DEVICE FOR PRELIMINARY ASSEMBLY AND WELDING OF PIPELINE PIPELINES IN PIPELINES

摘要

The utility model relates to the field of pipe welding, namely to devices for assembling for welding of steeply curved stamped welded branches of pipelines from thick plates in the form of radius gutters / shells (hereinafter referred to as "elements") and then welding them into a finished stamped product. The device comprises a support-centering unit in the form of an annular frame 1. In the rim 2 of the frame, the edge gripping clips 3 are mounted at the joint of the retraction elements, which ensure a symmetrical application of a large force to the tap. At the base of the frame, assembled monolithically with it, the guides 5 in which the carriage 7 moves on the rollers 6 with the rotation drive 8 of the C-shaped platform 9. The platform on the roller bearings 10 can be rotated radially relative to the axis of the rotation drive shaft 8 separately from the frame , not touching it. On the shaft 11, the slide 13 is slidably slidable in the rails 14 of the ruler 15. Along the rails 14 in the ruler 15, the base holes 16 are provided for fixing the slider 13 with the pin 17 for transferring the torque to the platform 9 and changing the axis of the drive shaft. The base holes are made along the guide rulers and represent the scale of the sizes of the diameters of the machined elbows. The carriage 7 is connected to the hydraulic cylinder 19 of its positioning by means of its position sensors 20 relative to the base holes in the guide rails 15. To receive and fix the retraction elements, the platform 9 is provided with a package of radial support trays 22 stacked in pyramid 21. 3 il. Along the guides 14 in the ruler 15, the base holes 16 are provided for fixing the slider 13 with the pin 17 for transferring the torque to the platform 9 and changing the axis of the drive shaft. The base holes are made along the guide rulers and represent the scale of the sizes of the diameters of the machined elbows. The carriage 7 is connected to the hydraulic cylinder 19 of its positioning by means of its position sensors 20 relative to the base holes in the guide rails 15.
