What should be paid attention to in the design of continuous die?

Continuous mold design requires mold parts to have sufficient strength, and the selection of materials must not be wrong. The mold should avoid external convex and concave parts that have nothing to do with the mechanism, and the external edge should be chamfered. In principle, the guide post is installed on the lower mold and away from the operator. The center force of the mold is close to the center line of the mold handle. Important parts such as the guide and positioning must be clearly seen by the operator. The design should take into account the convenience of operation, adjustment, installation, repair, transportation and storage, which is relatively safe for operators. In addition, we usually need to pay attention to the following matters. 1. The number of work steps should be determined reasonably: the number of work steps of the continuous die is equal to the sum of the decomposed single processes; 　　2, when the punching and blanking process sequence is arranged, the punching process should be placed first, which can not only ensure The material is fed directly, and the punched hole can be used as a guide hole to improve the accuracy of the workpiece.　　3. In order to improve the accuracy of the feeding step in the workpiece without circular holes, a process hole can be designed in the first step of the die, so that the process hole can be used as a guide and positioning to improve the accuracy of the punching.　　4. Different holes with higher accuracy requirements of the same size standard should be formed in the same step without affecting the strength of the die.
