Abstract
The utility model discloses a kind of combined type carriage bottom plates, it is placed between front end-plate and end plate with protrusion, including front end-plate, end plate and middle plate, the middle plate at equal intervals, the leading portion plate and end plate are fixed together by welding manner and middle plate, and the middle plate is obtained by roll-forming.Knockdown carriage bottom plate meets the needs of various different length railway carriages by the middle plate of front end-plate, end plate and roll-forming, keeps process structure simple, it is easy to accomplish and processing, reduce difficulty of processing, saves processing cost.
Description
Technical field
The utility model is related to microcaloire vehicle box structure field, especially a kind of combined type carriage bottom plate.
Background technology
The producer of domestic production microcaloire railway carriage takes entirety to strike out pattern corrugation bottom plate, since each vehicle railway carriage is long more
Degree size differs, so each carriage bottom plate length is different.In order to meet each vehicle length dimension, it is necessary to which parts supply
Quotient is answered to provide the various carriage bottom plates that length dimension differs.Carriage bottom plate during punching production, belong to single-machine capacity it is big, at
Type is difficult, manufactures and designs period relatively long stamping parts product.Meanwhile during punch forming, stock utilization is opposite
Relatively low, waste of material is serious.
It is a kind of microcaloire carriage bottom plate of the prior art as shown in Figure 1, longer sides length dimension is L, is needed according to difference
The size of microcaloire vehicle requires to formulate corresponding mold, carries out punch forming, high per sleeve forming mould Costco Wholesale, and is wanted using equipment
Reach 1500T or more, the development cycle needs 90 days or so, and rear its will also increase the tooling devices such as trimming.
Utility model content
The purpose of this utility model is that by a kind of knockdown carriage bottom plate, realize that the plate under different body lengths is long
Demand reduces difficulty of processing and saves processing cost.
A kind of combined type carriage bottom plate, at equal intervals with protrusion, including front end-plate, end plate and middle plate, the middle plate
It is placed between front end-plate and end plate, the front end-plate and end plate are fixed together by welding manner and middle plate, in described
Plate is obtained by roll-forming.
Preferably, crossbeam is fixed with by connector below the middle plate, crossbeam is distributed at equal intervals below middle plate.
Preferably, the crossbeam and protrusion are spatially vertical.
Preferably, the front end-plate and end plate use punch forming, stamping equipment 400T.
The beneficial effects of the utility model are：Knockdown carriage bottom plate passes through front end-plate, end plate and roll-forming
Middle plate meets the needs of various different length railway carriages, keeps process structure simple, it is easy to accomplish and processing, reduce difficulty of processing, section
Save processing cost.
Description of the drawings
Fig. 1 is a kind of existing microcaloire carriage bottom plate；
Fig. 2 is combined type carriage bottom plate structural schematic diagram；
Fig. 3 front end-plate bottom substance schematic diagrams.
In figure：Plate in 1,2 front end-plates, 3 end plates, 4 crossbeams, 5 connectors, 10 protrusions.
Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing attached drawing and reality
It applies example and illustrates specific embodiment of the present utility model.
Embodiment one
Such as a kind of Fig. 2-combined type carriage bottom plates shown in Fig. 3, protrusion 10, including front end-plate 2, rear end are carried at equal intervals
Plate 3 and middle plate 1, middle plate 1 are placed between front end-plate 2 and end plate 3, and front end-plate 2 and end plate 3 pass through welding manner and middle plate 1
It is fixed together, middle plate 1 carries out roll-forming by 75KW rolling equipments and obtains, and front end-plate 2 and end plate 3 are used and struck out
Type, stamping equipment 400T, can be used forcing press.
Wherein, 1 lower section of middle plate is fixed with crossbeam 4 by connector 5, and crossbeam 4 is distributed in 1 lower section of middle plate at equal intervals, horizontal
Beam 4 and protrusion 10 are spatially vertical.
The above descriptions are merely exemplary embodiments of the present utility model, is not limited to the model of the utility model
It encloses.Any those skilled in the art, made equivalent change under the premise of not departing from the design and principle of the utility model
Change and change, the range of the utility model protection should all be belonged to.
