空調(diào)內(nèi)機(jī)擋風(fēng)板沖壓工藝分析及模具設(shè)計(jì)（本科畢業(yè)論文設(shè)計(jì)）,摘要空調(diào)內(nèi)機(jī)擋風(fēng)板是空調(diào)內(nèi)部一個(gè)重要的組成件，它位于風(fēng)扇的上側(cè)與蒸發(fā)器的下側(cè)之間。擋風(fēng)板尺寸較大，板體兩側(cè)有孔、周邊有多處缺口和豎邊。要求制件的高度差不可過大，以保證與空調(diào)機(jī)身的配合。擋風(fēng)板的這些特點(diǎn)決定了其成形的復(fù)雜性和工藝方案的多樣性。論文分析了空調(diào)內(nèi)機(jī)擋風(fēng)板產(chǎn)品特點(diǎn)及沖壓工藝性。根據(jù)沖壓理論知識(shí)，對(duì)擋風(fēng)板沖壓工藝...

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.
