Manufacturing process for automobile trunk cover

Abstract

The invention discloses a manufacturing process for an automobile trunk cover. The manufacturing process includes the following steps of outer plate machining, inner plate machining and overall combination of an automobile cover. At first, spot welding is carried out on a left annular part and a right annular part, and the left annular part and the right annular part are installed on an outer plate in a welded mode; secondly, a left thin L-shaped workpiece, a right thin L-shaped workpiece, a left thick L-shaped workpiece and a right thick L-shaped workpiece are correspondingly installed on an inner plate in a welded mode, an arched part is correspondingly installed in the middle of the inner plate, and then edge covering and ending are conducted on the inner plate and the outer plate; at last, seal gum is applied to the inner plate and the outer plate after the inner plate and the outer plate are pressed. According to the manufacturing process for the automobile trunk cover, after the outer plate and the inner plate are combined, edge covering and ending are conducted on the outer plate and the inner plate to enable the gap between the outer plate and the inner plate to be small, and air, water and the like are thoroughly isolated from the interior of the trunk cover through the seal gum to prevent oxidation.

Description

technical field [0001] The invention specifically relates to a manufacturing process of an automobile rear case cover, belonging to the field of auto parts. Background technique [0002] The trunk lid of a car is an important component of the car and belongs to the body system; the trunk lid is generally installed on the upper end of the trunk; the trunk lid and the trunk are hinged, and together with the trunk, it can be opened and closed; The items in the trunk are in contact with each other, which is easy to cause scratches and lead to oxidation. Therefore, the materials used in the trunk must have oxidation resistance and good formability; the existing car rear cover is generally produced together with the machine cover. The system structure is relatively large; the processing technology is relatively complicated, and the machine cover model can only be produced through multiple processes in the processing process, and the production efficiency is not high; at the same t...

[0002] The trunk lid of a car is an important component of the car and belongs to the body system; the trunk lid is generally installed on the upper end of the trunk; the trunk lid and the trunk are hinged, and together with the trunk, it can be opened and closed; The items in the trunk are in contact with each other, which is easy to cause scratches and lead to oxidation. Therefore, the materials used in the trunk must have oxidation resistance and good formability; the existing car rear cover is generally produced together with the machine cover. The system structure is relatively large; the processing technology is relatively complicated, and the machine cover model can only be produced through multiple processes in the processing process, and the production efficiency is not high; at the same time, due to the poor sealing of the inner and outer plates, it is easy to enter water and Oxidation of the air
