Description

The known mechanized line for the manufacture of twisted tape magnetic cores, consisting of a magnetic core forming mechanism, a heat treatment furnace of a magnetic core, a magnetic core cutting mechanism, a drying chamber, a deburring mechanism, etc., are located along the process. But the known flow-mechanized lines do not cover all the operations of the technological process of manufacturing twisted magnetic tape magnets.

The proposed line mechanizes the whole process of manufacturing twisted tape magnetic circuits, which allows to improve the performance of the line and improve the quality of the magnetic circuits.

In order to improve line performance and improve the quality of the magnetic cores, the proposed flow-mechanized line, in addition to devices included in the well-known line, contains a press at the exit of the molding mechanism for repressing the mandrels of the magnetic cores; the mechanism of accumulation and cooling of the magnetic cores at the exit of the furnace; press for extrusion of mandrels from the product; transport device for returning the mandrels to the repressing operation ..: A cycle of operations carried out at plants and aggregates of a mechanized line allows to obtain ready-made magnetic circuits from electrical steel coils, tested by electromagnetic parameters.

Steel tape in rolls is fed to the device / cleaning for degreasing, where the tape is cleaned, washed, dried.

is wound on reels and transmitted to the insulation coating device 2. Insulated tape in reels goes to the mechanism 3 for forming blanks. With the forming mechanism wound blank

The magnetic core is transferred to the mechanism 4 for repressing mandrels for replacing the winding mandrel made of high quality structural steel with a calibration mandrel with a heat-resistant coating.

The billets of the magnetic cores, repressed on the calibration mandrels, are fed to the furnace 5 for heat treatment. From the oven tray, blanks of magnetic cores one by one fall into the loading device 6 of the mechanism

for accumulation and cooling and then on the cutting mechanism 7 of the magnetic cores. .-After .razkl-113-zagl1ovok magnetic device 9, which returns it to the mechanism of repressing mandrels. The preforms of the magnetic cores that are cut and cleared from the mandrels are dried in the drying chamber 10. The ends of the cut and dried core preforms are compiled in the deburring mechanism 11.

The finished magnetic conductors are checked for electromagnetic parameters on bench 12.

Subject invention

A flow-mechanized line for the manufacture of twisted tape magnetic cores, containing a device for ultrasonic cleaning and degreasing tape, a device for applying an insulating coating on the tape, a mechanism for forming magnetic cores,

oven for heat treatment. magnetic conductors. The cutting mechanism of the magnetic cores, the drying chamber, the deburring mechanism and the test bench arranged in series along the technological process, are characterized in that, in order to improve line productivity and improve the quality of the magnetic cores, a press is installed at the exit of the molding mechanism

to repress the mandrels of the magnetic cores, the accumulation and cooling mechanisms of the magnetic cores are placed at the exit of the furnace, and a press is used at the output of the magnetic cores cutting mechanism

mandrels from the product, associated with the repressor mechanism by a reverse conveying device that serves to transfer the mandrels to the re-pressing zone.
