Light hole vacuum carburizing gear for heavy duty gearbox
For some commercial vehicle companies supporting gearbox products, most of the self-made parts, especially gearbox gears, need to be vacuum heat treated and vacuum carburized and quenched. The processing process of some light hole gears is: blanking→forging→normalizing→rough turning→finish turni...
Heart Pacemaker Feeder Vacuum Brazing
A heart pacemaker is an electronic therapeutic device that is implanted in the patient’s body. A pacemaker ensures that the heart relaxes and contracts in accordance with the rhythm. The main function is to transport blood to the human brain and whole body through contraction and relaxatio...
Vacuum heat treatment process of Cr12 steel for tools and dies
Cr12 steel is a high carbon, high chromium cold work die steel. The carbon content of this steel is very high (mass fraction is 2%-2.3%), which is the highest carbon content in the cold work die steel currently used, and the chromium content is also very high (mass fraction is 11.5%-13.0%), which...
Vacuum heat treatment of different metal materials
Vacuum heat treatment technology is a very widely used technology, which is widely used in aerospace, electronics, and precision machinery. It has outstanding advantages in the production of metals that cannot be compared with ordinary heat treatment. Because the surface of the vacuum heat-treate...
Improvement of Gear Vacuum Carburizing and Quenching Process
The rotating shaft of the motorcycle starter is an important part of power transmission. Its toothed end is prone to wear and tooth chipping during operation. The rotating shaft is made of 20CrMo steel, the modulus of the end gear is 0.6, the number of teeth is 11, and the diameter of the pitch c...
Large -molding gear axis real vacuum carbonate quenching
1 Requirements for the requirements of the big mold Gear vacuum carbonic quenching In order to ensure abrasion resistance, the heat treatment is generally adopted by vacuum carburizing quenching process in order to ensure wear resistance. Its carburizing surface hardness generally requires 56 ~ 6...
Carbide-tipped Gear Hob Vacuum Brazing
Cemented carbide has small specific heat capacity and poor thermal conductivity. Especially when brazing large pieces of cemented carbide, the heating rate should be controlled, generally not exceeding 10°C/min, to ensure that the heat can be transferred in time and the thermal stress caused by u...
Vacuum Heat Treatment Process for Mining Gears
1 Selection of mining machinery gears Coal mine machinery bears a high dynamic load, and is often eroded by underground coal (powder) dust and harmful gases, and the working conditions are very harsh. With the increase of coal production, the power of coal mine machinery is increasing day by day,...
Effect of Additives on Vacuum Sintering of Ceramics
Vacuum sintering and densification of alumina ceramic materials requires a high temperature of 1600 ° C. It is precisely because of high temperature sintering that the process is difficult and the manufacturing cost is high, which has always been the main factor limiting its application. In order...
Fixture Selection in Vacuum Brazing Furnace
Vacuum brazing can obtain precise and bright joints, and the joints have excellent mechanical properties and corrosion resistance. Compared with other brazing methods, it has obvious advantages in the control of parts oxidation and parts deformation. Devices, water-cooled cold plates, and boxes a...
