The role of double-action drawing presses for drawing parts

Metal stamping factory, processing stainless steel stamping parts, metal drawing parts, metal stamping parts, the outer slider of the double-action drawing press has four suspension points, which can be adjusted by mechanical or hydraulic adjustment methods to adjust the blank holder force at each point to form Forming conditions that are conducive to uniform metal flow in all directions. This is very important for the deep drawing forming of stamping parts with complex shapes. Because of the deep drawing of complex shape stamping parts. Different sections around the blank are required to have different blank holder forces, so that different deformed sections can reach different metal flow resistances, effectively control metal flow, and ensure high-quality hardware deep-drawn stamping parts. 1. The outer slide block of the double-action drawing press has a large blank holder force and good rigidity, which can completely deform the stamping parts at the drawing bead, and can fully play the role of the drawing bead to control the flow of metal, and can also overcome The disadvantage of insufficient blank holder force during deep drawing is used on ordinary presses. 2. When the outer slider of the double-action deep drawing press starts to hold the edge, the outer slider is already at the bottom dead center position, the linkage mechanism is at the collinear position, and the speed of the outer slider is close to zero, so the contact impact with the stamping parts small. During the deep drawing of the inner slide block, the blank holder force of the outer slide block is relatively stable. 3. On the double-action deep-drawing press, the blank holder and the deep-drawing die are both fixed on the backing plate of the worktable, so that the blank is easy to place and position. Since the metal stamping and drawing parts are convex downwards, and the remaining periphery is on the upper part, it is convenient for the manipulator to clamp and feed. 4. When the double-action drawing press is in the drawing work of stamping parts, the movement speed of the inner slide can meet the requirements of drawing deformation speed.
