Abstract

The invention provides a covered edge forming method and device. The covered edge forming method comprises the following steps that obtaining is carried out, a preset product parameter and a preset process parameter are obtained; determining is carried out, a product simulation forming parameter is determined according to the preset product parameter and the preset process parameter; and judging is carried out, the product simulation forming parameter is compared with the preset product parameter, if a comparison result does not meet the preset requirement, the preset process parameter is modified, the determining step and the judging step are repeated, until the product forming meets the quality requirement. According to the covered edge forming method, if the comparison result does not meet the quality requirement, the preset process parameter can be modified repeatedly until meets the quality requirement, that is, whether a product forming state meets the quality requirement or notis verified in advance, and mould repairing times are reduced, so that product design cost is reduced; and meanwhile, the covered edge forming method no longer depends on the technical requirement andexperience for molding analysis, so that the analysis result is more accurate.

Description

technical field [0001] The present invention relates to the technical field of wrapping molding, in particular to an wrapping molding method and device. Background technique [0002] The outer body cover needs to be hemmed. At present, the analysis of its hemming molding is generally carried out based on technical documents, which has caused the following disadvantages: [0003] 1. The shape of the outer cover is complicated, and the appearance features are obvious. The molding analysis of the outer cover only based on the technical documents cannot avoid the molding quality defects that appear in the later stage to the greatest extent, and cannot dig out the problems to the greatest extent. [0004] 2. Carry out molding analysis according to the technical requirements documents, and there is no verification method to verify whether the digital model of the outer cover product after the analysis meets the molding quality requirements, and can only wait until the PPV stage fo...
