Drawing die: In the case of metal cold stamping books, the "drawing die" is usually the "drawing die" or "stretching mode". In the process of drawing, the parts of the non-spreadable surface are stretched or stretched, so the deep die is also known as tensile or draw-down mode. The drawing die is the norm, and the stretch or pull model is an alias, no difference. The typical structure of a draw-down model The complicated overlays must be double-acting press. This is due to: (1) single action press of the clamping force is not enough, there are air cushion of single action press the clamping force is equal to the pressure of press ~ 25 ~ 20%, and outside of double-action press slider clamping force for the slider pressure within 65% ~ 70%. (2) the clamping force of the single action press can only be the entire adjustment, and double action press slide block outside pressure available outside the four corners of the slider, high and low adjusting nut to adjust, by tilting the slider, adjust the moulding material on each part of the force that press a material, control the flow of the material surface material. The pull of single action press is not enough. (4) single action drawing die of the pressure plate is not rigid, if pressure is expected to face is the three-dimensional curved surface shape, at the beginning of the drawing when bending into pressure burden surface shape because the pressure of material surface shape asymmetry pressure plate deflection, serious when pressure is lost.
The drawing die is also called drawing die, which is used to pull metal plates deep into cups or curved parts. For example, small metal cups or large car body shapes.
The process of making sheet metal material into a bowl or can is called a drawing die. For example, the process equipment that makes the aluminum plate into a can is a kind of pull mold.
Used to pull metal plates deep into cups or curved parts.I hope my answer will help you.
