A Forming Process for Uniform Spinning of Titanium Alloy Sheet by Cluster Steel Ball Half-mold

Abstract

The invention relates to a forming process for uniformly spinning titanium and titanium alloy plates by a cluster steel ball half die. The forming process comprises the following steps that titanium and titanium alloy plate blanks are spun on a spinning machine; the titanium and titanium alloy plate blanks are installed on the spinning machine by spinning the cluster steel balls and a hydraulically jacked die; and the hydraulically jacked die is used for being in contact with the titanium alloy plate blanks and a motor drives a stirring wheel to stir the cluster steel balls to spin the titanium and titanium alloy plate blanks. The forming process solves the problems of low forming precision and poor quality of the titanium alloy plate blanks caused by single-point spinning roller spinning,improves the mechanical properties of titanium and titanium alloy, realizes the cold forming process of the titanium alloy, and obtains the titanium and titanium alloy finished products with high adhesion degree and forming precision.

Description

technical field [0001] The invention relates to the technical field of metal material cold forming processing technology, in particular to a uniform spinning titanium alloy plate forming technology of clustered steel ball half-molds. Background technique [0002] Titanium and titanium alloys are structural metal materials with low density. They have the characteristics of high strength and high specific strength, so they can reduce weight to a large extent. In addition, they have good fracture toughness, high fatigue strength, strong crack growth resistance, and can Good toughness, excellent corrosion resistance, good heat resistance, better performance at low temperature, low thermal conductivity and non-magnetic and many other advantages. It is an ideal industrial metal material. Titanium and titanium alloys were first used in aircraft and engines in the aviation industry. Later, with the development of technology, the development and improvement of various forming and p...
