Abstract
The utility model provides a composite bound hard alloy milling roller. The utility model is characterized in that a plurality of segmented hard alloy roll sleeves are sheathed on a general rolled steel roller core; heat-proof high strength adhesive layers between the segmented hard alloy roll sleeves and general rolled steel roller core and among the segmented hard alloy roll sleeves; both ends of the roller core are respectively provided with a check ring which is isodiametric to the hard alloy roll sleeve. The utility model has the characteristics of reasonable structure, convenient manufacture and installation, material saving, process and installation time saving, tight fit among components, high binding strength, longer service life, conspicuous using effect, higher production efficiency, etc. The utility model can take the place of a metallurgy composite roller and traditional composite rollers.
Description
The utility model relates to a kind of shape and structure that the sleeve roll is arranged, especially a kind of compound sticking hard alloy roll.
Roll be metallurgical and mechanical processing industry in a kind of equipment commonly used parts in addition, also be the industrial materials that a kind of rapid wear easily consumes.Because they are operated under the mal-condition of high temperature, high pressure over a long time, its service life is often very short.Especially when rolling harder steel, the degree of injury of roll and the rate of wear are appreciable.Common way can only be to change the easily parts in addition of consumption of these rapid wears continually, not only wastes a large amount of industrial materials but also waste the plenty of time, falls end production efficiency.Chinese patent CN2203194Y discloses a kind of " composite roller ", its technical characterictic is to make of tungsten carbide on the composite roll basis of contact rolled piece roll surface, adopt between the roller core of roll and the roller shell structure by concavo-convex intersection combination, roller shell is a tungsten carbide material, and placing the periphery of roller core, roller core is with the linear expansion coefficient metal material making the same with tungsten carbide.Though this composite roller has long service life, its processing and manufacturing complexity, matching requirements are higher.Particularly producing large-scale roller in particular cases, its processing and manufacturing and assembling are all quite difficult, and compactness that its machinery cooperates is difficult to guarantee.
The purpose of this utility model just is to overcome above-mentioned weak point of the prior art, proposing a kind of structure is provided with rationally, it is convenient to make and install, save material and processing and installation time, each closely cooperating property of parts is strong, the adhesion strength height, longer service life, the remarkable and higher compound sticking hard alloy roll of production efficiency of result of use.
The purpose of this utility model can reach by implementing following technical proposal: be with the carbide alloy roller shell of some joint segmentations on common steel roll core, save therebetween and respectively between the carbide alloy roller shell of segmentation and be provided with heat-resistance high-strength degree adhesive linkage.In order to obtain better result of use, the utility model can also further be taked following measures: the two ends at above-mentioned roll core are provided with and the isometrical back-up ring of carbide alloy roller shell, and by adhesive linkage it are connected with the carbide alloy roller shell with the roll core; On the faying face between above-mentioned roll core and carbide alloy roller shell and the back-up ring, have axial non-slip groove,, avoid it to rotate mutually to strengthen its adhesive strength; Having the saw shape tooth that along the circumferential direction distributes between the carbide alloy roller shell of every joint segmentation and on the faying face between itself and the back-up ring, to strengthen its integral coherence.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is done to describe in further detail.On common steel roll core 1, be with the carbide alloy roller shell 2 of two joint segmental machining, the two ends of roll core 1 are provided with and are with the common iron back-up ring 3 isometrical with this carbide alloy roller shell 2, between roll core 1 and carbide alloy roller shell 2, the back-up ring 3 and respectively save between the carbide alloy roller shell 2 of segmentation and the back-up ring 3 and be provided with heat-resistance high-strength degree adhesive linkage 4.On the faying face between above-mentioned roll core 1 and carbide alloy roller shell 2, the back-up ring 3, have axial non-slip groove 5, having the saw shape tooth 6 that along the circumferential direction distributes between the carbide alloy roller shell 2 of every joint segmentation and on the faying face between itself and the back-up ring 3.When using the utility model product, can select the quantity of carbide alloy roller shell 2 and the width of back-up ring 3 according to the length of roll, by heat-resistance high-strength degree adhesive linkage 4 it is closely linked.Simultaneously, prevent sliding stop, strengthen interconnecting by means of non-slip groove between them 5 and saw shape tooth 6.
The utility model has structure and arranges rationally compared with prior art, and it is convenient to make and install, Save material and processing, installation time, each closely cooperating property of parts is strong, adhesion strength height, service life Longer, result of use significantly and production efficiency high more can be used to metallurgical compound the rolling of replace imported Roller and traditional composite roll.
