Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in seeing figures.1.and.2, a kind of miaow head pcb plate and punching press counterdie 10 structure thereof, it comprises miaow head pcb base material 20 and punching press counterdie 10, described miaow head pcb base material 20 arranges miaow head unit 21 and tailing 22, described punching press counterdie 10 is provided with the spacing hornblock of upper left benchmark 11, the spacing hornblock 12 of upper right benchmark and lower limit block 13, and the spacing hornblock of described upper left benchmark 11, the spacing hornblock 12 of upper right benchmark and lower limit block 13 wrap up and locate the edge of miaow head pcb base material 20.
As shown in Figure 2, described miaow head unit 21 is neatly regular evenly arranges in lattice-like, and described outermost miaow head unit 21 is the same with the gap of the adjacent two miaow head units 21 of Distance geometry at the edge of its immediate miaow head pcb base material 20.
As shown in Figure 1, the spacing hornblock of described upper left benchmark 11, the spacing hornblock 12 of upper right benchmark and lower limit block 13 are located at the upper left quarter of punching press counterdie 10, upper right quarter and bottom respectively.The spacing hornblock of described upper left benchmark 11 and the spacing hornblock 12 of upper right benchmark are equipped with a L shape right-angle surface 14,15, and described lower limit block 13 is at least provided with a plane 16.The middle one side of the L shape right-angle surface 14 of the spacing hornblock of described upper left benchmark 11 is parallel with the one side in the L shape right-angle surface 15 of the spacing hornblock of upper right benchmark 12, and its another side is in the same plane and parallel with a plane 16 of lower limit block 13.
As shown in figures 1-4, miaow head pcb base material 20 of the present utility model does not arrange technique narrow boards limit 41 and technique wide plate limit 42, both the material of edges of boards had been saved, improve the utilization rate of miaow head pcb base material 20, onesize pcb plate can be arranged more miaow head unit 21, same because there is no edge structure, the utility model punching press counterdie 10 is different from conventional punching press counterdie 30, without the need to arranging locating cylinder 31 and locating kidney-shaped post 32, use the spacing hornblock 11 of upper left benchmark instead, the spacing hornblock 12 of upper right benchmark and lower limit block 13 wrap up and locate the edge of miaow head pcb base material 20, this equally also can locate conventional miaow head pcb base material 40 reliably, compare steadily balanced punching press, locating circular hole 43 needed for the miaow head pcb base material 40 without the need to punching press location routine and locating mounting hole 44, originally need the technique of two times punch to be reduced to and only need punching press once, get final product straight forming final products miaow head pcb plate, stamping procedure is few, cost of stamping is low, pcb stock utilization is high, weigh wounded after avoiding and decrease a large amount of punch dies, damaged surfaces, surface abnormalities, the defects such as surface adhesion force is not enough, remarkable in economical benefits.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
