[0002] The rough machining equipment for alloy propeller curved surfaces is mainly used to rough machine alloy plates into three-dimensional twisted curved surface structures. This equipment is mainly used in the shipbuilding industry, aviation field and new energy industry, and is the core equipment in the manufacturing process of key power components in these fields. The structure of rough machining equipment for alloy propeller curved surfaces typically consists of a multi-axis linkage CNC system, special cutting tools, a high-precision workpiece clamping platform, and a cooling and lubrication system. Its main function is to perform efficient rough machining on propeller alloy blanks, quickly remove excess material from the surface of the blanks, and at the same time machine the basic shape according to the preset propeller curved surface contour, laying a stable surface accuracy foundation for subsequent precision grinding, polishing and other finishing processes. Currently available rough machining equipment for alloy propeller surfaces requires a significant amount of time for milling when processing alloy steel plates, impacting work efficiency. Since only the approximate outline of the alloy propeller surface needs to be formed before fine machining, a rough machining equipment for alloy propeller surfaces is proposed to address this issue. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a rough machining equipment for the curved surface of alloy propellers, which aims to improve the problem of the large amount of time required when machining alloy steel plates.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a rough machining device for curved surfaces of alloy propellers, comprising a support frame 1, four legs fixedly connected inside the support frame 1, a support frame 2, a support frame 3, and a support frame 4 fixedly connected outside the support legs, four connecting rods 1 fixedly connected inside the support frame 4, a hydraulic base 1 fixedly connected to one end of each connecting rod 1 away from the support frame 4, a hydraulic push rod 1 fixedly connected inside the hydraulic base 1, a die-casting mold 1 fixedly connected to the output end of the hydraulic push rod 1, and a die-casting mold 1 externally connected to the die-casting mold 1. Four sliding rods are fixedly connected. A limiting plate is fixedly connected to the end of each sliding rod away from the die-casting mold. Four connecting rods are fixedly connected to the inner side of the bracket. A hydraulic base is fixedly connected to the end of each connecting rod away from the bracket. A hydraulic push rod is fixedly connected inside the hydraulic base. The output end of the hydraulic push rod is fixedly connected to the die-casting mold. Four sliding rods are fixedly connected to the outside of the die-casting mold. A limiting plate is fixedly connected to the end of each sliding rod away from the die-casting mold. A mold groove is opened at the bottom of the die-casting mold and a mold groove is opened at the top of the die-casting mold.

[0005] As a further description of the above technical solution: The bracket 2 has two outer shells 2 fixedly connected inside, and the bracket 3 has two outer shells 1 fixedly connected inside. Both outer shells 1 and 2 have sliders slidably connected inside. Each slider has a transmission component fixedly connected to its opposite side. The transmission component has a roller rotatably connected to its outside. The slider has two threaded rods threadedly connected inside.

[0011] This utility model has the following beneficial effects: 1. In this utility model, efficient roughing is achieved through the working principle of die casting. The transmission component drives the rollers to stably transport the blank to the die casting mold. Then, the hydraulic push rod drives the two die casting molds to approach each other. The mold groove on the mold allows the blank to quickly form the approximate curved surface outline of the alloy propeller. There is no need to rely on the traditional time-consuming milling process, which greatly shortens the roughing time.

[0012] 2. In this utility model, the gap between the rollers can be flexibly changed by adjusting the threaded rod, which can adapt to alloy blanks of different thicknesses. When encountering alloy blanks of different thicknesses, only the handle needs to be turned, which increases the versatility of the equipment and indirectly improves work efficiency.

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.

[0016] Reference Figures 1-4 This utility model provides an embodiment of a rough machining equipment for curved surfaces of alloy propellers, comprising a support frame 1. Four legs 5 for enhancing the overall stability of the equipment are fixedly connected inside the support frame 1. Support frames 2, 3, and 4 are fixedly connected to the outside of the legs 5. Four connecting rods 6 are fixedly connected to the inside of the support frame 4. A hydraulic base 7 is fixedly connected to the end of each connecting rod 6 away from the support frame 4. A hydraulic push rod 8 is fixedly connected inside the hydraulic base 7. A die-casting mold 9 is fixedly connected to the output end of the hydraulic push rod 8. Four guide rods 11 are fixedly connected to the outside of the die-casting mold 9. A limit plate 12 is fixedly connected to the end of each guide rod 11 away from the die-casting mold 9. The bracket 1 has four symmetrically distributed connecting rods 13 fixedly connected to its inner side. The ends of the four connecting rods 13 away from the bracket 1 are fixedly connected to a hydraulic base 14 that cooperates with the hydraulic base 7. The hydraulic base 14 has a hydraulic push rod 15 fixedly connected inside. The output end of the hydraulic push rod 15 is fixedly connected to a die casting mold 16 that corresponds to and matches the die casting mold 9. The die casting mold 16 has four auxiliary guide slide rods 18 fixedly connected to its outer side. The end of the slide rod 18 away from the die casting mold 16 is fixedly connected to a limit plate 19. The bottom of the die casting mold 9 is provided with a model groove 10 that matches the profile of the propeller blank. The top of the die casting mold 16 is provided with a model groove 17 that corresponds to and fits the model groove 10.

[0017] Reference Figures 1-4 The bracket 2 has two outer shells 21 fixedly connected inside. The bracket 3 has two outer shells 20 corresponding to the positions of the outer shells 21 fixedly connected inside. Both the outer shells 20 and 21 have sliders 22 slidably connected inside. The opposite side of each slider 22 is fixedly connected to a transmission assembly 23. The transmission assembly 23 is externally rotatably connected to a roller 24 for conveying the propeller blank. The slider 22 has two threaded rods 25 threadedly connected inside. The end of the threaded rod 25 away from the slider 22 is fixedly connected to a handle 26 for easy rotation of the threaded rod 25 by the operator.

[0018] Reference Figures 3-4 The transmission assembly 23 contains a power device that provides power for the rotation of the roller 24, so as to ensure that the roller 24 can stably transmit power to the workpiece and guarantee the power transmission requirements during the processing of the equipment.

[0019] Reference Figures 1-2 Limiting plate 12 abuts against the top of hydraulic base 7, which can limit the maximum sliding stroke of slide rod 11 when hydraulic push rod 8 pushes die casting mold 9 to move, so as to prevent slide rod 11 from dislodging from hydraulic base 7 and affecting equipment operation; limiting plate 2 19 abuts against the bottom of hydraulic base 2 14 and limits the sliding stroke of slide rod 2 18, ensuring the stability of die casting mold 2 16 during movement.

[0020] Reference Figures 1-2 Slide rod 11 is slidably connected inside hydraulic base 7 to guide the up and down movement of die casting mold 9. Slide rod 2 18 is slidably connected inside hydraulic base 2 14 to guide the movement of die casting mold 2 16, ensuring the accuracy of die casting mold 2 16 when it docks with die casting mold 9.

[0021] Reference Figures 3-4 The four threaded rods 25 at the top are rotatably connected to the inside of the outer casing 20. When the handle 26 is turned, the slider 22 can be driven to slide along the inner wall of the outer casing 20. The four threaded rods 25 at the bottom are rotatably connected to the inside of the outer casing 21 to adjust the position of the lower slider 22, ensuring the synchronicity and stability of the adjustment of the upper and lower sliders 22. When encountering blanks of different thicknesses, the gap between the rollers 24 can be finely adjusted.

[0022] Reference Figures 3-4 A handle 26 is fixedly connected to the end of the threaded rod 25 away from the slider 22. The handle 26 allows for manual adjustment of the rotation of the threaded rod 25 without the need for additional tools, thus improving the ease of operation.

[0023] Reference Figures 3-4 The two upper sliders 22 abut against the inner wall of the outer shell 20, which can limit the lateral displacement of the sliders 22 within the outer shell 20, ensuring that the sliders 22 slide only along the length of the outer shell 20 and avoid shaking; the two lower sliders 22 abut against the inner wall of the outer shell 21, which also plays the role of limiting lateral displacement, ensuring the stability of the sliders 22 when driving the transmission component 23 and the roller 24, thereby ensuring the accuracy of the auxiliary operation of the propeller blank.

[0024] Working principle: Rotating handle 26 drives threaded rod 25 to rotate inside outer shell 20 and outer shell 21 respectively, causing slider 22 to slide along the inner walls of outer shell 20 and outer shell 21. This, in turn, adjusts the gap between transmission assembly 23 and roller 24 to match the thickness of the propeller blank to be processed. Then, the power device inside transmission assembly 23 starts, causing roller 24 to rotate stably and transport the propeller blank between die-casting mold 9 and die-casting mold 16. Subsequently, hydraulic push rod 8 and hydraulic push rod 15 start synchronously. Hydraulic push rod 8 pushes die-casting mold 9 downward, and hydraulic push rod 15 pushes die-casting mold 16 upward. Model groove 10 and model groove 17 correspond and fit, die-casting the propeller blank. Throughout the entire processing, the overall stability of the equipment is ensured by bracket 1 and the four internally fixed support legs 5, as well as the externally connected brackets 2, 3, and 4, completing the rough surface machining process of the propeller blank.

[0025] 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.
