Problems solved by technology
Due to the need to improve product market competitiveness and enhance the visual impact of the vehicle, the decorative ridgelines of the body design are becoming more and more sharp. Therefore, the convex R of the forming convex mold ridgeline of the stamping die is continuously reduced or even approached to zero; but this The method is limited by the principle of stamping forming, and the edge sharpness of the body stamping parts obtained is limited

Embodiment Construction
[0022] refer to figure 1 , figure 2 , the body parts products are designed with equal material thickness, the radius of curvature of the product inner surface 2 = the product outer surface curvature radius R of the product outer surface 1 - material thickness S; in order to obtain a sharper ridgeline visual effect, the ideal appeal is after forming The obtained radius of curvature of the ridgeline outer surface of the body part is smaller than the given value in the product design drawing. figure 2 1 is the outer surface of the product, 2 is the inner surface of the product, S is the material thickness of the product; R is the radius of curvature of the outer surface of the product.
[0023] Usually, the shape of the forming punch in the stamping die is the same as the inner surface 2 of the product, and the forming die is the same as the outer surface 1 of the product. refer to image 3 , in the flat sheet forming process, the steel plate with equal material thickness un...

The invention relates to the field of vehicle body stamping dies, in particular to a reverse protruding formation method of a vehicle body ridge. The reverse protruding formation method of the vehiclebody ridge for a vehicle body stamping die is different from convex die 'vehicle body ridge part' sharpen-machining methods commonly applied in the industry, and utilizes a convex die 'vehicle body ridge part' to machine and form a cross section shape protruding out of a product and its extending line in a reserve R mode, so that the outer surface ridge of a stamped vehicle body part is sharper,and meanwhile the frequency of die maintenance performed for keeping the vehicle body part ridge sharp is remarkably reduced.
Description
technical field [0001] The invention relates to the field of stamping dies for car bodies, in particular to a method for forming reverse convex ridgelines of car bodies. Background technique [0002] The decorative ridgeline element plays an important role in the body shape of contemporary cars, and its artistic effect is often described as "dynamic, tough, sharp, masculine, muscular, sculptural, and layered" in media reports. Due to the need to improve product market competitiveness and enhance the visual impact of the vehicle, the decorative ridgelines of the body design are becoming more and more sharp. Therefore, the convex R of the forming convex mold ridgeline of the stamping die is continuously reduced or even approached to zero; but this The method is limited by the principle of stamping forming, and the ridgeline sharpness of the body stamping parts obtained is limited. Contents of the invention [0003] The invention provides a method for forming a reverse conve...
