    专利说明:

    The invention relates to electrical engineering, in particular, to a method of manufacturing a magnetic circuit consisting of E- and I-shaped plates, used mainly in a ballast device for gas discharge lamps. A magnetic circuit is known, consisting of E- and two L-shaped plates, in which a method of manufacturing is laid, which consists in that two sheets of E-shaped plates are pressed against one another and tightly adjacent to each other; -shaped plates are stamped with displacement relative to each other in such a way that the extreme rods of adjacent plates of one row of E-shaped plates are located between the extreme and middle lines of the P-oaseplate of the opposite section of the goldfin, and the L-shaped sections are stamped out of chastkov, formation between the outer rods and middle shoulder two rows of E-shaped plates l. However, a disadvantage of the known magnetic circuit design is that the plate package consists of three parts and therefore has insufficient strength, since the L-shaped middle parts are capable of tilting. A known method of manufacturing a magnetic core, consisting of E- and L-shaped plates, according to which, on a single sheet, stamped oppositely and tightly adjacent to each other with open sides, two rows of E-shaped plates, and from the sections formed between opposite rows of E-shaped plates, stamped t-shaped plates zj However, in the known method it is impossible to change the magnitude of the air gap of the magnetic circuit, since both side arms of a T-bar, closing 11} its reverse flow, must be pressed on the outer shoulders of the E-shaped core plate, which results in fixing a certain size of the air gap formed in the area of the middle plate, which cannot be changed. This means that the edges of the plates, which determine the air gap in the assembled state of the core, must have very small tolerances when stamping, otherwise it will not be possible to withstand the necessary width of the air gap. If, due to electrical conditions, it is necessary to change the air gap only slightly, then in this case the whole stamp should be changed, and with a slight wear of the tool it cannot be used anymore. The purpose of the invention is to increase the productivity of the method by increasing the operating speeds. This goal is achieved by the fact that according to the method of manufacturing a magnetic core, predominantly for a ballast device for gas discharge lamps consisting of H and t-shaped plates, two rows of E-shaped plates are stamped with opposite sides and close to each other with open sides on one sheet, and from the portions between the opposite rows of I-shaped plates, I-shaped plates are stamped, two rows of E-shaped plates are stamped offset from each other in such a way that the ends of adjacent to each other extreme shoulders of E-shaped plates of one row and adjacent to the end of the middle shoulder of the E-shaped plates of another row, and I-shaped plates extruded from areas formed | Between the extreme and middle shoulders of opposite rows of E-shaped plates, simultaneously Extra tamping grooves in the extreme shoulders -shaped plates. Due to the fact that with the proposed method of cutting, the outer edges of the outer shoulders are adjacent to each other, both grooves in them can be cut with a single stamp, and stable installation of this part of the tool is also achieved. In addition, due to the corresponding punching design, in addition to two grooves, a groove in the middle arm of the E-shaped plate of the median can additionally be stamped, which serves to receive the insert into the air gap. The stamping method according to the invention can be rationally designed in such a way that the I-shaped end plate is longer than the free space between the outer and middle arms of two rows of E-shaped core plates, as a result of which a package of I-shaped zamui; The plates can be inserted with a tension between the outer shoulders. This can also be achieved by punching the ends of I-shaped locking plates with bevels, however, with an additional advantage, which facilitates the insertion of an I-pack between external E-pack plates. In certain cases, it may be useful to increase or decrease the space to accommodate the coil. This task according to the invention is solved by increasing or decreasing the width of the I-shaped end plates. Thus, during punching, a greater or less height of the windows between the outer shoulders and the middle shoulder of the E-shaped core plate is obtained without the occurrence of waste ferromagnetic material. The stamping method according to the invention preferably serves to obtain a flat design of the throttles, and no waste of ferro-nitrous material arises. However, options are possible that require high throttle design without changing the width. This leads to the fact that the sum of the lengths of the middle and outer shoulders of the E-shaped core plate relative to the free space for the I-shaped closing plate is longer than the length of the I-shaped closing plate, due to which there is a slight waste of ferromagnetic material. A significant advantage of the proposed method is that, if necessary, an air gap between the middle shoulder of the E-shaped core plate and the 1-shaped locking plate, as a result of shortening the middle shoulder, extends the outer shoulder by the amount (amount) of the air gap, due to to which, without additional ferromagnetic material, an increased winding space is obtained. FIG. 1 shows a magnetic conductor consisting of B- and I-shaped plates; in fig. 2 - .the arrangement of the t-shaped plates of the core and the I-shaped plates of this throttle with the wasteless method of stamping; in fig. The 3-E-shaped plate of the core and the L-shaped closing chamfer with beveled ends, made by the proposed method; FIG. 4 shows the arrangement of E-shaped 1 64 core plates and I-shaped end plates in the stamping method of the invention with minor wastes. The choke (Fig. 1) has a ferromagnetic core consisting of E-shaped plates 1 of the core and I-shaped closing plates 2. The middle arms 3 of the E-shaped plates 1 of the core are covered with a coil 4, which after winding is put on the package of E-shaped plates 1 core. A deformable insert d is inserted between the 1-shaped closure plate 2 and the middle shoulder 3 of the E-shaped core plate 1, which is inserted into the groove 5, which is formed on the middle shoulder of the E-shaped plate. After the package of I-shaped locking plates 2 is inserted in an appropriate way between the outer arms 6 of the package of E-shaped core plates, the clamp bar 7, which, upwards and inwards with the curved longitudinal edges 8, covers the ends of the outer shoulders 6 and is pushed up with their longitudinal edges 8 in recesses 9 on the outer arms 6. FIG. 2 makes it possible to understand how the E-shaped plates 1 of the core and the T-shaped closing plates 2 for the throttles of FIG. 1 is obtained without waste from the sheet strip. In order to achieve waste-free stamping on one sheet, two rows of E-shaped plates are pressed against the opposite side and close to each other with open sides, and two rows of E-shaped plates are mounted with offset so that always the ends of 10 external arms 6 two C-shaped plates 1 of one row are adjacent to the end of the middle arm 3 of the t-shaped plate 1 of another row of core. With this displaced arrangement of oppositely directed E-shaped plates 1 of the core, the side is obtained by stamping sections between the outer arms 6 and the middle arms 3 of two rows of E-shaped plates, respectively, two I-shaped end plates 2, Notches 9 (FIG. 2) on the outer shoulders 6 and the groove 5 in the middle shoulder 3, which serves to receive the insert a into the air gap, as a result of the shifted S10 position of the E-shaped plates 1 of the core, are filled with one single die. To facilitate the insertion and press-in of the increased size of the t-shaped Package between the outer arms 6 of the E-shaped package, the I-shaped closing plates 2 have bevels 11, which, of course, are directed opposite to the bevels 12 on the B-shaped plates of the core (Fig. 3). FIG. A shows the location of the E; shaped plate 1 of the core and the t-shaped closing plate 2 with a small waste stamping method. Summd lengths of the middle shoulder 3 and externally
    S 2 3 1 2 e 6 of the shoulder 6 of the E-shaped plate 1 with respect to the free area, 11 lips of the I-shaped closing plate are longer than the length of the I-shaped closing plate, due to which waste A of the ferromagnetic material is generated. The advantage of the proposed method in comparison with the known one is that it provides the possibility of long-term operation of the stamping tool and higher operating speeds. In addition, with small changes in the air gap; no changes to the stamping tool are required.
