Definitions
- the invention relates to the field of mechanical engineering and, in particular, to devices for mechanical processing of pipes by pressure and can be used when winding heat exchange pipes for NPP heat exchangers into a coil with specified parameters (winding diameter and pitch).
- Close-packed heat exchangers are widely used in the designs of nuclear power plants, where the main problem is the low uniformity and density of the winding.
- the main disadvantage of the known devices and devices for bending pipes is that in the process of bending the cross section of the pipe is strongly deformed, the wall thickness on the outside is 1
- SUBSTITUTE SHEET (RULE 26) (larger radius) decreases, and from the inside (smaller radius) it increases, and in this case, for thin-walled pipes, the formation of wavy folds also occurs.
- the closest in technical essence to the claimed solution is a device for winding metal pipes into a coil, which is equipped with three rollers, the lower of which are made of two strands with a separating flange that determines the pitch and angle of the winding (patent for the invention of the Russian Federation No. 2221666, IPC B21D 53/06 , published on January 20, 2004).
- the main disadvantage of this device is that the winding of pipes on a lathe is carried out with a constant force and leads to a non-circular section, and the winding of thin-walled pipes is practically impossible, as well as low winding productivity.
- the technical problem of the present invention is to increase the productivity of winding by batch winding of metal pipes into a coil with specified parameters while excluding deformation of their cross section.
- SUBSTITUTE SHEET (RULE 26) the possibility of vertical movement by means of sliders and adjusting screws.
- the device is made with the possibility of simultaneous winding of metal pipes, the maximum number of which is equal to eight.
- the design of the proposed tension device for winding metal pipes into a coil is caused by operational practice, namely, that all known devices and installations for bending metal pipes, and even more so winding metal pipes into coils, have a clear drawback, which is that when bending or winding metal, especially thin-walled pipes, there is a deformation of the pipe in general and, most importantly, deformation of the cross section.
- the same tensioner for winding metal pipes into a coil thanks to rollers made of multi-strands with a mechanism that determines the pitch and angle of the winding, allows winding with the specified parameters while excluding deformation of their cross section with a significant increase in winding productivity.
- the maximum number of simultaneously coiled pipes equal to eight corresponds to the maximum possible number of strands in the roll roller. This parameter was determined experimentally when winding thin-walled pipes less than 1000 mm.
- FIG. 1 shows rolls with rollers.
- the tensioner for winding metal pipes into a coil consists of a support 1 (Fig.1) in the bracket of which, on the axis 2 (Fig.3), necessary to raise the tensioner when installing pipes, a housing 3 (Fig.1) is fixed with a mounted in it on tapered bearings 4 (figure 2) multi-strand removable rollers 5.6 (figure 1).
- the axes of the lower rollers are fixed permanently, the axis of the upper roller 6 is mounted in sliders 7, which, with the help of screws 8, have the ability to move vertically.
- Tensioner for winding metal pipes into a coil works as follows.
- the control unit (not shown in the drawings) is mounted in the caliper body and is designed to automate the process of winding tubes of coiled heat exchangers and implements the principle of coordinated control of the longitudinal movement of the device caliper depending on the angular displacement of the spindle shaft at a given winding pitch.
- the control is carried out by an industrial controller that reads information from the spindle shaft speed sensor. The received information is sent to the control rectifier, which maintains the optimum rotation speed of the caliper motor.
- Tensioning device for winding metal pipes into a coil allows you to expand the technological capabilities of the device and wind heat exchangers with a diameter of up to 2800 mm
- the proposed device allows to obtain close-packed bundles of pipes with different diameters and thicknesses and significantly increase the winding performance by 1.8-2 times.
