Abstract
The utility model discloses sour rolling mill mandrel of uncoiler conical sleeve device, in the active side of mandrel secter pat, conical sleeve is installed, dust excluding plate and mandrel are fixed in conical sleeve stationary plane one end, conical sleeve stiff end has four in dovetail shaped end face, conical sleeve other end connection bearing, bearing connecting axle is contracted.Mandrel conical sleeve device can be changed process after solving the fracture of dust excluding plate set bolt specially in time, avoid mandrel inner prismatic tapered sleeve abnormal damage, equipment is effectively controlled, guaranteed performance is stable, also optimize the inner spot check work of mandrel simultaneously, thoroughly stop the equipment breakdown that the impact that defect causes thus is produced, be conducive to machine management and maintenance.Substantially increase operating efficiency, the equipment that ensure that normally run and structure simple, be easy to field-strip.
Description
Technical field
The utility model belongs to acid and rolls apparatus for production line, relates to the improvement of sour rolling mill uncoiler.
Background technology
Sour rolling mill uncoiler Main Function launches coil of strip to be convenient to threading, its this uncoiler is a cantilevered list mandrel 4 fan-shaped segment types, every block fanning strip is provided with one piece of dust excluding plate, the Main Function of dust excluding plate is used to prevent brown iron oxide from entering inside, due to the judder that the problems such as raw material plate shape and dust excluding plate workpiece deviation then produce, cause dust excluding plate bolt fracture, distortion card group, mandrel is caused to shrink not in place and after breaking down, do not have reliable treatment measures, cause the rolling line warning shutdown processing time longer, extreme shock is brought to normal production direct motion and daily maintenance.
Utility model content
The utility model is for overcoming above technical problem, and spy is improved existing sour rolling mill uncoiler.
Technical scheme: sour rolling mill mandrel of uncoiler conical sleeve device, in the active side of mandrel secter pat, conical sleeve is installed, dust excluding plate and mandrel are fixed in conical sleeve stationary plane one end, conical sleeve stiff end has four in dovetail shaped end face, conical sleeve other end connection bearing, bearing connecting axle is contracted.
The end face of described dust excluding plate is also dovetail shaped, and two inclined-planes are with wool felt.
Beneficial effect: mandrel conical sleeve device can be changed process (the online fast of spare part is changed) in time after solving the fracture of dust excluding plate set bolt specially, avoid mandrel inner prismatic tapered sleeve abnormal damage, equipment is effectively controlled, guaranteed performance is stable, also optimize the inner spot check work of mandrel simultaneously, thoroughly stop the equipment breakdown that the impact that defect causes thus is produced, be conducive to machine management and maintenance.Realize the quick dismounting of dust excluding plate, save three steps not only proterctive equipment precision, also improve the controllability of equipment management personnel to equipment simultaneously, substantially increase operating efficiency, the equipment that ensure that normally run and structure simple, be easy to field-strip.The method for dismounting that past is loaded down with trivial details, is optimized for online plug-type Fast Installation, not only increases peace-keeping personnel to the controllability of equipment, the security performance that also saves equipment cost, save maintenance man-hours, improve equipment.

Fig. 2 is the cross-sectional schematic of conical sleeve:
Fig. 3 is that the A-A of Fig. 2 is to cross sectional view.
Detailed description of the invention
Sour rolling mill mandrel of uncoiler conical sleeve device, in the active side of mandrel secter pat, conical sleeve 3 is installed, dust excluding plate 4 and mandrel are fixed in conical sleeve 3 stationary plane one end, conical sleeve 3 stiff end has four in dovetail shaped end face, conical sleeve 3 other end connection bearing 2, bearing 2 connecting axle contracts 1.The end face of dust excluding plate 4 is also dovetail shaped, and two inclined-planes are with wool felt, anti-skidding.Conical sleeve 3 is arranged on the active side of mandrel secter pat, the appearance profile of four stiff ends of conical sleeve 3 is processed into swallowtail shape, be divided into four stationary planes to be used for fixing dust excluding plate 4 and mandrel normal contraction, expansion, dust excluding plate 4 end face is also dovetail shaped, two inclined-planes are with wool felt, overall length is: 2058mm, adopts M12mm to be bolted on active side (conical sleeve) and transmission side mandrel framework.
