SU757233A1 - Apparatus for bending reinforcing frames - Google Patents

Description

The invention relates to the return of metals by pressure, in particular to devices for flexible reinforcing cages.

A device for the manufacture of frames, columns, containing mounted on the bed table with a movable middle ₅ and bending rolls [1].

However, with the help of such a device it is impossible to obtain products of various shapes.

The closest in technical essence to the proposed is a device for bending reinforcing cages, containing a driving bending tool fixed on a frame and a table mounted on it on supports [2].

On this device, it is possible to bend the frames to different angles by adjusting the bending tool, but this adjustment is carried out in a small range. In addition, the frame to the bending tool is pressed manually.

The aim of the invention is to expand the range of bending angles. 20

For this, the proposed device is equipped with a stop mounted on the edge of the table on the side of the bending tool, and also 2

the same mechanism of inclination of the table, made in the form fixed on the frame with the possibility of rotation of the shaft with eccentrics associated with placed under the abutment table supports, and supports the opposite edge of the table mounted on the frame hinged.

FIG. 1 shows a device with a raised table for bending an acute angle of the frame, a general view; in fig. 2 - the same, with the table lowered to bend a right angle; in fig. 3 - shaft lock; in fig. 4 is a view A of FIG. 3

The device consists of a frame 1, on which hook hooks 2, a drive bending tool 3, a rotary shaft 4 with eccentrics 5 and hinges 6 connected to the supports 7 of the table 8 are mounted. table 8 fixed stop 12. At the end of the frame 1 is fixed dividing scale 13, and at the end of the rotary shaft 4 is pivotally fixed the handle 14 with the latch 15, spring-loaded in the direction of the axis of the shaft 4 by spring 16.

The device works as follows.

757233

The reinforcement cage 17 is hung on

hook hooks 2 for the longitudinal rod 18. Due to the inclined position of the table, the frame is pressed against the hook hooks 2 and the stop 12. When the drive of the bending tool 3 is turned on, the frame bends around the rod 18 at a predetermined angle. The presence of the stop 12 ensures the constancy of elastic deformations at any angle are flexible.

To change the angle of the flexible clamp 15 is removed from engagement with the dividing scale 13 and, turning the handle 14 relative to the axis of the shaft 4, set the latter in a predetermined position. In this case, the eccentrics 5 through the housings 11 and the connecting rods 10 rotate the table 8 relative to the hinges 6, as a result, the emphasis 12 occupies a new position, which determines the bending angle. Next, the frame is hung after another longitudinal rod, the process repeats.

The optimum angle of inclination of the table is 15-60 °, since under these conditions the frame fits tightly against the stop 12 and reliably comes under the grippers 2.

Claims (1)
