Abstract
The utility model discloses a cold-rolled stainless steel lower wallboard for a bullet train body, and solves the technical problem that a cold-rolled wide-area large-radian ultra-long plate cannot be provided in the conventional cold bending technology. The cold-rolled stainless steel lower wallboard comprises a cold-rolled stainless steel plate, wherein a bullet train body window section (1), an arc transition section (2) and a bullet train bottom connection section (3) are formed on the cold-rolled stainless steel plate in a cold bending way; the bullet train body window section (1) is connected with the arc transition section (2); the arc transition section (2) is connected with the bullet train bottom connection section (3); and the arc radius of the arc transition section (2) is 998 mm. According to the cold-rolled stainless steel lower wallboard, the welding workload of the bullet train body is reduced, and the appearance quality and the production efficiency of the bullet train body are improved.
Description
Technical field
The utility model relates to a kind of stainless steel materials, particularly the employed stainless steel materials spare by the cold bending process moulding of a kind of motor-car car body.
Background technology
The corrosion-resistant steel wallboard can be widely used in the Side fascia of stainless steel car bodies such as motor-car and subway, advantages such as it is wide to have breadth, and surface quality is good namely can be used for the application car body and also can be used for non-application car body, can reduce car body welding job amount, improve presentation quality and the production efficiency of car body.But existing clod wash technology has difficulties to the processing of the big radian overlength of wide format plate, particularly resembling motor-car car body wainscot sheathing namely requires high surface finish to require the clod wash sheet material of big radian again, behind the monoblock cold roll forming, cause resilience easily, can not reach strict surface finish and strict radian tolerance.
Summary of the invention
The utility model provides a kind of motor-car car body with clod wash corrosion-resistant steel wainscot sheathing, has solved the technical matters of the big radian overlength of the wide format plate that existing clod wash technology can't provide the monoblock cold roll forming.
The utility model overcomes the above problems by following scheme:
A kind of motor-car car body clod wash corrosion-resistant steel wainscot sheathing, the stainless steel sheet that comprises the monoblock cold roll forming, linkage section at the bottom of cold roll forming on the stainless steel sheet of monoblock cold roll forming has car body window section, arc transition section and car, car body window section and arc transition section are engaged togather, linkage section is engaged togather at the bottom of arc transition section and the car, and the arc radius of arc transition section is 998 millimeters.
The thickness of the stainless steel sheet of monoblock cold roll forming is 2 millimeters, and the length of car body window section is 661 millimeters, and the length of linkage section is 66 millimeters at the bottom of the car.
The utility model can be widely used in the Side fascia of stainless steel car bodies such as motor-car and subway, advantages such as it is wide to have breadth, and surface quality is good namely can be used for the application car body and also can be used for non-application car body, car body welding job amount be can reduce, the presentation quality of car body and the production efficiency of car body improved.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is assembled to the structural representation on the motor-car car body.
The specific embodiment
A kind of motor-car car body clod wash corrosion-resistant steel wainscot sheathing, the stainless steel sheet that comprises the monoblock cold roll forming, linkage section 3 at the bottom of cold roll forming on the stainless steel sheet of monoblock cold roll forming has car body window section 1, arc transition section 2 and car, car body window section 1 is engaged togather with arc transition section 2, arc transition section 2 is engaged togather with linkage section 3 at the bottom of the car, and the arc radius of arc transition section 2 is 998 millimeters.
The thickness of the stainless steel sheet of monoblock cold roll forming is 2 millimeters, and the length of car body window section 1 is 661 millimeters, and the length of linkage section 3 is 66 millimeters at the bottom of the car.
The car body window section 1 of the section of this wainscot sheathing is a straight line, and middle warping part is divided into a circular arc, and its bending spring is 998mm, and linkage section 3 is a linear portion at the bottom of the car.It is multiple that the surface can be 2B or 2G etc.The utility model adopts special-purpose wide cut corrosion-resistant steel clod wash manufacturing line, continuous roll bending Rolling Production, and the operation of rolling is taked the surface protection measure.
