The importance of forging process plan

Forging process analysis of specific forgings, comprehensive use of metal pressure processing principle, forging technology, metal science and heat treatment, forging equipment and automation and other disciplines knowledge and factory production practice. From the analysis of the function and technical requirements of parts, explore various possible deformation modes, design reasonable forgings structure, determine the appropriate machining allowance, tolerance and process dressing, drawing forgings. According to the forgings shape size and deformation mode, calculate the deformation required force, select the main forging equipment. According to the forging material and deformation mode to determine the heating temperature, choose the heating mode and heating equipment.

Before the alternative process plan is obtained, the forging process which is not reliable in technology should be screened and eliminated. The so-called unreliable forging process includes the following aspects: unable to complete the forging forming; Dimensional accuracy can not meet the requirements of drawings; Metal streamline is unreasonable or cannot meet the requirements of metal streamline of parts; Can not meet the strength, stiffness and hardness of parts and other performance requirements; Unable to meet the requirements of quality tolerance and dimensional tolerance for the use of parts or subsequent processing; Can not obtain the required forging equipment or die, can not get the necessary power, fuel, raw materials, auxiliary materials supply.

Forging process analysis is a system engineering problem. Although it is still an analogy and inference based on experience, it is a method characterized by the mental work of craftsmen. Therefore, it is required that those engaged in this work should be familiar with the existing production methods and master the characteristics, application scope and restrictions of various forging process schemes.

To sum up, the forging processing methods of specific forgings have a comprehensive understanding. If the analysis is based on the existing knowledge and experience, the proposed several process plans will be limited to the existing production mode, and on this basis, further thinking and new ideas will be put forward. In view of the existing inherent shortcomings of each scheme, in the case of deformation mode, reduce process, save energy, save material possible, improve or change the forging, conceive a new process scheme. The new idea should go through the above procedures to calculate various technical data and form a complete process scheme.
