Description

Technical Field

[0001] This utility model relates to the field of forging, and more specifically, to a forging device for annular workpieces. Background Technology

[0002] A ring forging mill is a forging machine specifically designed for producing ring-shaped forgings. It applies high temperature and pressure to a metal billet, causing plastic deformation of the material to obtain ring-shaped parts with specific dimensions and mechanical properties. Ring forging mills are widely used in various industrial fields such as aerospace, automotive, and energy because ring forgings can withstand harsh working environments such as prolonged exposure to high temperatures, high pressures, high speeds, and vibrations.

[0003] A search revealed an existing patent (publication number: CN220216599U) that discloses a forging device for forging rings, comprising a machine body, an ejection mechanism within the machine body, a bracket welded to the machine body, a hydraulic cylinder fixedly mounted on the bracket, a hydraulic rod mounted on the hydraulic cylinder, the hydraulic rod slidably connected to the bracket, a hanging plate welded to the hydraulic rod, a forging hammer fixedly mounted on the hanging plate, a protective sleeve adhered to the hanging plate, and a counterweight ring adhered to the protective sleeve. This invention, through the inclusion of a support ring, motor, gears, a gear ring, a screw barrel, and a screw rod, utilizes a motor to drive the gears to rotate and engage with the gear ring, thereby causing the screw barrel and screw rod to perform threaded motion. This, in turn, causes the screw rod to move the support ring, ejecting the forging from the device, thus making removal after processing more convenient. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing ring workpiece forging equipment often only has a forging function during the forging process. When the workpiece deviates, it is often necessary to manually fix and adjust the forging billet, and at the same time, it is necessary to manually rotate and adjust the workpiece to ensure that the force is evenly distributed.

[0005] Therefore, a ring-shaped workpiece forging device is proposed to address the above problems. Utility Model Content

The rotating cylinder 10 is driven by the servo motor 14 to rotate. The rotation of the rotating cylinder 10 drives the threaded rod 11 to move in translation, thereby driving the arc-shaped fixed clamping plate 12 to clamp and adjust the forging to keep it in the center position, thus preventing the forging from shifting during the forging process. The rotating shaft 15 is driven by the forward and reverse motor 18 to rotate forward or reverse. The rotation of the rotating shaft 15 drives the roller 16 to rotate. The friction ring 17 plays a role in increasing the friction force. The two rollers 16 rotate in opposite directions to rotate and adjust the clamped workpiece, so that the workpiece is subjected to uniform force during the forging process, without the need for manual adjustment. After the workpiece is forged to a certain extent, the top block 20 can be pushed out by the hydraulic telescopic cylinder 19, which will cooperate with the protrusion 6 at the bottom of the forging head 5 to punch a hole in the center of the billet, forming a ring-shaped workpiece. The forged ring-shaped workpiece can be placed on the surface of the ring forging machine frame 21. The auxiliary shaft 26 is pushed to the workpiece by the electric telescopic rod 25. By inserting the auxiliary shaft 26 into the center of the ring-shaped workpiece, the drive motor 221 is started. The drive motor 221 drives the drive shaft 23 to rotate, which in turn drives the drive wheel 24 to rotate. The electric telescopic rod 25 drives the auxiliary shaft 26 and the workpiece to move towards the drive wheel 24. When the ring-shaped workpiece contacts the drive wheel 24, it will be driven to rotate. At the same time, it will be squeezed by the auxiliary shaft 26 on its inner wall, so that it forms a ring-shaped workpiece under high-speed rotation. At the same time, the second electric telescopic rod 27 and the auxiliary wheel 28 play an auxiliary role to facilitate the formation of a regular ring-shaped workpiece. The above is the working principle of this ring-shaped workpiece forging device.
