Deformation temperature and precision of precision die forging

Deformation temperature and precision of precision die forging

To prevent serious oxidation and decarburization on the surface of the blank during heating, it can be heated in a small, non-oxidizing open-flame furnace or a furnace that can effectively control the atmosphere. To prevent secondary oxidation during the cooling process of hot forgings, cooling can be carried out in a protected device. Forgings can also be placed in a grid sand box in order. When slow cooling is required, the company will cool the forgings in a hot sand box or asbestos powder.

Basis of Heat Treatment Process Design for Precision Forging Parts

Basis of Heat Treatment Process Design for Precision Forging Parts

The basis of the heat treatment process design of forgings is mainly the product part drawing and its technical requirements, the rough drawing and its technical requirements, the technical standards of the relevant process design, the technical requirements of the pre-and post-sequence of the heat treatment of forgings, as well as the technical level of the production site operator and the specific conditions of the equipment. In the following, the specific content and application of these bases are described in detail respectively.

Four Elements Affecting Precision Castings

Four Elements Affecting Precision Castings

Cast iron design process. When designing, in addition to determining the geometry and size of the casting according to the working conditions and metal materials, the rationality of the design should be considered according to the angle of the casting process characteristics and the casting alloy to avoid defects such as deformation, cracking and composition segregation.

Types and Application of Precision Forging Technology

Types and Application of Precision Forging Technology

Forging forming technology, also known as near-shape or near-net forming technology, refers to the forming technology of mechanical components that require only a small amount of processing or no longer processing. In production practice, people are used to forging forming technology is divided into: cold precision forging forming, hot precision forging forming, warm precision forging forming, compound forming, closed forging, isothermal forging, shunt forging and so on.

Time, cost, quality in the lean production process

Time, cost, quality in the lean production process

The tools and methods, management principles and implementation process included in lean production are a very large set of methodologies. Books such as (lean thinking) (machines that change the world) (Toyota model) describe this set of methodologies in more detail. This book does not expand these contents, but only dabbles in the basic concepts of lean production for some products.
