Abstract
The utility model relates to a core head support for a mud core of a whole wind power machine. The core head support comprises a core bone, a core head support and a box outer mould support, wherein the core bone is arranged in the mud core; the core head support is arranged in the mud core and one end of the core head support is connected with the bone core; the box outer mould support is arranged in an outer mould; one end of the box outer mould support is connected with the other end of the core head support; and the other end of the box outer mould support is connected with a box gear. According to the core head support disclosed by the utility model, the core bone is placed in the mud core so that the strength of the mud core is improved and the shape and the size of the mud core are guaranteed. Meanwhile, the core head support is pre-buried in the mud core so that the strength of the mud core is greatly increased; the box outer mould support is pre-buried in the lower box outer mould so that the compressive strength of sand mud is greatly improved and the problem of sinking caused by the factor that the mud core is too heavy is effectively solved; and meanwhile, the strength of the sand box is satisfied and the mud core is prevented from floating up after pouring, the fixation and the positioning of the mud core are realized, and the shape and the size of an inner cavity of a casting are guaranteed.
Description
Technical field
The utility model relates to the complete blower field, and particularly a kind of core print for wind-powered electricity generation complete machine mud core supports.
Background technology
Along with the wind-powered electricity generation complete machine develops towards maximization, high-power direction, wind-powered electricity generation is increasing with nodular iron castings such as wheel hub, bases, requires also more and more higher.The overall size of 5MW base reaches 5.8 meters * 5.4 meters * 4.8 meters, and poured weights reaches 88 tons, and casting dimension is big, Heavy Weight.The mud core is the important assurance of core cavity shape and size, and the mud core that this base uses is complex-shaped, bulky, and the weight of single mud core is above 60 tons.During following core, if will fix and locate more than 60 ton the mud core of weighing, the core print size need be done very big, but limited by sandbox, unsuitable excessive amplification core print size.Depend merely on the sand mud and can't bear its weight, damage sand mold easily by pressure, cause that the mud core sinks; After cast, the buoyancy of molten metal is very big equally, also can cause the come-up of mud core, causes the casting dimension distortion.
For little mud core, for strengthening the permissible compression stress of casting mold, generally adopt the compression strength of measures raising core print seats such as additional core, iron plate, refractory brick in core print seat.But for the mud core of the ton that weighs surplus in the of 60, depending merely on top measure can't meet the demands, and as not taking the necessary measures, the sand mud can be damaged by pressure, and damaging all can appear in mud core and core print seat, causes that the mud core sinks.
The utility model content
The utility model provides a kind of raising mud core intensity, guarantees the shape and size of mud core, has realized that the core print that is used for wind-powered electricity generation complete machine mud core of the fixing and location of mud core supports.
For solving the problems of the technologies described above, the core print that the utility model is used for wind-powered electricity generation complete machine mud core supports, and comprising: arbor, described arbor are arranged in the mud core; Core print supports, and described core print supports and is arranged in the mud core, and the end that described core print supports is connected with described arbor; And the support of case external mold, described case external mold supports and is arranged in the external mold, and the end that described case external mold supports is connected with the other end that described core print supports, and the other end that described case external mold supports is connected with the case shelves.
Preferred described arbor, the center line that described core print supports, described case external mold supports about the mud core are the minute surface symmetry.The material that described core print supports and described case external mold supports is iron.
The core print that the utility model is used for wind-powered electricity generation complete machine mud core is supported on the mud core and places arbor, improves mud core intensity, guarantees the shape and size of mud core.Simultaneously pre-buried core print supports in the mud core, and this supports an end and directly links to each other with arbor, and the other end links to each other with pre-buried case external mold support in the external mold, has increased the intensity of mud core greatly; The provided box external mold supports in the nowel external mold, this supports upwards direct and core print support and connection, directly be connected with the case shelves of nowel downwards, support to bear the weight of whole mud core by the provided box external mold, improve the compression strength of sand mud greatly, effectively solved the overweight sinking problem that causes of mud core; The provided box external mold supports in top box equally, this supports direct and core print support and connection downwards, upwards directly be connected with the case shelves of top box, put more than 100 ton the foundary weight of weighing above the top box, both satisfied the intensity of sandbox, avoid the come-up of cast back mud core again, realized fixing and the location of mud core, guaranteed the shape and size of core cavity.

The specific embodiment
Below in conjunction with accompanying drawing the core print support that the utility model is used for wind-powered electricity generation complete machine mud core is described in further detail.
As shown in Figure 1, the core print that the utility model is used for wind-powered electricity generation complete machine mud core supports, and comprising: arbor 2, arbor 2 are arranged in the mud core 1; The core print of irony supports 3, and core print supports 3 and is arranged in the mud core 1, and an end of core print support 3 is connected with arbor 2; And the case external mold of irony support 4, the case external mold supports 4 and is arranged in the external mold, and an end of case external mold support 4 is connected with an other end of core print support 3, and an other end of case external mold support 4 is connected with case shelves 5.Arbor 2, core print support 3, case external mold support 4 center lines about mud core 1 and are the minute surface symmetry.
The core print that the utility model is used for wind-powered electricity generation complete machine mud core is supported on the mud core and places arbor, improves mud core intensity, guarantees the shape and size of mud core.Simultaneously pre-buried core print supports in the mud core, and this supports an end and directly links to each other with arbor, and the other end links to each other with pre-buried case external mold support in the external mold, has increased the intensity of mud core greatly; The provided box external mold supports in the nowel external mold, this supports upwards direct and core print support and connection, directly be connected with the case shelves of nowel downwards, support to bear the weight of whole mud core by the provided box external mold, improve the compression strength of sand mud greatly, effectively solved the overweight sinking problem that causes of mud core; The provided box external mold supports in top box equally, this supports direct and core print support and connection downwards, upwards directly be connected with the case shelves of top box, put more than 100 ton the foundary weight of weighing above the top box, both satisfied the intensity of sandbox, avoid the come-up of cast back mud core again, realized fixing and the location of mud core, guaranteed the shape and size of core cavity.
Below the preferred embodiment of the utility model having been created specifies, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
