Perforated bent nrofiles and a line for their manufacture

Alexey Nikolaevich

The group of useful models relates to the field of pressure processing, namely to the production of bent profiles, as well as to the construction field.

Known bent profiles obtained by sequentially forming a metal billet - strip - in the rolls of a roll forming mill (RF Patent No. 2137566). The disadvantage is their large metal consumption, weight and, accordingly, high cost.

Also known are perforated bent profiles made in the form of a structure formed from a strip billet in the rolls of a roll-forming mill to produce perforations (holes) before profiling on a smooth, continuous surface of the billet or directly on the profile (Product Catalog of ZAO Arkada, Smolensk, 2001).

The disadvantage is the additional consumption of material - the initial workpiece and a decrease in productivity in the manufacture of perforation.

A known line for stamping flat washers from a strip of metal billets, including a feed device for the strip, a stamping device and a packaging device (namuyatel) for waste in the form of a perforated tape ("Guide to cold stamping).

The disadvantage is the presence of irretrievable waste and significant efforts and funds for their further processing or disposal as scrap metal.

The essence of the utility model.

In the manufacture of flat metal washers, metal waste is about 50% in the form of a calibrated perforated tape.

The field of technology.

The prior art.

spatial systems and are used as building structures, frames, various kinds of fences. Their widespread use is possible as light and cheap beacons in the production of any plastering work.

Perforated bent joints have holes (perforations) not less than the total surface area of the original continuous workpiece (strip), and the edges of the profiles are made with the possibility of the formation of a lock connection of two or more structures that make up a common rigid system.

The implementation of the perforation blank exceeding its surface significantly reduces the weight of the bent profile. This ratio of perforation contributes to improving the quality of adhesion of the mortar during construction and plastering, reducing the complexity and cost in comparison with other known analogues. In this case, the profiles remain under a layer of plaster. A system of several bent profiles connected to a lock provides the necessary rigidity for the design of beacons, frames, fences, greenhouses, greenhouses, etc.

The line for the manufacture of perforated bent profiles consists of a device feeding a strip billet, a roll forming mill, and a baling device. At the same time, a stamping device is installed in front of the bending mill, which operates in a synchronous speed mode for the manufacture of stamped parts, and stamping waste is disposed of in the form of a perforated strip, which in turn is used as a blank for the manufacture of bent profiles with a lock connection. Recycling of stamping wastes, which consists in using them by profiling, provides an additional technical result for eliminating the irretrievable losses of metal and the costs of their storage, transportation, processing.
