The cold die stamping process is a metal processing method, which is mainly aimed at metal materials. The material is forced to deform or separate through pressure equipment such as a punch press to obtain product parts that meet actual requirements, referred to as stamping parts. There are many situations in the stamping process of a mold, and many friends do not understand this. Here I will summarize the most common stamping procss or everyone. as follows: 1. BlankingA general term for a stamping process that separates materials. It includes blanking, punching, piercing, grooving, cutting, chiseling, trimming, tongue cutting, etc.2. Cutting profile edges and bursIt is mainly to cut off a circle of excess material on the periphery of the material to achieve a stamping process that meets the size requirements3. Cut the tongueA crtain part of the material is cut througha cut butnot allof it i ut. tisually a ecangle that only cutsthee sides and leaves one side intact. The mainfuntin is to i the sep distance.4. FlaringThis process is not common, most of the tubular parts need to be expanded into a trumpet-shaped end or somewhere.5. NechContrary to flaring, it is a stamping process in which the end or a certain part of the tubular part needs to be reduced inward.6. PunchingIn order to obtain the hollow part of the part, the complete material is separated through the punch and the knife edge to obtain the corresponding hole size .7. fine blanking When the stamping parts reqire a full-right section qualit, it can be called "ine blanking" (Note: ordinary blanking sections are divided into four parts: collapsed section, bright section, fractured section, and burr area)8. Full-bright blankingThe difference with fine blanking is that full-bright blanking must obtain full-bright bands in one-step blanking, while fine blanking is not.9. Deep hole punchingWhen the hole diameterin the productis smaller than the thikness of the material, i can be understood as deep hole punching, and the ificulty of punching is manifeted as the puchiseasy to break.10. Convex hulPunch a bump on the flat material to achieve the corresponding use requirements.11. FormingMany friends understand forming as bending, which is not rigorous. Because bending is a type of forming, i rfers to the general term of all fuid material processes during forming.12. BendingA conventional process of plastically deforming flat materials through convex and concave mold inserts to obtain corresponding angles and shapes .13. BeadingThis is generally used in sharp corner bending forming inserts. t is mainly a structure that reduces the rebound of the material by punching the material at the bending position to reduce the rebound of the material and ensure the stability of the angle.14. EmbossingA process of pressing a special pattern on the surface of the material through a punch. Commonly used are: embossing, pitting, etc.15, roll roundA type of molding process is a process of curling the shape of the product into a circle16. Flip holesThe process of turning the inner hole of the stamping part outwards to obtain a certain height of the side17. LevelingMainly for the situato where the flaness of the product is high, when the flatness of he staping patis out of tolerance due to the sres, the eveling process needs to be used for eveling18. ReshapingAter the product is formed, when the angl and shapearenthe therticl si,i is necessary to consider ading a procss forfne-tuning to ensure the stability o he agle. Thi process is called "reshaping" 19, deep drawingUsually refers to the process of obtaining hollow parts from a flat material by a method called the stretching process, which is mainly completed by convex and concave molds20, continuous deep drawing.Usually refers to a stretching process formed by stretching the material at the same position multiple times through one or several molds in a material belt.21, thinning and deepeningContinuous drawing and dep drawing lelon t th thining drawin srs whch mat th la tecest t tat ater i lil e ta th thece ot he materia itself.22. DrawThe pricile is similar t tht of convex hulls, both of which are to emboss the material. However, drawing usually refers to automobile parts, which belong to a more complex forming series, and its drawing structure is also relatively complicated.23. Engineering modelA set of molds that can only complete one stamping process at a time in a stamping process. 24, composite moldA set of molds that can complete two or more different stamping processes in one stamping process. 25, progressive dieA set of molds are fed by the materia belt, and wo or more processes are arranged in sequence, and they are sequentially fed with the stamping process to finall each the general name of the mold type of the qualified product.
