Abstract
The invention relates to a rolling device of cold rolling mill, which mainly comprises an upper support roller, an upper work roller, a lower work roller and a lower support roller, which are arranged in a same vertical plane, and an upper middle roller and a lower middle roller which are arranged in another vertical plane leaning to a direction opposite to the advancing direction of a first rolling length of a strip material. The rolling device is characterized in that the upper middle roller and the lower middle roller are arranged offset with respect to the upper support roller, the upper work roller, the lower work roller and the lower support roller. The surface portions of the upper middle roller and the lower middle roller are symmetrically fabricated to form a certain conical degree. The rolling device has the advantages of simple, compact and reasonable structure; convenient manufacture and improved reliability of the rolling mill due to no axial movement of the upper and the lower middle rollers; improved stability of the rolling mill due to the offset arrangement of the upper and the lower middle rollers with respect to the support rollers and the work rollers; and reduced diameter of the work rollers by adopting the middle rolls for transmission, so that the rolling device can roll ultrathin strip materials in the case of constant rolling force.
Description
Technical field
The present invention relates to a kind of roll device of cold-rolling mill, specifically the roll device on the six roller strap material cold-rolling mill working stands.
Background technology
At present, traditional HC six-roll cold mill generally all adopts six roll arranged verticals, two intermediate calender rolls can move as rightabout in the axial direction, because intermediate calender rolls will move axially, generally all adopt the working roll transmission, working roll will transmit rolling torsion, and the minimum diameter of working roll will reach about 30% of strip width, do not carrying out under the situation of intermediate annealing, it is quite difficult rolling out ultra-thin strip.Will realize moving axially of intermediate calender rolls simultaneously, adopt expensive displacement transducer and servo-control system and suitable complicated mechanical devices, to the required precision height of machined piece, processing is difficulty relatively, and the manufacturing cycle is long, the production cost height.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of roll device of cold-rolling mill is provided, can improve the stability and the reliability of milling train, under the constant situation of roll-force, can roll out ultra-thin strip.
Main solution of the present invention is achieved in that
The present invention mainly adopts top backing up roll, top working roll, bottom working roll, lower support roller to be arranged in the same vertical plane, and last intermediate calender rolls and following intermediate calender rolls are arranged in to be partial in rightabout another vertical plane of the band first rolling process direction of advance; Roller hydraulic cylinder and bending cylinder block are set between top working roll and bottom working roll, bending cylinder block is fixed on the frame, feature is to go up intermediate calender rolls and following intermediate calender rolls with respect to top backing up roll, top working roll, bottom working roll and lower support roller arranged offset, and arranged offset is apart from being L.
Described L distance is 2～6mm.
The described intermediate calender rolls of going up is provided with certain tapering with symmetrical making the in the roll surface position of following intermediate calender rolls.Described upper working rolls and lower working rolls roll surface diameter and roll surface length ratio are 1/5～1/6.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Because upper and lower intermediate calender rolls does not move axially, and is easily manufactured, can improve the reliability of milling train; Because upper and lower intermediate calender rolls assembling with respect to backing roll assembling and working roll assembling arranged offset, can improve the stability of milling train; Adopt the intermediate calender rolls transmission, can reduce the diameter of working roll, under the constant situation of roll-force, can roll out ultra-thin strip.
Description of drawings
Fig. 1 is the cross section structure figure of roll device of the present invention.
Fig. 2 is intermediate calender rolls roll surface part schematic diagram in the present invention.
Fig. 3 is intermediate calender rolls roll surface part schematic diagram under the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of top backing up roll 1, last intermediate calender rolls 2, top working roll 3, roller hydraulic cylinder 4, bending cylinder block 5, frame 6, band 7, bottom working roll 8, following intermediate calender rolls 9 and lower support roller 10 etc.The present invention mainly adopts top backing up roll 1, top working roll 3, bottom working roll 8, lower support roller 10 to be arranged in the same vertical plane, and last intermediate calender rolls 2 and following intermediate calender rolls 9 are arranged in to be partial in rightabout another vertical plane of band 7 first rolling process directions of advance; Last intermediate calender rolls 2 and following intermediate calender rolls 9 are with respect to top backing up roll 1, top working roll 3, bottom working roll 8 and lower support roller 10 arranged offset, and the arranged offset distance is L, can improve the stability of milling train; Described L distance is 2～6mm.Roller hydraulic cylinder 4 and bending cylinder block 5 are set between top working roll 3 and bottom working roll 8, and bending cylinder block 5 is fixed on the frame 6, and roller hydraulic cylinder 4 is arranged in the bending cylinder block 5.
When milling train is worked, can realize positive roller to upper working rolls and lower working rolls, improve the template of band; Intermediate calender rolls 2 does not move axially in frame 6 with following intermediate calender rolls 9 on the milling train, makes simplifying the structure of milling train, reduces difficulty of processing, improves the reliability of milling train.Be made in the roll surface position symmetry of last intermediate calender rolls 2 and following intermediate calender rolls 9 and have certain tapering, described tapering is 1: 1000～1: 2000; To change working roll and backing roll contact stress state, overcome harmful contact, the roll-bending device of cooperating roller can roll out fabulous template; Milling train adopts the intermediate calender rolls transmission, thereby the diameter of working roll can be done smallerly, the minimum diameter of working roll needs only about 20% of strip width, also be that working roll roll surface diameter and roll surface length ratio are 1/5～1/6, under the constant situation of roll-force and other condition, can roll out ultra-thin strip.
