However, the special fixture is suitable for cutting a cross-shaped solid member, but is not suitable for a thin-wall sheet metal member, because the deformation of the steel is mainly caused by the internal stress and residual stress existing in the workpiece during the heat treatment process of the workpiece, and generally, when the surface temperature of the workpiece is increased to about 450 ℃, the steel is converted from an elastomer into a plastic body, the workpiece is plastically deformed, and the residual stress is also lost due to recrystallization when the temperature is about higher than the temperature. When the workpiece is heated rapidly, the temperature difference exists between the inner part and the outer part of the workpiece, the outer part reaches 450 ℃ to become a plastic region, the deformation is caused by the residual stress effect existing at the position with lower inner temperature, and after cooling, the region is the place where the deformation occurs. In the actual production process, even and slow heating is difficult to realize, and for a sheet metal component, residual stress existing at the outer edge part of the sheet metal component is larger, and the initial rise of the surface temperature of the workpiece tends to start from the outer edge of the workpiece, so that the deformation of the outer edge part of the workpiece is larger.
