Abstract

The invention provides a compensation method for preventing a door outer plate from upwarping. The method comprises the following steps: 1, extracting a to-be-processed surface from a computer model of a door outer plate, and segmenting the to-be-processed surface; 2, gradually shifting the to-be-processed surface towards the interior of a vehicle body by taking the segmentation edge of the to-be-processed surface as a reference; 3, reconstructing the to-be-processed surface to enable the to-be-processed surface to be smoothly connected with other surfaces, and completing the construction of a new model; 4, manufacturing a mold surface according to the new model. According to the invention, the lapping-in time of a bench worker on the door outer plate can be greatly reduced, the surface product quality is improved, and the debugging period is shortened.

Description

technical field [0001] The invention relates to the technical field of molding of vehicle door outer panels, in particular to a compensation method for preventing flange upturning of door outer panels. Background technique [0002] The exterior surface of the vehicle can be roughly divided into three categories: Class A, that is, the visible surface (door outer panel, side fender exposed part, hood outer panel, rear cover outer panel exposed part, etc.); , the appearance is not visible, but when the opening and closing parts assembly is opened, it can be seen intuitively or touched (door inner panel, rear cover inner panel, machine cover inner panel, side fenders and the opening and closing parts) Connected parts, etc.); C category, that is, a type of parts that are hidden inside the car body and cannot be seen (beams, reinforcements, floor functional parts, lap joints, etc.). Class A parts have the highest requirements for surface products, not only requiring qualified dim...
