Smooth, volume production stability is not high.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of 3D cutting cutter die, the knife cut is needed in product
Road when on the face 3D, also can coplanar cutting cutter die equally product is cut using pressing machine or punching machine, cut rear notch
Smooth no soft flocks, precision original text, cutting edge roundness angle is reasonable, and cutter life and sharpness is made to reach balance.
A kind of 3D cutting cutter die, it includes lower mold, upper mold；Lower mode is inlaid on the lower mold；Described
Upper mold is equipped with workpiece holding tank；The lower mode upper surface is 3D curved surface, and the cutting that lower mode upper surface is equipped with
Knife；Plane where at the top of the blade of the shearing knife is 3D curved surface；
Further, the shearing knife is in closed hoop 3D curve-like；Section is in triangular shape；Including the first knife face and
Two knife faces；
Further, the first knife face of shearing knife is vertically arranged, and the inner or outer side of the first knife face is arranged in the second knife face；
Further, the shearing knife is in open 3D curve-like；Section is in triangular shape；Including the first knife face and the second knife
Face；First knife face is vertically arranged, and the side of the first knife face is arranged in the second knife face；
Further, the junction of first knife face and the second knife face is equipped with chamfering；
Further, second knife face is arc surface；
Further, the setting of shearing knife protrusion is on lower mode upper surface；
The utility model provides a kind of 3D cutting cutter die, it includes lower mold, upper mold；It is inlayed on the lower mold
There is lower mode；The upper mold is equipped with workpiece holding tank；The lower mode upper surface is 3D curved surface, and table on lower mode
The shearing knife that face is equipped with；Plane where at the top of the blade of the shearing knife is 3D curved surface；The shearing knife is in close ring
Shape 3D curve-like；Section is in triangular shape；First knife face is vertically arranged, and the inner or outer side of the first knife face is arranged in the second knife face；
The junction of first knife face and the second knife face is equipped with chamfering；Second knife face is arc surface；The shearing knife
The setting of protrusion is on lower mode upper surface；The utility model can add when in use according to different being customized of workpiece
Work, to guarantee the precision of shearing；Shearing knife section is in triangular shape, and the junction of the first knife face and the second knife face is equipped with chamfering,
The sharpness of the cutting edge of entire shearing knife and cutter life is set to reach balance；Chamfering makes the cutting edge of shearing knife will not be straight when shearing
It connects and is touched with the side edge of the groove on the inside of workpiece；But be in contact first with skin rim charge, the first knife face being vertically arranged again with
The side edge of groove on the inside of workpiece is touched；The case where avoiding the cutting edge defective work piece of shearing knife generation.

Specific embodiment
Embodiment：
Attached drawing 1-4 is referred to, a kind of 3D cutting cutter die, it includes lower mold 1, upper mold 2；
Lower mode 11 is inlaid on the lower mold 1；
The upper mold 2 is equipped with workpiece holding tank 21；
Workpiece 3 is equipped in the workpiece holding tank 21；
The workpiece 3 is arc-shaped, and surface is coated with musculus cutaneus 31, and groove 32 is equipped on the inside of workpiece 3, is equipped with inside groove 32
Musculus cutaneus rim charge 33；
11 upper surface of lower mode is 3D curved surface, identical as the underside shape of workpiece 3；
The shearing knife 12 that 11 upper surface of lower mode is equipped with；
The setting that the shearing knife 12 is protruded is on lower 11 upper surface of mode；Plane where at the top of the blade of shearing knife 12
For 3D curved surface, and match with the edge shape of the groove of workpiece 3 32；
The shearing knife 12 is in closed hoop 3D curve-like, and section is in triangular shape；
