Abstract

PURPOSE:To execute continuous working, and to elevate productivity, by using a metallic pipe material serving as a blank material, as it remains long-sized, and working the end part of a metallic pipe by a specified pressure die, when manufacturing an I-joint which is melt-stuck to the end part of the metallic pipe. CONSTITUTION:When manufacturing an I-joint melt-stuck by a brazing metal to the end part of an oil feed pipe, an air feed pipe, etc., the tip part of a long- sized metallic pipe P serving as a blank material is held firmly by chucks 6, 6' in a state that it is projected by length of some extent. Subsequently, by a pressure die 7 provided with a recessed-shape curved surface 7', the projecting end part of the base material metallic pipe P is pressed in the axial core direction, the vicinity of a tip port circumferential part 2 is curved to the inside, and a narrowed port 4 having a flat bearing surface 3 is constituted. Also, the pipe material P side is fed out slightly forward by synchronizing with retreat of the pressure die 7, and successively, a brazing metal melt-sticking connecting hole 5 to a branch pipe or a pipe body is pierced on the circumferential side wall part, and it is cut. Subsequently, this process is repeated, and from a long-sized metallic pipe blank material, an I-jont is continuously manufactured with excellent productivity.

By performing a compression process in the t-axis direction, the circumferential side wall portion is bulged outward as shown in the figure, and both end openings are bent inward, and flat parallel seating surfaces 1 are formed on both sides.
A connecting hole 1 for solder welding is formed on the circumferential wall portion which is formed with narrow openings 14 and 14' having a diameter of 3.13' and then bulged out.
The main body 11 was constructed by penetrating the main body 11.

著しく生産性の低下を招く結果となった。However, in the method of manufacturing individual metal tube pieces cut to the required length in advance in their t-states, the individual metal tube pieces are attached to each other during the actual pressing process. Because it has to be inserted between the holes and taken out after the compression process, it causes various types of work troubles.
This resulted in a significant drop in productivity.

するものである。The object of the present invention is to solve the above-mentioned major problem by using a long metal pipe material as a 4IK material, and at the same time, by curving inward only in the vicinity of one tip orifice, a narrow opening having a flat seating surface. By providing a manufacturing method for eye joints that is very effectively solved by the structured shape, the manufacturing process is shown below in Figures 3 and 4, and the long metal pipe material P as a material can be Chuck 6 near the end opening circumference 2.
6' and set the tip with a specified length. In this state, the pressing mold 7 having a concave curved surface 7' set coaxially from the outer top part
A narrow squeeze mouth 4 having a flat seating surface 3 is formed by pressing in the axial direction to curve the vicinity of the tip opening circumference 2 inward. Furthermore, in synchronization with the retreat of the pressing mold 7, the long metal pipe material p@ is sent out a little forward and then continuously penetrated into the peripheral wall through the connection hole 5 for koji welding with the branch pipe or piping body. and then cut it to the desired specified height to make the main body 1 (see Figure 1).
The main body 1 is constructed by constructing the connecting hole 5 in each state after being cut in this way.
