摘要：模具是能制造出具有一定形状和尺寸的零件的一种成型物品的工具。现如今模具工业已经成为了工业发展的基础工业。在产品生产中的许多阶段，不管是大量生产，批量生产，还是产品的研发试制阶段，目前都越来越倾向于依赖模具的使用。因此模具工业已经成为国民经济的基础工业， 29183
    基于NX制作落料冲孔模的设计是根据零件的形状，以及实际生产中符合实际情况而设计的。在凹凸模的设计中，根据零件的形状，设计线切割3B指令，有快走丝线切割制作。随后经过热处理使得凹凸模的硬度，韧性等物理性能达到模具生产制造的水平。弹簧的数量根据实际生产中能够容纳的一个适合的量，以及满足卸料力和使用的寿命来选择的。压力机，导柱，上下模座等设计配合凹凸模，弹簧力来选择。螺钉，销等选择标准件。基于NX进行了落料冲孔模具的3D图设计，导出装配图。
    此次的设计复合冲裁模的特点：仅有一个工位，当压力机进行一次冲压过程时，在同一个工位上同时完成两道或两道以上冲压工序。效率较高，且不存在二次冲裁时的定位误差。基于NX的3D建图能够提前解决实际生产中时间，成本，质量等问题，在模具生产前解决实际生产中将会遇见的问题，很大程度上节约了成本。

Design of blanking punching die based on NX
Abstract: A mold is a tool for producing a shaped object with a certain shape and size.. Now die industry has become the basic industry of industrial development. In many stages of production, whether mass production, mass production, or product development and trial production stage, it is now more and more inclined to rely on the use of mold. So die industry has become the basic industry of the national economy.,
The design of blanking punching die based on NX is designed according to the shape of the parts, and the actual situation in actual production.. In the design of the bump mold, according to the shape of the parts, the design line cutting 3B instruction, and the production of silk cutting. After heat treatment, the hardness, toughness and other physical properties of the bump die can reach the level of the mould production.. The amount of spring according to the actual production capacity of a suitable amount, as well as the unloading force and the use of life to choose. Press, guide pillar, upper and lower mold block design with concave and convex mold, spring force to choose. Screw, pin, etc selection criteria. The 3D design of blanking punching die based on NX, derived from the assembly drawing.
The characteristics of the design of composite blanking die: only one station, when the press for a stamping process, at the same time to complete two or more than two stamping process. The efficiency is higher, and there is no positioning error in the two time.. Based on NX 3D mapping can advance to solve actual production time, cost, quality and other issues, in front of the mold production to solve actual production will meet the problem, to a large extent cost savings
