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 reform presupposition of driving the vehicle’s secondary spring system at full speed

Comparison of the axial stiffness The bearing capacity of the combined spring P=P1+P2=(Gd18c3n1+Gd28c3n2) F=134.94F The bearing capacity of the original cylindrical spring P=Gd28c3n2=93.3F The axial stiffness of the combined spring The axial stiffness of the original spring= 134.94F93.3F=1.446, so the axial stiffness is obviously improved.

Comparison of lateral stiffness and bending stiffness The lateral stiffness of a single spring can be calculated by the following formula: Pr=Ed48nD32<1+43(HD2)2(2+L)>F The bending stiffness of a single spring can be calculated by the following formula: M=Ed416D2nH(2 +L) Fr is the combined spring axial stiffness. The original spring axial stiffness=d41D2n2H+d42D1n1Hd42D1n1H=1.225 This ratio shows that the improved combined spring has a greater increase in stiffness in all directions.

Improvement of the secondary spring The secondary spring is located between the bogie and the carriage. After the locomotive speeds up, the increase in the exciting force makes the secondary spring’s lateral stiffness low and its anti-resonance ability poor. For this reason, when it is ensured that the weight of the car body is not increased, the characteristics of the spring are changed by changing the shape of the spring. According to relevant data <1>, it is proved that the characteristic curve of a general cylindrical compression spring is approximately a straight line, the stiffness is stable, the structure is simple, and the manufacture is convenient. However, the spring is mainly along the axial direction, the transverse shear and bending rigidity is very poor, and the anti-resonance ability is poor. The reduced-diameter spiral conical compression spring has a gradually increasing characteristic curve, that is, the stiffness gradually increases, which is beneficial to eliminate or ease resonance, and has a compact structure and good stability.

concluding remarks

The design of the primary and secondary spring systems of high-speed electric locomotives plays a key role in the running quality of the entire locomotive. By improving their design, the exciting force generated during high-speed operation of locomotives can be greatly reduced, and the lateral stiffness and axial stiffness can be increased, thereby realizing active control of resonance of locomotives during high-speed operation and improving the safety of locomotive operation. Sex and stability.
