Abstract
The utility model discloses a kind of deburring knife edge structure, including the insert of upper mould first, the insert of upper mould second, and lower mould waste knife, it is characterised in that：A wedge angle position is set at the cutting edge that first insert is engaged with lower mould waste knife.The generation of iron filings is this construction reduce, the surface quality for producing iron filings influence outer covering piece in outer covering piece production process at deburring waste knife is solved, is suitable for various outer covering piece moulds；The structure design is simple, cost is low, effectively save die procedure, saves die cost and production cost.
Description
Technical field
Trimming Die technical field is the utility model is related to, especially a kind of deburring knife edge structure.
Background technology
In automobile exterior panel part diel, iron filings caused by trimming process step can influence exterior panel surface quality of workpieces.Especially
It is waste material cutter position, and the structure of waste knife, which causes, easily produces iron filings.For such situation, to the upper of waste material cutter position
Mould cutter block has carried out structure improvement, reduces the generation of burr.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of deburring edge of a knife knot
Structure, reduce the generation of iron filings, solve the problems, such as that deburring falls iron filings and influences product surface quality.
The utility model solves technical scheme used by prior art problem：A kind of deburring knife edge structure, including upper mould
First insert, the insert of upper mould second, and lower mould waste knife, it is characterised in that：First insert matches with lower mould waste knife
A wedge angle position is set at the cutting edge of conjunction.
Described wedge angle position angle is 60o。
Described wedge angle position is highly 5mm.
Described corners bit width is 8mm.
Above-mentioned technical proposal is employed, the utility model has following beneficial effect：It this construction reduce the production of iron filings
It is raw, solve the surface quality for producing iron filings influence outer covering piece in outer covering piece production process at deburring waste knife, be suitable for
Various outer covering piece moulds；The structure design is simple, cost is low, effectively save die procedure, saves die cost and is produced into
This.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the first insert structure schematic diagram of the present utility model.
Fig. 3 is the first insert structure type face of the present utility model schematic diagram.
Embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
A kind of deburring knife edge structure as shown in Figure 1 to Figure 3, including the first insert of upper mould 1, the second insert of upper mould 2, and
Lower mould waste knife 3, a wedge angle position 4, wedge angle position 4 are set at the cutting edge that upper the first insert of mould 1 is engaged with lower mould waste knife 3
Angle a is 60o, height h is 5mm, and width w is 8mm.
During work, upper the first insert of mould 1, the second insert of upper mould 2, and lower mould waste knife 3 constitute the waste knife of deburring
Structure, waste material is punctured by the pointed part 4 of upper the first insert of mould 1 and then be broken again when cutting off waste material, so produced
Iron filings it is fewer than the structure directly cut, when exterior panel produces, reduce the generation of iron filings, solve outer covering piece and produced
Producing iron filings in journey at deburring waste knife influences the surface quality of outer covering piece.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
