Description

ate

The invention relates to the processing of meta-patterns by pressure and can be used when bending reinforcing meshes.

The closest to the invention to the technical essence and the achieved effect is a device for bending afe aTypHbix nets, which contains two racks supercharged on the base, an adjustable bending matrix consisting of two movable legs, a vertically movable traverse with bending hooks and a traverse descent limiter.

The disadvantages of the known device are the impossibility of bending amaturgen sets without welding connections, the difficulty of retooling the machine at different angles (radius) of the reinforcement bend, and the dashboard lacks the durability of the working parts of the die.

The aim of the invention is to expand the technological capabilities by providing flexible reinforcing meshes outside the welded joints, as well as increasing the durability of the device and simplifying its readjustment.

The goal is achieved by the fact that the device for bending reinforcement: grids containing two pillars fixed on the base, a knotted bending matrix consisting of two movable beams, a vertically movable traverse with bending hooks and a traverse descent limiter, is equipped with a pivotal one fixed to one of the struts lever, bearing a bending mandrel, located with the possibility of free movement during the movement (t in the slot that was inserted in it).

In addition, the caps, which form a bending matrix, are installed with the possibility of horizontal displacement relative to each other and equipped with detachable ones installed in the rh-shaped slots made in them (with durable inserts made of wear-resistant material, the possibility of horizontal displacements, pereshshkutgarno longitudinal rods of the grids.

Fig; 1 schematically shows the proposed device, a general view; in FIG. 2, view A in FIG. one.

The proposed device for day bending of reinforcing grids contains fixed chisels of the base 1 of the rack, on which the adjustable bending matrix 3 is fixed and the vertically movable yoke 4 with the bending hooks 5 is attached to the body.

The drive and b are fixed on a common base with the side racks. In order to stepwise change the angle of the bend of the bending reinforcement

The grid of the proposed device contains interchangeable step limiters 7 for lowering the said traverse, which are installed with the possibility of horizontal movement perpendicularly

The grid rods of the grid are in the corresponding grooves of the side posts along the guides 8. The height of steps 1i. each pair of step stops is selected individually depending on the nos.

5 product lists.

To make it possible to smoothly change the angle of the bend d and the bend radius g of the bent rods, the above-mentioned flexible matrix is made of two beams attached end to end on the side posts and installed with the possibility of fixed horizontal movement relative to each other. The matrix beams are interconnected by a screw 9, with the help of which these beams are moved.

The basis of the possibility of bending nets outside the welded (guttings, as well as bending nets at the welded intersections when

0, where d and 61 are the diameters of the pro: longitudinal and transverse rods of the grid. The proposed device is equipped with a detachable mandrel rod Yu, which is moved by using two drives 11.

to the grooves of the guiding rotary {lever 12, it is possible to feed FROM the initial position to the bending zone. With a chain to increase the service life of the machine in the open grooves of the matrix beams are quick-change

Q support inserts 13.

The ratio d 2d determined empirically. If this ratio is violated, local distortions of the longitudinal rod occur.

The device works as follows.

The actuator 6 is connected, connected to the crossmember 4. The hooks 5 attached to the crosshead 4 are raised to the upper position. The mandrel 10 is also displayed in the upper position. An armature mesh is placed on the matrix 3, and the drive 6 is turned on again. The traverse 4 is lowered to step h) from the reducer 7, and the hooks 5, by gripping the bars of the grid, bend the product to the required angle. Then the hooks 5 are raised, the net is removed from the bends.

In the case of welded mesh. intersections with d: SK 2 wake up

LED 11, the mandrel 10 and the hooks 5 are lowered onto the grid, grasping the mandrel 1O. The curved grid bars of the grid are bent to a predetermined flow greater than the design flow of a spring and spring. Then the yoke 4 with the hooks 5 is lifted, releasing the mandrel 10. The drive 11 is turned on, which moves the steering rotary lever 12 together with the mandrel 1O from the bending zone to the upper smoke.

All working bodies return to their original position, and the bent mesh is removed, and they are rearranged to the position for the next bend and the bending cycle is pressurized speed.

For bending of the grids at the welded intersections with c37 / 2, the mandrel 10 is not required. Hooks 5. Will act directly on the ground-wire rod of the grid along which the bend line passes.

Banks are set to the average of possible pushes, and getting the required bend is achieved & Neiii of the corresponding stepped ogreaders 7 and their installation in the appropriate position by the value of the height of the step. If necessary, the value of the angle of bending of the C is corrected by changing the gap between the banks. The dependence of the bend angle on the gap between the banks is inverse, i.e. an increase in the gap between the beams leads to a decrease in the angle of the bend and, vice versa, a decrease in the gap increases to an increase in the angle of the bend. The change in the gap between the beams is straight. If the gap is changed to reach the required radius, then the step stop 7 and its installation location

the corresponding 4th value of the gap between the matrix beams is selected. If the profile of the bent mesh contains two or more values of the bend angle, then in the intervals between the bending cycles, the step restraints 7 are moved to the specified new position. In this case, they use step limiters with a corresponding set of step heights / hj.

Support inserts 13 installed in the grooves of the matrix 3, when abrading the surface in contact with the reinforcing mesh, remove them from the pins and, turning 90 °, re-install on these pins. A removable support insert is alternately in the flexible zone; | From various sides, i.e., the service life of the machine is 4 times longer.
