Stainless steel pipe fittings are mainly used in aerospace and ordnance industries. One of the most important advantages of metal spinning process is that it can make integral seamless rotary hollow parts, which eliminates the defects of discontinuity, strength reduction, brittle cracking and tensile stress concentration related to welds.
With the development of spinning technology, spinning process has gradually replaced traditional process to produce stainless steel butt welded pipe fittings. The western developed countries of stainless steel fittings adopt technical blockade to our country on this technology. Therefore, our research goal is to achieve the ultimate reduction of stainless steel pipe spinning, stainless steel pipe diameter increased to 800mm. And the development of the corresponding specifications of the strong spinning equipment, the realization of large diameter stainless steel pipe production technology localization.
Stainless steel malleable iron pipe fittings are mainly used in aerospace and ordnance industries. One of the most important advantages of metal spinning process is that it can make integral seamless rotary hollow parts, which eliminates the defects of discontinuity, strength reduction, brittle cracking and tensile stress concentration related to welds. Based on the above force parameters, the structure of the powerful spinning machine is designed. The structure of the spinning wheel seat of the spinning machine is compared and the final scheme is determined. The axial feed system and the radial feed system are designed. The kinematics analysis of the transmission parts of the spindle structure is carried out. The newly designed unloading device is introduced in detail.
