Description

The invention relates to electrical engineering, in particular to manufacturing equipment for the production of magnetic circuits of electrical machines.

The purpose of the invention is to automate manufacturing and increase the productivity of a production line.

FIG. Figure 1 shows an automatic production line for the manufacture of magnetically guided electric machines; in fig. 2 -

a sheet, and a dented area of the rotor 21 with a part of the frame 22 (Fig. 2) and a stator sheet 23 for a low or medium power electric motor. The next system of presses 12 and 13 cuts down the tooth-like zone of the rotor 24 (FIG. 2) with an incomplete load and the stator plate for a medium or high-power motor, observing that every next sheet of the rotor and stator is older. As for the deschema stamping on the proposed line; rotor hoists having the form of a dentate zone c in FIG. 3 - a detail of the magnetic circuit with a stapled incomplete {fig. 4) then these details

waters with additional romm. In the induction furnaces, they prepare the ferrotechnical line includes unwinder 1, a romagnetic melt, which is introduced into the horse of which roll 2 is placed with an electrolytic tape with packages of rotors of the casting machine,

Technical steel 3, the correct device. 20 Strictly dosed melt fills in at 4, after the compensation loop 5 of the rotor flap, the central hole, forming a bimetallic bond of the laminated bag with the massive part. Thus, the massive part became an additional rome 26 of the rotor 27 (Fig. 7). After cooling, the bags are removed from the casting machine for further process steps.

The vehicle 8 (FIG. 6) is a kinematic system, the status 3 is provided with the feeding device 6 on the first press 7, the vehicle 8 (FIG. 6) with the second compensation loop

5 presses 9-13. The electrical circuit of an automatical line with the control panel is not shown on the drawings.

Unwinder 1 is a rotating drum device on which roll 2 of electrical steel is placed.

given width. From roll 2, the tape 3, ejected from the first reel 28, is installed in the correct device 4, in which the line in the previous press, the necessary tension is carried out on the press 7 (fig. 1). On the drum

you. Through the correct device 4 tape, placed clamps 29, which

forming a compensation loop 5, it is located in two rows. Distance between

to the feeding device 6, which is equal in size to the distance between the technology on the press 7. On the first press openings 14 and 20. Radially

In the on-off stamp, the tech-located catches 29 are cut down; the relative apertures 14 (Fig. 2), they are the same as the distance between the process holes and the shaft holes by micro-holes 14 and 20, made

The gateway also cuts the holes in the bottom of one of the edges of the tape 3. The second baraval 15 micromotor and the slots of its rotorabane 30 of the vehicle 8 have

16. In the second position, the external design is cut in the same way as the diameter of the rotor 17 and it removes the raban 28, and it is installed on the next one from the stamping zone or on the dip, the press, for example, the press 9, before in the side window of the press 7. The inter-device 6 (on all presses with press 7 and 9, the material has the second lumping devices the same). Drums 28

pensation loop 5, located inter-. and 30 are connected by a flexible kinematic front of the reels of the vehicle 8. The feeding device on the press 9 supplies the press 2 to the press and the second press 9 for two or three blows cuts first the slots of the stator 18 (Fig. 2) and then the entire stator 19 (FIG. 3). The coil is fixed by a lorger by the stampers through the technological holes, first 14 and then 20 (Fig. 2). Thus, the system of presses of the type “Tandem performed part of the technological process - a sheet of the rotor and stator were cut out

31, for example a chain. Pinch rollers 32 are used to rotate the belt 3 in a given direction.

The vehicle operates as follows.

In the press 7 during the punching of the tape 3, the tape is given a rhythmic movement, it is pushed out of the press with a step equal to the transition of the punching operation. At the exit of the press through the window, the tape falls on the drum 28 of the vehicle 8, slides

micromotor and technology are formed 55 along its surface until the fic holes. On presses 10 and 11, the catcher 29 will not enter the technological holes 14 and 20, made on the tape 3. Logged in with the tape.

similar operations are completed, only the axis of symmetry of the tape cuts not the rotor sheet, but the dentate zone of the rotor 21 with a part of the frame 22 (Fig. 2) and the stator sheet 23 for a small or medium power electric motor. The following system of presses 12 and 13 cuts down the dentate zone of the rotor 24 (Fig. 2) with an incomplete load and the stator plate for a medium or high-power electric motor, respecting each next sheet of the rotor and stator to be older size. As for the parts of the rotor, having the form of a dentate zone with an incomplete seam {Fig. 4) then these details

kih operations.

Vehicle 8 (FIG. 6) is a kinematic system, with gear 31, for example, a chain. Pinch rollers 32 are used to rotate the belt 3 in a given direction.

The vehicle operates as follows.

In the press 7 during the punching of the tape 3, the tape is given a rhythmic movement, it is pushed out of the press with a step equal to the transition of the punching operation. At the exit of the press through the window, the tape falls on the drum 28 of the vehicle 8, slides

the drum 28 begins to rotate, unfolds the tape, and the pinch rollers 32 facilitate uniform adherence of the belt to the drum. Next, the tape is pushed in the direction indicated by the arrows into the channel (not shown), a compensation loop 5 is executed, after which the tape 3 hits the B drum 30. The hook picked up by the catches and pressed by the roller 32 the tape is fed into the setting device 6 of the press 9. Drums 28 and 30 are connected by a chain 31, which causes the drum 30 to rotate. Such a connection maintains the same rhythm of rotation of the drums, provides equal force to the tape and helps reduce the compensation loop to the minimum possible limits .

Sheets of the rotor and stator of micromotors, as well as sheets of stators of higher dimensions are assembled in accumulators made in the form of hollow mandrels. From the accumulators, the sheets are guided to devices in which packages of magnetic cores of a given length are assembled. Packages of stators of all dimensions and rotors of micromotors are sent for further assembly into packages.

All presses can work independently, each from their own control panel, but more economically when they are connected by a single electrical circuit and controlled from one control panel.
