INCORPORATE-D, or new YORK, N. 2., .A-GORPORATION on NEW YORK ROLLING MILL GUIDE Application filed Deceinber 10, 1930. Serial No. 501,212.;
This invention relates to a rolling mill guide, and more particularly to a quick releasing guide for'rod mills.
In the operation of rod mills, it frequently happens that the rod or her being rolled becomes kinked or deformed in such a way that it will not pass the guide but will become wedged therein in such a way as to obstruct the guide. This makes it necessary to disassemble or adjust the guide to permitthe deformed portion to pass, after which the guide is restored to its normal position until another obstruction occurs.
An object of the present invention is to provide a guide which may be quickly and easily adjusted or manipulated to release the metal being process-ed. r
In general terms, the invention comprises a pair of complementary guide plates forming a guide passage for a rod, the outer cross} section of the guide plates being upwardly tapered to permit them to fit Within an upwardly tapered recess in the guide box frame.
The guide plates are normally held in their operative position by a wedge inserted beneath their lower edges, and when it is desired to release the guide plates the wedge is moved rearwardly, allowing the plates to drop by gravity. The taper of the aperture in which they are held then allows them to separate and release the rod. 7
The invention will be more fully understood from the following description, taken in connection with the accompanying drawing, in which Fig. 1 is a longitudinal sectional view of a guide embodying the invention; V
Fig. 2 is a rear elevation of the same, and
Fig. 3 is a sectional view taken along the line 33 of Fig. 1.
The guide illustrated in the drawing comprises a frame member 8 having a down wardly extending flange 10 designed to engage a cross bar12'secured to the frame of the rolling mill, the frame member 8 being adjustable by means of a bolt 14 seated in a vertical slot formed in the flange 10. The frame member comprises an upwardly extending flange 15, and a guide-carrying member 16 having a horizontally extending aperture 18. side Walls of aperture 18 are tapered upwardly, the aperture being 7 designed to receive apair of complementary guide plates 20 and 21 the outer lateral surfaces of which are' upwardly tapered to en:
able the die plates to fit within the aperture '18 when in their assembled position. The
guide plates are provided with registering grooves-24 which together form the guiding aperture 26 which is designed to lead the rod to rolls 27 of a rolling mill. The member 16 is provided with a forwardlytapering recess 28 formed therein beneath the aperture 18 and a wedge member 30 is slidably mounted Within this recess and normallyretains the guide plate 20 and 21 .in'theirjuppermost and'op'erative position.
p The guide plates 7 with rear flanges 22 and 23 which normally seat against member 16 to retain the plates in their normal position.
20 and 21 are prm rided In operation, the gu1de functions in the known manner until a deformed portion of wrench or other suitable tool rotates the bolt 32 in such a direction as to tend to thread leavesthe guide plates 20anjd 21 free to drop downwardly,but the plates will ordinarily beheld in their normal position by the. wedging action of. the materialuntil the, wedge 30. engages the flanges 22 and 23 and bears against them with sufficient force to loosen the guide plates andipermit them to drop freely downwardly, whereupon the rod may be withdrawn from the guide or allowed to pass on through the rolls. ,In the same way,
the guide platesmayif desired-beentirely I removed. To reassemble the guide, the guide plates are inserted inthe'member 16. and
. sc- X the rod enters the guide and obstructs 1t. -When this occurs, the operator by means of a forced into place by the cam action of the wedge 30.
Although the invention has been described in connection with a guide designed for use at the entrance side of the rolls, it will be apparent that it may also be used at the delivery side of the rolls. Instead of the bolt I '32, a cam or other. quick-releasingmeans may be used to withdraw the wedge and release the guide plates. Other modifications in the apparatus described may be made within the scope of the following claims.
-What is claimed is:
1. A rolling mill guide comprising a frame,
guide members longitudinally after the opening thereof upon a further movement of the tapered member. 7
In witness whereof, I hereunto subscribe my name this 28th day of November A. D.,
IRA S, NELSON.
a pair of channeled guide plates positioned 7 within and mounted forvertical movement upon said frame and cooperating to form a v guide channel, said frame being provided with an inclined surf-ace spaced from the guide plates, a wedge member interposed between the guide plates'and said surface to retain the guide plates in operative position,
and means for moving the Wedge member longitudinally of the guide plates and permit a downward movement thereof by the action r of gravity to release'the guide plates.
2. A rolling mill guide comprising a frame provided with an elongated aperture having upwardly tapering walls, separable cooperat ing guide membershaving their outer walls aperture, an incl inedsurface positioned below the guide plates and spaced therefrom, a wedge member interposed between the guide plates and said surface to retain the guide plates'in operative positiomand means for similarly tapering and fitting within said I moving the wedge member longitudinally of theguide plates to release them and to cause the wedge member to engage them and move them to an inoperative position.
3. A rolling mill guide comprising a pair of'lguide members cooperating to form a guide channel and mounted to sep-arate'laterally when permitted to move downwardly,
an inclined surface positioned below-the guide members and spaced therefrom, a wedge member mounted to travel on said inclined surface and normally bearing upwardly against the guide -menibers for retaining guide channel, a tapered member for vertically supporting the guide members in closed position and means for moving the tapered member longitudinally of the guide members to permit them to move downwardly by the action of gravity to an open position, said guide plates and tapered member'having cooperating surfaces engageable to move the
