図10は片手曲げの例であり、対の受け突起8L、8Rの基部に取付孔A1が位置するようにプレートAを支え面12Bに受持させ、押付部9である中間径部9Dを凹部12Aに向って押付けることにより、片手曲げが可能とされているのである。この加工では、2つの取付孔A1間でプレートAを伸ばすこともできるが、取付孔A1の孔径は受け突起8L、8Rの径より大きいので、プレートAを伸ばすことなく曲げることができる。
FIGS. 8 and 9 are examples in which the bending R is 2 mm and 4 mm. The flat support surface 12B in the receiving portion 10 holds the plate A in the orthogonal direction, and the intermediate diameter portion 9D in the pressing portion 9 faces the concave portion 12A. Bending is performed by pinching operation of the manual operation unit 2 so that the bending R is 2 mm as shown by an imaginary line in FIG. 8. When the pressing portion 9 is the large diameter portion 9C, the bending R is 4 mm. It becomes.
FIG. 10 shows an example of one-hand bending, in which the plate A is supported on the support surface 12B so that the mounting hole A1 is located at the base of the pair of receiving projections 8L and 8R, and the intermediate diameter portion 9D as the pressing portion 9 is recessed. One-hand bending is enabled by pressing toward 12A. In this processing, the plate A can be stretched between the two mounting holes A1, but since the hole diameter of the mounting hole A1 is larger than the diameters of the receiving projections 8L and 8R, the plate A can be bent without stretching.

なお、図8の仮想線の曲げ加工及び図10の片手曲げのときは、中間径部9Dの両側面に形成した平坦面は、突起8L、8Rのガイド面9D−1、9D−2として機能する。
図11、12で示すように、プレートAを支え面12Bに対して斜め方向として保持させておき、押付部9の大径部9C又は中間径部9Dを押し付けることによって、ひねり曲げ加工をする。受け突起8L、8Rと小径部9Eとでも、ひねり曲げ加工は可能である。
なお、上述した曲げ加工において、加工部3にプレートAを軽く挟み例えば5秒以上(5〜20秒)、ヒータ13の発熱によって曲げ加工前に温めておき、プレートAが柔らかくなったところで軽く手動操作部2を握りしめることにより、加工部位を局部的に加熱して曲げ加工(塑性変形加工)を行うことができる。曲げ時の温度設定は任意ではあるけれども、縦曲げ時(図6参照)には80℃〜90℃の温度に設定され、縦曲げ時以外のときは95℃〜105℃の温度に設定することが好ましい。
8 and the one-handed bending in FIG. 10, the flat surfaces formed on both side surfaces of the intermediate diameter portion 9D function as the guide surfaces 9D-1 and 9D-2 of the protrusions 8L and 8R. To do.
As shown in FIGS. 11 and 12, the plate A is held in an oblique direction with respect to the support surface 12B, and the large-diameter portion 9C or the intermediate-diameter portion 9D of the pressing portion 9 is pressed to perform twist bending. Even the receiving protrusions 8L and 8R and the small diameter portion 9E can be twisted and bent.
In the above-described bending process, the plate A is lightly sandwiched between the processing parts 3 for 5 seconds or longer (5 to 20 seconds) and warmed by the heat generated by the heater 13 before the bending process. By grasping the operation unit 2, the processing part can be locally heated to perform bending (plastic deformation processing). Although the temperature setting at the time of bending is arbitrary, the temperature is set to 80 ° C. to 90 ° C. during vertical bending (see FIG. 6), and the temperature is set to 95 ° C. to 105 ° C. at times other than vertical bending. Is preferred.

グリップ4B、5Aには操作時の滑り止めのためにラバー(ゴム等の弾性ラバー)を付帯させることが望ましい。また、復帰手段7としては板バネ以外のコイル巻バネ等を採用することも可能である。
前記加工部3が、前記プレートAの取付孔A1に挿脱自在な対の受け突起8L、8Rとこの受け突起8L、8Rに保持されたプレートAを前記受け突起8L、8R間で曲げ加工する押付部9とで構成されていることにより、手で行うことが特に困難視されていた縦曲げ加工(厚さ方向と交差するプレート幅方向の加工)を正確かつ容易にできるのである(図6参照)。
It is desirable to attach rubber (elastic rubber such as rubber) to the grips 4B and 5A to prevent slipping during operation. Further, as the return means 7, it is also possible to employ a coil spring other than the leaf spring.
The processing section 3 bends the pair of receiving projections 8L and 8R which can be inserted into and removed from the mounting hole A1 of the plate A and the plate A held by the receiving projections 8L and 8R between the receiving projections 8L and 8R. By being configured with the pressing portion 9, the vertical bending process (processing in the plate width direction intersecting the thickness direction), which has been regarded as difficult to perform by hand, can be performed accurately and easily (FIG. 6). reference).

また、前記加工部3が、前記プレートAを受持する支え面12Bに凹部12Aを形成した受部10と前記支え面12Bに受持したプレートAを前記凹部12Aに向って曲げ加工する押付部9とで構成されていることにより、プレートAの取付孔A1間における曲げ加工(図5、8参照)およびひねり曲げ加工(図11参照)が可能となるのである。また、取り付け具の挿入に使用しないプレートAの取付孔A1の位置を曲げ加工部位とすることもできる。
前記押付部9に、プレートAを加熱するためのヒータ13が内蔵されていることにより、プレートAの素材(原料)が熱可塑性生体内分解吸収性高分子等の熱によって柔軟化されるものであるときは、ヒータ13に通電して押付部9を介してプレートAを加熱することによって、プレートAの曲げ加工においてひびが入ったり、破損したり、白濁するのを防止できるのである。
Further, the processing unit 3 is configured to bend the receiving portion 10 having the recess 12A formed in the supporting surface 12B for receiving the plate A and the plate A received to the supporting surface 12B toward the recess 12A. 9, the bending process (see FIGS. 5 and 8) and the twist bending process (see FIG. 11) between the mounting holes A1 of the plate A can be performed. Further, the position of the mounting hole A1 of the plate A that is not used for the insertion of the mounting tool can be set as a bending portion.
Since the heater 13 for heating the plate A is built in the pressing portion 9, the material (raw material) of the plate A is softened by the heat of a thermoplastic biodegradable polymer or the like. In some cases, by energizing the heater 13 and heating the plate A through the pressing portion 9, it is possible to prevent cracking, breakage, and cloudiness during bending of the plate A.

更に、前記押付部9が、段差部9A、9Bを介して大小異径部9C、9D、9Eが軸方向で段階的又はテーパー状に区分けされていることにより、曲げR1mm、2mm、4mmのような複数種類の曲げ加工ができるのである。ここで、大小異径部9C、9D、9Eとは、大・小2種類と、大・中・小の3種類を含む概念であり、更に、その種類を増やしてもよいし、適宜の角度で軸方向にテーパー状としてもよい。
図13〜21に基づいて、本発明の第2の実施の形態について説明する。
図13〜21において、第2実施形態の骨接合用プレートの加工用具1で、前記第1実施形態の加工用具1と同一の部及び部材、同様な作用をする部及び部材については、同一符号を使用している。
Further, the pressing portion 9 is formed such that the large and small diameter portions 9C, 9D, and 9E are stepped or tapered in the axial direction via the step portions 9A and 9B, so that the bending R1mm, 2mm, and 4mm Multiple types of bending can be performed. Here, the large and small different diameter portions 9C, 9D, and 9E are concepts including two types of large / small and large / medium / small, and the number of types may be increased, or an appropriate angle The taper may be tapered in the axial direction.
A second embodiment of the present invention will be described based on FIGS.
13 to 21, in the processing tool 1 of the osteosynthesis plate of the second embodiment, the same reference numerals are used for the same parts and members as those of the processing tool 1 of the first embodiment, and the parts and members that perform the same functions. Is used.

加工用具1は、手動操作部2と、この手動操作部2の操作で前記プレートAを曲げ加工する加工部3とを備えて主構成されている。前記加工部3は、押え側アーム(挟み部材)5に備えられている押付部(押し部)9とその受け側アーム(受け部材)4に備えられている受部10とからなり、開閉自在な押付部9と受部10に第1加工部3A、第2加工部3B、第3加工部3Cを軸方向に区分けして構成されている。
第1加工部3Aは受部10の先端に受けブロック10Aをネジ10Bで着脱自在に取付け、受けブロック10Aの上面に対の受け突条8L、8Rを間隔を有して平行に隆起形成し、この対の受け突条8L、8RにプレートAを、図17の仮想線で示すようにかけ渡して加工部位近傍を2点で支持し、押付部9における丸棒で形成した小径部9EをプレートAの加工部位に当接し、対の突条8L、8R間の凹み10Cに向って押下げることによって、そのプレートAが取付孔A1又は取付孔A1間において厚み方向に曲げ加工されるように構成されている。
The processing tool 1 mainly includes a manual operation unit 2 and a processing unit 3 that bends the plate A by the operation of the manual operation unit 2. The processing portion 3 is composed of a pressing portion (pressing portion) 9 provided on the presser side arm (pinching member) 5 and a receiving portion 10 provided on the receiving side arm (receiving member) 4, which can be freely opened and closed. The pressing portion 9 and the receiving portion 10 are configured by dividing the first processing portion 3A, the second processing portion 3B, and the third processing portion 3C in the axial direction.
The first processing portion 3A is detachably attached to the receiving block 10A at the tip of the receiving portion 10 with screws 10B, and a pair of receiving protrusions 8L and 8R are formed in parallel on the upper surface of the receiving block 10A with a gap therebetween, The plate A is passed over the pair of receiving protrusions 8L and 8R as shown by phantom lines in FIG. 17 to support the vicinity of the processing portion at two points, and the small diameter portion 9E formed by a round bar in the pressing portion 9 is formed on the plate A. The plate A is configured to be bent in the thickness direction between the mounting holes A1 or A1 by being pressed down toward the recess 10C between the pair of protrusions 8L and 8R. ing.

なお、対の受け突条8L、8Rにおける頂部の形状は任意であるが、図17に示すように、丸味形状とすることによって、その頂部に板面がかけ渡されたプレートAを曲げ加工するとき、板面が滑動して正確で傷がない曲げ加工ができて有利となる。また、対の受け突条8L、8Rと小径部9Eとを逆に見れば、小径部9EでプレートAの加工部位を支持し、対の受け突条8L、8RでプレートAの加工部位近傍を小径部9E側に押圧することになる。
第2加工部3Bは図18で示すように、前記第1加工部3Aよりも緩やかな曲げ加工、及び図19で示すように、ひねり曲げ加工するものであり、第1実施形態と同様に、次のように構成されている。
In addition, although the shape of the top part in the pair of receiving protrusions 8L and 8R is arbitrary, as shown in FIG. 17, the plate A having a plate surface spanned over the top part is bent by forming a round shape. When the plate surface slides, it is advantageous in that it can be bent accurately and without scratches. If the pair of receiving protrusions 8L and 8R and the small diameter portion 9E are viewed in reverse, the small diameter portion 9E supports the processing portion of the plate A, and the pair of receiving protrusions 8L and 8R near the processing portion of the plate A. It will press to the small diameter part 9E side.
As shown in FIG. 18, the second processed portion 3B is a bending process gentler than the first processed portion 3A, and a twisted bending process as shown in FIG. 19, and as in the first embodiment, It is structured as follows.

図16、18、19に示すように、受部10の上面に形成した平坦な支え面12Bの中央部位にアーム長手方向に延びる円弧状の溝である凹部12Aを形成して対の台状の支え部12とし、前記支え面12Bに受持したプレートAを前記凹部12Aに向って押動する丸棒状の中間径部9Dによる押付部9とで、第2加工部3Bが構成されている。
従って、プレートAを支え面12Bに傾斜状としてその板面を受持した状態で、押付部9における中間径部9Dを押下げることによって、ひねり曲げ加工も可能である。
第3加工部3Cは前記プレートAを縦曲げ加工するものであり、次のように構成されている。
As shown in FIGS. 16, 18, and 19, a recess 12 </ b> A that is an arc-shaped groove extending in the arm longitudinal direction is formed in the central portion of the flat support surface 12 </ b> B formed on the upper surface of the receiving portion 10 to form a pair of trapezoidal shapes. The second processing portion 3B is configured by the support portion 12 and the pressing portion 9 formed by a round bar-shaped intermediate diameter portion 9D that pushes the plate A held on the support surface 12B toward the recess 12A.
Therefore, twist bending can be performed by pressing down the intermediate diameter portion 9D of the pressing portion 9 in a state where the plate A is inclined on the support surface 12B and held on the plate surface.
The 3rd process part 3C carries out the vertical bending process of the said plate A, and is comprised as follows.

図16(1)(2)において、第2加工部3Bに隣接してプレートAの板面を受持する平坦な支え面18が、段差部18Aを介して受部10の上面に形成されている。この支え面18にはプレートAと係合可能な複数本の突起、即ち、図では4本の丸棒で例示するピン19(19A、19B、19C、19D)が植立されて、突起状支え部12を形成している。
具体的には、支え面18の幅方向略中央部に軸方向の間隔を有して中央の第1・2のピン19A、19Bを配列し、軸方向の左右(幅方向)に振り分けて第3・4のピン19C、19Dが第2のピン19B寄りに配列され、前記第1〜4のピン19A〜19DはプレートAに形成した取付孔A1に挿脱自在であり、プレートAの縁(取付孔A1間のクビレ部の外周縁をいい、以下同じ)がピン19外周に対して係合するようにされている。
16 (1) and 16 (2), a flat support surface 18 that receives the plate surface of the plate A adjacent to the second processed portion 3B is formed on the upper surface of the receiving portion 10 through the step portion 18A. Yes. A plurality of protrusions that can be engaged with the plate A, that is, pins 19 (19A, 19B, 19C, 19D) illustrated as four round bars in the figure are planted on the support surface 18 so as to support the protrusions. Part 12 is formed.
Specifically, the first and second pins 19A and 19B in the center are arranged at a substantially central portion in the width direction of the support surface 18 with an axial interval, and the first and second pins 19A and 19B are arranged in the left and right sides (width direction) in the axial direction. The third and fourth pins 19C and 19D are arranged near the second pin 19B, and the first to fourth pins 19A to 19D can be inserted into and removed from the mounting holes A1 formed in the plate A, and the edge of the plate A ( The outer peripheral edge of the constricted portion between the mounting holes A <b> 1 is the same, and the same applies to the outer periphery of the pin 19.

第1〜4のピン19A〜19Dは、受部10にその下面側からネジ込み等によって突出量調整自在に植立されており、ネジ18Bによって抜け止めされている。
更に、第1〜4のピン19A〜19Dの植立高さ(支え面18からの突出量)は、プレートAの板厚とほぼ同厚か多少の厚薄とされており、支え面18に重ね合されたプレートAの取付孔A1をピン19に挿通して縦曲げ加工するとき、ピン19からプレートAが安易に離脱しないようにされている。
第3加工部3Cにおける押付部9の大径部9Cが、この閉じ姿勢で支え面18と対面しているとともに、図16(1)で示すように、ピン19A〜19Dと接触しないようにスキマを有し、大径部9Cの下面には平坦面(挟み部)9Fが形成され、閉じ姿勢で実質的にこの平坦面9Fが支え面18と対面し、プレートAがピン19A〜19Dとの係合から離脱するのを防止している。前記平坦面9FはプレートAと当接して挟持することが好ましいが、両者の間にスキマが形成されても支障はない。
The first to fourth pins 19 </ b> A to 19 </ b> D are planted in the receiving portion 10 so as to be adjustable in protruding amount by screwing or the like from the lower surface side, and are prevented from being detached by screws 18 </ b> B.
Furthermore, the planting heights of the first to fourth pins 19 </ b> A to 19 </ b> D (the amount of protrusion from the support surface 18) are almost the same as or slightly thinner than the plate A, and are stacked on the support surface 18. When the mounting hole A1 of the combined plate A is inserted into the pin 19 and subjected to vertical bending, the plate A is prevented from being easily detached from the pin 19.
The large-diameter portion 9C of the pressing portion 9 in the third processed portion 3C faces the support surface 18 in this closed posture, and as shown in FIG. 16 (1), the clearance is prevented from coming into contact with the pins 19A to 19D. A flat surface (pinching portion) 9F is formed on the lower surface of the large-diameter portion 9C. The flat surface 9F substantially faces the support surface 18 in the closed position, and the plate A is connected to the pins 19A to 19D. It prevents it from being disengaged. The flat surface 9F is preferably held in contact with the plate A, but there is no problem even if a gap is formed between them.

次に、図17〜21を参照して、第2実施形態のプレートAのベンディング(曲げ加工)の作業方法について説明する。
第1加工部3Aでは、曲げRが1mm前後の平板曲げ加工を主に行い、縦曲げ加工をするのは若干困難になっており、第2加工部3Bでは、曲げRが2〜5mm前後の平板曲げ加工を主に行う。
縦曲げ加工は第3加工部3Cで主に行われる。図20において、第3加工部3Cを開いた状態(手動操作部2を握ってない状態)にしておいて、プレートAの取付孔A1に例えば第3ピン19Cを挿通して支え面18にプレートAの広面を重ね合せ、プレートAの側縁A2、すなわち、隣り合う取付孔A1間におけるクビレ部の外周縁が第4ピン19Dに係合するようにセットする。
Next, with reference to FIGS. 17-21, the working method of the bending (bending) of the plate A of 2nd Embodiment is demonstrated.
In the first processed part 3A, the bending R is mainly performed by flat plate bending with about 1 mm, and it is somewhat difficult to perform vertical bending. In the second processed part 3B, the bending R is about 2 to 5 mm. Mainly plate bending.
Longitudinal bending is mainly performed in the third processed portion 3C. In FIG. 20, with the third processed portion 3C opened (the manual operation portion 2 is not gripped), for example, the third pin 19C is inserted into the mounting hole A1 of the plate A, and the plate is formed on the support surface 18. The wide surfaces of A are overlapped, and the side edge A2 of the plate A, that is, the outer peripheral edge of the constricted portion between the adjacent mounting holes A1 is set to engage with the fourth pin 19D.

次いで、手動操作部2を軽く握り、押付部9を閉じ姿勢にし、ヒータ13に通電してプレートAを温める。この際、押付部9は受部10と相まってプレートAを挟持してもよいし、第3ピン19Cから抜けないように近接しているだけでもよい。
次に、手動操作部2を軽く握ったまま、プレートAに矢示Fのように手指によってゆっくり軽い力で曲げると、第3ピン19Cが固定で第4ピン19Dを支点とする縦曲げ加工がなされる。即ち、プレートAの端部に肉厚方向と交差する幅方向の力を加えていくと、第3ピン19Cが支点となり、第3ピン19Dと当接して抵抗を受け、この第3ピン19D近傍で曲げが生じる。
Next, the manual operation unit 2 is lightly gripped, the pressing unit 9 is closed, the heater 13 is energized, and the plate A is heated. At this time, the pressing portion 9 may sandwich the plate A in combination with the receiving portion 10 or may be close to the third pin 19C so as not to come off.
Next, when the manual operation unit 2 is lightly gripped, the third pin 19C is fixed and the vertical bending process using the fourth pin 19D as a fulcrum is performed by slowly bending the plate A with fingers as indicated by an arrow F. Made. That is, when a force in the width direction intersecting with the thickness direction is applied to the end portion of the plate A, the third pin 19C serves as a fulcrum, abuts against the third pin 19D and receives resistance, and the vicinity of the third pin 19D Causes bending.

この縦曲げ加工は手指で行うが、プレートAが第3加工部3Cにおいて押付部9と受部10で挟み込まれ、しかも、第3ピン19Cが取付孔A1に挿通されているので、プレートAの保持は確実となり、縦曲げ作業であっても正確にできる。
曲げ加工後、押付部9を開いてピンからプレートAを外し、このプレートAの曲げ加工部が第1ピン19Aに係合するようにプレートAを支え面18にセットし、押付部9を閉じ状態にしてからプレートAの両端張り出し部分に矢示Fのようにゆっくりと軽い力で仕上げ曲げ加工をする。
This vertical bending is performed with fingers, but the plate A is sandwiched between the pressing portion 9 and the receiving portion 10 in the third processed portion 3C, and the third pin 19C is inserted through the mounting hole A1, so that the plate A Retention is ensured and can be accurately performed even in a vertical bending operation.
After bending, the pressing portion 9 is opened to remove the plate A from the pin. The plate A is set on the support surface 18 so that the bending portion of the plate A engages the first pin 19A, and the pressing portion 9 is closed. After the condition is reached, finish bending is performed on the protruding portion of both ends of the plate A with a light force slowly as indicated by arrow F.

このように曲げ加工されたプレートAは、第3加工部3Cから外され、余熱で柔らかい間に手指によって形状を修正することで、ここに縦曲げ加工が完了する。
前記仕上げ曲げ加工の形態のみで曲げ加工をすることもできる。即ち、直線状のプレートAを第1ピン19Aと第3、4ピン19C、19Dとの間に挿入し、プレートAの取付孔A1を第1ピン19Aに嵌合又はプレートAの取付孔A1間を第1ピン19Aに当接して支持し、プレートAの両端部をプレートA幅方向でかつ同一方向に矢示Fの力を加えることにより、直線形状から直接曲げることもできる。
The plate A thus bent is removed from the third processed portion 3C, and the vertical bending process is completed here by correcting the shape with fingers while soft due to the residual heat.
Bending can be performed only in the form of the finish bending. That is, the straight plate A is inserted between the first pin 19A and the third and fourth pins 19C and 19D, and the mounting hole A1 of the plate A is fitted to the first pin 19A or between the mounting holes A1 of the plate A. Can be bent directly from the linear shape by applying a force indicated by an arrow F in the width direction of the plate A and in the same direction at both ends of the plate A.

図21は、緩やかな曲率での縦曲げ加工の例を示している。第2ピン19BにプレートAの取付孔A1を挿通するとともに、この取付孔A1の両側に隣接するプレートAの側縁A2を第3、4ピン19C、19Dに係合させ、押付部9を閉じ姿勢にしてプレートAを温め、手動操作部2を軽く握った状態で、手指によってプレートAを矢示Fのようにゆっくり軽い力で曲げると、第3ピン19Cが曲げ反力を受けるように係合するので、第2ピン19Bを支点にプレートAが縦曲げ加工される。
次いで、押付部9を開いた状態で、第1段の縦曲げ加工されたプレートAを左右反転して第2ピン19Bにセットするとともに、第3、4ピン19C、19DにプレートAの側縁A2を係合させ、プレートAの張出し部に矢示Fの曲げを軽い力で付与すると、プレートAはその長手方向中央部を弯曲部としての縦曲げが完了する。
FIG. 21 shows an example of vertical bending with a gentle curvature. The mounting hole A1 of the plate A is inserted into the second pin 19B, the side edge A2 of the plate A adjacent to both sides of the mounting hole A1 is engaged with the third and fourth pins 19C and 19D, and the pressing portion 9 is closed. In a state where the plate A is warmed in the posture and the manual operation unit 2 is lightly gripped, if the plate A is slowly bent with a light force as indicated by an arrow F, the third pin 19C receives a bending reaction force. Therefore, the plate A is vertically bent with the second pin 19B as a fulcrum.
Next, with the pressing portion 9 opened, the first-stage vertically bent plate A is reversed left and right and set on the second pin 19B, and the side edges of the plate A on the third and fourth pins 19C and 19D. When A2 is engaged and the bending of the arrow F is applied to the overhanging portion of the plate A with a light force, the plate A is completely bent in the longitudinal direction with the central portion in the longitudinal direction as the bent portion.

次いで、プレートAを第3加工部3Cより外し、余熱で柔らかい間に手指によって形状を修正するのである。
前記段差部18AはプレートAと当接すると支持抵抗を与えてピン19A〜19Dと同様な役目をさせることができ、前記ピン19A〜19Dは1本でもよいが、複数本を適宜位置に配置するほうが、プレートAの曲げ形態を多様にすることができる。
図18(1)は第2加工部3Bによる曲げRが例えば2.5mmの加工の例であり、受部10における平坦な支え面12BにプレートAを受持させ、押付部9における中間径部9Dを凹部12Aに向って手動操作部2の挟み付け操作で曲げ加工することにより、図18で示すように、プレートAは曲げRが2.5mmの曲げ加工となるのである。
Next, the plate A is removed from the third processed portion 3C, and the shape is corrected with fingers while it is soft with residual heat.
When the step portion 18A comes into contact with the plate A, it can provide a support resistance to play the same role as the pins 19A to 19D. The number of the pins 19A to 19D may be one, but a plurality of the pins 19A to 19D are arranged at appropriate positions. However, the bending form of the plate A can be varied.
FIG. 18A is an example of processing in which the bending R by the second processing portion 3B is, for example, 2.5 mm. The flat support surface 12B in the receiving portion 10 receives the plate A, and the intermediate diameter portion in the pressing portion 9 is obtained. By bending 9D toward the concave portion 12A by the clamping operation of the manual operation unit 2, the plate A is bent with a bending R of 2.5 mm as shown in FIG.

更に、図19(1)(2)はひねり曲げの例であり、第2加工部3BにおいてプレートAを支え面12Bに対して斜め方向として保持させておき、押付部9の押付によってひねり曲げ加工を可能とする。
前述例では第1〜3加工部3A、3B、3Cをその順序で軸方向に区分けしているが、第1加工部3Aと第2加工部3B、第1加工部3Aと第3加工部3C、第2加工部3Bと第3加工部3Cの組合せであっても構わなく、また長手方向位置を変更してもよい。
なお、本発明は前記実施の形態に限定されるものではなく、種々変形することができる。例えば、プレートAの加熱としては、加工部3を事前に予熱しておいたり、その加工部3を閉じ状態でキャップを被せるようにしたりしてもよい。
Further, FIGS. 19 (1) and 19 (2) are examples of twist bending, in which the plate A is held in an oblique direction with respect to the support surface 12B in the second processing portion 3B, and twist bending is performed by pressing the pressing portion 9. Is possible.
