Abstract
The utility model relates to a crossbar type bogie bolster sand core used for wagons, which comprises a fish abdominal cavity structure below a centre plate surface, a reducing hole structure, a drain hole structure, a pull rod hole structure, a splayed surface cavity structure and an end structure, and is characterized in that the fish abdominal cavity structure below a centre plate surface, the reducing hole structure, the pull rod hole structure, the splayed surface cavity structure and the end structure are integrally moulded into an integrative sand core. The crossbar type bogie bolster sand core has a smooth surface and is capable of effectively avoiding the casting flashes and fins caused by the use of diverse combined sand cores, so that the internal quality of a cast is improved and the working strength is reduced.
Description
Technical field
The utility model relates to railway freight-car with intersecting rod-type truck bolster core production field.
Background technology
Bolster is the railway freight-car important spare part, is the thin-walled shell construction, and material is a low-alloy steel.In the railway goods train bogie design, bolster and bolster are main component part, also are main stressed parts, and railway freight-car is in service under different situations, and bolster must sustain various tests.
Along with the China railways lorry develops to the high-speed overload direction; Require higher to important spare part product quality such as bolster and combination property; Therefore; Be railway freight-car development need after satisfying, must improve product quality, the combination property of important spare parts such as bolster, thereby guarantee railway freight-car high-speed overload reliability of operation, security.
Railway freight-car all adopts core as die casting production with bolster both at home and abroad.At present, railway freight-car bolster core all adopts split core casting technique both at home and abroad, that is, each core part is made core box respectively, subsequently each core core box is combined.Like this, the core and the core junction of bolster inner chamber each several part are prone to casting flaws such as fash, crackle, sand holes, increase later stage housekeeping amount, reduce production efficiency, reduce product quality, bring potential safety hazard.Casting flaws such as fash, crackle, sand holes perplex bolster manufacturing enterprise always, therefore, are necessary existing bolster core is improved.
Summary of the invention
The utility model technical problem to be solved is the deficiency that has a kind of bolster foundry engieering now in order to overcome, and a kind of intersection rod-type truck bolster core is provided, and effectively improves bolster product quality and combination property.
For solving the problems of the technologies described above; The present invention provides a kind of intersection rod-type truck bolster core; It is characterized in that; Comprise fish belly inner-cavity structure, leaking hole structure, lightening core structure, tie rod hole structure, Eight characters face inner-cavity structure and end construction under the cartridge face, the integral sand core of the fish belly inner-cavity structure under the said cartridge face, leaking hole structure, lightening core structure, tie rod hole structure, Eight characters face inner-cavity structure and the integrated moulding of end construction.
The integrated global formation structure of the utility model; The core smooth surface; Avoided using diversification to make up casting overlap, fash that core brings, the core cavity smooth surface is smooth-going, reduces core cavity surface burning into sand, pore, crack defect significantly; Alleviate the casting cleaning working strength, improve casting quality.
Description of drawings
Further specify below in conjunction with accompanying drawing and the specific embodiment technical scheme the utility model.
Fig. 1 is the structural representation of the bolster integral core of the utility model.
The specific embodiment
The utility model bolster integral core is as shown in Figure 1, and the fish belly core 6 under the cartridge face 8, last leaking hole 7, following leaking hole 3, lightening core core 4, tie rod hole core 5, end core 1, Eight characters facing sand core 2 are linked to be bolster integral core of formation.Avoid being connected each other of a plurality of split cores of prior art, caused product casting flaws such as fash, crackle, sand holes to occur.
In order further to support the bolster core of the described global formation of claims; The integral forming method of bolster integral core is below described; May further comprise the steps: at first, require to make the integral core core box that comprises fish belly inner-cavity structure, leaking hole structure, lightening core structure, tie rod hole structure, Eight characters face inner-cavity structure and end construction according to the bolster casting technique.
Then, the integral core core box is cooperated with core shooter, external chill, chromite sand and the arbor that plays booster action are positioned in the core box up and down thickness greater than the place, part of average thickness.
Again, carry out matched moulds, add sand, penetrate sand, sclerosis, die sinking, plunger tip, the core overall time penetrated makes.Core shooter adopts the triethylamine hardening resin sand.
At last, carry out the integral core surface treatment by manual work, processing comprises whole inspection, detail sanding.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
