Title: Method and device for straightly drawing tube
Inventor: AKIYAMA MASAYOSHI
IPC: B21C1/00
Filed: 1986-03-11
Abstract: PURPOSE:To weaken a driving force giving rock motions and to perform the straight drawing by giving a tube stock circular rock motions around the axis of a die in the inlet side of the 1st die. CONSTITUTION:The 1st die 1 performs the main drawing >=80% of the draft allocation ratio and a die 2 positioned at the back of and on the axis of the die 1 is a straightening die. A rocking device 5 is installed in the inlet side of the die 1 and gives a tube stock A circular rock motions leaned at an angle alphato the die drawing center O-O and around the center O-O.
