Abstract
The utility model discloses a kind of die and diel that does not damage product surface.Wherein, a kind of die that does not damage product surface, its opening part is provided with fillet, and its lower end and an inclined-plane join; Between lower end, inclined-plane and mold cavity surface, be also provided with fillet, inclined-plane and fillet are tangent; Mold cavity surface has gradient.The utility model makes to form gap between die opening part and moulding material, in forming process, the existence in this gap makes material can not touch the opening part of die, thereby has reduced greatly the probability that scraping occurs, and has avoided the bad phenomenon causing because of product surface scratch.
Description
Technical field
The utility model relates to field of machine punching, particularly a kind of die; The utility model also relates to a kind of diel that comprises this die.
Background technology
Punching press is to utilize mould sheet metal to be made to various en plaque parts and housing, container class workpiece on forcing press, or pipe fitting is made to the forming method of various tubular workpieces, because it has the advantages such as production efficiency is high, dimensional accuracy good, material consumption is few, extensively apply to the every field of national economy now.
The mould that punching press is used is called diel, diel divides die and punch, mould causes scratch to product surface when preventing moulding, in prior art, die opening part is generally all provided with fillet, but be limited to fillet and add the approximate structure of facing directly, no matter radiused surface processing is how smooth, all can not stop scratch completely, this for finished surface required precision high or surperficial coated product, will increase extra cost.
utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of die that does not damage product surface, can effectively avoid scraping, and the utility model also provides a kind of diel that comprises this die.
The utility model solves the technical scheme that its technical problem adopts:
Do not damage a die for product surface, its opening part is provided with fillet, and its lower end and an inclined-plane join; Between lower end, inclined-plane and mold cavity surface, be also provided with fillet.
As the further improved procedure of such scheme, inclined-plane and fillet are tangent.
As the further improved procedure of such scheme, mold cavity surface has gradient.
The utility model also provides a kind of diel, and it comprises above-mentioned die and suitable punch with it.
The beneficial effects of the utility model are: between die opening part and moulding material, form gap, in forming process, the existence in this gap makes material can not touch the opening part of die, thereby has reduced greatly the probability that scraping occurs, and has avoided the bad phenomenon causing because of product surface scratch.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the cutaway view of the utility model die;
Fig. 2 is the cutaway view of the utility model diel;
Fig. 3 is the cutaway view of prior art die.
The specific embodiment
With reference to Fig. 1, show the cutaway view of the die 10 of an embodiment of the present utility model, its opening part is provided with fillet 11, and its lower end and an inclined-plane 12 join, and preferred, inclined-plane 12 angles are 45 °; 13 of 12 lower ends, inclined-plane and mold cavity surfaces are also provided with fillet 11.
Preferably, inclined-plane 12 is tangent with fillet 11, in the situation that guaranteeing inclined-plane 12 and hollows 11 surface roughness, can further avoid the generation of scratch.
Further preferred, mold cavity surface 13 has gradient, and its amount of taper is 3 °, makes die cavity present up big and down small shape, and this gradient can make the better break away from moulds of product, prevents that product and mould are adhered and the surface breakdown that causes.
The utility model also provides a kind of diel, with reference to Fig. 2, comprise above-mentioned die 10 and suitable punch 30 with it, the extruding that is subject to punch 30 at moulding material 20 is sunk in process, first it form a gap with inclined-plane, because the existence in this gap, moulding material 20 can not contact with die 10 opening parts, than the fillet of prior art, add the combination of vertical plane or near vertical face, can reduce greatly the probability of scraping.
With reference to Fig. 3, the die of prior art adopts the mode of fillet and vertical plane or the direct transition of near vertical face, and in punching course, moulding material and die opening part are easy to just touch, thereby damage product surface affects product appearance or electric conductivity.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
Claims (4)
1. do not damage a die for product surface, it is characterized in that: comprise die body, described die body is provided with recessed die cavity, and its opening part is provided with fillet, and its lower end and an inclined-plane join; Between lower end, described inclined-plane and mold cavity surface, be also provided with fillet.
2. die according to claim 1, is characterized in that: described inclined-plane and described fillet are tangent.
3. die according to claim 1 and 2, is characterized in that: described mold cavity surface has gradient.
4. a diel, is characterized in that: comprise die as described in any one in claim 1-3 and suitable punch with it.
