The invention relates to the technological equipment for manufacturing cores of magnetic cores and can be used in the field of electrical engineering.

The aim of the invention is to improve the dosing accuracy and to enable automation of the unloading process.

FIG. Figure 1 shows a general view of the section of the device at the time of cutting off the extra sheets of the foot from the metered P. package; in fig. 2 - device in the initial state.

The proposed device contains a press crimping mechanism,

including a cylindrical rod 1 with a central bore 2 in which plunger 3 is installed, spring 20 loaded with spring 4, Dispensed bag 5 is kneaded on mandrel 6 which is fixed to base 7, which can be moved relative to the mechanism for crimping the foot, for example, radial,

The device also contains a mechanism for cutting off the package from the foot, including a cross beam 8, the axial movement of which downwards is limited by adjustable stops 9, 10, which are arranged symmetrically with the central vertical axis of the device.

The mechanism for cutting off the package also contains two working elements 35, 11, 12 placed coaxially relative to each other on the traverse 8 and showing the possibility of axial and radial movement relative to

stock axis 1.

Work elements 11, 12 have grooves 13, in which axles 14 are installed,

mounted on the cross beam 8. In this case, the working elements additionally have the possibility of axial and radial displacement relative to the cross bar 8.

The movement drive of the working elements 11, 12 contains a hydraulic cylinder 15, the piston rod of which is rigidly connected to the wedge nozzle 16, inside which is installed a plunger 3, two crackers 17, 18, which are in contact with the wedge surface of the nozzle 16 and working elements 11, 12. Work elements equipped with spring-and-noavrata 19, 20.

The spring 4 of the movement of the plunger is placed in the chamber 21 between the wedge nozzle 16 and the plunger 3 along the central axis of the nozzle. The spring of the traverse 22 is placed in the chamber 23 also located along the i, t-: HT axis of the nozzle 16, below the chambers - 21, The cylindrical rod 1, designed for pressing the steppes of the sheets, has the possibility of axial movement from the "deep plunger 3 and nozzle 16 Axial movement of the crosspiece 8 relative to the nozzle i & limited by the height of the window 24, in which the pin 25 is placed. The radial movement of the wiper elements P, 12 is determined by the wedge surface of the nozzle 16, along which the crackers 17, 18 can be used, reciprocating with the working elements. Moving the working elements along the center of the axis of the device is determined by moving the crosspiece 8. In addition, it is possible to axially move the working elements il, 12, to the height of the gap 13 ii, the possibility of rotation relative to. SR-th 14, fixed on the traverse 8.

Movement along the central oc of the device of the spanner 8 and the cylindrical rod I, which is rigidly connected with the plate 26, is carried out by a crimping drive, made, for example, in the form of a hydraulic cylinder (not shown). In addition, the movement of the crosspiece 8 is additionally carried out when the nozzle 16 is moved, which is connected to the piston rod of the hydraulic cylinder 15.

The height of the package 5 to be dosed is determined by the distance between the compartments of the working elements 11, 12 and the base of the mandrel 6 and is adjusted by the stops 9, 10.

The plunger 3 is provided with a stop 27, which ensures its retention in the lowest position relative to the nozzle 1 6.

The device works as follows.

On the mandrel 6, for dosing of packages, a sheet of sheets is installed, the height of which is somewhat higher than the height 1 of the HQK of the dosing package 5. At the same time, the rod 1 is in the upper (initial) position, the plunger 3 is maximally extended and held

stop 27. The nozzle 16 is in its highest position. Traverse 8 is also in the upper position, which is determined by the upper position of the pin 25 in the window 24. Crackers 17, 18 are maximally shifted to the center axis of the device, and the working elements 11, 12 are open

at. spring support 19, 20. I

Rod 1, moving down with

drive crimp, compresses zadinm effort foot sheets. When a command is received to turn on the hydraulic cylinder 15, its rod moves the nozzle until it contacts the mandrel 6 and the crosshead 8 until it comes into contact with the stops 9, 10. Then, during the downward movement of the nozzle 16 relative to the plunger 3, the nozzle 16 is compressed relative to the crossbeam 8, the spring 22 is compressed, and the conical surface of the nozzle 16 pushes the crackers 17.18, providing movement of the working elements 11, 12 to the stack of sheets. When this happens, cutting off the extra sheets of the foot from the package 5.

After the command to reverse the crimping drive (not shown) is received, plate 26 and stem 1 are associated with it.

move up. When this occurs, the upward movement of the traverse 8 with the working elements 11, 12, which hold the excess sheets of the foot, remove them from the mandrel 6 and push them to the end of the rod 1.

In the process of removing extra sheets from the mandrel, additional working elements 11, 12 are moved relative to the axis 14 and along the groove 13 in the direction of the mandrel 6, which compensates for the pressing of extra sheets and eliminates the loss of the trimmed sheets by the mechanism for cutting off the package from the foot. The sheets of the overdose package interlocking with the separated part of the foot are discarded when passing through the plunger 3 and remain on the mandrel 6. After removing the overdressed package 5 with the mandrel 6 from the working position, a mechanism is cut off to cut off the package. This is accomplished by reversing the hydraulic cylinder 15, during which the nozzle 16 moves upwards.

The crackers 17, 18 are released and moved by springs 19, 20 to the axis of the mechanism, the working elements 11, 12 are rotated around the axes 14, freeing excess sheets and the mechanism for removing the bag is unloaded.
