Abstract
The utility model relates to a kind of punching cutters, include the second stamping cutting die pedestal；The top two sides of the second stamping cutting die pedestal are respectively arranged with second knife edge；The section of second knife edge is at right angled triangle；The bevel edge of the right angled triangle is located at the outside of the second stamping cutting die pedestal；The top of second stamping cutting die pedestal forms the second blanking chamber between two second knifes edge；The both ends that punching cutter described in the utility model is cut the part got off since the inner wall due to the second blanking chamber does not tilt, among circuit board will not be squeezed, thus will not be deformed or flange, to guarantee the cutting quality of wiring board.
Description
Technical field
It can prevent from being cut the part extrusion or flange got off among circuit board the utility model relates to a kind of
Punching cutter.
Background technique
Attached drawing 1 is prior art punching cutter, includes the first stamping cutting die pedestal 1；The first stamping cutting die pedestal 1
Top two sides are respectively arranged with first knife edge 2；The section of first knife edge 2 is at isosceles triangle；First stamping cutting die pedestal 1
Top, form the first blanking chamber 3 between two first knifes edge 2.
When work, as shown in Fig. 2, the bottom in the first blanking chamber 3 is placed with foam (not shown), and circuit board 4 is by
One knife edge 2 is cut off, and being cut the part got off among circuit board 4 can fall into the first blanking chamber 3, is cut among circuit board 4
The part got off can then be rebounded out by foam, and the part got off is cut among circuit board 4 can fall into the first blanking chamber 3
During rebounding out, since the inner wall of the first blanking chamber 3 tilts, and spacing is gradually reduced, under being cut among circuit board 4
The both ends for the part come can be deformed because of squeezing or flange, thus influence the cutting quality of wiring board 4.
For this purpose, we have developed and a kind of can prevent from being cut the part extrusion or flange got off among circuit board
Punching cutter.
Utility model content
The utility model aim is for overcome the deficiencies in the prior art and providing a kind of can prevent from being cut out among circuit board
The punching cutter of the part extrusion or flange that scale off.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of punching cutter, includes the second punching press knife
Mold base；The top two sides of the second stamping cutting die pedestal are respectively arranged with second knife edge；The section of second knife edge at
Right angled triangle；The bevel edge of the right angled triangle is located at the outside of the second stamping cutting die pedestal；Second stamping cutting die base
The top of seat forms the second blanking chamber between two second knifes edge.
Preferably, second knife edge is arranged in parallel.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
Punching cutter described in the utility model is cut out among circuit board since the inner wall due to the second blanking chamber does not tilt
The both ends of the part scaled off will not be squeezed, thus will not be deformed or flange, to guarantee cutting for wiring board
Quality.
Detailed description of the invention
Technical solutions of the utility model are described further with reference to the accompanying drawing:
Attached drawing 1 is the schematic diagram of punching cutter in the prior art；
Attached drawing 2 is the application state schematic diagram of punching cutter in the prior art；
Attached drawing 3 is the schematic diagram of punching cutter described in the utility model；
Attached drawing 4 is the application state schematic diagram of punching cutter described in the utility model；
Wherein: 1, the first stamping cutting die pedestal；2, first knife edge；3, the first blanking chamber；4, circuit board；11, the second punching press
Cutting die pedestal；12, second knife edge；13, the second blanking chamber.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Attached drawing 3 is punching cutter described in the utility model, includes the second stamping cutting die pedestal 11；The second punching press knife
The top two sides of mold base 11 are respectively arranged with second knife edge 12；The section of second knife edge 2 is at right angled triangle；It is described straight
Angle hypotenuse is located at the outside of the second stamping cutting die pedestal 11；The top of second stamping cutting die pedestal 11, two
The second blanking chamber 13 is formed between two knifes edge 12.
Second knife edge 12 is arranged in parallel.
When work, as shown in Fig. 4, the bottom in the second blanking chamber 13 is placed with foam (not shown), and circuit board 4 is by
Two knifes edge 12 are cut off, and being cut the part got off among circuit board 4 can fall into the second blanking chamber 13, are cut out among circuit board 4
The part scaled off can then be rebounded out by foam, and the part got off is cut among circuit board 4 can fall into the second blanking chamber
To during rebounding out in 13, since the inner wall of the second blanking chamber 13 does not tilt, the part got off is cut among circuit board 4
Both ends will not be squeezed, thus will not deform or flange, to guarantee the cutting quality of wiring board 4.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
Punching cutter described in the utility model is cut out among circuit board since the inner wall due to the second blanking chamber does not tilt
The both ends of the part scaled off will not be squeezed, thus will not be deformed or flange, to guarantee cutting for wiring board
Quality.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
