Abstract
A trough-type double-inclined-plane cold-bending side column connecting iron for a rail vehicle is suitable for a C70E-A type universal open wagon and comprises a base plate, wherein a first transition arc, an inclined plane plate, a second transition arc and a straight plate are sequentially and symmetrically arranged on two sides of the base plate; compared with the prior art, the utility model provides a be applicable to the general gondola car of C70E-A type cell type double inclined plane cold-formed side column even iron all has great promotion in reliability and security for the rail vehicle, can be long-term, effectual work.
Description
Technical Field
The utility model belongs to the technical field of railway freight car, concretely relates to cell type double inclined plane cold-formed side post even iron for rail vehicle.
Background
Rail transit is a fast and relatively low-cost traffic mode all the time, and along with the development of science and technology, the components of rail vehicles are changed continuously, and the performance requirements are gradually improved.
The defects of foaming, scabbing, folding, slag inclusion, section layering and the like cannot exist on the surface of a rail vehicle part due to actual needs, meanwhile, scratches and indentations cannot be formed, and stains cannot exist on the surface to keep consistent color and luster; the edge of the part cannot have the defects of flash, burr and the like, otherwise, the very serious potential safety hazard can be generated in the work process.
The groove type double-inclined-plane cold-bending side column connecting iron for the railway vehicle is one of the components of a C70E-A type universal open wagon, and is also an important component, and along with the continuous updating of standards, the original groove type double-inclined-plane cold-bending side column connecting iron for the railway vehicle cannot meet new requirements in performance and safety, so that the groove type double-inclined-plane cold-bending side column connecting iron for the railway vehicle is correspondingly redesigned, so that the safe, long-term and effective work becomes more urgent at present.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a two inclined plane cold-formed side post of cell type are iron even for rail vehicle is applicable to the general open wagon of C70E-A type, compares and all has great promotion in prior art at reliability and security.
A trough-type double-inclined-plane cold-bending side column connecting iron for a rail vehicle is suitable for a C70E-A type universal open wagon and comprises a base plate, wherein a first transition arc, an inclined plane plate, a second transition arc and a straight plate are sequentially and symmetrically arranged on two sides of the base plate;
the base plate, the first transition circular arc, the inclined plane plate, the second transition circular arc and the straight plate are integrally formed structures processed through rolling, the thickness of the integrally formed structures is 6mm, the straight plate is perpendicular to the base plate, and the radius of the first transition circular arc and the radius of the second transition circular arc are both 12 mm.
Further, the distance between the outer side edges of the two straight plates was 165 mm.
Further, the distance between the two ends of the substrate is 85 mm.
Adopt above-mentioned technical scheme the utility model discloses can bring following beneficial effect:
compared with the prior art, the utility model provides a be applicable to the general gondola car of C70E-A type cell type double inclined plane cold-formed side column even iron all has great promotion in reliability and security for the rail vehicle, can be long-term, effectual work.

In the figure, 1-base plate, 2-first transition arc, 3-inclined plane plate, 4-second transition arc and 5-straight plate.
Detailed Description
As shown in fig. 1-3, a channel type double-inclined-surface cold-bending side column connecting iron for rail vehicles is suitable for a C70E-A type universal open wagon, and is characterized in that: the device comprises a substrate 1, wherein a first transition arc 2, an inclined plane plate 3, a second transition arc 4 and a straight plate 5 are symmetrically arranged on two sides of the substrate 1 in sequence;
the base plate 1, the first transition arc 2, the inclined plane plate 3, the second transition arc 4 and the straight plate 5 are integrally formed structures which are processed by adopting a cold bending process in a rolling manner, and the integrated structure has the advantage of more reliable structure; the thickness of the integrally formed structure is 6mm, the whole structure is made of Q450NQR1 corrosion-resistant steel material which accords with the T/TB1979 standard, the total length of the groove type double-bevel cold-bending side column connecting iron for the railway vehicle is 5546mm, the bent angle part cannot be purely cracked after forming, the end head needs to be cut to be straight, no flash and burr exist, the torsion resistance per meter is not more than 1mm, the total torsion value in the total length range is not more than 5mm, the straightness per meter is not more than 1mm, and the total straightness in the total length range is not more than 5 mm;
the straight plate 5 and the substrate 1 are perpendicular to each other, and the radiuses of the first transition arc 2 and the second transition arc 4 are both 12 mm;
the distance between the outer sides of the two straight plates 5 is 165 mm.
The distance between the two ends of the substrate 1 is 85 mm.
The above description is only the preferred embodiment of the present invention, and is not a limitation of the present invention, and any person skilled in the art can replace and modify the equivalent made without departing from the present invention, which is considered as falling into the protection scope of the present invention.
