TH31723A - Methods for producing metal parts with internal threads and machines for that - Google Patents

Abstract

DC60 (08/08/40) This invention relates to A method for producing internally threaded metal sections that can be separated from the core bar without turning. Part of metal with internal thread And the machines for that purpose. The process of inserting the second corebar vertically into the center of the first, divided into segments, and having a male thread on its periphery around the outer edge of it. Of the male thread of the first corbar, the pressure applied by the body Push a number of pods to the periphery around the periphery of the metal barrel in a concentricity to twist the metal barrel to transmit the moment with the first corbar male thread to the inner wall of the metal barrel to create an episode of Female thread: Separation of the second corebar inserted axially to the center of the first corebar from the male thread. And shrinking the diameter of the thread section Corebar male at one center to assist in separating the metal barrel. With an episode of the female spiral in there without twisting This invention involves A method for producing internally threaded metal sections that can be separated from the core bar without turning. Part of metal with internal thread And machines for that purpose. The process of inserting the second corebar in an axial direction into the center of the core. The first bar is divided into segments and has a male thread on its periphery, a metal barrel is placed on the end of the first corbar male thread, pressurized by a number of pushrods. Go to the periphery around the periphery of the metal barrel in a concentric twist to twist the metal barrel to pass the first corbar male thread to the inner wall of the metal barrel. To create episodes of Female Thread Separation of the second core bar into the axial axis. Go to the center of the core The first bar from the part of the male thread And the diameter contraction of the part of the male corbar thread at the center to aid in the separation of the metal With episodes of female threads In there without twisting

Claims (1)

1.Method for producing metal parts with internal thread Where it consists of episodes of inserting the first corebar axially into the center of the axially divided core into multiple segments, and there is an episode of the male thread on its outer periphery. Putting the metal barrel on the first corbar male thread, applying a certain amount of compression by the pushrod to the periphery around the periphery of the metal barrel in the center. To twist the metal barrel to send an episode of the core male thread One bar to the inner wall Of the metal barrel to form a part of the female thread.
