Custom Stamping Stamping is the use of a die to make various sheet-like parts, shells, and container-like workpieces from sheet metal on a press, or to make pipe fittings into various tubular workpieces. This kind of forming process in the cold state is called cold stamping or stamping for short. Metal stamping, also known as pressing, is a low-cost, high-speed manufacturing process that can produce a large number of identical metal parts. The stamping operation is suitable for short-term or long-term production, can be carried out together with other metal forming operations, and can be composed of one or more of a series of more specific processes or technologies, such as Punching Blanking Embossing Coining Bending Flanging Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness, and strength. Stamping can produce workpieces with stiffeners, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach the micron level, the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched out. Cold stamping parts are generally no longer processed by cutting, or only a small amount of cutting processing is required. The precision and surface condition of hot stamping parts are lower than cold stamping parts but still better than castings and forgings, and the cutting amount is less. There are many situations in the stamping process of the mold, the most common stamping process. as follows: 1. Blanking; A general term for a stamping process that separates materials. It includes blanking, punching, punching, grooving, sectioning, chisel cutting, edge trimming, tongue cutting, cutting, etc. 2. Making shape; It is mainly a stamping process that cuts off a circle of excess material around the material to meet the size requirements. 3. Cutting tongue; A certain part of the material is cut into a hole, but not all of it is cut. It is common that only three sides of the rectangle are cut and one side is left untouched. The main function is to set the step distance. 4. Flaring; This process is uncommon, mostly for tubular parts that need to expand the end or somewhere outward into a trumpet shape 5. Necking; Just the opposite of flaring, it is a stamping process in which a tubular part needs to be narrowed inward at the end or somewhere. 6. Punching; In order to obtain the hollow part of the part, the corresponding hole size is obtained by separating the material through the punch and the knife-edge in the middle of the complete material. 7. Precision stamping; When the stamping part requires a full bright band, it can be called "precision stamping". 8. Full Bright Blanking; Unlike precision stamping, full-bright punching must obtain a full-bright band in one-step punching, while precision stamping is not. 9. Deep hole punching; When the hole diameter in the product is smaller than the material thickness, it can be understood as deep hole punching, and the punching difficulty is that the punch is easy to break. 10. Making convex hull; A protrusion is punched on the flat material to perform the corresponding process of use. 11. Forming shape; Many friends understand forming as bending, which is not rigorous. Because bending is a type of forming, forming refers to the general term for all fluid material processes. 12. Bending; A conventional process in which the corresponding angle and shape are obtained by plastically deforming the flat material through the convex and concave die inserts. 13. Beading; This is generally used in sharp-angle bending forming inserts, mainly by punching convex pits in the material at the bending position to reduce material rebound and ensure a stable angle. 14. Coining; A process in which a special pattern is pressed on the surface of the material through a punch. Commonly include embossing, pitting, etc. 15. Rounding; One of the molding processes is a process in which the shape of the product is curled into a circle. 16. Hole flanging; The process of inverting the inner hole of the stamping part to obtain a side edge of a certain height. 17. Leveling It is mainly aimed at the situation where the product flatness is required to be high. When the flatness of the stamping part is out of tolerance due to stress, the leveling process needs to be used for leveling. 18. Shaping; After the product is formed, if the angle and shape are not the theoretical sizes, it is necessary to consider adding a process for fine-tuning to ensure the stability of the angle. This process is called "shaping". 19. Deep drawing; It usually refers to the process of obtaining hollow parts from flat materials by a method, which is called the stretching process, which is mainly completed by convex and concave molds. 20. Continuous deep-drawing; Usually refers to a stretching process formed by stretching the material in the same position multiple times through one or several dies in a material belt. 21. Thinning and deep drawing; Continuous drawing and deep drawing belong to the thinning drawing series, which means that the wall thickness of the drawn part will be less than the thickness of the material itself. 22. Mandrelling; The principle is similar to that of the convex hull, which is to make the material convex. However, drawing usually refers to automobile parts, which belong to a relatively complex-forming series, and its drawing structure is also relatively complex. The history of the stamping process. In 1890, stamped bicycle parts were imported from Germany to the United States, and American companies then began to have stamping machines made by American machine tool manufacturers to manufacture most bicycle parts through research and development of western wheel stamping. Several automakers adopted stampings before Ford Motor Company. Henry Ford had rejected his engineer's suggestion to use stamped parts, but because the company could not meet the demand for die forgings, Ford had to use stamped parts. The advantages of the stamping process. 1. Compared with wire cutting, cold stamping has a series of advantages such as high production efficiency, low processing cost, high material utilization rate, stable product dimensional accuracy, simple operation, and easy mechanization and automation, and is especially suitable for mass production. As a very important processing method in modern industry, stamping die forming is used to produce various sheet metal parts. It has many unique advantages. The formed parts have lightweight, have high rigidity, high strength, good interchangeability, and low cost. , The production process is easy to achieve mechanical automation and high production efficiency. It is an advanced manufacturing technology that cannot be compared and is irreplaceable by other processing methods. It has strong competitiveness in the manufacturing industry and is widely used in automobiles, energy, In the production of machinery, information, the aerospace, the defense industry, and daily life. 2. After absorbing the knowledge of mechanics, mathematics, metal material science, mechanical science and control, computer technology, etc., the basic theory of forming stamping discipline has been formed. With stamping products as the leader, mold as the center, combined with modern advanced technology 3. The application of technology, stimulated and promoted by the huge market demand for products, stamping technology plays an increasingly important role in the development of the national economy, the realization of modernization, and the improvement of people's living standards. 4. Modern stamping die production is a manufacturing method that continues to operate on a large scale. Due to the participation and intervention of high-tech, the stamping production method has gradually evolved from the initial manual operation to integrated manufacturing. The production process is gradually realized through mechanization and automation and is developing in the direction of intelligence and integration. Die Master WeChat: mujuren realizes automatic stamping operation, which reflects the advantages of safety, high efficiency, and material saving. It has become the development direction of stamping die production. 5. Many utensils used by people in daily life are made by stamping method, such as stainless steel rice bowl, which is punched out by using a circular metal sheet on a press machine and using a die to pressurize the circular sheet. It can be seen that cold stamping is a metal pressure processing method that uses a die to apply pressure on a press to separate or deform various metal (or non-metal) sheets at room temperature (cold state) to obtain parts of a certain shape.
