In addition, the holding convex portion 12b may be rectangular, and the two H of the residual portion 12 may be fitted and fixed to the back portion 1U of the core portion 11 and sandwiched. The convex portion 12b may be formed in a concave shape by the fixing portion of the manufacturing apparatus and the central portion 12c. With this shape, the contact portion between the sheet bundle I2 and the outer peripheral portion of the iron portion 11 can be reduced. Further, it can be surely fixed to the fixing portion of the manufacturing apparatus. In order to reduce the G contact area with the fitting portion of the fitting recess 11c of the f-magnetic portion 11a, the detaching recess 12f is provided at a predetermined position/shape at the end of the rear convex portion 残 of the residual portion 12. The detachment recessed portion 11f may be provided at the end of the fitting recessed mountain side. In the first drawing, the fitting portion surface is punched in a hole shape, and the detachment recess portion and the detachment recess portion Ilf are provided at each of both sides of the fitting convex portion i2a and the fitting recess portion lie. , lg, nh examples. The fixing recess 12d and the fixing projection l2e are provided on the front and back surfaces of the debris piece 12, respectively. When the iron core 5 is laminated, the fixing recesses and the fixing portions 12e' corresponding to each other by the residual portion 12 adjacent to each other are fixed in the lamination direction. The residual portion 12 which is fixed by lamination and staking is formed as a fixing aid for temporarily fixing the laminated core portion 11 in a laminated state. The core portion 11 temporarily fixed by the fixing aid is formed by solid bonding to form a laminated core. Fig. 2 is a view showing the shape of the insulating resin 13 by compression molding (die•(10) cell g) in the form of temporary bonding by the fixing aid 12(), and the layer is actually fixed. Iron core 110. In the fixing aid 12G, the holding convex portion (the laminated convex portion i2b which has been laminated) is fixed in the laminating direction by the caulking, so that the insulating resin can be firmly fixed in the molding step and the winding step. In the meantime, the laminated iron portion 110b is fixed to the lateral direction of the laminate, and the laminated iron anger 110 (the laminated core portion n) is temporarily fixed. After the laminated core 110 and the insulating resin 13 are integrally formed and wound, the fixing aid 120 is slid in the lamination direction (direction A in FIG. 2), and is removed from the concavity recess Uc of the back magnet portion Ua. . Since the fixed auxiliary assisting device 120 has a columnar shape with a butterfly cross section in the axial direction of the laminating direction, and the central portion 12GC has a concave shape which is tapered at the center, it does not contact the outer peripheral surface of the laminated core no. The outer peripheral surface is deformed so that it can be easily removed. In addition, the fixing assisting device 120 is a detaching groove portion 12〇f, i2〇g, (the detached recess portion 12f, 12g which has been laminated) by the fitting convex portion 120a (the laminated rear convex portion 12a) (12h), and the detachment groove portion of the rear end of the laminated iron wrath 110 (the laminated recess He is laminated), ^, 1 (10) (the recessed portion 321740 9 201037944 lh) The contact area between the end portion of the convex portion 120a and the white portion and the end portion of the fitting concave portion c can be easily removed by elastically deforming the end portion of the fitting convex portion 12Ga and the end portion of the reference concave portion UGe. , the person is fixed in the layered lining U 〇, in the removal of the fixed aid is slightly round ^ 11 〇 a (the layered back magnetic part called a garment-like way to connect a plurality of laminated core n〇, and The tooth portion (10) is protruded in the center direction of the ring ο: side (the teeth 2 which have been laminated) constitute the stator 2〇〇 shown in Fig. 3. Next, the laminated core 11 of the first embodiment is described. The manufacturing method of Fig. 4 shows the step of punching the steel sheet using a punch mask. As shown in Fig. 4, 'the punching step is performed in the order of the downward direction of the arrow B'. The 4th _ oblique line indicates the passage. The die-cut part. Figure 4) shows the initial steps, and Figure 4 (7) shows the last step. The direction shown by the arrow c in the left direction is the die-cut iron chip 5 after punching.首先. First, in the step of Fig. 4(a), a thin steel plate 14 made of a magnetically steep material such as an electromagnetic steel sheet is punched into a positioning (Pil0t) hole 15 which serves as a positioning reference in the punching process. Steel plates with a thickness of 〇.2mm f 〇.5mm can be used. When one step is completed, the steel plate 14 is successively used as a boring hole. The predetermined size between 15 is transported, and the process proceeds to the next step. ^ Next, in the step of Fig. 4(b), punching is performed to form the detaching recessed portion based on the boring hole 15 formed in the steel sheet 14 as a reference. 12f, 12莒, l2h and the separation holes 16f, 16g, 321740 10 201037944 I6h of the recesses Ilf, 11g, and Uh for detachment. Next, in the step of Fig. 4(c), the punching is used to cut out = the outer periphery of the portion of the nip portion (10) of the portion 12 and the region 17 of the peripheral portion of the periphery of the ridge recess portion 11c of the back magnetic face portion. Next, in the step of Fig. 4(d), the residue is The front surface and the back surface of the center portion of the holding boss 12b of the portion 12 are provided with a fixing recess 12d and a fixing convex portion i2e for fixing the laminated iron core 5 by crimping, respectively, by press working. Then, in the step of (e) of FIG. 4, the region of the residual portion 12 is pressed back, and after the fitting convex portion 12a of the residual piece portion 12 is punched out, it is pressed back to the fitting concave portion. The fitting convex portion 12a of the residual portion 12 is formed, and the detachment holes 16f, 16g, 16h' are formed at the same time. The recessed portions 12f, 12g, and 12h and the recesses for detachment 1 If, 1 lg, and 1 are formed. Next, in the step of (f) of FIG. 4, the outer shape of the core portion n is punched, and the outer shape of the core portion n is cut. The fitting convex portion 12a of the sheet portion 12 is fitted and fixed to the core piece 5 of the core portion of the fitting recess portion 11c of the back yoke portion 11a (in the direction of the arrow C). Similarly, by the fourth drawing In the steps (a) to (f), the cutting and crimping of the core piece 50 are repeated, thereby laminating a desired number of pieces of iron chips (5〇-Bu 50-2.....5〇-n The fixing recesses 12d and the fixing projections I2e of the adjacent iron cores are fixed, and the laminated core 11〇 temporarily fixed by the fixing aid 120 is obtained. Further, in the step ♦ of FIG. 4(d), the first layer of the iron core 50-1 and the last* layer of the iron core 50-n which are temporarily fixed by the fixed auxiliary device 12〇321740 11 201037944 The fixing recess 12d and the fixing convex portion 12e or the fixing concave portion and the fixing convex portion 12e are formed only on the inner side in the lamination direction, whereby the laminated core 110 temporarily fixed by a desired number of sheets can be obtained, and Since the laminated cores 110 are not fixed to each other, the laminated core 110 can be continuously obtained. Then, the laminated core 110 which is temporarily fixed by fixing the auxiliary tool 120 is fixed to the mold of the forming machine while the holding convex portion 120b is held. The laminated core 110 is integrally molded by die-casting, and as shown in Fig. 2, the tooth portion 110b (the tooth portion lib which has been laminated) and its peripheral portion are covered with an insulating resin 13, thereby being virtually fixed. As shown in Fig. 5, the laminated core 110 which has been actually fixed is held by the holding convex portion 120b of the fixing aid 120 in the fitting state by the holding portion 31 of the winding machine 300, and is formed in a circular orbit. The nozzle 32 of the winding machine 300 is rotated around the circumference of the tooth portion 11 Ob, whereby the winding 18 is wound around the tooth portion 110b of the laminated core 110 covered with the insulating resin 13 (the toothed portion having been laminated) Lib). Fig. 6 is a cross-sectional view showing the laminated core 110 which has been actually fixed after winding. After the winding, the fixing assisting device 120 is slid from the fitting concave portion 110c of the laminated core 110 in the lamination direction (direction A in Fig. 2) and removed. The laminated core 110 having the fixed auxiliary aid 120 removed is connected to the back yoke portion 11a, and the toothed portion 110b is protruded from the center of the annular inner side. The stator 200 shown in Fig. 3 is obtained. As described above, in the first embodiment, in the state in which the fixed auxiliary device 120 of the butterfly type is temporarily fixed by the product direction cross section 12 321740 201037944, the laminated core 110 is actually fixed and is After the fixing is actually fixed, the fixing aid-120 is removed, and since the central portion between the fitting portion and the holding portion of the fixing aid is a concave shape which is tapered in the middle, it does not come into contact with the outer peripheral surface of the laminated core. The outer peripheral surface is deformed, and the fixing aid can be easily removed. Further, when the stator is formed, even if the laminated core is pressed into the frame in order to maintain the shape and position, the outer peripheral surface is not deformed, and the assembly property with the frame and the roundness of the stator can be improved. In addition, by using the fixing aid 120 having a butterfly-shaped cross-section in the laminated direction, it can be easily held by the manufacturing apparatus, and the laminated core can be surely restrained and fixed even in the lateral direction of the laminate. Further, since the true fixing means of the laminated iron core does not use welding, and the stator having no staking portion can be manufactured, the iron loss of the product can be reduced. In addition, there is no difficulty in the use of the actual fastening means in the case of the next, and there is no problem of reducing the fill factor of the laminated core. Q (Embodiment 2) In the method for manufacturing a laminated core according to the first embodiment, the laminated core 110 temporarily fixed by the fixing aid 120 is integrally molded by the insulating resin 13, thereby realizing the solid state. The situation is connected. On the other hand, in the second embodiment, it is shown that the molded article of the insulating resin is placed in the laminated core and wound, thereby being virtually fixed. Fig. 7 is a perspective view showing a step of coating a molded article of an insulating resin in a method of manufacturing a laminated core according to a second embodiment of the present invention. In the method of manufacturing a laminated core according to the second embodiment, the holding convex portion 120b is held by the fixing assisting device 31 of the wire cutter 300, which is shown in Fig. 5, and the first embodiment is used. 4 The temporarily fixed-state laminated core 110 obtained by the steps of (a) to (f) is fixed. Then, the laminated core 110 in the temporarily fixed state is fitted into the tooth portion 110b from the upper and lower sides to the tooth portion 110b in a state in which the sandwiching convex portion 120b is sandwiched. And its peripheral portion, and the winding 18 is wound therefrom, thereby being virtually fixed. The molded articles 19 and 20 of the insulating resin restrain the laminated transverse direction of the laminated core 110, and the winding 18 is restrained in the lamination direction and further strengthens the fixing in the lateral direction. Further, in the second embodiment, the covering of the molded articles 19 and 20 of the insulating resin and the application of the winding 18 are actually fixed, but the molded article 19 and the molded article of the insulating resin are provided with the insulating resin on the upper and lower sides. When the fitting portion is provided in the portion to be joined to each other to restrain the lamination direction, the covering of the molded articles 19 and 20 of the insulating resin can be truly fixed. As described above, in the second embodiment, the molded articles 19 and 20 in which the insulating resin is formed in advance are wrapped in the temporarily fixed state laminated iron in a state in which the holding convex Q portion 120b is held. Since the core 110 is thereby firmly fixed, the forming process of the insulating material can be performed in parallel without forming a laminated core during the molding of the insulating resin, so that it is not necessary to in-line the large molding machine. The stator manufacturing line can be operated without being affected by the insulator forming step with a long process time. Further, in the first embodiment and the second embodiment, the method of manufacturing the laminated core of the split type stator will be described, but the present invention is not limited thereto. For example, it can also be applied to the construction of a connected stator, an articulated stator, and a 14321740 201037944 integrated stator. 8 to 10 are front views showing the coupled stator core 201, the closed stator core 202, and the integrated stator core 203, respectively. In any of the laminated cores 110, the same effect can be obtained by providing the fixed auxiliary aid 120 (the residual portion 12 of the laminated layer) having a butterfly-shaped cross section in a predetermined direction. (Embodiment 3) In the method of manufacturing a laminated core according to the first embodiment, the fitting recess is formed from the back yoke portion 11a by merely sliding the fixing aid 120 in the lamination direction after the positive fixing is performed. 11c removed the situation. On the other hand, in the third embodiment, the fixing aid is removed and the fixing aid is slid and removed after the processing force required for the removal of the fixing aid is lowered. Fig. 11 is a plan view showing an example of an iron core according to a third embodiment of the present invention. Fig. 12 is a view showing that the iron core 110 shown in Fig. 11 is formed in the same manner as in the first embodiment, and the laminated iron core 110 is pre-fixed and wound by the Q, and the fixing aid 120 is removed. An oblique view of a part of the process (not shown in the winding). First, the configuration of the iron core according to the third embodiment will be described using Fig. 11 . In the core piece 51, a detachment hole 26 for releasing the fitting state is provided between the entire end surface 12i of the fitting convex portion 12a of the residual piece portion 12 and the fitting concave portion 11c of the back yoke portion 11a. The detachment holes 16f, 16g, and 16h in the first embodiment are replaced. The other components are the same as those in the first embodiment, and the same reference numerals will be given to the same portions, and the description thereof will be omitted. 15 321740 201037944 In this way, the portions of the core piece 51 in which the residual portion 12 and the back yoke portion 11a are in the state of being fitted and fixed are the fitting faces 12j and 11j and the fitting faces 12k and Ilk, and the fitting is transmitted through these fittings. The fixing concave portion 12d and the fixing convex portion 12e which are provided on the front surface and the back surface of the residual portion 12 are crimped when the iron core 50 is laminated, whereby the iron core 51 is fixed in the lamination direction. Next, a method of removing the fixing aid 120 (the residual portion 12 of the layered layer) is shown using Figs. 11 and 12. First, the fixed iron core 110 (the laminated core portion 11) is pressed from the side of the back yoke portion 11a toward the tooth portion lib side, that is, toward the inside of the laminated core 110. The radial direction (the B direction in Fig. 11 and Fig. 12) is pressurized. Fig. 12 is a view showing a state in which the fixed assisting device 120 relatively moves in the inner diameter direction with respect to the laminated core 110 after the pressurization. As shown in Fig. 12, the fixing assisting device 120 can be relatively moved in the inner diameter direction by the detaching hole 26, and a gap can be formed between the fitting surfaces 120j and 110j and the fitting surfaces 120k and 110k 而 to cancel the insertion. State. Then, after the fixing assisting device 120 is relatively moved in the inner diameter direction with respect to the laminated iron core 110, the fixing assisting device 120 is slid toward the laminated direction of the laminated iron core 110 (the Α direction of Fig. 12). Since the fixing assisting device 120 can be slid in the laminating direction of the laminated core 110 with almost no force, the fixing assisting device 120 can be easily removed from the laminated core 110. Further, as shown in Fig. 11, by providing the blade portion 12 in a butterfly shape, the fitting surface 12j and the fitting surface 12k of the fitting convex portion 12a are fitted by the fitting surface 11j of the back yoke portion 11a and The fitting surface Ilk is fixed in the outer diameter direction, and even 16 321740 201037944 is opposed to the laminated core 110 in the direction of the outer diameter of the iron core with respect to the laminated core 110 (in the opposite direction to the arrow B of the first and fourth figures) The power of ', can also maintain the above-mentioned comrades by the geometric constraints. With this effect, in the manufacturing process of the stator including the step of mounting the insulator to the laminated core 110 and the winding step, the laminated core 110 and the fixing aid 120 need not be disassembled, and the laminated core 110 can be fastened. Secure to the device or aid. As described above, in the third embodiment, the detachment hole 26 is provided between the end portion of the fitting convex portion 12a of the residual portion 12 and the fitting concave portion 11c of the back yoke portion 11a. Since the auxiliary tool relatively moves in the inner diameter direction and a gap is formed between the auxiliary tool and the back yoke portion, the fitting state can be easily released. Further, with this gap, the fixing aid can be easily detached from the laminated core by the force of the fixing aid in the laminating direction of the laminated core. Further, by providing the residual portion 12 as a butterfly type, the fitting state can be maintained even if a force in the outer diameter direction of the laminated core acts on the fixing aid. Further, in the manufacturing process of the stator including the step of mounting the insulator to the laminated iron core and the winding step, the laminated core can be securely fixed to the device or the auxiliary device without disassembling the laminated core and the fixing aid. . Further, in the third embodiment, a method of manufacturing the laminated iron core of the split type stator will be described, but the method is not limited thereto. For example, it can also be applied to the manufacture of a connected stator, an articulated stator, and an integrated stator. In the laminated core 10 shown in Figs. 8 to 10, the cross section of the layer having the detachment hole 26 is formed in a butterfly shape by the position of the pre-17 321740 201037944.
