Abstract
The utility model discloses one kind being used for the small angle bending progressive die of hardware terminal, including upper die and lower die, material strip is equipped between the upper die and lower die, the material strip is equipped with several stations, the station includes pre- trimming station, trimming station and bending station, the bending station includes the small angle bending station arranged successively, preceding 45 degree of bending stations, 70 degree of bending stations and rear 45 degree of bending stations, the low-angle bending station is arranged between the pre- trimming station and trimming station, and preceding 45 degree of bending stations are arranged in after the trimming station.It passes through the pre- trimming station that is arranged on material strip, first the portion profile of bending is needed to cut out at small angle, small angle is subjected to bending again, then remaining waste material is cut out by trimming station, the binder area for increasing small angle bending keeps bending angle and bending length more stable when carrying out bending again with sufficiently large pressure-plate-force, the intensity of material strip is also improved simultaneously, and feeding is more smooth.
Description
Technical field
The utility model is related to field of machining, and in particular to one kind being used for the small angle bending progressive die of hardware terminal.
Background technology
Currently, many hardware terminals are all first by such production of punching press again after electroplating material tin since tiny intensity is weak on inductance
The fast quality requirements of rate request are stable when the very big requirement of product market demand produces and have to material-saving.In the prior art, it is
First by the waste material complete resection around small angle, then tearing notch divides small angle to 4 bendings in place again again.Since the product is will first to expect
Stamping material cannot be suppressed with the binder part after electrotinning again on the former mold of punching press otherwise can break can tin layers cause
Product is bad.The small angle bending binder surface and very little only 0.6X1.0mm of the product.Lead to be easy pressure-plate-force in bending process not
So that bending angle is unstable and bending length shakiness situation occurs causing prodigious quality hidden danger enough.
Utility model content
The utility model provides one kind and being used for the small angle bending progressive die of hardware terminal, and which overcome exist in background technology
The technical issues of.
Technical solution adopted by the utility model to solve its technical problems is：
One kind being used for the small angle bending progressive die of hardware terminal, including upper die and lower die, is equipped between the upper die and lower die
Material strip, the material strip are equipped with several stations, and the station includes pre- trimming station, trimming station and bending station, described
Bending station include be followed successively by tandem arrangement small angle bending station, preceding 45 degree of bending stations, 70 degree of bending stations and after
45 degree of bending stations, the low-angle bending station are arranged between the pre- trimming station and trimming station, described first 45 degree
Bending station is arranged in after the trimming station.
In one embodiment：The small angle bending station includes four distribution bending stations.
In one embodiment：Further include cutting waste station, it is described cut waste station arrangement in the rear 45 degree of bending stations it
Afterwards.
In one embodiment：The pre- trimming station includes the cavity plate for going out small angle bending part.
In one embodiment：Further include tearing notch station, the tearing notch station is arranged in after the pre- trimming station.
Compared with the prior art, it has the following advantages that：
Small angle bending progressive die provided by the utility model, it, first will be small by the pre- trimming station being arranged on material strip
Angle needs the portion profile of bending to cut out, then small angle is carried out bending by tearing notch in four times, remaining waste material is then passed through trimming
Station is cut out, and increases the binder area of small angle bending, is had when 45 degree of bendings, 70 degree of bendings and rear 45 degree of bendings before progress
Sufficiently large pressure-plate-force so that bending angle and bending length become more stable, while the intensity of material strip is also improved, feeding
It is more smooth.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is partial enlargement Fig. 1 of the utility model；
Fig. 3 is partial enlargement Fig. 2 of the utility model.
Specific implementation mode
Embodiment：
Fig. 1 to Fig. 3 is please referred to, the utility model provides a kind of progressive die for the small angle bending of hardware terminal, including
Upper die and lower die are equipped with material strip between the upper die and lower die.
The material strip is equipped with several stations, and the station includes pre- trimming station 1, trimming station 2 and bending station.
In addition, further including tearing notch station 3, the tearing notch station 3 is arranged in after the pre- trimming station 1.
In the present embodiment, the pre- trimming station 1 includes the cavity plate 11 for going out small angle bending part, can need small angle
The portion profile of bending is cut out.
The bending station includes the small angle bending station 4 for being followed successively by tandem arrangement, preceding 45 degree of bending stations 5,70
Spend bending station 6 and rear 45 degree of bending stations 7.
The low-angle bending station 4 is arranged between the pre- trimming station 1 and trimming station 2, specifically, described small
Angle bending station 4 includes four distribution bending stations 41, wherein preceding 45 degree of bending stations 5 are arranged in the trimming station 2
Later.
In addition, the progressive die further includes cutting waste station 8, it is described to cut the arrangement of waste station 8 45 degree of benders in the rear
After position 7.
Small angle bending progressive die provided by the utility model, it, first will be small by the pre- trimming station being arranged on material strip
Angle needs the portion profile of bending to cut out, then small angle is carried out bending by tearing notch in four times, remaining waste material is then passed through trimming
Station is cut out, and increases the binder area of small angle bending, is had when 45 degree of bendings, 70 degree of bendings and rear 45 degree of bendings before progress
Sufficiently large pressure-plate-force so that bending angle and bending length become more stable, while the intensity of material strip is also improved, feeding
It is more smooth.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited according to this
It is new all should still to belong to this practicality that is, according to equivalent changes and modifications made by the utility model patent range and description for range
In the range of type covers.
