Characteristics of fine blanking parts

The working principle of fine blanking parts processing is: in the three action press, with the help of the special structure of the fine blanking die, under the action of strong force, the material produces plastic shear deformation, so as to obtain high-quality parts.
High quality fine blanking parts are characterized by smooth blanking surface, high dimensional accuracy and high flatness. After deburring, the assembly can be carried out directly without cutting, cutting, grinding, straightening and other processing procedures required after common stamping, which saves a lot of investment in auxiliary equipment, manpower, material resources and operating costs, not only improves the production efficiency, but also avoids the accuracy loss of each process, and ensures the repeated accuracy and production reliability of mass production parts.
The main application field of precision stamping is automobile parts. Modern car industry enjoys all the performance advantages of fine blanking parts. There are at least 40 kinds of fine blanking parts in each car. According to this trend, MS stamping devotes itself to precision stamping parts of automobile. C2680, 6.5mm spacing, ± 0.02mm dimension tolerance, + / – 0.05mm straightness and + / – 0.05mm perpendicularity are commonly used for precision stamping parts of automobile. The stamping speed can reach 1500spm.
