Casting production process

Casting production process

Forging deformation process before the main material and heating process. The blanking process prepares the original blank according to the specifications and sizes required for forging, and if necessary, the original blank shall be treated with rust removal, surface defects removal, oxidation prevention and lubrication, etc. The heating process heats the original blank according to the heating temperature and production beat required by forging deformation.

Common forging form: free forging

Common forging form: free forging

Forging refers to the processing method in which the metal is deformed by impact force or pressure between the upper and lower anvils or forging dies. It can be divided into two types: free forging and model forging.

What is the difference between forging, stamping and casting? Look at it and you will understand.

Casting: It is the transformation of a shapeless molten metal into a shaped solid. Forging: The transformation of a solid of one shape into a solid of another shape.

Classification, characteristics and equipment used in forging

Classification, characteristics and equipment used in forging

Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components.

The role of forging process and the scope of application of forgings

The role of forging process and the scope of application of forgings

Forging process plays an important role in the production of forgings. The process is different, the quality of the forgings (shape, dimensional accuracy, mechanical properties, flow lines, etc.) are very different, the type of equipment used, tonnage is also very different. Some special performance requirements can only be solved by replacing materials with higher strength or new forging processes, such as aero-engine compressor discs and turbine discs. During use, the temperature gradient of the disc rim and the disc hub is large (up to 300-400 ℃). In order to adapt to this working environment, dual-performance discs have appeared. Appropriate arrangements of forging processes and heat treatment processes are adopted, the dual performance disc produced can indeed meet the high temperature and room temperature performance requirements at the same time. Proper arrangement of the process not only affects the quality, but also affects the production cost of forgings; the most reasonable process should be the best quality, lowest cost, convenient and simple operation, and can give full play to the potential of the material.

Common defects in forging forming process

Common defects in forging forming process

Free forging is a simple and flexible metal forming method. Although free forging is recognized as an outdated and uneconomical forging forming method for small and medium-sized forgings in batch or mass production, it is still a suitable and economical production method for small batch or unit production, especially for large forgings, free forging on hammer or hydraulic press. Free forging is to control the shape and size of forgings by the operation of workers, so the precision of forgings is poor, the forging productivity is low, and the labor intensity is high.
