Arc-shaped framework based on DCT coil configuration and manufacturing method thereof

The invention discloses an arc-shaped skeleton based on a DCT coil configuration and a manufacturing method thereof. The arc-shaped skeleton comprises a plurality of skeleton units which are spliced end to end; the axial surfaces of the plurality of framework units are positioned on the same plane, and the framework units with trapezoidal or fan-shaped axial surfaces are cut from the straight cylindrical DCT coil and are spliced to form the arc-shaped framework. The manufacturing difficulty is reduced, and the problems of large machining amount, high cost, long period and the like in the integral forming process are solved. 本发明公开了一种基于DCT线圈构型的弧形骨架及其制造方法，包括多个骨架单元，多个所述骨架单元首尾拼接；多个所述骨架单元的轴面处于同一平面，通过在直柱形的DCT线圈上截取轴面为梯形或扇形的骨架单元进行拼装形成弧形骨架。降低制造难度，解决了一体成型过程机加工量大、成本高和周期长等问题。
