[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a frame-type extrusion body 1 for a railway turnout switch machine. Figure 1 A frame extruded body 1 for railway turnout switch includes a frame extruded body 1 of a rectangular structure formed by forging and machining, a circular through hole 11 and a U-shaped through slot 12 are arranged on the top of the frame extruded body 1, two rectangular through holes 13 are symmetrically arranged on the side of the frame extruded body 1, a square boss 2 is arranged on the top of the frame extruded body 1 corresponding to the circular through hole 11, the square boss 2 is provided with a thread and a through hole 14, and the side is also provided with two horizontal through slots 15 according to the design position. This design reduces the types of parts, simplifies the assembly process, and improves the overall reliability and maintenance convenience of the switch machine.

[0029] Specifically, the overall shape of the frame-type extruded body 1 is forged and formed into a final state by machining. Forging can ensure the density and strength of the material, and machining can accurately control the size and surface quality. The frame-type extruded body 1 is a rectangular structure, and the size and proportion can be adjusted according to actual needs to adapt to different application scenarios. For example, the height of the frame-type extruded body 1 can be selected between 10mm and 20mm, the width can be selected between 50mm and 100mm, and the length can be flexibly designed according to actual application needs.

[0030] The circular through hole 11 and the rectangular through hole 13 on the frame-type extrusion body 1 are used to connect with other parts. For example, the circular through hole 11 can be used to install fasteners, such as screws or pins, and the rectangular through hole 13 can be used to install guides or other functional parts. Specifically, the circular through hole 11 can adopt a standard threaded hole of M6 or M8 specification to meet common installation requirements. The design of these through holes 11 can not only improve the reliability of the connection, but also facilitate disassembly and replacement.

[0031] The two rectangular through holes 13 on the frame-type extrusion body 1 are used to install the locking roller. The size of the rectangular through hole 13 can be selected to be 15mm x 30mm to ensure that the locking roller can enter and exit smoothly. The edges of the rectangular through hole 13 can be chamfered to reduce friction and wear. In addition, reinforcing ribs can be added around the rectangular through hole 13 to enhance the rigidity and stability of the local structure.

[0032] The upper plane is processed with a U-shaped through-slot 12 structure, and this U-shaped through-slot 12 is used to accommodate the action plate. The opening width of the U-shaped through-slot 12 can be selected to be 20 mm, and the depth can be selected to be 10 mm, so that the action plate can be smoothly inserted and fixed. Guide rails can be set on both sides of the U-shaped through-slot 12 to guide the action plate to be accurately in place. A rubber gasket can be set at the bottom of the U-shaped through-slot 12 to absorb vibration and noise and improve the stability of the system.

[0033] A square boss 2 is provided on the upper plane, and has a thread and a through hole 14 structure. The height of the square boss 2 can be selected to be 5 mm, and the side length can be selected to be 20 mm to provide sufficient support area. A plurality of threaded holes, such as four M6 threaded holes, can be provided on the square boss 2 for fixing other components. The position of the threaded holes can be adjusted according to actual needs to ensure the best fixing effect. In addition, an anti-slip texture can be provided on the top of the square boss 2 to prevent the components from loosening.

[0034] The two horizontal through slots 15 on the side are used to install auxiliary positioning devices. The size of the horizontal through slot 15 can be selected to be 15mm x 30mm to accommodate common positioning devices. The inner wall of the horizontal through slot 15 can be provided with a lubricating coating to reduce friction and extend the service life. In addition, baffles can be provided at both ends of the horizontal through slot 15 to prevent the positioning device from accidentally falling off.

[0035] A set of disc spring components is added inside the frame-type extrusion body 1 to provide elastic support. This design can further improve the buffering capacity and impact resistance of the system and is suitable for more severe working environments.

[0036] Specifically, a set of disc spring assemblies is provided inside the frame-type extrusion body 1, and the disc spring assembly is composed of a plurality of disc springs stacked. The diameter of each disc spring can be selected to be 20 mm, the thickness can be selected to be 2 mm, and the maximum compression amount can be selected to be 10 mm. The disc spring assembly can be fixed inside the frame-type extrusion body 1 by welding or snapping, etc., to ensure that it can respond quickly and return to its original state when subjected to external force. The selection of disc spring assemblies can be adjusted according to actual working conditions. For example, if the switch machine is often subjected to large impact loads, a disc spring with a larger diameter and higher elasticity can be selected; if the working environment of the switch machine is relatively mild, a disc spring with a smaller diameter and lower elasticity can be selected.

[0037] By introducing the disc spring assembly, the frame-type extruded body 1 has added buffering and shock-absorbing functions while maintaining its original advantages. When the switch machine is subjected to external impact or vibration, the disc spring assembly can quickly absorb energy and reduce the impact on the system. This design is particularly suitable for use in harsh environments such as high-speed railways and heavy-load railways, and can significantly improve the reliability and life of the switch machine. At the same time, the addition of the disc spring assembly does not significantly increase the volume and weight of the frame-type extruded body 1, and the lightweight and compact design concept is still maintained. In general, this improvement not only improves the overall performance of the system, but also brings more convenience and protection to users.

[0038] The overall thickness of the frame-type extruded body 1 does not exceed 15 mm, ensuring sufficient rigidity and lightweight design. This design can better meet the requirements of modern railway transportation for lightweight and high performance.

[0039] Specifically, the overall thickness of the frame-type extruded body 1 is set to 15mm, which is the optimal value based on mechanical analysis and actual testing. At this thickness, the frame-type extruded body 1 can minimize its own weight while ensuring sufficient rigidity. For example, the main part of the frame-type extruded body 1 can be made of high-strength alloy steel with a density of about 7.8g / cm³ and a yield strength of more than 800MPa, which can meet the strength requirements and achieve lightweight design. In addition, different thickness designs can be used for various parts of the frame-type extruded body 1. For example, the key stress-bearing area can be appropriately thickened, and the non-critical area can be appropriately thinned to balance the relationship between rigidity and weight.

[0040] By optimizing the overall thickness of the frame-type extruded body 1, the dual goals of lightweight and high performance are achieved. The lightweight design is not only conducive to reducing the deadweight of the entire switch machine, but also reduces the pressure on the track and other infrastructure, and improves the overall efficiency of the system. At the same time, the reasonable thickness distribution ensures that the frame-type extruded body 1 can still maintain stable performance when subjected to large loads, and will not cause structural failure due to being too thin. This design has shown excellent performance in practical applications, especially in the fields of high-speed railways and urban rail transit, which can significantly improve the system's operating quality and passengers' sense of safety.

[0041] The surface of the frame-type extrusion body 1 is heat-treated to improve wear resistance and impact resistance. This design can extend the service life of the product and reduce the maintenance frequency.

[0042] Specifically, the surface of the frame-type extruded body 1 is treated with carburizing and quenching, which is a commonly used metal surface strengthening technology. Carburizing and quenching can make the surface layer obtain high hardness and good wear resistance, while retaining good toughness of the core. The carburizing temperature is generally between 900°C and 950°C, and the holding time is 1 hour to 2 hours, followed by oil cooling or water cooling quenching. The surface hardness after treatment can reach HRC58 to 62, and the core hardness can be maintained at about HRC30. In addition, in order to further improve the corrosion resistance, a layer of anti-corrosion coating, such as epoxy resin or polyurethane coating, can be coated on the surface.

[0043] Through heat treatment and surface protection measures, the surface of the frame extruded body 1 has obtained higher hardness and better wear resistance, so that it can resist wear and impact for a long time. This is especially important for switch machines that are in outdoor environments for a long time. It can significantly extend the service life of the product and reduce the failure rate caused by surface damage. At the same time, good corrosion resistance also enables the frame extruded body 1 to maintain excellent performance in humid or dusty environments, improving the overall reliability of the system. In short, this improvement not only improves the physical properties of the frame extruded body 1, but also brings greater convenience to users' daily maintenance.

[0044] The implementation principle of a frame-type extruded body 1 for a railway turnout switch machine in the embodiment of the present application is as follows: by integrating multiple functions into one frame-type extruded body 1, a highly integrated and modular design concept is realized. The overall design of the frame-type extruded body 1 is simple and compact, which reduces the types and quantities of parts, reduces the complexity of the processing technology and the difficulty of assembly. At the same time, the design of various through holes 11, square bosses 2 and U-shaped through slots 12 not only meets the basic functional requirements, but also enhances the strength and stability of the structure, and improves the reliability and durability of the system. This design performs well in practical applications, especially during on-site maintenance and replacement, which greatly shortens the maintenance time, reduces maintenance costs, and improves work efficiency.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
