Claim 4:
5. An impact forming method for local small features on a metal thin-walled curved-surface part based on an impact forming device for forming local small features on a metal thin-walled curved-surface part according to claim 1, comprising the following steps:
S1, analyzing an overall shape of the metal thin-walled curved-surface part and local small features intended to be formed, and designing and machining the forming supporting die and the impact forming dies;
S2, supporting and fixing the metal thin-walled curved-surface part without forming local small features by using the forming supporting die; and
S3, applying the instantaneous impact load to the impact forming die by using the impact loading unit, and impacting the metal thin-walled curved-surface part by the impact forming parts to complete the impact forming of the local small features.
