Abstract
The utility model provides a tool capable of reducing metal pollution. The tool comprises an upper tool and a lower tool which are fitted one above the other, wherein the upper tool and the lower tool are arranged in a staggered way; the side face of the lower tool is provided with an open groove; and a magnetic bar is embedded into the open groove. In the tool capable of reducing metal pollution, the magnetic bar is arranged on the lower tool and can be used for adsorbing metal substances such as iron power or iron scraps and the like caused by friction, so that product pollution is reduced, and the clearness of a product is increased; and moreover, the tool has the a self-cleaning function, the friction coefficient between the upper tool and the lower tool can be reduced, and the service life of the tool is prolonged.
Description
Technical field
The utility model relates to a kind of cutter, can reduce the cutter that resultant metal pollutes when relating in particular to a kind of the shearing.
Background technology
The CCL industry is had relatively high expectations to bonding sheet, the copper coin high-insulativity of its production at present, so the cleanliness factor of product requires also to improve relatively.The friction of product and equipment can produce the material of conductive iron powder and other conductions (iron filings that come out of general wearing and tearing are very little in process of production; Naked eyes are difficult to observe); And the mutual fricative iron powder of shearing tool is great pollution sources on the production line, because cutter is alloy material, generation iron powders such as the mutual shearing friction of the upper and lower cutter of shear history, collision very easily are attached to the surface of bonding sheet, Copper Foil etc.; Cause contamination of products, very easily cause PCB circuit board internal short-circuit.
Based on above-mentioned defective, be badly in need of a kind of cutter that reduces metallic pollution of design, to avoid the pollution that produces in the shear history, thereby make the cleanliness factor of product higher, quality is more guaranteed.
The utility model content
The purpose of the utility model is to provide a kind of cutter that reduces metallic pollution, through establishing magnetic stripe at following cutter, can reduce contamination of products to adsorbing because of metallicses such as fricative iron powder or iron filings when shearing, and improves the cleanliness factor of product.
For realizing above-mentioned purpose, the utility model provides a kind of cutter that reduces metallic pollution, comprising: the upper slitter that suits up and down reaches cutter down, and this upper slitter is crisscross arranged up and down with following cutter, and the side of following cutter is provided with fluting, is inlaid with magnetic stripe in it.
Also be provided with at a distance from magnetosphere between said magnetic stripe and the fluting inner surface.
The beneficial effect of the utility model: the cutter of the minimizing metallic pollution of the utility model, through establishing magnetic stripe, can reduce contamination of products to adsorbing when shearing because of metallicses such as fricative iron powder or iron filings at following cutter, improve the cleanliness factor of product; And the utility model also has self-cleaning function, can reduce the coefficient of friction between the upper and lower cutter, improves service life.
In order further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through the specific embodiment the utility model, the technical scheme that makes the utility model and other beneficial effect is obvious.
In the accompanying drawing,
Fig. 1 is the cross-sectional view of cutter (when suiting) of the minimizing metallic pollution of the utility model.
The specific embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with the preferred embodiment and the accompanying drawing thereof of the utility model.
As shown in Figure 1, the cutter of the minimizing metallic pollution of the utility model comprises: the upper slitter 1 that can suit up and down reaches cutter 2 down, and this upper slitter 1 is crisscross arranged up and down with following cutter 2, and when upper and lower cutter 1,2 suited, its shear surface was tangent.Especially, the said side (shear surface) of cutter 2 down is provided with fluting 20, is inlaid with magnetic stripe 22 in it, and magnetic stripe 22 can adopt the permanent magnetic strip of high magnetic, can use for a long time.In the present embodiment, the side of following cutter 2 is provided with a fluting 20, and fluting 20 length in the vertical is as the criterion with the shearing function that does not influence shear surface less than shear surface length.
Said upper and lower cutter 1,2 reaches down through upper cutter head respectively, and tool rest is installed on the shearing machine; When product such as bonding sheet or Copper Foil etc. are sheared, upper and lower cutter 1,2 respectively from upper and lower downwards, the top shears, when its during because of friction generates iron powder or iron filings; Under the double action of gravity and shearing force; Iron powder or iron filings can be fine by 22 absorption of the magnetic stripe on the following cutter 2, thereby avoid metallicses such as iron powder or iron filings to be adsorbed on the product, reduce the product foreign material and pollute.
In sum, the cutter of the minimizing metallic pollution of the utility model through establishing magnetic stripe at following cutter, can reduce contamination of products to adsorbing because of metallicses such as fricative iron powder or iron filings when shearing, and improves the cleanliness factor of product; And the utility model also has self-cleaning function, can reduce the coefficient of friction between the upper and lower cutter, improves service life.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technical scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection domain of the utility model claim.
Claims (2)
1. a cutter that reduces metallic pollution is characterized in that, comprising: the upper slitter that suits up and down reaches cutter down, and this upper slitter is crisscross arranged up and down with following cutter, and the side of following cutter is provided with fluting, is inlaid with magnetic stripe in it.
2. the cutter of minimizing metallic pollution as claimed in claim 1 is characterized in that, also is provided with at a distance from magnetosphere between said magnetic stripe and the fluting inner surface.
