【正文】 uilding materials and other industrial products, most of the mold will be pleted in more than 50% metal plates, more than 80% of all plastic products, especially through the mold into. 2 The historical development of mold The emergence of mold can be traced back thousands of years ago, pottery and bronze foundry, but the largescale use is with the rise of modern industry and developed. The 19th century, with the arms industry (gun39。s shell), watch industry, radio industry, dies are widely used. After World War II, with the rapid development of world economy, it became a mass production of household appliances, automobiles, electronic equipment, cameras, watches and other parts the best way. From a global perspective, when the United States in the forefront of stamping technology many die of advanced technologies, such as simple mold, high efficiency, mold, die and stamping the high life automation, mostly originated in the United States。 and Switzerland, fine blanking, cold in Germany extrusion technology, plastic processing of the Soviet Union are at the world 39。s, mold industry focus is based on 武漢紡織大學 2021 屆畢業(yè)設計論文 29 subscriber demand, production can meet the product requirements of the mold. Multidie design rule of thumb, reference has been drawing and perceptual knowledge, on the design of mold parts of a lack of real understanding of function. From 1955 to 1965, is the pressure processing of exploration and development of the times the main ponents of the mold and the stress state of the function of a mathematical subbridge, and to continue to apply to onsite practical knowledge to make stamping technology in all aspects of a leap in development. The result is summarized mold design principles, and makes the pressure machine, stamping materials, processing methods, plum with a structure, mold materials, mold manufacturing method, the field of automation devices, a new look to the practical direction of advance, so that pressing processing apparatus capable of producing quality products from the first stage. Into the 7039。s to high speed, launch technology, precision, security, development of the second stage. Continue to emerge in this process a variety of high efficiency, business life, highprecision multifunctional automatic school to help with. Represented by the number of working places as much as other progressive die and dozens of multistation transfer station module. On this basis, has developed both a continuous pressing station there are more slide forming station of the press bending machine. In the meantime, the Japanese stand to the world39。s largest the mold into the micronlevel precision, die life, alloy tool steel mold has reached tens of millions of times, carbide steel mold to each of hundreds of millions of times p minutes for stamping the number of small presses usually 200 to 300, up to 1200 times to 1500 times. In the meantime, in order to meet product updates quickly, with the short duration (such as cars modified, refurbished toys, etc.) need a variety of economictype mold, such as zinc alloy die down, polyurethane rubber mold, die steel skin, also has been very great development. From the mid70s so far can be said that puteraided design, supporting the continuous development of manufacturing technology of the times. With the precision 武漢紡織大學 2021 屆畢業(yè)設計論文 30 and plexity of mold rising, accelerating the production cycle, the mold industry, the quality of equipment and personnel are required to improve. Rely on mon processing equipment, their experience and skills can not meet the needs of mold. Since the 9039。s, mechanical and electronic technologies in close connection with the development of NC machine tools, such as CNC wire cutting machine, CNC EDM, CNC milling, CNC coordinate grinding machine and so on. The use of puter automatic programming, control CNC machine tools to improve the efficiency in the use and scope. In recent years, has developed a puter to timesharing by the way a group of direct management and control of CNC machine tools NNC system With the development of puter technology, puters have gradually into the mold in all areas, including design, manufacturing and management. International Association for the Study of production forecasts to 2021, as a means of links between design and manufacturing drawings will lose its primary role. Automatic Design of die most fundamental point is to establish the mold standard and design standards. To get rid of the people of the past, and practical experience to judge the position of the design center, we must take past experiences and ways of thinking, for series, numerical value, the number of typebased, as the design criteria to the puter store. Components are dry because of mold constitutes a million other differences, to e up with a can adapt to various parts of the design software almost impossible. But some products do not change the shape of parts, mold structure has certain rules, can be summed up for the automatic design of software. If a Japanese pany39。s CDM system for progressive die design and manufacturing, including the importation of parts of the figure, rough start, strip layout, determine the size and standard templates, assembly drawing and parts, the output NC program (for CNC machining Center and line cutting program), etc., used in 20% of the time by hand, reduce their working hours to 35 hours。 from Japan in the early 80s will be threedimensional cad / cam system for automotive panel die. Currently, the physical parts scanning input, 武漢紡織大學 2021 屆畢業(yè)設計論文 31 map lines and data input, geometric form, display, graphics, annotations and the data is automatically programmed, resulting in effective control machine tool control system of postprocessing documents have reached a high level。 puter Simulation
