About Deep Drawing Die
The die used for drawing is called a drawing die, and a drawing die is a special tool for batch processing of materials (metal or non-metal) into the desired punching parts. There are many types of drawing dies. According to the combination, they can be divided into single-process drawing dies, compound dies and progressive drawing dies. Divided by stamping equipment, it can also be divided into drawing dies for single-acting presses, drawing dies for double-acting presses and drawing dies for three-acting presses. The main condition for distinguishing the three is the difference in the blank holder (elastic blank holder and rigid blank holder). The drawing die can also be divided into the first drawing die and the subsequent drawing die. The main difference between them is the difference in the structure and positioning of the blank holder.
Regarding the thinning drawing die, thinning drawing is very different from general drawing. The characteristic of thinning drawing is that the diameter of the drawn part changes relatively little, the thickness of the bottom end of the workpiece does not change, and the side wall of the workpiece does not change. Thickness becomes thinner in the process of deep drawing, and the height of the workpiece increases accordingly. In thinning drawing die, when the punch is punched down, it passes through the die (two pieces), and the blank is thinned and drawn twice. When the punch rises, the unloading ring block unloads the deep drawing from the punch.
There is also a reverse drawing die. The working principle of the square drawing die is to turn the inner wall of the workpiece eversion, and the contact surface between the workpiece and the die is large. Due to the large dynamic resistance of the workpiece material, the pressing ring can be omitted. Since the outer diameter of the die is smaller than the inner diameter of the process part, the tensile coefficient of all reverse stretching should not be too large. If it is too large, the wall thickness of the die will be too thin and the strength will be insufficient.
