Punching machine capable of achieving automatic reciprocating material receiving

The invention relates to a punching machine capable of achieving automatic reciprocating material receiving. The punching machine comprises a rack. A bottom plate is arranged on the rack. A bent beam is arranged at one end of the bottom plate. A pressure cylinder is arranged on the bent beam and provided with a punching connector to be connected with an upper die fixing seat. The upper die fixing seat is provided with an upper die pressing plate to be connected with an upper die. The bottom plate is provided with a sliding seat. The sliding seat is provided with a first sliding groove. The first sliding groove is provided with a sliding plate. One end of the sliding plate is provided with an air cylinder connector to be connected with a feeding air cylinder. The upper end of the sliding plate is provided with a baffle pressing block to fix a lower die. A front check block and a rear check block are arranged on the baffle pressing block, abut against inclined faces on the two sides of the lower die respectively and are partially higher than the lower die, and thus a channel is formed. A copper electrode and a feeding mechanism are correspondingly arranged on the two sides of the rear check block respectively, and the copper electrode is provided with a copper electrode seat so as to be fixed to the sliding seat. The punching machine capable of achieving automatic reciprocating material receiving is simple in structure, safe and convenient to operate and capable of greatly improving the original working efficiency.
