Description
Technical field
The present invention relates to casting manufacture fields, and in particular to a kind of wind power principal axis metal mold and casting system.
Background technique
The wind energy industry of China is adjusted by the fast development that strides greatly a few years ago, the macro-goal of industry development at present
Whole, development priority gradually turns to upgrading synergy from promotion scale and Push Technology progress comes up.High-power, high-performance and low cost
Wind power casting become the market demand direction.Key components and parts one of of the main shaft as wind power generating set, manufacturing method
It is using forging mostly, part material is forged steel, and since the price of forging is much higher than casting, domestic and international some complete-system vendors are just logical
It crosses and main shaft is changed to casting by forging to reduce cost.
The wind power principal axis founding materials of mainstream are common spheroidal graphite cast-iron EN-GJS-400-18-LT, process route at present
Shrinkage porosite problem for conventional sand casting, the main shaft of this method production is difficult to be fully solved, and cast structure is not fine and close enough,
Finished surface easily forms the defects of pin hole.Some high-end customers have the inherent quality of casting, dense structure's degree and material property
Higher requirement, this requires us constantly to explore high performance new material and new process, new material EN-GJS-
Therefore 500-14U(is brought into schedule referring to the gravity die casting process of the main shaft of European standard EN1560-2011).
Permanent mold casting is also known as diecasting, with intensity height, any surface finish, it is reusable the advantages that and it is extensive
It uses.The design of metal mold needs to consider three principal elements, first is that appropriate chill effect, to reduce the contracting of casting as far as possible
Pine tendency；Second is that the convenience of manufacture and use；Third is that meeting intensity requirement.In the prior art for reach above-mentioned requirements frequently with
Means be: according to workpiece size select metal mold wall thickness with meet intensity requirement, increase be arranged in external chill it is sharp to meet
Cold requirement etc..But from the point of view of actual casting effect, for heavy castings such as wind power principal axis, above-mentioned means can not be effectively eliminated
The shrinkage porosite problem of casting, and it is only capable of the position change that shrinkage porosite occurs.
It moreover has been found that there is more apparent slag inclusion always when carrying out large-scale workpiece casting using metal mold.Although
Surface defect caused by slag inclusion can be removed by subsequent machining, but serious slag inclusion problem requires workpiece to exist
Sufficient machining allowance must be reserved in design and casting process, and this will cause the waste and subsequent mechanical processing of founding materials
The complication of process, so as to cause the rising of cost.
Summary of the invention
To solve problems of the prior art, the present invention provides a kind of wind power principal axis metal mold and casting system.
Specifically, the present invention provides following scheme: a kind of wind power principal axis metal mold, including upper parting and lower parting, wherein
The upper parting is used to form the casting space of main shaft small end, and the lower parting is used to form the casting space of main shaft big end, institute
The complete casting space that assembling forms main shaft can be superimposed by stating parting and the lower parting；The metal mold has to be connected along axial direction
The wall thickness of continuous variation, and when the metal mold is held upright, on any cross section, the wall thickness of the metal mold with it is described
A definite value of the ratio of the wall thickness for the main shaft being cast between 0.5-1.5.
Preferably, the ratio is 1.1.
Preferably, the both ends of parting up and down of the metal mold are equipped with flange, and multiple bolts are provided on the flange
Hole；Wherein, it is contacted in the parting up and down and is respectively equipped at least two location holes on two flange, allowed for by using pin
Realize the location and installation of parting up and down；It is in contact at the inner edge of two flange in the parting up and down and further respectively has a parting
Groove and parting protrusion are to form ladder parting；Stop-off is additionally provided at the outer rim of two flange of the contact of parting up and down
Groove；The ladder parting is cooperateed with the stop-off groove, avoids the generation for penetrating case.It turns on at least top of the parting up and down
The outer rim on side is fixed with hanging axis, and four hanging axises are at least arranged on preferably each top flange.
Preferably, the parting groove is located in lower parting.
Preferably, the outer wall of the metal mold is equipped with stiffener plate, and the stiffener plate includes that several edges are axially disposed at
Vertical bar plate and several transverse bar plates being circumferentially located at.
The present invention also provides a kind of wind power principal axis casting systems comprising metal mold, mud core and running gate system above-mentioned；Institute
It states mud core to be located inside metal mold, and the two is coaxially disposed, and is formed between the outer surface of the mud core and the inner surface of metal mold
Casting type chamber；It is provided with arbor in the middle part of the mud core, the arbor can increase the intensity of mud core, while reduce its weight；Institute
It states and is wound with outlet rope on arbor to be vented for mud core；The running gate system includes sprue, socket, ingate and riser；
Wherein the sprue is arranged inside arbor, and the axially extending perforation mud core, the socket are located at the sprue
Bottom, and with the sprue be in fluid communication comprising positioned at lower part small diameter first-level buffer slot and it is superposed compared with
Major diameter level 2 buffering slot；It is preferred that the first-level buffer slot and level 2 buffering slot are circle；The ingate is located at mud core
Bottom, and it is connected to the level 2 buffering slot and the casting type chamber outer edge；The riser is located at the top of casting type chamber.
Preferably, the ingate is the multiple round tubes for being circumferentially positioned at the level 2 buffering slot outer rim.
Preferably, the ingate is batch seam, be circumferentially positioned at level 2 buffering slot periphery slit-shaped it is logical
Road.
Preferably, described batch seam be connected to casting outer edge, and connectivity part with buffer.
Preferably, the part that the mud core corresponds to upper parting has the diameter for being less than wind power principal axis design internal diameter, makes
It obtains wind power casting and obtains wall thickness more increased than design flow at this.It is such to design the feeding duration so that in Feeding channel
Extended, increase feeding amount, so that fabulous reduces shrinkage porosite phenomenon.It is described can be compared to the increased wall thickness of design flow
Later period passes through the removal of the means such as polishing.
Preferably, described to be gradually increased from the bottom to top compared to the increased wall thickness of design flow, meanwhile, the wind power principal axis exists
Wall thickness change at upper and lower parting has continuity.In other words, in the junction of the parting up and down, the increased wall thickness is
Zero.
The present invention compared with the prior art at least has the advantages that by being arranged to metal mold with changing with the shape
Wall thickness is effectively controlled the generation of casting main shaft casts shrinkage porosite problem；Metal mold is divided into parting up and down, so that it is manufactured, fortune
Defeated and inner wall brushing is more convenient, meanwhile, ladder parting is arranged in the inner wall in the parting junction up and down, and outer wall setting is mended
Sand groove, the two cooperation effectively reduce the probability for penetrating the appearance of case problem；Using batch seam channel connection socket and casting type chamber, have
Effect controls slag inclusion problem, and position restriction is occurred in the angular region R of main shaft；Innovation passes through increase main shaft top wall thickness
Mode so that shrinkage porosite has obtained further control.
