Abstract

PURPOSE:To effectively utilize extreme outside circumference silicon steel plates by a method wherein respective cutoff sections of a belt-shaped extreme outside circumference silicon steel plate formed the cutoff sections and connection sections at opposite end sections respectively by slits notched in the longitudinal direction are welded. CONSTITUTION:Cutoff sections 1c, 1d and connection sections 1e, 1f are formed by forming slits 1a, 1b notched in the longitudinal direction respectively at the opposite end sections of an extreme outside circumference silicon steel plate 1. Respective cutoff sections 1c, 1d are welded by rolling the steel plate 1. Next, a plurality of silicon steel plates 2 are stacked in the inside of the ring steel plate 1 to form a wound core. After formation and annealing, a spot welding section B is removed to cutdown the cutoff sections 1c, 1d. Next, both end sections A of the steel plates 1, 2 are opened to insert windings 3 in the steel plates 1, 2 and both the end sections A are faced again. After that, spot welding is applied to respective connection sections 1e, 1f of the steel plate 1 to clamp the steel plate 2.

Description

[Detailed Description of the Invention] The present beak is produced using cut-shaped wound core manufacturing method 4C! 11 and 9 designed to reduce manufacturing costs.

Based on the conventional cut-shaped iron core OII manufacturing method Diagram 1! To be clear, first, a silicon steel plate t cut to a specified size is rounded and the ends are spot welded to each other to create the outermost silicon steel plate 1tl1 of the award shown in Fig. 1-). Of the nine pieces of silicon steel Ij2 each cut to a predetermined size, the long one is aligned with the center of each other to make it endless and in good shape, the maximum amount of scrap silicon 111 is obtained.
11jlO are laminated one after another along the inward direction to obtain the wound core assembly shown in Figure 1). By hanging, the wound core shown in IWA) was formed and annealed, and spot melted as shown in 111Ellall&), 伽)! Remove part I and B, open the end part and complete 1.
Insert east as shown in Figure Q). At this time, the outermost silicon steel plate 1 [1a] is removed from the silicon steel 4 [2] and thrown away. This is because the outermost silicon steel plate 1 will be damaged. After this, the two ends of the laminated silicone are brought together and closed.
By tightening with i-band 4, $1. As shown in the IEIII button, the O'&O band 4, on which the winding weight 3 is attached to obtain a nine-cut wound core, is connected at both ends with a sealing material 5.

However, in this conventional technique, the outermost silicon steel plate 1 is discarded, resulting in high cost and uneconomical costs.

Based on the above-mentioned prior art, the purpose of this project is to provide a method for manufacturing a cut-shaped wound core that can reduce manufacturing costs. A cutout part and a connection part are formed at both ends by 9 slits, respectively, and the cutout parts of a round band-shaped outermost silicon steel A steel plate are welded together to form an annular outermost silicon steel plate. Sakushi,
Next, 1,111 silicon steel plates with the innermost edges of the outermost silicon steel plates butted against each other are laminated, formed, annealed, and then removed from the cutout section, and this cut section ta* is discarded and further removed. After aligning the ends of each other by tl1%/% and inserting the shaft, center the gIA parts again and tighten the thick steel plate to the outermost part of K11l.
One feature is that the connecting parts of the silicon steel plates are in contact with each other by 1 m.The embodiments of the present invention will be explained in detail below based on 111iK.In addition, the same parts as the conventional technology KFi are given the same symbol.
Duplicate explanations will be omitted.

Figure 2)~#I21! l←) shows an example of the method of the present invention. Among these, the outermost silicon steel 4 [IK shown in $ 112114) has 9 slits cut in the longitudinal direction on both 1111 and 9 slits 1&#IThK> truncated s1!111 and *! ! ill@, 1f and $ are formed and tail.

First, the outermost silicon steel plate 1t is rolled up and the cut-off portions 1c and lsl are spot welded together to form an annular outermost silicon steel plate 1tl1 as shown in Figure 2).

Next, in the same manner as before, a plurality of silicon steel sheets 4 [2] are laminated on 11 of the outermost silicon steel plates 1 to create a wound core as shown in Fig. 2←), and this wound core is tg carved and annealed. Then round down 11

Note that since the slits la and lb are cut in advance, the work of cutting off the cut-off portions 1a and 1 (Lt) can be easily done.After that, as in the past, the outermost silicon steel plate 1 and the silicon steel plate 2aSS are opened and rolled. 13, and again butt the end tubes against each other.Then, as shown in Fig. 2 (8), the outermost silicon steel 1:1!

By spot welding lf to each other, a silicon steel plate 2tMF plated cut type wound core is manufactured using the outermost silicon steel plate IK. According to the present invention, as explained in KA with the above embodiments, In order to make the outermost silicon steel plate into an annular shape, the cut-off parts formed at both ends 11 were welded together, and after the forming and annealing work, the welding edge XI was removed and damaged.

Let's move on to the rest of the end at WC! By welding the I joints together, it is possible to tighten the silicon steel plate with the outermost silicon 1A IIIA plate.By simply cutting off the cutout S, the outermost silicon steel I can be effectively used. Therefore, we hope to significantly reduce the construction cost compared to the VL technique, which used to completely discard the waxed outer silicon steel plate. Of course, there is no need for sealing material in the band, which was rarely needed in the past.9 Furthermore, manufacturing costs are reduced.Since the connecting parts are connected by the housing S, the outermost periphery is made of silicon-I. The silicon steel plate is securely tightened.
