Abstract
The utility model discloses a novel wear -resisting embossing roller structure, including embossing roller that is used for extremely thin material knurling and the tungsten carbide coating who increases embossing roller working face hardness, the tungsten carbide coating parcel is on embossing roller working face surface. The utility model discloses an one deck tungsten carbide coating brazes on the working face of embossing roller for the stereoplasm point of embossing roller working face when the wearing and tearing of work quilt is difficult to drop, makes whole embossing roller have very high wearability and bending strength, while tungsten carbide coating is the zero porosity almost, and under the condition that need not other method hole sealings, the corrosion resistance of coating and 304 stainless steels match, are superior to chromium -plated layer, through the tungsten carbide coating that brazes on the embossing roller surface, not only increased the life and the hardness of embossing roller, also guaranteed the quality of knurling simultaneously, satisfy the operation requirement.
Description
Technical field
This utility model relates to a kind of knurling rolls, in particular a kind of novel wear resistant knurling rolls structure.
Background technology
In napkin embossing machine, napkin between knurling rolls and the smooth roll of another high rigidity by thus
Complete embossing.Being very close to each other between knurling rolls and smooth roll, under hydraulic booster, two rollers are steel pair
Steel is directly to pressure.The place contacted with smooth roll due to knurling rolls is the little burr of area or salient point, convex
Spot diameter generally only has ￠ 0.6-0.8, and therefore burr or bump part not only need the highest wearability, and
And need the highest bending strength, just can be not broken.Existing knurling rolls work surface uses the time long
Abrasion easily occurs after, affects the service life of knurling rolls.
Therefore, prior art has yet to be improved and developed.
Utility model content
The purpose of this utility model is to provide a kind of novel wear resistant knurling rolls structure, it is intended to solve existing
Knurling rolls work surface use time length after abrasion the most easily occurs, affect knurling rolls service life
Problem.
The technical solution of the utility model is as follows:
A kind of novel wear resistant knurling rolls structure, wherein, including for very thin material embossing knurling rolls and
Increasing the tungsten carbide coating of knurling rolls work surface hardness, described tungsten carbide coating is wrapped in knurling rolls work
Surface, face.
Described novel wear resistant knurling rolls structure, wherein, described tungsten carbide coating passes through soldering in embossing
The surface of roller work surface.
Described novel wear resistant knurling rolls structure, wherein, the thickness of described tungsten carbide coating is 0.3-0.5
mm。
The beneficial effects of the utility model: this utility model is tied by providing a kind of novel wear resistant knurling rolls
Structure, by one layer of tungsten carbide coating of soldering on the work surface of knurling rolls so that knurling rolls are at work quilt
During abrasion, the Hard Inclusion of work surface is not easy to come off so that whole knurling rolls have the highest wearability and
Bending strength；Tungsten carbide coating is almost without hole simultaneously, in the case of without additive method sealing of hole,
The corrosion resistance of coating is suitable with 304 rustless steels, is better than chromium coating；By in the soldering of knurling rolls surface
Tungsten carbide coating, not only adds service life and the hardness of knurling rolls, also ensure that embossing simultaneously
Quality, meets and uses requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel wear resistant knurling rolls structure in this utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to
Accompanying drawing develops simultaneously embodiment to this utility model further description.
As it is shown in figure 1, a kind of novel wear resistant knurling rolls structure, including the pressure for very thin material embossing
Flower roller 100 and the tungsten carbide coating 200 of increase knurling rolls 100 work surface hardness, described tungsten carbide coating
200 are wrapped on knurling rolls 100 work surface.
Novel wear resistant knurling rolls structure in the technical program is for the embossing of the very thin materials such as napkin, pressure
Flower roller 100 directly contacts pressure with support roller.
In the present embodiment, described tungsten carbide coating 200 passes through the soldering table at knurling rolls 100 work surface
Face.
In order to meet hardness requirement, save material as much as possible simultaneously, in the present embodiment, described carbonization
The thickness of tungsten coating 200 is 0.3-0.5mm.
In the technical program, knurling rolls 100 use alloy die steel CR12MOV or 9CR2MO,
After quenching, carry out polish and carved pattern forms；Knurling rolls 100 roll surface after sandblasting,
(tungsten carbide and NI60 weight ratio are tungsten carbide and NI60 alloy powder to use supersonic spray coating equipment
1:1-5) with 2 times of velocity of sound even application on knurling rolls 100 surface, form the carbon of thickness 0.3-0.5MM
Change tungsten coating 200, then with oxy-acetylene flame or high-frequency heating tungsten carbide coating 200 local warming
To 1000 DEG C, tungsten carbide coating 200 is made to form metallurgical binding, bond strength with knurling rolls 100 roll body
Reach more than 200MPA；Tungsten carbide and the NI60 (nickel chromium triangle of high rigidity in tungsten carbide coating 200 simultaneously
Borosilicate alloy powder) combine together, make WC (tungsten carbide) and CrC (carbon in tungsten carbide coating 200
Change chromium), the hard phase such as CrB (chromium boride) and Ni form the metallurgical binding of high intensity, at tungsten carbide
When coating 200 is worn away, Hard Inclusion is not easy to come off, and therefore tungsten carbide coating 200 has the highest resistance to
Mill property and bending strength；Tungsten carbide coating 200 is almost without hole simultaneously, without additive method sealing of hole
In the case of, the corrosion resistance of tungsten carbide coating 200 is suitable with 304 rustless steels, is better than chromium coating.
In the technical program, coating consistency ≈ 100% of described tungsten carbide coating 200, the toughness of coating
Good, the tungsten carbide coating 200 of knurling rolls 100 is after fine grinding 0.1MM, and burr part can be polished,
Dimpled portions still retains decorative pattern clearly, reaches to use requirement.
The technical program is by one layer of tungsten carbide coating of soldering on the work surface of knurling rolls so that embossing
Roller Hard Inclusion of work surface when work is worn away is not easy to come off so that whole knurling rolls have the highest
Wearability and bending strength；Tungsten carbide coating is almost without hole simultaneously, without additive method sealing of hole
In the case of, the corrosion resistance of coating is suitable with 304 rustless steels, is better than chromium coating；By in embossing
Roller surface soldering tungsten carbide coating, not only adds service life and the hardness of knurling rolls, also protects simultaneously
Demonstrate,prove the quality of embossing, met and use requirement.
It should be appreciated that application of the present utility model is not limited to above-mentioned citing, common to this area
For technical staff, can be improved according to the above description or be converted, all these modifications and variations
All should belong to the protection domain of this utility model claims.
