1. Reasonably determine the work steps: the work steps of the continuous mold are equal to the sum of the single steps of decomposition, such as the work steps of punching and blanking continuous mold, usually equal to the sum of two single steps of punching and blanking.However, in order to increase the strength of the punch and facilitate the installation of the punch, it can sometimes be done in several steps according to the number of inner holes.The determination principle of the number of work steps is mainly under the principle of not affecting the strength of the die, the less the number of work steps selected, the better, the less the number of work steps, the smaller the cumulative error, then the workpiece out of the size accuracy is higher.

2, in the punching and blanking process sequence arrangement, the punching process should be placed in front, so that not only can ensure that the material is sent directly, but also can use the punching hole to guide the positioning hole, in order to improve the accuracy of the workpiece.But with some bending after the size or a prominent part of the position into

The position of punching hole should be determined according to the actual size.

3. In the workpiece without circular hole, in order to improve the accuracy of feeding step, the process hole can be designed in the first step sequence of the die, and the precision stamping parts manufacturer can make the process hole as the guide and positioning to improve the accuracy of punching parts.But as the current mold design, we on some precision parts of the stamping has been gradually or all the use of the frame type guide belt.This is beneficial to ensure the machining accuracy of complex workpiece.

4, the same size of the benchmark of the accuracy of higher requirements of different holes, without affecting the strength of the die, should be arranged in the same work step forming.

5, the size of the higher accuracy requirements of the work step, should try to arrange in the last process, and the accuracy requirements are not too high work step, it is better to arrange in the previous process, because the work step is closer to the front, the accumulation of error is greater.

6, in the multi-task step continuous mold, punching, cutting, bending, forming, cutting and other steps of the arrangement sequence, generally should be the separation process such as punching, cutting, cutting groove arrangement in front, then can arrange bending, drawing forming process, and finally arrange cutting and blanking process.

7, punching different shapes and sizes of the porous process, try not to put the big hole and small hole at the same step at the same time, so as to ensure the accuracy of hole spacing when repairing mold.

8. In the design, if the forming and blanking are completed on the same blanking die, the forming punch and blanking punch should be fixed separately, and the surface should not be fixed on the same fixed plate.Precision metal stamping parts as far as possible to form the punch fixed on the board.Add back plate at the back.

9. During the design, the formed part of each working step must not be damaged, and the belt material should be kept on the same feeding line.

10. For the mold with many steps and more bending steps, its concave die edge should adopt the block structure as far as possible to achieve rapid replacement and repair.
