Description
本発明はパイプ曲げ技術分野に関し、具体的にパイプ曲げ機である。 The present invention relates to the field of pipe bending technology, and more particularly to a pipe bending machine.
現在、工業生産および建設などの業界では、様々な金属材料がよく使用され、異なる製品の製造や異なる場所で必要とされる金属材料の形状および湾曲度に対する要件もまた異なり、しかも科学技術の絶え間ない進歩と発展に伴い、金属材料の品質と製品品質に対する要求もますます高くなり、その中には、金属材料に曲げ処理を実行する装置であるパイプ曲げ機があり、それは中空の金属管を一定の角度で曲げることができるだけでなく、中実の金属材料の変形加工を行うこともでき、従来のパイプ曲げ機には手動、伝動および空気圧などのいくつかの分類がある。例えば、中国特許は、「空気圧式パイプ曲げ機」（特許番号：ＣＮ１０２２４８０４３Ｂ）を開示しおり、この特許は、作業台、シリンダおよびシリンダアセンブリ、パイプ曲げ押圧溝および転がり溝を含み、この技術的解決手段は主に吸気管を介してエアポンプに接続され、曲げる対象のパイプをパイプ曲げの押圧溝に置き、ジョイスティックを作業方向に回し、エアバルブは空気圧をホースを介してシリンダに送り、シリンダーピストンの背部の空気圧は前方の空気圧より大きく、伸縮軸棒とパイプ曲げ押圧溝を作業台に向かって進めるように作動し、最後的に鋼管はパイプ曲げ押圧溝と転がり溝との間に力を受けて設定角度まで曲げた後、ジョイスティックを反対方向に動かし、伸縮軸棒とパイプ曲げ押圧溝を初期位置まで後退させ、曲げられたエルボを取り出す。例えば、中国特許は「曲げ機械」（特許番号：ＣＮ１０２５５３９８８Ｂ）を開示しおり、この特許は、フレーム、動力出力装置、および動力軸を含み、この技術的解決手段は主に、曲げる対象の円形管を位置決めブロックの貫通孔、第１の半円形溝と第２の半円形溝によって形成された円形溝を貫通し、続いて動力出力装置を起動して動力軸の回転を駆動し、動力軸によって曲げアームを駆動してホイールの周りをある方向に回転させ、同時に、曲げアームのスロット内の曲げバーが円形溝を貫通した円形管を折り曲げ、曲げアームがある角度で回転して円形管を湾曲させる必要がある要件に達すると、モータの停止を制御して曲げアームの回転を停止させるように制御することができ、曲げ成形した円形管を取り出すことができる。上記の技術的解決手段および既存の使用されているいくつかのパイプ曲げ装置は、短い金属材料または長い金属製品の曲げ加工に対して、いくつかの非常に重要な問題を避けることができない：金属材料自体はある程度の弾性を有し、曲げ作業後にはその自体が変形回復の動きを有し、これが曲げ角度に一定の偏差を生じさせ、成形を行うことができるようにするために何度も繰り返し曲げ作業を行う必要があり、金属材料を曲げる時に、角の内側に集まりが発生し、外側に伸張動作が発生し、それは金属材料が切断されやすく、角が滑らかにならなくなったりすることを引き起こしやすい。 Today, in industries such as industrial production and construction, various metal materials are often used, and the requirements for shape and curvature of metal materials required for manufacturing different products and in different places are also different, and the technological continuity is constant. With no progress and development, the demands on the quality of metal materials and product quality are also increasing, among them is the pipe bending machine, which is a device for performing bending treatment on metal materials, which is a hollow metal pipe. Not only can it be bent at a certain angle, but it can also be used for deformation processing of solid metal materials, and there are several categories of conventional pipe bending machines such as manual, transmission and pneumatic. For example, a Chinese patent discloses a "pneumatic pipe bending machine" (patent number: CN1022248043B), which includes a workbench, a cylinder and a cylinder assembly, a pipe bending pressure groove and a rolling groove, and this technical solution. Is mainly connected to the air pump through the intake pipe, puts the pipe to be bent in the pressing groove of the pipe bending, turns the joystick in the working direction, the air valve sends the air pressure to the cylinder through the hose, and the back of the cylinder piston The air pressure is higher than the air pressure in the front, and it operates so as to advance the telescopic shaft rod and the pipe bending pressure groove toward the workbench, and finally the steel pipe receives a force between the pipe bending pressure groove and the rolling groove to set the angle. After bending, move the joystick in the opposite direction to retract the telescopic shaft rod and pipe bending pressure groove to the initial position, and take out the bent elbow. For example, a Chinese patent discloses a "bending machine" (patent number: CN102553988B), which includes a frame, a power output device, and a power shaft, and the technical solution is mainly for a circular tube to be bent. Penetrating through the through hole of the positioning block, the circular groove formed by the first semi-circular groove and the second semi-circular groove, and then activating the power output device to drive the rotation of the power shaft and bend it by the power shaft. The arm is driven to rotate around the wheel in a certain direction, at the same time, the bending bar in the slot of the bending arm bends the circular tube through the circular groove, and the bending arm rotates at an angle to bend the circular tube When the required requirement is reached, the motor stop can be controlled to stop the rotation of the bending arm and the bend-formed circular tube can be removed. The above technical solution and some of the existing pipe bending equipment in use cannot avoid some very important problems for bending short metal materials or long metal products: metal The material itself has a certain elasticity, and after bending operation itself has a deformation recovery movement, which causes a certain deviation in the bending angle, which is repeated many times in order to be able to perform molding. Repeated bending work is required, and when bending the metal material, clusters occur inside the corners and stretching motions occur outside, which can easily cut the metal material and make the corners less smooth. Easy to cause.

このパイプ曲げ機が作動中（または使用中）には、まず、曲げ処理を施す必要がある金属ロッドまたは金属パイプをセラミックプレート１０３とセラミックコラム１０４との間の残しておいたスペースに直接係合させ、次いでプッシュボルト１０７５を直接回転させ、プッシュボルト１０７５の連続移動によって、曲げブロック１０８１と固定トレイ１とが当接するまで曲げ機構１０８を固定トレイ１に向けってゆっくり押し、この状態で曲げ機構１０８内の曲げローラ１０８３が金属パイプの外壁と接触し、続いて装置全体の電源を入れ、スタートボタンを押し、周波数変換器１０７４１に電流を通し、周波数変換器１０７４１が民間電力を高周波電力に変換して第２のコイル１０８７に送り、第２のコイル１０８７は曲げ機構１０８の移動に伴って第１のコイル１０９のポートと接し、複数の第１のコイル１０９及び第２のコイル１０８７は１つの一定長さの閉回路を構成し、局部金属パイプはこの回路の中央に位置し、金属パイプの局部位置は急速に加熱されて焼成され、続いて、回転ハンドル１０７６を引いてレバーアームプレート１０７を駆動して取り付けボルト１０６を中心に回転させ、それとともに曲げ機構も回転させ、曲げローラ１０８３は焼成部分をセラミックコラム１０４に密着して押し付けて変形させ、コイルの連続移動につれて、この開閉動作が繰り返され、回転の全過程において、金属パイプの各部分を、所望の曲げ部分への加工が完成するまで、加熱して焼成する。 When the pipe bending machine is in operation (or in use), first, the metal rod or metal pipe that needs to be bent is directly engaged with the remaining space between the ceramic plate 103 and the ceramic column 104. Then, the push bolt 1075 is directly rotated, and by continuous movement of the push bolt 1075, the bending mechanism 108 is slowly pushed toward the fixed tray 1 until the bending block 1081 and the fixed tray 1 come into contact with each other. The bending roller 1083 in 108 comes into contact with the outer wall of the metal pipe, then turns on the power of the entire apparatus, presses the start button, passes current to the frequency converter 10741, and the frequency converter 10741 converts private power to high frequency power. Then, the second coil 1087 contacts the port of the first coil 109 as the bending mechanism 108 moves, and the plurality of first coils 109 and second coils 1087 form one A fixed length closed circuit is formed, the local metal pipe is located in the center of this circuit, the local position of the metal pipe is rapidly heated and fired, and then the rotary handle 1076 is pulled to pull the lever arm plate 107. The mounting bolt 106 is driven to rotate about the mounting bolt 106, and the bending mechanism is also rotated together with it, and the bending roller 1083 presses the fired portion in close contact with the ceramic column 104 to deform it, and this opening/closing operation is repeated as the coil continuously moves. Then, in the whole process of rotation, each part of the metal pipe is heated and fired until processing into a desired bent part is completed.
上記のように、このパイプ曲げ機は、金属パイプの焼成状態で押し付けて曲げる作業を行い、金属パイプ内の原子が非常に活発な状態にあり、不規則運動下で曲げ部分を補償動作することができるので、曲げ部分をより滑らかでより自然にし、同時に、焼成状態での曲げ処理後の成形がより安定し、曲げ部分ではね返り作用が起こりにくくなり、曲がった角での誤差値を低下させる。 As mentioned above, this pipe bending machine performs bending work by pressing in the fired state of the metal pipe, the atoms in the metal pipe are in a very active state, and compensating the bending part under irregular motion As a result, the bending part becomes smoother and more natural, and at the same time, the forming after the bending process in the baked state is more stable, the rebound effect does not easily occur in the bending part, and the error value at the bent corner is reduced. ..
