9 Claims.

This invention relates generally to bending rolls of the pinch type, and is more particularly concerned with improvements in pinch type bending rolls permitting the eifective rolling of stock of channel cross-section.

In pinch type bending rolls, the stock to be rolled or bent is passed between two pinch rolls which closely support or pinch the metal between them as it is bent. A supporting roll supports one side of the stock just ahead of the two pinch rolls, and a bending roll engages and deflects it just beyond them, causing the metal to bend at the pinch rolls. The position of the bending roll with reference to the pinch rolls of course determines the amount of bend or curvature imparted to the stock. I

The aim in such bending rolls is to confine and support the metal closely at the pinch rolls, i. e., at the point of bend, so as to effectively control the flow of the metal in such a way as to assure obtainment of the desired bend or curvature, without introducing twist or other distortions. It has heretofore been found impossible, however, to handle stock of channel cross-section in such bending rolls, particularly when the stock is composed of some of the hardened aluminum alloys, for the reason that the flanges of the channel are unsupported from their inner sides, and tend to buckle, kink, or otherwise fail at the point of the bend, i. e., at the pinch rolls, with the result that the channel twists and buckles and refuses completely to assume the desired curvature.

The primary object of the present invention is accordingly the provision, in a pinch type bending roll, of means enabling the rolling and bending of stock of channel cross-section, even when formed of materials particularly difficult to handle, such as hardened aluminum alloys.

In accordance with the invention, the bending I roll is equipped with a pair of loading rolls which engage and load the inside of the channel-shaped stock opposite the points of engagement by the pinch rolls. These loading rolls adequately support the channel from inside during the bending operation, and serve to prevent buckling and kinking of the stock, to the end that it comes from the roll with perfectly smooth curvature, and without twist.

The invention will be better understood by now referring to the following detailed description of a present illustrative embodiment thereof,

reference for this purpose being had to the accompanying drawings, in which:

Fig. 1 is an end elevation of a bending roll of the pinch type equipped with the improvements of the present invention;

Fig. la. is a detail taken on line laia of Fig. 1;

Fig. 2 is an elevation showing the opposite end of the bending roll illustrated in Fig. 1;

Fig. 3 is a longitudinal vertical section taken on line 3--3 of Fig. 1;

Fig. 3a is a detail section taken on line 3a-3 a of Fig. 3;

Fig. 4 is an enlarged detail taken from Fig. 3;

Fig. 5 is a detail section taken on line 5--5 of Fig. 4;

Fig. 6 is a View similar to Fig. 4, but showing a modification; and

Fig. '7 is a view similar to Fig. 4, but showing another modification.

For the purpose of clearly disclosing the improveme'nts provided by the present invention, we have shown in the drawings and will describe a complete bending roll of the pinch type equipped with the improvements provided by the present invention; it is to be understood, however, that this is for illustrative purposes only, and that the present invention is also adaptable to bending rolls of other design.

In the drawings, numeral ll) designates generally a main frame made up of parallel vertical side plates H and i2 connected by tie rods I2-a. Angle members l3 secured to plates Ii and I2 at the bottom provide feet adapted to engage a bench or other horizontal supporting surface.

A horizontal main drive'shaft I5 is journaled in suitable bearings in frame plates H and I2, being driven from its right hand end, as viewed in Fig. 3, from any suitable power means, not illustrated, while its opposite end projects somewhat forwardly of frame plate H, as shown. Above and in alignment with shaft l5, frame plates i! and 12 are formed with vertical guide slots it for vertically adjustable bearing blocks ii, and journaled in said blocks I1 is a pinch roll shaft IS, the latter being thus disposed above main drive shaft I5, and being usually parallel to or nearly parallel to shaft l5.

Vertical lead screws 29 disposed in frame plate guide slots it have at their lower ends reduced screw threaded portions 2| set into bearing blocks I1, and jam nuts 29a on said screw threaded portions 2! are set tightly against blocks 67 to prevent rotation of the lead screws aft-er they have been adjusted. The lead screws 28 extend upwardly through housings 22 mounted on the tops of the frame plates H and I2. These housings 22 confine worm wheels 23, which surround and have screw threaded engagement with the lead screws 25. Meshing with worm wheels 23 are worms 24, which are contained within housings 22 and are mounted on a horizontal shaft 25 having on one end a crank 26, the shaft 25 being journaled in housings 22 in any suitable manner.

shaft I5 by any suitable gear arrangement per-' mitting vertical adjustment of shaft It with reference to shaft I 5, a gear arrangement permitting such adjustment is designated at in the drawings. This gear arrangement includes a spur gear 3I keyed on drive shaft I5, a spur gear 32 keyed on shaft I8, an idler gear 33 meshing with and driven by gear 3!, and another idler gear 34 meshing with idler gear 33 and also with gear 32 (see Fig. 2). Idler gear 33 is carried by a shaft 35 mounted in arms 36 positioned on opposite sides of gears 3I and 33 and provided at their one ends with circular openings 31 which rotatably receive bushings 38 on drive shaft I5. A clamp screw passing through the other or swinging ends of said arms 36 projects through an arcuate slot 4| in frame plate I2, a suitable washer 42 being placed on said screw between frame plate I2 and the arm 35 adjacent thereto. and a clamp nut 43 on the portion of screw 43 that projects through the slot 4| being set up against plate I2 to clamp the arms 36 in any position of angular adjustment. Shaft 45 carrying gear 34 is supported in the forward ends of a pair 7 of swinging arms 46, the rearward ends of which have openings 41 passing shaft I8 and receiving co-axial bosses 48 formed on the two sides of gear 32 (see Fig. 3), while the two shafts 35 and 45 are connected by links 49 which serve to hold. the gears 33 and 34 in mesh. It will be evident that, clamp screw 4!! being loosened, pinch shaft I8 and its gear 32 may be vertically adjusted without interfering with the mesh of the gears 3|, 33, 34 and 32, the arms 35 and 45 simply swinging somewhat and the several gears rolling slightly on one another as the adjustment is made.

A bending roll shaft 53, arranged parallel to and to one side of drive shaft I5; is journaled at its two ends in a pair of journal blocks 5! which are slidably mounted in guide ways 52 (see Fig. l) in the two arms 53 of a swinging bending roll 'carriage, generally designated by numeral 53.

This carriage 54, which also includes a cross-bar 60 connecting the outer ends of arms 53, is received in the space between the two end plates II and I2 of the main frame, and the inner ends of its two arms 53 have perforations 55 receiving suitable bushings surrounding drive shaft I5.

The shaft I 5 thus rotates within, and at the same timesupports, the arms 53 of carriage 54, while the latter is capable of angular adjustment about the axis of shaft I5. The carriage 54 may be set in any position of angular adjustment by means of a suitable clamp screw 56 passing through an arcuate slot 51 in frame plate I I and threaded into a lug 58 formed on the adjacent carriage arm 53. It will now be clear that movement of journal blocks 5| along slots 52 in arms 53 of the carriage 54 will adjust the spacing of shaft 50 carried by said blocks with reference to drive shaft I 5, and also, that angular adjustment of the carriage 54 by swinging movement thereof about shaft I5 will adjust the elevation of shaft 50 with reference to shaft I 5.

There remains for description suitable means by which these adjustments may be made. Movement of journal blocks 5I along slots 52 is accomplished by means of screws 59 having screw threaded engagement with the cross-bar 65 of carriage 54, and carrying the blocks 5| at their ends, the screws being turned by means of cranks 59a. The cross bar 60 of carriage 54 carries bearings SI for the two end portions of a horizontal shaft 62, the extremities of which project beyond said bearings and carry spur gears 53 in mesh with arcuate rack gears 64 which are concentric with the pivot axis of the carriage 54, and which are mounted on the two frame plates II and I2. Cross bar 65 also carries, midway between its two arms 53, a mounting 65 for a shaft 3i carrying a Worm 68 meshing with a worm wheel 59 fast on shaft 62. Clamp screw 55 being loosened, rotation of shaft 67, as by means'of manual crank tfa, effects rotation of shaft 62 through wormwheel I59 and worm 68, and therefore rotation of spur gears 53 with resulting translation of the latter along rack 64, thereby effecting angular adjustment of carriage 54 about the axis of main drive shaft I5.

Drive shaft I5 and bending roll shaft 55 are drivingly interconnected by a suitable means which will permit the described adjustments of carriage 54 and of shaft 50 to be made. A sprocket I0 tightly mounted on drive shaft I5 is connected by chain II with a sprocket I2 which is relatively rotatable on an intermediate shaft 73, and the sprocket I2 is fast with another sprocket I4, also relatively rotatable on shaft I3, and connected by chain 15 with a sprocket f5 fast on the shaft 50.

Shafts I5 and I3 are spaced by means of a pair of connecting links BI], and shafts l3 and 55 by means of a pair of connecting links 3I, shafts I5'and 511 being relatively rotatable within the ends of the respective arms and 8I. Shaft 53 is thus driven through chains 'II and I5 from main drive shaft I 5, and it will be understood that the described driving interconnection between said shafts permits the shaft 53 to be adjusted toward and from the shaft I5, as well as the angular position of the carriage to be adjusted, the angle between the connecting arms 8!] and 8| increasing or decreasing in accordance The end of bending roll shaft 53 corresponding to frame plate I I projects through a frame opening in the latter and carries at its end, outside of plate 'I I a usual bending roll 35, the latter being understood to be in the usual form of a cylinder or disc, having a Width dimension, parallel to shaft 53, adequate to engage and support the full Width of the stock S to be engaged thereby. On the opposite side ofdrive shaft I5 from the bending roll 86 is an initial supporting roll 87, which is rotatably mounted on a suitable mandrel 88 secured to frame plate I I by means of a clamp screw 89 passing through a slot 89' in plate II, the slot 89 permitting'vertical adjustment of roll El,

as will be understood. This roll 81 is also generally cylindrical in form, and of a width adequate to engage the full width of stock S. It will be understood that the two rolls 8'! and 86 are in alignment, one behind the other, and are of comparable width, so that the stock engaging and traveling over the cylindrical periphery of initial roll 8'! will subsequently engage and travel over the cylindrical periphery of bending roll 86.

Keyed on the portion of drive shaft I5 projecting beyond frame plate I I are three flat discs 9i], 9! and 92, of progressively increasing diameters, and keyed on the corresponding portion of shaft it are three similar discs 93, 94 and 95, said discs being placed in face to face contact, and being confined on their respective shaftsby means of washers 96 and screws 91 threaded into the ends of the shafts. The inside rolls 9d and 93 are spacers, the intermediate rolls 9i and 9d are the pinch rolls, which are adjusted by means of the vertically adjustable shaft I8 to firmly engage the lateral edges or surfaces of the stock to be rolled, and the outside rolls 92 and 95 serve to back up and confine the back or outside surface of the stock. driven by power rotation of drive shaft I5, the stock passes first over the initial supporting roll then between the pinch rolls er and at, and finally over the bending roll 85, the position of which determines the curvature which will be imparted to the stock, though the actual bending occurs between the pinch rolls. In the example of Figs. 3 and 4, the stock is a channel. member having web Illil, flanges Iii I and inwardly turned flange portions I92. Asillustrated, the flanges MI are engaged by the peripheries of pinch rolls ii and 534, while the web I!!!) is backed up by the larger diameter rolls 92 and 95.

Now, without support from inside the channel, it is practically impossible to impart a smooth curvature to such a channel member, particularly when the channel is composed of certain materials such as hardened aluminum alloys. Accordingly, the present invention provides means for loading the channel from the inside, whereby the flanges IIiI are maintained in firm contact with the peripheries of the pinch rolls 9! and 94. This end is accomplished by the provision of a pair of small, cylindrical loading rolls I54 and 5 i155, rotatably mounted on parallel studs i GB pro- ,iecting from a carrier block it? positioned adjacent the flange portions Hi2, said rolls being re-- ceived inside the channel and arranged so as to engage and support the edges of the flange portions B92, in the manner clearly illustrated in Figs. 3 and l. The front face of the loading roll carrier block It'I will be seen in Figs. 3 and 4 to be located between the spacer rolls 9E and 93, and to overlap and be confined by portions of the pinch rolls SI and 94. The rearward portion of the block It? is received and is vertically slidable within a vertical guide groove IIEl formed in the adjacent face of a guide plate III, positioned between the spacer rolls 9!] and 93 and collars I I2 and IIS fastened on the shafts I5 and I8, respectively. As illustrated, the lower portion of plate ii i has a bushed opening H5 which passes drive shaft i5, and has a vertical slot IIt passing the vertically adjustable shaft I8. The plate III is thus carried by drive shaft I5, which is rotatable within its lower portion, and is supported in upright position by shaft IS. The loading roll carrier block thus floats vertically on plate III,

The pinch and bending rolls being ill permitting it to conform to any irregularities on the surfaces of the channel shaped stock S.

Fig. 6 shows a modification designed to accommodate a channel member without the inwardly bent flange portions Ill-2 of Fig. i; in other words, the channel in Fig. 6 has merely the usual web I28 and side flanges I2I. In this instance, the loading rolls lii ia are arranged to engage the full inside surfaces of the flanges ii I, being mounted on studs I22 supported by a carrier block I23, which floats vertically on plate I! I, as before, all as clearly illustrated in Fig. 6. The loading rolls IMa thus engage and load the full inside surfaces of the flanges I2 I.

Fig. 7 shows another modification, illustrating the use of loading rollers for stock of I-beam cross-section, which may be treated, in eiiect, as the equivalent of two channel members back to back. The set-up here is in general the same as before, but with the exception that the pinch rolls 9i and 94 are replaced by the widened pinch rolls QIa and (Mia matching the width of the flanges I35) of the I-beam, and the rolls 92 and B5 are removed and their place occupied by a second loading roll carrier block and guide plate assem bly. Thus, the guide plate liI supports block I3! carrying studs I32 bearing cylindrical loading rolls I33 entering in the channel on the one side of the I-beam member and supporting the flanges on that side, as illustrated. And a second guide plate I 35, which may be exactly similar to the plate III, is supported on the extremities of the shafts I5 and I 8 by the washers 9t and screws 91, being provided with a vertical guide slot I38 receiving and guiding carrier block it! from which project studs I33 bearing cylindrical load ing rolls I39 entering into the channel on the other side of the I-beam and supporting the flanges on that side, all as clearly illustrated in Fig. 7. It will of course be understood that the guide plate I35 is rotatably supported by the shaft I5, and that the vertical slot It!) formed in its upper portion passes shaft I8, all in a manner similar to the corresponding arrangements for the first-described guide plate HI. Thus by this means stock of I-beam cross-section may be effectively loaded from inside the flanges of its channel formations.

The described loading rolls adequately support the channel members from inside their flanges at the point of bend of the metal, serving to control the metal as it bends, and preventing it from giving way, buckling, kinking, or twisting. To aid in eliminating all tendency to twist, the shaft carrying the upper pinch roll is sometimes tilted to a very slight angle, thus causing the flanges of the channel to be pinched somewhat more tightly at one edge than the other. By so pinching the flange at one edge, its thickness is slightly reduced at that edge, the displaced metal tending to flow longitudinally of the channel member, and by this means the flange may be caused to bend or twist somewhat toward the other edge. Proper adjustment of this pinching action on the flanges enables complete correction of 0x compensation for any tendency to twist, provided, of course, the loading rolls are employed to support the flanges from inside. As an alternative to adjustment of the angle of the upper pinch roll shaft, the pinch rolls may be made with a very slight taper, and a roll of proper taper selected for each job to be handled. In-

asmuch as the taper to be employed will be very slight, no attempt to illustrate such taper is made in the drawings.

We have now described and illustrated certain specific means by which the invention may be carried into practical efiect. It is to be understood, however, that this is for illustrative purposes only, and that various changes in design, structure and arrangement may be made without departing from the spirit and scope of the invention or of the appended claims.
