【発明の詳細な説明】
本発明は、熱可塑性樹脂管、特にポリエチレン管同志を
熱溶着するに適したパット溶着装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pad welding device suitable for thermally welding thermoplastic resin pipes, particularly polyethylene pipes together.
従来、この種パット溶着装置としては、台盤上に固定ク
ランプと移動クランプとを配設し、該移動クランプをエ
アシリンダーあるいは油圧シリンダーの作動によつて移
動させるようにしたものが公知である。Conventionally, this type of pad welding apparatus is known in which a fixed clamp and a movable clamp are disposed on a base plate, and the movable clamp is moved by the operation of an air cylinder or a hydraulic cylinder.
そして、熱可塑性樹脂管同志を熱溶着する場合には、固
定クランプと移動クランプとに熱可塑性樹脂管の管先端
部を若干突出した状態に保持し、それぞれの熱可塑性樹
脂管の端面を面取りした後、各管端面を熱板に押付けて
加熱溶融し、次いでこの溶融した管端面同志を突合わせ
て溶着接合していた。When heat welding thermoplastic resin pipes together, the ends of the thermoplastic resin pipes are held in a slightly protruding state between a fixed clamp and a movable clamp, and the end faces of each thermoplastic resin pipe are chamfered. Thereafter, each tube end surface was pressed against a hot plate to heat and melt it, and then the molten tube end surfaces were butted together and welded and joined.
ところで、熱溶着する熱可塑性樹脂管がポリエチレン管
である場合には、ポリエチレン管は常温においても非常
に柔かいために外力によつて変形を受け易く、特に肉厚
が薄い管では本来の真円ではなく、偏平状に変形してい
る。By the way, when the thermoplastic resin pipe to be heat welded is a polyethylene pipe, the polyethylene pipe is very soft even at room temperature, so it is easily deformed by external force, and in particular, a pipe with a thin wall thickness may not be the original perfect circle. It is deformed into a flat shape.
従つて、このように偏平状に変形したポリエチレン管を
前記溶着装置に保持して接合する場合には、単に管をク
ランプに保持しただけではクランプの側面から突出した
管先端部は真円にならない。従つて、偏平状に変形した
管同志が突き合わせ接合される結果、必然的に管接合部
の内周面に段差が生じ、この部分に異物が詰まるという
問題があつた。また、これと同時に両方の管端面は偏心
した状態で接合されるために、両方の管端面が溶着する
実質的な接合面積が減少し、充分な接合強度が得られな
い。Therefore, when holding polyethylene pipes that have been deformed into a flat shape in this manner in the welding device and joining them, simply holding the pipes in the clamps will not make the ends of the pipes protruding from the sides of the clamps perfectly round. . Therefore, as a result of butt-joining the tubes that have been deformed into a flat shape, a step inevitably occurs on the inner circumferential surface of the tube joint, and there is a problem in that this portion becomes clogged with foreign matter. Moreover, since both tube end surfaces are joined in an eccentric state at the same time, the substantial joint area where both tube end surfaces are welded is reduced, and sufficient joint strength cannot be obtained.
従つて、この管接合部に振動・衝撃等が作用した際には
、この接合部に亀裂の生じることがあつた。更には、従
来のパット溶着装置は、移動クランプの移動・押圧操作
をエアシリンダー、あるいは油圧シリンダーの作動によ
つて行なつていたので、熱可塑性樹脂管の端面を熱板に
押付けて溶融する際、あるいは溶融した管端面同志を溶
着接合・する際に、管の径サイズに応じた適正な押圧力
の付与およびその微調整が難しいという問題があつた。Therefore, when vibrations, shocks, etc. are applied to this pipe joint, cracks may occur in this joint. Furthermore, in conventional pad welding equipment, the movable clamp was moved and pressed by operating an air cylinder or hydraulic cylinder, so when pressing the end face of the thermoplastic resin pipe against the hot plate to melt it, Alternatively, when welding and joining the molten tube end surfaces together, there is a problem in that it is difficult to apply an appropriate pressing force according to the diameter size of the tube and to finely adjust it.
しかも、移動クランプの作動機構をエアシリンダーある
いは油圧式にすると、装置全体の重量が増大し、持ち運
びに不便であるために現場での配管施工に不適であつた

保持した熱可塑性樹脂管の管外壁に押圧力を付与して管
先端部を真円に矯正する調整ボルトを設けて、それぞれ
の管の接合端面を真円、かつ同芯状に保持したまま溶着
接合できるようにしたものである。Furthermore, if the operating mechanism of the movable clamp is an air cylinder or hydraulic type, the weight of the entire device increases and is inconvenient to carry, making it unsuitable for on-site piping construction. The present invention solves all of the problems faced by such conventional devices at once, and consists of a fixed clamp and a movable clamp arranged in a straight line on a base plate, and these clamps have a thermoplastic An adjustment bolt is provided that applies pressing force to the outer wall of the resin pipe to correct the tip of the pipe to a perfect circle, making it possible to weld and join each pipe while keeping the joint end faces of each pipe perfectly circular and concentric. This is what I did.

It can apply an appropriate pressing force depending on the diameter size, and the entire device is lightweight so that it can be easily carried when constructing piping on site. The present invention provides a pad welding device equipped with a rotary chamfering machine and a hot plate.

In this way, after correcting the tube tips of the thermoplastic resin tubes 5, 5 held by each clamp into perfect circles, the movable clamp 3 is moved back, and a rotating surface is formed between the fixed clamp 2 and the movable clamp 3. Set the removal machine 6.

構44て固定する。Then, by rotating this rotary chamfering machine 6, both pipes 5, 5 are
Cut the pipe end face and chamfer the inner wall of the pipe end. After that,
The rotary chamfering machine 6 is removed, and a hot plate 7 is interposed between the fixed clamp 2 and the movable clamp 3. After fixing the lower part of the movable clamp 3 to the guide shaft 11, the torque wrench 41 is rotated to make the tube holding part of the movable clamp 3 protrude toward the fixed clamp 2 side, and each thermoplastic material is attached to both sides of the hot plate 7. It is brought into contact with the end surfaces of the resin pipes 5, 5. In this way, the torque wrench 41 is further moved from the state in which the hot plate 7 is in contact with the tube end surface.
While reading the pressing force of the torque wrench 41 on the torque display plate 42, a predetermined pressing force corresponding to the pipe diameter size is applied to the hot plate 7, and the elastic deformation of the torque wrench 41 is fixed by the locking mechanism 44.
熱可塑性樹脂管5の端面が熱板7に圧接して徐々に溶融
すると、この溶融樹脂は管端面の内外に押出される結果

押圧力で熱板7に圧接して溶融する。When the end face of the thermoplastic resin pipe 5 comes into pressure contact with the hot plate 7 and gradually melts, this molten resin is pushed in and out of the pipe end face, and as a result, the holding part of the movable clamp 3 moves somewhat toward the fixed clamp 2 side. Since elastic force is applied to the torque wrench 41, the thermoplastic resin tube 5 is pressed against the hot plate 7 with an appropriate pressing force that follows this movement and melts.
そこで、ロック機構44を解除すると共にトルクレンチ
41を逆方向に回動させて素早く熱板7を取り外す。Therefore, the locking mechanism 44 is released and the torque wrench 41 is rotated in the opposite direction to quickly remove the hot plate 7.

Press it against the end face with a specified pressing force. Of course, when joining these pipes together, the pressing force is applied while reading the pressing force of the torque wrench 41 on the torque display plate 42 in the same manner as described above, and this pressing force is maintained by the locking mechanism 44 for a predetermined time. do.
かくして、固定クランプ2と移動クランプ3とに保持し
た熱可塑性樹脂管5,5は、真円、かつ同芯状に溶着接

状に管同志を接続することができる。As described above, in the pad welding device of the present invention, the fixed clamp and the movable clamp are arranged in a straight line on the base plate, and each clamp is provided with an adjustment bolt, so that by simply rotating the adjustment bolt, The tips of the tubes held by the respective clamps can be corrected to a perfect circle, and the tubes can be connected in a perfect circle and concentrically.

単に行なえ、極めて強固な溶着接合が得られる。Moreover, the movable clamp is equipped with a torque wrench that moves it toward the fixed clamp and applies a pressing force, and a manual presser equipped with a locking mechanism to maintain this pressing force.
When press-welding tube ends to a hot plate or pressing molten tube ends together to butt-join them, it is possible to apply the optimal pressing force according to the diameter of the tube, and it is also easy to make fine adjustments. , an extremely strong welded joint can be obtained.

配管施工に極めて好適である。In addition, the device of the present invention has a simple structure because the movable clamp can be moved and pressed manually, and is much lighter than conventional air cylinder or hydraulic welding devices. It is convenient to carry and extremely suitable for on-site piping construction.
