[0035] The utility model discloses a kind of thin rivet point-free iron core structure and the separating tool for the iron core structure.
[0036] Embodiment one:
[0037] Refer to Figures 1 to 7 A kind of thin rivet point-free iron core structure, including two outer frames 1 and the silicon steel sheet 2 between two outer frames 1, separating groove 11 is equipped between two outer frames 1, silicon steel sheet 2 includes integrally-formed connecting portion 21 and separating portion 22, connecting portion 21 is connected with two outer frames 1 simultaneously.
[0038] Specifically, the two sides of the connecting part 2 are provided with a first clamping surface 23 and a second clamping surface 24, and each outer frame 1 is provided with a first connecting surface 12 matched with the first clamping surface 23 and a second connecting surface 13 matched with the second clamping surface 24. The first connecting surface 12 and the second connecting surface 13 are obliquely arranged, that is, the connection between the outer frame 1 and the silicon steel sheet 2 is not only in one direction, thereby improving the connection strength of the outer frame 1 and the silicon steel sheet 2, so as to adapt to thinner silicon steel sheets 2. Because the silicon steel sheet 2 and the outer frame 1 need to be semi-shear punched, if the combination of the outer frame 1 and the silicon steel sheet 2 is only in one direction, the combination strength is limited, and when semi-shear punching, the thinner silicon steel sheet 2 may be directly separated from the outer frame 1.
[0039] More specifically, the first connecting surface 12 is provided with a connecting groove 121, and the first clamping surface 23 is provided with a connecting protrusion 231 matched with the connecting groove 121.
[0040] The second connecting surface 13 is provided with a first protruding part 14 and a first recessed part 15, the second clamping surface 24 is provided with a second recessed part 25 matched with the first protruding part 14, and the second clamping surface 24 is further provided with a second protruding part 26 matched with the first recessed part 15. Through the cooperation of the first protruding part 14 and the second recessed part 25 and the cooperation of the second protruding part 26 and the first recessed part 15, the connection strength of the silicon steel sheet 2 and the outer frame 1 is further improved, and the processing of thin materials is further adapted.
[0041] A separation tool includes a template 31, a positioning piece 32 and a separation piece 33. The positioning piece 32 is arranged on the template 31 and is adapted to position the silicon steel sheet 2 and the outer frame 1. The separation piece 33 is adapted to be inserted into the separation groove 11 to separate the outer frame 1 from the silicon steel sheet 2. The template 31 includes a bottom plate 311 and a separation positioning plate 312. The positioning piece 32 is installed on the bottom plate 311, and the separation piece 33 is installed on the separation positioning plate 312. The bottom plate 311 is connected with a guide column 313. When the bottom plate 311 and the separation positioning plate 312 are folded, the separation positioning plate 312 is penetrated by the guide column 313.
[0042] A first positioning groove is arranged between the two outer frames 1 and the silicon steel sheet 2, and the first positioning groove is concave. The separation groove 11 is arranged at one end of the connecting part 21 away from the separation part 22. The positioning piece 32 includes a first positioning block 321, which is inserted into the first positioning groove. The first positioning block 321 is provided with a limiting groove 3211 for inserting the separation part 22, and the separation part 22 is matched with the limiting groove 3211. The separation piece 33 includes a first separation block 331, which is used for inserting the separation groove 11 to separate the two outer frames 1 from the connecting part 21.
[0043] The first separating block 331 comprises a fixed part 3311 and a working part 3312 which is integrally formed, the working part 3312 is suitable for being inserted into the separating groove 11, the fixed part 3311 is fixedly connected with the separating positioning plate 312, and two avoiding bevels are arranged at the end of the fixed part 3311 which faces the working part 3312, the distance between the avoiding bevels and the end of the working part 3312 which is away from the fixed part 3311 gradually increases along the direction from the middle to the edge of the fixed part 3311, so as to avoid interference when the two outer frames 1 are separated. The width of the working part 3312 is slightly greater than the width of the separating groove 11, so that the outer frame 1 and the silicon steel sheet 2 can be separated when the working part 3312 is inserted into the separating groove 11. The bottom of the working part 3312 is integrally formed with a first guide cone part, and the width of the small end of the first guide cone part is smaller than the width of the separating groove 11, so that the working part 3312 can be inserted into the separating groove 11.
[0044] When the outer frame 1 and the silicon steel sheet 2 are separated by the separating tool 3, the integrated silicon steel sheet 2 and the outer frame 1 are first placed on the bottom plate 311, and the separating part 22 is inserted into the limiting groove 3211, then the separating positioning plate 312 is folded with the bottom plate 311, so that the working part 3312 is inserted into the separating groove 11, so that the two outer frames 1 are rotated away from each other to separate the silicon steel sheet 2. Compared with the mode of moving the two outer frames 1 away from each other to separate, the mode of rotating the silicon steel sheet 2 and the outer frame 1 apart can facilitate the separation between the first recess 15 and the second protrusion 26, and the separation between the second recess 25 and the first protrusion 14.
[0045] Embodiment two:
[0046] Reference Figures 8 to 11 The difference between the embodiment 1 and the embodiment 2 is that each silicon steel sheet 2 corresponds to two separating grooves 11, and the separating groove 11 is located between each outer frame 1 and the separating part 22. At the same time, the second connecting surface 13 is not arranged on the outer frame 1, so that a plurality of silicon steel sheets 2 can be arranged between every two outer frames 1, and the plurality of silicon steel sheets 2 are arranged along the length direction of the outer frame 1, and the number of the silicon steel sheets 2 in the embodiment is three. In other embodiments, the number of the outer frames 1 can be increased along the width direction of the outer frame 1, and a group of silicon steel sheets 2 are arranged between the adjacent two outer frames 1, but it is easier to control the precision when only two outer frames 1 are used.
[0047] The positioning member 32 comprises four second positioning blocks 323, which form a positioning area for preventing the silicon steel sheet 2 and the outer frame 1, and the second positioning blocks 323 are L-shaped to position the outer frame 1 and the silicon steel sheet 2 as a whole. The separating member 33 comprises two second separating blocks 332, each of which is adapted to be inserted into a corresponding separating groove 11 to separate the two outer frames 1 from the connecting portion 21. The second separating blocks 332 are adapted to the inner side wall of the outer frame 1. A gap is left between the outer frame 1 and the second positioning blocks 323 along the connecting line direction of the two second separating blocks 332 to separate the two outer frames 1 from the silicon steel sheet 2. Meanwhile, the second positioning blocks 323 also facilitate the positioning of the separated outer frame 1 and facilitate the collection of the separated outer frame 1. The bottom of the second separating block 332 is integrally formed with a second guide cone portion, and the width of the small end of the second guide cone portion is smaller than the width of the separating groove 11 to be able to be inserted into the separating groove 11.
[0048] When the outer frame 1 is separated from the silicon steel sheet 2 by the separating tool 3, the integrated silicon steel sheet 2 and outer frame 1 are placed on the bottom plate 311, and the two outer frames 1 are located between the four second positioning blocks 323. Then, the separating positioning plate 312 is folded with the bottom plate 311, so that the second separating blocks 332 are inserted into the separating grooves 11 to move the two outer frames 1 away from each other to separate the two outer frames 1 from the silicon steel sheet 2. Compared with the mode of moving the two outer frames 1 away from each other to separate, the second positioning blocks 323 also facilitate the blocking of the separated outer frame 1 to prevent the outer frame 1 from falling on other positions of the mold.
[0049] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
