Abstract

PURPOSE:To efficiently form a sensitive drum, etc., without buffing or surface machining an extruding pipe by regulating a bearing length of an extruding die within a range of 5-10mm. CONSTITUTION:The die whose bearing length of the extruding die is regulated within the range of 5-10mm is used and an aluminium extrusion pipe 2 is extruded by an extruder 1 and cooled. A bent part 3a is formed on an end part of a pipe 3 having a specified length which is cut from the pipe 2 into the specified length and washed. This is immediately worked by ironing without buffing or surface machining and made as a worked pipe 4 by ironing, after cutting the bent part 3a, it is washed and formed into the sensitive drum, etc. By this method by regulating the bearing length to 5-10mm, the extruded aluminum pipe is made excellent in smoothness having no die mark, the sensitive drum material 5 is formed without buffing, etc.
