Compared with the prior art, by means of the straight head pinch roll device, an unbender unit and a hydraulic system which can float transversely are removed, investment is lowered, straight head operation is simple and practical, meanwhile, uneven reeling caused by camber due to the fact that pinch roll outlet strip steel vibrates is avoided, and reeling quality is improved.
Description
Technical field
The utility model relates to the fire door compression apparatus, more particularly, relates to a kind of straight peen pinch roll apparatus.
Background technology
Cold rolling finishing unit is furnished with a cover uncoiling pinch roll apparatus behind uncoiler, this device comprises frame (top pinch roll 12, bottom pinch roll, bottom pinch roll cylinder are arranged in the frame), the transmission system of bottom pinch roll, the traversing hydraulic cylinder of frame and draws the material platform, gantry base is equipped with roller or linear guides, and the CPC photoelectric detection system is installed in pinch rolls outlet frame top.
Behind volume on the coil of strip, to take the lead to enter pinch roll by drawing the material platform, the band operation is worn in " uncoiler-pinch roll " interlock forward.In order to make after the uncoiling band steel wear band smoothly, need be to band steel straight peen, both five roller coil openers by uncoiling pinch roll back made and take the lead to upwarp slightly.In the crossing process, take the lead to enter circle shear smoothly like this, can not pierce between carrying roller and guide plate the slit or be stuck in that hydraulic pressure is horizontally cut, in the oiler.
Existing five roller coil opener primary structures comprise frame, smoothing roll, transmission device etc., when operation, the uncoiling pinch roll is opened, under the control of CPC photoelectric detection system, move centering with the uncoiler synchronous horizontal, to guarantee that band steel center line and circle shear center line are consistent, and obtain satisfactory width dimensions.
In actual use, there is following problem:
1, the outlet band steel of floating type uncoiling pinch roll rocks seriously.
Because the outlet band steel transverse shakiness of floating type uncoiling pinch roll is obvious, make to produce the camber defective in the circle shear shear history, the camber defective will influence EPC function precision, causes to batch unevenly, and unfitness of butt joint exceeds standard, and then influences reeling quality.
2, five roller coil opener cost performances are not high, and adjust complicated.
Because five roller coil openers are types of flat shape roller straightener, two upper straightening rolls are regulated by handwheel and are undertaken by worm-and-wheel gear, which is provided with fast and open, by Driven by Hydraulic Cylinder lifting in the window of frame.Below three rollers fixing by two, exporting a smoothing roll can carry out up-down adjustment by worm-and-wheel gear.
And, five roller coil openers at first will make up up-down rollers hold together when using, if take the lead perk or down button just can't pass through five roller coil openers, and its effect can not be satisfied production board shape precision, so be a kind of auxiliary equipment of being convenient to wear band only for taking the lead of obtaining to upwarp slightly, yet its complicated electrical equipment transmission control, hydraulic operation mechanism, drafts controlling organization, determined its high cost, so contrast is bigger between investment and the actual use, cost performance is low.
Because the quality of straight peen effect depends on whether top roll is that the drafts parameter is selected appropriate, and that parameter is selected is relevant with band steel specifications parameter, steel grade material, and different supplied materials needs setup parameter to be not quite similar, and uses improperly, and effect is run counter to desire.
