Description

Technical Field

[0001] The invention relates to a manufacturing technology of metal fibers, in particular to a digitally controlled micron-level titanium metal fiber production device. Background Art

[0002] As we all know, titanium and its alloys have excellent properties such as light weight, high strength, corrosion resistance, and strong heat resistance. They are new structural materials with broad development prospects and are known as the "metal of the future." At present, titanium and its alloys are not only used in aviation and aerospace industries, but also widely used in chemical, petroleum, light industry, metallurgy, power generation and other industrial fields.

[0003] Strong corrosion resistance is one of the remarkable characteristics of titanium metal. This is because it has a particularly strong affinity for oxygen and can form a dense oxide film on its surface, which can protect titanium metal from medium corrosion. In most aqueous solutions, titanium metal can form a passivation oxide film on the surface, such as acidic, alkaline, neutral salt solution and oxidizing medium. It has good stability, better corrosion resistance than existing stainless steel and other non-ferrous metals, and even comparable to platinum. However, if it is in a medium that can continuously dissolve the oxide film on the surface of titanium, for example, titanium in hydrofluoric acid, concentrated or hot hydrochloric acid, sulfuric acid and phosphoric acid, titanium will be corroded in this medium because these solutions dissolve the oxide film on the surface of titanium. If oxidants or certain metal ions are added to these solutions, the oxide film on the surface of titanium will be protected, and the stability of titanium will increase. Titanium has very good stability in organic compounds, except for five organic acids (formic acid, acetic acid, oxalic acid, trichloroacetic acid and trifluoroacetic acid) at higher temperatures. Therefore, titanium is an excellent structural material in oil refining and petrochemical industry, and can be used to make various heat exchangers, reactors, high-pressure vessels and distillation towers. Titanium has better resistance to seawater corrosion than all other metals. Whether in static or high-speed flowing seawater, titanium has special stability. Therefore, titanium is an ideal material for seawater desalination equipment, and the application of titanium in this field will increase. However, although titanium has its unique effect, it is difficult to play a role in filtration and separation. The key reason is that metal titanium cannot be used for fiber bundle drawing, let alone preparation of micron-level fibers. Summary of the invention

[0004] To solve the above problems, the present invention discloses a CNC micron-level titanium metal fiber production equipment, which overcomes the shortcoming that metal titanium cannot be used for fiber bundle drawing. Ultrafine titanium and titanium alloy fibers are first prepared, and then the ultrafine titanium and titanium alloy fibers are used to prepare filter materials, new energy battery plates, fiber batteries, etc. with special high performance, so as to expand the application field of titanium metal.

[0005] A CNC micron-level titanium metal fiber production equipment comprises a computer main control cabinet, and a high-precision servo reducer, a five-axis robot three-dimensional precision cutting tool holder seat, a servo fiber former, a servo fiber cable arranger and a servo fiber take-up which are arranged in sequence; wherein the high-precision servo reducer and the five-axis robot three-dimensional precision cutting tool holder seat are both arranged on the main host seat; wherein the high-precision servo reducer is connected to a servo hydraulic chuck; the servo hydraulic chuck is used to clamp titanium alloy raw materials; the mechanical arm on the five-axis robot three-dimensional precision cutting tool holder seat is connected to a tool holder fixture, and a blade is installed on the tool holder fixture.

[0006] Furthermore, the tool holder fixture is made of chromium-molybdenum material.

[0007] Furthermore, the blade is made of special alloy material.

[0008] Furthermore, an angle is formed between the blade and the titanium alloy raw material.

[0009] Furthermore, the angle formed between the front bevel of the front end and the workpiece is the key to forming the fiber; the angle is 20-30 degrees. When the present invention is working, the titanium alloy material rotates at a certain speed, and the five-axis robot holds a special tool to cut the rotating titanium alloy material according to the set program. The cutting process includes horizontal feeding, and the robot selects the feeding torque according to the hardness of the material; while cutting, the robot holds the tool to move back and forth vertically and horizontally. The above cutting movement forms fibers, and the fibers are wound into finished products through the former, servo cable arranger, and servo cable take-up.

[0010] Beneficial effects of the present invention: It has the advantages of small cutting force, low cutting temperature, high workpiece surface quality, easy shoulder processing, high tool durability, stable processing and high production efficiency. Titanium or titanium alloy can be processed into ultrafine fibers with a fiber diameter of 10 microns. Fibers of this specification can be further processed into special high-performance filter materials - metal fiber sintered felt, etc. This filter material has high filtration accuracy and low filtration resistance.
