Introduction
In the current fierce market competition, the product to market sooner or later is often the key to the success or failure. Mould is a product of high quality, high efficiency production tool, mold development cycle of the main part of the product development cycle. So the customer requirements for mold development cycle shorter, many customers put the mould delivery date in the first place, and then the quality and price. Therefore, how to ensure the quality, control the cost under the premi of processing mould is a problem worthy of rious consideration. Mold processing technology is an advanced manufacturing technology, has become an important development direction, in the aerospace, automotive, machinery and other industries widely ud. Mold processing technology, can improve the comprehensive benefit and competitiveness of manufacturing industry. Rearch and esta

1. The concept, characteristics and application of stamping
Stamping is a pressure processing method that us a mold installed on a press machine (mainly a press) to apply pressure to a material to cau it to parate or plastically deform, thereby obtaining a desired part (commonly referred to as a stamped or stamped part). Stamping is usually cold deformation processing of the material at room temperature, and the main u of sheet metal to form denso
the required parts, it is also called cold stamping or sheet metal stamping. Stamping is one of the main methods of material pressure processing or plastic processing, and is affiliated with material forming engineering.
The stamping die is called stamping die, or die. Dies are special tools for the batch processing of materials (metal or non-metallic) into the required stampings. Stamping is critical in stamping. There is no die that meets the requirements. Batch stamping production is difficult. Without advanced stamping, advanced stamping process cannot be achieved.

Stamping process and dies, stamping equipment, and stamping materials constitute the three elements of stamping. Only when they are combined can stampings be obtained.

sakura是什么意思Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects, and its main performance is as follows;
英语学习视频教程(1) The stamping process has high production efficiency, easy operation, and easy realization of mechanization and automation. This is becau stamping is accomplished by means of die and punching equipment. The number of strokes for ordinary press can reach veral tens of times per
minute, and the high-speed pressure can reach hundreds or even thousands of times per minute, and each press stroke is Y ou may get a punch.
(2) Since the die ensures the dimensional and shape accuracy of the stamping part during stamping, and generally does not destroy the surface quality of the stamping part, the life of the die is generally longer, so the stamping quality is stable, the interc hangeability is good, and it has “the same” Characteristics.
(3) Stamping can process parts with a wide range of sizes and shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, coverings, etc., plus the cold deformation hardening effect of materials during stamping, the strength of stamping and The
stiffness is high.
(4) Stamping generally does not generate scraps, material consumption is less, and no other heating equipment is required. Therefore, it is a material-saving and energy-saving processing method, and the cost of stamping parts is low.
However, the molds ud for stamping are generally specialized, and sometimes a complex part req
uires veral ts of molds for forming, and the precision of the mold manufacturing is high and the technical requirements are high. It is a technology-intensive product. Therefore, the advantages of stamping can only be fully realized in the ca of large production volume of stamping parts, so as to obtain better economic benefits.
Stamping is widely ud in modern industrial production, especially in mass production. A considerable number of industrial ctors are increasingly using punching to process product components such as automobiles, agricultural machinery, instruments, meters, electronics, aerospace, aerospace, home appliances, and light industry. In the industrial ctors, the proportion of stamped parts is quite large, at least 60% or more, and more than 90%. Many of the parts that were manufactured in the past using forging = casting and cutting process are now mostly replaced by light-weight, rigid stampings. Therefore, it can be said that if the stamping process cannot be adopted in production, it is
difficult for many industrial departments to increa the production efficiency and product quality, reduce the production cost, and quickly replace the product.

audacity
Due to the wide variety of stamped parts and the different shapes, sizes, and precision requirements of various parts, the stamping process ud in production is also varied. Summarized, can be divided into two major categories of paration process and forming process; Separation process is to make the blank along a certain contour line to obtain a certain shape, size and ction quality stamping (commonly referred to as blanking parts) of the process; forming process refers to The process of producing a stamped part of a certain shape and size by plastic deformation of the blank without breaking.
The above two types of process can be divided into four basic process: blanking, bending, deep drawing and forming according to different basic deformation modes. Each basic process also includes multiple single process.
In actual production, when the production volume of the stamped part is large, the size is small and the tolerance requirement is small, it is not economical or even difficult to achieve the requirement if the stamping is performed in a single process. At this time, a centralized scheme is mostly ud in the process, that is, two or more single
