Abstract
The utility model discloses a punching die which comprises an upper die body and a lower die body. The punching die further comprises a thin film releasing device which is provided with a rotatable film rolling device. The film rolling device is provided with a thin film in a rolled mode, wherein the film can be pulled to the place between the upper die body and the lower die body. By means of the punching die, the defect that the surface of a part is coated with lubricating liquid in the time of punching and dragging, and therefore contamination is caused in the prior art is overcome, the punching die does not need to be coated with the lubricating liquid and a part and the die can also be prevented from being scraped.
Description
Technical field
The utility model relates to part punching field.Be specially a kind of diel.
Background technology
In mechanical manufacturing field, cold stamping is to apply a kind of technique very widely.Thereby can material be bent and be extended by cold stamping and form the part of given shape.In the process of punching press and the shaping of extending, the part of mould and punching press pushes and rubs under huge pressure, and the surface of mould and part unavoidably can produce cut, and this not only can cause the low service life that also can affect mould of quality of part.The method that prevents at present part and mould generation cut is to be coated with lubricating fluid at piece surface, but lubricating fluid not only can cause the severe contamination of part and press work environment, also may cause initiation fire under other technological operation operates as welding etc.Even lubricating oil is cleaned and can not thoroughly be decontaminated, and cleaning not only bothers and also causes the efficiency of whole Sheet Metal Forming Technology very low.
Utility model content
The technical problem that the utility model solves is to overcome and is existingly coated with lubricating fluid in punching press and while extending at piece surface and causes the shortcoming of polluting, and a kind of diel that lubricating fluid also can prevent that part and mould from producing cut that do not need to be coated with is provided.
Diel of the present utility model, comprises upper die and lower die, and described diel also comprises film releasing device, and described film releasing device has rotatable film rolling device, and described film rolling device volume has the film that can be pulled between described patrix and counterdie.
As preferably, described film is plastic sheeting.
As preferably, the thickness of described plastic sheeting is 0.02mm-0.1mm.
As preferably, described film rolling device is cylinder, described film releasing device also comprises the fixed axis through described cylinder, and described cylinder can be with respect to described fixed axis rotation, and the two ends of described fixed axis are stretched out from the two ends of described cylinder and are fixedly connected with fixture.
As preferably, described patrix is die, and described counterdie is punch.
As preferably, the size of described film is greater than size and the size to be punched and/or part of extending of described counterdie.
Compared to the prior art diel of the present utility model, has following beneficial effect:
1, diel of the present utility model is in punching press or the process of extending, film forms one deck lubricant between part and counterdie, thereby reduce bend and drawing process in friction between material and mould, reduce resistance of deformation, thereby contribute to reduce drawing coefficient and tensile force, prevent the surperficial quick-wearing excessively of mold work and produce scratch, thereby preventing the generation of cut.Not only can improve the quality of part, also because avoiding using fluid lubricant can not pollute part, simultaneously owing to having deducted matting, also improve operating efficiency.
2, its film adopts plastic sheeting, and its cost is well below the cost of lubricating oil, thereby has reduced the cost of whole punching press or the technique of extending.
3, its film releasing device adopts cylinder and the fixed axis through the hollow space of described cylinder, and the operation of getting film and plastic film mulch is with respect to all simple and fasts more of the operation that is coated with lubricating oil.

The specific embodiment
Fig. 1 is the structural representation of diel of the present utility model, and Fig. 2 is the top view of the diel in Fig. 1.As depicted in figs. 1 and 2, comprise patrix 3 and counterdie 4, described counterdie 4 is located on the workbench 2 of punch press bed body 1, and patrix 3 is positioned at the top of counterdie 4.Described diel also comprises film releasing device 5, and described film releasing device 5 has rotatable film rolling device, and described film rolling device volume has the film 6 that can be pulled to before punching operation between described patrix 3 and counterdie 4.When operation, pull film 6, film rolling device relays out film 6 at the effect backspin of pulling force.Film 6 is pulled to the top of counterdie 4 and completes, on film 6, place part 11 to be punched or that extend.Then matched moulds carries out punching press or extends, after die sinking by film 6 from counterdie 4 in or peel from part 11.
In the present embodiment, on workbench 2, can also be provided with punch press parallels 7, the lower bolster 14 of counterdie 4 is fixed on punch press parallels 7 by pressing plate (not shown), the below of lower bolster 14 is also provided with pressing plate parallels 8, the fixed form of counterdie 4 is existing fixed form, is the normal technological means adopting of those skilled in the art.
Diel of the present utility model is in punching press or the process of extending, film forms one deck lubricant between part and counterdie, thereby reduce bend and drawing process in friction between part 11 and counterdie, reduce resistance of deformation, thereby contribute to reduce drawing coefficient and tensile force, prevent the surperficial quick-wearing excessively of mold work and produce scratch, thereby also preventing the generation of part cut.Diel of the present utility model not only can improve the quality of part, also because avoiding using fluid lubricant can not pollute part, simultaneously owing to having deducted matting, has also improved operating efficiency.
As preferably, described film 6 is plastic sheeting 6, and its cost is also well below lubricating oil, thus the cost that has reduced whole punching press or extended.Its composition can be: polyethylene and/or polypropylene and/or polyvinyl chloride.Certainly film 6 also can adopt other smooth and have a material compared with high-ductility.
As further preferred, the thickness of described plastic sheeting 6 is 0.02mm-0.1mm.In the present embodiment, the thickness of film 6 is 0.05mm.
As preferably, described film rolling device is cylinder 9, and described film releasing device 5 also comprises the fixed axis (not shown) through described cylinder 9.Described cylinder 9 can be with respect to the rotation of described fixed axis, and the two ends of described fixed axis are stretched out from the two ends of described cylinder 9 and are fixedly connected with fixture, fixture can be workbench 2 or punch press parallels 7 or with the fixing fixture in ground.In the present embodiment, the two ends of fixed axis are fixedly connected with the support member (not shown) arranging on punch press parallels 7.Certainly film releasing device 5 also can adopt other structures, as comprises the rotating shaft that cylinder and the both ends of the surface from cylinder are stretched out, and punch press parallels 7 is provided with two support members, and each support member has hole, and rotating shaft pierces in hole and can in hole, rotate.Film releasing device also can only comprise cylinder or circular shaft, and film releasing device can be placed on workbench or in other fixtures, and in the time of oriented film, film releasing device rotates and discharge film under the effect of pulling force.
In the present embodiment, described patrix 3 is die, and described counterdie 4 is punch.Punch comprises holding pad 10 and penetrates the drift 13 of the through hole of holding pad 10, before punching press, when plastic film mulch, film 6 is layered on holding pad 10 and drift 13, and part to be punched is placed on the punch of completing after film.When punching press, plastic sheeting 6 enters in concave die cavity with part simultaneously, and the shape of the inner surface of die has determined the shape of the outer surface of part, and the shape of drift 13 outer surfaces of punch has determined the shape of the inner surface of part.Certainly upper die and lower die can also be the moulds of other shapes.
