    The invention relates to the technology of manufacturing electrical apparatuses and can be used in electrical engineering.
    The purpose of the invention is to increase the transverse cross section of the magnetic circuit in a waste-free process.
    FIG. shows a core assembled from i-shaped and T-shaped plates, side view; in fig. 2 - the location of the i-shaped plates of the core and the T-shaped plates of the reverse closure with the waste-free method of stamping; in fig. 3 - the same, option.
    The core of the throttle or transformer (Fig. 1) is assembled from I-shaped 1 and T-shaped 2 plates of the reverse circuit. Each U-shaped plate 1 has two parallel, bounded by the right planes of the side rods 3 and the middle rod 4 connecting them, passing at a right angle to them. Between the two lateral rods 3, T-shaped re-closing plates 2 are pressed in with a transverse rod 5, from which the longitudinal rod 6 departs in the middle, at a right angle. From the side; the end of the longitudinal rod 6 can have an air gap 7 in which deformable liner.
    i-shaped 1 and T-shaped 2 plates are cut from a tape of width 8 using a sequential punch (Fig. 2). This ensures that two rows 9 and 10 of U-shaped plates 1 oppose each other with their open sides and each side pair rods adjoining each other in pairs adjacent to each other 3. The I-shaped plates I adjacent to each other I of both rows 9 and 10 are displaced along the tape relative to each other so that 2 pairs of side rods 3 of the same row are always adjacent from the inside side to a pair of side bars 3 u -shaped plates I of another p yes. All U-shaped plates 1 and T-shaped plates 2 have the same sizes and dimensions.
    From the free areas located between the ends of the II pair of side rods 3, and the middle rods 5 of the 4 I-shaped plates 1 located at a distance from these ends, the T-shaped plates 2 of the reverse circuit are cut out. At the same time T-shaped plates 2 with their transverse
    The rods 5 are adjacent to the middle rods of the 4 and-shaped core plates, and the length of the transverse rod 5 corresponds to the distance between the parallel internal
    5 by the sides of the side rods 3 of the U-shaped plate 1.
    In addition, the T-shaped plate 2 with its longitudinal rod 6 on one side adjacent to one pair
    0 side rods 3, oppositely located
    a row of i-shaped plates 1, and on the other side - to a longitudinal rod
    6 adjacent .J opposite T-shaped plate 2. Thus, between
    5, two rods 3 of the U-shaped plate 1 of the same row, two side rods 3 of two U-shaped plates 1 of the opposite row and two longitudinal rods 6 of the two plates 2
    0 reverse closure, located mirror relative to each other.
    Cutting lines (fig. 2) between separate U-shaped 1 and .T.-shaped 2 plates of evidence
    The fact that all the plates are cut from the tape without waste in the direction along the tape. The side bars of the 3 U-shaped plates 1 can be of any width, as well as the height of the plates.
    1 and 2, i.e. The design height can be determined by selecting the appropriate tape width without any restrictions and adapted to any requirements.
    On the side rods 3 of the O-shaped plates I, profiled cuts 12 are formed on the outside, which serve to place a hold-down tire in the finished throttle, compressing the side rods 3. In addition, the longitudinal rods 6 of the T-shaped plates 2 are re-closed due to the remaining between them , jumper 3 is shortened, as a result of which get throttles with an air gap 7 (Fig. 1)
    In order that the T-shaped plates 2 can be inserted with a thrust between the side rods 3 of the U-shaped plates 1, the plates 2 can be somewhat longer than the distance between the inner sides of the side rods 3 of the U-shaped plate 1. For this, it is advisable at the ends transverse rods 5 stamp small rectangular protrusions 14, which are 2 / 100-3 / 100 mm long, and their height is less than the height of transverse rods 5 along its length corresponding to the distance between the inner sides of the side rods 3 and the -shaped plate 1 Besides oh, the end sides of the transverse rods 5 of the T-shaped plates 2 can be cut with a small bevel 15 (Fig. 1) in the direction towards the middle stem 6, which, together with the maximum length of the transverse stem 5, slightly exceeds the distance between the inner the sides of the side rods 3 of the U-shaped plate 1, provides insertion of the transverse rod 5 with the expansion of the rods between the side rods 3. The difference between the maximum and minimum lengths on the outer and inner edges of the transverse rod is on each end of the order of 2 / 100-3 / 100 mm.
    The cutting pattern (Fig. 2) in the form of a strip can correspond to the width of the tape from which the cutting is made.

    ka However, it is advisable to locate several such strips adjacent to each other across the width of the tape, i.e. , stamp from a correspondingly wider tape.
