Description
Technical Field
The utility model relates to a steel processing technology field specifically is a rolling device with crashproof.
Background
At present, rolling in multiple processes is required in the production process of steel. Rolling is a press working method in which a metal material is passed through a gap between a pair of rotating rolls, and the material is reduced in cross section and increased in length by compression of the rolls, and is the most common production method for producing steel.
Because raw materials are generally supplied in a coiled manner, the rolling process of the existing factory is to uncoil the purchased raw materials by an uncoiling roller to obtain continuous and flat steel, to coil the continuous and flat steel by a coiling roller, and to prevent a pair of rotating rollers from rolling between the uncoiling roller and the coiling roller.
At the aforesaid in-process of opening a book, raw and other materials are opened a book along with the decoiler roll constantly, when opening a book the raw and other materials of last round, the raw and other materials of last round can rotate because of the decoiler roll and stop, raw and other materials can not become the horizontality by the bending state, thereby the raw and other materials of last round can strike the conveying roller in the forefront, make to produce sunkenly on the conveying roller, it is long-lasting, make steel produce burr or unevenness when passing through the conveying roller surface like this, influence rolling effect, and then reduce the planarization on steel surface, the quality of steel has been reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rolling device with crashproof solves among the prior art middle unrolling roller and can strike the conveying roller when unreeling last round raw and other materials for produce sunkenly on the conveying roller, thereby influence steel quality's technical problem.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a rolling device with an anti-collision function comprises a rack, wherein two first stand columns are arranged on the rack, an opening drum is rotatably connected between the two first stand columns, a bottom plate is slidably connected onto the rack, two second stand columns are fixedly connected onto the bottom plate, a pressing drum is rotatably connected between the two second stand columns, the rotating direction of the pressing drum is opposite to that of the opening drum, the rotating speed of the opening drum is consistent with that of the pressing drum, and the surface of the pressing drum is always attached to steel on the outermost surface of the opening drum; and a motor for driving the opening drum and the pressing drum to rotate is arranged on the rack.
The principle of the utility model lies in: the coil of strip winding that will open a book is on opening the reel, and make the coil of strip bottommost and the laminating of the top of a pressfitting section of thick bamboo, then starter motor drives and opens reel and the rotation of a pressfitting section of thick bamboo, make the rotation direction of opening the reel opposite with the rotation direction of a pressfitting section of thick bamboo, open a book a section of thick bamboo at the in-process of relaxing the coil of strip, a pressfitting section of thick bamboo is owing to offset with the least significant end of coil of strip all the time, thereby can reduce frictional force, make opening a book that the coil of strip can be better, the steel of up to last round can be because swing by a wide margin, but because the existence of a pressfitting section of thick bamboo, a pressfitting section of thick bamboo only allows steel to be the horizontality through with the clearance of. At last, steel still is the clearance that the horizontal state passes through a pressfitting section of thick bamboo and the open winding drum under the effect of a pressfitting section of thick bamboo to the completion is opened a book the work, thereby makes steel can not bump the conveying roller and influence the quality of steel.
The utility model has the advantages that: 1. the friction generated when the steel coil is contacted can be reduced through the autorotation of the pressing cylinder, so that the quality of the surface of the steel is not influenced. 2. Because the in-process of opening a book the reel, the coil of strip diameter is constantly reducing, and a pressfitting section of thick bamboo rises gradually at the pivoted in-process and constantly reduces for the diameter of cooperation coil of strip to guaranteed that a pressfitting section of thick bamboo topmost laminates with the coil of strip lower extreme all the time, guaranteed that a pressfitting section of thick bamboo can restrict and support the swing of last round steel, guaranteed the quality on steel surface.
Further optimize, still be equipped with linear electric motor in the frame, linear electric motor control bottom plate slides in vertical direction. The linear motor ensures the vertical sliding of the bottom plate on the rack, thereby ensuring that the uppermost end of the pressing cylinder is always attached to the lowest end of the steel coil.
Preferably, the second upright is located inside the first upright. Because the length of the pressing cylinder is slightly smaller than that of the opening winding drum, the second upright post is positioned on the inner side of the first upright post.
Further preferably, the length of the unwinding cylinder is slightly larger than that of the pressing cylinder. The second upright post is positioned on the inner side of the first upright post, so that the sliding space of the linear motor is ensured.
Further preferably, the bottom plate rises by the distance of the thickness of the steel material every time the uncoiling drum rotates by one circle. Ensures that the uppermost end of the pressing cylinder is always attached to the lowest end of the steel coil, thereby ensuring that the pressing cylinder can limit and support the swing of the last circle of steel,
further optimization, the thickness of the steel is 3mm-5mm, the diameter of the opening drum is 200-300mm, the rotating speed of the opening drum and the pressing drum is 125.6-188.4mm/s, and the rotating speed of the linear motor is 0.6-1 mm/s.
