[0039] The size adjustment device 3 is closely attached to the inner wall of the accommodation space of the large outer jacket 2 and is connected to the lower anvil 1;

[0040] A connecting plate 4, one side of which is connected to the top end of the size adjustment device 3;

[0041] The upper anvil 5 is connected to the other side of the connecting plate 4 .

[0042] In this embodiment, an ejector 6 is provided below the accommodation space of the large outer jacket 2, and the ejector 6 is connected to the lower anvil 1, and the ejector 6 can move linearly along the axis of the large outer jacket 2.

[0045] The shaft neck length adjustment sleeve 32 is located in the accommodation space of the shaft neck diameter adjustment sleeve 31 and is connected to the ejection device 6.

After the forging of the workpiece is completed, the cylinder pushes the ejection device 6, and the ejection device pushes the shaft neck length adjustment sleeve 32 to eject the workpiece upward, so as to facilitate the removal of the workpiece. In the actual production process, the shaft neck length adjustment sleeve 32 can be adjusted according to different production requirements to meet different production requirements;

[0046] The shaft diameter adjustment sleeve 33 has one end connected to the shaft neck diameter adjustment sleeve 31, and has an accommodation space that passes through from top to bottom.

[0047] The shaft extension sleeve 34 has one end connected to the shaft diameter adjustment sleeve 33 and is fixedly connected to the large outer sleeve 2. A vertically through-going accommodation space is provided inside the shaft extension sleeve 34.

[0059] S6, the blank is put into the mold and the guide sleeve is installed;

[0060] S7, the upper pressure head presses down, and the pressing force is 12000~13500t;

[0061] S8. After forming, quickly disassemble the guide sleeve and eject the planetary shaft;

[0062] S9, air cooling after demoulding.

[0064] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0065] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0067] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
