Double-layer sealing structure for armored car door and welding method

Abstract

The invention relates to a double-layer sealing structure for an armored car door. The structure comprises a car door body, a car body and a car door hinge. It is characterized in that the car door body is formed by a door board, a door lock reinforcing board and an annular reinforcement. an external sealing strip is fit with the outboard of the annular reinforcement and the external sealing strip is clung to the car body to form a first layer sealing structure; the car body is provided with a doorframe and a lock box reinforcing board, wherein an internal sealing strip is fit with the doorframe and the internal sealing strip is clung to the annular reinforcement to form a second layer sealing structure. The invention also relates to a welding method for the double-layer sealing structure for an armored car door. The method comprises following steps: making members; welding the car door body; welding the doorframe; assembling the car door body; assembling the sealing strip; adjusting and calibrating the car door; testing the sealing performance. By means of the structure and method of the invention, good sealing effect of armored car doors can be ensured to avoid water seepage. The problems of difficult formation of annular reinforcement, doorframes and door plates can be solved; the welding deformation of car door body is reduced; the welding and assembling accuracy and consistency of armored car doors are increased so that the quality of armored cars is guaranteed; the assembly efficiency is increased.

Description

technical field [0001] The invention relates to a double-layer sealing structure and a welding method for an armored car door. Background technique [0002] In recent years, the domestic armored vehicle industry has developed rapidly, and the demand for armored vehicles has also increased. As one of the core components of armored vehicles, the door of an armored vehicle, its sealing effect, production efficiency and quality will affect the production efficiency and quality of the entire armored vehicle product. Existing armored car door sealing structure, see figure 1 As shown, including the original door body 1, the original door hinge, the original body 2, and the original sealing strip 3, the original door body 1 is connected to the original body 2 through the original door hinge, and a 4mm second gap of 4 mm is formed between the original door body 1 and the original body 2. A gap a, the inner side of the original car body 2 is welded with a circle of the original reinf...
