冲压模具在实际工业生产中应用广泛，冲压模具的自动送料技术能够极大地提高劳动生产率，减轻工人负担，具有重要的技术进步意义和经济价值。
冲孔和落料的相同点为两个供需的坯料变性分离过程和磨具结构都是一定的。但是，冲孔是在板料上冲出洞，以获得带孔的制件冲裁；落料是为了获得一定的形状和尺寸的落料件，冲落的部分是成品，余下的部分是余料或废料过渡板冲孔落料技术正是利用这两点，在过渡板实现坯料的变形和分离。
本设计使用复合模，用复合模进行一次性冲孔落料，冲压件的的形状精度和尺寸精度容易保证生产效率高，由于零件简单，易加工，选取了YT-130系列压机。使用复合模提高了提高了生产效率，自动化程度.

Answer 1

Stamping die is widely used in actual industrial production, automatic feeding stamping die technology can greatly improve labor productivity, to lighten the burden of workers, the technological progress has the important significance and economic value.
Punching and blanking similarities as both supply and demand of billet degeneration separation process and die structure are certain. But, the punching is out of the hole in the sheet metal, in order to obtain the blanking parts of perforated; Blanking is to obtain a certain shape and size of the materials, rushed down part is finished, the rest of the part is the remaining material or waste transition plate punching blanking technology exploits these two points, the transition plate deformation and separation of billet is achieved.
This design using the composite modulus, using compound die for one-time punching blanking, stamping shape accuracy and dimensional accuracy is easy to ensure high production efficiency, because of its simple parts, easy processing, selected the YT - 130 series pressure machine. Using composite modulus increased the improves the production efficiency, the degree of automation.
