Description
Technical field
The present invention relates to punching die field, in particular to a kind of sphere cantilever type bidirectional punching die.
Background technology
Perforating die is the punch die that a kind of profile that edge is closed on blank or sheet material isolates that waste material obtains being with orifice.To when sphere carries out punching processing with the product in relative hole, because sphere is curved surface, be very easy to during punching make workpiece produce distortion, the product crudy finally obtained is difficult to ensure.Existing technology is generally utilize unidirectional perforating die to carry out punching singly, although workpiece does not produce distortion when this method can ensure punching preferably, but working (machining) efficiency is lower, need to carry out twice clamping, twice punch operation, and the axiality in go out two holes is difficult to ensure, parts quality is still not ideal enough.
Summary of the invention
The invention provides a kind of sphere cantilever type bidirectional punching die, be intended to improve the problems referred to above.
The present invention is achieved in that
A kind of sphere cantilever type bidirectional punching die, comprise die shoe and upper bolster, described die shoe is provided with cantilever portion, one end of described cantilever portion is connected with described die shoe by die holder, the other end of described cantilever portion is working end, described working end is provided with spherical, described spherical is relatively provided with upper cavity die and lower cavity die up and down, described upper bolster is provided with upper male mould, described die shoe is provided with lower punch, described upper male mould is corresponding with described upper cavity die, described lower punch is corresponding with described lower cavity die, described die shoe is respectively arranged with fixture block in the position of the left and right sides near described working end, described fixture block and described die shoe removably connect.
Further, described fixture block comprises clamping section and two holding parts, two described holding parts are connected with the two ends up and down of described clamping section respectively, described clamping section is provided with the arcwall face of indent, arcwall face on the clamping section of two fixture blocks is oppositely arranged, described holding part is provided with the holding face of arc, the holding face on the holding part of each fixture block is arranged all in opposite directions.
When mounting spherical workpiece, spherical workpiece is covered in the working end of cantilever portion, then respectively two fixture blocks are installed, the arcwall face on the clamping section of two fixture blocks is made to be stuck in spherical workpiece, because arcwall face is arc, all fastening effect can be played to sphere in all directions, therefore the design of fixture block takes full advantage of the features of shape of spherical workpiece itself, the effect of clamping spherical workpiece can be played well, and auxiliary fixing effect now can be played in the holding face of holding part, both match and make spherical workpiece clamping more firm.In addition, holding part with the holding face of arc in punch process, holding power can be provided to spherical workpiece, namely the holding part being positioned at top provides the holding preventing spherical workpiece from moving up power, the holding part being positioned at below provides the holding preventing spherical workpiece from moving down power, when making bidirectional punching, spherical workpiece is more firm, thus prevent spherical workpiece from producing larger distortion when punching, ensure that the quality of product.
Further, described die shoe is provided with ring-shaped groove in the position near described fixture block.By arranging ring-shaped groove, the spacing effect of clamping can be played to the edge of spherical workpiece, making spherical workpiece fixing more firm, being particularly suitable for the spherical workpiece being processed with flange.
Further, the upper end of described cantilever portion is provided with punch guide plate, described punch guide plate is provided with the through hole passed through for described upper male mould.
By punch guide plate, guide effect can be played when upper male mould moves downward and carries out punching, prevent the motion of upper male mould from producing skew and causing punching crooked, affect the precision of punching and the quality of product.
Further, described punch guide plate is provided with alignment pin, described upper bolster is provided with the pin-and-hole corresponding with described alignment pin.
By arranging alignment pin on punch guide plate, the effect of location can be played to the motion of upper bolster, thus ensure that the motion of upper male mould is accurate.
Further, the below of described cantilever portion is provided with stop, and described stop is sheathed on outside described die holder.
Stop can play to cantilever portion the effect supporting restriction.On the one hand, because cantilever portion is outwardly directed cantilever, in punch process, may produce larger moment of flexure under the effect of impulsive force to cantilever portion, Long-Time Service then can cause cantilever portion to bend, thus affects machining accuracy, and even normal punching uses.The setting of stop can play the effect of support, substantially reduces moment of flexure suffered by cantilever portion.On the other hand, in punch process, stop also can play the effect of moving-limiting to cantilever portion, make the position of cantilever portion fixed, prevents distortion.
