The invention relates to devices for electrically heating reinforcing bars and can be used in production lines for the manufacture of pre-stressed reinforced concrete products.

The purpose of the invention is to expand the technological capabilities of the installation.

Figure 1 isob1-1, installation, front view; figure 2 is the same, top view; fig.Z - node I in figure 2; on figa - section LA in fig.Z.

The installation contains a frame 1, a device for electrically heating the rods 2, hinged multiple parallels Пl 3, one of the ends of which consists of two links 4 and 5. Link 4 is sharply attached to the rod 6, along which the slider moves 7 Link 5 is attached to the slider 7, driven by a rod 8 of a S1SHELLO cylinder 9 by means of pulling 10. The other end of each parallelogram 3 is packed with a holder 11, driven by 1 by a pneumatic cylinder 12. For making the parallelogram system stiff, they are connected by a bar 13. For supplying heated Rebar rod 14 on parallelograms 3, which together represent pavlonnyh guides, used a pusher 15, equipped with a pneumatic cylinder 16. P up to accommodate a large-sized form 17 with stops 18 for reinforcing rods 14. On the base 1 mounted stoppers 19, connected by rods 20 pnepmotsilpidrov 21.

The installation works as follows.

The required number of rods is laid with a lifting device on the bed frame I. The reinforcement bar 14 is clamped to the jaws with the jaws of the device- 2 and is electrically conductive. After the rod is heated to a predetermined temperature, the sponges of the device 2 are expanded, the pneumatic cylinders 16 are turned on, which by the pushers 15 feed the rod 14 on the plane of the inclined guides of the multiple parallelogram 3, which rolls along the holders 11. After that, the power cylinder 9 turns on the rod 8 acts on the rods 10 and moves the sliders 7 along the rods 6, as a result of which the hinged multiple parallelograms 3 lengthen and the heated rod 14 is fed to the stops 18 of the form 17. This includes pneumatic cylinders 21 and stock Kami 20 push out the stoppers 19 against which the slides 7 abut, as a result of which the elongation of the parallelogram 3 stops. Then, pneumatic cylinders 21 are turned on, which rotate the holders 12, the rod 14 is placed in the lugs 18 of the mold 17, and the parallelograms 3 are returned to their original position.

Form la invention

An installation for electrically heating reinforcing rods and placing them in shape stops, comprising a frame, an electric heater of rods, a mechanism for dispensing a heated rod, a mechanism for lateral movement of the heated rod, and a mechanism for placing rods in the stops, which by automating the laying of heated rods into the stops of large-sized form, the mechanism for stacking the rod is made in the form of a system of articulated multiple parallelograms and power cylinders, each rod Of these, the guide element and the slider are hingedly connected to the frame, and the installation is equipped with a slider stop mechanism, which is designed as a stopper with a pneumatic cylinder.
