[0002] At present, in the process of flower-shaped impeller production, flower-shaped impeller automatic forming machines are mostly used for automatic impeller forming production, which improves the production efficiency of flower-shaped impellers to a certain extent. However, the swing arm mechanism of the current flower-shaped impeller automatic forming machine adopts a linear swing arm, which cannot unload the formed impeller while loading the lower mold. The impeller needs to be set up separately for unloading operations, which leads to a large overall size of the forming machine and low work efficiency; in addition, the existing flower-shaped impeller automatic forming machine places the lower mold on the rotating platform before performing the feeding operation, which leads to the feeding efficiency being affected due to the loose fixation of the lower mold and the lower positioning tooling during the feeding process.

[0036] The shaping mechanism 7 comprises a base 701 fixed on the working platform 1, a fourth cylinder 702 is arranged on the base 701, a slider 703 is connected to the output shaft end of the fourth cylinder 702, and a shaping disc 704 is arranged on the slider 703;

[0037] The rotating platform 4 is arranged in the middle of the working platform 1, a third driving motor is arranged in the middle of the lower side of the rotating platform 4, a plurality of lower positioning fixtures 602 are arranged on the outer edge of the rotating platform 4, and a rotating motor 9 is arranged at the corresponding positions of the hollow tube 201, the lifting cylinder 501, the upper positioning fixture 601 and the base 701 on the working platform 1 under the rotating platform 4;

[0038] The placing mechanism 8 is arranged on a side of the working platform 1 corresponding to the hollow tube 201 .

[0039] The upper positioning tool 601 includes a fourth driving motor 606 for driving the upper mold 603 to rotate, and a third cylinder 607 for driving the fourth driving motor 606 to move up and down.

[0040] In this embodiment, the swing arm mechanism 3, lifting mechanism 2, edge cleaning mechanism 5, feeding mechanism 6 and shaping mechanism 7 are arranged clockwise along the outer edge of the rotating platform 4, so that after the lower mold 604 is grabbed onto the rotating platform 4 by the swing arm mechanism 3, the lower mold 604 is operated one by one, and finally the formed impeller is placed on the placement mechanism 8 through the swing arm mechanism 3.

[0041] In this embodiment, the first drive motor 205 , the second drive motor 302 , the third drive motor, the rotating motor 9 , and the fourth drive motor 606 are all stepping motors, so that each drive motor operates in a set manner.

[0042] In this embodiment, the swing arm 303 of the swing arm mechanism 3 is driven by the second drive motor 302 to reciprocate by 90°, thereby performing loading and unloading operations on the lower mold 604 and the molded blades.

[0043] When the present invention is running:

[0044] The lower mold 604 is loaded, and the shift fork on the lifting assembly 203 is inserted into the lower mold 604 at the lowest side on the placement mechanism 8. When the first drive motor 205 is running, it drives the chain 207 to run through the gear 206. The chain 207 drives the lifting assembly 203 to lift the lower mold to a position where the swing arm mechanism 3 can grab the lower mold 604; then, the first cylinder 304 at one end of the swing arm 303 in the swing arm mechanism 3 drives the pneumatic gripper 305 to move downward to grab the uppermost lower mold 604. At this time, the first cylinder 304 at the other end of the swing arm 303 drives the pneumatic gripper 305 to grab the finished impeller on the rotating platform 4. Then, the second drive motor 302 drives the swing arm 303 to rotate, so that the swing arm 303 places the lower mold 604 on the lower positioning tooling 602 on the rotating platform 4, and at the same time, the other end of the swing arm 303 places the formed impeller on the placement mechanism 8;

[0045] The lower mold 604 is cleaned. After the lower mold 604 is placed on the lower positioning fixture 602, the third driving motor drives the rotating platform 4 to rotate, and the placed lower mold 604 is transported to the cleaning mechanism 5. The lifting cylinder 501 contracts to drive the fixed arm 502 to move downward. When the edge grinding column 503 contacts the inner edge of the lower mold 604, the second cylinder 504 drives the first pressing column 505 to move downward to press the lower mold 604 on the lower positioning fixture 602. The rotating motor 9 at the cleaning mechanism 5 drives the lower positioning fixture 602 to rotate and drive the lower mold 604 to rotate. During the rotation of the lower mold 604, the edge grinding column 503 cleans the lower mold 604.

[0046] The lower mold 604 is fed with material. After the edge cleaning, the lower mold 604 is transported to the feeding mechanism 6 under the rotation of the rotating platform 4 driven by the third driving motor. The third cylinder 607 drives the fourth driving motor 606 to drive the upper mold 603 to move downward. When the upper mold 603 and the lower mold 604 collide with each other, the third cylinder 607 stops running. Then the fourth driving motor and the rotating motor 9 there drive the lower mold 604 to rotate. At the same time, the fourth driving motor 606 drives the upper mold 603 to rotate. At the same time, the feeding motor 605 runs during the rotation of the upper mold 603 and the lower mold 604 to drive the feeding mechanism polar blade to enter the mold. After the feeding of the lower mold 604 is completed, the fourth driving motor 606, the rotating motor 9 there and the feeding motor 605 stop running.

[0047] Impeller shaping: After the lower mold 604 is fed, it is conveyed by the rotating platform 4 under the drive of the third driving motor. When the lower mold 604 after feeding reaches the shaping mechanism 7, the third driving motor stops running, and then the fourth cylinder 702 pushes the slider 703 to move toward the lower mold 604, so that the shaping disk 704 touches the blades of the lower mold 604. At this time, the fourth cylinder 702 stops moving, and then the rotating motor 9 at this location drives the lower positioning tool 602 to rotate and drive the lower mold 604 to rotate. During the rotation of the lower mold 604, the shaping disk 704 regularizes the blades on the lower mold 604.

[0048] After the lower mold 604 is shaped, the fourth cylinder 701 contracts and drives the slider 703 to withdraw, while moving the shaping disk 704 away from the lower mold 604. Then the third drive motor drives the rotating platform 4 to rotate the position of the vertical rod 301 of the swing mechanism 3. The third drive motor stops running, and then the first cylinder 304 at this location drives the pneumatic gripper 305 to grab the formed impeller and place it on the placing mechanism 8, thereby completing the forming of the impeller. The impeller is continuously formed with the cooperation of various mechanisms, effectively realizing the fully automated forming of the impeller.

[0049] It should be pointed out that in order to control the orderly operation of each drive motor and cylinder, the present invention is also provided with a PLC controller and an industrial computer, so as to facilitate the user to set the operation sequence of each drive motor and cylinder.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
