. 4 Claims.
This invention relates to rolling mills and, more particularly, to an improved means for adjusting the rest-bars of such mills.
Rest-bars are usually employed on both sides of a mill for supporting guides for guiding the material into and out of the mill, and usually extend from housing to housing, to which they are attached. From time to time these bars have to be adjusted, either horizontally or vertically, in
order to take care of diiferent sizes of stock or to serve both sides of the mill, or for various other reasons. Anumberof devices have been suggested and used to adjust these bars, but most of them have been impractical in that they were diflicult tooperate and proper adjustment required too much time. Also, it is often desirable to adjust the bars only horizontally and at other times only vertically, and there usuaily was only one adjusting device for adjusting both horizontally and vertically which often resulted, when adjusting the bar in one direction, in losing the adjustment in the other direction, and the bar would then have to be readjusted, thus resulting in much wasted time.
It is one of the objects of this invention to provide a means whereby rest-bars can be adjusted in a horizontal direction independently of the adjustment in the vertical direction.
It is another object of this invention to provide an improved and simple means for quicklyand easily adjusting rest-bars on rolling mills in a minimum period of time.
Various other objects and advantages of my invention will more fully appear during the course of the following specification and will be more particularly pointed out in the appended claims.
In the accompanying drawing I have shown, for the purpose of illustration, one embodiment which my invention may assume in practice.
In the drawing:
Figure 1 is a horizontal section through a rolling mill with which the improved rest-bar adjustment of my invention is incorporated;
Figure 2 is a front elevation of part of a rolling mill showing my improved rest-bar adjustment in position; and,
Figure 3 is a sectional view taken on the line.
III-HI of Figure 2.
There is shown in the a rolling mill having end-housings 2 provided with a vertically extending T-shaped slot 3 on both the front and ,rear surfaces of each of the housings,-which are adapted to receive the heads of bolts. A rest-bar 4 is disposed across the housings on both the front and rear surfaces 02 the sa e as slotted holes 5 adjacent each end thereof through which bolts 6, having nuts 'I thereon, are adapted to extend from the slots 3 of the housings to hold the bar in place.
There is positioned under each end of the rest- 5 bar a vertically adjusting wedge 8 having a slotted hole 9 through which bolts l 0', having nuts l2, are adapted to extend from the slots 3 of each of the housings to hold them in place. Each of these wedges preferably has a straight upper edge I3 10 adapted to rest against the bottom straight edges of the bar, and a bottom inclined edge I adapted to rest on a flanged shoulder l5 carried by each of the housings at the bottom end of each of the slots 3. The flanged shoulders l5 have an inclined top surface which is adapted to cooperate with the inclined edge of the surface of the wedge This inclined surface is preferably a surface integral with the shoulder and housing, or may be a wedge welded, or otherwise secured thereto.
It will be noted thatwhen the slotted wedges are bolted and locked in position and the nuts I on the bolts 6 loosened, the rest-bar can be moved either to the right or left to the desired position without a change in elevation-of the bar. Likewise, when the nuts l2 on the bolts ID are completely loosened and the nuts I on bolts it slightly loosened, the rest-bar canbe adjusted vertically by moving the wedges one way or the other to allows for horizontal adjustment independent of a vertical adjustment, which is very advantageous and a great time and trouble-saver.
While I have in this application specifically shown and described an embodiment of my invention, it will be understood that this ismerely for the purpose of illustration and description, and that various other forms may be devised within 40. the scope of the invention, as defined in the appended claims.
I claim: 1
1. In a rolling mill, a movable horizontally disposed rest-bar extending across the outer faces of the end-housing portions of said mill for supporting guiding mechanism, adjustable means for attaching the ends of said bar to each of the housing face portions for horizontal adjustment of said bar thereon, a movable plate-like wedge said wedges having an inclined lower edge which is disposed against a shoulder carried by each of the faces of said housing portions and a substantially horizontal straight upper edge which is 5 disposed against the bottom edge of said restbar for-"vertical adjustment thereof.
, 2. In a rolling mill, a movable horizontally disposed rest-bar extending across the outer faces of the end-housing portions of said mill for supporting guiding mechanism, adjustable meansfor attaching the ends of said bar to each'of said housing face portions for horizontal adjustment of said bar thereon, and a movable plate-like wedge member arranged on the face of each of said I housing portions immediately below each end of said rest-bar and having a slotted hole therein through which an adjustable bolt carried by each of said housing portions is adapted to extend to adjustably hold the said wedges thereon, each of said wedges having an inclined lower edge which is adapted to be disposed against a shoulder carried by each of the faces of said housing portions and a substantially horizontal straight upper edge which is adapted to be disposed against the bottom edge of said rest-bar for vertical adjustment thereof;
3. In a rolling mill, a movable horizontally disposed rest-bar extending across the outerfaces oi the end-housing portions of said mill for supporting guiding mechanisms, adjustable means for attaching the ends of said bar to each of said housing face portions forhorizontal adjustment of said bar thereon, and a plate-like wedge member arranged below each end of said rest-bar and 35 having a slotted hole therein through which an adjustable bolt carried by each of said housing portions is adapted to extend to adjustably hold said wedges thereon, each of said wedges having an inclined lower edge which is disposed against and adapted 'to cooperate with an inclined shoulder portion arranged on the faces of each of v said housing portions and a substantially horizontal straight upper edge which is adapted to be disposed against the bottom edge of said restbar for vertical adjustment thereof.
4. In a rolling mill having a pair of housings for supporting the rolls thereof, the outer faces of each of said housings having a vertically extending T-shaped slot arranged therein for receiving and housing the heads of bolts and a shoulder portion arranged on each of said outer faces of said housings adjacent the bottom of each of said slots, a pair of bolts movably positioned in and extending outwardly from each of said slots and said housings, a horizontal restbar having a slottedhole arranged in each end thereof, said bar disposed across said housings with one of said bolts on each of the housings extending through the slots in the barvfor horiroom a GARMAN.
