Continuous Drawing Die

There are many types of products in the mold industry, of which the stretch mold is one of the higher technical content. The reason why the drawing mold is difficult is that 1, the calculation of the design, and the test work 2 after the mold design is completed.

The calculation method for drawing products with complex shapes will be more troublesome because the shape is also accompanied by changes in material thickness. Even if there is 3D software and simulation analysis software to aid the calculation, it is difficult to achieve the expected material opening effect.

To get the right cut size. Only the cutting edge can be used to determine how much material is needed, and then the structure of the tensile mold is designed to make continuous attempts.

Stretch factor

How many steps are needed to stretch the product? The stretching height and size of each step are calculated by the stretching coefficient. The stretching structure and process are different, and the stretching system is different. Therefore, it is necessary to make a reasonable selection according to the actual product.

4. The main factors affecting the tensile coefficient:

1). Mechanical properties of the material (falling strength --- elastic deformation; tensile strength --- plastic deformation; elongation coefficient; section shrinkage).
