10 Claims.
The invention relates to a pipe flanging machine designed for fastening flanges to pipe or tubing by making the joint between the tubing and the flange tight against pressures to which it may be subjected while` in service.
An object of the invention is to provide a support for the peening hammer having improved mounting means adjustably mounting the hammer so that the same can be variably positioned with respect to the work piece.
A further object is to provide a support for a section of pipe or tubing which will include power means for rotating the tubing while positioning the same in the proper plane for the peening hammer.
With these and various other objects in View, the invention may `consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto.
In the drawings which illustrate an embodi ment of the device and wherein like reference characters are used to designate like parts Figure 1 is a plan View vof the pipe flanging machine embodying the features of the present invention;
Figure 2 is an elevational view of the machine shown in Figure 1 and showing the peening hammer in operative position with respect to a section of pipe supported on the rotating device;
Figure 3 is a sectional view taken along line 33:-31 of Figure 1;
Figure 4 is an end elevational view of the supporting frame for the peening hammer, the hammer being omitted in order to clearly illustrate the features of construction;
Figure 5 is an end elevational View of the supporting means for the pipe; and
Figure 6 is a detail sectional view showing the means for deforming the end of the pipe in order to securely fasten the flange thereto.
Referring more particularly to the drawings, the pipe iianging machine is mounted upon a base member 10 andincludes supporting means for the section of pipe 11 and a supporting frame 12 for the peening hammer 13. The supporting frame, as shown in Figure 4, consists of spaced side members 14 having flanged base portions 15 by means of which they are securely bolted to the base 10, and a guide member 16 forming the supporting means proper for the peening hammer `13. Arcuate slots 17, provided on the upper end of the guide members 14, receive the journals 18 of the guide member 16 and thus adjustably position the guide member within the side frames. Pivotally secured to flanges 20, projecting from the guide member, is a threaded actuating rod 21, the threaded end of which is received in the adjusting gear 22 mounted for rotation in bracket 1932, Serial No. 631,265
23 secured by bolts 24 within the frame members. Meshing with gear 22 is a gear 25 also mounted for rotation in the arm of bracket 23 and being secured to shaft 26 extending through one of the members 14, and having secured thereto the handle 27. Through the adjustable mounting of the guide member 16 the peening hammer is supported by the frame 12 in a manner whereby the same can be positioned to present its axis of thrust at the most advantageous angle to the part of the pipe that is to be deformed and through the pivotal mounting of the guide member the hammer can be traversed in the desired vertical plane with respect to the pipe. Movement of the peening die 28 of the hammer 13 is accomplished by means of the threaded actuating rod 30; pivotally secured to clamp 31 on the hammer, the threaded end of the rod being received in the feed screw nut 32, which is suitably mounted for rotation within the side members 14 by means of the trunnion bearings 33. Keyed to the projecting end of the feed screw nut is the crank 34, rotation of which serves to rotate the nut and by reason of its threaded engagement with the rod 30 the same is caused to move inwardly or outwardly, depending on the direction of rotation.
The means for supporting the section of pipe i1 in position where the end to be deformed is properly presented to the peening hammer consists of spaced supporting units indicated in their entirety by 35, suitably secured through integral base flanges 36 to the base 10 and journalling spaced friction rollers 37. The rollers are spaced a distance depending on the size of the pipe or tubing to be supported thereon and as shown in Figure 5 engageY the periphery of the tubing at spaced points, supporting the same for substantially frictionless rotation. Additional means are provided for supporting the section of pipe intermediate the units and includes spaced members 38 journalling a friction roller 40 and being pivotally secured as at 41 to a base securing member 42. Also mounted for rotation in the spaced frame members 38 is a driving roller 43 operatively connected through a chain of gearing 44 to the drive shaft 45 of the pneumatic motor 46. Suitably connected to the motor is the hose 47 for conducting the supply of compressed air thereto, the hose including an operating valve 48 by which the operation and speed of the motor can be controlled.
For operation on pipe sections of varying size it is often necessary to alter the position of the pipe through raising or lowering of the same in order that the end to be deformed may assume its proper position with respect to the hammer. Accordingly, the present structure is provided with elevating means in the form of a vertical rod 50 having its lower end threaded in and projecting below the frame 51 which serves to connect spaced members 38 in addition to forming a support for the motor 46. Keyed to the upper end of rod 50 is a hand wheel 52 through rotation of which the projecting end of the rod may be increased or decreased to elevate or lower the frame, since it will be seen that the projecting end of the rod is in engagement with the base 10.
In operation of the pipe iianging machine described a length of pipe or tubing 11 is located for rotation on the rollers 37 carried by the units 35 and on rollers 40 and 43, the latter being rotated by motor 46, thus imparting the desired rotary movement to the pipe section. The ange 53 to be ixedly secured to the end of the pipe is iirst slipped over the end of the pipe since the nt between the parts is loose and after the same has been properly positioned thereon the peening hammer is located within the end of the pipe for contact with the metal adjacent the ange, Actuation of the peening hammer, which preferably is pneumatically operated, serves to expand the pipe into intimate contact with the flange during which operation the iiange has engagement with the thrust roller 54 in order to maintain the same in proper position on the pipe. Adjustment of the peening hammer in order to vary the angularity of the thrust exerted on the pipe is accomplished through rotation of handle 27 which serves to vary the position or" the guide member 16 within the arcuate slot 17 and also by rotation of handle 34 secured to the feed screw 32 which operatively connects with the hammer above the peening die 28 through actuating rod 30.
For the inal operation in xedly securing the ilange to the tubing a die 55 is substituted for the usual die 28 and as the same is provided with a V-shaped point the end of the tubing is turned over, forming a flange which is received within a circular recess in flange 53.
It is to be understood that I do not wish to be limited by the exact embodiment of the device shown which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
