Property deformation, thus obtaining the forming and machining method of the workpiece of required form and size.Diel abbreviation punch die, is to criticize material
Amount is processed into the specific purpose tool of required stamping, is installed on forcing press, mould carries in the presence of punching press power during use
The folding of dynamic upper die and lower die and material is punched out wait processing.
In existing punching process, typically red needle is set in upper mould, lower mould arranges corresponding punching, stays after punching press
Foil fall into punching, but foil is easily stuck in punching, the normal use of impact stamping machine, therefore, needs in time
Cleaning foil, but cleaning can waste the plenty of time, reduces production efficiency, simultaneously also cumbersome.Patent No.
" ZL200920074272.0 ", the patent of invention of entitled " with the diel of sheet collecting device " is in the lower section of diel
One sheet collecting device of setting, the foil of the in the hole that can liquidate automatically takes out recovery.This invention includes upper die and lower die,
Upper mould is provided with red needle, and lower mould is provided with the punching corresponding with red needle, and red needle lower end is provided with blows afloat hole, and upper mould is provided with and blows
Play the admission line of hole connection.When stamping machine works, admission line is connected with gases at high pressure, and red needle blows afloat the downward mould in hole
Punching in blow so that the foil in punching is blown punching it is ensured that punching is not blocked.But, gases at high pressure
Using presence necessarily danger, and gas cannot recycle, relatively costly.
Content of the invention
It is an object of the invention to：The foil producing for above-mentioned punching press is easily stuck in the problem in punching, the present invention
A kind of diel being easy to collection thin slice is provided.
The technical solution used in the present invention is as follows：
A kind of diel being easy to collection thin slice, includes mould, red needle, lower mould and die shoe, institute from top to bottom successively
Stating mould is dynamic model, and the bottom of mould is fixed in one end of red needle, and lower mould is provided with the punching corresponding with described red needle, described
Punching is through hole, and punching includes linkage section, changeover portion and punching main body, described linkage section and the punching being sequentially communicated from top to bottom
Main body is cylinder, and changeover portion is taper, and the diameter of described linkage section matches with red needle, the diameter on described changeover portion top and
Linkage section is identical and diameter of changeover portion is from top to bottom incremented by along its axis, the diameter of described punching main body and changeover portion bottom
Diameter identical.Punching on lower mould is designed as three sections by the present invention, including the linkage section being sequentially communicated from top to bottom, changeover portion
With punching main body, on the one hand the diameter of linkage section is matched with red needle can make punching be smoothed out, and on the other hand ensure generation
Foil can enter in linkage section, and the height of linkage section is less, and foil will not be stuck in linkage section.Changeover portion straight
Footpath is from top to bottom incremented by along its axis and the diameter of punching main body is identical with the diameter of changeover portion bottom, i.e. changeover portion and punching
The diameter of main body be all higher than foil it is ensured that foil can be directly entered after linkage section and pass through changeover portion and
Punching main body, without being stuck in punching.
Described die shoe is provided with the first through hole connecting with punching main body, and first through hole is used for the metal falling from punching
Thin slice passes through, and is easy to recycle.
The aperture of described first through hole is more than punching main body it is ensured that foil smoothly enters first through hole, it is to avoid gold
Belong to thin slice to be stuck between lower mould and die shoe.
It is provided with Material collecting box for harvesting below described first through hole.Eventually entered into by the foil of punching and first through hole and gather materials
Case, to recycle.
Described red needle and upper mould are to be welded to connect.Welding has that saving metal, productivity ratio is high, easy-operating feature, and
It is welded and fixed more stable, intensity is higher.
Described red needle is high-speed steel, and the hardness of high-speed steel, wearability, comprcssive strength and bearing capacity are all very high, using height
Fast steel can effectively extend the service life of this diel.
In sum, due to employing technique scheme, the invention has the beneficial effects as follows：There is provided one kind be easy to collect thin
The diel of piece, the punching on this lowing die for stamping die includes linkage section, changeover portion and the punching being sequentially communicated from top to bottom
Main body, and so that the diameter of changeover portion is from top to bottom incremented by so that the foil falling into punching will not be stuck in punching along its axis
Interior, punching efficiency can be improved, and structure is simple, safe and reliable, low cost.
