Abstract
The invention discloses a tungsten carbide knurling roll, comprising a knurling roll body, and a rotary shaft arranged in the knurling roll body, wherein a tungsten carbide coating is coated on the surface of the knurling roll body, and a chromium coating is coated outside the tungsten carbide coating. Because the tungsten carbide coating is coated on the surface of the knurling roll body, and the chromium coating is coated outside the tungsten carbide coating, the tungsten carbide knurling roll is good in chemical stability, high in hardness, and excellent in wear-resistant performance, thus greatly increasing the service life; and moreover, the tungsten carbide knurling roll cannot generate deformation after being used for a long time, thus guaranteeing the consistent ideal quality of products.
Description
Technical field
The present invention relates to the knurling rolls field, particularly relate to a kind of tungsten carbide knurling rolls.
Background technology
Knurling rolls are applicable to the ridge design compactings such as plastic sheet, film, aluminium foil, leather, hard plate, wallpaper, floor tile, glass, stationery; improve the product surface aesthetic feeling, strengthen false proof, protection trade mark texts, and can develop according to customer requirement the knurling rolls of different pattern.
Yet existing knurling rolls are generally used the Q235 steel plate, and such knurling rolls are wear-resisting, corrosion resistance is relatively poor, and service life is shorter.
Summary of the invention
The technical problem that the present invention mainly solves provides that a kind of hardness is high, wear-resisting, corrosion-resistant, high temperature resistant, the tungsten carbide knurling rolls of long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of tungsten carbide knurling rolls are provided, comprise the knurling rolls body and be arranged on the intrinsic rotating shaft of knurling rolls, described knurling rolls body surface is coated with tungsten carbide coating, and described tungsten carbide coating is coated with chromium coating outward.
In a preferred embodiment of the present invention, described tungsten carbide coating thickness is 0.06-0.08mm.
In a preferred embodiment of the present invention, described chromium coating thickness is 0.01-0.05mm.
In a preferred embodiment of the present invention, be added with boric acid and magnesia in the described chromium coating.
The invention has the beneficial effects as follows: tungsten carbide knurling rolls of the present invention are owing to be coated with tungsten carbide coating at the knurling rolls body surface, described tungsten carbide coating surface is coated with chromium coating, so that these knurling rolls have good chemical stability, hardness is high, anti-wear performance is excellent, greatly improved service life, and can not produce distortion after using the long period yet, guarantee the uniform desirable quality of product.
Description of drawings
Fig. 1 is the perspective view of tungsten carbide knurling rolls one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, knurling rolls body, 2, rotating shaft, 3, tungsten carbide coating, 4, chromium coating.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
As shown in Figure 1, the embodiment of the invention comprises:
A kind of tungsten carbide knurling rolls comprise knurling rolls body 1 and are arranged on rotating shaft 2 in the knurling rolls body 1 that described knurling rolls body 1 surface is coated with tungsten carbide coating 3, the described tungsten carbide coating 3 outer chromium coatings 4 that are coated with.
Described tungsten carbide coating 3 thickness are 0.06-0.08mm.Tungsten carbide hardness is only second to diamond, has excellent wear-resisting grain mill performance, the service life of having improved these knurling rolls.Described chromium coating 4 thickness are 0.01-0.05mm.Chromium coating 4 has very high hardness, and is different with process conditions according to solution composition, and its hardness can change in 400～1200HV very on a large scale; Chromium coating 4 has preferably heat resistance, and in heating below 500 ℃, its glossiness, hardness have no significant change, and temperature begins to reduce greater than 700 ℃ of hardness greater than 500 ℃ of beginning oxidation stains; The coefficient of friction of chromium coating 4 is little, and particularly dry friction coefficient is minimum in all metals, so chromium coating 4 has good wearability; Chromium coating 4 has good chemical stability, does not all have an effect in alkali, sulfide, nitric acid and most of organic acid.
Be added with boric acid and magnesia in the described chromium coating 4, internal stress is little, and is good with the adhesion of knurling rolls body 1.
Compared with prior art, tungsten carbide knurling rolls of the present invention are owing to be coated with tungsten carbide coating 3 on knurling rolls body 1 surface, described tungsten carbide coating 3 surfaces are coated with chromium coating 4, so that these knurling rolls have good chemical stability, hardness is high, anti-wear performance is excellent, greatly improved service life, and also can not produce distortion after using the long period, guaranteed the uniform desirable quality of product.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
Claims (4)
