Abstract
A technology for making internal spiral thread of sleeve barrel by hot squeezing includes heating the sleeve barrel, inserting a core mould with spiral thread on its surface in the sleeve barrel, and squeezing the sleeve barrel. Its advantages are high productivity, and high utilization rate of raw material.
Description
The present invention is a kind of processing method of internal thread of sleeve, particularly a kind of method of manufacturing internal thread of sleeve by use of hot extrusion.
Internal thread of sleeve of the prior art its objective is two steel bar ends are screwed to together.Its structure is to be shaped on screw thread in the sleeve.Its processing generally must have machining through face work, boring, rough turn internal thread and several roads of finish turning internal thread.Its weak point is the waste raw material, expends energy height, and process velocity is slow, and production efficiency is low, and is of poor quality.
The objective of the invention is to solve above-mentioned weak point of the prior art, and a kind of method of manufacturing internal thread of sleeve by use of hot extrusion is provided.
Technical solution of the present invention is: with sleeve 2 heating.The core 3 that is shaped on screw thread on it inserts in the sleeve 2.Extrusion die 1,4 is promptly made screw thread to sleeve 2 application of forces on sleeve 2 inwalls.
The advantage that the present invention is had compared to existing technology is: save raw material, energy consumption is low, and process velocity is fast, production efficiency height, reliable in quality.Be suitable for producing in enormous quantities.
This accompanying drawing is that master of the present invention looks schematic diagram.
The present invention provides embodiment below in conjunction with accompanying drawing: with sleeve 2 heating.The core 3 that is shaped on screw thread on it inserts in the sleeve 2, and extrusion die 1,4 is promptly made screw thread to sleeve 3 application of forces on sleeve 2 inwalls then.After core 3 is withdrawed from reverse rotation, get final product according to required length cutting.Screw thread on the core 3 is that protruding, recessed screw thread all can.But heat supply extrusion process inner thread sleeve is used.
Claims (2)
1, a kind of method of manufacturing internal thread of sleeve by use of hot extrusion, comprise heating, cutting, it is characterized in that sleeve (2) is heated, the core (3) that is shaped on screw thread on it inserts in the sleeve (2), extrusion die (1,4) is to sleeve (3) application of force then, and reverse rotation is withdrawed from core (3) back and got final product according to required length cutting.
2,, it is characterized in that the screw thread on the core (3) is that protruding, recessed screw thread all can according to the method for manufacturing internal thread of sleeve by use of hot extrusion described in the claim 1.
