摘要：

以航空仪表视窗零件为例，分析了其冲压工艺性，进行了排样设计及其连续式复合模具总体结构设计，详述了定位装置、卸料装置和工作零件的结构设计。选用了较高精度等级的滑动导向四角导柱钢模板模架，其运作平稳、导向精度高；采用了有沿边、有搭边的排样方式，提高了制件精度；使用双侧刃定距、双侧导料板导向的定位方式，提高了定位精度；采用弹压卸件器和顶件器能够有效防止毛坯偏移，同时提高定位精度，减少回弹；在切舌弯曲和内外缘翻边工位进行了工序复合，减少了定位误差，缩小了模具的整体尺寸，并降低了生产成本；增设空位保证凹模的强度和凸模及其他零件的安装空间。实际生产证明，设计的模具结构加工制造和维护修配简单方便，满足生产效率的要求，能保证产品质量。

Taking the aeronautical meter windows as example，the stamping process of the meter windows was analyzed, the layout and overall structure of multi-position progressive compound die were designed, and the structure design of the location device, strippers and working parts were detailed. Sliding guide four-pillar die sets with higher accuracy grade were selected due to stable operation and high guidance precision. The layout with edgewise and scraps was designed to improve the precision of that part. The location modes of feeding distance determined by double side blades and feeding direction determined by bilateral guide plates were adopted to improve the location precision. The blank offsetting was prevented by using spring strippers and ejectors to improve the location precision and reduce the spring-back at the same time. The location error，overall dimension of die and production costs were reduced by combining cutting tongue-bedding with flanging the inner and outer edges. Some empty stations were added to ensure the strength of die and installing space of the punches and other parts. The actual production shows that the die manufacturing and maintaining are convenient, which meets the required productivity and guarantees the quality.
