when the die assembly punching is carried out, the material pressing column (61) is slowly contacted with the lower die holder (20) and moves upwards under the compression action of the spring (62) to be fully assembled, and finally the material pressing column is pressed on the flat wire of the lower die holder (20) due to the reaction force of the compression of the spring (62).
8. The flat wire forming and stamping die according to claim 7, further comprising a manual pressing assembly (70) located at the material passing space (30) and fixed above the rail seat (51).
9. The flat wire forming and stamping die of claim 6, wherein: the afterbody of die holder (20) still is provided with spacing subassembly (80), spacing subassembly (80) include:
the limiting strip (81) is arranged at the bottom of the lower die holder (20) and can reciprocate along the feeding direction; a positioning through groove (81a) arranged along the feeding direction is formed in the limiting strip (81), and a scale value is further arranged on the outer side of the positioning through groove (81 a);
the limiting rod (82) is vertically arranged at the tail end of the limiting strip (81), and the flat wire penetrates in the feeding direction of the material passing space (30) until the end part of the flat wire abuts against the limiting rod (82);
and the adjusting pin (83) penetrates through the positioning through groove (81a), and the distance between the limiting rod (82) and the lower die seat (20) is adjusted by rotating the adjusting pin (83) and moving the limiting strip (81).
10. A stamping apparatus, characterized in that: a flat wire forming and stamping die as claimed in any one of claims 1 to 9.
