Evolution performance and bending degree of red copper tube

Three-roll planetary rolling is the main way of copper tube processing, so in the process of actual processing, this processing method has a wide range of application, has a higher practical application value. Based on this, this article will analyse the brass three-roll planetary rolling process, and study the brass three-roll planetary rolling process of rolling roller mechanical behavior, mainly including the brass three-roll planetary rolling process of rolling roller force, brass three-roll planetary rolling process of rolling roller unit structural mechanics model, the brass three-roll planetary rolling process of rolling roller finite element static, in order to study the copper pipe winding core head drawing The TP2 pipe with different drawing deformation was analyzed by OM and EBSD. The results show that after drawing deformation, the grain elongates along the drawing direction to form fiber structure, and the microhardness of the tube increases and the axial hardness is higher. The axial length and width of the grains are 80-100 μm and 8-10 μm, respectively. After the drawing deformation, the internal texture of the tube changes. With the increase of the deformation, the finite element dynamics of the roll in the three-roll planetary rolling process of copper tube are discussed. In daily life, serpentine pipes are widely used in refrigeration equipment, such as condenser and evaporator of air conditioners, condenser and evaporator of refrigerators, etc. The characteristic of these serpentine pipes is that each u-shaped pipe is of equal length. Given the length of each section of u-shaped pipe, in addition to using automatic bending machine, can also be manually using elbow to achieve.
