Embodiment 1

[0036] Embodiment one: see figure 1 , figure 2 , image 3 with Figure 4 , the welding processing method for reducing the deformation of the armored car body is characterized in that it comprises the following steps:

[0037] The first step is to arrange process reinforcing ribs on the armored vehicle body: the armored vehicle body 30 is made of imported Swedish steel plate DOMEXProtect500 steel plate or steel plate code-named 685 (ie 30MnCrNiMo steel plate); The frame structure is formed by spot welding reinforcement ribs on the car body to reduce welding deformation;

[0038] The second step is to install the armored vehicle body; install the armored vehicle body 30 with the frame structure formed by spot welding reinforcement ribs on the welding robot workstation-positioner 31, and the armored vehicle body can rotate 360°; in order to adjust the seam to achieve The best welding position is convenient for welding the body of the armored vehicle;

[0039] The third st...

Embodiment 2

[0056] Embodiment two: see figure 1 , figure 2 , image 3 with Figure 4 , the body of the armored vehicle is made of imported Swedish steel plate DOMEXProtect500 steel plate, the overall heat treatment method is adopted to remove the welding stress of the armored vehicle body, and it is carried out in a trolley-type tempering resistance furnace (RT-800×350×200-7) and heated to 150-180°C, heat preservation for 20±2h, air cooling. All the other are the same as the first embodiment.

Embodiment 3

[0057] Embodiment three: see figure 1 , figure 2 , image 3 with Figure 4 , the armored vehicle body is made of 685 steel plate (30MnCrNiMo), the overall heat treatment method is adopted to remove the welding stress of the armored vehicle body, heated to 180-220°C in a trolley-type tempering resistance furnace, kept for 20±2h, and air-cooled. All the other are the same as the first embodiment.

Abstract

The invention relates to a welding method for reducing body deformation of an armored car. The welding method is characterized by comprising the following steps: (1) a process reinforcing rib is arranged on a body of the armored car; (2) the body of the armored car is mounted; (3) each gap is welded in a segmented symmetric skip welding manner in sequence; (4) the welding stress of the body of the armored car is removed; and (5) the process reinforcing rib is removed. The method can reduce the welding deformation of the body of the armored car, guarantees the body size of the armored car and the body size consistency, and improves the assembly efficiency and quality of armored car.

Description

Technical field [0001] The invention involves a welding processing method, especially a welding processing method that reduces the deformation of armored vehicles. Background technique [0002] In recent years, the domestic wheeled armored vehicle industry has developed rapidly, and the demand for armored vehicle products has become increasingly larger. As a key component of armored vehicles, the production efficiency and quality of armored vehicles will affect the production efficiency and quality of the entire armored vehicle.The car body material is alloy steel plates (such as imported Swedish steel plate Domexprotect500; codenamed 685 steel plates: 30mNCRNIMO), which is difficult to weld and welded.At the same time, due to the box structure of the armored vehicle, the size of the vehicle body is large, and it is basically welded by the armored steel plate material.Sexual guarantee is extremely difficult.If the consistency of the body size of the armored vehicle cannot be effe...
