Description

Technical Field

[0001] The utility model relates to the technical field of forged output shafts, in particular to a forged output shaft dedicated to a reducer. Background Art

[0002] Forging technology is one of the important technologies in industrial production and is widely used in aviation, aerospace, machinery, shipbuilding and other fields. Forging technology is a processing method that uses forging machinery to apply pressure to metal billets to cause them to undergo plastic deformation to obtain forged parts with certain mechanical properties, shapes and sizes. Forging can eliminate defects such as as-cast looseness produced during the metal smelting process and optimize the microstructure. At the same time, because the complete metal flow lines are preserved, the mechanical properties of forged parts are generally better than those of cast parts made of the same raw materials. Important parts in mechanical equipment with high loads and severe working conditions are mostly forged parts.

[0003] The patent document with the published announcement number CN 215614784 U discloses a forging device for producing the output shaft of a planetary reducer, which relates to the field of forging devices and includes a base plate, a horizontal control oil cylinder is arranged on the top of one end of the base plate, one end of the horizontal control oil cylinder is fixedly connected to one side of the motor seat, and a support shaft is arranged on the other side of the motor seat, and a clamping seat is arranged at one end of the support shaft, and a clamping plate is movably connected to the inner side of the clamping seat, and one end of the clamping plate is threadedly connected to the outer side of the control screw. The utility model uses a clamping plate, a sliding rod, a control screw and a clamping motor to horizontally clamp the forged original with uniform clamping force distribution, and while stably clamping the forged original, it avoids excessive or insufficient local clamping force causing the forged original to form too deep clamp marks or fall off, and through the use of a horizontal support, the support shaft can always maintain a stable horizontal posture.

[0004] However, the above-mentioned components still have certain defects, the most obvious of which is that when using them, if you want to replace the forging hammer mechanism, you need to remove the bolts first, and then you can replace the forging hammer mechanism, which is inconvenient to use.
