Description

Tool for controlling thermal treatment deformation of vehicle arm of overhead working vehicle

Technical Field

The utility model relates to an automobile parts heat treatment technical field, concretely relates to a frock for controlling aerial work car arm thermal treatment warp.

Background

With the continuous deep advance of urbanization construction, the demand for various professional equipment such as emergency, maintenance and the like is increased, and higher requirements for the performance and quality of the equipment are provided. In particular to an overhead working truck which needs high-altitude operation in urban roads, fire fighting and emergency repair processes. With the current advance of light weight of automobiles, the arms of overhead working trucks also need to be continuously technically improved to meet the light weight requirements while ensuring the performance and quality of the arms. The ultrahigh-strength steel and the heat treatment process can greatly improve the strength of the material so as to reduce the thickness and the weight of the vehicle arm. However, since the vehicle arm can usually reach 3 to 4 meters in length, the vehicle arm shrinks due to severe cooling after being heated and enters a water pool quenching process. The wall thickness of the vehicle arm is very thin, and the thermal stress generated in the quenching process causes the bending deformation of the operation arm. If the bending deformation is too large, assembly obstacles are easy to appear, and even the performance is affected to cause product scrap. It is therefore a very important technique to reduce the heat treatment distortion of the long work vehicle arms.
