钣金加工厂家对钢板下料采取哪些方法

通常在钣金加工下料的过程中,我们的操作面积是不受限制的,但是当操作面积很小,或者直接在不大的钢板上划线下料时,操作面积就受到了限制,这种情况下的笑料方法,一般叫钢板下料法。一般说来,适用于钢板下料法的构件,外形简单,结构单纯,尺寸较小,易于展开,像直圆管、矩形管、小弯头、正圆锥、正棱锥等等。
Usually in the process of sheet metal processing, our operating area is unrestricted, but when the operating area is very small, or directly on a small steel plate, the operating area is restricted. In this case, the method of the laughing material is usually called the steel plate method. Generally speaking, the component suitable for the steel plate cutting method is simple in shape, simple in structure, small in size and easy to expand, such as straight round tube, rectangular tube, small elbow, positive cone, positive pyramid and so on.

我们常用的方法有三角线展开法,将平面圆内侧圆周十二等分,对应连接后,将圆锥台侧面分成十二个小梯形。再连接小梯形对角线,于是形成二十四小三角形,然后再通过求实长等步骤,逐一展开各小三角形,完成展开图。
Our usual method is triangulation expansion, dividing the inner circle twelve of the plane circle, and then dividing the side surface of the cone into twelve small trapezoid according to the connection. Then connect the small trapezoidal diagonal line, then form twenty-four small triangles, and then expand the small triangles one by one through the steps of seeking truth length and so on, and complete the expansion map.

用钢板下料法划线时,由于操作面积的限制,一般都把放样图和展开图重迭地画在同一块钢板上,因此要特别注意线条的分辨,必要时涂以不同的颜色。

When using the steel plate down method to draw a line, the layout and the unfolding are often repeatedly painted on the same plate because of the limitation of the operating area. Therefore, special attention should be paid to the resolution of the lines, and different colors should be applied when necessary.
