Bending method, winding method, bending equipment and winding system

The invention discloses a bending method. The bending method comprises the following steps: A, generating a tread winding section model according to engineering drawing parameters; b, layering the tread winding section model to form a plurality of layered tread winding section models; and C, bending the plurality of layered tread winding section models to form layered outlines. According to the bending method, a plurality of layered tread winding section models are bent, so that a plurality of formed layered contours are consistent with an actual tread outer contour, and an engineering drawing can more accurately describe the tread outer contour. The invention further discloses a winding method, bending equipment and a winding system. 本发明公开了一种折弯方法，包括：A.根据工程图参数生成胎面缠绕截面模型；B.对胎面缠绕截面模型进行分层处理，形成多个分层胎面缠绕截面模型；C.分别对多个分层胎面缠绕截面模型进行折弯处理，形成分层轮廓。折弯方法为通过对多个分层胎面缠绕截面模型进行折弯处理，使得其所形成的多个分层轮廓与实际胎面外轮廓一致，从而使得工程图能够更加准确描述胎面外轮廓。本发明还公开了一种缠绕方法、折弯设备和缠绕系统。
