TECHNICAL FIELD

[0001] The utility model relates to blade production equipment technical field especially a kind of equipment fuselage and anvil device for blade forging processing. BACKGROUND

[0002] Blade is the key part of steam turbine, it withstands high temperature, high pressure, huge centrifugal force and wet steam area water drop erosion under extremely harsh working conditions, and plays a decisive influence on the safety and reliability of unit. With the improvement of China's forging technology, the development and use of blade forgings gradually mature, but because of the twisted shape of blade, complex, so its processing and manufacturing process is complex, difficult. Limited by equipment capacity, large blade forging is particularly difficult, and large blade cost is relatively high, and single-piece unqualified can easily cause great loss. Therefore, in order to ensure the safety and reliability of large blade production, a stable forging production process and its die are urgently needed to improve production efficiency and reduce scrap rate.

[0003] The conventional blade forging and pressing processing in the prior art is mainly processed by friction press, the equipment is expensive, and the input-output is not matched. We create, summarize the experience through wear and tear, and innovatively use die forging hammer to process blade. Qualified fuselage and anvil are needed for die forging hammer processing to prevent equipment damage caused by performance fatigue of fuselage. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of equipment fuselage and anvil device for blade forging processing, to solve the above problems.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model discloses a kind of equipment fuselage and anvil device for blade forging processing, including anvil and the two symmetrical machine bodies of installation at the top of the anvil, the inside of the machine body is cavity, process hole is set up on the outside of the machine body, the inner wall and outer wall of the machine body are equipped with rib plate, the thickness of the rib plate is 90-110mm.

[0007] Further, positioning hole is set up on the anvil and the machine body, the machine body is fixed on the anvil by positioning pin through positioning hole.

[0008] Further, the bottom of the machine body is slidably connected on the anvil, the bottom of the machine body is equipped with sliding slot, the top of the anvil is equipped with slide rail, the machine body is slidably connected on the slide rail by sliding slot.
