[0002] The casting thermal deformation treatment device is a device used to heat treat metal castings to change their internal structure and performance. In the production process of metal castings, it is often necessary to heat treat the castings to eliminate residual stress, improve the mechanical properties of the material, increase hardness and strength, etc. Therefore, the casting thermal deformation treatment device is one of the very important equipment in the production of metal castings.

[0003] At present, there are often some problems in the casting thermal deformation treatment device, such as unreasonable support structure design and poor heating uniformity. The casting thermal deformation treatment device usually uses an external support structure to support the casting, while the embedded tooling is designed to embed the support structure into the casting to achieve more uniform support and fixation. This design can reduce the impact of external support on the casting surface and improve the uniformity and stability of heat treatment, but it does not solve the problem of uncomfortable air flow in the casting during heat treatment, and does not solve the problem of deformation of the casting during heat treatment due to different wall thicknesses.

This design can make the support plate more stable when moving vertically, thereby ensuring the stability of the device.

[0008] According to a casting thermal deformation processing device described in the utility model, the upper surface of the transverse support bar is fixedly connected with a push rod, and the upper surface of the push rod is in contact with the lower surface of the upper frame plate.
