Explore the materials commonly used for stamping parts

  Dalian stamping parts usually adopt high strength steel plate and ultra-fine grain steel with strength grade of 300-600 MPa. The requirements of material performance for automobile frame parts are frame, mid-plate of carriage and some parts used for support and connection. They are all important bearing parts. Most of them adopt die forming technology, which requires high strength and good plasticity of materials, as well as fatigue durability and collision energy. Absorption and solderability.

  External forces such as pipes and profiles are applied to produce plastic deformation or separation, thus obtaining the required shape and size of the workpiece (stamping) forming process. A large number of cold stamping processes have been used in the production of automobile stamping parts, which are generally used as materials for automobile stamping parts. Stamping and forging belong to plastic processing (or pressure processing), which is called forging.

  Stamping blanks are mainly hot-rolled and cold-rolled steel sheets and strips. The automobile body, chassis, fuel tank, radiator, boiler drum, container shell, motor, electrical appliances core silicon steel sheet and so on are stamped. Clean the surface of the outer covering with clean gauze. Inspectors should wear touch gloves and touch along the stamping part vertically close to the surface of the stamping part.

  This inspection method depends on the experience of the inspector. The choice of particle size depends on the surface condition (such as roughness, galvanizing, etc.). Fine-grained oilstone is recommended. The direction of polishing is basically along the longitudinal direction, and it fits well to the surface of stamping parts. Some special places can also be supplemented by horizontal polishing. Dalian Mold Processing uses clean gauze to clean the surface of the outer covering. Then use a clean brush to uniformly apply oil in the same direction to the entire outer surface of the stamping part.
