1 Claim, 11 Drawing Figures SWEDGER APPARATUS This is a continuation of application Ser. No. 295,865, filed Oct. 10, 1972, now abandoned.
This invention relates to apparatus for enlarging the inner diameter and surface of a tubular member, and more particularly to a swedging apparatus for swedging the end of a tube of pipe which is to be mated to an adjacent tube or pipe.
In the past, there has been difficulty encountered in effectively, efficiently and expeditiously overlapping mating of a tube or pipe to an adjacent tube or pipe, such as a muffler and the tailpipe of an automobile. There are instances where the end of the tailpipe or the muffler may have dents or wrinkles therein that must be straightened out before mounting the parts together.
It is an object of this invention, therefore, to provide a swedging apparatus for effectively, efficiently, and expeditiously shaping and swedging the ends of tubular members so that they will mate properly.
And another object of this invention is to provide a swedging apparatus that is easy to operate, efficient and reliable in operational use, and which is economical to operate and maintain.
Still another object of this invention is to provide a swedging apparatus, with an adapter, for enlarging the ends of tubular members of various diameters.
And to provide a swedging apparatus which is versatile and compact for enlarging tubular members. is still another object of this invention.
Other objects and attendant advantages of this invention will become more readily apparent and understood from the following detailed specification and accompanying drawings in which:
FIG. 1 is an explosed side view of a swedger incorporating features of this invention;
FIG. 2 is a view ofa first pipe to be swedged to a second pipe:
FIG. 3 is a view of a first pipe swedged to a second P p FIG. 4 is a side elevation, partially in cross section, showing a pipe to be swedged positioned on the swedger of this invention;
FIG. 5 is an end view of the swedger and pipe of FIG.
FIG. 6 is a side elevation, partially in cross section, showing the swedger being actuated and the end of the pipe enlarged;
FIG. 7 is an end view of the swedger and enlarged pipe of FIG. 6;
FIG. 8 is a side elevation, partially in cross section, of a swedger showing an adapter ring being used (for larger diameter pipes) with the pipe positioned on the swedger;
FIG. 9 is an end view of the swedger and pipe of FIG.
FIG. 10 is a side elevation, partially in cross section, showing the swedger with the adapter ring being actuated and the end of the pipe enlarged; and
FIG. 1] is an end view of the swedger and pipe of FIG. 10.
Referring now to FIG. 1 of the drawings, there is shown generally a pneumatically hydraulically operated swedger device 10 for use in enlarging the inner diameter D of a pipe or tube 42, shown in FIG. 2, to the inner diameter D of the pipe 44 shown in FIG. 3.
This swedger device 10 consists of a frustro-conical shaped ram 12 which has a ram attaching screw 34 on one end thereof for attachment to a plunger 30 positioned in a pump housing 46. The plunger 30 is provided in the pump housing 46 for moving the ram 12 as desired.
The device 10 is provided with an air intake 22 and an air exhaust port 28. It is also provided with an air control button 24, and a ram pressure release lever 26.
A coupling housing 14 which is internally threaded at the left end is provided for attachment to the threaded exterior end of the pump housing 46. The right enlarged externally threaded end of the coupling housing 14 is closed by an internally threaded cap 18.
On the inside of the coupling housing 14 there is provided a finger assembly 16 which consists of a plurality of externally shaped frustro-conical shaped segments or fingers 38. Finger retaining springs 36 positioned at the opposite ends of the finger assembly [6 hold the segments or fingers in position.
An adapter ring 20 is also provided which has fingers or segments 40 arranged around the circumference of the ring 20. The segments or fingers 40 are maintained in position on the ring 20 by the finger retaining springs 36 located at opposite ends of the ring 20. The adapter ring 20 is used on large diameter pipe 42 as will be described subsequently.
Referring now to FIG. 4 of the drawings, there is shown an assembled swedger device 10 with all of the parts in assembled position mounted with the fingers or segments 38 in position adjacent the inner diameter of a pipe or tube 42 which is to be enlarged or swedged from an inner diameter D to an inner diameter D shown in FIGS. 2 and 3, and FIGS. 5 and 7, respec tively.
As previously mentioned, the air control button 24 controls the air flowing through the air input 22 which actuates a hydraulic pump in the swedger device 10. This causes the frustro-conical shaped ram 12 to be pushed out by the plunger 30 in the direction of the arrow 32, shown in FIG. 6, to the position shown therein.
The ram 12, when it is pushed out, engages the inner frustro-conical surface of the fingers or segments 38 (which are held in place by the springs 36) and expands them radially and uniformly. Such movements of the segments or fingers 38 enlarges the inner diameter D of the pipe of tube 42 to the inner diameter D as shown best in FIG. 6.
When the inner diameter D of the pipe or tube 42 is too large for the fingers or segments 38, the adapter ring 20 is positioned between the finger assembly 16 and the inner surface of the tube or pipe 42, as shown in FIGS. 8 and 10, to enlarge the inner diameter of the tube or pipe 42 from an inner diameter D to inner diameter D as shown in FIGS. 7 and 9 respectively.
It is to be noted that the swedger device 10 should be rotated within the pipe or tube 42 to assure that a rounded enlarged inner surface is obtained for the pipe or tube 42.
Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
What is claimed is:
1. Swedger apparatus for enlarging the inner diameter and surface of a pipe, comprising:
a tapered ram having a frustro-conical configuration;
an impulse producing device having a pump housing with hydraulic means therein, means for actuating said hydraulic means, a plunger within the pump housing and engageable at one end with said ram, said hydraulic means forcing the plunger and said ram toward the end opening of a pipe to be enlarged;
housing means attachable to said impulse producing device and housing the ram substantially therein, the housing means having an outer end portion;
cap means attachable to the outer end portion of the housing means and having a centrally disposed aperture therein; and.
expander means for engagement with the interior surface of a pipe to be enlarged, said expander means being disposed in the aperture in said cap means and having a central tapered cavity for receiving at least a portion of the ram centrally therein, the expander means including a plurality of segments of frustro-conical configuration circumferentially arranged for radial movement wherein the surface of the ram engages the inner surfaces of the segments to force said segments in a radial direction and against the inner surface of the pipe on movement of the ram in a direction coincident with the longitudinal axes of the pipe and toward the open end thereof, the segments of the expander means further having flange-like inner end portions which are disposed within the housing means and abut, on forwardly disposed surfaces of said portions, portions of the interior surface of the cap means, movement of the ram to a predetermined degree for causing radial expansion of the segments acting to cause outer perimetric portions of the flange-like inner end portions to abut against the interior surface of the outer end portion of the housing means, and an adapter ring mountable on the expander means externally of the housing means and cap means and including a plurality of segments circumferentially arranged for radial movement against the interior surface of the pipe on radial movement of the plurality of segments comprising the expander means.
