It is stamping die in a single process developed on the basis of the integration process more die as a modern production of advanced stamping die, to die in the completion of a complex parts of the punching, flanging, bending, drawing, three-dimensional shape, and so Kind of stamping process, it can be complex shape or parts of the hole, the decomposition of a simple stamping. Stamping, will be expected in raw material or die by the side entrance into, step in the strictly controlled under the conditions of accuracy, according to the order of arrangement forming process, through the work place for stamping, in the final by blanking the place or Cut off, the system can be-products to meet the requirements of the stamping parts. Relatively speaking, multi-progressive die for a single-stamping the process more difficult than a single model to a more simple and therefore can be a complex parts from progressive die stamping, and no one can operate in the circumstances High-speed stamping.Mold can use high-quality, high-intensity, high wear-resistant materials, processing and use of advanced die of CNC tooling equipment and reasonable process. Therefore, the Multi-Position into the mold is highly efficient, high-precision, long-life, safe and reliable operation, processing the characteristics of complex parts, it has become the realization of large-scale production, lower production costs the best choice. It is the contemporary representatives of the advanced stamping die, so by the attention, the application has become more extensive, was designated as the “11th Five-Year Plan“ in the mold of the focus on the development.Contact this subject from the actual production of the subject, the subject is the purpose of the comprehensive use of the professional courses in theory and practical knowledge production, a cold stamping die design of the actual training, so as to nurture and improve their ability to work independently; Seriously study “cold stamping die design“ courses, master cold stamping die design methods and steps; cold stamping die design master the basic skills, such as computing, painting, design information and inspection manuals, familiar with the standards and norms, and so on the basis of Parts plans to design a set of cold stamping die, and production is linked to the actual link.The design standards in the process of stamping die design with actual production, we must first understand the Multi-Position the concept of progressive die, and how it is to work, forming the basic theory, and made it clear that this topic stent Progressive Die The design requirements. And then read to understand the parts of the plan is based on the parts, using the basic theory of stamping and punching through the various check-and progressive die-related information, the parts of materials, structure, accuracy, etc. Process Analysis of the process on the basis of analysis, That, in determining its suitable for stamping on the basis of several viable technology programmes, technical and economic analysis used to identify the best methods of the programme, to finalize a punching - blanking - trimming, packing, Z-shaped bend - bend U, V, L-shaped - Trimming - Trimming stamping process into the programme as the best programme stamping process. In a clear technology options, the overall structure of a mold design, mold, including types of choice, the choice of mode of operation, targeting the choice of ways to discharge the choice, the choice-oriented approach. Then proceed to mold technology and design, this chapter of the brochure is one of the key elements, Including the layout design, calculation and pressure-pressure center, the press and the determination of convex and concave-edge computing principles, calculation methods and specific terms.And then to mold the main components of the design and calculation, including the mold of the main parts of the design and selection and some parts related to the size of calculation and verification, such as determining die size, punch size, identified convex, the structure of die Form, And check its strength, unloading plate thickness of the options and determined that the discharge rubber design, the choice of discharge screw, the use of Dianban and thickness, punch fixed board size and thickness of I. being sold Such as the structure and size of the design, integration and related terms, access to some of the relevant standards from the standard parts,As mentioned, the next-Block, Dianban, discharge board, guided-chu, guided sets, and so on through the above calculation and analysis of the mold that this hand. Finally, there is mold parts of the material.Design principle is in punching, punching, bending progressive die design process, a lot of material collected to study the die design process, a lot of information on the design and stamping die stamping process books and technical information. To study the complex stamping die design elements of each, every part of the design have proved their rationality and assiduously progressive die design process, timely identify problems and find a teacher on.Design of the main technical information available books,the collection of online information resources, training and a self-learning ability of the analysis. For further understanding of the structure of mold, with its working principle and the process is still important. Although only a die design, but through the design of the mold to upgrade their overall capacity of the mechanical design, progressive die design a more in-depth understanding. The actual design and production of the principle of combining, taking into account the processing components of the programme, production volume and other issues, to design the entire mold. Now most parts of the mold has been standardized, a strong proponent of the use of standard mold parts, because of the processing parts of thin, small form factor, die-parts, such as the choice of optional national standards. In addition, plans and parts for assembly with the actual production from the economy and ease of manufacturing areas such as a review and revision. This paper is designed to meet the requirements of the mold, is feasible.目 录目 录设计总说明 .IDESIGN GENERAL INFORMATION .III目 录 .VII第一章 引 言 .11.1 课题的目的意义 .11.2 冲压与冲模的概念 .11.3 冲压成形的特点及应用 .21.4 冲压现状与发展方向 .31.5 冲压的基本工序及模具 .81.6 级进模 .91.6.1 级 进 模 的 概 念 、 特 点 及 应
