Description

Technical Field

[0001] The present invention belongs to the technical field of rotor processing, and in particular relates to a rotor forging forging device and a forging method. Background Art

[0002] Rotor forgings are widely used in modern machinery, aerospace, energy, and other industries, requiring extremely stringent quality and performance requirements. Rotor forgings are typically produced through open-die forging and die forging. Die forging is widely used due to its high production efficiency and excellent product precision. The die forging process typically involves applying pressure using a forging hammer or hydraulic press, causing the metal blank to plastically deform within a die, forming the desired shape.

[0003] However, current die forging equipment, particularly hammer forging equipment, faces several technical bottlenecks in practical application. During the hammer forging process, different rotor forgings have varying structures and sizes, requiring significantly different hammer forging forces. Existing hammer forging equipment typically only has a fixed hammer forging force, making it difficult to flexibly adjust the hammer forging force when switching between different rotor forgings. This fixed hammer forging force limits the equipment's flexibility during production and leads to low production efficiency. Summary of the Invention

[0008] An adjusting mechanism, the adjusting mechanism comprising a spring and an adjusting assembly, wherein the adjusting assembly is used to adjust the initial extension of the spring;

[0009] When the hammer head rises, the spring is stretched based on the initial elongation to accumulate corresponding potential energy. When the hammer head falls freely, the spring energy is released and pulls the hammer head to accelerate its fall, thereby realizing the hammer forging of the blank on the die in a reciprocating manner.

[0016] As a preferred embodiment of the above technical solution, the connecting assembly includes a guide cylinder fixedly connected to the bottom of the forging box, and a lifting column is vertically slidably connected inside the guide cylinder. The bottom end of the lifting column is fixed to the top of the hammer head, and the end of the connecting rod away from the shift plate is movable through the bottom of the forging box and fixed to the outer wall of the lifting column.

[0020] S1. Preparation of blank: prepare the corresponding die for the forged part and install it on the base, then place the blank in the die cavity of the die;

[0021] S2. Spring adjustment: Based on the required hammer forging force corresponding to the blank, the initial elongation of the spring is adjusted by adjusting the components;

[0022] S3. Forging: The forging mechanism raises the hammer head and then releases it to fall freely.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example

[0031] like Figure 1-Figure 3 As shown, the rotor forging device includes:

[0032] A base 10, with a mold 20 disposed on the top of the base 10;

[0033] A forging mechanism 40 and a hammer head 50 , wherein the forging mechanism 40 raises the hammer head 50 and then releases it to freely fall, and the hammer head 50 freely falls to the blank on the die 20 ;

[0034] The adjusting mechanism 60 includes a spring 65 and an adjusting assembly, and the adjusting assembly is used to adjust the initial extension of the spring 65;

[0035] When the hammer head 50 rises, the spring 65 is stretched based on the initial elongation to accumulate corresponding potential energy. When the hammer head 50 falls freely, the spring 65 releases the stored energy and pulls the hammer head 50 to accelerate its fall, thereby realizing the reciprocating hammer forging of the blank on the die 20.

[0036] Before forging, the forging device of the present invention prepares the mold 20 corresponding to the workpiece to be forged and installs it on the base 10. Then, a blank is placed in the die cavity of the mold 20. Then, based on the required hammer forging force corresponding to the blank, the initial elongation of the spring 65 is adjusted by the adjustment component. During forging, the forging mechanism 40 raises the hammer head 50 and then releases it to free fall. When the hammer head 50 is raised, the spring 65 is stretched based on the initial elongation and accumulates corresponding potential energy. When the hammer head 50 is free fall, the spring 65 is released and pulls the hammer head 50 to accelerate its fall, thereby achieving reciprocating hammer forging of the blank on the mold 20. It should be noted here that since the height of the hammer head 50 is consistent, that is, the subsequent elongation of the spring 65 is consistent, the longer the initial elongation, the higher the final accumulated potential energy, that is, the greater the initial descent velocity and the forging hammer force.

[0037] A fixing plate 21 is provided on the outer side of the mold 20 , and the mold 20 is fixed to the top of the base 10 by the fixing plate 21 and bolts.

[0038] In this embodiment, the mold 20 is fixed to the base 10 via a fixing plate 21. In practical applications, the fixing plate 21 can be replaced by other connecting parts with the same function.

[0039] The forging mechanism 40 includes a forging box 41 , a driving assembly, and a connecting assembly.

[0040] As a preferred embodiment of the above technical solution, the forging box 41 is located directly above the die 20, and the hammer head 50 is located between the forging box 41 and the die 20;

[0041] The outer wall of the forging box 41 is fixedly connected to a column 30 , and the other end of the column 30 is fixedly connected to the top of the base 10 .

[0042] In the present invention, the pillars 30 play a supporting role, ensuring the stability of the forging box 41 and the overall structure of the forging mechanism 40.

[0043] The driving assembly includes a motor 42 mounted on the outer wall of the forging box 41. The output shaft of the motor 42 is mounted with a rotating shaft 43. The outer fixed sleeve of the rotating shaft 43 is provided with a rotating disk 44. The side of the rotating disk 44 is fixedly connected to a shifting post 45.

[0044] A shift plate 46 is vertically slidably connected to the inner wall of the forging box 41 , and a connecting rod 47 is fixedly connected to the bottom of the shift plate 46 .

[0045] The working principle of the drive assembly is as follows: the motor 42 drives the rotating shaft 43 and the turntable 44 to rotate. During the rotation of the turntable 44, the dial plate 46 is first driven to rise under the action of the dial post 45, and is connected with the connecting rod 47, thereby driving the lifting column 49 and the hammer head 50 to rise. After rising to the highest point, the dial post 45 is separated from the bottom of the dial plate 46. Under the action of gravity and the adjustment mechanism 60, the hammer head 50, the dial plate 46, the connecting rod 47, the lifting column 49 and other components are lowered as a whole. Then the dial post 45 continues to rotate until it returns to the bottom of the dial plate 46, and then drives the dial plate 46 to rise again, and so on. It should be noted that in actual application, the time for the hammer head 50 to drop to the bottom should be set to be less than the time for the dial post 45 to rotate and return to the bottom of the dial plate 46.

[0046] The connection assembly includes a guide cylinder 48 fixedly connected to the bottom of the forging box 41. A lifting column 49 is vertically slidably connected to the interior of the guide cylinder 48. The bottom end of the lifting column 49 is fixed to the top of the hammer head 50. The end of the connecting rod 47, away from the paddle 46, is movable through the bottom of the forging box 41 and fixed to the outer wall of the lifting column 49. A reinforcing rib 491 is fixedly connected between the outer wall of the lifting column 49 and the top of the hammer head 50 to further enhance the stability of the connection.

[0047] The adjustment mechanism 60 also includes a first sliding block 61 and a second sliding block 62 vertically slidably connected to the inner sidewall of the column 30. A spring 65 is fixedly connected between the first and second sliding blocks 61, 62. A linkage rod 66 is fixedly connected between the first sliding block 61 and the lifting column 49. The adjustment assembly includes a fixed block 63 fixedly connected to the inner sidewall of the column 30. A threaded rod 64 is threadedly inserted into the fixed block 63, and the top end of the threaded rod 64 is rotatably connected to the bottom of the second sliding block 62.

[0048] Under the connection of the connecting rod 66, the lifting column 49 and other components, the hammer head 50 rises and drives the first sliding block 61 to rise, so that the spring 65 is pulled up, thereby accumulating potential energy; when the hammer head 50 descends, the potential energy of the spring 65 is released to pull the hammer head 50 to accelerate the descent.

[0049] A forging method is applied to the above-mentioned rotor forging device, and the forging method comprises the following steps:

[0050] S1. Preparation of the blank: prepare the corresponding die 20 for the forged part and install it on the base 10, then place the blank into the die cavity of the die 20;

[0051] S2. Adjustment of the spring 65: Based on the required hammer forging force corresponding to the blank, the initial elongation of the spring 65 is adjusted by adjusting the components;

[0052] S3. Forging: The forging mechanism 40 raises the hammer head 50 and then releases it to fall freely. When the hammer head 50 is raised, the spring 65 is stretched based on the initial elongation to accumulate corresponding potential energy. When the hammer head 50 falls freely, the spring 65 releases the stored energy and pulls the hammer head 50 to accelerate its fall, thereby realizing the reciprocating hammer forging of the blank on the die 20.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
