Embodiment Construction

[0030] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0031] see image 3 as well as Figure 4 , the embodiment of the present invention is a kind of automobile engine cover, namely the engine cover of automobile, and this engine cover 1 comprises the outer plate 11 of engine cover and the inner plate 12 of engine cover, and the edge of outer plate 11 and inner plate 12 adopts hemming process to carry out The hemming forms the hood assembly. Wherein, the two sides of the outer panel 11 are respectively bent downwards and inwards to form a rib 111 opposite (parallel) to the fender 2 on the side of the hood; the outer panel 11 and the rib 111 It is stamped and formed by a stamping die at one time.

[0032] The edge of the inner panel 12 is bent downward and wraps the edge of the outer panel ...

Abstract

The invention discloses an automobile engine hood, comprising an outer plate arranged on the outer surface and an inner plate arranged on the inner surface. The two side edges, opposite to automobile wheel fenders, of the outer plate are bent downwards inwards, and flanges opposite to the wheel fenders are formed on the side face of the engine hood; the edge of the inner plate is bent downwards and wraps the edge of the outer plate from the bottom to the top, to form a binding, folding glue is arranged on the binding in a pasting way, and the folding glue is arranged between the inner plate and the outer plate in a pasting way. The invention also discloses a processing method of the automobile engine hood. The automobile engine hood and the processing method can effectively improve the parting precision between the engine hood and the wheel fenders and improve the overall quality of the automobile engine hood.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile engine cover and a processing method. Background technique [0002] Existing car hoods are all double-layer sheet metal structures, including inner panels and outer panels. The edges of the inner panels and outer panels are fixed together by hemming process. Dry at high temperature to cure the hemming glue and bond the inner and outer panels to obtain an ideal rigid assembly. A top view of the hood figure 1 As shown, the schematic diagram of the wrapping structure of the inner and outer panels of the hood is shown in figure 2 shown. The existing engine cover and its machining process have the following problems: [0003] Before the hemming glue is cured in the hemming process, the friction force of the hemming of the inner and outer panels cannot prevent the relative movement between the inner and outer panels, which will cause a certain degree...
