Embodiment 1

[0059] The present invention has been applied to titanium alloy eccentric reducing tubes of Φ114.3 / Φ101.6 specifications. The weight of a single piece of blank has been reduced from 0.94KG to 0.8KG, and the material utilization rate has increased by 14.9%. The 50-60 minutes for each piece in the previous period was shortened to the current 5-6 minutes for each piece.

Embodiment 2

[0061] The present invention has been applied to titanium alloy eccentric reducing tubes of Φ101.6 / Φ88.9 specifications, the weight of a single piece of blank has been reduced from 0.62KG before to 0.49KG now, the material utilization rate has increased by 20.9%, and the forming time has decreased from before The 50-60 minutes for each piece in the previous period was shortened to the current 5-6 minutes for each piece.

Embodiment 3

[0063] The invention has been applied to titanium alloy eccentric reducing tubes of Φ88.9 / Φ73.0 specifications. The weight of a single piece of blank has been reduced from 0.5KG before to 0.39KG now, the material utilization rate has increased by 22%, and the forming time has been reduced from before. The 50-60 minutes for each piece in the previous period was shortened to the current 5-6 minutes for each piece.

Abstract

The invention discloses a forming process method for an eccentric aluminum alloy reducing tube. An eccentric reducing tube forming mould is extruded and formed on an oil press, so that the tube blanking length is shortened, the problems of a low raw material utilization rate, high labor intensity, low production efficiency, relatively high production cost, and the like are solved very well, the further improvement of relevant technical level of the shipbuilding industry and the ocean engineering industry in China is further facilitated, the manufactured reducing tube product meets various technical index requirements, the raw material utilization rate of the novel forming process is increased by more than 10% in comparison with that in a conventional extrusion method and the forming time for each eccentric reducing tube is shortened to current 5-6 minutes from the past 50-60 minutes, so that the method has the advantages that much forming time is saved, the production efficiency is greatly improved, the energy consumption is reduced and the like.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of metal material processing technology and manufacturing, and in particular relates to a forming technology method of a titanium alloy eccentric reducing pipe. [0003] 【Background technique】 [0004] It is known that titanium alloy is a material with excellent properties such as corrosion resistance and high specific strength. It is currently widely used in aviation, aerospace, ships, and chemical industries. Among them, titanium alloy reducing tubes are mostly used in ships, marine engineering, and chemical industries. In other fields, due to the characteristics of easy oxidation, high hardening tendency, high strength, low toughness, high yield strength and poor formability of titanium alloy, tube extrusion is generally used for forming. At present, titanium alloy reducer products adopt the production process of extruding concentric reducer→special tooling extrusion→scribing→cutting→grinding→eccentric redu...
