Problems solved by technology

[0003] In order to overcome the problem that the existing anti-corrosion coating process cannot achieve ideal anti-corrosion coating effects on some special cavity structure parts of the car body, or although satisfactory anti-corrosion coating effects can be obtained, the investment is huge and the cost is high. The invention provides a simple and easy gluing anti-corrosion process for the automobile cavity structure without major changes to the original process and equipment, low process conditions, low cost, and also provides a gluing anti-corrosion process for this gluing anti-corrosion process In the process of gluing, it is a gluing masking tool that enables the non-glue-coating parts such as solder joints and assembly holes to be shielded conveniently and quickly

Embodiment 1

[0025] Such as figure 1 and figure 2 In the column cavity structure shown in the car body, the main reinforcement plate 2 and the auxiliary reinforcement plate 3 will form the main and auxiliary reinforcement plate cavity 1 after welding, and the maximum distance between the main reinforcement plate 2 and the auxiliary reinforcement plate 3 is less than 5mm, so it cannot meet the electrophoresis Penetration requirements. A gluing anticorrosion process for an automobile cavity structure is adopted, and a gluing covering tool is used in the process. The tool includes a cover plate and a handle. The cover plate is circular and its area is larger than any assembly hole on the center column. A circular cavity is dug out on one side of the cover plate, and the other side is connected with the bottom end of the handle. The handle is a bottleneck-shaped rotating body , the rotating body takes half of the "eight"-shaped arc as the bus line, and the central axis of the cover pl...

Embodiment 2

[0027] Such as figure 1 and figure 2 In the center column cavity structure shown in the car body, the side wall outer panel 6 and the main reinforcement plate 2 will form the center column outer cavity 5 after welding, and the side wall outer panel 6 and the main reinforcement plate 2 lack enough electrophoresis holes, which cannot meet the Electrophoretic penetration rate requirements, but in order to ensure the strength of the center column 4, it is not allowed to open too many holes on the side wall outer plate 6 and the main reinforcement plate 2 to meet the process conditions of electrophoretic film formation. For this reason, a glue coating anti-corrosion process for automobile cavity structure is adopted. First, before the welding process is implemented, expansion glue is evenly coated on the inner surface 7 of the side wall outer panel and the outer convex surface 8 of the main reinforcement plate. For expansion glue with a rate of 50%, the thickness of the glu...

Abstract

The invention discloses a gluing anti-corrosion process of a vehicle cavity structure, which comprises the steps of: firstly, coating expandable glue on a cavity member which is not welded, uniformly coating the expandable glue on a member surface of the inner surface of a cavity, and keeping away from positions of a welding spot and a mounting pore; and secondly, after the cavity member is welded, placing a formed cavity structure member in an environment with a temperature of 160-180 DEG C and baking for 30-35min to ensure that the expandable glue is expanded and cured. The invention also discloses a gluing shielding tool for the gluing anti-corrosion process, which is used for shielding the positions of the welding spot and the mounting pore during gluing. The gluing anti-corrosion process of the vehicle cavity structure does not need to largely change the traditional process and equipment, is low in process conditions and cost, and is simple and feasible. The gluing shielding tool for the gluing anti-corrosion process is help to ensure the gluing quality and the gluing working efficiency.

Description

technical field [0001] The invention relates to a gluing anticorrosion process and a tool, more specifically, it relates to a gluing anticorrosion process for an automobile cavity structure and a gluing covering tool for the process. Background technique [0002] Automobile body anticorrosion construction is an important part of automobile manufacturing. At present, electrophoresis, wax spraying and wax pouring and other glue coating anticorrosion processes are widely used in the automobile manufacturing industry. There are some cavity structures in the car body, such as the central pillars, upper side beams and other parts of the car. Since some car cavity structures cannot fully meet the construction requirements of the above processes, relatively speaking, the glue coating anti-corrosion process is carried out on these cavity structures. However, with the improvement of people's living standards and awareness, the attitude of car consumers towards the anti-corrosion of th...
