Description
Technical field
The present invention relates to a kind of railway freight-car roof hood, in particular to the whole vertical paving roof of a kind of railway freight-car and its
Manufacturing method.
Background technique
The roof of railway freight-car is usually plate shell and camber beam welding structure, due to being limited by steel plate width, present roof
Plate shell be welded by the muti-piece board group being laterally arranged, since plate shell steel plate is relatively thin, weld seam is more, so the big weldering of welding workload
It stitches quality to be not easy to guarantee, the roof of the car transport vehicle in lorry is exactly this structure, since roof panels shell is sheet metal cross
To composite structure, and car body is longer, seam is more, so complex manufacturing technology, production efficiency are low.Therefore the vehicle of this structure
Top either riveted structure, welding structure in seam crossing are easy to appear quality problems, when problem is serious due to roof leak and
Cause to transport loss of goods.Currently, the roof seepy question of the car transport vehicle in railway freight-car is still to need thoroughly solution
Technical problem certainly.
Summary of the invention
In view of the above-mentioned problems, a kind of simple the object of the present invention is to provide structure and leakproof railway freight-car indulges paving with whole
Roof and its manufacturing method.
To achieve the above object, the invention adopts the following technical scheme: a kind of whole vertical paving roof of railway freight-car, special
Sign is: including the first plate-like side width and second side width, first side width and second side width include level board,
The the second angle facade connected with level board first end inclination and the first folder being connect vertically with the second angle facade
The second end of level board described in angle facade, first side width and second side width is bent into back hook-shape structure, and two
A hook-shape structure that returns forms back hook type nesting, and in first side width, closely described return at hook-shape structure is provided with for fixed
The protrusion of the semi arch of position.
The first angle facade in first side width and second side width is arranged in the protrusion of semi arch
Middle plane in.
A kind of railway freight-car manufacturing method of whole vertical paving roof, includes the following steps, it is characterised in that:
1) railway freight-car production line of whole vertical paving roof, the production of the whole vertical paving roof of railway freight-car are assembled
Line includes that the uncoiling leveling apparatus set gradually from front to back, saddle joint multi-roll mill, seaming swaging multi-roll mill, facade are more
Roller mill, inclined-plane multi-roll mill, roof cutting machine and carrying roller line；
2) uncoiling leveling apparatus, and opening in the first roll bending are provided in the first roll bending of fixed width width and the second roll bending
The lower section of the second roll bending is arranged in volume leveling apparatus, and the roll bending in the first roll bending and the second roll bending is after the smoothing of uncoiling leveling apparatus
Become the first side width and second side width；
3) the first side width extrudes seaming stile by saddle joint multi-roll mill, and second side width is rolled by saddle joint multiple roll
Machine extrudes seaming back hook shape；
4) second side width and the first side width are merged in into same plane before seaming swaging multi-roll mill, and in second side width
Seaming stile be located in the seaming back hook shape in the first side width, seaming stile and seaming are returned using seaming swaging multi-roll mill
Hook-type flattens on the first side width, and it is nested that the first side width and the second end of second side width form stable back hook type, utilizes simultaneously
Seaming swaging multi-roll mill suppresses the protrusion of semi arch on the first side width；
5) facade multi-roll mill suppresses the first angle facade with protrusion positioning on the first side width and second side width；
6) inclined-plane multi-roll mill is with protrusion positioning, on the first side width and second side width for having suppressed the first angle facade
Re-compacted second angle facade out；
7) the vertical paving roof of the single entirety for being cut off roof structure using roof cutting machine is moved ahead on carrying roller line.
The invention adopts the above technical scheme, which has the following advantages: 1, the first side width and second side width of the invention
Second end be connected as one by returning the mutually nested form of hook-shape structure, welded seam bring welding deformation can be eliminated
Equal technological problems are convenient for production line manufacture, prevent leakage accident, guarantee manufacturing quality.2, time hook-shape structure of the invention
Lower plane be planar structure, in order to which inner wall and carline are bonded.3, the present invention closely back hook shape knot on the first side width
The place of structure is provided with the protrusion of semi arch used for positioning, and its first angle facade in the first side width and second side width
Middle plane in, therefore the present invention can not only prevent seaming from loosening, but also can be used as the rolling centre of location, prevent in the operation of rolling
It deviates.4, the production line of the whole vertical paving roof of railway freight-car of the present invention is using uncoiling leveling apparatus by the first roll bending and the
Two roll bendings become the first side width and second side width, are pressed respectively on the first roll bending and the second roll bending using saddle joint multi-roll mill
Seaming stile and seaming back hook shape out are flattened seaming stile and seaming back hook shape in the first side using seaming swaging multi-roll mill
It is nested that stable back hook type is formed on width, suppresses the first angle facade respectively using facade multi-roll mill and inclined-plane multi-roll mill
With the second angle facade, roof structure is cut off finally by roof cutting machine to obtain the vertical paving roof of single entirety, therefore raw
First roll bending and the second roll bending can be directly made as finished product by producing line, and technique is advanced, high degree of automation, thus production efficiency compared with
Height, lower production costs.5, the first side width of the invention is in the lower section of second side width, and seaming stile is on the first side width, seaming
Back hook shape on second side width, arrange up and down to facilitate seaming position to fasten by seaming stile and seaming back hook shape, becomes in seaming
Shape rolling is carried out after one again, makes the design and manufacture that seaming joint technology is simple, facilitates roll mill.
