Abstract
The invention discloses a device for preventing a short stress vertical roller mill and a stand housing from being stuck by rolled foreign matter. The device comprises a seal baffle board and an elastic baffle sheet, wherein the seal baffle board is arranged in a downward sloping mode, the high end of the seal baffle board is arranged on the stand housing, and a gap is arranged between the lower end of the seal baffle board and the upper surface of a rolling mill bearing pedestal; the elastic baffle sheet is arranged between a rolling mill bearing pedestal lining plate and the rolling mill bearing pedestal, and the top edge of the elastic baffle sheet extends out of the rolling mill bearing pedestal to form sealed connection with the lower end of the seal baffle board. The device can completely prevent sharp fragments, wires and other foreign objects produced during rolling from entering, and the adjustment of the rolling mill or the replacement of rollers is ensured to be smooth and free. The device is especially applicable to a short stress vertical rolling mill of hot rolling strip steel.
Description
Technical field
The present invention relates to a kind of servicing unit of hot-strip short stress vertical roller mill, a kind of specifically short stress vertical roller mill and framework memorial archway of preventing is rolled the stuck device of foreign matter.
Background technology
The hot-strip short stress vertical roller mill is installed in the framework memorial archway; impact shock and roll change are convenient when stinging steel for minimizing; the gap also is that fit clearance generally is controlled between the 0.8-2mm between rolling mill bearing liner plate and the frame liner plate between milling train and the framework memorial archway; when rolling especially workpiece front end enter milling train after regular meeting produces a large amount of sharp-pointed fragments; rolled foreign objects such as wire drawing; in case sharp-pointed fragment or wire drawing etc. are splashed and are entered between rolling mill bearing and the frame liner plate; just can rolling mill bearing is firmly stuck; cause milling train can't adjust width; and can't release roll from framework memorial archway during roll change, seriously influenced ordinary production.
Summary of the invention
Can't adjust the problem that width maybe can't be changed roll in order to solve stuck in framework memorial archway, the causing of foreign matter of being with the steel short stress vertical roller mill to be rolled generation, the purpose of this invention is to provide a kind of short stress vertical roller mill and framework memorial archway of preventing and be rolled the stuck device of foreign matter, foreign matters such as the sharp-pointed fragment that this device can prevent to produce in the operation of rolling fully, wire drawing enter, and guarantee the milling train adjustment or change roll smooth.
The objective of the invention is to be achieved through the following technical solutions:
A kind of short stress vertical roller mill and framework memorial archway of preventing is rolled the stuck device of foreign matter, it is characterized in that: this device comprises sealing baffle and elastic block piece, the high-end of downward-sloping setting of sealing baffle and sealing baffle is arranged on the framework memorial archway, is provided with spacing between the low side of sealing baffle and rolling mill bearing upper surface; Elastic block piece is arranged between rolling mill bearing liner plate and the rolling mill bearing, and the top margin of elastic block piece stretches out behind the rolling mill bearing low side with sealing baffle and forms and be tightly connected.
Sealing baffle of the present invention is a steel plate, and elastic block piece is the good sheet brass of elastic performance.Downward-sloping 60 degree of described sealing baffle are provided with.Spacing between the low side of sealing baffle and rolling mill bearing upper surface is 30mm.
Among the present invention, the top margin of elastic block piece stretches out behind the rolling mill bearing 50mm low side with sealing baffle and forms and be tightly connected.
The present invention is provided with a downward-sloping sealing baffle on framework memorial archway, sealing baffle is higher than the rolling mill bearing certain distance, between rolling mill bearing liner plate and bearing block, add one deck elastic block piece, and make the elastic block piece top be higher than bearing block upper surface certain altitude, make the elastic block piece that adds on the downward-sloping sealing baffle and rolling mill bearing on the frame form sealing to fit clearance between frame liner plate and the rolling mill bearing liner plate, the foreign matter of guaranteeing rolling generation can not enter the fit clearance between frame liner plate and the rolling mill bearing.
Compared with prior art, adopt foreign matters such as sharp-pointed fragment that the present invention can prevent to produce in the operation of rolling fully, wire drawing to enter, guarantee the milling train adjustment or change roll smooth.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 adopts a kind of embodiment of the present invention on the strip mill short stress vertical roller mill.
The specific embodiment
A kind of short stress vertical roller mill and framework memorial archway of preventing of the present invention is rolled the stuck device of foreign matter, sees Fig. 1, and this device comprises sealing baffle 1 and elastic block piece 2, and sealing baffle 1 is a steel plate, and elastic block piece 2 is the good sheet brass of elastic performance.Sealing baffle 1 downward-sloping 60 degree are provided with and the high-end of sealing baffle 1 is arranged on the framework memorial archway 3, are provided with the 30mm spacing between the low side of sealing baffle 1 and rolling mill bearing 4 upper surfaces; Elastic block piece 2 is arranged between rolling mill bearing liner plate 5 and the rolling mill bearing 4, and the top margin of elastic block piece 2 stretches out behind the rolling mill bearing 4 and the formation of the low side of sealing baffle 1 is tightly connected.Be provided with fit clearance 7 at rolling mill bearing liner plate 5 and 6 of framework memorial archway liner plates.
The strip mill short stress vertical roller mill from coming into operation after the sharp-pointed cracked and wire drawing that often occurs producing in the operation of rolling etc. enter between milling train top chock and the framework memorial archway in the gap, very large resistance appears when causing rolling mill bearing to need adjustment or replacing often in the frame board, make rolling mill bearing stuck in framework memorial archway under the serious situation, can't adjust milling train, can't normally change roll.
Adopt the present invention, on the frame liner plate, be provided with dip down 60 ° steel baffle plate of the long 1800mm of the wide 120mm* of thick 10mm*, baffle plate is higher than milling train step upper surface 30mm, between milling train step and its liner plate, added the thick sheet brass of 0.5mm, the sheet brass top exceeds milling train step upper surface 50mm, because the sheet brass elasticity of 0.5mm is fine, when packing framework memorial archway into, milling train can be close to have a down dip 60 ° steel baffle plate lower surface of framework memorial archway, the gap of having guaranteed framework memorial archway liner plate and rolling mill bearing liner plate cooperation place is effectively sealed, the foreign matter of any rolling generation, as sharply cracked, wire drawings etc. can not enter in the fit clearance between rolling mill bearing and the framework memorial archway fully.Practice shows, after the opposite roller milling train was implemented anti-jamming device, the phenomenon of the stuck mistake of foreign matter of generation appearred being rolled in vertical miller never again.
