Description
Technical field
The present invention relates to blade punching die field, particularly belongs to a kind of double stamping dies of blade.
Background technology
Impeller is also known as active wheel, is significant components in centrifugal pump.Impeller generally comprises wheel disc, wheel cap and blade three parts.
Impeller can be divided into single panel type impeller, circular impeller and aerofoil impeller according to the shape of blade.With circular arc in three kinds of impellers
Shape is most widely used.The blade production of circular impeller is main to rely on punching die to make.Traditional blade punching die is using
When following drawback be present：First, traditional punching die is monolithic punching, punching efficiency is low；Second, traditional punching die exists
Spacing between blade can not be accurately controlled during punching blade, causes raw material largely to waste.The present invention provides regarding to the issue above
A kind of double stamping dies of blade.
The content of the invention
The present invention provides a kind of blade double stamping dies, solves the problems, such as to mention in above-mentioned technical background.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows：
The double stamping dies of a kind of blade, it is characterised in that the double stamping dies of the blade include mould and mould under punching, institute in punching
State mould in punching and rush post, stripper, blade cutting knife, positioning cutting knife and lead, fixed plate including upper bolster, fixed plate, cutting knife
On upper bolster, cutting knife rush it is fixed in post insertion fixed plate, stripper by four leads and fixed plate in succession, blade
In cutting knife insertion stripper, positioning cutting knife is arranged on stripper, has four to be oriented to post holes and two blades on the stripper
Upper cutter hole, lead are embedded in blade upper cutter hole through post holes, blade cutting knife is oriented to, and mould includes lower mould base under the punching
Seat, limited block, blade incision tool bore, the positioning edge of a knife and lead connecting hole, limited block, blade incision tool bore, the positioning edge of a knife and
Lead connecting hole is in lower die base, and when processing blade, mould pushes in punching, and stripper passes through upward on four leads
Mobile, blade cutting knife is gone out the blade raw material that blade upper cutter hole is pointed on blade incision tool bore and is punched, is being punched
While blade, positioning cutting knife punching blade blade raw material edge positions to punching next time.
Preferably, there are multiple buffer springs in the punching in mould between fixed plate and stripper.
Preferably, the blade incision tool bore shares two, and two blade incision tool bores are arranged in inverted image shape, two blades
Spacing is not more than 10mm between incision tool bore, and blade upper cutter hole is identical with blade incision tool bore.
Preferably, during the positioning knife edge length 1.1 times of spacing between two blade incision tool bores.
Compared with the prior art, beneficial effects of the present invention are as follows：
A kind of double stamping dies of blade are combined into by optimizing design to mould under mould in punching and punching, using double
Lamination mould, it is monolithic punching to solve traditional punching die, the low problem of punching efficiency；On double increase positioning cutting knife with
The edge of a knife is positioned, spacing between blade can not accurately be controlled in punching blade by solving traditional punching die, cause raw material big
Measure waste problem.The present invention improves blade processing efficiency, improves raw material utilization rate, and it is good to process blade effect, is adapted to
Produce and blade use is processed in impeller industry.
Brief description of the drawings

Fig. 2 is mould in punching of the present invention.
Embodiment
Referring to accompanying drawing:The double stamping dies of a kind of blade, it is characterised in that the double stamping dies of the blade include mould 1 and punching in punching
Mould 2 under piece, in the punching mould 1 include upper bolster 101, fixed plate 102, cutting knife rush post 3, stripper 105, blade cutting knife 107,
Cutting knife 104 and lead 106 are positioned, fixed plate 102 is arranged on upper bolster 101, and cutting knife rushes post 3 and is embedded in fixed plate 102 admittedly
Fixed, by four leads 106 and fixed plate 102 in succession, blade cutting knife 107 is embedded in stripper 105 stripper 105, positioning
Cutting knife 104 is arranged on stripper 105, there is four holes of lead 106 and two blade upper cutter holes on the stripper 105,
Lead 106 is embedded in blade upper cutter hole through post holes, blade cutting knife 107 is oriented to, and mould 2 includes lower mould base under the punching
Seat 201, limited block 204, blade incision tool bore 203, the positioning edge of a knife 202 and lead connecting hole 205, under limited block 204, blade
Cutting knife hole 203, the positioning edge of a knife 202 and lead connecting hole 205 are in lower die base 201, when processing blade, mould 1 in punching
Push, stripper 105 moves up on four leads 106, and blade cutting knife 107 goes out blade upper cutter hole and is pointed to blade
Blade raw material on incision tool bore 203 are cut, and while cut-off blade, positioning cutting knife 104 cut-off blade blade is former
Edge of materials positions to cutting next time.There are multiple bufferings in the punching in mould 1 between fixed plate 102 and stripper 105
Spring.The blade incision tool bore 203 shares two, and two blade incision tool bores 203 are arranged in inverted image shape, two blade incisions
Spacing is not more than 10mm between tool bore 203, and blade upper cutter hole is identical with blade incision tool bore 203.The positioning edge of a knife 202
During length 1.1 times of spacing between two blade incision tool bores 203.
