Description

TECHNICAL FIELD

[0001] The utility model relates to titanium alloy material preparation processing field especially, relates to a small deep hole bushing stamping die. BACKGROUND

[0002] The pipe blank of high-end titanium and titanium alloy seamless pipe is usually prepared by hot extrusion, and the hot extrusion ingot is usually subjected to the "bushing method" of drilling and then internally and externally bushing purple copper. The role of the bushing in the extrusion is to change the lubrication condition, prevent the metal from sticking to the tool, prevent the metal matrix from being polluted by air and improve the stress state in the initial stage of extrusion. Since the minimum eutectic temperature of titanium-copper metal is 850 DEG C, double bushings are used for titanium alloys such as TC4 with high extrusion temperature, the outer layer of the bushing is copper, and the copper and the metal matrix are connected by soft steel.

[0003] The double-bushing extrusion process has a small diameter of only Φ43mm for the drilled hole of the extrusion ingot and a long length of 750mm for the ingot, which belongs to a typical "small deep hole". Considering the lubrication and oxidation prevention effect of the bushing, in order to ensure close fitting, a copper tube with a size specification of Φ38*1.2mm is used to internally bush the copper inner bushing, and a soft steel tube with a thickness of 0.6mm is arranged between the copper tube and the inner hole of the ingot.

[0004] However, in the actual bushing operation process, since the purple copper is thin and soft, and the soft steel is thin, the tube type is prone to deformation, flattening and even bending when the purple copper tube and the soft steel tube are pressed in, the tube opening is easily torn by pressure, cannot be smoothly flanged, cannot meet the requirements of the bushing and the subsequent extrusion, and the deformed copper tube can only be treated as scrap metal, which greatly wastes the bushing material.

[0005] Therefore, it is necessary to provide a small deep hole bushing stamping die to solve the above technical problems. UTILITY MODEL CONTENTS
