Cold stamping die process is a metal processing method, which is mainly for metal materials, through the press and other pressure equipment to force the material to deform or separate, in order to get to meet the actual requirements of the product parts, referred to as: stamping parts.
Mold stamping process has a variety of situations, many friends said they do not quite understand, here to summarize the most common stamping process. As follows:
1, punching the material will be separated from the general term of a stamping process. It includes: drop, punching, punching, punching, slotting, cutting, chiseling, cutting, cutting edge, cutting tongue, cutting, etc.
2, under the shape of the main material is cut off the periphery of a circle of excess material to meet the size requirements of the stamping process
3, cut the tongue of a part of the material to cut a mouth, but not all cut, common for rectangular only cut three sides and keep one side does not move, the main role of the fixed step distance.
4, expanding the mouth of this process is not common, mostly for tubular parts need to expand the end or somewhere outward for the trumpet-like situation
5, shrinking and flaring just the opposite, is a tube-shaped parts need to be the end or somewhere inward to reduce a stamping process
6、Punching in order to get the hollow part of the part, the complete material in the middle through the punch and the knife will be separated from the material to get the corresponding hole size.
7、Fine punching when the stamped parts need to section quality for the full bright band, it can be called “fine punching” (Note: ordinary punching section is divided into: collapsed corner of the band, bright band, fracture zone, burr area of the four parts)
8, full bright punching and fine punching is different from the full bright punching must be in a step of punching to get a full bright band and fine punching is not
9、Deep hole punching when the hole diameter in the product is smaller than the thickness of the material can be understood as deep hole punching, the punching difficulty is manifested in the punch is easy to break.
10, playing convex package in the flat material to play a raised and play a corresponding use of the required process
11, forming many friends understand the molding into bending, which is not rigorous. Because bending is a type of molding, molding refers to all the fluidity of the material process of the general term
12, bending the flat material through the convex and concave mold inserts for plastic deformation after the corresponding angle, shape of a conventional process
13、Pressure rib which is generally used for sharp corner bending molding inserts, mainly through the bending position of the material to play a convex pit to reduce the rebound of the material to ensure the stability of the angle of a structure
14, embossing on the surface of the material through the punch to press out a special pattern of a process, common are: embossed words, pockmarks and so on.
15、Rolling a round molding process, is a process of curling the product shape into a round shape.
16、Turning the hole will be stamped inside the hole and get a certain height of the side of the process
17、Smoothing is mainly for products with high flatness requirements, when the stamped parts due to the stress of the flatness exceeds the need to use the smoothing process for smoothing
18、Shaping when the product molding is completed, the angle, the shape is not the theoretical size, it is necessary to consider adding a process to ensure that the angle of fine-tuning to ensure stability, this process is known as “shaping”.
19, deep-drawing usually refers to the flat material through the method to get the hollow parts of the process is called stretching process, mainly through the convex and concave mold to complete
20、Continuous deep drawing usually refers to a material belt, through a pair or several molds will be the same position of the material is stretched several times and the formation of a stretching process
21, thinning deep drawing continuous stretching, deep drawing belongs to the thinning stretching series, refers to the wall thickness of the stretched parts will be less than the thickness of the material itself
22, the principle of stretching and convex package is similar to the material will be convex. However, stretching usually refers to automotive parts, belongs to the more complex molding series, the structure of its stretching is relatively complex.
23, engineering mold a set of molds in a stamping process can only complete a stamping process mold collectively referred to as the
24, composite mold a set of molds in a stamping process can be completed in two or more different stamping process mold collectively referred to as
25, progressive mold a set of mold by the material belt feed, more than two kinds of processes sequentially arranged up, with the stamping process in order to feed to the final qualified product mold type general term.
