ある。(Prior Art) Conventionally, as a thermoplastic synthetic resin thermal processing tool of this type (hereinafter referred to as a thermal processing tool), one having a configuration as shown in FIG. 17 is known. (Unexamined Japanese Patent Publication No. 56-46721
To explain the drawings, a support rod 2 made of cylindrical metal is inserted onto the central axis of a cooling section 1 having a large number of radially formed fins, and a support rod 2 having an arcuate cross section is inserted at the tip of the rod 2. A recess 2a is bored, and a thin sheet-like heating element 4 is fixed to the recess 2a via a heat-resistant electrically insulating sheet 3.

た。 Therefore, when the heating element 4 is energized, the heating element 4 rises to the required temperature, locally heating the thermoplastic synthetic resin protrusion in contact with the recess 2a and melting it. It is possible to perform caulking that follows the shape of the hole 2a. However, in this thermal processing tool, the recess 2a, which is the processing contact part, is directly connected to the heating element 4.
This structure is effective in improving responsiveness of heat generated by energization, but since it comes into direct contact with the resin, it is prone to damage and has poor durability. Since the entire area covered with 4 generates heat, there is a risk of heating, melting, deforming or burning out the resin in other non-processed areas, which requires skill and is unsuitable for caulking in small areas. There were many problems with this.

To explain Fig. 8, the tip 5a is formed in the shape of a truncated cone, and a heater 8 such as a cartridge heater is mounted vertically in a bullet-shaped cylindrical body 7 having a recess 6 at the tip. In particular, since the heater 8 can supply heat locally and directionally to the cutting edge recess 6, it has the advantage of being able to carry out thermal welding processing with much higher performance than the aforementioned thermal processing tools. be. However, in any of the conventional examples, when the power supply is stopped to eliminate the thermal energy supplied to the recesses 2a and 6, a rapid heat dissipation effect cannot be obtained because the heat capacity of the support rod 2 and the cylindrical body 7 themselves are large. The reality is that cooling gas is forcibly added to the latter cylindrical body 7 in order to improve the heat dissipation effect.

There were also disadvantages such as poor processing results if cooling was insufficient.

わち切欠部１４の体積Ａは、つぎのように計算
される。(i) The central axis of the thermal processing tool body 9 is the x-axis, the axis that crosses approximately the center of the narrow portion 13 is the y-axis, and the center is on the y-axis and the arc of radius R2 is formed around the x-axis. The volume A of the half-moon-shaped notch, that is, the notch 14 when rotary cutting is performed, is calculated as follows.
Ｖ＝π∫b -a｛（−0.176×＋2.44）2−（3.6√22−
2）
2｝dx
＝π∫1.421.81｛（−0.176×＋2.44）2−（3.6√2
2−
x2）2｝dx
より、
Ａ≒18.98（mm3）
なお切欠前の体積Ｂは
Ｂ＝61.2（mm3）
したがつて狭小部１３の体積Ｃは
Ｃ＝Ｂ−Ａ
＝42.22（mm3）
さらに中心軸に穿つたヒータ１０挿通用の孔
の体積（φ0.65）を除くと41.15（mm3）となる。 V=π∫ b -a {(-0.176×+2.44) 2 −(3.6√2 2 −
2 )
2 }dx = π∫ 1 . 421 . 81 {(−0.176×+2.44) 2 −(3.6√2
2 −
x 2 ) 2 }dx, A≒18.98 (mm 3 ) The volume B before the notch is B = 61.2 (mm 3 ) Therefore, the volume C of the narrow part 13 is C = B - A = 42.22 (mm 3 ) Furthermore, if we exclude the volume of the hole (φ0.65) drilled in the center shaft for inserting the heater 10, the volume becomes 41.15 (mm 3 ).
したがつて実際の狭小部１３の体積は41.15
（mm3）となりこの体積32％減である。 Therefore, the actual volume of the narrow part 13 is 41.15
(mm 3 ), which is a 32% reduction in volume.
(ii) つぎに、狭小部１３の最も小さい個処の断面
積について計算する。(ii) Next, calculate the cross-sectional area of the smallest portion of the narrow portion 13.
切欠前……2.442π−0.3252π＝18.36（mm3）
切欠後……1.62π−0.3252π＝7.7（mm3）
したがつて切欠後の断面積7.7（mm3）は切欠
前断面積に比べて42％減となる。 Before the notch...2.44 2 π-0.325 2 π=18.36 (mm 3 ) After the notch...1.6 2 π-0.325 2 π = 7.7 (mm 3 ) Therefore, the cross-sectional area after the notch is 7.7 (mm 3 ) before the notch This is a 42% reduction compared to the cross-sectional area.
(iii) 狭小部１３の長さＬは切欠前の長さｌに比し
17％増となる。(iii) The length L of the narrow part 13 is compared to the length l before the notch.
This is an increase of 17%.
(iv) 狭小部１３の最も小さい個処の厚みｔは、切
欠前に比して440％減である。(iv) The thickness t of the smallest part of the narrow part 13 is reduced by 440% compared to before the notch.
なお上述の計算に当つては、つぎの函数を下
に行つた。 In addition, in the above calculation, the following function was used below.
x2＋（ｙ−3.6）2＝22
ｙ＝−xtan10゜＋2.44
今、前記計算で得られた結果を、第３図により
図示する共に加工当接部１５の温度変化を狭小部
１３のない場合と対比して検討した。x 2 + (y-3.6) 2 = 2 2 y = -xtan10° + 2.44 Now, the results obtained by the above calculation are illustrated in FIG. A comparison was made with the case without.
この図表から分るように、切欠部１４のない場

る。このことは両者の温度差が顕著で狭小部１３
を形成した方が温度差58％増となることを示すに
外ならない。 As can be seen from this chart, the difference between the case without the notch 14 and the case with the narrow part 13 formed by the notch 14 is that the former has a temperature change of 240°C to 297°C due to NO/OFF of the heater 10. It can be seen that the temperature is 57°C, while the latter is 90°C, which is between 200°C and 300°C. This means that the temperature difference between the two is significant and the narrow portion 13
This clearly shows that the temperature difference will increase by 58% if .
この顕著な相異は、狭小部１３の断面積の大き
さが影響しているもので、この狭小部１３の形成
により、ヒータ１０のON，OFFが加工当接部１
５の温度の上昇、下降に敏感に作用し、しかもそ
の温度差を大きくとれるものである。 This remarkable difference is caused by the size of the cross-sectional area of the narrow part 13. Due to the formation of this narrow part 13, the ON/OFF of the heater 10 is controlled by the processing contact part 1.
It acts sensitively to the rise and fall of the temperature mentioned in No. 5, and can handle a large temperature difference.
