Description

Technical Field

[0001] The utility model relates to the technical field of flange forging dies, in particular to a flange forging die. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects pipes to each other. For some large connecting flanges, most of them are produced by forging. The production and processing of forged flanges requires the use of special forging dies. Die forging refers to heating the metal to a liquid or softened state first, then putting it into the mold, and forming it in one go by closing the upper and lower dies of the mold, sometimes multiple times. The difference between it and casting is that casting is to pour the heated molten metal directly into the model, while die forging also requires the closing of the upper and lower dies, and is subjected to extrusion pressure during the forming process, so the organization and mechanical properties of die forgings are better than those of castings.

A buffer seat is fixedly installed at the bottom of the lower die seat, and a base is fixedly installed at the bottom of the buffer seat. Four mounting blocks are fixedly installed on the top of the lower die seat. The bottom of the buffer seat is slidably connected to the buffer groove, and a buffer spring is fixedly installed at the top of the inner top of the buffer groove.
