Description

heat 8 with gear 9 and cardan shaft 10,

The same mechanism consists of a locking head 11, including the upper 12 and lower 13 pairs of rollers, which are respectively placed on Tpaeeijce 14 and in the housing of the rejector 15, which is connected by means of the coupling 16 with electric movement 17. The pressing force of the rollers to each other is adjusted by a nut 18 through a cup plate 19.

For the width of the mounting apertures 20, the runs 21 are performed without the side elements. The forming mechanism is installed in the mounting aperture and le is movable and the acre is pl-fixed with locking screws 22 on the girders of the girders opposite the boron elements. Comrade

The described device works as follows.,. 20

The end of the rolled tape 23 winds up the rollers of the forming Mexai-Shzma from the unwinding device using a winch or a crane. Then, an electric motor is switched on, which, through a reducer and a cardan shaft 35, leads into D1Zhzhenie forming head rollers ..

Submerged rollers pull the tape and subsequently form its longitudinal edges according to the configurations shown in .30 in FIG. 7, with an output profile corresponding to the outer contour of the side Run Elements.

Formed tape edges at the exit of the forming head are mounted on the side elements of the girders and slide along them to the opposite mounting opening. The length of the tape along the runs is cut to size, after which the forming mechanism is removed, the tensioning device 40 is installed and the tape is tightened. Analogously, metal tapes are attached to the enclosing claws on all subsequent spans. The final fastening of the ribbons on the girders is carried out by the fixing fur-45 low. This occurs when, with an increase in the gap between the upper and lower pairs of rollers, by loosening the cup springs and pressing the locking knob, the locking head is mounted on the flange elements of one and three passes through the mounting opening.

By turning on the electric motor, a clutch, a gearbox and rollers are driven. In this case, the locking mechanism, moving along the run, rolls the longitudinal edges of the tape around the side elements of the runner with rollers. At the exit of the purlins, the locking mechanism is removed through the mounting opening. In order to increase the adhesion of the chrome strip to the bead elements of the purlins, the working surfaces of the rollers are corrugated.

Due to the implementation of the device in the form of a forming and fixing mechanisms when performing the first in the form of a fixed frame and mirror-like forming heads fixed to kw, and the second P01 in the form of a movable traverse and fixing head fixed on it, the corresponding metal mechanization and productivity can be improved accordingly. the bearing and tape protecting designs. The completion of the (mixing head in the form of upper and lower pairs of interconnected between, driven, spring-loaded rollers, respectively, placed on the frame and grass, allows for a further increase in mechanization and productivity; as well as improve safety of working conditions.

Claims (2)

1. A device for connecting metal elements of shusch and tape enclosing structures, including forming and locking mechanisms, from l and c w with the fact that, in order to increase mechanization and productivity, the forming mechanism is made in the form of a fixed frame and two mirrored forming heads attached to it, and the locking mechanism is made in the form of a movable crosshead and ({{xxiksuyuschey head, hardened to shy. -::;, 2. The device according to claim 1, in which the forming and fi ching heads are EXTENDED in the form of upper and lower pairs of interconnected drive sub-rollers, respectively, placed on the frame and traverse.  7y 7 / x i / XX7X /.
