Forging production process to forging plastic deformation as the core, composed of a series of processing processes.
(1) forging deformation before the main processes are cutting and heating process. The raw material is prepared according to the size required for forging, and the original blank is subjected to rust removal, if necessary, in addition to the surface defects, oxidation prevention and lubrication. The heating process is carried out according to the heating temperature and the production tempo required for forging deformation. Raw blank for heating.
(2) forging deformation process in a variety of forging equipment on the rough plastic deformation, the completion of forgings internal and external basic quality requirements. The process may include several processes.
(3) forging deformation after forging process, followed by the cooling process is forging. Then, in order to complement the lack of pre-process, so that forgings fully in line with the requirements of product drawings, but also need: trimming punching (forging die), heat treatment, calibration, surface cleaning and other processes. Sometimes, the forging cooling and heat treatment process closely in order to obtain a specific forging properties.
In the process, as well as forging factory, must carry out quality inspection. Inspection items include the collection of shape and size, surface quality, microstructure and mechanical properties, according to semi-finished products between processes and forging requirements.
Forging forming the essence of the tool or die by the role of external force imposed on the blank, the rough absorption of mechanical energy, the internal stress state of the distribution of changes in the occurrence of displacement and deformation of the flow of material for the forging, the blank is also due to be heated and absorbed heat , The corresponding internal temperature distribution changes. In the power and thermal energy driven, rough appearance of the shape and size of the internal organization and performance changes.
