The studs and the blade surfaces in the shape form a stable T-shaped structure, and meanwhile, the studs on the two sides form an integral square frame through the connecting rod and the connecting end, so that the structural rigidity of the blade body shell is enhanced. After pouring, the extrusion force of molten steel is directly offset by the vertical stud part shell, so that the problem of blade profile deformation is solved.

Description

Large compressor blade capable of preventing bulging deformation

Technical Field

The utility model relates to an investment casting field specifically is a prevent large-scale compressor blade of bloated variant.

Background

The adjustable guide vane of the large-scale compressor is a stainless steel part and consists of a triangular vane body and a rotating rod. The length of the blades of different models is different, and the length of the large-sized blade can reach seven-eight-hundred millimeters. The large-scale compressor guide vane of a certain foreign enterprise is an imported blade that is formed by full processing, and the both sides of its triangle-shaped blade are the fitting surface, require that the profile tolerance of blade profile is not more than 0.5mm, because the blade is imported foreign full processing part, high in production cost, the cycle length, the enterprise urgently needs domestic production replacement part. Compared with a completely machined part, the part machined locally by investment casting can obviously reduce the production cost of the part. With the long blade, the blade body has the problem of bulging of the shell in the casting process, so that the blade is deformed. This is because the blade shell is a flat hollow shell and when subjected to the molten steel extrusion force, it is easily offset by the reaction force generated by the deformation. The casting temperature of the steel material is higher than that of the high-temperature alloy, so that the deformation is more obvious.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prevent large-scale compressor blade of bloated variant has solved current in the pouring process, and the shell bloated problem can appear in the blade body, causes the problem of blade deformation.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a prevent large-scale compressor blade of bloated variant, be triangular's blade body including the cross-section, the one end terminal surface fixed connection dwang of blade body, another terminal surface fixed connection link of blade body, the last muscle of founding of difference fixed connection of the terminal surface of dwang and link, it establishes the top at the blade body to go up the muscle, the bottom of blade body is equipped with down the muscle of founding, the both ends difference fixed connection dwang of lower muscle and the terminal surface of link.

Preferably, a plurality of rectangular upper connecting blocks are arranged between the upper vertical ribs and the top of the blade body, and a plurality of rectangular lower connecting blocks are arranged between the lower vertical ribs and the bottom of the blade body.

Preferably, the upper vertical rib and the lower vertical rib are obliquely arranged at the top and the bottom of the blade body.

Preferably, the number of the upper connecting blocks is consistent with that of the lower connecting blocks, the number of the upper connecting blocks is three, the upper connecting blocks are arranged at the top of the blade body at equal intervals, and the lower connecting blocks are arranged at the bottom of the blade body at equal intervals.

Preferably, the connecting end is in the shape of a regular hexagon, and the center of the connecting end is connected with one end of the blade body.

Through the technical scheme, the utility model discloses beneficial effect: the deformation-preventing vertical ribs intermittently connected with the surface of the blade profile are designed on two sides of the blade body, the upper ends of the vertical ribs are connected with the rotating rod, and the lower ends of the vertical ribs are provided with connecting ends connected with the blades. The studs and the blade surfaces in the shape form a stable T-shaped structure, and meanwhile, the studs on the two sides form an integral square frame through the connecting rod and the connecting end, so that the structural rigidity of the blade body shell is enhanced. After casting, the extrusion force of molten steel is directly counteracted by the vertical stud part shell, and the problem of blade profile deformation is solved.
