METAL-ROLLING MILL.
Application filed August 2'7-y 1924. Serial No. 734,403.
At the present time it is the practice to form many articles, such as lock washers, 'f rom strips which have been cold drawn into shape usually by a plurality of drawing operations interrupted by one or more annealing operations. My invention provides new and A improved means for producing such strips.
In the drawings accompanying this speci- Iication and forming a part thereof I have shown, for purposes of illustration, one form which my invention may assume. In these drawings:
Figure 1 is a face View of the rolling section of this illustrative embodiment of my invention,
figure 2 is a similar view of the actuating section,
Figure 3 is a section on the lines 3-3 of Figures 1 and 2 showing also the mechanism connecting the rolling sectionand the actuating section, while Figure 4 is a diagrammatic illustration of a method of rolling for which this machine is particularly applicable.
The rolling mechanism herein disclosed comprises a plurality of rolls 11 formed so that the adjacent face of each roll is tangential to the circular face of the preceding roll whereby the rolls conjointly define and form the walls of an aperture through which the.
strip is passed and conjointly act upon the strip as it passes through this aperture to form the strip into a cross-section identical with that of the aperture. Each of these rolls 11 is adapted to be rot-ated by means of a shaft 12 fixedly carrying the roll 11, itself rotatably mounted in bearings 13 and 14 carried by a block 15, and itself rotated by -means of a bevel gear 16 fixed to the shaft 12 and rotated in turn by means of a cooperating bevel gear 17 carried by and fixed to a shaft 18 rotatably mounted within a bracket 2O carried b-y the block 15.
lEach of these blocks is adjustably supported from the rolling section frame 21, held in position against movement axially ofthe strip by engagement with the plate 22 overlying the front of the rolling section anda sectional plate 23 overlying the poi tion of the rear face of the rolling section orresponding to *the particular block 15, held in position against lateral movement by engagement with the parallel faces 24 of wedge members 25 and 26 cach provided with faces 27 inclined reversely relative to each other and engaging cooperating inclined faces 28 and 29 formed upon lugs 30 projecting inwardly from and integral withthe frame 21 and each comprising a stem 31 projecting through an aperture 32 in the frame 21 and screw-threaded to cooperate with a nut 33 bearing against the exterior of the frame 21 whereby the wedge may be moved inwardly by direct pressure against the stem 31 and may be forced outwardly by the rotation of the nut 33, held against movement radially from the strip by means of a pair of bolts 34 screw-threaded lthrough the frame 21 with their inner ends 35 in contact with the outer face 36 of the block 15, and held against radial movement toward the strip by means of the strip itself and a bolt 37 passing through an aperture 38 in the frame 21 and provided with a head 39 overlying the frame 21 and an inner end 40 screw-threadedly engaging the block 15.
The actuating section of the device herein disclosed comprises a pair of plates 41 and 42 held in spaced position by means of bolts 43 and collars 44 and supporting a plurality of shafts 45 each substantially 1n alinement with one of the shafts 18 of the rolling mechanism and connected to that shaft by means of an intermediate square shaft 46 secured to the squared end 47 of the shaft 18 by means of a loosely fitting sleeve 48, secured to the squared end 49 of the shaft 45 by means of a similar loosely fitting sleeve 50, and provided with a pair of collars 51 and 52 effective to hold in position the sleeves 48 and respectively. Each of these shafts 45 is operated by a pinion 53 fixed thereto and all of the pinions 53 are driven by a singlel sun gear 54 fixed to and mounted upon a shaft 55 rotatable in the plates 41 and 42, projecting beyond the rear face of the plate 42 to receive any suitable driving device such as, a sprocket, alined with the aperture between the rolls 11, and hollowto ,permit the -pas sage of the strip therethrough.
The rolling section of the device and the actuating section of the device are both secured to a common base herein shown as consisting of a pair of I-beams 57.
It will be lapparent from the above description that the strip enters through the hollow shaft 55 and then passes between the rolls 11 to be formed by these rolls into a section having the same contour as the aperture between the rolls; that the rolls may be adjusted laterally of the strip by actuation of the Wedges 25 and 26 and radially of the strip by reverse actuation of the bolts 31 on the one hand and the bolt 34 on the other hand, and that the rolls may therefore be adjusted to produce any section Within the limits of the particular machine; that the rolls are positively driven whereby the'necessity for tension upon the strip is entirely eliminated and a greater reformation of the section is possible in a single pass and Without inaccuracies in the emerging section; and that the portion of the roll operating mechanism mounted Within the rolling portion of the device moves as a unit with the rolls and therefore requires no attention upon adjustment of the rolls, the portion of the operating mechanism mounted Within the operating portion of the device is fixed and unaltered by adjustment of the rolls, and the loose engagement of the sleeves 48 and 50 permits the adjustment of the rolls Without any necessity. for adjusting the operating mechanism at any point.
It Will also be apparent that the action of the device in positively driving the strip prevents the strains due to the usual drawing of the strip through rolls actuated only by the strip itself whereby the use of a machine of the type herein described eliminates the necessity of maintaining the strip static during annealing and, on the contrary, permits annealing of the strip as part of a continuous process in which the annealing oven is interposed between adjacent rolling machines and the strip passes in a continuing action through the various rolling machines and annealing ovens, all as indicated diagrammatically in Figure 4. AIt will also be understood that While I ndit advisable, particularly for this purpose, to drive all of of the rolls, I may, under certain circumstances, find it possible to omit the drive from one or more of the rolls and may omit that lmuch of the drive to simplify the construction of the machine.v It Will also be understood that Imay utilize any number of rolls and that the likelihood of omission of the drive from onev or more rolls will increase With the number of rolls utilized. And those skilled in the art Willreadily realize that the particular machine herein y shovvn may be variously changed and modified Without departing from the spirit of my invention or sacrificing the advantages thereof and that the 'disclosure herein is illustrative only and my invention is not limited thereto.- i
