Abstract
The utility model relates to a jacketed milling roller. The milling roller is a primary mechanical component for solid breaking and abrading at present time. Although the surface of existent milling rollers is overlay welded with wear-resistant steel, the broken-in surface will still be abraded during using process and recession problem occurs. The current restore method is to repair-weld at the abraded pit, but the metallic structure of the surface metal will generate irreversible changes and the entire roller may be out of use. The product comprises a roller body 1 whose surface is fixed with a wear-resistant steel sleeve 2 or a structure steel sleeve 2 with a wear-resistant padding layer. The product can be used under the condition in expecting to elongate the service life of the roller and reduce the abrasion cost.
Description
Technical field: the utility model relates to a kind of by changing the grinding roller that parts are repaired working face.
Background technology: grinding roller is the main mechanical component of present solid fragmentation, grinding.Though the built-up welding of abrasion-resistant stee has been carried out on existing grinding roller surface, in use broken-in surface must also can wear and tear, and cave in, so that influence grinds effect.The mode of repairing is in the pit repair welding at present, but through after 2-3 the repair welding, the structure of surface metal can not have reversible variation, even can integral body peel off in loading process, makes whole grinding roller scrap.The mining of China, coal processing industry, grind occasion at solid fragmentations such as grain processing industry, annually all will scrap such grinding roller in a large number, and just damaged surfaces is just scrapped whole grinding roller, has caused a large amount of physical wastes.
Summary of the invention: the purpose of this utility model provides a kind of grinding roller that adopts replaceable surface mill cover, to prolong the service life of grinding roller, economizes on resources.-
Above-mentioned purpose realizes by following technical scheme:
The band cover roller of milling, its composition comprises: the grinding roller body is fixed with the structure steel bushing of wear-resisting steel bushing or band wearable overlay on the working face of described grinding roller body.
The above-mentioned band cover roller of milling adopts interference fits or interference fit between described grinding roller body and the described steel bushing.
The above-mentioned band cover roller of milling adopts pin or plug welding to be fixedly connected between described grinding roller body and the described steel bushing.
This technical scheme has following beneficial effect:
1. whole wear-resisting steel bushing is adopted in the outside, improved the thickness on surface strength and high-strength surface, slowed down the rate of wear, even adopt the structure steel bushing of band overlay cladding, owing to adopted the branch body structure, when the surface of steel bushing is worn, when repair welding can not continue to use for three to four times, still can continue by the steel bushing that more renews to use original main body, thus the service life of significantly having improved the grinding roller main body.
2. this product has significantly reduced manufacturing, maintenance cost, has reduced the industrial cost of coal, ore, grain and various solid fragmentations, has reduced entire society's production cost.
3. adopt interference fits or interference fit between grinding roller body and the described steel bushing, make combination between the two closely, the generation pine cover of avoiding producing relative rotation weares and teares, and reduces energy consumption.
4. adopt pin or plug welding to be fixedly connected between described grinding roller body and the described steel bushing, guarantee that exhausted nothing relatively rotates, and avoids unnecessary energy consumption between the two.
5. adopt pin or trip bolt to connect, can dismantle overcoat easily, be fit to change frequent or stressed little occasion.
6. adopt plug welding to connect, when changing the steel bushing of outside, need to bore and open the plug welding point, plug welding again after changing steel bushing again and changing because shearing point is many, can be born bigger moment of torsion, occasion that suitable diameter is bigger and the not too frequent occasion of steel bushing replacing.Grinding roller length is bigger or stressed bigger, also can plug welding and excessive two kinds of fixed forms and the usefulness of cooperating.
Description of drawings: accompanying drawing 1 is the structural representation (middle is the plug welding structure, and there is pin at two ends) of this product.
Accompanying drawing 2 is left views (threaded fastener) of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
A kind of band cover roller of milling, its composition comprises: grinding roller body 1, be with the steel bushing 2 of abrasion-resistant stee on the working face of described grinding roller body, adopt interference fits or interference fit between described grinding roller body and the described wear-resisting steel bushing.
Embodiment 2:
A kind of band cover roller of milling, its composition comprises: grinding roller body 1 is with the structure steel bushing 2 of band wearable overlay, employing interference fits or interference fit between described grinding roller body and the described steel bushing on the working face of described grinding roller body.
Embodiment 3:
Stressed when little, also can connect with connector, adopt mode movingly between promptly described grinding roller body and the described steel bushing, end face connects with connector.
Embodiment 3:
A kind of band cover roller of milling, its composition comprises: grinding roller body 1, be with the steel bushing of abrasion-resistant stee or the structure steel bushing 2 of band wearable overlay on the working face of described grinding roller body, has plug welding hole 4 on the steel bushing He on the grinding roller body, adopt and the corresponding structural steel electrode plug welding of grinding roller body material the bottom, the abrasion-resistant stee welding rod plug welding that adapts with steel bushing is adopted on the surface, makes on the steel bushing and is fixedly connected on the grinding roller body.When 3-4 build-up wear-resistant steel of steel bushing experience wear repair welding can not continue to use, when needing to change steel bushing, plug welding place can be bored and open, take off steel bushing, put new steel bushing and be connected and fixed by plug welding again.
Claims (3)
1. a band overlaps the roller of milling, and its composition comprises: the grinding roller body is characterized in that: the structure steel bushing that is fixed with wear-resisting steel bushing or band wearable overlay on the working face of described grinding roller body.
2. the band cover according to claim 1 roller of milling is characterized in that: adopt interference fits or interference fit between described grinding roller body and the described steel bushing.
3. the band cover according to claim 1 and 2 roller of milling is characterized in that: adopt pin or plug welding to be fixedly connected between described grinding roller body and the described steel bushing.
