Fig. 2 is the utility model punch structure schematic diagram.
Fig. 3 is the utility model die block structural representation.
Wherein: 1. upper bolster; 2. punch retainer; 3. punch; 31. locator protrusions; 4. die shoe; 5. fixed block; 6. die block; 7. die mold insert; 8. guidance set; 10. light fixture cover.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1-Figure 3, the utility model provides a kind of cantilever punching die, comprises upper die and lower die, guidance set, to be led punching press, it is characterized in that between patrix and counterdie by guidance set:
Described patrix comprises upper bolster 1, punch retainer 2 and punch 3, and described punch 3 is fixed by locator protrusions 31 with punch retainer 2, save raw material, the cutting edge 32 of described punch 3 is V-shape, and comparatively cutting edge 32 part is thick for the fixed part 33 of described punch 3, adds the intensity of punch 3.
Described counterdie comprises die shoe 4, fixed block 5, die block 6, described die shoe 4 is bolted with fixed block 5, described fixed block 5 side is vertical with die block 6 to be connected and fixed, described die block 6 is provided with die mold insert 7, described die mold insert 7 is removable, described die block 6 and die mold insert 7 are provided with punching mouth 71, and die block 6 coordinates with light fixture cover 10 abnormity.
Preferably, the sample introduction side 61 of described die block 6 is provided with lead angle, and the number of degrees of lead angle are 5 °, facilitates light fixture cover 10 to insert in die block 6.
Preferably, be provided with waste material mouth 72 below described punching mouth 71, waste material mouth 72 diameter is greater than punching mouth 71, jumps material after preventing die-cut completing.
Preferably, the angle of the cutting edge 32V font of described punch 3 is 90 °-120 °, reduces the cracking of punch process medium section, can effectively avoid jumping material simultaneously.
The beneficial effects of the utility model are: the punching processing facilitating closed work piece, improve the accuracy of punching, add die mold insert, after die is out of shape service time for a long time, directly changes die mold insert, reduce production cost.
