AI Technical Summary
Existing profiling machines require high-precision metal-intensive spacers for adjusting forming rollers, leading to increased production costs, metal consumption, and prolonged setup times due to the need for dismantling and reassembly of roll forming stands.
Utilizing neodymium magnets to set and secure the required distances between forming rollers on profiling shafts, eliminating the need for high-precision spacers by fixing the rollers with clamping screws after positioning them with magnets.
Reduces metal consumption, saves time in adjusting profiling stands, and simplifies the readjustment process by eliminating the need for high-precision spacers, thereby reducing production costs and setup time.

Abstract
Description
[0001] The present invention relates to the field of metal forming, namely to the profiling of cold-rolled sheet metal, including those with coatings, from a flat metal strip passing sequentially through a series of profiling stands, with the formation of a given profile, and can be used to install forming rollers in the profiling stands of a profiling machine during its manufacture and setup.
[0002] A combined profile bending machine is known (see https: / / profileqibzavod.ru / catalog / line-profilirovanva / stan-profileqibochnvi-kombinirovannvi / ), in which the forming rolls are separated from each other by spacer bushings.
[0003] Also known is a universal roll forming mill stand (see Russian Patent No. 2231409), in which the roll forming stand shafts are equipped with limiting flanges. A threaded spacer sleeve is positioned between the limiting flange and the forming roller with a disc-shaped clamping nut.
[0004] A profile bending machine is also known (see Russian Patent No. 2254193), in which the working shafts of the roll forming stands are equipped with base flanges. Bushings of a predetermined size are positioned between the base flange and the forming roller. Each roller pair has a base plane resting against the bushing.
[0005] From the prior art, the works of the company “Engineering Center “AMTengineering” of equipment” are also known, for example, the article “Equipment for working with sheet material” (see https: / / www.amtengine.com / ), which mentions that the rolling rolls are made as prefabricated ones, consisting of working shafts and forming rollers and spacer rings fixed to them.
[0006] In all the above examples, the spacers are precision-machined with ground ends and must be of varying sizes to match the position of the forming rollers on the roll shaft relative to the base flange. In some cases, the spacers are threaded. Storage space for the spacers is required. When changing the stands, it is necessary to dismantle the roll shaft, remove the spacers, and reassemble the new configuration. All this leads to additional production costs, significant metal consumption, increased equipment costs, and lost time during the manufacture and setup of the roll forming stands.
[0007] The subject of this technical solution is a method for installing forming rollers in a profiling machine.
[0008] The technical result of the claimed invention consists in saving metal, reducing the time for readjusting the profiling stands, eliminating the need for high-precision metal-intensive spacers, and making it easy to readjust the profiling shafts.
[0009] The specified technical result is achieved by the fact that a method is proposed for installing forming rollers in a profiling machine containing profiling stands, each of which contains a shaft, a base in the form of a ring fixed on the shaft and forming rollers, wherein the required distance from the base to the nearest forming roller is set by a set of neodymium magnets tightly located on the shaft from the edge of the base to the end of the forming roller, and the distance to the next forming roller from the previous one is set each time also by a set of neodymium magnets tightly located on the shaft between the ends of adjacent forming rollers.
[0010] Fig. 1 shows a front view of the profiling shaft.
[0011] In the proposed method for installing forming rollers 1 in a profiling machine containing profiling stands 2, each of which contains a shaft 3, a base 4 in the form of a ring fixed on the shaft 3 and forming rollers 1, the required distance L1 from the base 4 to the nearest forming roller 1 is set by a set of neodymium magnets 5, tightly located on the shaft 3 from the edge of the base 4 to the end of the forming roller 1, and the distance L2 to the next forming roller 1 from the previous one is set each time also by a set of neodymium magnets 5, tightly located on the shaft 3 between the ends of the adjacent forming rollers 1.
[0012] Fig. 1 shows a profiling shaft 3 with a base 4 in the form of a fixed ring, which is installed between the walls 6 of the profiling stand 2. In order to achieve the required distance L1 between the base 4 and the end of the forming roller 1, neodymium magnets 5 of the required size are installed on the shaft 3 close to each other, the end of the forming roller 1 is pressed against the magnets 5 and fixed on the shaft 3 with clamping screws 7. In order to achieve the required distance L2 between the end of the previous forming roller 1 and the next forming roller 1, neodymium magnets 5 of the required size are also installed on the shaft 3 close to each other, the end of the next forming roller 1 is pressed against the magnets 5 and fixed on the shaft 3 with clamping screws 7.
[0013] Neodymium magnets 5 in the shape of a parallelepiped are produced in a wide variety of sizes, allowing the forming rollers 1 to be installed in the required positions on the shaft 3 with a multiple of 1 mm.
[0014] The proposed method of installing forming rollers 1 reduces the time for readjusting profiling stands 2 without dismantling the shafts, ensures significant metal savings, leads to the abandonment of high-precision metal-intensive spacers, and ensures ease of readjustment of the profiling shafts.
