Description

The utility model relates to the processing of metals by pressure and can be used to bend strips with profiled edges used in roofing in industrial and individual construction, for example, in the construction of hangars or similar arched (cylindrical) structures.

A device for bending sheet blanks is known, described in USSR author's certificate No. 394128 "Machine for bending sheet blanks" published on 08/22/1973, containing a bed, feed rolls, a bending roll and a mechanism for supporting the curved portion of the blank made in the form of a lever system.

The disadvantage of this device is that it provides only one operation - bending sheets of a certain radius of curvature. When constructing arch structures, this is not enough, the sheets should have profiled edges to give the structure stiffness and for subsequent joining them using a fold connection.

There is also known a device for bending sheet material, described in USSR author's certificate No. 516461 "Device for bending" published on 06/05/1976, containing a bending machine with a bed, setting and receiving roller tables, a frame with rollers, made sectional.

The disadvantage of this device is that the device has the same drawback as the previous analogue, the device provides the ability to perform only one operation - bending sheets without first profiling their edges.

A device for profiling the edges of a strip or tape is described in the description of the patent of Russia No. 2177850, published January 10, 2002, 2002. The device comprises a frame, shafts installed in bearings that are mounted on the frame. On the shafts pairwise fixed left and right, profiling rollers of different shapes to obtain different profiled edges: left and right. The rollers are mounted with the possibility of changing the distance between them for profiling strips of different widths.

However, the described device allows to obtain a straight strip with profiled edges from a straight or roll strip. To obtain a curved, radial surface, you must also have equipment for bending, which is not in the device.

The device for bending strips contains a device for profiling edges (device for flanging edges ), which in turn contains a bed (rolling mill), shafts installed in bearings mounted on the bed, profiled rollers (flanging rollers) having different shapes are placed in pairs on the left and right, which о allows you to get different left and right flanged edges with their subsequent docking using a fold connection. For profiling strips of different widths, pairs of profiling rollers are fixed on the shafts with the possibility of changing the distance between them and fixing it. On the bed, from the side of the strip exit from the profiling device, mounted attachments for radial bending of the strip, consisting of a frame with left and right brackets, made in the form of pivotally and sequentially connected to the bed and between themselves levers with supports, while identical on pairs of levers are fixed radius forming rollers, each on a separate shaft, with the possibility of independently adjusting their position in the vertical plane using the left and right bearings and interacting with profiled cro kami (elements) to obtain a strip of the cylindrical surface.
