Lead core delay element end face cutting apparatus with high precision

The utility model belongs to the technical field of an initiating explosive product manufacturing apparatus and concretely relates to a lead core delay element end face cutting apparatus with high precision. The apparatus mainly solves technical problems that initiating explosive products possess low guide explosion delay time control precision due to uneasy control of guide explosion delay time of the present lead core. The lead core delay element end face cutting apparatus with high precision comprises a jack air cylinder, an installation rack, a spacing rack (a), a return stroke pneumatic control valve (A), a return stroke pneumatic control valve (B), a top rod connection sleeve, a spacing rack (b), a flat end face air cylinder, a cutter connection member, a cutter, a return stroke pneumatic control valve (C), a stroke pneumatic control valve (D), a fixing cutter, a fixing cutter seat, a manual pneumatic valve, a pedestal, an engine body and a support body. The lead core delay element end face cutting apparatus with high precision is advantageous in that a U-shaped delay element can be cut with accuracy and provides high control precision for guide explosion delay time and initiating explosive product guide explosion delay time.
