JAMES HALL TAYLOR, OF OAK PARK, ILLINOIS.
PROCESS OF MAKING FORGED-STEEL PI PE-NFCKS.
Specification of Letters fatent.
Patented .ran. 12, 1915.
Application filed May 24, 1912. Serial No. 699,375.
To all whom it may concern Be it known that 1, JAMES HALL TAYLOR, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Processes of Making Forged-Steel Pipe-Necks, of which the following is a full, clear, concise, and exact description, reference-being had to the accompanying drawings, forminga part of this specification.
My invention relates to the manufacture of forged steel pipe necks such as are used for attachment to pipes of wrought metal or similar material to form a T.
It is the object of my invention to provide a simple, eflicient and eflective process and one in which there is little if any Waste of material. In present day practice, these necks are formed by primarily fashioning a billet into a stem and flange and then boring but the interior axially so as toform the neck passageway. This process s not only tedious and complicated, but it incurs the loss of considerable metal as borings and shavings. Other processes are iinvogue and these involve the use of a section of pipe to which the flange is welded or otherwise secured. These latter processes are unsatisfactory because of the joint and the desirability of an integral neck is constantly emphasized. It is with thisintegral article in view that the process first pointed out is popular. Still, as I have said, that process has its disadvantages. In my process little, if any, metal is wasted and it becomes possible to make these necks quickly and conveniently and in large numbers uniformly.
The process of my invention comprises a series of steps which cooperate to the end of producing a complete neck from a single block of wrought metal, the article of manu facture thus produced being efficient and thoroughly safe even during the great strains to which it is subjected in its use as contemplated in the art.
I have proved the practicability of my invention by actual practice and I have found that the process is productive of a thoroughly commercial article. i
The process of my invention will be best understood by illustrations showing the results of the various steps in the process.
In the accompanying drawings Figure 1 is an elevational view of the wrought metal ingot; Fig. 2 is a plan View of the blank after the first step the process has been the neck is to be formed, is-shown at a. By-
the first step in the process this billet is heated and formed, by means of dies d, d as shown in Fig. 3, into a circular body I) having a flange a at one end thereof, there being a central circular depression 6 in one end of the top and a central circular depression f in the other end of the body. This is clearly shown in Figs. 2 and 3. It will be noted that in this case there is a part 9 which remains as a web separating the two depressions and this web is punched out in order to secure the structure illustrated in Fig. 4. A mandrel m is inserted in the resulting bore in the neck and the neck is kept upon its mandrel while it is subjected to the action of the swage blocks 8, 5. These blocks are such that they do not aflect the form of the flange, but they are used to forge down the tubular part of the neck,
as illustrated in Figs. 5 and 6, drawing thev tubular part down to uniform cross-section and thus lengthening it materially as illustrated in Figs. 6 and 7. This may also press down the tubular part to a uniform diameter although this is not. necessary. The finished product, shown at Fig. 7, is seen to comprise the tubular part b and the flange c. The free end of the part b, as is well known in the art, may be spread out and.
welded in an opening in the side of a pipe while the part a may be used "for connection to a cooperating pipe nozzle or other article.
It can be seen that by employing my process for stamping out the roughly formed block, as shown in Fig. 3, there is a refinement of the metal along the walls 6 and f, as well as on the outer walls and that this refinement of the metal is not disturbed by punching out the web 9, as would be the case ifthe block were punched for its complete length. Due to the tapering of the walls, there is no disturbance of the metal along the walls e and 7 when the web 9 is punched out, as there is ample clearance for .the punching. The subsequent treatment of swaging refines the metal along the cut surface and, inasmuch as this is the thickest portion of the blank, it receives a greater treatment to compensate for the punching action. By the above, I provide a process of marked efiiciency and of great usefulness.
I claim as new and desire to secure by Letters Patent:
1. The process of forming a pipe neck from a prismatic block of metal, which consists of stamping the block to form a flange on one end thereofand to form an axial conical depression in each end thereof, whereby the surface of the walls of the block is subjected to a refining action, then punching out the metal between said axial depressions without disturbing said walls, and finally swaging the body of the block to draw the same to substantially uniform thickness.
2. In the process of forming a pipe neck from a block of metal, stamping the block to form a flange on one end thereof and to form a conical axial depression therein,
