Specification of Letters Patent.
Patented Oct. 8, 1912.
To all whom it may concern.
Be it known that, I, CHARLES Lns'rnu PARMELEE, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Upsetting Metal Plates, of which the following is a full, clear, and exact description.
This invention relates to the manufacture of so-called lock-bar pipe, that is, pipe composed of transversely curved plates haw ing thickened or upset edges connected by locking bars provided with longitudinal slots or grooves into which said edges fit and in which the same are secured by bending down the edges of the bar.
It is evident that in pipe of this character the upset edges of the plates should be uni-- form in cross section, but considerable dithculty has been experienced in obtaining the desired. uniformity, chiefly by reason of the fact that the metal of the plate is not always homogeneous, or of the same hardness throughout. The result is that when the upsetting or thickening devices (usually one or more rollers) working on the plate edge strike a hard spot the degree of thickening or upsetting is less at such point than at other points along the edge. Such plates must therefore be re-rolled or otherwise corrected at the defective point, but the retreatment necessarily involves great care and skill and materially increases the cost of the pipe. Moreover, 'the production of tapered pipe-plates, that is, plates narrower at one end than the other, for making tapered pipe, has heretofore been a troublesome operation, involving several handlings of the plate as well as great care in adj usting the plate in the machine with respect to the upsetting devices.
The present invention has therefore been devised, having for its chief objects to pro vide an efficient apparatus for producing a uniform thickening of the plates no matter to what extent one part of the plate-edge may differ from another part with respect to hardness or homogeneity, and to provide means for working tapered. plates with equal facility and accuracy.
taken on line 1-1 of Fig. 2. plan vlew. Fig. 3 is a side view. Fig. 4 is a In *arrying out the invention in the preferred manner a suitable support is provided, in or on which the plate which 1s to have its edges upset is securely mounted. The upset-ting devices, preferably including a plurality of rollers, are arranged to bear against the plate edges, and provision is made for producing relative motion between the plate and the upsetting devices longitudinally of the former, whereby the edge or edges will be progressively thickened from one end of the plate to the other. The pressure exerted on the plate edges to produce the desired thickening thereof is in excess of or at least equal to that which would be required to upset the hardest part of the edge, and hence the upsetting devices would ordinarily, upset theedge, especially the softer parts of the same, to a greater extent than desired. Such excessive action is prevented however, by suitable means in the nature of a gage, which serves to regulate the relative approach of the plate and upsetting devices, so that the latter can act on the edges to a predetermined extent only, with the-result that the effective action is substantially uniform, with the consequent production of'a substantially uniform thickening.
It will be apparent to those skilled in the art that the scheme thus briefly outlined can be embodied in apparatus of various forms.
In the annexed drawing is illustrated the form which at the present time is considered to exhibit the best. mode of applying the invention, and referring now thereto, Figure 1 is a cross section of the complete apparatus, Fig. 2 is a longitudinal section, with the platc'support and the upsetting gage removed. Fig. 5 is a detail plan view, partly in horizontal section, showing the machine working on a tapered plate. Fig. 6 is a detail view, in horizontal section, of one of the upsetting mechanisms and its associated parts. Fig. 7 is an end view of the devices shown in Fig. (3, partly in cross section on line 7. Fig. 8 is a detail plan view of a slightly modified arrangement of the upsetting mech anism. Fig. 9 is a detail plan view showing one of the upsetting gages as arranged when the machine is to work on a tapered plate. Fig. 10 is a similar view showing the gage arranged for use with an untaperedplate. Fig. 11 is a detail. view in cross section, showing the construction of lock-bar pipe, the upset plate-edges being connected by an intermediate locking bar.
The operative parts of the machine are mounted on or between suitable side frames A, A, (see Figs. 1, 2, 3 and 4) connected by upper and lower cross members B, C, and constructed and arranged to withstand considerable lateral pressure or thrust. Movable longitudinally between the side frames is a carriage, designated generally by the letter D, on which the plate E is securely clamped. On the bottom of the carriage is a pair of longitudinally extending racks F, G, in mesh with gears H, I, mounted on a transverse shaft J at the front end of the machine. This shaft is rotated by any suitable means, not shown, with the result that the carriage is caused to move between. the side frames. Mounted in the side frames are two upsetting heads, K, L, carrying suitable devices, for example the rollers M mounted with their axes vertical, arranged to bear against the edges of the pipe-plate. These heads are connected to the pistons N, O, of suitable, pressure cylinders P, Q, operated preferably by hydraulic pressure, and serving to urge said heads and upsetting rollers inwardly against the plateedges. Mounted on the plate-support or carriage are twogages or guides, R, S, arranged with their outer edges parallel with the edges of the plate, and each upsetting head is provided with anti-friction rollers T, U, bearing on said guides or gages, which latter are composed of metal hard enough to withstand without deformation the maximunrpressure exerted by the machine. As before stated, the upsetting heads are urged toward the plate-edges with a pressure greater than that necessary to upset any soft part or parts of the edges, and the natural effect would be to upset the edges unevenly. This result is prevented, however, by the upset-ting gages, which, as Will be readily understood, serve to limit the inward movement of the upsetting heads under the influence of the pressure in the cylinders fl, Q, and hence allow the upsetting rollers to act on theplate edges at any point therein, to a predetermined extent only. It will therefore be seen that no matter how the metal at the edges of the plate may vary in hardness be produced throughout.
In order to wide for working tapered plates, and p lightly varying widths whether tapered or straight, the gages R, S, are adjustable toward and from the upsetting heads and are capable of being arthe same degree of upset will ranged at an angle to the longitudinal axis of the machine, as clearly indicated in Fig. 5; and the pressure cylinders P, Q, are supported on trunnions V, WV, so that they can be swung horizontally in either direction to bring the upsetting devices into effective engagement with the edges of the plate.
The plates, with their edges thickened, for example as shown at X in Fig. 11, are curved transversely and the upset edges are inserted in the slots of suitable locking bars, such as that shown at Y, in the figure just mentioned, after which the lips or flanges of the bars are bent down firmly upon the plate edges, producing a dovetail joint and holding the plates with the utmost security. The general construction and operation of the preferred embodiment of the invention being thus briefly explained, the construction of the various parts and mechanisms specifically illustrated will be readily understood. For convenience of description the parts and mechanisms referred to will be described separately so far as practicable. The plate-support or carriage.-The racks F, Gr, are carried by a bottom plate 1, supporting the longitudinal I-beams 2, which in turn support a bed frame 3. On the latter is a pair of lE-beams 1 and two pairs of channel irons, 5, 6. Above and supported on theseis the plate-bed composed of narrow cross plates, 7, on which theplate, indicated by E, rests, and above the plate is a series of I-beams 8. The latter are carried by and below transverse members 9 at each end of the carriage, (see Figs. 1, 2, and 3), which members are provided with vertical clamping or binding rods 10 surmounted by handwheels 11 working on the threaded upper ends of the rods. The lower ends of the rods are securely fixed in the lower part of the carriage, so that screwing down the handwheels will clamp the pipeplate firmly in place. The bed-frame 3, composed of transverse channel irons 12 and a longitudinal plate 13, slides on longitudinal rails 14, 15, suitably mounted on the side frames below the upsetting heads, and on the edges of the bed-frame are longitudinal members 10, i7, bearing on rollers 18, 19, mounted in brackets on the side frames, to prevent lateral displacement of the carriage in the event of one upsetting mechanism exerting greater pressure than the other.
The upsetting gagca-These devices are in the form oftlat plates or bars, (see Figs.
'1, 9, and 10), composed of hardened steel,
and rest on shelves or brackets 20, 21, mounl ed on the outermost of the channel irons 5, 6, of the plate-carriage. The gages are provided with transverse slots 22, and through the same extend bolts 23 by which the gages are secured in adjusted position; said slots permitting the gages to be arranged at an angle to the length of the carriage, as for example in the position of the gage R in Fig. 9, to provide for working tapered pipeplates, or parallel to the carriage, as in the position of the gage R in Fig. 10, to enable straight or untapered plates to be upset. For the purpose of ready and accurate adjustment of the gages a series of adjusting screws 24 are provided. working in nuts 25 secured between the channels 5, 5, and 6, 6, and on the screws are lock-nuts 26 by which the said screws can be firmly locked in any position of adjustment so as to take part of the thrust exerted on the gages.
The upsetting hcracls.These devices are referably constructed as shown in Figs. 1 and 6, and as there illustrated each is an elongated member rectangular in plan' and provided on its face with upper and lower recesses 27, 28. The upsetting rollers M are mounted in the upper recess and in the lower is a slidingmember 2!) (Fig. 1) in which the gage rollers T, U, are journaled. This sliding member is adjusted by adjusting screws 30, working in the back of the upset-ting heads and secured in position by locknuts 31 so as to take the thrust. or reaction pressure exerted by the upsetting gage against which the said rollers hear. The upsetting heads themselves are mounted in suitable recesses 32 in the respective side :t'rames.
The pressure cylinders-fits previously stated, these cylinders are mounted on trunnions V, W, so as to swing horizontally in either direction. Each piston is provided with a piston head 33 (see Fig. (3) securely bolted thereto, and in front of the head the pressure fluid is supplied by a pipe Ill. The tluid supplied to the rear of the head by a pipe 35-see Figs. 1 and (3. are connected through a valve 36 to the main supply pipe, 37, which valve is of any suitable construction (not shown) whereby the fluid may be delivered to either end of the cylinder at will; so as to advance or retract the )iston and the u isc'ttin head as desired. The valve is also constructed to permit the (,lischarge o't fluid, through a flexible waste pipe 38. from either end of the cylinder when fluid is belng delivered to the other end. To permit the cylinders to swing on their trunnions the supply pipe 37 is in each case carried down under its cylinder and provided with a swivel joint 39 in vertical alinement with said trunnions.
e wires for planing the plate-Myra [W6- poruzor (in wlpSIiifif/ the sume ln order to have the desired uniform upset the plateedges shouldbe as straight and tree from irregularities as possible. For the purpose of trimming off any irregularities that may exist on the edges a series of planing tools 40 These two pipes is provided in conjunction with each upsetting mechanism. Each series of tools is suitably mounted in a holder 41 (see Figs. 5, (5, and 7) carried by the piston rod 42 of a small pressure cylinder 43, by which the tool-holder is moved forward and held with the cutting or planing tools in engagement with the adjacent edge of the pipe-plate; said tool holder being located at the end of the upsetting head toward which the pipe plate moves so that the planing of the edge will be effected in advance of the upsetting operation. The cylinders 43 are mounted on trunnions to swing horizontally, and being otherwise constructed and operated like the cylinders I Q, need not be further described. Below the planing tools each tool-holder is provided with a recess in which is mounted a sliding head l l carrying one or more rollers 4-5 adapted to bear on the adjacent upset-ting gage, so as to regulate the cut taken by the tools. Said sliding head is adj usted by one or more screws 45, like the screws 30 employed in conjunction with the upsetting heads.
In the case of excessively hard plates it may be desirable to have the edges hot while being upset, and for this purpose a suitable burner 46 is provided, connected with a pipe l7 conveying gas and a pipe 47 conveying air for the production of a Bunsen flame. The flame directed against the edge of the slowly moving plate, serves to heat the-edge to a temperature snllicient to etl'ect a material softening thereof or to keep up the heat of a plate already hot.
.In the modification illustrated in Fig. 8 the upsetting head L is in all respects similar to that shown in Fig. (5, except that, the planing tools, -10, are carried by the head L itself instead of in a separate holder such as 11. The pressure cylinder Q. and its adjuncts are like those described in connection with Figs. (3 and 7, and further description thereof is therefore deemed unnecessary.
it is to be understood that the details of construction herein specifically shown and described in connection with the preferred embodiment o'l' the invention may be varied widely without departure from the proper scope of the invention as defined by the appended claims.
