Description
Technical field
The utility model belongs to field of metallurgical machine, refers to particularly a kind of reel of uncoiler with collision prevention function.
Background technology
Necessary equipment on the thin plate production lines such as uncoiler is cold-rolling continuous annealing, slitting, horizontally cut, smooth, welding, pickling, the front end of unit intake section moves back in its company of being arranged in.Existing reel of uncoiler mainly adopts following structure, and it comprises main shaft, fanning strip, pyramid, pull bar, cambered plate and pull bar crossbeam, mostly adopts the version of crosshead axial location.Wherein, main shaft plays a part to support reel, transmission power; Be fixedly installed crosshead on the main shaft, this crosshead is embedded in the groove between fanning strip and the cambered plate; Fanning strip sloping platform face and pyramid sloping platform face are slidingly connected by dovetail groove, and pyramid is placed on the main shaft, and can move axially along main shaft, and pyramid links to each other by the pull bar crossbeam with pull bar.Its operation principle is drive pull bar crossbeam transverse shifting by pull bar, thereby drive lip cone transverse shifting to be realized the breathing of reel.Crosshead has two effects, and the first is as the axial location of drum fan-shaped plate, and during reel work, fanning strip is subjected to the axial restraint of crosshead, only can radially move, and realizes the drum-expanding function; It two is the installation location that connect sleeve, and the Main Function of branch sleeve is that the coil of strip that the supplied materials coil diameter is different is connected with the sizing reel.In cold rolled strip steel production, different according to Cold Rolled Plate Thickness, the coiler mandrel maximum gauge is respectively Φ 450mm, Φ 510mm, Φ 610mm etc.; Hot rolled plate is thicker, and the coiler mandrel maximum gauge should be Φ 610mm, Φ 762mm etc. mutually.Like this when hot rolled coil during as cold rolling raw material, the working diameter of cold rolling feed reel reel is for adapting to the hot rolled coil internal diameter, often need a spacer shell to be connected, so the reel of uncoiler crosshead of Φ 450mm, Φ 510mm coil diameter will be higher than outside barrel diameter, be exactly in order to make things convenient for the location of spacer shell in fact.Above-mentioned reel structure has been continued to use the characteristics of the small-sized reel of early stage cantilevered, and bearing capacity is little, and is simple in structure, and low cost of manufacture makes things convenient for the branch sleeve location.
Yet above-mentioned reel crosshead is because need to be as the positioner of spacer shell, therefore Design of length is longer, when not being with spacer shell work, if it is inaccurate that upper volume dolly transports the coil of strip parking spot, coil of strip will knock the reel crosshead, because coil of strip inertia is larger, crosshead will be severed, and causes unexpected equipment breakdown.
The utility model content
Technical problem to be solved in the utility model just provides a kind of reel of uncoiler with collision prevention function, can effectively solve the problem of the frequent fracture damage of reel crosshead.
For solving the problems of the technologies described above, a kind of reel of uncoiler with collision prevention function that the utility model provides comprises main shaft, fanning strip, pyramid, pull bar, cambered plate and pull bar crossbeam; Described fanning strip sloping platform face and pyramid sloping platform face are slidingly connected by dovetail groove, and pyramid is placed on the main shaft, and described pyramid links to each other by the pull bar crossbeam with pull bar; Described fanning strip front end is connected with cambered plate, fanning strip and cambered plate are bolted to connection, be provided with the cambered plate groove between fanning strip and the cambered plate, be fixedly installed crosshead on the described main shaft, crosshead is embedded in the cambered plate groove, it is characterized in that: the distance of described crosshead outer end and main shaft outer is less than or equal to the minimum range of fanning strip outer and main shaft outer.
In the technique scheme, the distance of described crosshead outer end and main shaft outer equals the minimum range of fanning strip outer and main shaft outer.
In the technique scheme, described reel axle head is provided with outer support.
The beneficial effects of the utility model are: because the distance of crosshead outer end and main shaft outer is set to the minimum range less than or equal to fanning strip outer and main shaft outer; therefore under the prerequisite that does not affect its axial location; so that be reduced in the crosshead in the cambered plate groove; thereby make it to have obtained effective protection; no matter whether upper volume dolly transports the coil of strip parking spot accurate; coil of strip all can't strike crosshead; effectively avoided crosshead to be damaged; greatly improve safety in utilization and the stability of roll device, effectively reduced maintenance cost.

The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
As shown in Figures 1 to 4, a kind of reel of uncoiler with collision prevention function of the present utility model comprises main shaft 1, fanning strip 2, pyramid 3, pull bar 4, cambered plate 5 and pull bar crossbeam 6.Fanning strip 2 sloping platform faces and pyramid 3 sloping platform faces are slidingly connected by dovetail groove, and pyramid 3 is placed on the main shaft 1, and pyramid 3 links to each other by pull bar crossbeam 6 with pull bar 4.Fanning strip 3 front ends are connected with cambered plate 5, and fanning strip 3 is fixedly connected with by bolt 9 with cambered plate 5, are provided with cambered plate groove 5-1 between fanning strip 3 and the cambered plate 5, are fixedly installed crosshead 10 on the main shaft 1, and crosshead 10 is embedded in the cambered plate groove 5-1.The distance of crosshead 10 outer ends and main shaft 1 outer is less than or equal to the minimum range of fanning strip 2 outers and main shaft 1 outer.When reel is reduced to hour, namely pyramid 3 is positioned at rearmost end, this moment fanning strip 2 outers with main shaft 1 outer between the distance minimum, so the distance of crosshead 10 outer ends and main shaft 1 outer is less than or equal to above-mentioned distance.
For when protection crosshead 10 is not impacted; the tilting moment that guarantees crosshead 10 is maximum; avoid it because damaging because of stressed when reel collapses, the distance of preferred crosshead 10 outer ends and main shaft 1 outer equals the minimum range of fanning strip 2 outers and main shaft 1 outer.
Operation principle of the present utility model is as follows:
During reel work, pull bar 4 drives pull bar crossbeam 6 promotion pyramids 3 and is moved to the left, fanning strip 2 is subjected to the axial restraint of crosshead 10 fixing on the main shaft 1, radially outwards mobile under the fanning strip 2 sloping platform faces that cooperatively interact and pyramid 3 sloping platform face effects, the swollen footpath of reel, the uncoiler supporting steel coils launches steel band; Otherwise pull bar 4 drives pull bar crossbeam 6 promotion pyramids 3 and moves right, drum collapsing, and uncoiler presents volume state.
Core of the present utility model is that the distance of crosshead 10 outer ends and main shaft 1 outer is set to the minimum range less than or equal to fanning strip 2 outers and main shaft 1 outer; to guarantee that crosshead 10 is positioned at the cambered plate groove in reel work always, can be effectively protected.So its protection domain is not limited to above-described embodiment.Obviously, those skilled in the art can carry out various changes and distortion to the utility model and not break away from scope and spirit of the present utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and is out of shape interior.
