Matters needing attention in designing continuous stamping die (2)

Precision, the continuous mold production process we use allows multiple processes to be carried out in the same mold, so it has the huge benefit of one-time molding. All high-precision continuous drawing dies are independently developed and manufactured by us. We have already talked about 6 matters that need to be paid attention to when designing continuous stamping dies. There are actually many more things to be noted. We will continue in this article. 1. When punching with multiple punches, the length of the small punch should not be too large. For punching dies with multiple punches, punches of different heights can be made according to the size of the punch, forming a stepped arrangement, which can avoid the punching pressure of each punch At the same time, it can effectively reduce the punching force of the mold. It should be noted that the length of the small punch should not be too large, otherwise problems will occur due to insufficient rigidity. 2. It is not advisable to use rubber or polyurethane rubber as elastic elements in continuous molds and other automatic dies. For continuous molds such as high/efficiency production molds, if rubber and polyurethane elastic elements are used for unloading, on the one hand, the unloading force may be insufficient. Unreliable unloading. On the other hand, their life is limited. In order to ensure the reliable and normal operation of continuous molds and reduce maintenance, a powerful square spring with a life of more than 1 million should generally be used as unloading components. 3. The complicated shape in the continuous stamping die should not be punched out at one time. The complicated shape in the continuous stamping die should not be punched out at one time. It should be broken down into several simple hole shapes and punched in several steps. 4. The continuous drawing die can not ignore the design of the empty station. Continuous drawing is carried out on the long strip material without material annealing and other treatments. It has the characteristics of high production efficiency, labor saving, and automatic stamping. For the continuous drawing die of multi-pass drawing, when designing the layout drawing, one or two empty stations are often left after the first drawing or the first drawing, leaving some leeway so that appropriate changes and changes can be made after the trial. Adjustment. 5. The width of the floating material pin groove of the continuous die should be designed reasonably. In order to make the material feeding accurate and avoid scratching the working surface of the die, generally the coil should be lifted to reduce the feeding resistance. For this reason, side guides are used in the width of the material , Side pressure device and float pin. The side guide plate and the side pressure block are used for the material side positioning of the continuous mold with lower precision, and the floating material pin is used for the material side positioning of the continuous mold with high precision. 6. The discharge plate of the continuous stamping die should not be ignored. The design of the guide device discharge plate (discharge device) is an important content. The poor design of the discharge plate will not only affect the production efficiency of the continuous mold, but also reduce the service life of the continuous mold and increase the maintenance cost. Therefore, the mold designer should pay enough attention to it. [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
