Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exciting annealing system, a carrying tray, and an exciting annealing furnace, which are attached to a carrying tray when an object to be processed such as a winding core made of an amorphous alloy is subjected to exciting annealing. The present invention relates to a high-efficiency excitation annealing system in which a current is stably applied to a wound iron core loaded on a transfer tray through a tray power receiving terminal, a penetration excitation annealing electrode, a transition conductor bar, etc. to generate a magnetic field to perform excitation annealing.

[0002]

2. Description of the Related Art A wound core made of an amorphous alloy must have magnetic properties. As a method thereof, as shown in FIGS. 6 and 7, the wound iron core 1 is placed on a dedicated transfer tray 2 and the transfer tray 2 is transferred into an exciting annealing furnace. After the loading, the energizing electrode 8a on the side wall of the excitation annealing furnace is advanced to the tray power receiving terminal 5 attached to the side surface of the transport tray to move the electrodes 5, 8a.
Contact each other. Then, the inside of the excitation annealing furnace is vacuumed,
After enclosing an inert gas, a current is passed through the current-carrying electrode 8a to generate a magnetic field in the wound iron core 1 via the tray power receiving terminal 5, the penetration excitation annealing electrode, and the transition conductor bar 7, and for a predetermined time,
Excited and annealed.

[0003]

Since the conventional exciting annealing furnace is a vacuum furnace, the energizing electrode 8a on the side wall of the exciting annealing furnace is used.
The mounting position of was fixed. Further, the tray power receiving terminal 5, the penetration excitation annealing electrode, and the transition conductor bar 7 attached to the transport tray 2 were also fixed so as to be aligned with the position of the energizing electrode 8a on the side wall of the excitation annealing furnace.

There are various kinds of wound iron cores of various sizes, and it is very wasteful to individually use a transport tray. Therefore, a tray power receiving terminal 5, a through-excitation annealing electrode, and a transfer tray 2 for the transition conductor bar 7 which are arranged at a certain interval are used, and the winding iron core 1 is placed on the tray 2 and is transferred to an excitation annealing furnace to be excited and annealed. Was.

However, since there are many kinds of wound iron cores 1, when a tray for receiving electricity, electrodes for through excitation annealing, and transition conductor bars are arranged at a fixed interval, a transport tray is used, the winding is matched to the interval. If the iron core has a good loading rate, other winding cores such as small winding cores, large winding cores, etc. that do not match the intervals will be loaded on the transport tray, and the loading rate will deteriorate, and the energy source due to excitation annealing will be reduced. There was a problem that the unit would be high. In addition, the recent production system has changed from small-lot mass-productivity to multi-item small-lot productivity, and it has been forced to mix different models on the tray for transporting the same processed object. However, as described above, in the case of the fixed tray power receiving terminal and the tray for carrying the electrodes for penetration excitation annealing, if different models are mixed, a lot of wasted space will be generated, and the loading rate will deteriorate, and this will also cause There is a problem that the energy consumption rate due to annealing increases.

In order to solve the above problems, an object of the present invention is to provide an exciting annealing system capable of increasing the loading rate of a transport tray for a large number of small quantities of various products and reducing the energy consumption rate due to the exciting annealing. It is to provide a transfer tray and an excitation annealing furnace.

Excitation annealing. The energizing electrode 8b is of a wide type that transmits an exciting current to the tray power receiving terminal 5 of the carrying tray 2.

In the first embodiment, an example of a stacking method on the transfer tray in the excitation annealing system will be described.
When exciting annealed wound cores having the same shape, the wound cores are arranged on the transfer tray 2 for processing. The arrangement method is the same as that of the conventional example (see FIG. 6), and the description thereof will be omitted.

Next, when exciting annealing of various types of wound cores, as shown in FIG. 1 as an example of stacking, various types of wound cores 1 are placed on a transport tray 2. In the excitation annealing system of the present embodiment, it is possible to carry out such loading, and it is possible to carry out excitation annealing without reducing the loading rate. The details will be described below. First, consider an arrangement in which the wound iron cores 1 loaded on the transport tray 2 can be loaded at the best loading rate. Depending on the arrangement, the tray power receiving terminal 5, the penetration excitation annealing electrode 6, and the transition conductor bar 7 are set up.

The tray power receiving terminal 5 is, as shown in FIG.
It is attached to the side surface 9 of the transport tray so as to be slidable in the tray insertion direction, and moves each tray power receiving terminal 5 to the left or right (indicated by an arrow, tray insertion direction) according to the lateral size of the winding core 1. After that, the tray power receiving terminal slide base 12 is pinched by the tray power receiving terminal applying plate 13 and fixed so that the tray power receiving terminal 5 does not move.

As shown in FIGS. 2 and 3, the penetration excitation annealing electrode 6 moves forward and backward (indicated by an arrow) according to the size of the wound core 1 in the longitudinal direction, and thereafter, for penetration excitation annealing. The electrode slide base 10 is scissored with the electrode plate 11 for penetration excitation annealing (see FIG. 3A), and the electrode 6 for penetration excitation annealing is fixed so as not to move (see FIG. 3B).

The method of supplying current to the tray power receiving terminal 5 and the penetration excitation annealing electrode 6 of this embodiment is as follows.
It was a method of scissoring 0 and 12 with the respective contact plates 11 and 13, but in addition to this, a method such as a brush is used to ensure the tray power receiving terminal 5 and the penetration excitation annealing while maintaining the insulation with the tray for transportation. Any method of supplying a current to the electrode 6 can be adopted.

The wound core 1 is piled up to a predetermined height by passing the electrode 6 for through excitation annealing. Then, in order to apply a current to the penetration excitation annealing electrode 6, the penetration excitation annealing electrodes 6 are connected to each other by a crossover conductor bar 7. At this time, the penetration excitation annealing electrodes 6 have different angles depending on the arrangement of the wound core 1.
The distance is different. Therefore, for the angle adjustment, as shown in FIG. 4, the penetration excitation annealing electrode 6 is formed into a columnar shape (see FIG. 4A), and the connection between the transition conductor bar 7 and the penetration excitation annealing electrode 6 is formed into a columnar shape. The transition conductor bar 7 processed into a semicircular shape and the transition conductor application plate 14 processed into a semicircular shape are scissors-fixed and fixed to the through excitation annealing electrode 6 (see FIG. 4B).

Regarding the distance between the electrodes 6 for penetration excitation annealing, as shown in FIG. 5, the transition conductor bar 7 is subjected to screw processing, slotted hole processing, etc. so that the length of the transition conductor bar 7 can be adjusted. . As a result, it is possible to handle any angle and distance and to pass a stable current.

The current supply method for the rotating transition conductor bar 7 and the penetration excitation annealing electrode 6 of this embodiment is a method of sandwiching the penetration excitation annealing electrode 6 between transition conductor application plates 14 processed into a semicircular shape. However, in addition to this, the conductor bar 7 and the through-excitation annealing electrode 6 are surely applied by a method of passing an electric current through a rotating object.
Any method of supplying an electric current can be adopted.

The exciting annealing furnace 3 in the exciting annealing system of the embodiment will be described with reference to FIG. Excitation annealing furnace 3
The furnace wall 4 is provided with a wide-type energizing electrode 8b for transmitting an exciting current to the tray power receiving terminal 5 of the carrying tray 2. The energizing electrode 8b is elongated in the lateral direction of the electrode, and as described above, even if the tray power receiving terminal 5 is arranged at a shifted position, the energizing electrode 8b and the tray power receiving terminal 5 are separated from each other. It becomes possible to make contact, and the exciting current can be reliably flowed.

As described in the above embodiments, the present invention has a structure in which the tray power receiving terminal attached to the carrying tray is movable in the left-right direction, and the penetration excitation annealing electrode is movable in the front-rear direction. Further, the crossover conductor bar connecting the electrodes for penetration excitation annealing is also capable of following this movement. Further, in the excitation annealing furnace, even if the tray power receiving terminal attached to the transfer tray is moved to any position, the tray is surely contacted and a stable current can be supplied.
