【正文】 ty Die can guarantee that the plex should be subinspection blanking. For workers, such as bending and forming, and should consider the possibility of a shape, if not sure, should be increased step by step top shape or space to facilitate adjustment tool. Requirements for flatness or warpage shape is easy to form the products, should increase the schoolsite level to ensure flatness. Layout design, the material can be in ensuring a smooth and stable into the premise of the production should be expected to reduce the step width and to reduce the cost of sheet metal parts. insert design blanking punch Blanking punch shape is determined by the shape of products, it can be used straight body structure of the structure can be enhanced. The way the major fixed: hang stationary, fixed pins, screws. Press the fixed, fixedwire top. This fixed most of them linked to Taiwan safe and reliable, are not monly used fixed pin, the other three kinds of fixation methods is to facilitate the rapid replacement of maintenance. Can choose freely. Die directly on the concave edge can cut out the template, but for the production of larger or higher hardness products, should be designed die insert to facilitate maintenance. Die insert a fixed way: hanging stationary, screw fixed, fixedPress. Unilateral red in the design of the die cut insert, the surface to prevent the generation of waste should not be punching the side of the cusp is expected to increase congestion, crowded living waste from its surface. Template design Progressive Die standard templates include: discharge board, a fixed plate, concave template, on the mold base, the mold base. Which the discharge plate and fixed plate, Au is the key of the three template template, is essential for progressive die. Fixed plate fixed to play the role of punch。 discharge discharge from the main board, orientation, the role of binder in three。 Au template can serve as die cutting, or for the die insert. Between the three template column with four small introduction to the guide, the four small lead column fixed fixed chess board in the convex, concave in the discharge plate and insert a template, respectively, four small lead honey, precise control of small columns and I. Introduction of a small suite with precision in order to ensure the accuracy of punch movement. Progressive Die for the design, there is a very important way is to design, bending or forming, such as the general position of all the followup work place needs to give way, and to fully make way, make way to consider not only static but also whether there is a need to consider dynamic way. Design of other Parts Progressive Die in some parts of the mold supporting the smooth progress of the work also plays an important role. (1) guide is nailed. Progressive Die in China, introduction of products are nail had a greater impact on accuracy, the general position in the first two red holes, place the followup work carried out by the twohole twodirection, this can guarantee a better product accuracy. Design guidelines are being nailed to the attention of the control guide is the length of nails, when the mold in a free state guide arm is part of the nail plate extending the length of discharge less than the product a thick material so that you can effectively avoid material phenomena. (2) block and push up feed. When the material to be bent, cut the door, stretching and other forming processes, we will have a package so tight power metal forming parts of articles in the package insert on tight and difficult to release. In order to ensure a smooth feed up article, the design should be carried in a suitable position or push block material, and relying on the spring force is expected top be a plum. In the final position, the products are sometimes cut off because the role of the oil press in the mold on the adhesion, so the final position the upper and lower mold mandrel should be designed to prevent the phenomenon of overlapping pieces and mold damage. In addition, in order to prevent misuse and waste feed mold surface damage phenomenon, the design error can feed and waste floating alarm sensors. 3, Conclusion Design is the source of mold design while only about 10% of the cost, but decided the cost of the entire mold 80% 70%, so when designers must consider the mold structure in detail, consider raising the productivity, to facilitate the maintenance . However, they can not be pletely dependent on the design to the actual production and analysis of specific issues, according to the actual situation of mold adjustment is necessary. In the production of mold repair and maintenance is very important. In the mold maintenance. Should pay more attention to details, identify the root causes cited for its maintenance. Mold in the disassembly, it is necessary to carefully to prevent injury in a touch. Regular maintenance, maintenance can greatly enhance the life of mold.謝辭
