Embodiment Construction

[0028] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0029] Such as figure 1 with 2 As shown, a window post of the present invention includes a post body 10 that is curved, has flanges 11 on both sides, and a stiffener 12 is longitudinally provided on the outer side of the post body 10.

[0030] The invention is provided with reinforcing ribs longitudinally on the outer side of the column body of the window column, which can avoid the phenomenon of stress concentration and distortion during the molding process of the window column, and the molding does not need to be adjusted, which improves the molding quality and production efficiency.

[0031] The outer end of the column body 10 is provided with a concave rib 13 which is a craft rib that is recessed toward the inne...

Abstract

The invention relates to the field of decorations in vehicles and discloses a window stand column and a forming method of the window stand column. The window stand column comprises a stand column body, the stand column body is bent, turnups are arranged on the two sides of the stand column body, and a reinforcing rib is longitudinally arranged on the outer side of the stand column body. Because the reinforcing rib is longitudinally arranged on the outer side of the stand column body, stress concentration and distortion can be avoided in the forming process of the window stand column, adjustment and repair are not need for the forming, and the forming quality and the production efficiency are improved. Further, concave ribs are arranged at the ends of the stand column body, excessive material at the ends can be absorbed, wrinkles are eliminated, and forming manufacturability, product quality and product rigidity are improved.

Description

Technical field [0001] The invention relates to the field of car interior accessories, in particular to a window column and a forming method thereof. Background technique [0002] The body of the rail vehicle is an integral welded structure composed of the underframe, side walls, end walls and roof. Among them, the side wall is the most important exposed part of rail vehicles. [0003] The side walls of the car body are welded to form a frame by window columns and side beams, and then spot welded on the outer wall panels. The window column is the main stress component, and its structure and strength directly determine the overall strength of the side wall. The surface quality and profile of the window column determine the overall external surface state of the side wall behind the wall panel. [0004] At present, in the production process of automobile window pillars, there will be a problem of distortion due to stress concentration after forming. The existing solution is to adjust...
