Description
Technical Field

Background
The opposite-wheel powerful spinning is developed on the basis of core die spinning, and the inner spinning wheel is adopted to replace a core die, so that the inner surface and the outer surface of a cylinder blank are simultaneously processed.
The spinning of the paired wheels adopts one or more pairs of internal and external spinning wheels to simultaneously process the internal and external sides of the workpiece. Compared with the traditional spinning method, the inner spinning wheel is used for spinning the paired wheels to replace a core mould, so that the flexibility of the process is effectively improved, the cost of a spinning mould is saved, the quality of the inner surface of a spinning part is improved, the defect of different deformation of the inner surface and the outer surface of the traditional spinning part is overcome, and the quality of a workpiece is obviously improved. The spinning of the paired wheels can adjust the position of the spinning wheel according to the size requirement of a workpiece, and flexible processing of cylindrical parts with different diameters and wall thicknesses is realized. The process is suitable for manufacturing large-size thin-wall cylinders in the fields of aerospace and military industry, and once the process is published, the process is concerned by major industry and countries in Europe and America. Because the application of the wheel spinning is only limited to the high-tech fields such as aerospace and the like and the research and development difficulty of the process and equipment is huge, only the United states and Germany carry out deep research and application on the wheel spinning respectively at present, and products are supplied to NASA (national aviation and aerospace agency) and ESA (European aerospace agency).
At present, no engineering application of large-size opposite-wheel powerful spinning equipment is reported in China, and only scientific research institutions such as colleges and research institutes perform relevant theoretical research and experimental simulation. A Zhaoyong ton professor team of the Western Ann university of traffic designs a pair of wheel spinning equipment of vertical bispin wheel, two external rotary wheels drive through a reverse lead screw and make its radial feed, and the axial is then through lead screw individual drive rotary wheel up-and-down motion. A small horizontal three-pair wheel spinning experimental structure is developed in a positioning chuck mode of an Archimedes spinning disk mechanism in yellow surge and the like of southern university, and an outward spinning wheel structure of the device is in a spiral groove positioning mode similar to a classic three-jaw chuck, is difficult to bear huge spinning pressure in powerful spinning of large-size workpieces, and is difficult to apply to processing of high-strength materials and large-size workpieces.
The current strong spinning equipment for the large-size paired wheel mainly has the following defects:
(1) the existing core mould spinning equipment has the problems of large core mould mass, high inertia, high mould cost, poor universality and long manufacturing period;
(2) at present, an external spinning wheel feeding device of the existing paired wheel spinning technology mostly adopts a cantilever structure, has poor rigidity, is difficult to bear huge spinning pressure in the powerful spinning of large-size workpieces, and is difficult to be applied to the processing of high-strength materials and large-size parts;
(3) the large-diameter thin-wall barrel is large in height, the torsional rigidity of the barrel wall is low, if the barrel is driven to rotate by a power source at the barrel bottom in a traditional mode, the barrel wall is prone to buckling deformation and huge torsional elastic deformation due to large torque and large spinning pressure of powerful spinning, the wall thickness reduction rate is limited during single powerful spinning, the production efficiency is reduced, and meanwhile the dimensional accuracy of the barrel wall cannot be guaranteed during the powerful spinning due to the torsional elastic deformation of the barrel wall.
