Abstract
The utility model discloses a hollow thin-walled profile plate, the design goal of which is to realize light weight design and the automatization for assembling and welding an aluminum alloy bodywork under the premise of achieving the parameter requirements for the rigidity and intensity. An integrated structure is formed through the extrution technique; a plurality of continuous inclined rib plates are arranged between an inner plate and an outer plate; the inside space of the profile plate is divided into a plurality of isoceles triangles by the neighboring inclined rib plates; the two ends of the profile plate are provided with plugging sheets used for connecting in a plugging way. The profile plate at the connection location between the inclined rib plates and the inner plate or between the inclined rib plates and the outer plate are thicker than the profile plate on the other part of the inner plate or the outer plate. The plugging sheets of the two neighboring profile plates are mutually connected in a plugging way and form a welding divided edge with an angle of 60 to 80 degrees.
Description
Technical Field
The utility model relates to a constitute aluminum alloy cavity thin wall section bar board of rail vehicle automobile body belongs to the machine-building field.
Background
At present, the speed per hour of domestic railway vehicles reaches more than 200 kilometers, and the wide use of motor train units with the speed grade of more than 200 kilometers puts higher requirements on the design of rigidity and light weight of train bodies.
The existing vehicle body section is generally made of carbon steel, stainless steel and aluminum alloy. The aluminum alloy vehicle body structure comprises a framework shell, a thin section single shell, a hollow section double shell structure and the like.
The vehicle body section structure cannot achieve unification of rigidity, strength and lightweight performance parameters, so that certain difficulties exist in design and use of a high-speed vehicle body.
SUMMERY OF THE UTILITY MODEL
Cavity thin wall section bar board, its design aim at solve above-mentioned problem and adopt aluminum alloy cavity thin wall extrusion section bar board, under the prerequisite that reaches rigidity and intensity parameter requirement, realize the automation of lightweight design and aluminum alloy automobile body assembly welding.
In order to achieve the design purpose, the hollow thin-wall section bar plate is formed into an integrated structure through an extrusion process.
The main structural scheme is that a plurality of continuous inclined rib plates are arranged between an inner plate and an outer plate, and the inner space of a section plate is divided into a plurality of isosceles triangles by the adjacent inclined rib plates.
And inserting pieces for inserting are arranged at two ends of the section plate.
In order to improve and further improve the rigidity and strength indexes of the section plates, the section at the joint of the inclined rib plate and the inner plate or the outer plate is thicker than the section at other parts of the inner plate or the outer plate.
In order to improve the spot welding connection performance of the profile plates after being spliced, the inserting pieces of two adjacent profile plates form a welding groove of 60-80 degrees after being spliced with each other.
According to the above scheme, the utility model discloses cavity thin wall section bar board, overall structure rigidity and intensity are higher, adopt grafting interconnect moreover, had both helped automobile body lightweight design, can realize the automation of aluminum alloy automobile body assembly welding again.

Detailed Description
Example 1, as shown in fig. 1 and 2, the hollow thin-walled profile plate is formed into an integral structure through an extrusion process. Wherein,
a plurality of continuous inclined rib plates 3 are arranged between the inner plate 1 and the outer plate 2, and the inner space of the section plate is divided into a plurality of isosceles triangles by the adjacent inclined rib plates 3.
The two ends of the section bar plate are provided with inserting pieces 4 for inserting, and welding grooves 6 of 70 degrees are formed after the inserting pieces are inserted into each other.
The section bar at the connecting part 5 of the inclined rib plate 3 and the inner plate 1 or the outer plate 2 is thicker than the section bar at other parts of the inner plate 1 or the outer plate 2.
In the embodiment, the thickness of the hollow thin-wall section is 50mm, and the width is 300-500 mm.
The thickness of the inclined rib plate 3 in the section bar is 1.5mm, and the span of an isosceles triangle divided by the inclined rib plate 3 is 80-120 mm.
The two adjacent section plates are connected in an inserting mode, and the inserting distance is 7 mm.
