[Prior art]

 Generally, semiconductor manufacturing equipment is often designed compactly. For this reason, the tubes used in the device are tortuous because they are routed around the parts that make them up. Also, with a polymer tube, even if it is physically bent, it will not return to its original shape when the bending force is removed unless heat is applied, and the bent state cannot be maintained.

Therefore, conventionally, the bending of the polymer material type tube is performed by bending the tube with a tube processing tool and heating the bent portion in that state.

2 (a) and 2 (b) are views for explaining a conventional tube processing tool. In the figure, reference numeral 50 denotes a tube processing tool for bending a processed portion 5a of the tube 5. A tube fixing lever (tube fixing member) 1 for fixing the tube 5 at the tip 1b and a tube fixing lever 1 fixed to the tube fixing lever 1 for bending the processed portion 5a of the tube 5 along its side surface. A tube bending disc (form frame member) 3, a tube bending lever 2 whose tip 2b is rotatably attached to a central axis 3a of the tube bending disc 3, and a tip end side of the bending lever 2 It has a tube bending portion (pressing member) 4 which is attached and presses the processed portion 5a of the tube so that the processed portion 5a closely contacts the side surface of the disk 3. Reference numerals 1a and 2a denote handle portions at the rear ends of the tube fixing lever 1 and the tube bending lever 2, respectively. Reference numeral 6 is a dryer for heating the processed portion 5a of the tube.

Next, a tube processing method will be briefly described. First, as shown in FIG. 2 (a), the tube 5 is fitted into the tip portion 1b of the tube fixing lever 1, and the processed portion 5a of the tube 5 is sandwiched between the tube bending disk 3 and the tube pressure bending portion 4, In the state, the above-mentioned processed portion 5a is heated by the dryer 6. When the tubes 1 and 2a of the tube fixing lever 1 and the tube bending lever 2 are held by both hands while they are heated to some extent, the tube pressing portion 4 moves the processed portion 5a of the tube 5 It moves around the disk 3 while pressing it from the side of the fixed lever 1 to the side surface of the tube bending disk 3 in sequence, so that the processed portion 5a of the tube 5 is moved to the disk as shown in FIG. 2 (b). Turn along 3. In this state, one of the levers 1 and 2 is further sandwiched, for example, by the side of one arm, while holding the other lever with the same arm, hold the dryer 6 with the other hand and The bending portion 5a is heated so that it does not return to its original state, and the bending process is completed.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a view for explaining a tube processing tool according to an embodiment of the present invention. In FIG. 1, reference numeral 100 is the tube processing tool of this embodiment, and the same reference numerals as those in FIG. 2 are the same as those of a conventional processing tool. Is. In this processing tool 100, a tube bending disk (form frame member) 103 for performing bending and a tube pressure bending portion 104 are brought into contact with the main body portions 3b and 4b and the processed portion 5a of the tube 5, respectively. It is composed of heater built-in portions 3a and 4a for applying heat to the processed portion 5a. Here, the heater built-in portions 3a and 4a are detachable from the main body portions 3b and 4b, respectively, and are cartridge heaters having heater wires 3c and 4c therein, and the heater wires 3c and 4c are heaters. It is connected to the power supply 10.

Next, a tube processing method will be briefly described. First, the heater wires 3c and 4c of the tube bending disk 103 and the tube bending portion 104 are energized to raise the heater built-in portions 3a and 4a to a predetermined upper limit temperature, for example, 300 ° C. Then, as shown in FIG. 1 (a), the processed portion 5a of the tube 5 is in contact with the heater portion 4a of the tube bending portion 104, and this is along the side surface of the heater portion 3a of the tube bending disk 103. Secure it to the tube lock lever 1 so that it bends. After heating to some extent in this state, the grips 1a, 2a of the tube fixing lever 1 and the tube bending lever 2 are held by both hands and pulled together as in the conventional case. At this time, both levers 1 and 2 are moved so that the angle between them is acute. Then, the tube bending portion 104 moves around the disk 3 while sequentially pressing the processed portion 5a of the tube 5 from the side of the fixed lever 1 to the side surface of the tube bending disk 103, whereby the tube 5 of the tube 5 is moved. The processed portion 5a bends along the disk 103 as shown in FIG. 1 (b).

Further, in this state, the processed portion 5a of the tube 5 is heated by the heater portions 3a and 4a of the disk 103 and the bending portion 104 to prevent the bent portion of the tube from returning to its original position. This completes the bending process of the tube 1.

As described above, in this embodiment, the tube bending portion 104 and the tube bending disk 103 are structured such that the cartridge heaters 3a and 4a are detachably attached to the main body portions 3b and 4b, respectively, and the tube is bent. At this time, the tube 5 is sandwiched between the heater portion 4a of the tube bending portion 104 and the heater portion 3a of the tube bending disk 103 so that the portion to be processed 5a of the tube 5 is bent while being heated. Since it is not necessary to heat the tube to be processed with the dryer 6 etc. as in the conventional case, the processing tool can be always handled with both hands instead of one hand as in the conventional case. Further, during bending, the heater portions 3a and 4a of the tube bending disk 103 and the tube pressure bending portion 104, which come into contact with the tube, are heated to a high temperature, and thus the heat from this portion forms the tube 5. The movement of the molecule becomes active and the tube is easily bent. Thereby, the bending work can be easily performed.

Moreover, since the current applied to the heater wires 3c and 4c can be adjusted by the heater power supply 10, it is possible to always maintain the temperature necessary for accurately bending the tube, for example, the upper limit temperature of 300 ° C. The tube can be easily processed without causing damage to the tube. As a result, it is possible to obtain an effect of improving work efficiency that the polymer material tube can be processed easily in a short time with high accuracy.

Further, since the heater built-in portions 3a and 4a are of a cartridge type, maintenance of this portion is easy, and by preparing several kinds of the cartridge heaters according to the diameter of the tube, There is an effect that it can easily cope with tubes having different diameters.

In the above embodiment, the tube bending disk 103 and the tube pressure bending section 104 have the heater built-in portions 3a and 4a detachably attached to the body portions 3b and 4b, respectively. The tube bending disk 103 and the tube pressure bending section 104 may have a structure in which a heater is incorporated therein.

Further, the cartridge type member is not limited to the one having a built-in heater, but may be, for example, a ceramic heater which generates heat when energized. In this case, even if a failure occurs in the heater power source 10, the heater is overheated. However, there is an effect that the tube can be prevented from being damaged due to overheating and the safety can be improved.

Further, in the above description, the case of bending a tube made of a polymer material has been described, but the material of the tube is not limited to the polymer, and it goes without saying that the present invention can be applied to the tube processing of other materials. Yes.
