目前,钢家具结构中的主要零件不少是用壁厚为0.8～1.5毫米的管材弯曲成型的。产品骨架采用弯管结构,可减少焊接和其它加工工序,具有生产效率高、节约辅料及坚固等优点。弯管零件所用管材较长,弯曲工艺本身对管材质量要求较高。钢家具生产中的弯管工艺是将管材在专用的机械设备上借助于型轮(管模)弯成一定角度和具有一 At present, many of the major components in the steel furniture structure are formed by bending pipes with a wall thickness of 0.8 to 1.5 mm. Skeleton product structure using the elbow, welding and other processes can be reduced, with high production efficiency, save materials and strong advantages. Elbow pipe parts used for a long, curved pipe itself on the quality of the higher requirements. Bending process in the production of steel furniture is to bend the pipe at a certain angle on the special mechanical equipment by means of a type wheel (pipe die) and to have a
