角铁是用铸铁制成的车床附件，通常有两个互相垂直的工作表面。在角铁上有长短不同的通孔，用以连接螺钉的通过。 由于工件形状、大小不同，角铁除有内、外角铁之分外，还可做成不同形状，以适应不同的加工要求。 应具有一定的刚性和强度，以减少装夹变形。为此，除了在结构上增加一些肋、肋板外，还应在铸造后进行时效处理。 角铁的工作表面和定位基准必须经过磨削或精刮研以确保接触性能好、角度准确。角铁可以用作搭接结构间的连接件， 一般用于建筑工程结果上。根据应用位置不同，角铁的受力结构也就不同。角铁属于碳素结构钢，采用低碳方钢胚、 废品钢等制作，有着很好的塑形、可焊性等特点。它被分为不等边等厚，不等变不等厚这两种类型， 一般国内的规格范围控制在3~9m、4~19m等。 Corned iron is a lathe attachment made of cast iron, usually having two working surfaces perpendicular to each other. There are through holes of different lengths on the corner iron to connect the passage of the screw. Due to the different shape and size of the workpiece, the corner iron can also be made into different shapes, in order to meet the different processing requirements.Have certain rigidity and strength to reduce clamp deformation.To this end, in addition to adding some ribs and ribs to the structure, it should be treated after casting. The working surface and positioning reference of angle iron must be ground or scraped to ensure good contact performance and accurate angle. Corned iron can be used as a connection between bridging structures and is generally used in the results of construction engineering. Depending on the location of the application, the stress structure of the angular iron is also different. Angle iron belongs to the carbon structural steel, using low-carbon square steel embryo, scrap steel production, has a very good shape, weldability and other characteristics.It is divided into two types of unequal edge thickness and unequal thickness, and the general domestic specification range is controlled at 3~9m, 4~19m, etc.
