Automatic feeding stamping dies generally have the following special requirements

The automatic feeding device is installed on the metal stamping die to replace the manual feeding operation of the stamping worker. By using the continuous stamping of the ordinary punching machine, the high-speed automatic stamping die can be completed. We call it the automatic feeding stamping die. When using automatic feeding stamping dies for automatic stamping, there are generally the following special requirements: 1. Steel must use small steel strips or long strips of stamping processing dies. Most of us use sheared small-sized materials, but the high-speed stamping If the automatic feeding stamping die is still stamped with small-size materials, then the raw materials need to be replaced frequently, which makes it difficult to exert the high efficiency of automatic stamping. Therefore, the automatic feeding stamping die is suitable for small coils or long strips (above 10m). If the object to be fed is a semi-formed blank, in order to improve the stamping efficiency, it is necessary to sort the parts before sending it. 2. There must be a precise positioning device inside the mold. Due to the limited accuracy of the feeding step of the feeding device attached to the mold, it can only reach ±0.05-±0.1mm at most. Therefore, a precise positioning device must be installed inside the mold to precisely position the feeding step of the feeding device to ensure that the accuracy of the feeding step meets the requirements. Third, the waste or workpiece produced by stamping must be automatically discharged in the continuous stamping state of the punch, and it is impossible and impossible to use manual parts. In order to ensure that the waste or workpieces in the mold are discharged in time, an automatic part ejection device must be installed. In addition, the structure of the cavity in the mold should give priority to the use of a lower discharge cavity with automatic part ejection. Fourth, the stamping parts should be formed in the mold at a time. After the automatic feeding device is attached to the stamping die, the mold manufacturing cost will increase. If the single-process stamping scheme is still used, the stamping efficiency will be effectively improved. Therefore, the stamping parts should be formed at one time in a pair of automatic feeding stamping die, so that the stamping speed is high, which helps to reduce the product cost. 5. The feeding distance should be stable. The feeding distance of the feeding device attached to the automatic feeding stamping die must be stable every time, and if the step distance changes after a long time stamping, it needs to be fine-tuned appropriately.
