Variable cross-section flexible roll forming equipment

The invention discloses variable cross-section flexible roll forming equipment which comprises a base, forming pass components are sequentially arranged at the top of the base, a feeding component and a discharging component are arranged on the two sides of the base respectively, each forming pass component comprises a base, two sliding platforms are arranged on the base, and assembling elements are rotationally installed on the sliding platforms. An upper roller and a lower roller are sequentially arranged on the inner side of the assembling element in the vertical direction, horizontal telescopic component sets are assembled on the two sides of the base, and the horizontal telescopic component sets can drive the assembling element to deflect and slide. The forming process is controlled by decomposing the motion trail of the rolling process of the variable-section product into mechanism motion parameters, the horizontal telescopic component set is mainly responsible for regulating and controlling the motion
