Description
Technical field
The present invention relates to hot continuous rolling plant equipment, particularly to the device and method that a kind of Coil Box roll coil of strip is passively transferred.
Background technology
Coil Box equipment mainly by batch station and uncoiling station form.When rolling rhythm is slower, intermediate blank forms the roll coil of strip batching station, rests on to batch unreel on station after uncoiling.When rolling rhythm is very fast, intermediate blank forms the roll coil of strip batching station, and after uncoiling, roll coil of strip head enters finishing mill F1 unit, and at this moment the roll coil of strip is transplanted on uncoiling station by roll coil of strip transfer mechanism and unreels from batching station.So will batch station to spare and continue to batch next block intermediate blank.Coil Box equipment roll coil of strip transfer both at home and abroad at present all adopts special mechanism to transfer.Its transfer mechanism huge structure, controlling complexity, weight of equipment and investment amount are big, and accident rate and maintenance cost are high.
The patent No. is the patent document disclosed " Coil Box coil of strip mandrelless transform device and method for transporting " of CN1583308A, be by by motor-driven lift roller, elect roller, float lift the lifting of roller, rotation and interoperation, and rotate each floating cradle roll between lifting, interoperation, change the position of centre of gravity of transfer coil of strip and so as to roll, thus changing the displacement of coil of strip.The method needs many group motors and lifts cooperation and the transmission of cylinder, owing to the composition of its drive apparatus is comparatively various, thus results in its control program also excessively complicated, in real production practices and inapplicable.
Coil Box equipment is not involved in rolling in hot-strip produces, and is the equipment of balanced intermediate blank temperature and insulation, and Product Precision impact is only small.Therefore, to the requirement of Coil Box it is: (1) disclosure satisfy that its basic function；(2) simple in construction, easy to operate；(3) stable, accident rate is low；(4) equipment investment and maintenance cost are low.The present invention is capable of above-mentioned requirements.
Summary of the invention
It is an object of the invention to provide the device and method that a kind of Coil Box roll coil of strip is passively transferred, adopt the technology such as Automated condtrol, friction mechanics, the knowledge of application principle of inertia, the tension force produced when roll coil of strip uncoiling occiput is entered milling train, as the power source of steel-coil transferring, dexterously by the work drawback movement of machinery, it is achieved twice boosting to coil of strip, the inertia of the recycling roll coil of strip, completes the process that the roll coil of strip is passively transferred.Being characterized in can not in use by the control program of the huge mechanism adopted in current Coil Box roll coil of strip transfer process and complexity, under the premise meeting equipment basic function, reduce weight of equipment, investment amount and maintenance cost, meet energy-conserving and environment-protective requirement simultaneously.
For achieving the above object, the present invention realizes by the following technical solutions:
The device that a kind of Coil Box roll coil of strip is passively transferred, including 1# cradle roll, finishing mill F1 unit, travelling roller, 2# cradle roll composition, 1# cradle roll is located at and is batched in station for stopping coil of strip and unreeling, travelling roller, 2# cradle roll and the 1# cradle roll A roller in 1# cradle roll are in being horizontally disposed with, the roll coil of strip from batch station transfer to uncoiling station time, it is using travelling roller and 2# cradle roll as transfer platform, after uncoiling, when roll coil of strip head enters finishing mill F1 unit, coil of strip can be produced certain tension force, the power source that this tension force is passively transferred as the roll coil of strip；Described 1# cradle roll includes 1# lifting hydraulic cylinder, 1# cradle roll A roller, 1# cradle roll B roller, fixing roller, pushes away winding up roller；1# cradle roll B roller and push away winding up roller and be separately mounted in the frame of 1# lifting hydraulic cylinder；Fixing roller, between 1# cradle roll A roller and 1# cradle roll B roller, pushes away winding up roller and is positioned at the opposite side of 1# cradle roll B roller.
When 1# cradle roll B roller is given rise to 1# cradle roll A roller same level position by 1# lifting hydraulic cylinder, the centrage of fixing roller is partial to 1# cradle roll A roller side, when its absolute altitude is on minimum diameter band Juan 1# cradle roll A roller and 1# cradle roll B roller, fixing roller does not contact with the roll coil of strip.
