Description
Technical field
The utility model relates to sheet metal strip and manufactures field, is specifically related to a kind of for capturing the device of sheet metal strip.
Technical background
In the preparation process of sheet metal strip, normally by being ejected in the molten steel of molten state on the chill roll of High Rotation Speed, because chill roll has low temperature, so molten steel contacts cooling formation sheet metal strip after this chill roll.Band after moulding is docile and obedient in chill roll surface, through peeling off mouth, the docile and obedient band in chill roll surface is blown and is peeled off.Band after peeling off need to be captured and be batched again, and because the thickness of band is less, be very easy to twist and rupture, therefore, how under the impaired prerequisite of band, realizing the efficient crawl of band and batch avoiding, is the focus that those skilled in the art pay close attention to.
In prior art, negative-pressure adsorption method is a kind of conventional band crawl technology, carry out as Chinese patent literature CN88202294U discloses a kind of devices for taking-up that uses the technique that metal sheet band batches, the devices for taking-up in this patent specifically comprises winding wheel, winding wheel adjusting driver, air exhauster and connects the air draft pipe of winding wheel with described air exhauster; Wherein, winding wheel is circular cavity housing, is provided with 6-16 rectangular opening in the circumferential plane of described winding wheel.Coiling technique described in this technology is: open described air exhauster, make winding wheel surface produce a certain amount of negative pressure by described air draft pipe, the negative pressure of each rectangular opening must be greater than 250mm water column; Thereby sheet metal strip is adsorbed on surface by winding wheel and batches from cooling Kun dishes out.
Above-mentioned negative-pressure adsorption technology of the prior art, when the winding wheel surface at High Rotation Speed can correspondingly produce one deck high velocity air layer, due to the existence of this layer of high velocity air, when described winding wheel is during near described chill roll, described band can be blown away, make sheet metal strip be difficult for being attracted on winding wheel, the success rate that causes band to capture is very low.And, if increase the negative pressure on winding wheel surface in order to improve the success rate of band crawl, can cause again each through hole negative pressure on winding wheel surface larger, make band easily twist and rupture in the process capturing.Therefore, how to explore a kind of crawl success rate that can either improve band, the grabbing device that can avoid again band to damage, is a still unsolved difficult problem of prior art.
