Detailed description of the invention
In order to better understand the utility model relative to the improvement done by prior art, before three kinds of specific embodiments of the present utility model are described in detail, first the prior art that background technology part is mentioned is illustrated by reference to the accompanying drawings:
Fig. 1 shows the syndeton of magneto core blanking die in prior art, and convex mould pad 4 is all fixedly connected with die holder 1 by bolt with punch retainer 10, and is located by alignment pin.Blanking punch 7 upper end is integrally formed with the boss for locating, and blanking punch 7 is between punch retainer 10 and convex mould pad 4.In use, only have the stamping-out that the ledge of blanking punch 7 could be used for sheet material, the part that boss and blanking punch 7 overlap with punch retainer 10 cannot use, and this can cause mould to have major part waste.Meanwhile, the own vol of boss and working (finishing) area are all comparatively large, when not only causing mould to produce, use material more, also improve cost and the process time of mould production and processing.
As shown in Figure 2, the magneto core blanking die syndeton of the first embodiment of the utility model, convex mould pad 4 has the fixing hole 3 for fixing blanking punch 7, and convex mould pad 4 is connected with the lower bolt 2 of upper bolster 1.Blanking punch 7 is strip structure, and the geometric center of its lower end has coaxially and the via hole 6 communicated and connecting hole 5 successively, and the diameter of connecting hole 5 is identical with fixing hole 3, and the diameter of via hole 6 is greater than the diameter of connecting hole 5.Bolt 2 is threaded with fixing hole 3 through via hole 6 and connecting hole 5 successively.Like this, blanking punch 7 is directly fixed on convex mould pad 4, and does not need punch retainer 10 to be fixed, and saves material; And due to blanking punch 7 be strip structure, blanking punch 7 directly can pass holding pad and punch retainer 10, blanking punch 7 could be changed after no longer needing holding pad and punch retainer 10 to dismantle, be convenient to blanking punch 7 and install and change, increase work efficiency.Bolt 2 is arranged with spring shim (not shown), spring shim, between bolt 2 and blanking punch 7, can prevent the impact shock because producing during mold work from bolt 2 is come off gradually.
