Abstract
Along with the modern industry swift and violent development, cutting mold technology obtains the more and more widespread application. This design was aims at t aircraft fuel tanks fueling nozzle place to carry on cutting mold design, including Blanking, drawing compound mold, the second drawing mold, drawing Piercing mold. First, carrying on the detailed craft analysis to the product, the reasonable craft plan has determined ; Next, according to the blanking components formation principle, the basic mold structure and the removing process and the principle of design, has carried on the process design to main effective parts, and has chosen some related components according to the standard; later has carried on the essential examination computation to the work components and the press specification; Finally, draws up the mold the assembly drawing and the partial detail drawings. The structure of the introduced example mold in this article is simple practical, easy to operate reliable, may guarantee the mold work movement to be reliable and the pressing part mass production request, has the certain reference function to the similar work piece mass production.
