At the same time, the main belt conveyor and transverse conveyors, respectively, in the area of the blasting unit, the lower dies cleaning unit and the unit for filling with energy transfer material are equipped with lowered stops. In addition, the device is equipped with a roller conveyor located in the area of the product supply unit, a telemetr having a centering unit, a transfer unit with a lifting mechanism and a grapple, as well as those placed in the assembly area for removing items - a transfer unit having a grapple with a safety button mechanism, are lifting unit and a roller conveyor cleaning unit. The device is also provided with 1-arranged parallel to the main belt to the return conveyor of the preparatory belt conveyor with the connecting parts of the belt conveyors having. at their ends are turning parts and mounted on mechanized, reversing the transport direction of the parts of the tapered conveyors. In the lower part of the blasting unit, channels for the removal of energy transfer substances are made and fast wearing plates are fixed, and the node For filling with a substance for energy transfer is located in the area of the tactical fill of the explosive substance and is connected to the discharge and dosing units. FIG. 1 schematically shows a device for the explosive shaping of hollow bodies, a general view of / in FIG. 2 - supply of products returnable conveyor belt; in fig. 3 withdrawal of products by the main belt conveyor; in fig. 4 -, knot for explosive shaping, cut. The described device for blasting hollow bodies contains a main belt conveyor with a tactical device 3, a transverse belt conveyor 5 with a chain drive 6, a returnable longitudinal belt conveyor 10 with a chain transmission 11 and a transverse belt conveyor 13 with a chain transmission 14, which are located one relative to other at right angles. The device also comprises mechanized, changing the transport direction parts of the belt conveyors 4, 9, 12, 16, by means of which the said longitudinal and transverse belt conveyors are connected to one another at corner points. The described device also contains a unit for cleaning the lower dies 7, located on the transverse belt conveyor 5, and a unit 15 for filling with energy transfer material, placed on the transverse belt ITQ4HOM conveyor 13.

In the lower part I of the blasting unit 1 there are drainage channels for the energy transfer substance 1b and wear plates 1c. The described blasting device operates as follows. The deformable products above the feed roller conveyor 18 and the compartment by the tele 19 are placed in the lower dies by the grapple 20 at the common corner point of the transverse belt conveyor 5 and the return conveyor 10. By means of a chain transmission 11 on the return belt conveyor 10, the product is moved until the part of the conveyor belt 12 that changes the transport direction and transferring to the transfer film belt, conveyor 13. Bottom stamps with deformable pieces of chain transfer 14 moving to the node for filling with energy transfer substance 15 , position the lower stop 8 and the product is filled with a matter of energy transfer. The transfer-changing part of the conveyor.16 transmits the lower rods 7 to the main belt conveyor 2 and, through the stroke aggregate of the explosive substance 35, moves to the unit for explosive change 1, where the products are molded. In the tactical spacer of the explosive substance 35, the loaded hollow spaces are filled with energy transfer substance via the metering 34 and the discharge 33 mechanism. After the product shaping has been completed, the lower dies are moved in steps to change the transport direction of the part of the conveyor belt 4, where the deformed products are removed with the grapple 25 from the lower die, are cleaned and retracted by the roller conveyor 23. By changing the transport direction of the conveyor belt 4, the lower dies move on a transverse belt conveyor 5. Using a chain drive 6, the lower dies are moved to the cleaning unit 7 of the lower dies, positioned by the lowered stop 8 and cleaned. Then, the lower dies are moved to the reversing transport direction of the part of the belt conveyor 9, where they are again loaded with deformable products. When using the described device, due to the closed-loop transport system, it is possible to divide into individual cycles, as a result of which high productivity is achieved, and time is simply reduced. Separate placement of individual assemblies improves maintenance conditions, and the presence of wear plates: provides a long-term use of the assembly for explosive change.
