Description

The invention relates to the field of profile processing, in particular, to the construction of devices for unwinding rectangular waveguides.

The purpose of the invention is to improve the quality of the unwinding profile. ,

FIG. 1 shows the proposed device, general view; in fig. 2 - view A to FIG. one; pas figs. 3 shows a section BB in FIG. one; in fig. 4 - node I to fig. one; in fig. 5 is a view of B in FIG. four; in fig. 6 - section G-Y in FIG. four; in fig. 7 - node II of PA of FIG. one; in fig. 8 is a view of D in FIG. 7; in fig. 9 is a section E - E of FIG. 7; in fig. 10 - section MF on FIG. eight; in fig. 11 is a view of FIG. AND).

The device consists of a frame 1, the sides of which are connected by straps 2. To ensure lateral rigidity, frame 1 is equipped with pivot bearings 3, sharpenedly articulated with frame 1. On frame 1 there is a slot 4 for the rolling pin 5 of the cassette, and along edge of frame 1 guides 6 and 7 are mounted along which the rollers 8 (with horizontal or vertical unwinding) of the carriage 9 of the correct rollers 10 and 11 are moving.

directed toward the unwinding and protrude beyond, for example, the guides 6 of frame 1 by 200-300 mm.

The carrier carriage 9 of the block of the correct rollers 10 is installed under the unwinding-. turn of the waveguide so that the rollers 8 engage with the guides 6.

With the carriage 9 with rollers 11, the pushing yoke 12 is fastened so that the end 24 of the coil is between the yoke 12 and the carriage 9.

Applying a pulling force to the end of the outer turn 24, the waveguide is unwound. In this case, the passage through the correct rollers 10 and 11, the waveguide is straightened out - 15 minutes. With a decrease in the bay radius, the block of the correct rollers 10 and 11 moves along the guides 6 perpendicular to the direction of unwinding and at the same time turns towards the pulling force.

With the vertical unwinding of the waveguide, the block of correct rollers is installed on the guide 7, and the bay cartridge is rotated 180 °.

The remaining operations are similar.

Using the proposed device

The rollers 10 are mounted on the carriage 9, and the ro-25 can be unwound the bay with a waveguide length 35

Fig. 11 - on removable push-on pad 2. It was fastened to the carriage 9 with the help of fingers 13 installed on it, interacting with pads 14 mounted on the carriage 9, and hinged bolts 15 mounted on the carriage 9 9.

The cassette is collapsible and includes the spokes 16, connected with bolts 17 with a hub 18, in which a rolling pin 5 is mounted in the spindle 19. The hub 18 is fixed in the slot 4 with clamping nuts 20. On the spoke 16, a groove 21 is formed, along which in small limits (for centering the coil) the bolt 22 of the stop 23 is mixed.

The device works as follows.

With the horizontal unwinding of the waveguide, the carrier frame 1 is placed on the ground and the onopi i 3 is thrown away.

On one side of the cassette, the spokes 16 are removed and the waveguide bay is laid so that its internal diameter covers the stops 23, and then the removed needles 16 are set in place.

to 80 .m, which will reduce the number of joints and, consequently, improve the parametres of the waveguides, and, in addition, significantly reduce the unwinding tractive force and thereby exclude cases of deformation of the waveguide, i.e. quality.

The technical and economic effect of the implementation of the invention is ensured by an increase in the quality of the unwinding waveguide compared with the base object.
