Vacuum gas Quenching of 45CrNiMo1VA Steel Spinning Mandrel
In order to improve the material utilization rate of cylindrical parts, factories often use strong spinning forming technology. Spinning mandrel (also known as mandrel) is an important process equipment that is located in the inner hole (or inner cavity) of the workpiece to guide and bear pressur...
Vacuum quenching of KMN steel structure
KMN steel is a low-alloy high-strength steel. Due to its excellent weldability and good comprehensive mechanical properties, it is often used to manufacture parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and petroc...
Vertical double-barreled shotgun receiver vacuum heat treatment
In the manufacturing stage of the vertical double-barreled shotgun, the quenching and oxidation deformation of the key component “casing” will be encountered. The riser casing is a high-precision gun with asymmetrical shape processed by CNC forming and milling, and it cannot be remedi...
Aluminum alloy chassis vacuum brazing process
1 Aluminum alloy chassis An aluminum alloy chassis is an important carrier of a certain equipment, and its quality directly affects the performance of the entire equipment. With product batches Put into production, although the traditional manual tungsten argon arc welding process can meet the pr...
Vacuum Brazing Technology of Aluminum Alloy Plate Radiator
The so-called vacuum brazing is to clamp the materials to be brazed together with fixtures, heat them in a vacuum furnace to melt the 4004, 4104 or 4N04 aluminum alloy solder into a high temperature liquid state, and fill the welded parts (3003 alloy) under the action of capillary force. ) to ach...
Compound Gas Nitriding Treatment Process For Swing Arm Bogies
The bogie is an important structure to ensure the safe operation of rail transit vehicles, and it is also the core structure for light rail or subway trains to run smoothly at high speed. The crank arm is a key part of the bogie structure. Its functions are as follows: First, when the vehicle sta...
Compressor impeller vacuum heat treatment
The impeller, also known as the working wheel, is the most important component on the compressor rotor. The impeller rotates at high speed with the main shaft, and does work on the gas. Under the action of the impeller blades, the gas rotates at a high speed with the impeller. Under the action of...
Carbide wood knife tools vacuum brazing
This paper takes the vacuum brazing process of cutting tool carbide as the research object. By studying its process and mastering its working principle, the blanks of rotary cutting tool carbide vacuum brazing can be qualified for batch production. Vacuum brazing of carbide tools is a very import...
