Features and advantages of the spinning process for ss pipe fittings
With the development of spinning technology, the spinning process gradually replaces the traditional process to produce ss 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 ss 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 weapons industry, and one of the most important advantages 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, and brittleness related to the weld.
And tension stress concentration and other disadvantages. Based on the above power and energy parameters, the body structure of the powerful spinning machine is designed. Focus on the comparison of the structure of the rotary wheel seat component of the spinning machine and determine the final plan; the design of the axial feed system and the radial feed system; the kinematics analysis of the transmission components of the spindle component structure; the new The designed unloading device is introduced in detail.
Finally, 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.
