What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

The traction converter of the high-speed EMU adopts a fully enclosed circulating water cooling system

 

The heat dissipation capacity of the cooling system of the traction converter directly affects whether the converter can work safely and stably for a long time. For the cooling system of the traction converter of the CRH3 EMU, the dimensions and boundary conditions required for model simulation are obtained by actual measurement and dynamic test tests, ensuring the authenticity of the simulation analysis. Using ANSYS/FLOTRAN to simulate the flow field and temperature field of the heat exchanger of the traction converter cooling system in three dimensions. Compared with the previous empirical simplified formula method or experimental measurement method, it avoids the problems of poor calculation accuracy and difficult measurement. The distribution of wind speed, pressure and temperature of the heat exchanger of the cooling system can be easily and clearly obtained. By comparing and designing the temperature change of the coolant inlet and outlet pipes, the heat dissipation power of the converter cooling system is calculated, which provides a reliable basis for the performance evaluation and structural improvement of the CRH3 traction converter cooling system.

Traction converter cooling system structure The CRH3 high-speed EMU traction converter adopts a fully enclosed circulating water cooling system. The cooling system consists of an expansion tank, a water pump, a water-air heat exchanger, a cooling module, a pipeline, etc. The cooling medium is a mixture of high-purity water and antifreeze. Traction converter filter cutoff valve fan heat exchanger, quick connector expansion tank water pump pressure sensor temperature sensor, pressure sensor temperature sensor cutoff valve, traction converter cooling system working principle, the cooling medium is pumped to the main converter by the water pump In the heat exchanger outside the device, part of the cooling medium flows from the heat exchanger to the expansion tank, and the remaining part of the cooling medium flows back to the main converter after being cooled by the heat exchanger, flows into the 8 phase component modules connected in parallel, and communicates with the power device. Heat exchange; then it is pumped out by the water pump, and then pumped to the heat exchanger by the water pump, and so on.
