Conventionally, for example, when rotating a cutting tool held in a cutting tool holder to cut a pipe extending to the holder center entrance, depending on the chuck position of the pipe or the cutting length of the pipe, when the cutting is near completion, the pipe may break under its own weight or as a result. It was also dangerous for workers as the cutting edge of the cutting tool could be damaged.

Mounted on the machine base 1 are an annular blade odor holder 14 rotated by a rotary drive unit 7 and a hollow body 13 that rotatably holds the blade odor holder. A workpiece material, for example a pipe 10, extends through the hollow body 13 and the cutting tool holder 14. A cutting tool 15 such as a cutting tool is radially attached to the blade shell holder and is movable in the radial direction. The above configuration is completely known and therefore will not be described in detail. According to the invention, a pair of parallel guide members 2 are provided on the coupling 1.

Although one of the guide members 2 is in the form of a guide rail with a rack in the illustrated example, it may simply be a guide rod. The machine stand 1 is fixed to the floor by, for example, a bracket 12. As clearly shown in FIG. 2, inverted U-shaped holders 3A and 3B are attached to the guide member 2. Holders 3A and 3B have handles 4A and 4B.
pinion 23A'23B (2
3A only shown) are mounted, and these pinions engage the racks of the guide rail 2. As a result, handle 4A, 4
By turning B, the holders 3A and 3B move the pipe 1 above the guide part 2.
It can reciprocate in the direction of the 0 mark. Vices 5A and 5B are fixed on the holders 3A and 3B, respectively. Vice 5A, 5B
The chuck itself may be a known scroll chuck, for example. The holders 3A, 3B and therefore the vises 5A, 58 are arranged on both sides of the body 13 and the cutter holder 14 so as to sandwich them therebetween.
In this way, the pipe 101 is securely held by both vises 5A and 5B. If the pipe 10 is a long pipe, an appropriate number of pipe support rollers 16 may be provided at appropriate positions in the union. As shown in FIG. 1, the machine base 1 includes a holder 3A,
Stopper flocks 9A, 9B for 38 and springs 8A, 8B fixed to the stopper blocks are attached. As a result, when the pipe 10 is chucked, if the holders 3A and 3B respectively compress the springs 8A and 8B, tensile forces in opposite directions will be applied to both vises 5A and 5B after being chucked. become. That is, the vise 5A is pressed to the right by the compression spring 8A, and the vise 5B is pressed to the left by the compression spring 8B. Therefore, as shown in FIG. 4, as soon as the cutting of the pipe 10 is completed by the cutter 15, the cut piece 10A of the pipe 10 is pulled to the right by the vise 5A, while the remaining portion 10B of the pipe 10 is pulled to the left by the vise 5B'. Therefore, the two parts of the cut pipe are forcibly separated, so that the problems mentioned at the beginning, such as the pipe 10 breaking or the cutting tool 15 breaking, are solved. It is of course possible to use other suitable springing means, hydraulic mechanism, cam mechanism, etc. in place of the springs 8A, 8B. The idea of cutting materials while pulling them in opposite directions was unprecedented.

In order to achieve this purpose, as shown in the figure, the vices 5A and 5 are
It will be understood that the initial biasing force may be applied to at least one side of B. In addition, the unit 1 preferably has a chute 1 located below the machining section to collect chips to the outside.
1 will be provided. While rotating the cutter 15 together with the cutter holder 14, the pipe 10 is sequentially cut to a predetermined length, and at the final cutting stage, the remaining length of the pipe 10 may not straddle both vises 5A and 58. . For this purpose, another chuck device 27 for chucking the inner diameter of the pipe 10 is provided in front of the vice 5A. Chuck attachment 2
Reference numeral 7 denotes a handle 21 and a holder 20 that are configured exactly the same as the handle 4A or 4B and the holder 3A or 3B.
has. A main body 28 having a hollow cylindrical shaft 22 extending coaxially with the pipe 10 is mounted on the holder 20 . The cylindrical birch 22 has, for example, a rack (not shown) that engages a pinion 31 driven by a motor 29 in the body 28, so that it is movable in the pipe axis direction independently of the movement of the holder 20. A link mechanism 26 is provided at one end of the cylindrical birch 22.
A pressing body 25 movable in the horizontal direction is provided. The pressing body 25 is configured to be opened in the radial direction by pulling the link 24 to the right in FIG. 1, and to be contracted by pushing the link 24 to the left. The link 24 itself can be reciprocated in a piston-type manner by a hydraulic mechanism (not shown) housed in the other end 32 of the cylindrical frame 22, for example. When using the chuck device 27, turn the handle 21 to move the holder 20 to the left to an appropriate position, lock it, and press an appropriate switch button (not shown).
Then, the motor 29 is started to move only the cylindrical birch 22 further to the left, and the pressing body 25 is moved into the pipe 10 to a position where it exceeds the vise 5A.

Next, the link 24 is pulled to the right, the pressing body 25 is expanded in the radial direction, and the inner periphery of the pipe 10 is strongly stretched. As a result, the chuck device 27 chucks the pipe from the internal side instead of the vice 5B. Holder 3A, 3
Detect the position of B with a limit switch and set vices 5A, 5.

As described above, according to the present invention, when chucking a workpiece material, the material is chucked with a predetermined initial elastic force (load) in the axial direction, and as soon as the material is cut, it is cut into two pieces. Since each of the separated materials is forcibly pulled apart, there is no fear that the material will break or the cutting tool will break even if the cutting tool head continues to rotate, improving work safety.
