Description

Technical Field

[0001] This application relates to the field of gold processing, and more particularly to a dual-rail slide transmission assembly. Background Technology

[0002] In the gold processing industry, to give gold sheets a unique aesthetic appeal and value, various exquisite patterns or designs are often formed on them using die stamping. This process is a crucial step in the production of gold jewelry, requiring not only precision in stamping but also strict adherence to operational safety.

[0003] However, in the traditional gold sheet stamping process, the gold sheets are generally placed into the stamping machine manually. This method poses significant safety hazards. On the one hand, the stamping machine generates enormous pressure and impact during operation; if the operator is not careful, they could be crushed, resulting in serious workplace injuries. On the other hand, manual operation is not only inefficient but also makes it difficult to guarantee the accuracy and consistency of each stamping, thus affecting the quality of the gold sheets.

[0004] Given the aforementioned problems with traditional processing methods, the industry urgently needs a device that can safely and efficiently feed gold sheets into a stamping press for stamping. This device needs to overcome the safety hazards of manual operation while ensuring the accuracy and efficiency of stamping. Utility Model Content

[0030] Embodiments of this application provide a dual-rail slide transmission assembly for feeding gold sheets into a stamping machine, comprising:

[0031] Base;

[0032] Two sliding rods are arranged parallel and symmetrically on both sides of the base;

[0033] A placement platform, which is slidably connected to both of the sliding rods, is on which the gold sheet is placed.

[0034] The dual-rail slide drive assembly allows the slide rods to extend into the external stamping machine, and also allows the placement platform to slide into or out of the stamping machine along the length of the slide rods. The aforementioned dual-rail slide drive assembly ensures the stability and accuracy of the gold sheet during transport by placing it on the placement platform, which is slidably connected to the two slide rods. The sliding connection design allows the placement platform to freely slide into or out of the stamping machine along the length of the slide rods, achieving automated feeding and retrieval of the gold sheet and avoiding the risks associated with direct manual operation of the stamping machine.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] Please see Figures 1-3 This application provides a dual-rail slide transmission assembly 100 for feeding gold sheets into a stamping machine, comprising:

[0037] Base 1;

[0038] Two sliding rods 2 are arranged parallel and symmetrically on both sides of the base 1;

[0039] Placement platform 3, which is slidably connected to two slide rods 2, and the gold sheet is placed on the placement platform 3;

[0040] The dual-rail slide drive assembly 100 allows the slide rod 2 to extend into the external stamping machine, and the dual-rail slide drive assembly 100 allows the placement platform 3 to slide into or out of the stamping machine along the length direction of the slide rod 2.

[0041] Specifically, the base 1 serves as the supporting structure for the entire double-rail slide transmission assembly 100. The base 1 provides a stable mounting platform for the slide bar 2 and the placement table 3, ensuring that the assembly will not shake or tilt due to external forces during operation, thus improving overall stability and reliability. The slide bar 2 serves as the track for the placement table 3, allowing it to move along its length. The placement table 3 carries the gold sheet and, through its sliding connection with the slide bar 2, facilitates the transport of the gold sheet. The design of the slide bar 2 allows it to extend into the press, enabling the gold sheet on the placement table 3 to be directly fed into the press for processing. The sliding of the placement table 3 on the slide bar 2 enables the feeding and unloading of the gold sheet. This design makes the gold sheet transport process more flexible and controllable, improving the automation level of the entire production line. As the supporting structure for the entire transmission assembly, the base 1 needs to withstand significant weight and force; therefore, it is typically made of high-strength, high-rigidity materials such as cast iron, steel, or aluminum alloy. The base 1 can be designed as a flat plate with sufficient area and thickness to ensure its stability and load-bearing capacity. To facilitate the installation and fixation of the slide bar 2, the base 1 can be provided with holes or slots matching the diameter of the slide bar 2, so that the slide bar 2 can be accurately installed on the base 1. The slide bar 2 needs to bear the weight of the placement platform 3 and the gold sheet on it, and maintain straightness and stability during sliding; therefore, it is usually made of high-strength, wear-resistant materials, such as stainless steel, alloy steel, or carbon fiber. The slide bar 2 can be designed in cylindrical or square cross-sectional shapes to adapt to different sliding requirements and installation conditions. The length of the slide bar 2 should be determined according to the size of the stamping machine and the conveying distance of the gold sheet to ensure that the placement platform 3 can slide smoothly into and out of the stamping machine. The placement platform 3 needs to support the gold sheet and maintain stability and accuracy during sliding; therefore, it is usually made of lightweight, high-strength, wear-resistant materials, such as aluminum alloy, copper, or stainless steel. In particular, considering the non-magnetic properties of the gold sheet and possible chemical reactions, copper may be a better choice, as it will not chemically react with gold or cause magnetic interference to the gold sheet. The placement platform 3 can be designed as a flat plate with sufficient area and thickness to support the gold sheet and maintain its stability. In order to slide and connect with the slide bar 2, a sliding component 32 (such as a sliding bearing, slider, etc.) that matches the diameter of the slide bar 2 can be provided on the placement platform 3 to ensure that the placement platform 3 slides smoothly on the slide bar 2.

[0042] In one specific example, the placement platform 3 is made of copper.

[0043] Specifically, copper is a material with excellent corrosion resistance, especially when in contact with gold. Gold is a chemically very stable metal that does not readily react with other substances. However, under certain extreme conditions (such as high temperature, high pressure, or the presence of certain chemicals), gold may react with other metals, leading to surface discoloration or a decline in quality. Copper, as an inert metal, has extremely low chemical reactivity with gold; therefore, using copper as the material for the placement platform 3 ensures that the gold sheet maintains its original quality and appearance during transport and processing. Copper has good thermal conductivity, meaning it can effectively transfer heat. During stamping, the gold sheet may generate heat due to the pressure from the die. If the material of the placement platform 3 has poor thermal conductivity, this heat may accumulate on the platform, causing uneven heating or deformation of the gold sheet. Using copper as the material for the placement platform 3 ensures that heat can be quickly transferred away, thus maintaining the stability and quality of the gold sheet.

[0044] In a specific example, the placement platform 3 has a placement surface 31 on its outer side, and the gold sheet is placed on the placement surface 31. The length direction of the slide rod 2 is parallel to the placement surface 31. The direction perpendicular to the placement surface 31 is denoted as the first direction. The thickness 'a' of the placement platform 3 in the first direction satisfies the relationship: 100mm ≥ a ≥ 80mm.

[0045] Specifically, the outer side of the placement platform 3 is designed with a flat placement surface 31, specifically for placing gold sheets. The design of the placement surface 31 ensures that the gold sheets can be placed stably on it, preventing them from slipping or being damaged during transport. The length direction of the slide bar 2 is parallel to the placement surface 31, meaning that when the placement platform 3 slides on the slide bar 2, the gold sheets on the placement surface 31 maintain a stable orientation and position. This design ensures that the gold sheets are not damaged by tilting or shaking of the placement platform 3 during transport. The direction perpendicular to the placement surface 31 is defined as the first direction. This direction is the main force direction when the placement platform 3 slides on the slide bar 2, and it is also the direction in which the gold sheets may be compressed or deformed. The thickness 'a' of the placement platform 3 in the first direction is designed to satisfy the relationship: 100mm ≥ a ≥ 80mm. This thickness range is chosen based on considerations of multiple factors, including the thickness of the gold sheets, the strength of the placement platform 3, the dimensions of the slide bar 32, and the stability of the slide bar 2. A thicker placement platform 3 can provide better stability and load-bearing capacity, but it will also increase the overall weight and cost of the equipment. Therefore, while ensuring stability and load-bearing capacity, it is necessary to minimize the thickness of the placement platform 3 as much as possible to reduce the weight and cost of the equipment.

[0046] In one specific example, the base 1 includes two support plates 11, and the two ends of the slide rod 2 are respectively fixed to the two support plates 11.

[0047] Specifically, the base 1 consists of two support plates 11, which are the main load-bearing structures of the base 1. They are typically designed with sufficient strength and rigidity to support the weight of the slide rod 2, the placement platform 3, and the gold sheet placed on the placement surface 31. These two support plates 11 are usually arranged parallel to ensure that the slide rod 2 maintains a stable straightness between them. The distance between the support plates 11 should be wide enough to provide sufficient space for installing the slide rod 2 and the placement platform 3, while ensuring the stability of the entire structure. Both ends of the slide rod 2 are fixed to the two support plates 11 respectively. This fixing method ensures the stability and firmness of the slide rod 2 on the base 1, allowing the placement platform 3 to slide smoothly on the slide rod 2. The connection between the slide rod 2 and the support plates 11 can be achieved in various ways, such as welding, bolting, threading, or pinning. The specific connection method chosen depends on application requirements, material properties, and cost considerations. For example, welding can provide strong connection strength and stability, but may not be suitable for scenarios requiring frequent disassembly or adjustment; while bolting provides greater flexibility and disassembly. When fixing the slide rod 2 to the support plate 11, it is necessary to ensure that the center line of the slide rod 2 is aligned with the center line between the two support plates 11 to maintain the straightness and stability of the slide rod 2. This usually requires the use of positioning tools or measuring equipment for precise installation and adjustment. By fixing both ends of the slide rod 2 to the two support plates 11 respectively, the stability of the entire structure can be ensured, so that the placement platform 3 will not be damaged due to shaking or tilting during the sliding process. The design of the two support plates 11 provides sufficient load-bearing area and strength to support the weight of the entire device, including the slide rod 2, the placement platform 3, and the gold sheet.

[0048] In one specific example, the support plate 11 has a support surface 111, the support surfaces 111 on the two support plates 11 are parallel, and the support surface 111 is parallel to the placement surface 31, and the slide rod 2 is set to protrude from the support surface 111.

[0049] Specifically, each support plate 11 is designed with a support surface 111. This support surface 111 is the main functional part of the support plate 11, used to provide stable support and positioning. The support surfaces 111 on the two support plates 11 are parallel. This parallelism ensures that the slide bar 2 can maintain a stable straightness between them, thereby ensuring the smoothness and accuracy of the sliding of the placement platform 3 on the slide bar 2. The support surface 111 is parallel to the placement surface 31. This parallel relationship ensures that the gap between the placement platform 3 and the support plate 11 remains consistent during the sliding process, avoiding problems such as friction, shaking, or tilting caused by non-parallelism. The parallel design of the support surface 111 and the placement surface 31 makes the entire structure more functionally coordinated. The support surface 111 provides stable support, while the placement surface 31 is used to support the gold sheet. The parallel relationship between the two ensures the stability and quality of the gold sheet during transportation and processing. The slide bar 2 is set to protrude from the support surface 111. This means that a portion of the slide bar 2 (usually a cylindrical part) extends from the support surface 111 to engage with the sliding element 32 (such as a slide rail, roller, etc.) under the placement platform 3, enabling the placement platform 3 to slide. When the slide bar 2 protrudes from the support surface 111, its centerline must be aligned with the centerline of the support surface 111 to maintain the straightness and stability of the slide bar 2. This typically requires precise installation and adjustment using positioning tools or measuring equipment. The parallel design of the support surface 111, the placement surface 31, and the slide bar 2 ensures the stability of the entire structure. This stability is crucial for ensuring the quality and precision of the gold sheet during transport and processing.

[0050] In one specific example, the dual-rail slide drive assembly 100 further includes:

[0051] Fixing component 4: Each end of the slide rod 2 is respectively fitted with a fixing component 4. The fixing component 4 is detachably connected to the support plate 11. The slide rod 2 is fixedly connected to the support plate 11 through the fixing component 4.

[0052] Specifically, in the double-rail slide transmission assembly 100, a fixing member 4 is fitted at each end of the slide rod 2. This fixing member 4 is a key component connecting the slide rod 2 and the support plate 11, ensuring that the slide rod 2 can be stably fixed to the support plate 11. The main function of the fixing member 4 is to provide a connection point between the slide rod 2 and the support plate 11, and to achieve a detachable connection through some means (such as bolts, nuts, clips, etc.). This design makes the connection between the slide rod 2 and the support plate 11 both strong and flexible, facilitating installation, disassembly, and maintenance. The connection between the fixing member 4 and the support plate 11 is detachable. This means that the slide rod 2 can be easily removed from or reinstalled on the support plate 11 without damaging any components. This design provides greater flexibility and convenience, especially when it is necessary to adjust or replace the slide rod 2. The connection method between the fixing member 4 and the support plate 11 can be selected according to specific application requirements and material properties. For example, the fixing member 4 can be fastened to the support plate 11 using bolts and nuts, or mechanical connection methods such as clips and slots can be used. Regardless of the connection method chosen, it is essential to ensure the connection is secure and stable.

[0053] In one specific example, the dual-rail slide drive assembly 100 further includes:

[0054] A fastening screw 5 is provided on the fixing member 4. The fixing member 4 allows the fastening screw 5 to be screwed into or out of the fixing member 4. When the fastening screw 5 is screwed into the fixing member 4, the fixing member 4 abuts against the slide rod 2.

[0055] Specifically, in the double-rail slide transmission assembly 100, the fastening screw 5 is a key component located on the fixing member 4. Its main function is to provide additional fastening force, ensuring that the slide rod 2 can be firmly fixed to the support plate 11. The fastening screw 5 is usually designed to be on the outside of the fixing member 4 or in an easily accessible location for easy operation and maintenance. It can be in the form of a threaded hole or a sleeve with internal threads, for mating with corresponding bolts or screws. The fixing member 4 is designed to allow the fastening screw 5 to be screwed in or out of its interior. This design allows the fastening screw 5 to be easily adjusted in depth into the fixing member 4, thereby controlling the fastening force of the fixing member 4 on the slide rod 2. When the fastening screw 5 is screwed into the fixing member 4, it gradually contacts the slide rod 2 and applies pressure. This contact action ensures that the slide rod 2 is firmly clamped between the fixing member 4 and the support plate 11, thereby preventing the slide rod 2 from shaking or falling off during sliding. The main function of the fastening screw 5 is to provide sufficient fastening force to ensure a firm and reliable connection between the slide rod 2 and the support plate 11. This fastening force can be controlled by adjusting the screw depth of the fastening screw 5 to adapt to different application requirements and material properties.

[0056] In one specific example, the fastener 4 is bolted to the support plate 11.

[0057] Specifically, bolted connections are a common type of mechanical connection that uses bolts (usually with nuts) to tightly fasten two or more parts together. Bolted connections offer advantages such as simple structure, reliable connection, and easy disassembly, and are widely used in various machines and equipment. Here, "fixed member 4" and "support plate 11" are the two components being connected. Fixed member 4 is typically used to fix or support other components (such as slide bar 2), while support plate 11 provides a stable base for mounting these components. Bolts are the key fasteners connecting fixed member 4 and support plate 11. Bolts typically pass through pre-drilled holes in fixed member 4 and are screwed into threaded holes in support plate 11, or are fitted with nuts through through holes in support plate 11, thus achieving a tight connection between the two components. During the connection process, tools such as wrenches and screwdrivers may be used to tighten the bolts or nuts to ensure a secure and reliable connection between fixed member 4 and support plate 11. Additionally, washers, locking washers, and other auxiliary components may be used to increase the tightness of the connection and prevent loosening. A significant advantage of bolted connections is their detachability. This means that the fastener 4 can be easily removed from or reinstalled on the support plate 11 without damaging any components. This flexibility is very useful when maintaining, upgrading, or replacing parts of the equipment.

[0058] In a specific example, the placement platform 3 includes a platform body 33 and two sliding members 32 disposed on the platform body 33. The gold sheet is placed on the platform body 33, and the two sliding members 32 are respectively sleeved on the two sliding rods 2.

[0059] Specifically, the platform 33, as the foundation of the placement platform 3, primarily bears the responsibility of supporting and fixing the gold sheet. Its design often needs to consider factors such as the size and weight of the gold sheet, as well as ease of operation, ensuring that the gold sheet can be stably placed on the platform 33 while facilitating related operations by the operator. The sliding component 32, as a key component connecting the platform 33 and the slide bar 2, is usually designed with a structure that matches the shape of the slide bar 2 for a tight fit. The number, position, and size of the sliding components 32 need to be rationally designed based on factors such as sliding requirements, load capacity, and stability requirements in the actual application scenario. The main function of the platform 33 is to provide a stable and flat support surface 111, ensuring that the gold sheet remains stable during placement, processing, or transportation, preventing wobbling or tilting. Through the connection between the sliding component 32 and the slide bar 2, the placement platform 3 can slide smoothly along the slide bar 2, thereby achieving position adjustment. This design not only improves work efficiency but also enhances operational flexibility. The sliding element 32 and the sliding rod 2 are connected by a sleeve connection, meaning the sliding element 32 is tightly sleeved on the sliding rod 2. This connection method is simple and effective, ensuring smooth sliding while reducing frictional loss between the connecting parts. During sliding, a good sliding fit needs to be maintained between the sliding element 32 and the sliding rod 2. This typically requires the surfaces of both the sliding element 32 and the sliding rod 2 to be smooth, flat, and have a certain degree of wear resistance to reduce sliding resistance and improve sliding efficiency.

[0060] In one specific example, the sliding member 32 is bolted to the platform 33.

[0061] Specifically, bolted connections are a common type of mechanical connection that uses bolts (usually with nuts) to tightly fasten two or more parts together. This connection method has advantages such as simple structure, reliable connection, and convenient disassembly, and is widely used in various machines and equipment. Here, "sliding element 32" and "platform 33" are the two components being connected. Sliding element 32 is typically used to provide a contact surface with slide rod 2 or other sliding guides to achieve smooth sliding movement. Platform 33 serves as the basic structure supporting sliding element 32 and other components. Bolts are the key fasteners connecting sliding element 32 and platform 33. Bolts typically pass through pre-drilled holes in sliding element 32 and are screwed into threaded holes in platform 33, or they engage with through holes in platform 33 through nuts, thereby achieving a tight connection between the two components. During the connection process, tools such as wrenches and screwdrivers are needed to tighten the bolts or nuts to ensure a firm and reliable connection between sliding element 32 and platform 33. Additionally, to increase the tightness of the connection and prevent loosening, auxiliary components such as washers and locking washers may also be used. A significant advantage of bolted connections is their detachability. This means that the sliding element 32 can be easily removed from or reinstalled on the platform 33 without damaging any components. This flexibility is extremely useful when maintaining, upgrading, or replacing parts of the equipment.

[0062] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
