Development of precision stamping parts
The level of precision stamping parts of stamping dies has been greatly improved in China. Large mold has been able to produce a single set of more than 50 tons of mold. It can be used to produce automobile matching cover parts. The precision is 1 ~ 2 μ m, about 2 million domestic enterprises have been able to produce multi position progressive die for life. The fine blanking dies with surface roughness Ra ≤ 1.5 μ m, large size fine dies (φ ≥ 300 mm) and plate fine blanking dies have also reached a very high level.
Design process of multi position progressive die
The structure of multi position progressive die is generally complex, and its complexity varies with the complexity. The products are simple, the progressive die is also simple, the parts are complex, and the structure of the progressive die is also complex, and the cost is of course high. Therefore, in the design of progressive die, we must be careful, careful and careful consideration of each link, the progressive die design.
In short, the design step of progressive die is the work sequence that the Designer completes the mold drawing after receiving the task. Because of the different tools and methods used in the design, advanced CAD can be used for design, and some of them can only be designed by drawing board. However, no matter what method is adopted, the purpose and result are consistent, that is, less time is needed to design economical and practical multi position progressive die with the best quality
