Description

Technical Field

[0001] The utility model relates to the technical field of square shaft processing, and more specifically to a square shaft processing device for a hot die forging press. Background Art

[0002] In the clutch mechanism of a large hot forging press, a wedge key is used for the assembly of the shaft and the hub. Due to various reasons, the contact area between the wedge key and the square shaft will cause a depression on the surface of the square shaft. When the depression is deep, the surface of the square shaft needs to be repaired.
