Description
Technical field
The present invention relates to a kind of high-speed wire double production line swinging wire separation device, it is partly single rolling line that this device is applicable to roughing, is the high-speed wire production line of two rolling lines or many rolling lines after middle milling train.
Background technology
On the wire rod production line that single line is produced, be provided with insulating roller way.English is " INSULATED ROLLER TABLE ".Be mainly used in: through the rolled piece of heating furnace heating, after dephosphorize by high pressure water (except iron scale), carry out tempering and samming and when rolling line disorderly closedown, keep the temperature of rolled piece in roller-way, avoid steel scrap.In addition, on the high-speed wire production line of producing at above-mentioned two-wire, it is also attached with a critical function, and the rolled piece exactly single line roughing mill being shut out is assigned on the rear A of milling train in two-wire (containing middle milling train), B two lines and is rolled.
In roughing district, be single rolling line, middle milling train (containing middle milling train) is that on the wire rod production line of two rolling lines, insulating roller way is between He Zhongzha district, roughing district later.The operation principle of original insulating roller way separated time is as shown in Figures 1 and 2: totally three roller-ways are arranged side by side to be divided into A line roller-way 12, B line roller-way 13 and center line roller-way, center line roller-way is aimed at roughing machine set outlet, A line roller-way 12 and B line roller-way 13 aim at respectively in A rolling line 121 and B rolling line 131 after milling train.Rolled piece 11 enters center line roller-way from roughing mill outlet, then rolled piece 11 is stirred distributed to A line roller-way 12 or B line roller-way 13 respectively by turnover.Then by A line roller-way 12 or B line roller-way 13, the rolled piece that tilting gear is distributed is sent rolled piece into milling train in two-wire (diapsid) by front and back order and is carried out follow-up rolling, completes separated time.Each roller is by separate electrical motor transmission, and it is upper that roller-way base is fixed on basis, and tilting finger 17 is driven by crank 16, power transmission shaft 15 by hydraulic cylinder.This turnover comprises tilting finger power transmission shaft 15, crank 16 and tilting finger 17, and crank 16 and tilting finger 17 are enclosed within on tilting finger power transmission shaft 15.
But what the branch means of original separated time insulating roller way adopted is to turn over steel formula structure, has following technical problem:
1, original separated time insulating roller way reduces because moving the long production efficiency that causes of complexity and action cycle.Especially turnover requires rolled piece to become inactive state from motion state and just can turn over steel, forms continuous rolling breakpoint.
Rolled piece enters after delay table, must meet two conditions and just can turn over steel: the first, and whole steel just can turn over steel separated time after must putting in place and stopping; The second, separated time roller-way, as must be without rolled piece on A line roller-way 12 or B line roller-way 13.Turn over after steel, tilting finger 17 also must can enter next steel by return.So just bring the defect of two aspects.First be production technology.Because rolled piece will just can turn over steel separated time from the speed of 1.5m/s is stopped, and accept must so just cause technique breakpoint without rolled piece on the separated time roller-way of rolled piece, rolled piece 11 will stop in minute line process.Required time is that rolled piece adds and turns over steel required time from motion state to the time stopping; Its two, be that rolled piece returns to running status from halted state and needs the time equally.For saving time, often keep running status and the speed of separated time roller-way.As a result, rolled piece is fallen separated time roller-way in utmost point labile state after turning over steel.Due to narrow field, three backplates (because expressing clearly turnover principle, Fig. 1 does not draw outside roller way protecting plate) between roller-way cannot be installed, rolled piece is often run out of outside separated time roller-way, causes heap steel.And separated time roller-way, in accepting the process of rolled piece, is subject to very big impact.Speed is faster, impacts greatlyr, and device damage is also more serious; Its three, in equipment configuration, because rolled piece 11 will stop fast from the speed of 1.5m/s, generally with roller-way, slow down and mechanical shutter is set and complete rolled piece and stop action, like this, approximately 900 ℃ of above workpiece front ends can be out of shape because of shock in the process stopping, and are unfavorable for that milling train nips.Therefore, can only crop shears be set in the outlet of separated time insulating roller way, workpiece front end crushed element is cut away.A line roller-way 12 and B line roller-way 13 all will arrange crop shears.These have all increased that equipment configuration, equipment manufacture and design, the complexity of technology controlling and process program and practical operation.
2, original separated time insulating roller way mechanism is complicated.
As mentioned above, it is arranged side by side that original separated time insulating roller way is provided with three row's roller-ways, and turnover is distributed between each roller.Conventionally, by four hydraulic cylinders, drive respectively two 30 meters of major axis, respectively drive several tilting fingers 17 by major axis.Between tilting finger and major axis, major axis, catcher, major axis fixed bearing block and major axis and hydraulic cylinder crank all need mechanical connection etc.In addition, also to manufacture and design and can shear the two-wire flying shear of controlling by single line.When meeting in A (B) line mill milling, B (A) line crop carries out simultaneously, and the middle milling train that staggers enters the steel time, reduces to greatest extent rolled piece dwell time.
3, original separated time insulating roller way mechanism's fluctuation of service and unreliable.
Because a series of mechanical fasteners of original separated time insulating roller way exist accumulated error, the distortion of tilting finger, major axis etc., wearing and tearing, and the interlocking error of detection signal etc., often cause that to turn over steel not in place and cross position, tilting finger collision deformation, roller-way and be hit and damage the equipment faults such as bearing.The debugging that tilting gear turns over steel speed is also very difficult.If tilting gear has turned over soon, rolled piece may be crossed position; If tilting gear has turned over slowly, can influence of rolled speed, and along with wearing and tearing and the equipment of machine components are deteriorated, turn over steel speed and will often adjust.Most importantly these faults can cause regular heap steel, make to produce to interrupt.
4, original separated time insulating roller way maintainability is poor.
Due to place restriction, the various functional entities of insulating roller way are all deposited in narrow space.Comprise three roller-way stay-warm cases arranged side by side, hydraulically powered and transmission mechanism, water-cooling apparatus, roller-way drive motors, complicated turnover, mechanical shutter, two-wire flying shear, lubricator etc.Maintenance and troubleshooting be difficulty very, length consuming time.
Summary of the invention
