Abstract
The invention discloses a split type bracket punching die. The split type bracket punching die comprises an upper die plate, a lower die plate, a die, a punch assembly and a positioning block, wherein the upper die plate is positioned above the lower die plate; the die is arranged on the lower die plate; the punch assembly is arranged below the lower die plate; through grooves allowing the punch assembly to pass are formed in the lower die plate and the die; the punch assembly comprises a punch and a boss; the cross section of the punch is in the shape of an isosceles trapezoid; the included angle of the two waists of the isosceles trapezoid is 90 degrees; the boss is arranged on the outer side surface of the punch; the bottom surface of the boss is positioned below the bottom surface of the punch; the outer side surface of the boss is flush with the outer side walls of the through grooves; the positioning block is arranged on the die. According to the split type bracket punching die, the upper die plate is fixed with a punching nose, the lower die plate is arranged on a fixed disc of a punch press, when the punching nose moves downwards, the punch is pushed to perform punching on a steel angle, the punching precision is high, and the punching quality is improved.
Description
Technical field
The present invention relates to a kind of die cutting die, particularly a kind of support die cutting die used in making stent procedures.
Background technology
When making support as described in Figure 1, comprise the processing step that a following step is die-cut, namely on the angle steel 8 shown in accompanying drawing 2, the breach 9 of die-cut 2 isosceles trapezoid shape.In order to make clicking technique quick, carrying out accurately, needing to use die cutting die.Diel is in the past simpler and easy, but die-cut accuracy is not high, and the quality of die-cut technique directly affects the carrying out of lower step process, therefore designs a kind of die-cut accurate die cutting die imperative.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the separating stent-graft die cutting die that a kind of die cutting accuracy is high.
Technical solution of the present invention is achieved in that a kind of separating stent-graft die cutting die, comprises cope match-plate pattern, lower bolster, die, punch assemblies and locating piece; Described cope match-plate pattern is positioned at the top of lower bolster; Described lower bolster is provided with die; The below of described cope match-plate pattern is provided with punch assemblies; Described lower bolster and die have the groove that punch assemblies is passed through; Described punch assemblies comprises punch and boss; The cross section of described punch is isosceles trapezoid; Two waist angles of described isosceles trapezoid are 90 °; Described boss be arranged on punch lateral surface; The bottom surface of described boss is positioned at the below of punch bottom surface; The lateral surface of described boss is mutually concordant with the lateral wall of groove; Described die is provided with locating piece.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Separating stent-graft die cutting die of the present invention, cope match-plate pattern and punching machine head fix, and described lower bolster is arranged on the fixed disk of stamping machine, and punching machine head descending promotion punch carries out die-cut to angle steel.Support die cutting die of the present invention, guiding and location all rely on boss, and the lateral surface of boss is mutually concordant with the lateral wall of groove, subjects the side force in blanking process, die cutting accuracy is guaranteed, improves stamping quality.

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram needing the support made;
Accompanying drawing 2 is the structural representation needing die-cut angle steel;
Accompanying drawing 3 is the structural representation of separating stent-graft die cutting die of the present invention;
Accompanying drawing 4 is the A-A cross-sectional view of accompanying drawing 3;
Accompanying drawing 5 is separating stent-graft die cutting die using state structural scheme of mechanism of the present invention;
Wherein: 1, cope match-plate pattern; 2, lower bolster; 3, die; 4, locating piece; 5, groove; 6, punch; 7, boss; 8, angle steel; 9, breach.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of separating stent-graft die cutting die as shown in accompanying drawing 3,4, comprises cope match-plate pattern 1, lower bolster 2, die 3, punch assemblies and locating piece 4; Described cope match-plate pattern 1 is positioned at the top of lower bolster 2; Described lower bolster 2 is provided with die 3; The below of described cope match-plate pattern 2 is provided with punch assemblies; Described lower bolster 2 and die 3 have the groove 5 that punch assemblies is passed through; Described punch assemblies comprises punch 6 and boss 7; The cross section of described punch 6 is isosceles trapezoid; Two waist angles of described isosceles trapezoid are 90 °; Described boss 7 be arranged on punch 6 lateral surface; The bottom surface of described boss 7 is positioned at the below of punch 6 bottom surface; The lateral surface of described boss 7 is mutually concordant with the lateral wall of groove 5; Described die 6 is provided with locating piece 4.
Separating stent-graft die cutting die of the present invention as shown in Figure 5, cope match-plate pattern 1 and punching machine head fix, described lower bolster 2 is arranged on the fixed disk of stamping machine, during use, die-cut face is needed by angle steel 8 to be placed on die 3, another side is then near locating piece 4, the staking punch of stamping machine is descending, drive cope match-plate pattern 1 descending, thus drive punch assemblies descending, the lateral surface of boss 7 is mutually concordant with the lateral wall of groove 5, boss 7 plays the effect of guiding and location, subject the side force in blanking process simultaneously, the die-cut angle steel 8 of punch 6, punch out breach, waste material then spills from groove 5, after one-step punching terminates, the staking punch of stamping machine is up, and after cope match-plate pattern 1 is driven initial position, it is die-cut to carry out next time.
Support die cutting die of the present invention, die cutting accuracy is high, improves stamping quality.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
