(54) УСТРОЙСТВО ДЛЯ ОБРАБОТКИ ТОРЦОВ ПЛАСТМАССОВЫХ ТРУБ(54) DEVICE FOR TREATING THE END OF PLASTIC PIPES

1one

Изобретение относитс к обработке торцов пластмассовых труб перед их сваркой.This invention relates to the machining of the ends of plastic pipes before welding them.

Известен инструмент дл одновременной обработки торцов пластмассовых труб, содержащий два диска, снабженные рабочими ножами и жестко св занные с размещенным между дисками храповиком, руко тку, снабженную собачкой и установленную на оси 1 .A known tool for simultaneous machining of the ends of plastic pipes, comprising two disks, fitted with working knives and rigidly connected to a ratchet placed between the disks, a handle provided with a pawl and mounted on axis 1.

При работе на данном устройстве возникающа нагрузка направлена в одну сторону , в результате чего вс система становитс неустойчивой, что приводит к неудобствам работы оператора в монтажных услови х .When operating on this device, the resulting load is directed in one direction, as a result of which the entire system becomes unstable, which leads to inconveniences for the operator in the installation conditions.

Наиболее близким из известных вл етс устройство дл обработки торцов пластмассовых труб, содержащее смонтированную на раме приводную фрезу, выполненную в виде корпуса с установленными по обе его стороны двум дисками с рабочими ножами на наружной торцовой поверхности 2.The closest known is a device for processing the ends of plastic pipes containing a drive cutter mounted on a frame, made in the form of a housing with two disks mounted on both sides with working blades on the outer end surface 2.

Данное устройство также обладает неустойчивостью при обработке торцов труб и, следовательно, неудобно в обслуживании.This device also has the instability in the processing of the ends of the pipes and, therefore, inconvenient to maintain.

Цель изобретени - повышение удобства обслуживани .The purpose of the invention is to improve serviceability.

Поставленна цель достигаетс тем, что устройство дл обработки торцов труб, содержащее смонтированную на раме приводную фрезу, выполненную в виде корпуса с установленными по обе его стороны двум This goal is achieved by the fact that a device for processing the ends of pipes, containing a drive cutter mounted on the frame, made in the form of a body with two mounted on its both sides

5 дисками с рабочими ножами на наружной торцовой поверхности, снабжено шестерней, св занной с приводом фрезы и установленной между двум дисковыми ножами, выполненными с зубчатой нарезкой на внутренней торцовой поверхности, причем корпус выполнен с направл ющими качени , а дисковые ножи установлены на них с возможностью вращени в противоположные стороны .5 discs with working knives on the outer end surface, equipped with gear, connected to the cutter drive and installed between two circular knives, made with serrated cutting on the inner end surface, the casing being made with rolling rollers, and the circular knives are mounted on them with the possibility rotation in opposite directions.

На фиг. 1 изображено предлагаемое уст5 ройство дл торцовани , расположенное на направл ющих сварочного приспособлени ; на фиг. 2 - разрез А-А на фиг. 1; фиг. 3 - разрез Б-Б на фиг. 2; на фиг. 4 - разрез В-В на фиг. 3.FIG. 1 depicts the proposed tapering device located on the guides of the welding device; in fig. 2 shows section A-A in FIG. one; FIG. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3

Claims

20 The device comprises a welded body 1, provided with recesses 2 for covering guide shtangs 3 of welding fixture 4 and carrying a milling cutter 5, made in the form of two discs 6 and 7, located on both sides of body 1 and mounted on guide rails 8 rotation in opposite directions relative to each other. On the outer end surface of each disk 6 and 7 there are working knives 9 in such a way that on one of them the direction of sharpening knives 9 is opposite to the direction of sharpening knives on another surface. The disks 6 and 7 through the serrated 10 cut, made on their inner end surface, are kinematically connected with the bristles 11 placed in the housing 12 and mounted on the output shaft of the drive 13, which can be made mechanically or manually. On the guide pins 3, the fixed 14 and movable 15 clamp clamps are installed, c. which have welded pipes. The movement of the movable yoke 15 is carried out from the hydraulic cylinders 16 placed inside the guide shtang 3. The device operates as follows. The pipes to be welded are placed in clamp clips 14, 15 and fastened. The milling cutter 5 is nested with recesses 2 centered on the guide bar 3. With the help of hydraulic cylinders 16, with a constant force, the movable collar 15 presses the end of one welded pipe against the milling cutter 5, which in turn presses against the end of another welded pipe. The actuator 13 is turned on, the rotation from which is received by the brush 11, which drives the disks 6 and 7 through the gear cut 10 into rotation, the rotation of which is opposite to each other. As a result of the rotation of the discs 6 and 7 9, 37. The knives 9 are facing two ends of the welded pipes simultaneously. At the time of processing the pipe ends, the entire system (welding fixture 4, mill 5) remains stable, since the lines of action of the cutting forces are directed in opposite directions. The use of the present invention allows for easier maintenance and also reduces the size and weight of the structure as a result of decomposing the load in opposite directions. The invention of the device for processing the ends of plastic pipes, contains a drive cutter mounted on the frame, made in the form of a housing with two disks mounted on both its sides with working blades on the outer end surface, characterized in that the device is equipped with gear to increase serviceability. associated with the cutter drive and installed between two circular knives, made with serrated cutting on the inner end surface, the casing being designed with rolling guides And circular knives mounted on them rotatably in opposite directions.
