The invention discloses a side wall plate of a railway vehicle, and a forming method and a forming die of the side wall plate. The side wall plate comprises: a first side wall, wherein the inner wallis provided with a first groove; second side walls which are provided with first kidney-shaped through grooves respectively and symmetrically connected to the two ends of the first side walls; a third side wall which is connected between the two second side walls and is opposite to the first side wall, wherein a first cavity is formed among the first side wall and the second side walls; a steppedframe, wherein one side of the stepped frame is connected to the bottom of the first side wall, a first notch is formed between the stepped frame and the second side wall and between the stepped frame and the third side wall, and a second cavity aligned with the first cavity is formed in the middle; and flanges which are connected to the lower surfaces of the top edges of the first side wall, thesecond side wall and the third side wall respectively. By means of the forming die, the side wall plate is formed, and the technical problems that the side wall plate is complex in shape, poor in forming quality, low in forming speed and not environmentally friendly in the forming process are solved.
本发明公开了一种轨道车辆的侧墙板、侧墙板的成型方法及成型模具,侧墙板,包括:第一侧壁,内壁上具有第一凹槽;第二侧壁,分别具有第一腰形通槽,对称连接在第一侧壁的两端;第三侧壁,连接在两个第二侧壁之间,与第一侧壁之间对面设置,并且与第一侧壁和第二侧壁之间形成第一空腔;阶梯框架,一侧连接在第一侧壁的底部,与第二侧壁和第三侧壁之间具有第一缺口,并且中间部位具有与第一空腔对齐的第二空腔;以及挡边,分别连接在第一侧壁,第二侧壁和第三侧壁的顶部边缘的下表面上;通过成型模具,使得侧墙板被成型,克服了侧墙板的形状较复杂,在成型时,成型质量相对较差,成型速度慢,而且不环保的技术问题。
