Description

Изобретение относитс к области машиностроени , в частности к конструкции машин дл гибки труб.The invention relates to the field of mechanical engineering, in particular, to the design of pipe bending machines.

Известно устройство ij дл многоколевной гибки труб по замкнутому контуру, соде жащее смонтированные на станине поворотные планшайбы с копирами и гибочными элементами .It is known a device ij for multi-bending pipe bending along a closed contour, containing rotating faceplates with copiers and bending elements mounted on the frame.

Недостатком известного устройства вл етс низка производительность.A disadvantage of the known device is low productivity.

С целью повышени производительности кажда планшайба снабжена двум приводными ползунами, размешенными в радиальных направл ющих планшайбы, при этом копир установлен на одном ползуне, а гибочный эл&мент - на другом, кажда планшайба снабжена упором, взаимодействующим с ползуном, несущим копир, а привод ползунов выполнен в виде вала с шестерней, смонтированного вдоль оси каждой планшайбы, и наход щихс в запеплении с шестерней реек, закрепленных на ползунах.In order to increase productivity, each faceplate is equipped with two drive sliders placed in the radial faceplate guides, with the copier mounted on one slide and the bending electric amp on the other, each faceplate provided with an abutment interacting with the slide bearing the copier, and the drive of the sliders made in the form of a shaft with a gear wheel mounted along the axis of each faceplate and being in heat with a gear wheel of the rails attached to the sliders.

На фиг. 1 показана схема размещени планшайб с копирами и гибочными элементами; на фиг, 2 - реечный привод ползунов; FIG. Figure 1 shows the layout of the faceplates with copiers and bending elements; in Fig, 2 - slatted drive sliders;

Устройство содержит четыре планшайбы 1 установленные на роликовых подшипниках Б корпусе 2 и на приводном валу 3. Устройство вертикального типа (оси планшайб горизонтальны ). В направл ющих каждой планшайбы размещен ползун 4, несущий копир 5, и ползун 6 с гибочным роликом 7. На верхних планшайбах вместо гибочных роликов установлены гибочные сухари 8 на ос х 9. Подъем и опускание сухарей осуществл етс с помощью пазов 10. Б исходном положении ползуны 4 копиров 5 установлены диагонально внутри четырехугольника, образованного ос ми 9 планшайб, а гибочные ролики 7 на своих ползунах 6 установлены с внешней стороны этого четырехугольника и развернуты так, что лини их пр мого и обратного движени образует угол 135 с направлением указанного движени ползунов 4 копиров.The device contains four faceplates 1 mounted on roller bearings B of the housing 2 and on the drive shaft 3. The device is of a vertical type (the axes of the faceplates are horizontal). In the guides of each faceplate, a slider 4 is placed, carrying a copier 5, and a slider 6 with a bending roller 7. On the top faceplates, instead of the bending rollers, there are bending crackers 8 on the axes 9. The raising and lowering of the crackers is carried out using the slots 10. B The sliders 4 of the copiers 5 are installed diagonally inside the quadrilateral formed by the axes 9 of the faceplates, and the bending rollers 7 on their sliders 6 are installed on the outer side of this quadrangle and are turned so that their forward and reverse movement lines form an angle of 135 seconds. leniem said movement of the slide 4 copiers.

Claims

The sliders 4 and 6 are equipped with rails 11 and 12, respectively, coupled with the common gear 13, rigidly seated on the drive shaft 3 of the faceplate. Fill up this shaft; :: at the other end with gear 14, which is driven by the rail 15 and the pneumatic piston rod. The supports 16 are designed to accommodate the workpiece. The cycle control is carried out using the limit switch 17 and the stop 1. The device operates as follows. The pipe is installed with a longitudinal restriction on the supports 16. The stroke of the lower pneumatic cylinders is switched, the slats 15 turn into rotation, turning the lower right shaft 3 counterclockwise, and the left one clockwise (see fig. 1). At this time, the upper y & ly still. When the shafts 3 rotate, the gears 13 drive the sliders 4 and 6 into approach, and the faceplates 1 do not rotate c. When the copiers 5 and the bending rollers 7 descend and clamp pipe 19 into the stream, and along the zuna 4, they are pressed into the face plates 18, the axes of the copiers 5 coincide with the axis of rotation of the smooth washers. Then, the rotation of the bottom plates 1 begins with the coiled tubing and the formation of two lower bends on it. During the rotation of the faceplates, the cam 5 remains stationary, since they are mounted pivotally. This eliminates the slippage of the pipe relative to the copiers. The final position of the faceplate at the end of the bend is shown in FIG. 2 (faceplate rights), where the holder of the bending roller 7 reached the stop 18 and turned around the axis, freeing the bent branch in an adjustable position. When stopping the faceplate, the bent branches are placed on the top faceplates, and the movable structural elements are in their original position. At the upper smooth washers instead of bending rollers there are bending crackers 8, pubescent along groove 10 to the initial position. This position is necessary in order to allow the bent branches to enter the streams of the copiers 5 with a slight bend provided by distant copiers 5. The crackers are raised along the grooves 10. The movement and operation of the other elements of the upper faceplates does not differ from the movement of the elements of the lower faceplates. After the formation of all four bends, the return stroke is engaged, and all parts return to their original position. Claim 1. A device for multi-column pipe bending in a closed loop, containing frame-mounted pivoting plate with copiers and bending elements, characterized in that, in order to improve performance, each faceplate is equipped with two drive sliders placed in radial guide plates. The copier is mounted on one slider, and the bending element is on the other.

2. The device according to claim 1, characterized in that each faceplate is provided with an abutment interacting with a slider carrying a copier.

3. Device pop, 1, characterized in that the drive of the sliders is mounted in the form of a shaft with a gear wheel mounted along the axis of each faceplate, and meshes with the gear of the rails attached to the sliders.
