Abstract

PURPOSE:To provide a piping processing device by which a plurality of works such as length measuring, cutting, and chamfering of thin-walled, small-diameter piping are performed. CONSTITUTION:An automatic feeder 2 for axially feeding piping, a rotation device 3 for rotating the piping, a chamfering tool 6 for chamfering, and a chuck 4 for fixing a pipe 9 piping for recovering chip are supported inside of a support base 10 and a cutting tool 5 for cutting the piping is supported outside of the support base 10. This constitution eliminates length measuring works before piping cutting and realizes cutting works with high efficiency and high accuracy. And chips generated in the last chamfering work scarcely enter the inside of the piping so that cleanness of the piping can be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting and chamfering thin-walled small-diameter pipes used in semiconductors, foodstuffs and plants.

[0002]

2. Description of the Related Art TRI TOOL, which is a typical example in our daily lives
(USA) thin wall pipe cutting groove processing machine is used for cutting and groove processing. This processing machine performs processing by fixing the pipe and rotating and automatically feeding the cutting tool.

[0003]

In the prior art, since the cutting tool is rotated while the pipe is fixed, the cutting speed in cutting / grooving is slow, and errors are likely to occur because the length of the pipe is measured and the work set is performed every time. Is bad.

Since the final groove processing is also carried out in the same manner, chips remain inside the pipe, and a lot of time is required for cleaning work after processing.

[0005]

[Means for Solving the Problems] It is assumed that cutting is performed by rotating a pipe and feeding a cutting tool, and by adopting an automatic feeding device (auto bar feed), it is possible to efficiently and accurately measure a fixed length material pipe. It shall be possible to perform repeated cutting.

The final chamfering process can also be performed by the same device. The process is performed downward, and the inside of the device has a structure capable of collecting chips, so that the cleanliness inside the pipe can be secured.

[0007]

The pipe is fed by the automatic feed device (auto bar feed) in a predetermined size, and the pipe is rotated by the rotating device and cut by the cutting tool. The chucks of the pipes of the automatic feeder and the rotating device should not be in contact with the pipes at the same time by the air cylinder. Use a rubber material as the chuck material so that the piping will not be damaged.

After cutting the pipe, the pipe is fed again by the automatic feeding device, and the cutting work is repeated. The chamfering process is performed by holding the cut pipe in hand and pressing the pipe end face against the chamfering bite part that is rotating by connecting to the motor of the rotating device.

[0009]

EXAMPLE FIG. 1 is a sectional view of a pipe processing apparatus.

The automatic feeding device 2, the rotating device 3, the chuck 4, the cutting tool 5, and the chip collecting pipe are fixed to the support 10.

After the pipe 1 is set, the air cylinder of the automatic feeder 2 operates to fix the pipe 1 by the chuck 4, and the pulse motor DM operates to feed the specified amount of pipe. At the same time as the air cylinder of the automatic feeding device 2 operates to open the pipe 1, the air cylinder of the rotating device 3 operates to fix the pipe by the chuck 4. The DC motor M of the rotating device 3 operates to rotate the pipe, and the DC motor of the cutting tool 5 operates to send the tool to cut the pipe 1. After the cutting work, the air cylinders of the automatic feeding device 2 and the rotating device 3 are simultaneously activated again to grab the pipe 1 and send the specified amount of the pipe 1 to repeat the cutting work.

The pipe cut to the specified size is held in hand, and is connected to the DC motor M of the rotating device 3 and pressed against the rotating chamfering bite 6 to chamfer both end faces of the pipe 1. The chips generated during the chamfering process are sent to the chip collection pipe 9 by the impeller 7 and the guide plate 8, so that the chips are unlikely to enter the inside of the pipe.

[0013]

By adopting the automatic feeding device (auto bar feed), the length measuring work before cutting can be omitted, so the setup time can be reduced to 1/5 or less of the conventional one, and the total length dimension due to measurement error can be reduced. Can be reduced to 1/10 or less of the conventional value.

Since the chamfering bite is installed upward so as to collect chips, the cleanliness of the inside of the pipe can be secured and the cleaning work time after processing can be reduced to 1/5 or less of the conventional time.
