⑴. Reasonable mold design. Progressive Die cutting sequence arrangements may affect the precision Stamping. Materials for of stampings small part under generally first arrangement under the larger area of punching material, and then arrange the the smaller areas punching cutting, to mitigate the impact the blanking force of Stamping.
⑵. Suppress material. Overcome the traditional mold design structure in the discharge board out Yung materials gap (ie, when the mold is closed, the stripper plate and die fit and accommodate the material at the discharge board the die gap material thickness t-0.03 ~ 0.05mm). So smooth movement of the stripper plate, stamping, and the material can be pressed. Insert structure, the key to forming parts, stripper plate must be made in order to facilitate the resolution of the long time stamping the lead the stripper plate pressure feed area mill (pressure) loss, and can not be pressed material.
(3) the additional Forced functions. Stripper the insert block nip portion thickened size (normal unloading inserts thick H 0.03mm), in order to increase the pressure on the die side material, thereby suppressing the punching stampings material tumbling, distorted.
⑷. Punch blade end repair beveled or curved. This is an effective way to slow the blanking force. Slow down the blanking force to reduce the tensile force the die side material, and thus inhibit stampings turn over materials, the effect of distortion.
⑸. Daily mold, attention to maintenance punching convex the die edge sharpness. When the punching edge wear, material tensile stress suffered will increase, and thus the stampings turned material, distorted tend to increase.
⑹. The blanking clearance unreasonable or uneven gap also produce stampings tumblebars, twisted reasons, need to be overcome.
