Abstract
The utility model discloses a large-sized cylindrical casting with an elliptic deformation preventing function. The large-sized cylindrical casting comprises a casting body (1) which is a large-sized cylindrical casting. A straight barrel (2) is arranged on the large-sized cylindrical casting body (1), and a group of annular cast ribs (4) are arranged on the inner wall of the straight barrel (2). According to the large-sized cylindrical casting, the outer diameter of a straight barrel of a shell of a 97 motor can be controlled to range from 844.5mm to 845mm, and the ellipticity error is 0.5mm. Being very good in size, the casting completely meets requirements for the ellipticity of 2mm of customers, and ensures that product development finishes on time. The annular cast ribs can very efficiently prevent rotating body type castings (namely, barrel body type castings) from deforming, and the large-sized cylindrical casting has high popularization value.
Description
Technical field
The utility model relates to a kind of large-scale tubular foundry goods that prevents ovalizing deflection, belongs to the casting technology field of large-scale cylindrical part.
Background technology
97 electric machine casings are vital parts on the American Electric Power locomotive engine, and traffic safety is played an important role.On the electric machine casing foundry goods, local thermal center is more, and in the cooling procedure after casting pouring, each position stress is different, causes casting deformation.Particularly electric machine casing foundry goods one end is straight cylinder, belongs to large-scale tubular casting body, and the barrel of straight cylinder is provided with long rectangular window, causes this position weaker, greatly reduces the stability of vertical cylinder part, the distortion that has strengthened vertical cylinder part.The height of cylindrical portions is 346mm, and the processing request of cylindrical portions external diameter is 844 ± 4mm.
Present casting method is directly by the size molding of electric machine casing, to cast, there is gross distortion in the electric machine casing foundry goods of casting out, vertical cylinder part particularly, the bore of straight cylinder is ellipticity, major axis 850mm, minor axis 835mm, size differs 15mm, differ too large with the 2mm of customer requirement, do not meet processing request.
Summary of the invention
The purpose of this utility model is, a kind of large-scale tubular foundry goods that prevents ovalizing deflection is provided, and can guarantee the ovality requirement of large-scale tubular foundry goods straight cylinder bore, to overcome the deficiencies in the prior art.
The technical solution of the utility model:
Of the present utility modelly a kind ofly prevent that the large-scale tubular foundry goods of ovalizing deflection is, comprise foundry goods, this foundry goods is large-scale tubular foundry goods, is provided with straight cylinder on the foundry goods of large-scale tubular; The inwall of straight cylinder is provided with one group of annular casting muscle.
The bore of above-mentioned straight cylinder is 500～1000mm.
Have at least the end face of an annular casting muscle concordant with the nozzle of the straight cylinder of foundry goods in above-mentioned one group of annular casting muscle.
The width W of above-mentioned annular casting muscle is 40～60mm, and thickness δ is 10～20mm.
The width W of above-mentioned annular casting muscle is 50mm, and thickness δ is 15mm.
Compared with prior art, adopt the vertical cylinder part distortion of large-scale tubular foundry goods of the present utility model very little, casting dimension is very good, meets customer requirement fully and ensures that product development finishes on schedule.It is very simple that the utility model implements, and only needs the endless belt that increases by a required size at the mould corresponding position to get final product.Be specially adapted to the casting processing of rotary type foundry goods (cylindrical shell class foundry goods), have higher promotional value.

Fig. 2 is the three-dimensional view of Fig. 1;
Fig. 3 is 97 electric machine casings after annular casting muscle of lathing;
Fig. 4 is the three-dimensional view of Fig. 3.
Being labeled as in accompanying drawing: 1-foundry goods, 2-straight cylinder, 3-rectangular window, 4-annular casting muscle.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
Embodiment of the present utility model: the utility model is that a kind of to prevent that large-scale tubular foundry goods from producing the method for ovalizing deflection constructed according to following, as depicted in figs. 1 and 2, the method is the one group of annular casting muscle of inwall top casting at the nozzle of the straight cylinder of large-scale tubular foundry goods, the stability of casting muscle by annular prevents that large-scale tubular foundry goods from producing ovalizing deflection, to meet the casting requirement of large-scale tubular foundry goods.The bore of described large-scale tubular foundry goods is 500～1000mm.Described one group of annular casting muscle comprises at least one annular casting muscle, and the end face of one of them annular casting muscle is concordant with the nozzle of the straight cylinder of large-scale tubular foundry goods.The width W of annular casting muscle is controlled between 40～60mm, and thickness δ is controlled between 10～20mm.The width W of annular casting muscle is preferably 50mm, and thickness δ is preferably 15mm.
Constructed according to said method of the present utility model a kind ofly prevent that the large-scale tubular foundry goods of ovalizing deflection is, as depicted in figs. 1 and 2, comprise foundry goods 1, foundry goods 1 be shaped as straight cylinder 2; The nozzle inwall of straight cylinder 2 is provided with annular casting muscle 4.The bore of described straight cylinder 2 is 500～1000mm.Have at least the end face of an annular casting muscle 4 concordant with the nozzle of the straight cylinder 2 of foundry goods 1 in 2 described one group of annular casting muscle 4.The width W of annular casting muscle 4 is 40～60mm, is preferably 50 mm.The thickness δ of annular casting muscle 4 is 10～20mm, is preferably 15 mm.
Embodiment, use 97 electric machine casings as example.97 electric machine casing one ends are straight cylinder, and this straight cylinder height is 346mm, and external diameter is 844 ± 4mm, belong to large-scale tubular foundry goods.
During concrete enforcement, the straight cylinder of 97 electric machine casing one ends is in the bottom of mould, and mould can adopt wood mold coupled, also can adopt metal die.Only needing to increase a width at the mould corresponding position is 50mm, and thickness is that the endless belt of 15mm gets final product.
After completing foundry goods casting, foundry goods can be clamped on lathe, during with casting in order to prevent that the annular casting muscle 4 that ovalizing deflection is set up from machining away.97 electric machine casings 1 that process as shown in Figure 3 and Figure 4.
Principle of the present utility model
Utilize the radial stability of annular object, annular casting muscle is set in the end of foundry goods vertical cylinder part, cast by annular the vertical cylinder part that muscle prevents foundry goods and produce radial deformation in casting cycle.Annular casting muscle on foundry goods machines away in post-production, namely guaranteed casting dimension, simultaneously the overall appearance quality of foundry goods is not affected yet.After adopting method of the present utility model, the straight cylinder external diameter of 97 electric machine casing one ends can be controlled between 844.5～845mm, and ellipticity error is 0.5mm.As seen annular casting muscle is very effective to the distortion that prevents rotary type foundry goods (cylindrical shell class foundry goods).
