Embodiment 1

[0035] Such as figure 1 As shown, the trunk outer panel described in the embodiment of the present invention includes a license plate light installation profile, the license plate light installation profile is parallel to the X-axis of the vehicle body, and the trunk outer panel is parallel to The XY plane of the car body is made along the installation profile of the license plate lamp, and the part is divided into two parts. The upper part is above the intersection line, and the lower part is below the intersection line. The upper part includes the license plate lamp installation profile. The upper part and said lower part are joined together by laser brazing.

[0036] Specifically, see image 3 As shown, the lower part of the weld formed by the upper and lower parts is provided with a suction rib, and the mounting surface of the license plate lamp is provided with a suction rib. Among them, 1 represents the X-axis direction of the body of the part; 2 represents the stampin...

Embodiment 2

[0038] Embodiment 2 of the present invention provides a stamping process for parts on the outer panel of the trunk, wherein the rear license plate is arranged on the outer panel of the trunk, and the installation profile of the license plate light is parallel to the X-axis of the vehicle body. The trunk outer panel is divided into two parts by making an intersection line parallel to the XY plane of the vehicle body along the license plate light installation surface, and the trunk outer panel is divided into two parts, the upper part is above the intersection line, and the lower part is below the intersection line. The parts on the outer panel of the luggage case and the lower parts are respectively completed by a single stamping process, and connected together by laser brazing to form the outer panel of the luggage case. Among them, the laser brazing is a high-quality, high-precision, low-distortion, and high-efficiency welding method, but it requires high precision of stamping...

Abstract

The invention discloses a trunk outer plate and a punching process thereof, which belong to the field of automobile body-in-white part design and manufacture. The trunk outer plate disclosed by the embodiment of the invention comprises a license plate lamp installing sectional surface which is parallel to the X axis of an automobile body, a part is divided into two parts by the trunk outer plate through making a crossing line parallel to the XY plane of the automobile body along the license plate installing sectional surface, the upper part is positioned above the crossing line, the lower part is positioned under the crossing line, the upper part comprises the license plate lamp installing sectional surface, and the upper part and the lower part are connected through laser brazing. In theembodiment of the invention, the trunk outer place is divided into the upper part and the lower part, in addition, the laser brazing connection mode is adopted, and the problem of forming incapability caused by punching negative angle occurrence of the part when a license plate is arranged on a trunk cover is solved, through the structural design of the trunk outer plate, the quality of finished products is ensured, and simultaneously, the trunk outer plate is easy to process and manufacture.

Description

technical field [0001] The invention belongs to the field of automobile body-in-white parts design, and particularly relates to a trunk outer panel and its stamping process, that is, a sheet metal forming analysis and stamping manufacturing method for the trunk outer panel in the automobile body-in-white. Background technique [0002] With the continuous progress of the automobile industry, there are more and more changes in the appearance of automobiles, and the requirements for the surface quality of the car body are also getting higher and higher, which requires designers to continuously improve the design and process level. [0003] At present, through the investigation and analysis of market models, it is found that the installation profile of the license plate light is set on the outer panel of the trunk gradually becoming a trend. According to the requirements of relevant laws and regulations on automobile rear license plates, there are corresponding requirements for ...
