Abstract

The invention relates to the processing of metals by pressure and can be used in shipbuilding to form zigos on tube blanks in the manufacture and repair of pipelines. The goal is to expand the technological capabilities of the device by ensuring that zigs are carried out both outside and inside the tube blanks. For this, the device is provided with a threaded bar along its entire length, a rod with removable stops, a pair of additional holders with two openings for installation with the possibility of movement on the rod and the rod, and a mechanism for adjusting the distance between the support rollers. Each additional holder is rigidly connected to a support roller and spaced inside the shaped pipe to form an internal ridge or outside to form an external ridge. The rod is rotated around the billet, periodically pressing the forming rollers with nuts to the inner or outer surface until a high-quality ridge is obtained. 2 Il.

The invention relates to the processing of metals by pressure and can be used in shipbuilding to form seals on tubular blanks in the manufacture and repair of pipelines.

The aim of the invention is to expand the technological capabilities of the device by ensuring that the zigos are executed both outside and inside the tube blanks.

Easy device assembly, its fast

FIG. 1 shows the device, the type of installation and removal from the pipe is allowed in the plan; in fig. 2 - the same, - front view. increase the productivity of the device contains two pairs of zigovka-holding operations as compared to the limestones 1 installed on the rod 2. Bottom devices of the same designation are rigidly attached to the holders 1, in addition, the ability to quickly change an example welded, perpendicular to the axis of the holders provides expansion of the technological rod 2, axis 3 is molded, their rollers 4 logical capabilities of the device by

making zigov both outside the billet and inside with a single device, and the ability to adjust the distance between the holders by means of nuts made with smooth holes under JQ allows drying the pipe zigovka razstrugu 2 and erased 6. At the bar 2 personal diameters and thicknesses; nuts 7 are placed, forming 2 threaded joints with the rod. At the ends, the rod 2 is provided with removable handles 8, and the rod 6 with removable stops 9 (limiters). Nuts 7 on the rod 2 accommodate 25 pipes containing rigidly mounted on

and support rollers 5. The holders 1 are interconnected by a fixing rod 6. The rod 2 is threaded along the entire length, and the rod 6 is smooth. Holders

Claims (1)

Claims Portable Zigzag Device so that between the two nuts 7 there are two holders 1 with a forming roller 4 and a supporting roller 5. The device works as follows. Tube blank 10 is mounted in a vice holders a pair of forming rollers and a pair of support rollers, made with protrusions and depressions, and the mechanism for adjusting the distance between the support rollers, made in the form of threaded connections. or on the tube clamp (not shown). 30 characterized in that, with the aim of expanding the bar 2, two pressure nuts 7 are put on so that they fit inside the pipe 10, then the holders 1 are installed in pairs on the bar 2 so that the forming rollers 4 with protrusions are stirred neither technological capabilities due to ensuring the application of internal and external zigov, it is equipped with a threaded bar along the entire length, a rod with removable stops, installed parallel to the inside of the pipe 10, and supporting rollers 5 with a 35, double pair of holders with outside the pipe 10. Then again with the holes for installation two nuts 7 can be knocked out and the handles 8 are screwed onto the ends of the rod 2. in holders 2 there is a rod 6, on The axial movement on the rod and rod, each additional holder rigidly connected to the support, which has 9 stops are put on. By means of a face, in each existing holder, by means of nuts 7 of the holder 1, the holes for the shaft are approached the walls of the pipe blank, 10 so that the rollers 4 and 5 come in contact with them. Holding the handles 8, vrash, aU1 bar around the pipe billet 10, and a rod, and the mechanism for adjusting the distance between the support rollers is made in the form of fixing nuts placed on the shtanga with the possibility of intermittently pressing the forming rollers 45 of the cable with additional holders. 4 nuts 7 to the inner or outer surface to obtain a high-quality ridge. At the end of the zigovka, the nuts 7 are retracted from the holders 1, the arms 8 are removed from the rod 2, the stops 9 are removed from the rod 6, the device is ready for shifting the rollers 4 and 5, or freely removed from the pipe 10. Easy device assembly, its fast installation and removal from the pipe allows an increase in labor productivity in the zigzag operations compared with the known devices of the same designation; in addition, the ability to quickly change holders provides an expansion of the technological capabilities of the device by The zigov fillings both outside the pipe runs and inside with one device, the ability to control the distance between the holders by means of nuts will dry out the fixing of pipes of different diameters and thicknesses, b, which are rigidly mounted on Claims Portable Zigzag Device making zigov both outside the billet and inside with a single device, and the ability to adjust the distance between the holders by means of nuts allows drying of pipes of various diameters and thicknesses, pipes containing rigidly mounted on holders a pair of forming rollers and a pair of support rollers, made with protrusions and depressions, and the mechanism for adjusting the distance between the support rollers, made in the form of threaded connections.  characterized in that, in order to expand the technological capabilities by ensuring the application of internal and external zigos, it is equipped with a threaded bar along the entire length, a rod with removable stops installed parallel to the pants, a pair of additional holders with two holes Possibility of a rod, and the mechanism for adjusting the distance between the support rollers is made in the form of fixing nuts placed on a bar with the possibility of interaction Phi.1
