Disclosed is a sheet metal substrate for use in an elevator wherein the substrate is made of a sheet metal of small thickness by a special flanging process without impairing its structural integrity. The substrate is constructed from a single sheet metal and incorporates a top head and a bottom head to form an integral component. Such a configuration enables the head to be positioned in any manner, thus having rotational symmetry, which makes installation easier. This is achieved by a first 90 DEG bend (1a), followed by a second 90 DEG bend (1b), a third 90 DEG bend (1c) and a fourth 180 DEG fold (1d) of the open edge formed after the third 90 DEG bend (1c), by four special bends of the substrate on all the edges of the top and bottom sides.

    公开了一种用在电梯中的金属板材基板,其中,所述基板由小厚度的金属板材通过专门的折边工艺制成,而不损害其结构完整性。所述基板由单个金属板材构造而成,并合并顶部封头和底部封头以形成整体部件。这样构造使得封头可以以任何方式定位,因此具有旋转对称性,这使得安装更容易。这是通过在顶侧和底侧的所有边缘上对基板进行四次特殊弯曲来实现的——第一90°弯曲(1a)、随后是第二90°弯曲(1b)、第三90°弯曲(1c)以及第三90°弯曲(1c)后形成的开口边缘的第四180°折边(1d)。
