Abstract
The utility model provides a cantilever roller way of a steel billet heating furnace, which comprises a roller head and a roller shaft. A groove is arranged at one end of the roller head, a lug boss is arranged at one end of the roller shaft, clamping sleeves are arranged along the radial directions of the roller head and the roller shaft, and the two ends of the clamping sleeves are respectively arranged in the groove of the roller head and at the end face of the lug boss of the roller shaft. The two clamping sleeves are oppositely-open and present the semi-ring type, circular rings are arranged on the outer circles of the clamping sleeves, and set screws are respectively arranged at one side of the outer circles of the clamping sleeves. As the connection between the roller head and the roller shaft adopts the method of axial positioning by the oppositely-open type clamping sleeves, the welding is not needed, thereby fundamentally solving the shedding problem of the roller head and improving the using reliability of the cantilever roller way in the furnace. When the roller head is damaged and needs replacing, only the set screws need to be loosened, the circular rings are dropped out, the clamping sleeves can be loosened, then the roller head which needs replacing can be conveniently taken down, and the entire roller way does not need to be replaced, thereby not only reducing the cost and shortening the assembling time, but also increasing the working efficiency and avoiding the damage of key spare parts in a bearing box of a transmission mechanism and in a speed reduction box when the roller shaft is in assembling and disassembling.
Description
Technical field
The utility model relates to technical field of metallurgical machinery, relates in particular to a kind of billet heating furnace hanging arm roll.
Background technology
At present, in shaped steel at home and abroad and rod, the rod rolling line, often adopt walking beam furnace to carry out the rolling preceding heating of steel billet.Loading end and discharge end at process furnace generally all are provided with hanging arm roll in the stove, are used for going into stove and coming out of the stove of steel billet.Steel billet is sent in the stove by dress steel hanging arm roll in the stove of loading end, by walking beam the steel billet stepping is delivered in the stove of discharge end on the tapping hanging arm roll, finishes the heat-processed of steel billet simultaneously, then by tapping roller-way in the stove it is sent process furnace and is rolled.Hanging arm roll not only will be finished the conveying of steel billet under the condition of high temperature, also will bear the impact that steel billet is caused when roller-way up and down.The driving part of hanging arm roll is installed in outside the stove usually, is reached in the stove by the roll shaft of cantilever, and the roll shaft front end is equipped with the roller head.Usually roll shaft adopts the recirculated water cooling, and the roller head is then made by refractory alloy.The roller head is packed into the end of mostly taking from roll shaft that is connected of roll shaft, adds the weldering block in the roll shaft end then, or takes the form with roller head and the direct welding of roll shaft, keeps the axial location of roller head and roll shaft.The shortcoming of doing like this is: because the block that institute adds weldering cylindrical of high shaft all, cooling performance is bad, very easily ablates, and causes the axial location inefficacy of roller shell, the roller head is come off drop in the process furnace; And the mode that adopts roller head and roll shaft directly to weld, because roll shaft has water-cooled, the roller head does not have water-cooled, both temperature differ bigger, and its swell increment is different, add the shock load of steel billet, very easily cause the weld bond cracking, axial location lost efficacy, and the roller head is dropped in the process furnace.After the roller head drops in the process furnace, snap into moving beam sometimes and decide to cause the accident between the beam, drop to slag-drip opening sometimes,, influence the normal operation of process furnace, also influenced the production operational availability of whole piece rolling line its obstruction.And cause changing whole hanging arm roll because of the roller head damages, also on human and material resources, cause very big waste.
Summary of the invention
The utility model provides a kind of billet heating furnace hanging arm roll, has solved that the roller roller head in the background technology easily comes off, poor stability, the shortcoming of easy-maintaining not.
The technical solution of the utility model is achieved in that a kind of billet heating furnace hanging arm roll, comprise roller head, roll shaft, an end of roller head is established roller head groove, and roll shaft one end is established the roll shaft boss, radially establish cutting ferrule along roller head, roll shaft, the cutting ferrule two ends lay respectively in the roller head groove and the roll shaft raised head face;
Cutting ferrule be two split, semi-ring formula cutting ferrule;
Establish annulus on the cutting ferrule cylindrical;
Cutting ferrule cylindrical one side is established holding screw.
The beneficial effects of the utility model are: because the roller head carries out the mode of axial location with taking the opposite opened cutting ferrule being connected of roll shaft, need not welding, fundamentally solved the roller head problem that comes off, improved the work reliability of the interior hanging arm roll of stove.When the damage of roller head needs to change, only need unclamp holding screw, withdraw from annulus, just can unclamp cutting ferrule, unload the roller head that needs replacing easily, need not to change whole roller-way.So not only can reduce cost, also shorten time of setting-up, improve working efficiency, avoided when the dismounting roll shaft transmission rig bearing case and reduction box in the damage of key components and parts.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, roller head, 2, roll shaft, 3, cutting ferrule, 4, annulus, 5, holding screw, 6, roller head groove, 7, the roll shaft boss.
Specific embodiments
Below in conjunction with accompanying drawing the utility model is further described: a kind of billet heating furnace hanging arm roll, comprise roller head 1, roll shaft 2, one end of roller head 1 is established roller head groove 6, roll shaft 2 one ends are established roll shaft boss 7, radially establish cutting ferrule 3 along roller head 1, roll shaft 2, cutting ferrule 3 two ends lay respectively in the roller head groove 6 and roll shaft boss 7 end faces, cutting ferrule 3 be two split, semi-ring formula cutting ferrule, establish annulus 4 on cutting ferrule 3 cylindricals, cutting ferrule 3 cylindricals one side is established holding screw 5.
Roller head 1 is put roll shaft 2 from the left end of roll shaft 2, the right side of roller head 1 is contacted with the shoulder of roll shaft 2, two semi-rings of cutting ferrule 3 are radially closed along roller head 1, one side in cross section in the cutting ferrule 3 is contacted with the side A of roller head groove 6, the another side contacts with the side B of roll shaft boss 7, so just guaranteed the axial location of roller head 1 on roll shaft 2, after cutting ferrule 3 closes, cylindrical along cutting ferrule 3 advances annulus 4, cutting ferrule 3 just can not unclamp, last holding screw 5 is installed in the screw of cutting ferrule 3 cylindricals, thereby preventing that annulus 4 from moving comes off.
Because the roller head carries out the mode of axial location with taking the opposite opened cutting ferrule being connected of roll shaft, need not welding, fundamentally solved the roller head problem that comes off, improved the work reliability of the interior hanging arm roll of stove.When the damage of roller head needs to change, only need unclamp holding screw, withdraw from annulus, just can unclamp cutting ferrule, unload the roller head that needs replacing easily, need not to change whole roller-way.
