Automotive sheet metal parts have high production efficiency in industrial production

Metal plastic forming is the process of using the plastic properties of metal materials to make them have the desired shape. After the metal material is formed, its structure and properties are improved and enhanced. All components subjected to alternating loads or under severe stress conditions generally have to go through the plastic forming process to meet the requirements for use. Plastic forming is a chip-free forming method, which enables the workpiece to obtain a good streamline shape and reasonable material utilization. The plastic forming method can make the workpiece size reach higher precision, and the automobile sheet metal parts have high production efficiency.

Plastic forming is divided into cold forming, warm forming and hot forming. Warm forming should consider the effect of temperature on material properties, and hot forming should also consider the creep effect of the material. Metal plastic forming includes block forming, sheet forming and rolling (see plastic mechanics). All kinds of plastic forming are premised on the plastic properties of metal materials, all need external force, all have the influence of external friction, and all follow the common laws of metallography and plastic mechanics.

The method of applying the principles of plastic mechanics to study the laws of metal forming is called plastic analysis of metal forming, and its tasks are:

  • ①Study various solutions related to mechanics in the plastic forming process to analyze the stress and strain distribution in the deformed body, and to determine the deformation force and deformation work, so as to reasonably select the tonnage of the equipment and the strength of the mold.
  • ② Study the variation law of component strain and size in the plastic forming process, select the appropriate blank and reasonable intermediate blank shape, so as to optimally achieve the required shape of the component.
  • ③ Study the influence of fabrication conditions such as temperature and strain rate effect on the plastic working resistance of metal and the measures to improve metal toughness and reduce resistance, so as to obtain components with good performance.

The plastic analysis methods of metal forming mainly include principal stress method, slip line method, upper limit method, finite element method, etc.; while the commonly used experimental methods are apparent plastic method and dense grid moiré method.
