Abstract

The invention relates to the processing of metals by pressure. The purpose of the invention is to increase productivity by reducing warp-on changeover. The device consists of a rotor, a receiving table with a roller conveyor, a bending beam fixed on two-arm driving levers. The levers are connected by a bar, on which the clamping yoke with grippers in the form of brackets with rollers is placed with the possibility of rotation. The workpiece is installed on the receiving table between the presser beam and the rollers. When bending, the clamp bar turns toward the table and presses the workpiece against it. The invention makes it possible to exclude a retooling operation for the rebar grids with different rod diameters. 4 il.

Description

The invention relates to the processing of metals by pressure, in particular, to devices for bending reinforcing meshes.

The purpose of the invention is to increase productivity by reducing the time to changeover.

FIG. 1 - the device, a general view is presented; FIG. 2 is a view A of FIG. 1; on fig.Z - view B in figure 1; Fig, 4 - section bb In Fig.Z.

The device consists of a frame 1 with a receiving table 2 mounted on it and a roller table 3, a bending beam 4 rigidly mounted on 5 double-arm levers 6 driven by power cylinders, a clamping yoke 7 mounted on a rod 8 connecting the levers 6, can be turned into side flexible. Along the clamping yoke, placed grips, each of which is made in the form of a bracket 9 with a roller 10. Each ozahvat equipped with a locking screw. Buffers 11 are mounted on frame 1 to maintain crosshead 7 in a non-operating horizontal position.

The device works as follows

The grid to be flexible is laid on the live rolls 3 and, by displacing it along the table 2, the longitudinal bars of the grid are set to the required bending size. Then, displacing the grid across the table, guide the rods into the gap between the clips 9 of the clamping yoke 7 and the rollers 10. Then turn the power cylinders 5 on the extension of the rods. The levers 6, turning on the rod 8. act through the bending beam 4 on the bendable grid. The clamping yoke 7 is gripped by the longitudinal rods of the grid and, overcoming the compression force of the buffers 11, rotates towards the receiving table 2, pressing the grid rods to it, ensuring the self-adjusting pressing force. At the end of the reinforcement bend, the power cylinders are turned on in reverse.

When using the proposed device, its operation is simplified by eliminating the changeover operation for bending rebar with different rod diameters.
