For realizing that the technical scheme that purpose of the present invention adopts is: a kind of punching production method with V-arrangement rib steel expanded metals, adopt many row's drifts that steel plate is carried out punching press, the step pitch of sending to of its friction feeding equals the otch spacing that drift is arranged the V-arrangement rib steel expanded metals of several times, i.e. L=NS;
Described drift is equidistant evenly distributed, and the distance of arranging of its adjacent two row's drifts meets following formula:
H≠nNS，
When N can be decomposed into two factors, promptly work as N=X
1* X
2The time,
Also need satisfy H ≠ nX simultaneously
1S and H ≠ nX
2S,
Wherein, the distance of arranging between the adjacent two row's drifts of H-;
Row's number of N-drift;
The otch spacing of S--V shape rib steel expanded metals;
N--- natural number 1,2,3,4,5 ...
In the condition that allow the locus of drift, the distance H value preferred minimum value between adjacent two row's drifts is beneficial to save the space.
