Description

I .I.

Изобретение относитс кприбодостроению в частности к способу изготойлени полусерцечнйков дл магнитных головок, которые могут быть использованы в разнообразной аппаратуре магнитной записи.дThe invention relates to the field of construction in particular to a method for making half-centers for magnetic heads, which can be used in various magnetic recording equipment.

При изготовлении полусердечников дл магнитных головок из листового металла необходимо соблюдать р д предосторожностей дл того, чтобы не возникли, в процессе изготовлени пластин пакета, такиею влени как, например;,, наклеп. Устранению в некоторой степени этого процесса помогает электро-эррозионна обработка металлических листов и полученных полусердечников l .15In the manufacture of half-cores for sheet metal magnetic heads, a number of precautions must be taken in order to prevent the formation of package plates, such as, for example, ripping. To some extent, this process is eliminated by electro-erosion processing of metal sheets and the resulting half-cores l .15

Наиболее близким к изобретению по технической сущности и дocтигae 1oмy результату , вл етс способ изготовлени полусердечНИКОВ дл магнитных головок, пакет каждого из которых содержит установленнью в 20 его середине пластины полного профил , а по кра м - усеченные. Этот способ основан на вакуумном отжиге магнитом гких металлических листов, их химическом травлении дл получени п;1астин требуемой формы, 25The closest to the invention according to the technical essence and achieve the 1st result is the method of making half-hearts for magnetic heads, the package of each of which contains a full profile plate installed in its middle 20, and truncated along the edges. This method is based on the vacuum annealing of soft metal sheets with a magnet, their chemical etching to obtain n; 1 astine of the desired shape, 25

Сборки полученных пластин в пакет с послецукшим скреплением пакета и разрезкой технологических перемычек, а также на завершак цей обработке каждого пакета соответствующим инструментом на станке 21 . Однако при реализации этого способа точнос сборки пакетов и самих магнитных головок остаетс недостаточно вьюокой.Assembling the obtained plates into a package with post-folding of the package and cutting technological jumpers, as well as completing the processing of each package with a corresponding tool on the machine 21. However, when implementing this method, the accuracy of assembly of the packages and the magnetic heads themselves is not sufficiently twisted.

Целью изобретени вл етс повьтшение точности сборки пакетов и самих магнитных головок.The aim of the invention is to improve the assembly accuracy of the packages and the magnetic heads themselves.

Достижение поставленной цели осуществл етс за счет того что на станке первоначально производ т обработку пакетов по плоскоста разъема полусердечников до глубины , соответствующей ширине самой узкой пластины, после чего провод т обработку пакетов по плоскости контакта с установочным корпусом цо глубины, соответствующей требуемой ширине пакетов, при этом начало движени инструмента станка осуществл ютсо стороны носика каждого пакета,Achieving this goal is carried out due to the fact that the machine initially processes the packages along the half-core connector plane to a depth corresponding to the width of the narrowest plate, after which the packages are processed along the plane of contact with the installation case of the depth corresponding to the required width of the packages. This is the beginning of the movement of the machine tool from the side of the spout of each package

Claims

Ma 4ig. Figure 1 shows the preparation of full profile plates for 4 mg. 2 - plates of truncated pro4ml1Ts in figs; 3 - arrangement of metal sheets with obtained plates of figs. 4 - plate pack ntwiycefvdechnik; on ф г, 5 - processing of a package from a plane of the socket of half-hearts. on 4ig. 6 - processing of the package from the side of the plane of contact with the installation head housing. By the magnet, the soft metal sheet 1 is divided into sections 2, on which plates of full length 3 and 4 are formed; held by bridges 5 and 6. At the same time, insertion holes 7 are formed in the sheets. On the same sheets, plates 6 and 9 of the truncated profile are also formed. Cutting the technological peremyk 5 and 6, get the half core in the form of a package 9 having a thin section 1O for winding a coil (not shown) The package is fixed in the device 11, and its plates are compressed using the cheeks 12. Next, the packages are processed by the half-core connector plane passing through the nozzles 13 and the package section 14 using the tool 15, after which the package is turned over and processed by the same tool in the plane passing through section 16 and 17. At the same time, the tool is fed from the sides The nozzles are 13. The described method allows to increase the accuracy of package assembly and further on the magnetic head itself, as it is. the ability to conduct processing to a depth of 3 corresponding to the minimum width of any of the plates. Claims; A method of making half-cores for magnetic heads, each package contains complete profiles installed in its middle, and truncated along the edges, truncated, based on vacuum annealing of soft metal sheets with a magnet, their chemical etching to obtain plates of the required shape, assembling the obtained plates into a package with the subsequent fastening of the package and the cutting of technological jumpers, as well as the final processing of each package with a corresponding tool on the machine, distinguishing, and with the fact that, in order to increase Neither the accuracy of the package assembly and the magic heads themselves, on the machine, initially carry out the processing of packages along the flatness of the half-core connector to a depth corresponding to the width of the narrowest plate, after which the packages are processed along the plane of contact with the installation head housing, at the same time, the beginning of the movement of the machine tool is carried out from the nose of each package.
