Abstract

The invention relates to the processing of metals by pressure, in particular to the mechanization and automation of press and blank production, and m. used in manipulated tori. The goal is enhanced functionality and performance. The device comprises a frame 1 with a suspension 2 rigidly fixed on it with guide rollers 3. The frame 1 is mounted on racks 4 with wheels 5 located between the stops 7, the Middle stop. 7 is made in the form of an electric magnet core 8 consisting of a core 9 and a winding 10. Anchor 8 is equipped with return springs 1I. The device comprises a table with a foot of 12 blanks 13 and an additional table 19 with a foot of 21 blanks 13. Tables 14 and 19 are made of electrically conductive material. The device allows, without any obstacle, to load a new stack of blanks for supplying it to the treatment zone by rolling back the frame 1, 1 sludge. § SL

The arrow 17 indicates the direction the sheet 13 moves to the treatment area, and the arrow 18 indicates the direction of rollback of the frame 1 with the inductor 2, The device is equipped with an additional table 19 made of electrically conductive material and mounted on racks 20, and the height of the upper plane of the table 19 is equal to the total height of the table of the hydraulic lift 15 and the foot 12 steel sheets 13, and the length of the table 19 is equal to the length of the rollback frame 1. On the additional table 19 is located the next foot 21 of the ferromagnetic sheets 13.

The device works as follows.

The treatment zone of the last sheet of table 14 is separated from the inductor 2, connected to the source of three-phase voltage, with a small air gap of 15-25 mm. The electrical conduction of the table 14 is crossed by the traveling magnetic field and interacting with this magnetic field is induced in it.

As a result of this interaction, a force is created, which straits to move table 14 in the direction of arrow 17, but table 14 is rigidly secured and remains fixed. At the same time, the inductor 2 is acted upon in the direction of the arrow 18, but the wheels 5 are located between the restraints 7 and do not allow the inductor 2 with the frame 1 to roll back.

The treatment zone of the last sheet, table 14, is separated from the inductor 2, connected to a three-phase voltage source, with a small air gap of 15-25 mm. The electrically conducting table 14 intersects the traveling magnetic field, and currents interacting with this magnetic field are induced in it.

As a result of this interaction, a force is created which tends to move the table 14 in the direction of the arrow 17, but the table 14 is rigidly fixed and remains with the fixed one. At the same time, the inductor 2 is acted upon in the direction of arrow 18, but the wheels 5 are located between the stops 7 and do not allow the inductor 2 with the frame 1 to roll back. When serving

the three-phase voltage source on the coil 10 is electrically driven by a traveling magnetic field crossing the top steel sheet 13 of the foot 12 and the electromotive forces driving it causing the magnetized measles 8 to break the resistance of the springs 11, is pulled into the core 9. This releases the wheel 5, held by the middle of the magnetite 8, overcoming the resistance of the springs 11, is drawn into the core 9. At the same time, the wheel 5, held by the middle limit, is released. The new stop 21 of ferromaps sheets is removed from the additional table 19. Iod by the action of the force acting on the inductor 2 (in the direction of arrow 8), the frame 1 is mounted on the uprights 4 and the wheels 5 move (roll away in the direction of arrow 18). At the same time in the zone

the inductor enters a stationary electric IQ holding lifting table for placing the conducting table 19, which is crossed by a running magnetic field. It induces currents that interact with a traveling magnetic field. As a result of this interaction, a force is created under the action of which the inductor 2 with section 1 continues to roll back in the right direction of the arrow 18 until the wheel 5 rests on the right support 7. The winding 10 of the electromagnet turns off and the device is between two limiters 1-1i: him and the right (under the action of the springs the bark 8 moves upwards). At this time, a stack of 21 sheets 13 is loaded, for example, with a crane on the table 14. The direction of the traveling floor of the inductor 2 is reversed (two different phrases are swapped) ) include electromagnet coil 10 and inductive p 2 with frame 1 rolls back to its original place. Again, the direction of the traveling magnetic field is changed.
