Detailed implementation manners

[0028] The following further elaborates on the present invention in conjunction with the attached Figures 1-8 drawings.

[0029] Referring to Figures 1-8 , an embodiment of the present invention discloses a preforming forging device for a wind power bearing forging, which includes a forging table 1. On both sides in the middle of the forging table 1, horizontal plates 2 are fixedly installed. A storage structure and a pushing structure are arranged on the right horizontal plate 2, and a blanking and collecting structure is arranged on the left horizontal plate 2. A material pushing structure is arranged in the middle of the forging table 1. A transmission structure is arranged between the material pushing structure and the pushing structure. A through hole 4 is opened in the middle of the upper surface of the forging table 1. A forging structure is arranged above the forging table 1 at the position of the through hole 4. A forging limit ring 3 is arranged around the edge of the through hole 4 on the upper surface of the forging table 1. A cleaning and collecting structure is arranged on the forging table 1 at the position of the material pushing structure;

[0030] The material pushing structure includes a forging plate 8 arranged between the two horizontal plates 2. Support grooves 10 are opened at the edges of the two horizontal plates 2 close to each other. The forging plate 8 is supported in the support grooves 10. A through groove 9 is opened in the middle of the forging plate 8. A first cylinder 5 is installed in the middle of the lower surface of the forging table 1. The top of the hydraulic rod on the output shaft of the first cylinder 5 is connected with a lifting plate 6. A convex plate 7 is arranged in the middle of the upper surface of the lifting plate 6. The outer diameter of the convex plate 7 is the same as the inner diameter of the through groove 9. The outer diameter of the forging plate 8 is the same as the inner diameter of the through hole 4. After the forging is moved onto the forging plate 8, the first cylinder 5 can be started to drive the lifting plate 6 to move upward and insert into the forging plate 8, and the convex plate 7 is inserted into the through groove 9. The upper surface of the convex plate 7 is on the same horizontal plane as the upper surface of the forging plate 8. Then the first cylinder 5 continues to drive the lifting plate 6 to move upward, so as to lift the forging plate 8 on the support grooves 10 and send the forging to the forging limit ring 3 for forging work;

[0031] The forging structure includes a U-shaped frame 11 fastened to the middle of the upper surface of the forging table 1 by bolts. At the middle of the upper surface of the U-shaped frame 11, a second cylinder 12 is installed. At the bottom end of the output shaft hydraulic rod of the second cylinder 12, a forging hammer 13 is installed. The outer diameter of the forging hammer 13 is the same as the inner diameter of the forging limit ring 3. When the second cylinder 12 is started to drive the forging hammer 13 to move up and down, forging work can be carried out on the forging plate 8 for the forgings.

[0032] See Figure 1 , Figure 7 and Figure 8 , the storage structure includes a storage box 15 installed in the middle of the upper surface of the left cross plate 2. A groove 14 for the storage box 15 to pass through is opened at the middle of the upper right side of the forging table 1. A baffle 16 is hinged at the right side position of the storage box 15. A handle 17 is provided on the baffle 16. Feeding grooves 18 are opened at the bottom ends of the left and right sides of the storage box 15. The forgings to be forged can be stacked in the storage box 15, and when the baffle 16 is opened by using the handle 17, it is convenient to stack the forgings in the storage box 15;

[0033] The two ends of the handle 17 movably pass through the baffle 16. Slots for the two ends of the handle 17 to movably insert are opened at the corresponding positions on the side edge of the storage box 15. Fixed sleeves 19 are fixedly sleeved on the handle 17 near both ends. Springs 20 are sleeved on the handle 17 near both ends. The two ends of the spring 20 are respectively connected to the fixed sleeve 19 and the baffle 16. When the baffle 16 is closed on the storage box 15, the elastic force of the spring 20 can be used to pull the two ends of the handle 17 to insert into the slots on the storage box 15 to position the closed baffle 16 on the storage box 15.

[0034] See Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the pushing structure includes a pushing plate 21 closely attached to the upper surface of the cross plate 2. The pushing plate 21 movably passes through the feeding groove 18. Connecting strips 22 are connected to the front and rear side edges of the right side surface of the pushing plate 21. Vertical plates 23 are respectively connected to the ends of the two connecting strips 22 inserted into the forging table 1. The lower surface of the vertical plate 23 is closely attached to the lower inner wall of the forging table 1;

[0035] The transmission structure includes L-shaped rods 25 connected to the front and rear edges under the lifting plate 6. One end of the two L-shaped rods 25 extends to the position of the two vertical plates 23. Push-pull grooves 24 are provided on both vertical plates 23. The push-pull grooves 24 are in an "S"-like shape. The end of the L-shaped rod 25 far from the lifting plate 6 is movably inserted into the push-pull groove 24. When the first cylinder 5 drives the lifting plate 6 and the forging plate 8 to move downward, the forging plate 8 is supported on the support groove 10. As the lifting plate 6 continues to move downward, the lifting plate 6 is pulled out from below the forging plate 8, and the lifting plate 6 drives one end of the L-shaped rod 25 to move downward in the push-pull groove 24, thereby driving the vertical plate 23 to move on the forging table 1. The push plate 21 is pulled on the cross plate 2 through the connecting bar 22 to automatically push the lowermost forging in the storage frame 15 onto the forging plate 8, realizing the automatic feeding function.

[0036] See Figure 1 、 Figure 2 and Figure 4 For the blanking structure, it includes a blanking plate 26 connected to the left cross plate 2. The blanking plate 26 is inclined. Shielding edges are provided at the front and rear edges on the upper surface of the blanking plate 26. A first receiving frame 27 is provided below the lower end of the blanking plate 26. The first receiving frame 27 is placed on the forging table 1. After forging, when the push plate 21 continues to push the lowermost forging in the storage frame 15 onto the forging plate 8, the forged forging on the forging plate 8 can be pushed onto the blanking plate 26 and discharged into the first receiving frame 27 for collection through the blanking plate 26.

[0037] The cleaning and collection structure includes a U-shaped plate 28 connected to the front of the forging table 1 at the position of the forging plate 8. An electric telescopic rod 29 is installed in the middle of the front of the U-shaped plate 28. One end of the output shaft of the electric telescopic rod 29 is connected to a cleaning plate 30. Brush hairs 31 are provided below the cleaning plate 30. A second receiving frame 32 is placed in the middle below the rear side of the forging table 1. When the electric telescopic rod 29 is started to move, the brush hairs 31 on the cleaning plate 30 can clean the residues on the forging plate 8 into the second receiving frame 32, which is convenient for centralized treatment.

[0038] The implementation principle of a pre - forming forging device for a wind power bearing forging in an embodiment of the present invention is as follows: First, use the handle 17 to open the baffle 16 on the storage frame 15, stack the forgings to be forged into the storage frame 15, close the baffle 16 again, and use the elasticity of the spring 20 to pull the end of the handle 17 into the slot on the storage frame 15 to position the closed baffle 16 on the storage frame 15. Then start the first cylinder 5 to drive the lifting plate 6 to move downward. The lifting plate 6 moves out from below the forging plate 8. One end of the L - shaped rod 25 driven by the lifting plate 6 slides downward in the push - pull groove 24, pushing the vertical plate 23 to move away from the storage frame 15. The push - material plate 21 is driven by the connecting bar 22 to move in the feeding groove 18 at the bottom of the storage frame 15, and the lowermost forging in the storage frame 15 is pushed onto the forging plate 8. Then the first cylinder 5 drives the lifting plate 6 to move upward and insert into the forging plate 8. The upward movement of the L - shaped rod 25 in the push - pull groove 24 is used to drive the push - material plate 21 to move reversely and reset on the cross - plate 2. The remaining forgings in the storage frame 15 fall and are supported on the cross - plate 2. Then the first cylinder 5 continues to drive the lifting plate 6 to move upward, thereby lifting the forging plate 8 and the forgings as a whole on the support groove 10 to send the forgings into the forging limit ring 3. And start the second cylinder 12 on the U - shaped frame 11 to drive the forging hammer 13 to move up and down to perform forging work on the forging on the forging plate 8. After forging, the first cylinder 5 drives the forging plate 8 to move downward and support it in the support groove 10. Then the lifting plate 6 moves out from below the forging plate 8. The lifting plate 6 continues to move downward, driving one end of the L - shaped rod 25 to slide downward in the push - pull groove 24 to continue pulling the push - material plate 21 to move, pushing the lowermost forging in the storage frame 15 onto the forging plate 8, and pushing the forged forging on the forging plate 8 onto the blanking plate 26. The blanking plate 26 automatically blanks the forgings into the first collection frame 27 for collection. In this way, the forging work can be completed.

[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
