The main points of drawing die design, hurry up and collect

Stretching dies occupy a large proportion in the stamping die industry. Most of our commonly used hardware cups, automobile coverings, craft parts, etc. are made by stretching dies. There are too many variables, and some The stretching of non-rotating bodies cannot be designed and manufactured without many years of industry experience; the author introduces some key points for designing stretching dies; The stretching materials are generally made of materials with good tensile properties, such as 8, 08AL, 08F, No. 10 steel, No. 15 steel, No. 20 steel, ST12, ST13, etc.; usually killed rigidity is better than boiling rigidity, but the price is more expensive, depending on the customer's demand; the surface finish of the drawing die, when deep drawing , The die and the blank holder must be ground uniformly, so that the parts are not easy to break and cause scars; The drawing die blank positioning must be designed accurately, our design principle is more wrinkles and less cracks, sometimes thinning and stretching, there is a three-dimensional design software It may not be 100% accurate. It can be corrected by continuous mold testing, and the mold is constantly repaired to reach the final size; each product has the accumulated experience of the mold designer, and it is necessary to choose a high-quality supplier !
