The invention belongs to the technical field of manufacturing devices for initiating explosive devices, and particularly relates to a high-precision flat cutting device for the end surfaces of delay elements with lead cores. By the aid of the high-precision flat cutting device, the technical problem of low detonating delay time control precision of initiating explosive devices due to the difficulty in controlling the detonating delay time of existing delay elements with lead cores mainly can be solved. The high-precision flat cutting device for the end surfaces of the delay elements with the lead cores comprises an ejector cylinder, a mounting frame, a limiting support a, a return pneumatic control valve A, a set-out pneumatic control valve B, an ejector rod connecting sleeve, an ejector rod, a limiting support b, a flat end surface cylinder, a cutter connecting piece, a cutter, a return pneumatic control valve C, a set-out pneumatic control valve D, a fixed cutter, a fixed cutter holder, a manual pneumatic control valve, a base, a machine and a supporting body. The high-precision flat cutting device has the advantages that the 'horseshoe' delay elements can be accurately and effectively flatly cut by the high-precision flat cutting device, the detonating delay time is easy to control, and initiating explosive devices are high in detonating delay time control precision.
Description
technical field [0001] The invention belongs to the technical field of pyrotechnic product manufacturing devices, and in particular relates to a high-precision lead core extension body end face cutting and flattening device. Background technique [0002] Delay piece is a kind of pyrotechnic device that uses the burning speed of the agent to control the ignition time, such as time medicine plate, delay powder column and safety powder column, etc. Lead core delay piece is one of them. Existing lead extension piece, its shape is that one side is smooth and flat, and the other side then becomes inclined-plane, is called " horseshoe shape " in the industry. Since the detonation delay time of the slope is not easy to control, the control accuracy of the detonation delay time of the pyrotechnic product is low, which brings potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the detonation delay ...
