Spinning forming device for head cover of seeker and forming method thereof

Abstract

The invention discloses a spinning forming device for a head cover of a seeker and a forming method thereof. The spinning forming device for the head cover of the seeker comprises a mold core clampedon a spinning machine; the profile of the mold core is coincident with the inner profile of the head cover of the seeker; a workblank to be machined is placed concentrically on the mold core, and theother side of the workblank is tightly ejected through a tail ejector; the outer periphery of the workblank is provided with an electromagnetic induction coil and a rotating wheel, and the electromagnetic induction coil is used for heating the workblank; and when the predetermined temperature is reached, the rotating wheel and the electromagnetic induction coil are separately fed from both sides in the direction of a busbar, and are formed under the pressing action of the rotating wheel. In the forming process, the head cover of the seeker is obtained by spinning forming aiming at different wall thicknesses of parts formed by a thin-walled curved busbar combined with a cylindrical shaped portion, the volume of the cylindrical shaped portion is calculated by the product of the wall thickness and the cross-sectional area, and a curved busbar portion is obtained by the law of positive rotation; and the rotating wheel and the electromagnetic induction coil are separately fed from both sides in the busbar direction of the mold core, so that the workblank is machined point by point into a thin-walled curved busbar rotating body. The number of spinning times of the spinning forming deviceis small, the implementation is simple, and the machining precision is high.

Description

technical field [0001] The invention belongs to the field of head cover processing of a seeker, and relates to a head cover spinning forming device of a seeker and a forming method thereof. Background technique [0002] Spinning technology is an advanced forming process widely used in military industry, aviation, aerospace and daily products. It has become one of the important forming methods for the production of small batches and multi-variety thin-walled rotary parts. Due to the use of local plastic deformation Instead of the overall deformation, the deformation resistance can be greatly reduced and equipment investment can be reduced. Moreover, the plastic processing technology has the characteristics of high flexibility, low tooling cost, and short production preparation period, and has obvious economic benefits in small and medium batch production. [0003] Spinning forming is a special pressure processing method. It belongs to the elastic-plastic deformation method. ...
