Abstract
The utility model discloses a carbon sleeve fixation device. The device comprises a roller core which is sleeved with a carbon sleeve. The carbon sleeve fixation device is characterized in that a plurality of card slots are arranged on two ends of the carbon sleeve along the radius direction of the cross section of the carbon sleeve; the roller core on two ends of the carbon sleeve is further sleeved with a multi-claw chuck; the inner side end of the multi-claw chuck is provided with a plurality of claws along the radius direction of the cross section of the multi-claw chuck; the plurality of claws correspond to the plurality of card slots one by one; the multi-claw chuck is fixedly connected with the roller core via a radial fastening bolt. The carbon sleeve fixation device disclosed by the utility model is convenient to mount and dismount; the radial swing of the card sleeve in continuous annealing production processes of strip steel is avoided; the multi-claw chuck with claws can be used for well protecting the end part of the carbon sleeve so that the carbon sleeve is not easy to wear out and stably runs and off tracking of the strip steel is avoided; therefore, the shape and the surface quality of the annealed strip steel can be improved, the service lives of the carbon sleeve and the roller core are long, the production efficiency can be increased, and the production cost can be reduced.
Description
Technical field
The utility model relates to continuous strip annealing furnace carbon and overlaps technical field, concrete refers to a kind of carbon sleeve fixture mechanism.
Background technology
At present, what in continuous strip annealing furnace, carbon cover and roller core great majority adopted is snap ring-type locking latches, it is a pair of draw-in groove of the each processing in carbon cover two ends, the direction of two ends draw-in groove is mutually vertical, roller core wherein has two oval pins on one end, just coordinate with the draw-in groove of carbon cover, the other end of carbon cover adopts snap ring to fix, snap ring is connected with bolt with roller core, and then fix snap ring by spot welding, can only make like this bolt become as a whole with snap ring, between snap ring and roller core, between roller core and carbon cover, still exist loosening.Adopt fixing in this way carbon cover fluctuation of service, usually because carbon cover internal diameter is bigger than normal, axle center external diameter is less than normal, while causing carbon cover to run up, also can produce the swing of certain amplitude in its radial direction, particularly at low-temperature zone and the cooling section of annealing furnace, even if also can there is radially wobbling of nearly 5mm in the carbon of dimensioned cover and axle center according to the rules, cause steel band to back side sideslip, belt steel product template is bad, surface quality is unstable, have a strong impact on production efficiency, bring a lot of problems to situ production, cause tremendous economic loss to Dai Gang manufacturing enterprise.
Summary of the invention
For the problem existing in current snap ring-type carbon sleeve locking apparatus, the purpose of this utility model will provide a kind of carbon sleeve fixture mechanism exactly, solved between snap ring and roller core, loosening problem between roller core and carbon cover, improved stationary installation and the fixed form thereof of carbon cover roller core supporting with it.
For achieving the above object, the carbon sleeve fixture mechanism that the utility model is designed, comprises roller core, is set with carbon cover on described roller core, it is characterized in that: described carbon cover two ends are provided with multiple draw-in grooves along its cross section radial direction; On described roller core, be positioned at carbon cover two ends and be also set with multi-jaw chuck, described multi-jaw chuck medial extremity is provided with multiple claws along its cross section radial direction, described multiple claw and multiple draw-in grooves are corresponding one by one sets cooperation, between described multi-jaw chuck and roller core, is connected by holding bolt radially.
As preferred version, described carbon cover two ends are respectively provided with three draw-in grooves; Accordingly, described multi-jaw chuck is thread jaw chuck.
Further, described carbon cover is along the circumferential direction mutually 120 ° with three draw-in grooves of one end and is uniformly distributed, and 60 ° of layouts misplace between the draw-in groove of different ends.
Further, described radially holding bolt head adopts spot welding to be fixedly connected with multi-jaw chuck junction.
The utility model has the advantage of: the utility model adopts this carbon sleeve fixture mechanism; installation, convenient disassembly; in with steel continuous annealing production process, avoided carbon to be enclosed within its swing radially, with the multi-jaw chuck of three claws, the end of carbon cover has been had to better provide protection, carbon overlaps not cracky; and stable; can not cause steel belt deviation, can improve template and the surface quality of annealing steel band, and carbon cover and roller core long service life; can enhance productivity, reduce manufacturing cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Carbon sleeve fixture mechanism shown in figure, comprises roller core 1, is set with carbon cover 2 on roller core 1, it is characterized in that: carbon overlaps 2 two ends and is provided with multiple draw-in grooves 21 along its cross section radial direction; On roller core 1, being positioned at carbon overlaps 2 two ends and is also set with multi-jaw chuck 3, multi-jaw chuck 3 medial extremitys are provided with multiple claws 31 along its cross section radial direction, multiple claws 31 and multiple draw-in grooves 21 are corresponding one by one sets cooperation, between multi-jaw chuck 3 and roller core 1, is connected by holding bolt 4 radially.
The utility model in order to solve between the snap ring and roller core of carbon cover snap ring-type locking latches, the loosening problem of roller core between overlapping with carbon, carbon is overlapped to three draw-in grooves 21 of the each processing in 2 two ends, and carbon overlaps 2 two ends and utilizes respectively two multi-jaw chucks 3 with three claws 31 to be assembled together with roller core 1.Three draw-in grooves 21 that carbon overlaps 2 two ends coordinate with the claw 31 of two multi-jaw chucks 3 respectively, and two multi-jaw chucks 3 and roller core 1 are connected by holding bolt 4 radially, then fix by spot welding.
