Heat treatment tool and heat treatment process of vehicle

Abstract

The invention provides a heat treatment tool and a heat treatment process of a vehicle. The heat treatment tool comprises at least one structure unit, each structure unit comprises a shell and first reinforcing filler, a sealed containing cavity is formed in each shell in a limited manner, and the ends of the shells are used for being connected with welding parts; and the containing cavities are filled with the first reinforcing filler. The hollow shells are arranged and are filled with the first reinforcing filler, and therefore the structure units can have enough strength and rigidity at a high temperature, effective control over the size of a vehicle body is reinforced in the high-temperature heat treatment process, deformation of the vehicle body at the high temperature is restrained,and aftertreatment procedure measures are reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a heat treatment tool and a heat treatment process for vehicles. Background technique [0002] Taking armored vehicles as an example, armored vehicles generally use ultra-high-strength armor steel plates that have been quenched and tempered as the body material, and their tensile strength generally exceeds 1500MPa, which has good mechanical properties and protection capabilities. In the car body manufacturing process, the steel plates are tailor-welded into the car body through the welding process. Because of the inherent uneven heat input of the welding process, the mechanical properties of the welded joints are far lower than the inherent mechanical properties of the steel plates. At present, the weak weld area is strengthened by heat treatment after welding. Among them, the heat treatment tool is used to ensure that the heater and laying insulation materials are reasonably distributed ...

AI Technical Summary

Problems solved by technology

However, this heat treatment method cannot effectively control the size of the car body, and the car body is prone to deformation after being subjected to high temperature. Although the heat treatment can improve the performance of the welded joints to a certain extent, it cannot effectively reduce the mechanical properties of the steel plate welding heat-affected zone. The strength and protection ability still cause adverse effects. Therefore, after heat treatment, the protection of the weld seam of the car body needs to be additionally designed to strengthen the structure, which wastes the space of the whole car body and reduces the maneuverability and off-road performance of the armored car.
