Abstract
A combined cutter die comprises a base, a cutter board, a cutter point and a cover plate; the cutter board is fixed on the base; the cutter point is fixed on the upper surface of the cutter board; the cover plate moves up and down along with a punch press upper die; at least three positioning pins are detachably embedded on the cutter board; the centers of the positioning pins are at the same straight line and are parallel with the cutter point; the height of the cutter point is larger than the thickness of a strip-shaped auxiliary material, the heights, exposed out of the cutter board, of the positioning pins are higher than the height of the cutter point. The combined cutter die has the beneficial effects that 1, two edges of the strip-shaped auxiliary material are parallel and the machining precision is improved; 2, one set of die can adapt to the machining of the strip-shaped auxiliary materials of different standards, and the die cost is saved.
Description
Technical field
The utility model relates to a kind of cutting dies for the auxiliary material of wiring board strip, particularly a kind of combination cutting die that can be used in the auxiliary material cutting of plurality of specifications wiring board strip.
Background technology
In designed lines plate process, often need to make sample, make the auxiliary material of strip that sample wiring board just need to first be made dimension.Because the length of the auxiliary material of strip is several conventional standard specifications, difference is width, the making of sample be the trial-production of the small lot width specifications that may relate to from 2mm to 20mm all likely, before often using a kind of specification, all need newly to open a mold, in the situation that required precision is not high, just with cutting machine, complete.But it is higher for this small quantities of trial-manufacture of sample, to make a set of die cost, and the utilization rate of this trial-production mould is very low, causes the waste of cost; If use cutting machine sawing sheet, precision is inadequate, and error is more than 0.2mm.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of combination cutting die that can be used in the auxiliary material cutting of plurality of specifications wiring board strip.
Technical scheme: a kind of combination cutting die, comprise base, knife plate, the knife edge and cover plate, described knife plate is fixed on base, the knife edge is fixed on the upper surface of knife plate, cover plate moves up and down with upper die of punching press, detachablely on described knife plate is inlaid with at least three alignment pins, and the center of described alignment pin is on same straight line and parallel with the knife edge, the height of the described knife edge is greater than the thickness of the auxiliary material of bar shaped, and described alignment pin exposes the part of knife plate higher than the height of the knife edge.The auxiliary material of bar shaped is fixed between the knife edge and cover plate by the locating hole on it, and cover plate moves downward the cutting realizing the auxiliary material of bar shaped.
Beneficial effect: 1, guaranteed that two limits of the auxiliary material of bar shaped are parallel, improved machining accuracy; 2, the processing that a mold can the auxiliary material of suitable for various size bar shaped, has saved die cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view that the utility model is removed cover plate;
Fig. 3 is the schematic diagram one of the auxiliary material of the utility model cutting bar shaped;
Fig. 4 is the schematic diagram two of the auxiliary material of the utility model cutting bar shaped.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As illustrated in fig. 1 and 2, a kind of combination cutting die, comprise base 1, knife plate 2, the knife edge 3 and cover plate 4, described knife plate 2 is fixed on base 1, and the knife edge 3 is fixed on the upper surface of knife plate 2, and cover plate 4 moves up and down with upper die of punching press, detachablely on described knife plate 2 be inlaid with seven alignment pins 5, the center of described alignment pin 5 is on same straight line and parallel with the knife edge 3, and the height of the described knife edge 3 is greater than the thickness of the auxiliary material 6 of bar shaped, and described alignment pin 5 exposes the part of knife plate 2 higher than the height of the knife edge 3.
As shown in Figure 3, first on first group of locating hole of the auxiliary material 6 of bar shaped 7 being fixed between the knife edge 3 and cover plate 4 through the alignment pin 5 on knife plate 2, cover plate 4, along with patrix moves downward the hole back gauge that the unnecessary part in the excision auxiliary material of bar shaped 6 ends forms standard, is realized the finishing to the auxiliary material 6 of former bar shaped simultaneously.
As shown in Figure 4, second group of locating hole of the auxiliary material 6 of trimmed bar shaped 7 is fixed between the knife edge 3 and cover plate 4 and gone up through the alignment pin 5 on knife plate 2,, cover plate 4 moves downward the auxiliary material 6 of bar shaped that cuts out required size again.The centre-to-centre spacing of two groups of locating holes 7 is exactly the width of the auxiliary material 6 of required bar shaped, and the span between same group of locating hole 7 is can be combined in order to adapt to the auxiliary material 6 of bar shaped of different size.
