Description
[technical field]
The utility model relates to a kind of mould, is specifically related to a kind of blanking die.
[background technology]
The structure of existing blanking die is: comprise up and down mould bases, left and right sides guide pillar, punch and die, left and right sides guide pillar is fixedly installed at lower mold holder, top mold frame is actively installed on the guide pillar of the left and right sides by guide pin bushing, punch is in the fixed installation of the bottom surface of top mold frame, die is in the end face fixed installation of lower mold holder, left and right sides guide pillar has identical external diameter, and chamber, the end direct and die, the edge of a knife below of die borders on.Its shortcoming is: punch, die need irregularly be changed after wearing and tearing, blanking die behind replacing punch or the die need to carry out mould, because the external diameter of left and right sides guide pillar is identical, two dowel hole internal diameters of top mold frame are also identical, if so do not carry out in advance mark, be easy to top mold frame is put back, top mold frame just needs the transposing direction again to gain installation like this, cause the mould inconvenience, inefficiency labour intensity is large; Also have, because chamber, the end direct and die, the edge of a knife of die below borders on, the knife edge thickness of die is thin, so the edge of a knife damages easily, affects the service life of blanking die.
[summary of the invention]
The utility model provides a kind of blanking die convenient to mould, the long service life advantage that has.
The utility model takes following technical scheme to finish:
A kind of to mould blanking die easily, comprise up and down mould bases, left and right sides guide pillar, punch and die, left and right sides guide pillar is fixedly installed at lower mold holder, top mold frame is actively installed on the guide pillar of the left and right sides by guide pin bushing, punch is in the fixed installation of the bottom surface of top mold frame, die is in the end face fixed installation of lower mold holder, and it is characterized in that: described left and right sides guide pillar has different external diameters.The edge of a knife below of described die is by the end chamber of one section chamfered transition to die.
The blanking die of technique scheme, because left and right sides guide pillar has different external diameters, so two dowel holes of top mold frame also have different internal diameters certainly, so just only have a unique correspondence position between top mold frame and the lower mold holder, the phenomenon that top mold frame is put back can never appear, blanking die convenient to mould.In addition, the edge of a knife of described die below is equivalent to the reinforcement of die edge of a knife intensity by the chamber, the end of one section chamfered transition to die, and the edge of a knife is not easy to damage, thereby has increased the service life of blanking die.
[description of drawings]
The utility model has the following drawings:
Fig. 1 is structural representation of the present utility model.
[specific embodiment]
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the operation principle thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, blanking die of the present utility model, comprise top mold frame 1, lower mold holder 2, left guide pillar 5, right guide pillar 3, punch 7 and die 8, left and right sides guide pillar is fixedly installed at lower mold holder 2, left and right sides guide pillar has different external diameters, left guide pillar 5 is thin, right guide pillar 3 is thick, top mold frame 1 is actively installed on the guide pillar of the left and right sides by guide pin bushing 6 and guide pin bushing 4, guide pin bushing 6 apertures are little, and guide pin bushing 4 apertures are large, and punch 7 is in the fixed installation of the bottom surface of top mold frame 1, die 8 is in the end face fixed installation of lower mold holder 2, and the edge of a knife 9 belows of described die are transitioned into the chamber, the end 11 of die by one section inclined-plane 10.
The blanking die of technique scheme because left and right sides guide pillar has different external diameters, the phenomenon that top mold frame is put back can not occur, blanking die convenient to mould; The intensity of the die edge of a knife is strengthened simultaneously, and the edge of a knife is not easy to damage, and has increased service life.
