DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. As long as the effects of the present invention can be exerted, various changes can be made to the implementation scheme.
[0027] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0028] Reference Figure 1-7 A feeding mechanism for forging a ship shaft forging according to the present embodiment will be described.
[0029] like Figure 1 and Figure 2As shown, the feeding mechanism includes a ground rail 1 and a first material receiving mechanism 2, a second material receiving mechanism 3 and a driving adjustment mechanism 7 arranged at the front side of the forging machine for processing shaft forgings.
[0030] like Figure 1 and Figure 2 As shown, the first material receiving mechanism 2 and the second material receiving mechanism 3 both receive the shaft forgings and move them on the ground rail 1; during operation, a crane is used to lift the marine shaft forgings onto the first material receiving mechanism 2 and the second material receiving mechanism 3. The first material receiving mechanism 2 and the second material receiving mechanism 3 are pushed to carry the marine shaft forgings close to the forging press and enter the processing end of the forging press.
[0031] The driving and adjusting mechanism 7 is rotatably disposed in the cavity 8 inside the second material receiving mechanism 3; wherein the driving and adjusting mechanism 7 drives the shaft forging to move along the laying direction of the ground rail 1 or drives the shaft forging to spin on the first material receiving mechanism 2 and the second material receiving mechanism 3. When the shaft forging needs to be adjusted in a micro distance, the driving and adjusting mechanism 7 can be used to adjust the shaft forging. Moreover, after the driving and adjusting mechanism 7 rotates 90°, the shaft forging can be rotated, which facilitates the forging press to process the shaft forging.
[0032] like Figure 2 As shown, the ground rail 1 includes two outer rails 1b arranged in parallel, and the inner side of the outer rail 1b is connected to the inner rail 1a through a connecting beam 1c; the bottom of the first material supporting mechanism 2 and the second material supporting mechanism 3 are both provided with a first rail groove 4, and the first rail groove 4 is embedded in the outer rail 1b; the bottom of the first material supporting mechanism 2 is also provided with a second rail groove 5, and the second rail groove 5 is embedded in the inner rail 1a.
[0033] During actual processing, the shaft forging is finally extended to the processing end of the forging press, leaving the tail end of the shaft forging on the second material receiving mechanism 3. At this time, the weight of the shaft forging is borne by the forging press and the first material receiving mechanism 2, so the first track groove 4 and the second track groove 5 are used to receive the first material receiving mechanism 2.
[0034] like Figure 3 As shown, the first material receiving mechanism 2 includes a first base 21 , a first receiving platform 22 , a first pressing platform 23 and an impact platform 24 .
[0035] The first track groove 4 and the second track groove 5 are formed on the first base 21; the first receiving platform 22 is formed on the first base 21; the first press platform 23 is movably connected to the top of the first receiving platform 22 through a connecting assembly 25; the impact platform 24 is formed on the top surface of the first press platform 23. The inner sides of the first press platform 23 and the first receiving platform 22 form a cavity that can accommodate shaft forgings. The shaft forgings are lifted by a crane and then inserted horizontally into the cavity. The function of the impact platform 24 is to withstand the impact force of the punching machine, so that the first press platform 23 can move on the first receiving platform 22, forming the first press platform 23 into a forging body, and shaping the surface of the shaft forgings.
[0036] like Figure 4 As shown, the connecting assembly 25 includes an outer cylinder 254, an inner cylinder 253 and a spring 252. The outer cylinder 254 is fixed on the first receiving platform 22. One end of the inner cylinder 253 is movably connected in the outer cylinder 254, and the other end of the inner cylinder 253 is provided with an upper connecting platform 251, which is fixed on the first pressing platform 23; the spring 252 is sleeved on the inner cylinder 253, and the two ends of the spring 252 are respectively fixed on the upper connecting platform 251 and the outer cylinder 254. When the first pressing platform 23 is impacted, the first pressing platform 23 moves downward in the outer cylinder 254 with the upper connecting platform 251 and the inner cylinder 253, and compresses the spring 252. When the impact force is lost, the first pressing platform 23 is driven to reset by the driving force of the spring 252.

The guide column 34 is fixed on the second receiving platform 32; the guide sleeve 33 is fixed on the second pressing platform 35, and the guide column 34 passes through the guide sleeve 33. Through the arrangement of the guide column 34 and the guide sleeve 33, the distance between the second pressing platform 35 and the second receiving platform 32 can be adjusted.
[0039] like Figure 6 and Figure 7 As shown, the driving and adjusting mechanism 7 includes a bracket 71, a cavity 79, a side base seat 72, an arc plate 74, a main shaft rod 75, a support seat 710 and a plurality of rolling wheels.
[0040] The bracket 71 is circular in top view projection, and can rotate on the second receiving platform 32 when rotated; the top surface of the bracket 71 is an arc-shaped curved surface 73 from the outside to the inside. A cavity 79 is formed in the bracket 71. The side base seat 72 is fixed on both sides of the cavity 79. The arc plate 74 is snapped on the cavity 79 and fixed on the side base seat 72. The arc-shaped curved surface 73 and the arc plate 74 are combined with the second receiving platform 32 to form an arc surface. The main shaft rod 75 is rotatably connected to the side base seat 72.

A plurality of rolling wheels are rotatably connected to the main shaft rod 75, and the rolling wheels pass through the arc plate 74. One end of the shaft forging overlapped at the second receiving platform 32 can be adjusted forward and backward by a rolling wheel, which assists the forging process of moving the shaft forging forward and backward, prevents hard friction between the shaft forging and the second receiving platform 32, and improves the processing and forging effect.

[0042] like Figure 6 As shown, a rotating device is provided at the bottom of the driving and adjusting mechanism 7 , and the rotating device includes an upper base 14 , a lower base 16 , a power mechanism 13 , a guide connecting column 9 , a cylindrical cavity 10 and a compression spring 11 .

[0044] The power mechanism 13 drives the bracket 71 to rotate 90 degrees, and then the shaft forging is placed on the driving and adjusting mechanism 7. At this time, when the flip machine clamps the other end of the shaft forging and rotates, the rolling wheel can rotate to prevent the shaft forging from hard friction with the second receiving platform 32, and at the same time, it can also improve the rotation freedom of the shaft forging and improve the processing and forging effect.
[0045] Hydraulic cylinders 12 are fixed on both sides of the bottom of the lower base 16, and the hydraulic cylinders 12 are fixed on the second base 31. During the advancement and retraction of the hydraulic cylinders 12, the carrying brackets 71 rise and fall, so that the driving and adjusting mechanism 7 can enter and exit the working state.

It also includes a plurality of rollers. The driving wheel 66 is arranged in the first track groove 4, and the roller is arranged in the second track groove 5, and is used in conjunction with the driving wheel 66.
[0047] The first base 21 and the second base 31 are formed with an assembly cavity on the side. The support platform 61 is fixed in the assembly cavity on the side of the first base 21 or the second base 31; the main shaft 63 is rotatably connected to the support platform 61; the driving wheel 66 is fixed on one end of the main shaft 63, and the driving wheel 66 extends into the first track groove 4; the first gear 62 is fixed on the other end of the main shaft 63; the servo motor 64 is fixed on the first base 21 or the second base 31, and the output end of the servo motor 64 extends into the assembly cavity; the second gear 65 is fixed on the output end of the servo motor 64, and the second gear 65 is meshed with the first gear 62.
[0048] In the specific implementation process, the servo motor 64 drives the second gear 65 to rotate, and the second gear 65 drives the first gear 62 and the main shaft 63 to rotate, and the main shaft 63 rotates to drive the driving wheel 66 to rotate. When the driving wheel 66 rotates, it cooperates with the roller to drive the first material bearing mechanism 2 and the second material bearing mechanism 3 to move.
