Abstract

The invention discloses a manufacturing method of a trial-manufacture automobile front door outer plate. The method comprises the following steps of S1, drawing a plate material by a drawing mold to obtain a drawing element of the trial-manufacture automobile front door outer plate; S2, performing primary shaping cutting on the drawing element by using a five-shaft laser cutting machine; S3, usinga flanging mold to perform flanging on the drawing element after the shape cutting; S4, using a five-shaft laser cutting machine to perform secondary shape cutting on the flanged drawing element; completing hole cutting; forming the trial-manufacture automobile front door outer plate. The manufacturing method of the trial-manufacture automobile front door outer plate provided by the invention hasthe advantages that the mold design period is short; the volume weight of the mold is greatly reduced; the manufacturing cost is reduced; the assembly and debugging period cost is reduced; the development period of a soft mold element is shortened.

Description

technical field [0001] The invention relates to a manufacturing method of an automobile door panel, in particular to a manufacturing method of a trial-manufactured front door outer panel of an automobile. Background technique [0002] In the trial production of the car body, the covering parts have the characteristics of thin materials, complex shapes, mostly spatial curved surfaces with high connection requirements between curved surfaces, large structural size, high surface quality requirements, and good rigidity. At the same time, in the molding process of the automobile outer cover, the part cycle is relatively short, and the surface quality of the automobile outer cover is relatively high, and the cycle is very short, because any defect may cause delays in the assembly cycle of the vehicle. How to control the production cycle, reduce costs and improve production efficiency has always been an important subject of research in this field. Contents of the invention [00...
