Stamping die is an essential process equipment for stamping production, and it is a technology intensive product. The quality, production efficiency and production cost of stamping parts are directly related to mold design and manufacture. The level of mold design and manufacturing technology is one of the important marks to measure the level of a country's product manufacturing level. To a great extent, it determines the quality, benefit and the development ability of the new product. There are several principles to be followed for the selection of stamping dies.
(1) for the outline that can be classified into the basic figure, first search the die library to find out whether there is a completely consistent outline and a stamping die that can be washed out of the outline with a punching action. If there is such a mold, it will be ignored in the selection of stamping die under the setting of the stamping die, the use of the search directly to the stamping die.
2. For rectangular outline, when long edge is greater than or equal to 1 of short edge. At 5 times, it will automatically search for a square punching die that is consistent with a rectangular short side: a circular stamping die that searches for a long circular groove or a circular slot with the same groove width, and if the die is used directly. After the above two steps have not yet been determined, the straight-line or circular arc should be considered with a square die or a circular die.
(3) first consider the setting of the punching die under the selection of the stamping die, and analyze whether the straight line to be stamped is larger than or equal to 1 of the length of the die. 5 times, when the inner diameter of the stamping die is analyzed, the diameter of the arc to be stamped is larger than that of the die. If you use the set punching die.
(4) if the punching die is not suitable, the system will search the square or circular punch die from small to large in the stamping die library, and use 1 of the straight line to meet the stamping or equal to the length of the 1.5 times.
