Title: Cold forming tap
Inventor: HIKOSAKA KENSUKE
IPC: B23G5/06
Filed: 2001-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a cold forming tap in which tapping torque is low and durability is excellent by preventing increase of apparent area of a projecting portion due to interference of a grinding wheel. SOLUTION: Fig. 3 is a fragmentary enlarged front view of a male screw portion 3. A right side of Fig. 3 shows a leading part side of the male screw portion 3 and a left side of Fig. 3 shows a complete thread portion side of the male screw portion 3. A margin portion 5 is arranged so as to have a lead angle in the reversed direction with respect to the lead angle of the male screw portion 3. In other words, because the male screw portion 3 according to the present embodiment is a right hand thread, the margin portion 5 is a left hand thread. As a result, the margin portion 5 is arranged so as to be approximately perpendicular to the direction of the lead angle of the thread of the male screw portion 3.  Consequently, in a thread grinding process in which a grinding wheel is moved along the lead of the thread in order to grind the male screw portion 3, increase of the apparent width (area) of the margin portion 5 by the amount corresponding to the interference of the grinding wheel at the margin portion 5, as is in a conventional forming tap, does not occur. As a result, rotational resistance (tapping torque) in tapping can be reduced.
