Abstract
The invention discloses a kind of sleeve for punch protection structure; including punch-pin, punch retainer, sheath, cylinder pad, backing plate, sheath is arranged on outside punch-pin, and punch-pin and sheath are fixed on punch retainer together; punch-pin length is less than length, and the setting cylinder pad behind punch-pin.The present invention is additionally arranged cylinder mat structure to the punch-pin of aperture diel; it can solve the problem that because punching hole diameter is less than workpiece material thickness; and cause elongated male die easily curved, unstability and this technical problem that fractures; punch-pin is played a protective role; not only increase punch strength; extend Life of Punch Die, and also allow for the processing and replacing of punch-pin.
Description
Technical field
The present invention relates to diel field, and in particular to a kind of sleeve for punch protection structure.
Background technology
When carrying out aperture punching, by institute's hole punched footpath very little, thus piercing punch diameter also very little.If using commonly
Blanking method is punched, easily cause elongated male die bending, unstability and fracture, therefore when rushing aperture, how to improve punch strength, prevent
Its fracture and bend be aperture punching key issue.The side that the current fine male die of prevention in the prior art is fractureed and bent
Method, mainly using punch-pin guide frame, common method has：Local guide frame.In order to ensure that punch-pin and die hole are concentric
It is correct, it is necessary to add auxiliary guide in stripper and punch retainer and cavity plate product with relative position, unloaded using suppressing
Flitch is protected and is oriented to punch-pin.Patent No. ZL201620046663.1, patent name is " aperture diel "
Utility model patent discloses a kind of aperture diel, and blanking punch is played using stripper, guide plate and sleeve for punch
Protective effect.But this structure design is unfavorable for the processing and replacing of punch-pin.Further, since between each component of fine blanking die
Match ratio it is more accurate, the lubricating oil used is very thick, between cavity plate bottom surface and piercing punch, and coordinate accurately it is convex
Confined space is easily formed between die holder and base.During mold movement, the air of enclosed area is difficult to drain rapidly, makes mould knot
Because heat caused by friction is difficult to take away with air between structure, the motion of punch-pin will be influenceed, lower speed of production, even
The phenomenon that product can be caused uneven, influences the ordinary life of fine blanking die, therefore exhaust apparatus should be opened up on mould structure.
The content of the invention
To eliminate this phenomenon, deficiency of the prior art is solved, the present invention provides a kind of sleeve for punch protection structure, energy
It is enough that punch-pin is played a protective role, punch strength is not only increased, extends Life of Punch Die, and also allows for the processing and more of punch-pin
Change.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
A kind of sleeve for punch protection structure, including punch-pin, punch retainer, sheath, cylinder pad, backing plate, sheath are arranged on punch-pin
Outside, punch-pin and sheath are fixed on punch retainer together, it is characterised in that：Punch-pin length is less than length, and convex
Cylinder pad is set behind mould.
It is preferred that, a kind of foregoing sleeve for punch protection structure, its punch-pin length is less than length 5mm.
It is preferred that, a kind of foregoing sleeve for punch protection structure, its cylinder pad passes through riveting method or frictional connection with punch-pin.
It is preferred that, a kind of foregoing sleeve for punch protection structure, its cylinder pad diameter is more than convex mould diameter.
It is preferred that, a kind of foregoing sleeve for punch protection structure, its punch-pin and cylinder pad coordinate with sheath gap.
It is preferred that, a kind of foregoing sleeve for punch protection structure opens up passage on punch retainer and/or sheath.
The beneficial effect that the present invention is reached is：
The present invention provides a kind of sleeve for punch protection structure, can solve the problem that because punching hole diameter is less than workpiece material thickness, and causes elongated
Punch-pin easily curved, unstability and this technical problem that fractures, play a protective role to punch-pin, not only increase punch strength, extend
Life of Punch Die, and also allow for the processing and replacing of punch-pin.
Brief description of the drawings
Fig. 1 is the sleeve for punch protection structure schematic diagram that the present invention is provided.
Fig. 2 is cylinder pad and punch structure schematic diagram in Fig. 1.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As described in Figure 1, a kind of sleeve for punch protection structure that the present invention is provided, including punch-pin 4, punch retainer 2, sheath
3rd, cylinder pad 5, backing plate 1, sheath 3 are arranged on the outside of punch-pin 4, and punch-pin 4 and sheath 3 are fixed on punch retainer 2 together,
Cylinder pad 5 is set behind punch-pin 4, and the diameter of cylinder pad 5 is more than the diameter of punch-pin 4；The length of punch-pin 4 is less than the length of sheath 3
Spend 5mm；Cylinder pad 5 is connected with punch-pin 4 by riveting method or frictional connection mode；Punch-pin 4 and cylinder pad 5 are between sheath 3
Gap coordinates；Passage is opened up on punch retainer 2 and/or sheath 3.
In the specific implementation, in blanking process, sheath is not separated the present invention with punch retainer all the time, plays lead
Position-limiting action.When upper mould is pushed, punch-pin stretches out punching from sheath, and part pressure is decomposed by the cylinder pad of punch-pin rear end
Power, improves the intensity of punch-pin, prevents punch-pin from bending in pressurized process impaired；Simultaneously in maintenance process, it is only necessary to by this portion
Divide punch-pin to remove to change, be easy to the processing and replacing of punch-pin.
The present invention provides a kind of sleeve for punch protection structure, can solve the problem that because punching hole diameter is less than workpiece material thickness, and causes
Elongated male die easily curved, unstability and this technical problem that fractures, play a protective role to punch-pin, not only increase punch strength,
Extend Life of Punch Die, and also allow for the processing and replacing of punch-pin.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
