【正文】 rocess model in a press tour, just pleted a die stamping process. (2) posite model is only one station, in a press tour, at the same station at the same time to plete more than two or two die stamping process. (3) Progressive Die (also known as the modulus of continuity) in the feeding direction, rough, with two or more of the station, at the press of a visit, work in different places on the pletion of two or two successive Road over stamping die process. Chong called cold stamping die Diewide. Cold stamping die is used in cold stamping die mold industry, and accessories required for highperformance structural ceramic materials, preparation methods, highperformance ceramic materials, molds and accessories from the zirconium oxide and yttrium aluminum powder increases, Pr element position, Preparation is the solution of zirconia, yttria solution, praseodymium oxide solution, according to a certain percentage of alumina solution when mixed liquor, ammonium bicarbonate infusion, by coprecipitation synthesis of ceramic materials, molds and accessories needed for raw materials, reaction precipitate generated by the treatment, drying, calcining and accessories by high performance ceramic mold material superfine powder, and then after forming, sintering, finishing, they will have highperformance ceramic materials, molds and accessories. Advantages of this invention is the invention made of cold stamping dies and parts and long service life, the process does not appear in the press and its parts and stamping die bond generated the phenomenon of stamping surface is smooth, no glitches, can replace traditional highspeed steel, tungsten steel. Die with the main parts Die stamping tools is the main process equipment, stamping rely on the relative movement under the mold pleted. Processing time because the upper and lower mold between the constant division and, if continued operation of the fingers of workers to enter or remain in the mold closed, there will certainly pose a serious threat to their personal safety. (A) of the mold main parts, function and safety requirements 1. Working parts is a direct punch to blank forming the working parts, therefore, it is the key to mold parts. Punch not only sophisticated and plex, it should meet the following requirements: (1) be of sufficient strength, can not be broken or destroyed during stamping. (2) should be appropriate to its material and heat treatment requirements, to prevent too high hardness and brittle fracture. 2. Positioning parts positioning part is to determine the location of the parts installed blank, there are pins (board), gauge pin (plate), lead is sold, guide plate, knife set from the side, side pressure etc.. Design should be considered when positioning parts easy to operate and should not have had orientation, location to facilitate observation, preferably in the forward position, contouring to correct the pin location and positioning. 3. Binder, unloading and discharging parts binder ponents are blank holder, binder board. Blank holder pressure can drawing blank holder force, thereby preventing billets under the action of the tangential pressure arch formed folds. The role of pressure plate to prevent movement and bounce blank. Top of the device, discharge board39。s manufacturing sector has bee an important symbol of the level, and largely determine the viability of enterprises. Die with enterprises to increase in recent years many technological advances for investment, technological progress will be seen as an important driving force for enterprise development. Some domestic enterprises have popularized the twodimensional mold CAD, and gradually began to use UG, Pro / Engineer, IDEAS, EuclidIS and other international mon software, individual manufacturers have also introduced Moldflow, CFlow, DYNAFORM, Optris and MAGMASOFT etc. CAE software, and successfully applied in stamping die design. A car cover mold as the representative of a large stamping die manufacturing technology has made great progress, Dongfeng Motor Corporation mold factory, mold manufacturers such as FAW mold center has been able to produce some car cover mold. In addition, many research institutions and universities to carry out technology research and development of mold. After years of effort, in the mold CAD / CAE / CAM technology has made remarkable progress。 both the general accuracy of product production, but also can produce precision parts. Should pay attention to development such as fine blanking (especially thick material fine blanking), forming highenergy, soft mold forming, pressure and processing new superplastic forming process, but also promote the easy mode (soft mode and the low melting point alloy mold), Universal Hybrid model, the use of CNC punch press and other equipment. In addition, the performance improvement of sheet metal stamping, mold new material, die development of new processing methods should be further strengthened. Die with life and Countermeasures Die with the life of the workpiece by punching out the number of terms. Many factors affect the life Die. There are die structure design, manufacture molds used in the punch and die materials, die quality and surface hardening heat treatment, precision die manufacturing parts and cold stamping materials sel
