There are defects in the cross section of the robot block die forging, which are characterized by turbulence and small cracks. This is due to the weakness formed in the weak deformation zone during the forging. Because the insufficient temperature is related to the unreasonable distribution of the two types of forging deformation, the heating temperature of the ingot must be controlled, and the deformation of the die forging must be correctly distributed twice. The ultra-high strength aluminum alloy die forging is the key component of the machine, It bears certain high stress during operation.

Nowadays, the process of forging large dies by robot block die forging is selected to obtain die forgings with acceptable dimensions and internal structural characteristics. Therefore, corresponding quality inspection must be carried out according to the technical requirements of die forgings. In fact, the quality inspection of die forgings not only indicates the factory's pre-inspection, but also more scientific management and the use of all quality inspection data, so as to continuously improve the production process and improve the level, The quality inspection of large matrix die forgings includes several parts, including appearance quality inspection and internal quality inspection. Each part includes a large number of inspection elements.
