[0031] Initially, the lower die 5 and the upper die 6 are both located directly below the forging head of the forging machine body 2; when the anchor chain needs to be forged, the fired steel blank 001 is first taken out of the furnace by a manual tool and placed in the semi-cylindrical groove on the top surface of the support seat 17, and then the mechanical arm 8 is controlled to drive the connecting frame 12 to move to the front end of the steel blank 001 until the rear side of the limiting cone block 18 contacts the front end surface of the steel blank 001, that is, the steel blank 001 is positioned. At this time, the two clamps 13 can be respectively located at the steel blank 001 and the front end surface of the steel blank 001. 01 is moved to the appropriate position on the left and right sides of the steel blank 001, and then the electric push rod Ⅰ 14 drives the clamps 13 on the left and right sides to move towards each other, so that the two clamps 13 can clamp the front end of the steel blank 001, and then the mechanical arm 8 can be controlled to drive the steel blank 001 to move, so that the steel blank 001 passes between the lower die 5 and the upper die 6, and then the electric push rod Ⅰ 14 drives the clamps 13 to release the steel blank 001. At this time, the steel blank 001 is placed on the top surface of the lower die 5. At this time, the forging machine body 2 can be controlled to drive its forging head to move downward. The upper die 6 is hammered to squeeze the upper die 6 to move downward close to the lower die 5, the reset spring 7 is compressed, and the upper die 6 and the lower die 5 cooperate to extrude the steel blank 001. At this time, the clamp 13 and the steel blank 001 are in a separated state, so the clamp 13 and the robot arm 8 are not affected. Then the forging machine body 2 is controlled to drive its forging head to move upward away from the upper die 6, the reset spring 7 will return to its original state, and drive the upper die 6 to move upward and reset, and then the clamp 1 is driven by the electric push rod Ⅰ14 3. Clamp the steel blank 001 again, and then drive the main shaft 11 to rotate a certain angle through the steel blank 001. The main shaft 11 can drive the connecting frame 12 and the clamp 13 to rotate a certain angle. The clamp 13 can drive the steel blank 001 to rotate a certain angle between the lower mold 5 and the upper mold 6. Repeat the above operation, so that the upper mold 6 and the lower mold 5 can cooperate to extrude the steel blank 001 again. In this way, the steel blank 001 can be extruded in all directions to make the steel blank 001 into the shape of the initial blank I 002.Then, the robot arm 8 is controlled to clamp the embryo Ⅰ002 through the clamp 13, and drive the embryo Ⅰ002 to move to the top of the moving frame 20, and then the clamp 13 is controlled to release the embryo Ⅰ002, so that the embryo Ⅰ002 can fall into the placement groove 2001, and then the support plate 4 can be driven to move to the left by the electric slide rail 15 and the rubber block 16, until the support plate 4 drives the moving frame 20 to move to the left to the bottom of the forging head of the forging press body 2, and the moving frame 20 can drive the embryo Ⅰ002 to move to the left, so that the rear end of the embryo Ⅰ002 is located under the forging head of the forging press body 2, and then the forging press body 2 is controlled to drive its forging head to move downward to flatten the rear end of the embryo Ⅰ002, and then the forging press body 2 is controlled The forging head is driven to move upward and reset, and then the connecting block 22 is driven to move backward through the electric push rod II 21, and the connecting block 22 can drive the moving frame 20 to move backward, and the moving frame 20 can drive the initial blank I002 to move backward, so that the front end of the initial blank I002 is located directly below the forging head of the forging machine body 2, and then the forging machine body 2 is controlled to drive its forging head to move downward to flatten the front end of the initial blank I002, and then the forging machine body 2 is controlled to drive its forging head to move upward and reset, so that the initial blank I002 can be made into the shape of the initial blank II003; and then the connecting block 22 is driven to move forward through the electric push rod II 21, and the connecting block 22 can drive the moving frame 20 to move forward until the wedge block 24 passes through the square hole 23. After entering the placement groove 2001, the wedge block 24 can press and lift the front end of the initial blank Ⅱ003 in the placement groove 2001 upwards through its inclined surface, so that the clamp 13 can clamp the initial blank Ⅱ003. At the same time, the electric push rod Ⅱ21 can be controlled to drive the connecting block 22 to move backward and reset. The connecting block 22 can drive the moving frame 20 to move backward and reset, so that the wedge block 24 passes through the square hole 23 away from the placement groove 2001, and then the electric slide rail 15 and the rubber block 16 can drive the support plate 4 to move to the left until the support plate 4 drives the rotating die 27 to move to the left to just below the forging head of the forging machine body 2, and then the robot arm 8 is controlled to drive the initial blank Ⅱ003 to move to the top surface of the rotating die 27 through the clamp 13. , and then control the clamp 13 to release the initial blank Ⅱ003, and then control the forging press body 2 to drive its forging head to reciprocate up and down. The forging head of the forging press body 2 moves downward to hammer the pressure plate 31, so that the pressure plate 31 moves downward to hammer the initial blank Ⅱ003, so that the initial blank Ⅱ003 can be knocked into the rotating die 27, and the connecting spring Ⅰ30 is stretched. The forging head of the forging press body 2 moves upward to separate from the pressure plate 31, and the connecting spring Ⅰ30 will return to its original state, driving the pressure plate 31 to move upward and reset. In this way, the pressure plate 31 can reciprocate and hammer the initial blank Ⅱ003, so that the initial blank Ⅱ003 is formed into the finished product 004 in the rotating die 27. Since the finished product 004 is U-shaped when it is formed (such as; Fig.10As shown), the final pressing plate 31 will be clamped by the finished product 004. At this time, the driving motor 34 can be used to drive the rotating die 27 to rotate rightward by 90 degrees. The rotating die 27 will drive the fixing frame 28 to rotate rightward by 90 degrees and rest on the top surface of the square plate 33. The two limiting plates 35 are respectively located on the front and rear sides of the square plate 33 to play a limiting role. At this time, the top surface of the square plate 33 can resist the bottom surface of the finished product 004, and then the electric slide rail 15 and the rubber block 16 can be used to drive the support plate 4 to move to the left, until the support plate 4 drives the pressing plate 31 to move leftward to the forging head of the forging press body 2, and then the forging press body 2 is controlled to drive its forging The ram reciprocates up and down, and the forging ram of the forging machine body 2 moves downward to hammer the pressure plate 31, so that the pressure plate 31 and the slide plate 29 move downward together, and the connecting spring II 32 is stretched. The finished product 004 cannot move downward due to the obstruction of the square plate 33, and finally the pressure plate 31 and the finished product 004 can be separated, so that the forging forming work of the anchor chain can be automatically completed. During the entire forging process, the rubber block 16 also has a shock-absorbing effect, preventing the support plate 4 from transmitting vibration to the electric slide rail 15, thereby ensuring the normal operation of the electric slide rail 15, and the entire forging process does not require manual participation, saving time and effort, and improving work efficiency.

[0032] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
