Description

Technical Field

[0001] This utility model relates to the field of axial flow pump production technology, specifically to an impeller forming device for axial flow pump production. Background Technology

[0002] An axial flow pump is a type of pump that uses the blades of a rotating impeller to exert force on a liquid, thus transporting the liquid along its axis. During the operation of an axial flow pump, an impeller is used to convert the mechanical energy of the prime mover into the pressure and kinetic energy of the fluid, ensuring the normal operation of the pump.

[0003] In the production process of axial flow pump impellers, molten metal needs to be injected into a mold cavity for cooling and forming. However, existing axial flow pump impeller production processes rely on a single mold, reducing impeller forming efficiency and making it inconvenient to ensure that the formed impellers are dropped into a batch on a worktable for inspection and processing. Therefore, this paper proposes an impeller forming device for axial flow pump production to solve the above problems. Utility Model Content

A shelf is provided on the upper surface of the operating table behind the turntable, and a soft rubber pad is provided on the shelf.

[0008] Preferably, the turntable, under the action of the first motor, forms a rotating structure with the operating table through the output shaft.

[0009] Preferably, the nozzle, under the action of the first electric push rod, forms a vertical lifting structure with the operating table through the first telescopic arm.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an impeller forming device for axial flow pump production, including an operating table 1, a first motor 2 inside the operating table 1, and an output shaft above the first motor 2. A turntable 3 is provided at the upper end of the output shaft, and multiple sets of sliders are provided on the lower end face of the turntable 3. The sliders are respectively inserted into the operating table 1. Multiple sets of lower molds 7 are provided on the upper end face of the turntable 3, and upper molds 8 are correspondingly provided above the lower molds 7.

[0020] Furthermore, under the action of the first motor 2, the turntable 3 forms a rotating structure with the operating table 1 through the output shaft, thereby ensuring that multiple sets of molds can be rotated and replaced under the action of the first motor 2, thus ensuring that the device can continuously cast and mold the impeller.

[0021] A first electric push rod 9 is provided on one side of the turntable 3 on the operating table 1, and a first telescopic arm 10 is provided above the first electric push rod 9. A connecting rod is provided at the upper end of the first telescopic arm 10, and the other end of the connecting rod is connected to the nozzle 11. The nozzle 11 is provided with a feed pipe at the upper end, and the nozzle 11 is inserted into the upper mold 8.

[0022] Furthermore, under the action of the first electric push rod 9, the nozzle 11 forms a vertical lifting structure with the operating table 1 through the first telescopic arm 10, so that the impeller can be cast normally without affecting the mold rotation process through the liftable nozzle 11.

[0023] The operating table 1 has a support frame 4 on its upper surface, and a second motor 5 is provided inside the support frame 4. The second motor 5 has an output shaft below it, and a fixed frame 6 is provided at the lower end of the output shaft. The upper surface of the fixed frame 6 has sliders at both ends, and the sliders are inserted into the support frame 4. The fixed frame 6 has multiple sets of second electric push rods 12 inside it, and a second telescopic arm 13 is provided below the second electric push rod 12. The lower end of the second telescopic arm 13 is connected to the upper mold 8.

[0024] Furthermore, the fixed frame 6 forms a rotating structure with the support frame 4 through the output shaft under the action of the second motor 5, and the upper mold 8 forms a vertical lifting structure with the lower mold 7 through the second telescopic arm 13 under the action of the second electric push rod 12. Thus, under the action of the second motor 5, the upper mold 8 and the lower mold 7 can be rotated synchronously to change positions, and under the action of the second electric push rod 12, the impeller after molding can be demolded normally.

[0025] On one side of the lower mold 7, multiple sets of fixing boxes are provided on the turntable 3, and a servo motor 14 is provided inside the fixing box. One end of the output shaft of the servo motor 14 is connected to the rotating shaft 15 through a coupling, and the outer wall of the rotating shaft 15 is connected to the lower mold 7 through a connecting rod. A shelf 16 is provided on the upper surface of the operating table 1 behind the turntable 3, and a soft rubber pad is provided on the shelf 16. It should be noted that all electrical equipment in this device is connected to the power supply equipment through a power cord, and its working status is controlled by a controller to ensure that the device can operate normally.

[0026] Furthermore, the lower mold 7, under the action of the servo motor 14, forms a rotating structure with the shelf 16 via the rotating shaft 15. Thus, the flip-out lower mold 7 ensures that the formed impeller can be automatically unloaded, thereby increasing the impeller forming efficiency while ensuring the convenience of the forming process.

[0027] Working Principle: In the impeller forming device using an axial flow pump, the second electric push rod 12 drives the second telescopic arm 13 to descend, moving the upper mold 8 onto the lower mold 7 for alignment and assembly. After assembly, the first electric push rod 9 is activated, driving the nozzle 11 down into the upper mold 8 via the first telescopic arm 10, allowing molten metal to be injected into the mold cavity for forming. After one mold is filled, the first motor 2 and the second motor 5 are simultaneously activated. The first motor 2 drives the turntable 3 to rotate via its output shaft, while the second motor 5 drives the fixed frame 6 to rotate via its output shaft, ensuring synchronous rotation and replacement of the two molds for further processing via the nozzle 11. Another set of molds is used for material injection, thereby ensuring that the device can continuously form impellers and increase the efficiency of impeller forming. After the molten metal cools and forms in the mold, the corresponding second electric push rod 12 can be activated, which drives the upper mold 8 to rise through the second telescopic arm 13. Then, the servo motor 14 can be activated. The output shaft of the servo motor 14 drives the rotating shaft 15 to rotate through the coupling, so that the lower mold 7 can be flipped through the rotating shaft 15. This allows the formed impeller to be automatically unloaded onto the shelf 16, so that the formed impeller can be inspected and processed by the staff. This increases the convenience of the impeller forming process and effectively ensures the forming effect of the impeller. This is the usage process of the impeller forming device for axial flow pump production.

[0028] Although the present invention 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 invention should be included within the protection scope of the present invention.
