Free forging is a simple and flexible basic forming method of metal plastic processing. It uses the upper and lower anvil blocks of forging equipment and some simple general tools to make the blank plastic deformation under pressure. Free forging can be divided into manual forging and machine forgin

Forging blank processing is the first process of forging production. The quality and productivity of forging blank will have an important impact on the quality, performance, life and economic benefits of the enterprise. The processing technology, equipment precision and performance of the forging bl

The free forging equipment commonly used by forging plants are: air hammer, air steam hammer and hydraulic press forging equipment. The nominal parameters of the air hammer are 65kg, 100kg, 150kg, 250kg, 400kg, 560kg and 750kg. The air hammer is simple in structure, easy to operate, easy to maintain

Heating before forging is an indispensable part of the whole forging process, which has a direct impact on improving forging productivity, ensuring forging quality, saving energy consumption and reducing product cost. The purpose and requirements of forging heating are as follows:1. Heating purposeI

During the production of forgings, in addition to ensuring the required shape and size of forgings, the performance requirements of forgings during use must also be met, which mainly include: strength index, plasticity index, impact toughness, fatigue strength, initial fracture degree, stress corros

The purpose of economic analysis of forging process is to explore the best technical scheme and pursue the maximum economic effect. In any production process, it is not only necessary to formulate the process, determine the process parameters and process equipment, but also to discuss the economic e

The process way to improve the plasticity of forgings and reduce deformation resistance In order to facilitate the flow forming of metal blanks, reasonable measures can be taken to reduce deformation resistance and save equipment energy during forging, the following methods are generally used to ach

The design of precision die forging is the same as that of ordinary die forging, and the precision forging drawing is prepared according to the product part drawing. It is the main basis for formulating precision forging process, designing precision forging die, manufacturing and acceptance of forgi

Forging is an article in which metal is pressed to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates a refined granular structure and improves the physical properties of the

The forging of large aluminum forgings not only needs to meet the required part shape and size, but also is important to break the as cast structure, refine the grain, uniform structure, forging shrinkage cavity, air hole, shrinkage porosity and other defects, so as to improve the internal quality o

The purpose of heat treatment for large forgings after forging is to refine the coarse grains caused in the forging process, eliminate work hardening and residual stress, reduce hardness, improve cutting performance, prevent white spots from forming inside the forgings, ensure the required metal str

The cooling modes of large forgings mainly include water cooling (including water spray cooling), oil cooling, air cooling (natural air cooling and air blast cooling), gap cooling (water air, water oil, oil air) and spray cooling. The commonly used quenching media for large forgings are water, oil a
