Causes and solutions of machining deformation of slender shaft forgings
The bending deformation of slender shaft forgings after fine cutting is analyzed by analyzing the influence of various related processes on bending deformation. The results show that the residual stress after straightening is the main cause of the bending deformation of the slender shaft. Through the stress relief annealing test and the adjustment of the production process, the residual stress is eliminated. Determine the adjusted production process as the solution.

In recent years, our company found in the processing of slender shaft forgings that the radial runout of the outer circle is normal when the forging blank is rough turning, but the radial runout is detected after the subsequent fine turning and grooving, the shaft parts are deformed, and the radial runout is seriously out of tolerance. This kind of unqualified phenomenon does not occur frequently, but once it occurs, about 1/3 of the shaft parts will become waste products due to unqualified finishing, which seriously affects the normal production of the workshop. In view of the above situation, this paper analyzes from various angles, finds out the reasons for the processing deformation of slender shaft parts, and puts forward practical improvement measures, so as to ensure the smooth progress of production.

Different Forging Deformation Methods When Forging Forgings
Different forging deformation methods, such as free forging, open die forging, closed die forging, extrusion, top upsetting, high-speed die forging, rolling, etc., its essence is to apply different forms of thermal and mechanical conditions to the blank through the corresponding forging equipment processing and die, so as to produce different physical fields and organizational properties evolution processes. The same forging, the choice of deformation mode is reasonable, the quality of the forging is very different, the wrong choice may make the forming process can not be achieved, not very reasonable choice will make forming difficult, prone to many quality defects.

What is the organizational stress of crane wheel forgings?
If there is phase change in the cooling process of crane wheel forgings, it will produce tissue stress. As with heating, the tissue stress is also caused by the change of the specific volume of the tissue before and after the phase change, and the outer layer and the heart phase change are different.
