extrusion 1 are both made of copper.
[0056] In particular, copper is a metal with excellent electrical conductivity, thermal conductivity, and ductility. It also has good corrosion resistance and can maintain its performance under various environmental conditions. Copper has a relatively high density, but its strength is moderate, making it suitable for a variety of mechanical applications. Due to these characteristics of copper, it is often used in electrical connections, heat exchangers, piping systems, and other applications that require good electrical conductivity and thermal conductivity. The main function of the first fixed part 3 is to fix the jig 100 or connect it to external equipment. Therefore, it needs to have sufficient strength and stability to withstand the load during operation. Gold hot pressing is a common processing technique that takes advantage of the plastic deformation characteristics of gold at high temperatures by applying pressure to cause it to deform and obtain the desired shape. In this process, heating is an essential step that makes the gold material softer, facilitating subsequent forming operations. Copper is a metal with very high thermal conductivity, with excellent thermal conductivity. In metal processing, this property of copper is often used to accelerate heat transfer, thereby achieving rapid cooling or heating. When gold is heated, if copper is needed to help it cool quickly into shape, the high thermal conductivity of copper will play a key role. Copper can quickly transfer heat away from the gold, allowing it to cool quickly and solidify, thereby maintaining the desired shape and size.
[0057] In one embodiment, the jig 100 further comprises:
[0058] A second fixing portion 4 is provided on the second extruding member 2. The jig 100 allows the second fixing portion 4 to be bolted to an external stamping device.
[0059] Specifically, the second fixing portion 4 is mounted on the second extruding member 2. The second extruding member 2 can be a movable component in the jig 100, used to apply pressure or perform other mechanical operations during processing. The position of the second fixing portion 4 can be chosen based on the fixed force it needs to provide or the location requirements of the connection point. The jig 100 allows the second fixing portion 4 to be bolted to an external stamping device: This sentence describes the connection method between the second fixing portion 4 and the external device. Bolt connection is a common mechanical connection method that uses bolts and nuts to tightly fix two or more components together. Here, the design of the jig 100 allows the second fixing portion 4 to be connected to the external device through bolts, which provides a firm connection and reliable fixation. The main function of the second fixing portion 4 is to provide a fixed point, allowing the jig 100 to be stably fixed to the external device. This helps to ensure the stability and accuracy of the jig 100 during processing. At the same time, the bolt connection method also allows the jig 100 to be quickly disassembled and reassembled with the external device, improving production efficiency and flexibility. Through bolt connection, the jig 100 can adapt to different sizes and types of external devices. This design makes the jig 100 more versatile and adaptable, able to meet a variety of processing needs. The external stamping device can be a stamping machine or other device that can provide pressure. The external stamping device applies pressure to the gold raw material to be processed through the second fixing portion 4 and the second extruding portion to form a shape.
[0060] In one embodiment, the second fixing portion 4 is integrally formed with the second extruding member 2.
[0061] In particular, the integrally formed components are typically made of the same material to ensure the bonding strength and overall performance between them. For the second fixing portion 4 and the second extrusion 2, they can be made of metal (such as stainless steel, aluminum alloy, or copper alloy) or other formable materials, depending on the application environment and performance requirements of the jig 100. The integral forming can be achieved by casting, forging, injection molding (for plastic components), or other forming techniques. For metal components, common forming methods include stamping, die casting, or precision casting. These methods allow manufacturers to manufacture components with complex shapes and precise dimensions in a single operation, while ensuring seamless connection between the second fixing portion 4 and the second extrusion 2. Since the second fixing portion 4 and the second extrusion 2 are formed in the same manufacturing process, there is no joint or connection point between them, which enhances the structural integrity and strength. This design reduces the risk of component damage due to joint or connection point failure, improving the reliability and durability of the jig 100.
[0062] In a specific example, the second extrusion 2 and the second fixing portion 4 are both made of copper.
[0063] In particular, copper is a metal with excellent electrical conductivity, thermal conductivity, and ductility. It also has good corrosion resistance and can maintain its performance under various environmental conditions. Copper has a relatively high density, but moderate strength, suitable for various mechanical applications. In addition, copper has good processability and can be formed by casting, forging, machining, and other methods. The second extrusion 2 can be used to apply pressure, shear force, or other forms of mechanical force during processing. Therefore, it needs to have sufficient strength and hardness to withstand these forces without deformation or damage. At the same time, since heat may be generated during the extrusion process, the material also needs to have good thermal conductivity to dissipate heat. The strength and ductility of copper make it an ideal choice for extrusion components. It can be accurately manufactured to the desired shape and size through various forming techniques. In addition, the good thermal conductivity of copper helps dissipate heat during extrusion, preventing the component from overheating. The main function of the second fixing portion 4 is to provide a fixing point or connection point to fix the jig 100 or other components on the jig 100 to external equipment. Therefore, it needs to have sufficient strength and stability to withstand the load during operation. Components of the same material have similar coefficients of thermal expansion. This means that the relative size change between the two components will be predictable when the temperature changes, helping to ensure the stability and accuracy of the jig 100 during operation. Copper is good at conducting heat, which can quickly transfer heat from gold, allowing it to cool quickly and solidify, thus maintaining the desired shape and size.
[0064] The above merely describes the embodiments of the present application, and it should be pointed out that, for those skilled in the art, improvements can be made without departing from the inventive concept of the present application, and these all belong to the protection scope of the present application.
