圆形垫片冲压模具设计

垫片冲压模具设计

摘要

本次设计了一套落料、冲孔的模具。经过查阅资料，首先要对零件进行工艺分析。经过工艺分析和对比，采用落料、冲孔工序。通过冲裁力、顶件力、卸料力等计算，确定压力机的型号。再分析对冲压件加工的模具适用类型选择所需设计的模具。得出将设计的模具类型后将模具的各工作零部件设计过程表达出来。

在文档中第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性与本次设计的意义，接着是对冲压件的工艺分析，完成了工艺方案的确定。第二部分，对零件排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算，对选择冲压设备提供依据。最后对主要零部件的设计和标准件的选择，为本次设计模具的绘制和模具的成形提供依据，以及为装配图各尺寸提供依据。通过前面的设计方案画出模具各零件图和装配图。

本次设计阐述了冲压倒装复合模的结构设计及工作过程。本模具性能可靠，运行平稳，提高了产品质量和生产效率，降低劳动强度和生产成本。

GASKET STAMPING MOULD DESIGN

ABSTRACT

The design of a set of blanking and punching mold. Through referring to information, first of all, I should analysis the process. Through process analysis and comparison, I use blanking and punching process. Through the blanking force, the top piece, and the discharge power to determine the model press. Further analysis of the stamping dies for processing the application to select the desired type of mold design. The mold will be designed to draw upon the type of mold parts of the work expressed in the design process.

In the first part of the document mainly describes the development of stamping die, stamping die illustrate the importance and significance of this design, and then stamping parts of the process analysis, completed a process to identify programs. The second part of the nesting parts of the design plans to complete the calculation of the utilization of the material further edge blanking process of calculation and Die Design and Calculation of the work of some of the stamping equipment to provide a basis to choose. Finally, the main components of standard design and the choice of design-based mapping tool and provide a basis for forming mold, as well as the assembly drawing to provide the basis of the size. Through the draw in front of mold design and assembly of the parts diagram Fig.

The design tells the structure of compound mold design and working process. Reliable performance of the mold, smooth running, improved product quality and production efficiency, reduce labor intensity and production costs.

Key words: Blanking, Punching, Mold, Mold gap
