Abstract

The invention discloses a seamless thin-walled pipe drawing die for integrated circuits, comprising a drawing die set, an inner die set, a mandrel, a fixed-diameter inner die, a reduced-diameter inner die, an oil-coated die post, and an oil-coated ring groove , Oil storage tank, oil guide channel, reducing die groove, fixed diameter die groove, annular oiling mechanism, heat conduction channel and heat conduction copper pipe. The invention enables the mold to inject drawing oil into the pipe during the drawing process to form a protective oil film, reduce friction, improve the surface smoothness of the material, protect the mold, and prolong the service life. Rotating under the action effectively prevents Zhongtong from thinning and thickening the wall thickness beyond the control range, thereby improving the accuracy of the wall thickness and improving the production quality.

Description

【Technical field】 [0001] The invention relates to the technical field of seamless steel pipe processing equipment, in particular to the technical field of a seamless thin-walled pipe drawing die for integrated circuits. 【Background technique】 [0002] Seamless steel pipes have been widely used in the field of integrated circuits. With the development of the world economy and production technology, users have continuously improved the wall thickness accuracy of seamless steel pipes, and wall thickness accuracy has become an increasingly important quality of seamless steel pipes. Indicators and the main factors that determine its market competitiveness, which prompts enterprises to pay attention to wall thickness control technology and develop seamless steel pipes with high wall thickness accuracy to improve the performance and quality of seamless steel pipes. Moreover, drawing and polishing processes are mostly used in the market at present, which is difficult to meet the req...
