Abstract
The utility model discloses a novel roll holding box comprising a connecting portion and two end faces. The connecting portion is composed of two connecting columns and a half-cylinder face between the connecting columns. A transitional connecting piece is respectively arranged on each of the two sides of connecting parts of the connecting columns and the end faces. The front ends where the end faces are not connected with the connecting portion and are the same with axial starting positions of the transitional connecting piece are vertical rectangular planes, and cylindrical surfaces are formed between the vertical rectangular planes and the transitional connecting pieces. By the technical scheme, processing technique of the novel roll holding box is greatly simplified, and the amount of steel is saved.
Description
Technical field
The utility model relates to a kind of novel rolling and embraces case.
Background technology
Rolling and embracing case is the vital parts of locomotive co-relation bogie truck traffic safety.Of the prior art rolling embraced case foundry goods hypertrophy, and rolling newspaper case both ends of the surface inboard is trapezium structure, and each inclined-plane of trapezium structure can only carry out Milling Process by numerically-controlled machine tool, and processing capacity is huge, seriously prolongs the production cycle of this product.And be provided with bigger external subsidy in both ends of the surface during casting, after the blank moulding, the two ends outside face need process to guarantee dimensional accuracy.The Milling Process amount is huge, the processing technology complexity, and work efficiency is lower, causes the production cycle longer, has a strong impact on the locomotive manufacturing schedule.
Summary of the invention
The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, provide a kind of and be easy to processing, and novel the rolling that can save cost is embraced a case.In order to address the above problem, the utility model adopts following technical scheme:
A kind of novel rolling embraced case, comprises connecting portion and two end faces, and the semi-cylindrical between connecting portion is reached by two joint pins is formed, and joint pin both ends and end face connecting bridge both sides are provided with the transition contiguous block; Two end face inboards link to each other with connecting portion, the part front end identical with the transition block axial home position is vertical rectangular surfaces, are the faces of cylinder between vertical rectangular surfaces and the transition contiguous block.
Said structure has been cancelled the machinework requirement that tradition is rolled the non-rotating Milling Process face of embracing case both ends of the surface trapezium structure, has simplified processing technology greatly.
In addition, two faces of cylinder that are connected with vertical rectangular surfaces are symmetry up and down, and described transition contiguous block is symmetrical in twos with respect to the joint pin end.
The design of employing the utility model need not arrange external fan-shaped rising head subsidy in foundry technology process, change the inner circular aperture place into and establish blind riser to guarantee castability, directly cast out outer surface by model, external cylindrical surface direct casting in two ends has been simplified processing technology, has saved steel using amount.
Description of drawings
Fig. 1 rolls for tradition of the prior art and embraces the case design diagram.
Fig. 2 embraces the case design diagram for of the present utility model rolling.
Among the figure: 1. joint pin, 2 transition contiguous blocks, the 3. face of cylinder, 4. vertically rectangular surfaces, 5. rectangular surfaces, 6. semi-cylindrical.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Fig. 1 rolls for tradition of the prior art and embraces the case design, comprises connecting portion and both ends of the surface, and as can be seen from the figure, the semi-cylindrical 6 between connecting portion is reached by two joint pins 1 is formed, and along the circumferential direction draw at the cylinder two ends, forms end face.For explaining conveniently.Now the end face with the left side among Fig. 1 and the right is called left side and right side respectively.
Left side, two edges, joint pin 1 end circumferencial direction is provided with transition contiguous block 2, and the good linking of realization and left side.
Left side l is not connected with connecting portion, and the part identical with transition block 2 axial home position is trapezoid body: front end is vertical rectangular surfaces 4, vertically rectangular surfaces 4 with between transition is connected 2 be also rectangular surfaces 5, vertical rectangular surfaces 4 vertical planes are connected by the level and smooth face of cylinder with upper and lower rectangular surfaces 5.Two rectangular surfaces are corresponding up and down.
The inboard of the part that do not link to each other with connector in the right side also is trapezoid body, and difference is not have the joint pin end not have transition contiguous block 2.
The rectangular surfaces up and down 5 of trapezoid body recited above is non-rotating Milling Process face, in foundry technique, need the bigger fan-shaped rising head subsidy of both ends of the surface setting, after the blank moulding, rectangular surfaces 5 need process to guarantee dimensional accuracy up and down, expending great deal of steel causes, and whole to roll the overhours of embracing case elongated, the cost height, and efficient is low.
In order to address this problem, to the utility model proposes a kind of novel rolling and embrace case, as shown in Figure 2.Its difference with the prior art is: joint pin both ends and end face connecting bridge both sides are equipped with transition contiguous block 2, two continuous and identical with the transition block axial home position with connecting portion part front ends of end face body are vertical rectangular surfaces 4, are the faces of cylinder 3 between rectangular surfaces and the transition contiguous block 2 vertically.In other words, will have now exactly and roll trapezoid body rectangular surfaces 5 cancellations up and down of embracing the case both ends of the surface, relevant fitted position will be adjusted, form the face of cylinder 3.
The height of body diameter and vertical tangent plane all arranges according to the accessory actual conditions.
The utility model benefit of design like this is to have cancelled the machinework requirement of the non-rotating Milling Process face of both ends of the surface; Cancellation arranges fan-shaped rising head subsidy in the foundry technique, changes the inner circular aperture place into and establishes blind riser to guarantee castability, directly casts out outer surface by model, the direct casting of two ends external cylindrical surface.
By this kind improvement, avoided a large amount of angular milling manufacturing procedures, avoid the external casting subsidy of large tracts of land, thereby simplified technology, save steel using amount, enhance productivity.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
