管端成形的主要对象是管接头。以管子作原材料成形机械零件,可节省切削、焊接等工序,减少材料费,大量降低成本,并能使产品轻量化。因此近年来,管子成形被作为高附加价值化技术而受到重视。 The main object of pipe end forming is the pipe joint. Tube-forming raw materials for mechanical parts, cutting, welding and other processes can be saved, reducing material costs, reduce costs and reduce the product weight. In recent years, therefore, pipe forming has been valued as a high value added technology.
