Description
Technical field
The utility model relates to core and makes the field, is a kind of railway freight-car bolster integral core sample specifically.
Background technology
Railway freight-car generally partly is made up of car body, bogie, brake apparatus, coupler and draft gear etc.The effect of bogie is a supporting body, and guided vehicle is along rail running, and bears the various load from car body and circuit.The bogie of tradition lorry mainly is made up of three parts bogie side frame, bolster, wheel, and wherein, bolster, bogie side frame are the important load bearing component of railway freight-car, needs to adopt cast steel, with forging type production.Bolster has some inner chambers and endoporus, constructs very complicatedly, therefore, need settle core to form inner chamber during casting in the casting mold die cavity.
At present, the production technology of producing high speed, bolster that heavy-duty freight car uses is core assembling technology, the core that is about to form the bolster inner chamber is divided into a plurality of parts, at first makes core when producing, and in the casting mold die cavity core is combined to form the inner chamber of foundry goods then.The advantage of this mode is that technology is fairly simple, is convenient to manual operations, but the defective that also exists some to be difficult to overcome is summarized as follows:
On the one hand, the segmentation position of these cores is in the edge at the important force part of product or this position, if misoperation or frock wearing and tearing, to cause foundry goods fash to occur, under the fatigue stress effect in casting stress in process of production or the utilization process, may produce the defective of fire check or fatigue crack at this position; On the other hand,, be difficult in process of production finding, in product utilization process, easily rupture at these defective locations because these core segmentations all are in product cavity; The reason of this two aspect all will influence the lorry security of operation, can't adapt to the needs that railway transportation constantly develops to high-speed overload.In addition, owing to adopt manual operations, there is artificial factor in it, is prone to the inaccurate problem of core split fix.
The problems referred to above can solve by integral core technology, and this technology is designed to two cores up and down with the bolster inner chamber, combines the formation integral core then.Because eliminated the defective of core segmentation, this integral core can significantly reduce the operating security incident of railway freight-car.
Obviously, in order to produce railway freight-car bolster integral core, must the corresponding railway freight-car bolster integral core sample of design.
The utility model content
In view of this, the utility model provides a kind of railway freight-car bolster integral core sample, can be suitable for the production needs of railway freight-car bolster integral core.
For solving above technical problem, the railway freight-car bolster integral core sample that the utility model provides is made up of last apperance and following apperance; The described apperance that goes up comprises that core box on, some loose pieces of going up reach upward box core loose piece fixture, and described apperance down comprises core box, some loose pieces down; Describedly go up the roughly corresponding integral core outer surface profile of inner chamber profile that core box and following core box form, described go up core box and following core box with the largest contours place of process integral core and broken line that main body is level as a minute box face; Described go up loose piece, down loose piece corresponding described respectively go up core box, down influences such as the projection of core box outside described minute box face, inclined-plane described on core box, the position setting that separates with described integral core of core box down; Described upward loose piece, following loose piece specifically comprise:
First kind loose piece, the projection setting on corresponding next-door neighbour's integral core length direction line of symmetry, described each first kind loose piece is provided with boss to the inside, near the low-lying part of the corresponding integral core surface of this boss length direction line of symmetry;
The second class loose piece, the corresponding inclined-plane setting of below to the inside near two symmetrical waists on the integral core length direction, described each second class loose piece has the inclined-plane of below to the inside of corresponding described integral core waist towards a side of inner chamber.
Preferably, described loose piece on each, down loose piece with describedly go up core box, install in the mode of coming off entirely between the core box down, make finish after the coremaking described each go up loose piece, loose piece can freely take off on described upward core box, following core box down.
Preferably, described on each box core loose piece fixture be steady pin, be used under the frock state with described on each loose piece be fixed on described on core box.
Preferably, the described apperance that goes up also comprises upper plate, is used for core box on placement under the frock state is described; Described apperance down also comprises lower shoe, is used for placing under the frock state described core box down.
Preferably, described upward core box, following core box are fixed on described upper plate, the lower shoe by alignment pin respectively.
Preferably, under the frock state, describedly go up core box to close core with described core box down be one by closing core machine upset back.
Preferably, also comprise the core box clamp mechanism, be used for described core box, the following core box gone up after core is closed in clamping.
Compared with prior art, the utility model provides railway freight-car bolster integral core sample, to greatest extent bolster is done as a whole consideration, can disposable acquisition bolster integral core, thus eliminate the defective of segmentation core assembly.The utility model can not produce the assembly error between two labels by whole core assembly, can finish the production operation of integral core in high quality; Simultaneously, owing to need not manual group, can improve the production efficiency of integral core to, polishing.The production of the applicable railway freight-car bolster integral of the utility model core needs, and it both had been suitable for professional small lot batch manufacture casting bolster, also can be equipped with other mo(u)lding equipment and form the mechanization moulding production line.
