    The invention relates to the manufacture of welded pipes, in particular to devices for the manufacture of tubular blanks for welding. The known bending machine for the manufacture of tubular blanks of infinite length from a strip material, containing successively mounted on the frame, interchangeable cassettes with arched and rigidly fixed in bearings rows of convex AND: concave rollers forming a gauge with a gradually decreasing radius of curvature, while the length of each row of rollers corresponds to the width of the strip material for pipes of maximum diameter, manufactured on this machine ClJ The disadvantages of this device are low productivity This is due to the time spent on changing the machine to another size of manufactured pipes and the need for a large number of CMeiHoro tools. The purpose of the invention is to increase productivity by reducing the time for changeover. This goal is achieved by the fact that in a bending machine for the manufacture of tubular blanks containing interchangeably mounted cassettes mounted on a frame with arcuate and rigidly fixed in bearings rows of convex and concave rollers forming a gauge with a gradually decreasing radius of curvature, and the length of each row of rollers corresponds to the width of the strip material for pipes of maximum diameter manufactured on this machine, each cassette is made in the form of a plate with a slot for strip material, and The bending machines are equipped with a cassette holder with an additional set of interchangeable cassettes installed parallel to the frame with the possibility of longitudinal movement. Fig. 1 depicts the proposed bending machine for making tubular blanks, a general view; in fig. 2 - section of the bending machine (on an enlarged scale); in fig. 3 is a section A-A in FIG. 2 (with a strip material for pipes of maximum diameter), in FIG. 4, section A-A in FIG. 2 (with a strip material for pipes of minimum diameter); in fig. 5 is a view B in FIG. 2 (on a larger scale); in fig. 6 shows a section B-B in FIG. 5. A bending machine for manufacturing tubular blanks contains a roll cage 1 sequentially installed, a stand 2 with interchangeable cassettes 3 installed on it, a cutting cage A, a pipe welding machine 5 and a calibrating cage 6 Parallel to the styine with the possibility of longitudinal movement along the guides 7 the cassette holder 8 is mounted with an additional set of interchangeable cassettes 3. i Each cassette is made in the form of a plate with a slot under the strip material 9 and is arcuately and rigidly fixed in bearings with 10 rows of convex 11 and shoulder Uty 12 clips forming caliber. Concave rollers are located on the peripheral sides of the slot. The bearings have a lot of holing shape and are fixed on the cassette with the help of bolts 13. The rollers are mounted in bearings with the help of axles 14. Concave rollers are placed on both sides of the cassette. The bending machine works as follows. The strip material that is wound from a roll enters the roller stand and then into the cassettes, where they get the shape of a tubular blank. Then, the resulting tubular blanks are cut to length, welded and calibrated. When changing the bending machine to another tube size, the cassette from the base moves into the cells of the cassette holder, the latter moves along the guide rails to the right or left depending on the diameter of the pipes produced and the cassettes from the cassette holder are installed in the base with: appropriate parameters of the bending tool. The use of the invention will speed up the changeover of the bending machine to another size of tubular blanks and, thereby, increase productivity, as well as reduce the number of working tools for one machine.
