空调内机挡风板冲压工艺分析及模具设计（本科毕业论文设计）,摘要空调内机挡风板是空调内部一个重要的组成件，它位于风扇的上侧与蒸发器的下侧之间。挡风板尺寸较大，板体两侧有孔、周边有多处缺口和竖边。要求制件的高度差不可过大，以保证与空调机身的配合。挡风板的这些特点决定了其成形的复杂性和工艺方案的多样性。论文分析了空调内机挡风板产品特点及冲压工艺性。根据冲压理论知识，对挡风板冲压工艺...

ABSTRACT
The wind-board of air-conditioner is an important component inside the air-conditioner, it is between the upper side of the fan and the lower side of the plate body. The wind-board is a litter larger; there are some holes on both sides of the body panel. A number of gaps and vertical edges surrounding the wind-board. It demands that the high-low deflection of its periphery not too big. These features of the wind-board make the forming process complicated and the processing plans various.
This paper analyses the features and the stamping process of the wind-board of air-conditioner. According to the theoretical knowledge of stamping, this paper analyzes and compares its forming processes plans. Use of numerical simulation, wind-board forming process is simulated. According to the analysis of the simulation results, this paper forecasts possible vulnerabilities, so as to take measures to avoid defects in the actual production process. The paper designs forming die and blanking-piercing compound die use of the knowledge of mould design. calculates the key process parameters and corresponding working size, accomplishes assembly drawing of forming die and blanking-piercing compound die, as well as part drawing of key accessories in the dies.
