凹落

The secondary mass flux, Z, cavity convergence/divergent angle, and injection angle have different effect on internal performance of DTN.

二次流量、落压比、凹腔扩张角和收敛角、引射角度都对推力矢量状态下的DTN内流性能有着不同的影响。

In order to achieve a tradeoff between vectoring and unvectoring state, the proposed parameters of DTN are: Z=3~4, secondary injection flux is about 3%, cavity divergence angle is about 10°, cavity convergence angle is 20°~30°, injection angle of secondary is about 30° by counterflow injection.

为了实现DTN在推力矢量和非推力矢量下都有较好的内流综合性能，所建议的设计参数为：落压比为3~4，引射量为3%，凹腔扩张角为10°左右，收敛角在20°~30°，引射角度为30°逆流引射角(β=30°)。

Finally, his bed, designed to fit into an alcove in the wall when not being used, yet cursed only to do so when it was, thudded to the floor and Ken was able to sit up.

最后，他的床，进入墙壁的一个凹室之内设计适合当不被使用，然而诅咒不料竟会这麼做当它是的时候，砰地落下到地板而且肯恩能够熬夜。

The press process of blanking,drawing, perforating, flaring, trimming are adopted. In this paper, the process suitability of part is analysed. The process parameters, such as blank layout and press force are calculated. The general construction of mold and main parts are designed. The compound die of blanking,drawing,perforating and the simple press tool of flaring,trimming and detail drawings of main parts are drawn.

设计中分析了工件的冲压工艺性，对毛坯排样、冲压力、刃口尺寸等进行了计算，并且对模具相对应的凸模和凹模进行了强度校核，以及模具总体结构、主要零部件的选择与设计，绘制了落料、拉深、冲孔复合模和翻边、切边的单工序模具装配图和模具的主要零件图。

Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate.

模具的冲孔和落料凸模分别用不同的固定板固定，便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。

In the standard designing procedure of stamping die , the calculation formulas of dimensions of both punch and die plate are derived based on such a principle that for blanking operation to produce the punch with the die plate as the basic part, and for the punching operation to produce the die plate with the punch as the basic part.

在冲裁模设计中，冲裁模的凸模、凹模刃口尺寸计算公式是根据落料以凹模为基准件配制凸模，冲孔以凸模为基准件配制凹模的原则建立的。
