[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figures 1 to 3As shown, one embodiment of this utility model provides a self-lubricating punch press guide rail, including a mounting block 1. The mounting block 1 serves as the mounting base for the entire punch press guide rail, providing stable support for subsequent components. It is firmly fixed at a specific position on the punch press, ensuring the entire guide rail structure remains stable during punch press operation, preventing shaking or displacement. A slide rail 2 is fixedly connected to the front side of the mounting block 1. The slide rail 2 is a major component of the punch press guide rail, providing a track for the sliding of the slider 5. It has a high-precision surface to ensure that the slider 5 can slide smoothly on it, achieving directional movement of the punch press components. A groove 3 is provided inside the slide rail 2, providing sliding space for the slider 5. Its size matches the slider 5, allowing the slider 5 to slide stably without shaking or jamming.

[0032] The slide rail 2 has a limiting groove 4 inside, which limits the range of motion of the slider 5. It works in conjunction with the limiting block 6 to prevent the slider 5 from disengaging from the slide rail 2 during sliding, thus ensuring the stability and safety of the punch press components during operation.

[0033] Reference Figures 1 to 3 As shown, a slider 5 is slidably connected inside the slide rail 3. The slider 5 is a moving part in the punch press guide rail. By sliding on the slide rail 2, it drives other parts of the punch press to move. The slider 5 is externally slidably connected inside the slide rail 2. Its surface is specially treated to reduce friction with the slide rail 2 and improve the smoothness of sliding.

[0034] The limiting block 6 is externally slidably connected to the inside of the limiting groove 4. The limiting block 6 is an important component of the slider 5, and its cooperation with the limiting groove 4 ensures that the slider 5 will not deviate from the track during movement. The size and shape of the limiting block 6 match the limiting groove 4, enabling it to slide stably within the limiting groove 4 while withstanding various forces generated during the operation of the punch press.

[0035] A mounting assembly is fixedly connected to the top of the slider 5 for secure installation. This assembly includes a connecting block 7, a key component connecting the slider 5 to other punch press parts. Its bottom is fixedly connected to the top of the slider 5, providing a reliable connection point for the punch press parts. The connecting block 7 has a connecting hole 8 on its exterior, providing a mounting position for connecting bolts 11 or other connecting parts, allowing the punch press parts to be securely mounted on the connecting block 7 and move together with the slider 5.

[0036] Reference Figure 4 As shown, oil reservoirs 9 are slidably connected to both the left and right sides of the slide rail 2. The oil reservoirs 9 are key components for achieving self-lubrication, storing lubricating oil inside. Their sliding connection with the slide rail 2 allows the oil reservoirs 9 to be adjusted as needed, ensuring that the lubricating oil flows accurately to the parts requiring lubrication.

[0037] The external fixed connection of the oil storage pipe 9 includes a fixing component for installation, which includes a fixing block 10. The fixing block 10 serves to fix the oil storage pipe 9. Its top is fixedly connected to the bottom of the oil storage pipe 9 and is fixedly connected to the slide rail 2 by bolts 11 to ensure that the oil storage pipe 9 will not be displaced during the operation of the punch press.

[0038] The fixing block 10 has an internal threaded connection with a bolt 11, which is an important connecting component between the fixing block 10 and the oil storage pipe 9. Through its threaded connection with the fixing block 10, the bolt 11 securely fixes the oil storage pipe 9 to the slide rail 2, preventing the oil storage pipe 9 from loosening or falling off during the operation of the punch press.

[0039] Multiple baffles 12 are fixedly connected inside the oil reservoir 9. These baffles 12 filter impurities. Fixed inside the oil reservoir 9, they prevent impurities from entering, ensuring the quality of the lubricating oil. The arrangement of the multiple baffles 12 effectively filters impurities of different sizes, improving the cleanliness of the lubricating oil.

[0040] Multiple baffles 12 are externally fixedly connected to filter cotton 13, which further enhances the filtration effect. Fixed to the outside of the baffles 12, the filter cotton 13 filters out minute impurities, preventing them from entering the oil reservoir 9 and affecting the quality of the lubricating oil. The filter cotton 13 is made of a material with good filtration performance and durability, enabling it to continuously perform its filtration function during the operation of the punch press.

[0041] A conical cylinder 14 is fixedly connected to one side of each of the two oil reservoirs 9. The design of the conical cylinder 14 allows the lubricating oil to flow more smoothly to the parts that need lubrication. It is fixed to one side of the oil reservoir 9 and is conical in shape. It can guide the lubricating oil to the friction part between the slider 5 and the slide rail 2, thereby improving the lubrication effect.

[0042] Reference Figures 4 to 5 As shown, a ball bearing 15 is rotatably connected inside the conical cylinder 14. The ball bearing 15 rolls between the slider 5 and the slide rail 2, reducing friction while also carrying lubricating oil from the oil reservoir 9 to the friction parts, achieving the effect of automatically adding lubricating oil. The surface of the ball bearing 15 is smooth, allowing it to rotate freely inside the conical cylinder 14. When it contacts the slider 5 and the slide rail 2, it can evenly apply lubricating oil to the friction parts, reducing the coefficient of friction and improving the service life of the punch press guide rail.

[0043] The outer surface of the ball bearing 15 contacts the outer surface of the spring 16. The spring 16 can apply a certain pressure to the ball bearing 15 to ensure that the ball bearing 15 is always in contact with the slide rail 2 and the slider 5, thereby improving the lubrication effect. The elasticity of the spring 16 can automatically adjust the pressure on the ball bearing 15 according to different conditions during the operation of the punch press, ensuring that the ball bearing 15 can effectively perform its lubrication function under different working conditions.

[0044] The top of the oil reservoir 9 is threadedly connected to an internally threaded cylinder 17, which mates with the top cover 18 to seal the oil reservoir 9. The threaded connection to the top of the oil reservoir 9 ensures a tight seal and prevents lubricating oil leakage.

[0045] A top cover 18 is fixedly connected to the top of the internally threaded cylinder 17. The top cover 18 is one of the sealing components of the oil reservoir 9. It is fixed to the top of the internally threaded cylinder 17 and together with the internally threaded cylinder 17, forms a double seal to ensure the sealing performance of the oil reservoir 9.

[0046] A sleeve 19 is fixedly connected inside the top cover 18, providing installation space for the second spring 20 and the cylindrical sleeve 21. It is fixed inside the top cover 18, serving to support and protect the second spring 20 and the cylindrical sleeve 21.

[0047] A second spring 20 is installed inside the sleeve 19. The second spring 20 provides pressure to the cylindrical sleeve 21 to enhance the sealing effect. One side is fixedly connected to the inside of the sleeve 19, and the other side is connected to the cylindrical sleeve 21. It can automatically adjust the pressure on the cylindrical sleeve 21 according to the pressure change in the oil reservoir 9 to ensure that the sealing ring 22 is always in tight contact with the oil reservoir 9.

[0048] The other side of the second spring 20 is fixedly connected to the inside of the cylindrical sleeve 21. Under the action of the second spring 20, the cylindrical sleeve 21, together with the sealing ring 22, forms a sealing structure. Its interior is connected to the second spring 20, and its exterior is fixedly connected to the sealing ring 22. Under the pressure of the second spring 20, the sealing ring 22 can be pressed tightly into the inside of the oil reservoir 9, thereby improving the sealing effect.

[0049] A cylindrical sleeve 21 is slidably connected inside the sleeve 19. The cylindrical sleeve 21 can slide within the sleeve 19 to adapt to different sealing requirements. Together with the sealing ring 22, it seals the oil reservoir 9 under the action of the spring 20.

[0050] A sealing ring 22 is fixedly connected to the bottom of the cylindrical sleeve 21, which ensures the sealing of the connection and prevents lubricating oil leakage. Its external sliding connection is inside the oil reservoir 9. It is made of rubber, which has good elasticity and sealing performance, and can fit tightly against the inner wall of the oil reservoir 9 to prevent lubricating oil leakage.

[0051] Working principle: During the operation of the punch press, the mounting block 1 serves to fix the entire guide rail structure. The slide rail 2 and the slider 5 cooperate with each other. The slider 5 slides on the slide rail 2 through the slide groove 3, realizing the directional movement of the punch press components. The cooperation of the limiting groove 4 and the limiting block 6 can prevent the slider 5 from disengaging from the slide rail 2 during sliding, ensuring the stability of the movement.

[0052] Connecting block 7 is used to connect slider 5 to other punch press components, and connecting hole 8 provides the mounting position for the connection. Oil reservoir 9 is a key component for achieving self-lubrication, and it stores lubricating oil inside. Fixing block 10 is fixed to slide rail 2 by bolts 11 to ensure the stability of oil reservoir 9.

[0053] When slider 5 slides on slide rail 2, stop bar 12 and filter cotton 13 filter impurities, preventing them from entering oil reservoir 9 and affecting the quality of lubricating oil. The conical cylinder 14 design allows lubricating oil to flow more smoothly to the parts that need lubrication. Ball bearings 15 roll between slider 5 and slide rail 2, reducing friction while also carrying lubricating oil from oil reservoir 9 to the friction parts, achieving automatic lubrication. Spring 16 applies a certain pressure to ball bearings 15, ensuring that ball bearings 15 are always in contact with slide rail 2 and slider 5, improving the lubrication effect.

[0054] The internally threaded sleeve 17 mates with the top cover 18 to seal the oil reservoir 9. The combination of the sleeve 19, spring 20, and cylindrical sleeve 21 further enhances the sealing effect. The sealing ring 22 ensures the tightness of the connection and prevents lubricating oil leakage.

[0055] It enables automatic addition of lubricating oil between slide rail 2 and slider 5, and effectively seals oil reservoir 9, thereby improving the service life and working efficiency of punch press guide rails.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
