除去を行なっていた。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field 2> The present invention relates to a device for cutting and removing protrusions inside a tubular body. O is suitable for use in cutting and removing internal beads in pipes. <Prior art> In a tubular body made by forming a flat plate into a cylindrical shape and welding the mating surfaces, it is necessary to remove the weld bead, which is a protrusion. . For example, when manufacturing so-called electric resistance welded tubes in which a flat plate is gradually formed into a cylindrical shape while running and the mating surfaces are resistance welded, weld beads build up on the inner and outer surfaces of the tube and must be removed before the product can be manufactured. Therefore, in order to remove this swelling of the weld bead, conventionally, as shown in FIG. The weld bead 2 was cut and removed using a planar method. Further, as shown in FIG. 3, a rotatable rotary cutter 4 is applied to the weld bead 2 of the ERW pipe 1 running in the pipe making equipment, and the weld bead 2 is cut by the rotary cutter 4 which rotates due to the component force of the cutting resistance. I was doing some cutting and deletion.

でいる。<Problems to be Solved by the Invention> In the case of the above-mentioned type, as shown in FIG. 2, the cutting edge of the blade 3 is constantly in a red-hot state during welding and cutting, so the blade 3 wears quickly and the conversion cycle is shortened. It's quite short. Therefore, it takes a lot of time to replace the cutter 3, and if it becomes necessary to replace the cutter 3 during pipe making to remove the inner weld bead, the pipe making equipment must be temporarily stopped and the Since the blade 3 cannot be replaced without cutting into the wall, there is a drawback that work efficiency is low. Furthermore, since the cutting is continuous, the chips are discharged from the cutter in a connected manner, so that the chips on the inner surface of the tube cannot be easily discharged unless they are pulled out with a scraper or the like in a subsequent process. Therefore, manpower is always required to discharge chips, and automation of chip discharge has not been possible. Furthermore, although the rotary cutter 4 shown in FIG. 3 wears relatively slowly, it has the disadvantage that the chips are connected and become continuous.

た時を切り刃１２の交換時とする。In the device for removing protrusions inside the tubular body having the above configuration, when the formed electric resistance welded pipe 1 is sent, the drive motor 19 is driven to drive and rotate the cutter body 13, and the cutting blade 12 cuts the weld bead. Cut and remove 2. At this time, since the cutter body 13 is inclined, the weld bead 2 is cut by the entire width of the cutting blade 12 (see # in FIG. 1(d)), so uneven wear of the cutting blade 121C does not occur. Further, since the weld bead 2 is cut intermittently by a large number of cutting blades 12VC, the chips are not connected but are discontinuous. Therefore, the chip discharge process can be automated by using an air blower or the like. Immediately after cutting, the cutting portion is measured by a remaining cutting amount detection sensor 27, and based on the result, the operation of the hydraulic cylinder 25 is controlled to control the depth of cut. When replacing the cutting blade 12, the life of the cutting blade 12 should be managed by the total pressure length of the cutting length, and the cutting blade 12 should be replaced before the life of the cutting blade 12 is reached. This device is exposed when the coiled plate is removed, so the cutting blade 12
The time to replace the cutting blade 12 is when the coiled plate is finally lost before it reaches the end of its service life.

In addition, since the life of the cutting blade 12 is affected by the temperature of the weld bead 2, it is possible to change the positions of the welding point and the cutting point as appropriate, or to provide forced cooling water to the welding point and the weld bead 2. It is also possible to control the temperature of the cutting blade 12 to a desired temperature that maximizes the life of the cutting blade 12.

きる。<Effects of the Invention> According to the present invention, a large number of cutting blades are provided on the rotating outer periphery of the cutter body, and the protrusion inside the tubular body is cut and removed by driving and rotating the cutter body. The life of the blade becomes dramatically longer, and the chips become intermittent. As a result, the effort and time required for cutting blade replacement work and chip discharge work are shortened, and work efficiency can be improved.
