Eigenschaften und Anwendungen von Titan-Legierungen
Blog Details In 1948, the United States DuPont Company used the magnesium method to produce tons of titanium sponge – this marks the beginning of the industrial production of titanium sponge titanium, and titanium alloy is widely used in various fields because of its high specific strength, good corrosion resistance and high heat resistance. Titanium alloys have been used in aviation for more than half a century. In the 3C field, many mobile phones have been imported into the material, and more and more manufacturers are expected to use titanium alloy. So why is titanium alloy so popular? Properties of Titanium Alloys High strength: 1.3 times of aluminum alloy, 1.6 times magnesium alloy, and 3.5 times of stainless steel, the champion of metal materials. High thermal strength: the use temperature is several hundred degrees higher than aluminum alloy, and it can work for a long time at a temperature of 450 ~ 500 C. Good corrosion resistance: acid resistance, alkali resistance, atmospheric corrosion resistance, pitting corrosion, and stress corrosion resistance are particularly strong. Good low-temperature performance: Titanium alloy TA7 with deficient gap elements can maintain a certain plasticity at -253 ° C. High chemical activity: high chemical activity at high temperatures, easily reacts with gas impurities such as hydrogen and oxygen in the air to generate a hardened layer. The thermal conductivity is small, the elastic modulus is small: the thermal conductivity is about 1/4 of nickel, 1/5 of iron, 1/14 of aluminum, and the thermal conductivity of various titanium alloys is about 50% lower than the thermal conductivity of titanium. The elastic modulus of titanium alloy is about 1/2 that of steel. Classification and use of titanium alloys Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special functional alloys (titanium-iron hydrogen storage materials, titanium-nickel memory alloys). Although the history of titanium and its alloys is not long, it has won several honorable titles because of its extraordinary properties. The first won title is “space metal”, it is lightweight, has a specific strength, and high-temperature resistance, especially suitable for the manufacture of aircraft and various spacecraft. About three-quarters of the world’s production of titanium and titanium alloys are used in the aerospace industry. Many parts originally made of aluminum alloy have been converted to titanium alloy. 3. Analysis of machining characteristics of titanium alloy First of all, the thermal conductivity of titanium alloy is low, only 1/4 of steel, 1/13 of aluminum, and 1/25 of copper. Due to the slow heat dissipation of the cutting zone, which is not conducive to the heat balance, in the cutting process, the heat dissipation and cooling effect is very poor, easy to form high temperatures in the cutting zone, and the deformation and rebound of the parts after processing is large, increasing by cutting tool torque, fast cutting edge wear and reduced durability. Secondly, the thermal conductivity of titanium alloy is low, so the cutting heat accumulation in the small area near the cutting tool is not easy to distribute, the front tool surface friction is increased, it is not easy to remove chips, the cutting heat is not easy to distribute, and the tool wear is accelerated. Finally, the chemical activity of titanium alloy is high, and it is easy to react with the tool material at high temperatures, forming dissolution and diffusion, resulting in the phenomenon of sticking, burning, and breaking the knife. Machining center processing titanium alloy characteristics The machining center can process multiple parts simultaneously to improve production efficiency. Improve the machining accuracy of parts, product consistency is good. The machining center has the tool compensation function, which can obtain the machining accuracy of the machine tool itself. It has a wide range of adaptability and greater flexibility, such as the arc processing of the part, chamfering, and transition rounding, which can achieve multiple functions of one machine. Machining centers can be milling, drilling, boring, tapping, and a series of processing. Accurate costing can be performed to control the production schedule. Do not need special fixtures, save a lot of cost funds, and shorten the production cycle. Greatly reduce the labor intensity of workers. Multi-axis machining can be done with UG and other machining software. Prototek has been offering professional custom CNC machining parts for over 13 years.

Vorteile des Kaltextrusionsverfahrens
Blog Details Cold extrusion is to put the metal blank in the cold extrusion cavity, at room temperature, through the press fixed punch to apply pressure to the blank, so that the metal blank to produce plastic deformation and parts processing method. China has been able to cold extrusion of lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel, and stainless steel, and even bearing steel, high carbon and high aluminum alloy tool steel, high-speed steel, and other metals can be cold extrusion of a certain amount of deformation.In extrusion equipment, our country has the ability to design and manufacture extrusion presses. In addition to the general mechanical press, hydraulic press, cold extrusion press, friction press,, and high-speed high-energy equipment have been successfully used for hard extrusion production. Define Extrusion is a process that forces the gold chips to produce plastic flow through the gap between the punch and the die or the die outlet to make the hollow parts or the parts whose section is smaller than the blank section.If the blank is extruded without heat, it is called cold extrusion.Cold extrusion is one of the processing technology of no chip and less chip parts, so it is an advanced technology in the plastic processing of gold chips. If the blank is pressed by heating it to a temperature below the recrystallization temperature, it is called warm extrusion. Warm extrusion still has the advantage of fewer chips. Advantages Accurate sizing The general dimension accuracy of cold extruded parts developed in our country is up to 8 ~ 9 grades. If ideal lubrication is used, it is second only to the fine polishing surface. Therefore, parts manufactured by the cold extrusion method generally do not need to be reworked, and a small number only need to be finished (grinding). Save materials. Save materials The utilization rate of cold extruded materials can usually reach more than 80%. Such as the Jiefang brand automobile piston pin dynamic cutting material utilization rate of 43.3%, and with cold extrusion material utilization rate increased to 92%; For example, after the universal joint bearing sleeve is changed to cold extrusion, the material utilization rate is increased from 27.8% to 64%. It can be seen that the cold extrusion method can save a lot of steel and non-ferrous metal materials in the production of machine parts High production efficiency The efficiency of producing mechanical parts by cold extrusion is very high, especially in the production of large batch parts. The production by cold extrusion is several times, dozens of times, or even hundreds of times as compared with cutting. For example, cold-extruded piston pins for automobiles are 3.2 times more productive than machined ones, and cold-extruded piston pin automatons are now used to further increase productivity. The productivity of one cold extrusion automaton is equivalent to that of 100 regular lathes or 10 four-spindle automatic lathes. Wide application Such as special-shaped sections, internal teeth, special-shaped holes, and blind holes, These parts are difficult to complete by other processing methods, but it is very convenient to process with cold extrusion. High strength Because the cold extrusion adopts the cold deformation strengthening characteristic of metal materials, that is, the metal blank is in the state of three-way compressive stress during the extrusion process, and the material is compact and has continuous fiber flow direction after deformation, so the strength of the parts is greatly improved. In this way, low-strength materials can be used instead of high-strength materials. For example, in the past, 20Cr steel was used to manufacture liberation brand piston pins by cutting. Now, 20 steel is used to manufacture piston pins by cold extrusion. After the performance test, the cold extrusion method is higher than the cutting method to manufacture piston pins.
