METHOD FOR FORMING AN INTERNAL THREAD ON A BASE BODY

摘要

#CMT# #/CMT# The method involves inserting a threading tool (11) into an opening (32) in a base body (31), where the tool is provided with sections including a thread-forming structure. An entire internal thread is formed in the base body by rotation of the threading tool around a rotation angle of maximum 360 degrees. The rotation angle is relative to a value of a quotient of a full circle divided by a number of sections having the thread-forming structure. The sections are arranged in symmetry of rotation of an integral order before insertion of the tool. #CMT# : #/CMT# An independent claim is also included for a threading tool for forming an internal thread on a base body. #CMT#USE : #/CMT# Method for forming an internal thread on a base body using a thread former (claimed), to produce a threaded bush in a component. #CMT#ADVANTAGE : #/CMT# The entire internal thread is formed in the base body by rotation of the threading tool around the rotation angle of maximum 360 degrees, thus quickly and cost-effectively forming the internal thread on the base body. The method enables simple and economical production of the threaded bush. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a thread former. 11 : Threading tool 12 : Shaft 13 : Threading tool insertion end 31 : Base body 32 : Opening.
