Abstract

The invention relates to the technology of making twisted tape magnetic pipelines, and used in electronic, electrical, electrotechnical. instrument-making and other industries. The aim of the invention is to improve the quality of the cutting tape magnetic cores by reducing eddy current losses. Way; The fact is that after winding the first turn of the magnetic circuit, the second turn is welded, which is boiled and welded to the first turn. Similarly weld all subsequent turns. During one revolution of the magnetic circuit, at least six weldings are performed. After reaching, a magnetic circuit of a given size is annealed, then cut and dried. 2 Il. 00 ate about 05 00 4

The invention relates to a torsion angle, a second angle, and the welding point receives a manufacturing twisted ribbon tape extended along the tape. Such plumbing and can be used for the welding zone does not impair the electrons in the radio engineering, electro-magnetic parameters of the magnetic circuit,

In other words, the direction of the zone coincides with the emission bands. The direction of the magnetic flux.

The aim of the invention is to improve since the mandrel has the rectangular quality of the split tape magnet form, and the location of the weld point by reducing the losses on the key is arbitrary, the distance from the eddy currents of the optical system of the laser to the magnetic board. 1, the implementation schema of the wire is constantly changing. Besides

this method; in fig. 2 -thas, according to the size of the winding, the size of the magnetic core is magnified;

navivka axis. influences this distance. To reduce magnetic fluxes, they make the vibrations of this distance, including machine 1 for the size of the welding point of the installation, the optical system 2 of the installation used for the laser-laser radiation measuring technique proposed by NONKI, 11 there is a long focus optical calibration setup 3, a machine 4 for chesting system, cutting, a dryer 5 and a stand 6 control. 20 To increase productivity

Before winding the magnetic circuit of this method, a fastening of the tape 7 can be applied to the frame to equip a more powerful laser device 8 of a rectangular shape and start, for example, a gas laser. In this winding. The rotational speed of the acid welding of the turns is limited by the repetition frequency of im-, a continuous line along the pulses wound to 1 Hz, and it is equal to the tape. em 10 rpm. After reaching the magnetic core

After winding the first turn, that is, the e size specified is produced

after the mandrel with the fixed-annealing in the calibration setup at

 Noah on it. the tape makes one obo- - 850 ° C for 20 minutes, the mouth makes welding of the second one. The removal of the twisted coil occurs. Pinch roller 9. The ripples arising in electrical engineering carry out a dense packing of the ribbon on the cicke steel at the mandrel from bends. The second coil is boiled at the corners of the mandrel: with a full impulse and welding, 35 O1 at the same time blink the metal and enter the first coil. Similar places welding coils.

this is how all subsequent turns are welded. Then the magnetic core is cut

To ensure the durability of the floor- cutting machine with an abrasive wheel

Nok magnetic core after cutting 40 with a thickness of 2 mm. During cutting

the welding points must be positioned in such a way that the magnetic core is clamped from two to one, so that any two semi-turns are connected in a direction parallel to a plate less than at two points. The outcome of the abrasive wheel, split

This requirement, and taking into account the fact that by means of 1, located on both one hundred and two points can fall into the zone of a resolution of 45 Po «bi from the circle. This provides for, for. one turn of the magnetic conductor reliably securing the rods to produce at least six welds. This is the Cut.

is achieved by the fact that welding is performed by cutting

The number of single pulses from the often-magnetic circuits and their control with an electron is at least 6 times higher than 50 magnetic parameters. At the same time, due to the speed of rotation of the magnetized magnetization, the no-load current and the loss of the nitromide and the component in this magnetization reversal,

example 1 Hz, welding can be produced simultaneously with welding

It is also possible to significantly reduce not the width of the tape, the size of the melted zone, and, consequently, eddy currents, which during the welding time doesn’t matter the quality and efficiency of the magnets. rotates on some of the nitros.
