The utility model light feature and multiple groups abnormity ripple struction support strength using stainless sheet steel intensity height
High characteristic, product have the characteristics that structure is excellent, intensity is high, light-weight, assembly technology is simple, the service life is long, enhance subway
The structural strength of bottom frame floor can be widely applied to subway vehicle undercarriage manufacture.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
A kind of railcar clod wash stainless steel abnormity corrugated floor, the cross section on floor are total by adjacent inversion, adjacent side
With nine identical isosceles trapezoids that top bottom connects are sequentially connected composition, i.e., two adjacent isosceles trapezoids are reversed with one another
It places, previous trapezoidal upper topside is upper, and the trapezoidal upper topside of the latter is under, the trapezoidal adjacent waist of adjacent two
Be it is shared, form the previous trapezoidal bottom top trapezoidal with the latter and be engaged togather, the apex angle 3 of isosceles trapezoid is circular arc
Shape is connected with front end pingbian 4 in the front end of nine connected isosceles trapezoids, is connected in the tail end of nine connected isosceles trapezoids
Tail end pingbian 5, front end pingbian 4, four inverted trapezoidal upper topsides 1 and tail end pingbian 5 are disposed on the same plane, and five
A trapezoidal upper topside just set is arranged on another same plane；The connection of front end pingbian 4 and head end isosceles trapezoid
For circular shape, the connection of end isosceles trapezoid and tail end pingbian 5 is circular shape.
The length of the upper topside 1 of isosceles trapezoid is 45 millimeters, and the length on the under shed side 2 of isosceles trapezoid is 38 millimeters, etc.
Trapezoidal a height of 13 millimeters of waist, the length of front end pingbian 4 and the length of tail end pingbian 5 are 30 millimeters, the apex angle 3 of isosceles trapezoid
Arc radius be 3 millimeters；The connection arc radius of front end pingbian 4 and head end isosceles trapezoid is 3 millimeters, end isosceles trapezoid with
The connection arc radius of tail end pingbian 5 is 3 millimeters.
The utility model passes through first by stainless steel roll bending slitting, then produces unit through dedicated numerical control wide cut roll-in cold-rolled forming section
Continuous rolling gradual change clod wash integral forming, finally, sawing essence scale is made.The utility model is in dedicated numerical control wide cut roller
Press the continuous rolling gradual change clod wash integral forming technical process of cold-rolled forming section production unit are as follows: first through in 6 sortie rolling formations
Position upper ripple, then through the 6 sorties adjacent lower wave of rolling formation symmetrical two simultaneously, then successively through same way shape other 3 pairs it is upper and lower,
Upper ripple.30 sorties are shared in this way and shape all waveforms, then after 4 sortie Full wave shape shapings setting, it is final to shape.
