摘 要
冲压是在室温下,利用安装在压力机上的模具对材料施加压力,使其产生分离或塑性变形,从而获得所需零件的一种加工方法。
本设计中所设计的为传统的小型的开式可倾自动压力机,公称压力为20吨,生产效率为40次/分。根据设计的要求,计算冲压功率,确定了以带传动和齿轮传动相结合的二级减速传动方案,,并通过校核,得出了整体的传动系统中的各个部件的精确尺寸和配合关系。在执行机构的设计中,充分考虑压力机对强度和刚度的要求,并进行校核。在对其他的部件设计中,也充分考虑到压力机的要求和特点,比如:选用吸振效能好的材料来作为床身的材料,但也要考虑到经济性要求,以及作为机座的强度和稳定性,在压力机中的传动轴和曲轴中,采用滑动轴承,解决压力机在正常的工作中对轴承的冲击问题,提高压力机精度.

Abstract
Pressing is a kind of processing method under the room temperature which use the mould installed on the pressure machine to add pressure to the material, make it separated or been out of shape, and then abtain the necessary part。
The article designs a traditional small-scale opend automatic pressure machine, standard pressure is 20000kg, production efficiency is 40 times per minite. According to the required of design ,calculate the power of pressing,
then confirm the second moderates transmission combined with gear wheel and belt transmission ,and has carried on analysis and calculation of the size to fix in taking the wheel and gear wheel。 Through strength analyse confirm drive shaft and bent axle of every size and material, and then through checking, abtain the accurate size and cooperating with the relation of each part drawn in the transmission of the whole. In the design of the executive body, fully consider the requisition for intensity and rigidity of the pressure machine, and then check it. To other parts design, fully consider the demand and characteristic of pressure machine too, for example: Select the good suck and shake material as the material of the lathe bed, but must consider the economy required, and the intensity and stability of the regarding as machine drive shaft and bent axle in the pressing machine, adopt the slip bearing ,to solve the impact problem of pressing to the bearing of normal work, and to improve the precision of t
