RS20100459A2 - Mechanism for bending diagonal wire of lattice girder - binor - Google Patents

Abstract

Invention herewith described refers to the mechanism for bending diagonal wire of the lattice girder – binor consisting of two identical chain transmissions (1) and (2), whereat the lower chain transmission (1) is located under the upper chain transmission (2).On the transmission (1) chain and the transmission (2) chain there is set the same number of girder assemblies (17) with the tools (18) mounted on them.The transmission (1) chain is mounted on the chain pulley (13), and through the girder assembly (17) on the lower outer curve (9) and the lower inner curve (11).The transmission (2) chain is mounted on the chain pulley (14), and through the girder assembly (17) it is mounted on the upper outer curve (10) and the upper inner curve (12).On each girder (17) there is mounted one roller bearing (20).On each pin (16) of the chain plates (15) there are mounted two roller bearings (19) and two sleeves (37), with the pin (16) passing through the openings (30) on the girder (17). The girder (17) can partially swivel around the pin (16).The girder (17) is through springs (21) connected with plates (15) of the chain and constantly rests through the roller bearing (20) on the inner curve (11, 12), and through the roller bearings (19) on the two outer curves (9, 10). Rolling of the roller bearings (20) along the outer curves (9, 10) lasts for only one part of the revolution, and the rolling of the roller bearings (19) along the inner curves (11.12) is performed continuously.The chain transmissions (1) and (2) are mutually rotated at a certain small angle of 36 minutes.The chain transmissions (1) and (2) with tools (18) draw wire (43), which passing between them comes out with formed wave of the appropriate height (H) and the pace (C).
