Abstract
The invention relates to a wear-prevention stamping die comprising an upper die set and a lower die set matched with the upper die set correspondingly, wherein the upper die set is provided with a punch, the lower die set is provided with a concave die plate, the part, corresponding to the punch, of the concave die plate is provided with a through hole, the upper half part of the through hole is a cut part, the lower half part of the through hole is a blanking part of which the aperture is expanded outward, the inner side of the cut part is uniformly coated with a high-strength elastic composite layer, and the elastic shrinkage range of the high-strength elastic composite layer is minus 0.002mm to plus 0.002mm. As the high-strength elastic composite layer is arranged, on the one hand, the one-side gap of the wear-prevention stamping die can be adjusted due to the shrinkage property, on the other hand, one-side wear and one-side scratching and pressing can be effectively prevented.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of diel of wear prevention.
Background technology
On the concave template of existing diel, offer a through hole, the top of through hole is a blade portion, and blade portion is a straight hole, and the bottom of through hole is aperture abducent blanking section.The aperture of blade portion is designed to measure-alike zero clearance with the diameter of drift and coordinates.During punching press, error due to upper and lower module guiding accuracy, drift and blade portion coordinate and there will be certain deviation, while causing the drift punching press and blade portion monolateral scraping and monolateral excessive wear appears, so not only can affect the service life of diel, also can affect crudy and the efficiency of product, also improve the requirement to the machining accuracy of diel.
According to a kind of diel that Chinese patent CN 202725820 U announce, it is identical with the drift size by the top by blade portion, and the bottom of blade portion is straight hole, and aperture is greater than the diameter of drift.Monolateral scraping and monolateral inordinate wear still can't be thoroughly eliminated in the improvement of this structure.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of diel of wear prevention.
The present invention is achieved through the following technical solutions:
A kind of diel of wear prevention, comprise module on one and one and the lower module of the mutual corresponding matching of upper module, on described upper module, be equiped with a drift, on described lower module, be equiped with a concave template, the corresponding drift of described concave template place offers a through hole, the first half of described through hole is blade portion, and the Lower Half of described through hole is aperture abducent blanking section, and the inboard of described blade portion is uniformly coated with a high strength elastic composite bed.
Further, before when drift, the blade portion of through hole being tried punching, the diameter of described blade portion is slightly less than the diameter of drift.
Further, after when drift, the blade portion of through hole once being tried punching, the diameter of described blade portion is identical with the diameter of drift.
Further, the elastic shrinkage scope of described high strength elastic composite bed be-0.002mm ~+0.002mm.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by the high strength elastic composite bed is set, on the one hand according to its monolateral gap of shrinkage adjuster, can prevent effectively that on the other hand it from uneven wear and monolateral scraping occurring.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
The diel of described a kind of wear prevention, comprise module on one and one and the lower module of the mutual corresponding matching of upper module, on described upper module, be equiped with a drift 1, on described lower module, be equiped with a concave template 2, the corresponding drift of described concave template 21 place offers a through hole, the first half of described through hole is blade portion 3, the Lower Half of described through hole is aperture abducent blanking section 4, the inboard of described blade portion 3 is uniformly coated with a high strength elastic composite bed 5, and the elastic shrinkage scope of described high strength elastic composite bed 5 is-0.002mm ~+0.002mm.
Before the blade portion 3 of 1 pair of through hole of drift was tried punching, the diameter of described blade portion 3 was slightly less than the diameter of drift 1, and after the blade portion 3 of 1 pair of through hole of drift was once tried punching, the diameter of described blade portion 3 was identical with the diameter of drift 1.
The present invention, by high strength elastic composite bed 5 is set, on the one hand according to its monolateral gap of shrinkage adjuster, can prevent effectively that on the other hand it from uneven wear and monolateral scraping occurring.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
