Referring to Figures 1 to 7 the operational relationship of the present invention configured as described above is as follows.

When the plurality of holes 4 are to be drilled in the longitudinal direction on both sides of the pipe 3 using the present invention, first, the lower mold 2 is installed upward on the table 22 of the press, and the upper mold 1 ) Is installed on the lower side of the ram, which descends from the upper side of the press.

In this state, as shown in FIGS. 1 and 2, the pipe 3 to be drilled is inserted horizontally into the core rod 50 of the lower mold 2. At this time, a pipe support groove 41 having an upper portion opened in a semicircular shape is formed in the lower pipe support 40 installed at the lower end of the burr 5 and the lower mold 2. The pipe support groove 41 and the core rod are formed. When the pipe 3 is inserted into the burr 5 between the outer periphery of the 50 so that the pipe 3 can be inserted, the lower side of the outer peripheral surface of the pipe 3 is inserted into the pipe support groove 41. It will be put on.

1 and 5, the lower pipe support 40 is elastically supported means 46 is installed elastically so that the pipe 3 is inserted into the core rod 50, the length is long and heavy weight Elastic support allows the pipe 3 to be in a horizontal state.

Before the resilient support 44 of the resilient support means 46 inserts the pipe 3 into the core rod 50, it expands upward with the elasticity of the spring 43 to elastically lower the bottom of the core rod 50. When the pipe (3) is inserted, but the front end of the pipe (3) pushes the rounded upper portion of the resilient support (44), the pipe is inserted into the outside of the core rod 50 and the spring (43) is compressed and elastic The earth 44 is pushed downward to support the bottom bottom of the pipe 3 elastically.

The tip of the drill pin 11 passing through the upper flesh portion of the pipe 3 and passing through the drill pin through hole 51 in the lower portion is placed in front of the scrap generated when the pipe 3 is drilled at the tip. In such a state, the lower part of the pipe 3 is quickly passed through the lower part of the pipe thickness.

As described above, after the upper mold 1 descends to drill the pipe 3, as the ram rises, the upper mold 1 also rises together to prepare for the next drilling operation. When it rises, the pressing force which presses the upper side of the pipe 3 is released, and the elasticity of the elastic support means 46 provided in the spring 36 and the pipe lower support part 40 of the lower part of the slider 35 is the pipe 3 Is slightly raised to the upper core bar 50 is inserted to the outside.

When scraping the upper and lower flesh thickness portions of the pipe 3 as described above, the scrap 22 through the scrap discharge holes 45, 21 formed in the pipe lower support 40 and the base plate 20 to communicate with each other 22 It is discharged downward into the space formed to open), the scrap discharge holes (45, 21) is revealed that the scrap is easy to discharge only when the larger than the outer diameter of the punching pin (11).

And, as described above, when the upper mold 1 descends and drills the pipe 3, a very large impact load acts on the lower mold 2 instantaneously, as shown in FIG. While the lower part of the fitted pipe 3 and the lower part of the slider 35 to which one end of the core bar 50 is coupled are respectively supported by the springs 43 and 36, the core bar 50 and the slider The 35 can be elastically moved up and down by a predetermined height to perforate while buffering such a large load.

The core rod 50 and the slider 35 can be lowered by a predetermined height, as shown in FIGS. 1, 2, and 4, the slider 35 coupled to one end of the core rod 50 has a guide stand ( 34 and the long hole 32 in the vertical direction to the pushing plate 33 which is installed at the portion exposed to the pipe lower support 40 side while the core rod 50 coupled to the slider 35 can be guided up and down. When the core rod 50 and the slider 35 are raised and lowered momentarily, the core rod 50 can be moved up and down elastically by a predetermined height within the length range of the long hole 32.

When drilling the pipe 3 as described above, as shown in Figure 6 and 7, the burr (5) is formed in a small size of 0.5mm or less in the direction in which the punching pin 11 passes, such as The burr 5 formed in the upper hole 4 is bent to the inside of the pipe 3, and the burr 5 formed in the lower hole 4 is bent to the outside of the pipe 3.

The upper burr 5 is inserted into the drill pin through hole 51 of the core rod 50 in each of the burrs 5 formed on the upper and lower sides of the pipe 3 in this way, but the lower burr 5 When the upper mold 1 is raised as described above, the core rod 50 and the slider 35 are slightly raised upward by the spring 36 and the elastic support means 46, and thus the burrs bent downward. There will be no jams.

By the way, the upper burr 5 is inserted into the drill pin through hole 51 of the core rod 50, and the pipe 3 inserted into the outer side of the core rod 50 is caught from the outside by the attraction force. It cannot be taken out.

In this case, as shown in FIGS. 1 and 2, when the cylinder 31 installed on the base plate 20 is operated to push the pushing plate 33 provided at the front end of the cylinder rod to the front side, the front end of the pushing plate 33 is moved. The pipe (3) located in contact with the front side is forcibly pushed out.

As described above, when the pipe 3 is pushed by the force of the cylinder 31 as described above, the core rod 50 inserted into the inside of the pipe 3 is not pushed out and is in place. The upper burr (5) inserted into the (51) is fine but bent as the inlet portion of the punching pin through hole (51) is forcibly pushed out and the upper burr (5) is bent from the punch pin through hole (51). You will be deviated.

The width to push the pipe 3 as described above is the length as far as the drill pin through hole 51 and the burr avoiding part 53 on one side, and thus the burr avoiding part 53 in the drill pin through hole 51. As the pipe 3 is pushed out, the burr 5 protruding inwardly on the upper side of the pipe 3 is loosely introduced into the burrs groove 52 as shown in (b) of FIG. 6.

Then, when the pipe 3 is turned by hand by 90 degrees, the burr 5 which has entered the burrs groove 52 is chamfered (cutting) on both sides of the core rod 50 as shown in "a" shown in FIG. ) To the burr avoiding part 53 which forms a space enough for the burr 5 to be inserted.

The burr avoiding portion 53 is formed in the longitudinal direction at both sides of the core rod 50 in the longitudinal direction, so that the burr 5 descends to the burr avoiding portion 53 and is loose. If pulled out to the outside of the pipe (3) is easily pulled out to the core rod 50 without being caught.

As the pipe 3 drilled out of the core rod 50 is removed, the pipe drilling operation in the present invention is completed. Thus, the pipe 3 can produce objects such as pin jigs for ship block pedestals. It will be possible.
