Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, specifically to an extrusion molding equipment for silver-copper rods. Background Technology

[0002] Silver-copper alloy rods, with their superior electrical and thermal conductivity, corrosion resistance, and excellent machinability, occupy a core position in key fields such as electronics, power, and communications. From the internal wires of precision electronic components to the radio frequency transmission lines of high-end communication equipment, from the conductors of special cables in power systems to the core connecting components in the new energy field, the performance of silver-copper rods directly affects the reliability and stability of end products.

[0003] Traditional silver-copper rod extrusion dies have significant limitations in material and structural design, which restricts the molding quality. In terms of materials, ordinary alloy steel has insufficient ability to maintain high-temperature hardness, is prone to rapid wear during extrusion, has a short service life, and has poor resistance to thermal fatigue, making it prone to microcracks. In terms of structure, the single-hole straight-through die flow channel causes uneven metal flow, generating shear stress, which leads to transverse cracks on the surface of the rod.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figure 1 This utility model provides a technical solution: a silver-copper rod extrusion molding equipment, including a main body 1, a base plate 2 installed on the main body 1, an extrusion force module 3 installed above the base plate 2, a hydraulic device 5 installed above the extrusion force module 3, a fixing plate 6 installed above the hydraulic device 5, and a support frame 4 installed above the fixing plate 6.

[0019] The base plate 2 includes a positioning seat 8, and a support plate 7 is installed below the positioning seat 8. A material passage 9 is provided in the middle of the support plate 7.

[0020] In this embodiment, the ingenious combination of the positioning seat and the support plate provides precise positioning for the placement base plate, ensuring extremely high stability throughout the entire equipment operation. The material inlet not only ensures smooth material flow within the equipment but also significantly increases the material turnover speed, thereby improving overall production efficiency.

[0021] The extrusion force module 3 includes a double-layer shell 11, with a power interface 12 installed on the top of the double-layer shell 11, a heating wire 13 installed below the power interface 12, and a diversion mold 14 installed inside the double-layer shell 11.

[0022] In this embodiment, the double-layered shell of the extrusion force module integrates the power interface, heating wire, and flow divider die. This integrated design offers multiple advantages. Firstly, the heating wire heats the material, optimizing the forming quality and resulting in a more stable and reliable final product. Secondly, the double-layered shell encloses the power interface, heating wire, and flow divider die, providing excellent protection against external interference and effectively extending the equipment's lifespan.

[0023] The flow divider mold 14 includes a flow divider cone 15, and forming die holes 16 are provided around the flow divider cone 15. The flow divider mold 14 is made entirely of cemented carbide and has multiple forming die holes 16 on it.

[0024] In this embodiment, the flow divider die is made of cemented carbide, a material with high strength and wear resistance. The combination of a flow divider cone and multiple forming die orifices ensures uniform material feeding as it enters the die. This guarantees an appropriate material supply to each forming die orifice, resulting in efficient production. Furthermore, this design reduces equipment maintenance costs because uniform feeding minimizes wear on the die caused by excessive localized pressure or uneven material distribution.

[0025] The bottom end of the hydraulic column 10 located below the hydraulic device 5 is provided with a conical groove that fits the size of the flow divider cone 15.

[0026] In this embodiment, the hydraulic column of the hydraulic device is precisely fitted with the flow divider cone to ensure stable hydraulic transmission and improve the molding accuracy of the product during the molding process.

[0027] The inner layer of the double-layer shell 11 is made of silicon carbide ceramic material, while the outer layer is made of high-strength steel, which takes into account both heat resistance and rigidity.

[0028] In this embodiment, the inner layer of the double-layered outer shell is made of silicon carbide ceramic, a material with excellent heat resistance that maintains stable performance in high-temperature environments. The outer layer is made of high-strength steel, whose robust properties provide solid structural support for the entire device. This combined inner and outer layer design allows the device to stably withstand high-temperature environments and ensures structural safety and reliability during long-term operation.

[0029] Working Principle: In actual operation, the first step is to place the flow-dividing cone 15 of the flow-dividing mold 14 upwards at the bottom of the double-layered outer shell 11. Ensure good contact and accurate positioning between the flow-dividing cone 15 and the bottom of the double-layered outer shell 11. Next, the extrusion force-bearing module 3 is fixed in the designated position by placing the positioning seat 8 on the base plate 2. In this process, the positioning seat 8 plays a crucial role in positioning and fixing, ensuring that the extrusion force-bearing module 3 will not shift during subsequent operations, thereby ensuring the operational stability of the entire equipment.

[0030] Next, the material is placed inside the double-layered outer shell 11. The amount and method of material placement are also subject to certain requirements. The amount must be determined based on the equipment specifications and the final product requirements; too much or too little material may affect the final molding effect. After the material is placed, the power is connected via the power interface 12, causing the heating wire 13 to start working. The heating wire 13 continuously heats the material inside the outer shell. During the heating process, the heating temperature needs to be closely monitored, as different silver and copper materials may require different heating temperature ranges. Only at the appropriate temperature can the material reach its optimal physical state, facilitating subsequent extrusion molding operations.

[0031] Then, the hydraulic column 10 is continuously pressed down under the drive of the hydraulic device 5. During the downward pressing of the hydraulic column 10, the silver-copper material will continue to move downward under the pressure of the hydraulic column 10 and be separated from it by the diversion cone 15. The shape and angle of the diversion cone 15 have an important influence on the diversion effect of the material. A well-designed diversion cone 15 can make the material be evenly separated, preparing it for subsequent molding operations.

[0032] Finally, under the powerful pressure of the hydraulic column 10, the silver-copper material passes through multiple forming die holes 16 provided on the diversion mold 14. As it passes through these forming die holes 16, the silver-copper material is pressed into the designed shape due to the strong extrusion force.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
