Description

Technical Field

[0001] The utility model relates to the field of press brakes, in particular to an aluminum press brake for processing wall-mounted guide rails of medical institutions. Background Art

[0002] The aluminum press brake for processing wall-mounted guide rails in medical institutions is a type of equipment specially used in the field of medical equipment manufacturing. It is usually used to process aluminum guide rails to make components in medical equipment that require guide rails, such as medical beds, wheelchairs, operating tables, etc. This type of press brake usually has special designs suitable for medical environments, such as compact wall-mounted design, easy-to-clean surface, and safety features that meet medical standards.

[0003] After searching, the existing Chinese patent announcement number is: CN219899781U, a press bending machine for processing aluminum materials of automobile sunroof guide rails, which belongs to the field of aluminum processing technology. The middle part of the front end of the processing platform is provided with a hot air outlet plate located between the two limiting blocks, and the hot air outlet plate is connected to the air outlet end of the hot air fan on the upper surface of the processing platform. The air outlet cover on the inner side of the hot air outlet plate corresponds to the middle air outlet of the two limiting blocks. The hot air generated by the hot air fan running on the hot air outlet plate is output to the guide rail aluminum material through the air outlet cover, and the bent position of the guide rail aluminum material is heated, so that when the guide rail aluminum material is pressed by the pressing block to produce a bending effect, the ductility of the guide rail aluminum material is further increased by the output of hot air, ensuring that when the guide rail aluminum material is press-bent, the extension of the bent outer side of the guide rail aluminum material will not cause fracture problems, while improving the processing efficiency of the guide rail aluminum material and ensuring the processing quality of the guide rail aluminum material.

[0004] In the specific implementation method of the above patent, the guide rail aluminum material to be bent is supported by two limiting blocks, and the upper pressure plate is moved downward in coordination with the guide rail aluminum material limiting rubber block on the bottom surface of the upper pressure plate is embedded in the limiting groove on the upper part of the limiting block, and the guide rail aluminum material is tightly fixed in the limiting groove. The hydraulic cylinder moves in the direction of the guide rail aluminum material through the pressing block, and the pressing block pushes the guide rail aluminum material toward the position of the hot air outlet plate, generating a bending force on the guide rail aluminum material. When the guide rail aluminum material is limited by the limiting block, the hot air outlet plate pushes the hot air generated by the hot air blower to the hot air outlet plate through the outlet hood. The guide rail aluminum material is output and the bent position of the guide rail aluminum material is heated. In this patent, the ductility of the guide rail aluminum material is further increased by outputting hot air while the guide rail aluminum material is being bent, ensuring that the extension of the outer side of the guide rail aluminum material when it is bent will not cause breakage problems, thereby ensuring the processing quality of the guide rail aluminum material. However, this patent does not explain how to load and unload the guide rail aluminum material when it is necessary to bend the guide rail aluminum material. Workers need to manually load and unload the guide rail aluminum material, which increases the labor intensity of workers and also has certain safety hazards. Utility Model Content

[0026] Reference Figure 1 - Figure 3 and Figure 4 The utility model provides an embodiment: an aluminum press bending machine for wall-mounted guide rail processing in medical institutions, including a lower press 1 and a lower die base 3. A lower pressing die 2 is installed inside the lower press 1, and a pushing block 4 is slidably connected to the interior of the lower die base 3. The pushing block 4 is designed to be driven by the pulling rod 5 when the lower pressing die 2 is raised to load the guide rail. The top of the pushing block 4 is rotatably connected to the pulling rod 5, and the pulling rod 5 is designed to connect the pushing block 4 and the lower pressing die 2. The bottom end of the lower press 1 is fixedly connected with a reset spring 6. The reset spring 6 is designed to push the placement plate 8, thereby pushing the blanking plate 9 to blank the guide rail after the bending is completed.

[0027] The inner bottom end of the down-presser 1 is fixedly connected to a limiting assembly, and the outer side of the limiting assembly is slidably connected to a placement plate 8. The placement plate 8 is designed to cooperate with the blanking plate 9 to blank the guide rail that has been bent. The top of the placement plate 8 is fixedly connected to two blanking plates 9, and the rear end of the down-pressing mold 2 is fixedly connected to a mounting plate 10. The mounting plate 10 is designed to cooperate with the down-pressing rod 11. When the down-pressing mold 2 is pressed down, the placement plate 8 is pressed down, thereby pressing the blanking plate 9 into the interior of the lower mold base 3 without obstructing the guide rail that needs to be bent.

[0028] The internal thread connection of the mounting plate 10 is connected to the lower pressure rod 11, and the interior of the lower mold base 3 is provided with a sliding groove 12. The design of the sliding groove 12 is to facilitate the sliding of the push block 2 13. The internal sliding connection of the sliding groove 12 is connected to the push block 2 13. The design of the push block 2 13 is to press down the placement plate 8 and the blanking plate 9 through the lower pressure plate 14 under the push of the push block 1 4, so that the blanking plate 9 will not hinder the guide rail from being sent to the bottom of the lower pressure mold 2. The internal rotation of the push block 2 13 is connected to the lower pressure plate 14. The lower pressure plate 14 is designed to connect the push block 2 13 and the placement plate 8.

[0030] The bottom end of the lower pressure rod 11 contacts the top of the placement plate 8. The lower pressure rod 11 is designed to cooperate with the mounting plate 10. When the lower pressure mold 2 is pressed down, the placement plate 8 is pressed down, thereby pressing the blanking plate 9 into the interior of the lower die base 3 without hindering the guide rail that needs to be bent. The outer bottom end of the lower pressure plate 14 is rotatably connected to the left inner side of the placement plate 8. The lower pressure plate 14 is designed to connect the push block 2 13 and the placement plate 8. The limit assembly includes four limit rods 7. The bottom ends of the four limit rods 7 are fixedly connected to the inner bottom end of the lower press 1. The limit rod 7 is designed to limit the placement plate 8.

[0031] like Figure 1 and Figure 5 As shown, the feeding assembly includes a material storage seat 15, a limiting rod 16, a motor 17, a threaded rod 18, a sliding groove 19 and a pushing block 20. The front side of the material storage seat 15 is fixedly connected to the rear end of the lower die seat 3. The material storage seat 15 is designed to conveniently accommodate the guide rail to be fed into the lower die seat 3. The limiting rod 16 is arranged on the right side of the material storage seat 15. The limiting rod 16 is designed to limit the pushing block 20. The motor 17 is installed on the left side of the material storage seat 15. The motor 17 is designed to drive the threaded rod 18, thereby driving the pushing block 20.

[0032] The rear end of the threaded rod 18 is fixedly connected to the driving end of the motor 17. The threaded rod 18 is designed to rotate under the drive of the motor 17 and drive the pushing block 20 to send the guide rail stored in the material storage seat 15 into the interior of the lower mold base 3. The sliding groove 19 is opened on the left side of the material storage seat 15. The outer side of the pushing block 20 is slidably connected to the interior of the material storage seat 15. The right side of the material storage seat 15 contacts the left side of the lower presser 1. The material storage seat 15 is designed to conveniently accommodate the guide rail to be fed into the lower mold base 3. The outer side of the limit rod 16 is slidably connected to the interior of the pushing block 20. The limit rod 16 is designed to limit the pushing block 20.

[0033] The four corners of the bottom end of the material storage seat 15 are fixedly connected to support legs 21. The support legs 21 are designed to support the material storage seat 15. The outer side of the threaded rod 18 is rotatably connected to the inside of the pushing block 20, and the outer side of the pushing block 20 is slidably connected to the inside of the sliding groove 19. The threaded rod 18 is designed to rotate under the drive of the motor 17 and drive the pushing block 20 to send the guide rail stored in the material storage seat 15 into the interior of the lower mold base 3.

[0034] Working principle: when the lower press 1 presses down the lower pressing die 2, the lower pressing die 2 presses down the guide rail placed on the right side of the lower die base 3, thereby completing the bending work. When the lower pressing die 2 rises and is lifted, the lower pressing rod 11 will not squeeze the setting plate 8, and the setting plate 8 will also lift the blanking plate 9 under the push of the return spring 6, and blank the guide rail to be bent on the right side of the lower die base 3. And when the lower pressing die 2 is lifted, the pushing block 1 4 also sends the guide rail to be bent placed on the left side of the lower die base 3 to the right side of the lower die base 3 under the pull of the pulling rod 5. During this period, the sliding groove 12 will also push the pushing block 2 13, thereby pushing the lower pressing plate 14 to press the setting plate 8, so that the blanking plate 9 is retracted into the interior of the lower die base 3 and will not block the guide rail. At this time, the lower pressing die 2 will press down again to bend the guide rail, and when the pushing block 1 4 returns to its original position, the blanking plate 9 is about to touch the guide rail to be bent under the push of the return spring 6. When the guide rail is being loaded, the setting plate 8 and the blanking plate 9 are pressed down again by the lower pressure rod 11, thereby completing the bending work of the guide rail. When the lower pressure mold 2 is lifted again, the lower pressure rod 11 will no longer press the setting plate 8, and the setting plate 8 will cooperate with the blanking plate 9, and under the push of the return spring 6, the bent guide rail is unloaded. By using the loading and unloading device, the guide rail is automatically loaded and unloaded, and there is no need for workers to manually load and unload the guide rail aluminum material, which reduces the labor intensity of workers and eliminates the safety hazards of manual loading. The storage seat 15 stores the guide rails that need to be pushed into the left side of the interior of the lower die seat 3. By starting the motor 17, the motor 17 drives the threaded rod 18 to rotate, thereby driving the pushing block 20 to feed the guide rails into the left side of the interior of the lower die seat 3 one by one. By using the feeding device to continuously feed the guide rails that need to be loaded into the left side of the interior of the lower die seat 3, the entire bending process can be accelerated, the working efficiency of the bending work can be improved, and the production benefits can be expanded.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
