Processing method of titanium and titanium alloy wires

Abstract

The invention discloses a processing method of titanium and titanium alloy wires, which comprises the following steps: taking titanium and titanium alloy blanks, scalping by using a centerless turning mill to obtain bright titanium and titanium alloy wires without surface scales, trimming by using an angle grinder, annealing the titanium and titanium alloy wires in a vacuum furnace, taking out the titanium and titanium alloy wires, cold-rolling by using a roller die cold rolling mill, annealing the titanium and titanium alloy wires in the vacuum furnace, and rolling the titanium and titanium alloy wires by using the roller die cold rolling mill to obtain the titanium and titanium alloy wires with bright surfaces and without surface scales, wherein the diameters of the titanium and titanium alloy wires are Phi 1-3 mm. The processing method of titanium alloy wires in the invention realizes the production of titanium wires with high precision and high efficiency. The invention can be used for continuous production, thereby saving the prior acid and alkaline washing production technique, reducing a plurality of drawing steps, greatly enhancing the production efficiency and saving the production cost. The processing method can be used for producing high-precision titanium wire products which can not be produced in the prior art.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a processing method of titanium and titanium alloy wires. Background technique [0002] Titanium has excellent properties such as low density, high specific strength, corrosion resistance, small linear expansion coefficient, and good biocompatibility. High-precision titanium wire is used as a raw material for titanium equipment welding and titanium parts processing. It is generally used in two aspects. One is to further process and produce standard parts, precision instrument structural parts, pendants, wire mesh, etc. as structural parts; the other is to use it in large quantities. Welding in the manufacturing process of titanium equipment, aerospace vehicles, military products, stationery and sports products. The third is that the ultra-fine wire is directly used for the parts of the control equipment and used for the structural parts of the precision instrument. These th...

Problems solved by technology

In the case of high temperature heating, the diameter of the wire is controlled by the hole die. The straight wire is difficult to process, the surface accuracy is poor, the hydrogen and oxygen absorption is serious, and the weight of a single disc is low, which cannot meet the requirements for high-precision titanium wire; the surface of acid-base cleaning has great impact. Pollution, only the surface of titanium wire can be pickled, and bright wire cannot be produced

The straightening process will cause straightening lines that are difficult to eliminate on the surface of the wire, which will make the surface damage of the fine wire more serious.

The acid-alkali washing process is used for processing, and then the wire straightening machine is used to straighten the wire. This process is more complicated, the production efficiency is low, the yield rate is low, and a lot of energy is wasted, causing environmental pollution; at the same time, the surface of the original product is pickled surface , when the straightening machine straightens the wire, it will damage the surface, causing the surface to produce straightening lines that cannot be eliminated, and the surface is relatively rough
