[0050] In the embodiment of the present invention, the upper mold assembly 3 includes a cylinder and an upper mold, the lower part of the cylinder is fixedly connected to the fixed housing 1, and the upper mold is fixedly connected to the upper part of the cylinder. When the lower mold 41 on which the steam turbine blade to be shaped is placed is located below the upper mold assembly 3, the cylinder drives the upper mold to move downward, so that the upper mold presses the steam turbine blade to be shaped in the lower mold 41 downward, so that the steam turbine blade is processed and shaped in the mold cavity 411 of the lower mold 41. After the processing and shaping, the cylinder drives the upper mold to move upward;

[0051] The second electromagnet 71 is electrically connected to the second control power supply. Since the second control power supply is of the same model as the first control power supply 61, the second control power supply is not shown in the drawings.

[0052] The specific working principle of the CCD detection system 5 is relatively mature in the prior art and will not be described in detail.

[0053] See also Figures 5 to 20In one embodiment of the present invention, the lower mold assembly 4 further includes a limiting rib 421, a center sleeve 422 and a fixing plate 44, the limiting rib 421 is arranged on the surface of the center shaft 42, the transmission gear 43 is movably sleeved on the center shaft 42 and the surface of the limiting rib 421, the center sleeve 422 is fixedly sleeved at the center position of the center shaft 42, the center shaft 42 is movably connected to the surface of the rotating shell 22 through the center sleeve 422, the fixing plate 44 is fixedly connected to the surface of the center shaft 42, and when the transmission gear 43 is meshed with the first tooth groove segment 15 and the second tooth groove segment 16, the transmission gear 43 is in contact with the fixing plate 44.

[0054] In the embodiment of the present invention, when the lower mold assembly 4 follows the rotating shell 22 to rotate toward the unloading mechanism 7, the transmission gear 43 drives the transmission gear 43 to rotate by meshing with the first tooth groove segment 15. The rotating transmission gear 43 drives the lower mold 41 and the center axis 42 to rotate 180 degrees through the limiting rib 421.

[0055] See also Figures 6 to 20 In one embodiment of the present invention, the adjustment system 6 also includes a first control power supply 61, a conductive ring 62 and a first return spring 64.

The first return spring 64 is connected between the first electromagnet 63 and the transmission gear 43.

[0056] In an embodiment of the present invention, when the central computer system 9 determines that the finalized turbine blade is unqualified, the central computer system 9 drives the control switch corresponding to the lower mold 41 to open, thereby energizing the first electromagnet 63. The magnetic attraction between the energized first electromagnet 63 and the magnet ring 431 drives the transmission gear 43 to move in a direction away from the fixed plate 44.

[0057] See also Figures 7 to 15 In one embodiment of the present invention, the unloading mechanism 7 further includes a second return spring 74 movably sleeved on the surface of the movable bending rod 72 , and the second return spring 74 is connected between the second electromagnet 71 and the bracket 17 .

[0060] Working principle: Reference Fig.16 The driving part 21 drives the rotating shell 22, the lower mold assembly 4 and the adjustment system 6 to rotate counterclockwise around the axis of the fixed shell 1 through the meshing teeth 23. When the lower mold 41 of the lower mold assembly 4 moves to the bottom of the feeding robot 8, the feeding robot 8 places the turbine blade to be shaped on the top of the lower mold 41. When the lower mold 41 moves to the bottom of the upper mold assembly 3, the upper mold assembly 3 processes and shapes the turbine blade in the mold cavity 411 of the lower mold 41 by downward extrusion. It should be noted that a support plate is also provided at a position below the upper mold assembly 3 in the fixed shell 1, and the support plate is not shown in the accompanying drawings. When the lower mold 41 rotates to the bottom of the upper mold assembly 3, the lower surface of the lower mold 41 contacts the support plate, and the support plate plays a role in supporting the lower mold 41 upward. After processing and shaping, the upper mold assembly 3 rises upward, and the lower mold 41 continues to follow the rotating shell 22 to move to the bottom of the CCD detection system 5. The CCD detection system 5 takes a picture of the shaped turbine blade and uploads the picture data to the central computer system 9.

[0061] (1) When the central computer system 9 determines that the finalized steam turbine blade is qualified:

[0062] refer to Fig.16 and Fig.17In the process of the lower mold assembly 4 following the rotating shell 22 to rotate toward the unloading mechanism 7, the transmission gear 43 drives the lower mold 41 to rotate 180 degrees around the central axis 42 by meshing with the first tooth groove segment 15. When the lower mold 41 moves to the bottom of the unloading mechanism 7 after rotating 180 degrees, there are the following two situations: first, the turbine blades processed and shaped in the mold cavity 411 automatically fall into the fixed shell 1; second, the turbine blades processed and shaped in the mold cavity 411 are stuck in the mold cavity 411. At this time, the central computer system 9 controls the second electromagnet 72 to be energized. The magnetic attraction between the energized second electromagnet 72 and the magnet block 73 drives the movable bent rod 72 to move toward the interlayer 412. The movable bent rod 72 is in sliding contact with the wedge block 454 to drive the top block 451 away from the hidden hole. The purpose of the movement of 4111 is that the ejector block 451 can eject the turbine blade stuck in the mold cavity 411. At the same time, the second electromagnet 72 is powered off, and the second reset spring 74 drives the movable bending rod 72 to reset. The third reset spring 453 drives the ejector block 451 to reset. When the lower mold assembly 4 continues to rotate toward the loading robot 8 following the rotating shell 22, the transmission gear 43 will also be connected to the second tooth groove section 16. At this time, the lower mold 41 rotates 180 degrees again, and the pusher plate 24 that rotates with the rotating shell 22 can push the turbine blade in the fixed shell 1 to the qualified product discharge port 12. It should be noted here that only one pusher plate 24 is shown in the accompanying drawings. In actual use, a pusher plate 24 should be set between two adjacent lower mold assemblies 4, and the qualified turbine blades will eventually slide down along the guide inclined plate 14.

[0063] (2) When the central computer system 9 determines that the finalized steam turbine blade is unqualified:

[0064] The central computer system 9 drives the first electromagnet 63 corresponding to the lower mold 41 to be energized through the first control power supply 61. The magnetic attraction between the energized first electromagnet 63 and the magnet ring 431 drives the transmission gear 43 to move in the direction away from the fixed plate 44. When the first electromagnet 63 fits with the magnet ring 431, the transmission gear 43 is disengaged. At this time, when the lower mold 41 moves to the bottom of the unloading mechanism 7, the central computer system 9 controls the second electromagnet 72 to be energized. The magnetic attraction between the energized second electromagnet 72 and the magnet block 73 drives the movable bending rod 72 to move toward the interlayer 412. The movable movable bending rod 72 and the wedge block 454 are in sliding contact with each other to achieve the purpose of driving the top block 451 to move away from the hidden hole 4111. The top block 451 can push out the turbine blade stuck in the mold cavity 411. At the same time, the second electromagnet 72 is powered off, and the second return spring 7 4 drives the movable bending rod 72 to reset, the third reset spring 453 drives the top block 451 to reset, and the central computer system 9 controls the first electromagnet 63 to be powered off. At this time, the elastic deformation of the first reset spring 64 drives the transmission gear 43 to reset. When the lower mold 41 continues to rotate toward the defective product discharge port 13 following the rotating shell 22, the transmission gear 43 drives the lower mold 41 to rotate 180 degrees around the central axis 42 by rotating with the second tooth groove segment 16. At this time, the turbine blades processed and shaped in the mold cavity 411 of the lower mold 41 fall into the fixed shell 1. When the lower mold assembly 4 continues to rotate toward the feeding robot 8 following the rotating shell 22, the push plate 24 that rotates with the rotating shell 22 can push the turbine blades in the fixed shell 1 to the defective product discharge port 13, and the unqualified turbine blades finally slide down along the guide inclined plate 14.

[0065] To sum up, the fixed shell 1, the rotating mechanism 2, the upper mold assembly 3, the lower mold assembly 4, the CCD detection system 5, the adjustment system 6, the unloading mechanism 7 and the loading robot 8 cooperate with each other, which not only realizes the functions of automatic loading, shaping, detection and unloading of turbine blades, but also can automatically classify and collect qualified turbine blades and unqualified turbine blades, and has the characteristics of high degree of automation, strong practicality and high work efficiency.
