采用折合或弯曲接头连接零件,是获得永久性或半永久性及中等强度连接的一种最容易和最经济的方法。在不用螺钉、铆钉或其它零件连接时,零件制造简单,装配方便。用接头紧固的缺点,主要是带接头的构件最大厚度仅限于0.3～2毫米(原文为0.012～0.08英寸)时,此种方法不适于高强度连接,并且接头构件在弯曲后,不允许有弹性回跳,还要有足够的韧性。采用这种连接的材料为软钢、铝、青铜和黄铜。
The use of folded or bent joints to connect parts is the easiest and most economical way to get permanent or semi-permanent and medium-strength connections. Parts are easy to manufacture and easy to assemble without screws, rivets or other parts. The shortcomings of fastening with joints, mainly with the maximum thickness of the joint member is limited to 0.3 to 2 mm (the original text of 0.012 to 0.08 inches), this method is not suitable for high-strength connections, and the joint member is not allowed after bending Flexible bounce, but also have enough toughness. The material used for this connection is mild steel, aluminum, bronze and brass.
