Different Forging Deformation Methods When Forging Forgings
Mar 15,2024
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.

Does different forging ratio affect the quality of forgings?
The microstructure and mechanical properties of forgings are related to many factors, and the forging ratio is one of the main factors affecting the quality of forgings. Today we come to understand the forging ratio.

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.

What are the factors that affect the internal stress of heat treatment of shaft forgings?
There are three basic types of internal stresses that may be generated during heat treatment of shaft forgings. In actual production, shaft forgings always produce two or three basic internal stresses at the same time, so the residual stress of the actual workpiece after heat treatment is the result of the superposition of several basic internal stresses. The distribution of residual stress after superposition is very complex and closely related to the specific parameters of the heat treatment process. The following is a specific analysis of the main factors affecting the internal stress of the heat treatment of shaft forgings.

What are the uses of forgings?
Forging refers to a workpiece or blank obtained by forging and deforming a metal blank. By applying pressure to the metal blank to produce plastic deformation, its mechanical properties can be changed. Forgings according to the temperature of the billet in the processing, can be divided into cold forging warm forging and hot forging. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank.

How about the appearance inspection of shaft forgings?
The quality inspection of shaft forgings is divided into the inspection of appearance quality and the inspection of internal quality.

How does the forging factory ensure the quality of the forgings?
The inspection of forgings has the nature of random inspection. If the sample is qualified, it means that the entire accepted forging is qualified. Secondly, different types of forgings have different inspection items.

What are the contents of forging quality inspection?
The existence of forging defects, some will affect the quality of subsequent process processing or processing quality, and some seriously affect the performance and use of forgings, and even greatly reduce the service life of the finished parts, endangering safety. Therefore, in order to ensure or improve the quality of forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of defects in forgings, necessary quality inspection should be carried out to prevent forgings with defects that have a bad impact on subsequent processes (such as heat treatment, surface treatment, cold working) and performance from flowing into subsequent processes. After the quality inspection, according to the nature of the defect and the degree of impact on the use of the forging has been taken remedial measures to make it meet the technical standards or use requirements. Therefore, the quality inspection of forgings in a sense, on the one hand, is to check the quality of the forged pieces, on the other hand, it is to point out the direction of improvement for the forging process, so as to ensure that the quality of forgings meets the requirements of the technical standards of forgings and meets the requirements of design, processing and use.

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.
