Spinning process of stainless steel pipe fittings

by:Mayer     2021-08-23
With the development of spinning technology, spinning technology has gradually replaced traditional processes to produce stainless steel pipe fittings. Western developed countries have imposed a technological blockade on my country regarding this technology. Therefore, our research goal is to achieve the ultimate thinning and spinning of stainless steel pipe fittings and increase the diameter of stainless steel pipe fittings to 800mm. And develop and produce powerful spinning equipment for pipe fittings of corresponding specifications to realize the domestic production of large-diameter stainless steel pipe fittings. Stainless steel pipe fittings are mainly used in the aerospace and weapon industries, and an important advantage of the metal spinning process is that it can make an overall seamless hollow part of the rotating body, which fundamentally eliminates the discontinuity, strength reduction, brittleness and cracks associated with the weld. Disadvantages such as tension stress concentration. Based on the above energy parameters, the body structure of the powerful spinning machine is designed. Focus on the comparison of the structure of the rotary wheel seat part of the spinning machine and determine the scheme; design the axial feed system and the radial feed system; analyze the kinematics of the transmission part of the spindle component structure; make a new design The unloading device is introduced in detail. The finite element software ABAQUS was used to analyze the strength and stiffness of the spinning machine's fuselage and movable beam, and improvement measures were proposed for the unreasonable design.
