1：检查铁芯，将合格的铁芯吊至手推车上，用水果刀打开铁芯搭接，并用吸尘器将铁心开口处非晶碎片吸净。
1: Check the iron core, hang the qualified iron core to the trolley, open the iron core lap with a fruit knife, and use a vacuum cleaner to clean the amorphous debris at the opening of the iron core.
2：选择相应型号的铁芯护套，插入铁芯的开口段。
2: choose the corresponding type of iron core sheath, insert the opening section of the core.
3：为使铁芯推入线圈窗口时绝缘不受损坏，须在铁芯护套和铁芯的硅钢片之间放置点胶纸。
3: In order to keep the core from being damaged when pushing into the coil window, adhesive paper should be placed between the core sheath and the silicon steel sheet of the core.
4：用力平稳地将铁芯推入线圈窗口。
4: push the core into the coil window smoothly.
5：用老虎钳抽出铁芯护套，并用吸尘器清理线圈、绝缘件及芯护套上的非晶碎片。
5: Pull out the iron core sheath with vise, and clean the amorphous debris on the coil, insulator and core sheath with vacuum cleaner.
6：合拢铁芯，合拢过程中必须收紧铁芯；铁芯的搭接头范围一般控制≥6mm，端面不平整度±1mm。
6: The iron core must be tightened in the process of closing; the lap joint range of the iron core is generally controlled to be more than 6 mm, and the unevenness of the end surface is (+ 1 mm).
7：合拢铁心过程中，发现非晶碎片应及时用吸尘器及时清理干净，以防止非晶碎片进入线圈。
7: In the process of closing the core, the amorphous debris should be cleaned up promptly with vacuum cleaner to prevent the amorphous debris from entering the coil.
8：合拢其中一只大铁芯至最外层时，用3M胶带粘住搭接处，防止铁芯片散开。
8: When closing one of the large iron cores to the outermost layer, stick 3M tape to the lap joint to prevent the iron chip from spreading.
9：在非晶铁芯与硅钢片搭扣间放一块5mm橡胶垫，合拢硅钢片搭扣处并用3M胶带粘住搭扣。
9: Place a 5mm rubber pad between amorphous iron core and silicon steel sheet buckle, close the silicon steel sheet buckle and stick the buckle with 3M adhesive tape.
10：整理铁芯搭接端部使之平整，用吸尘器把铁心及工作台面上的非晶碎片吸干净。
10: Finish the lapped end of the iron core to make it smooth. Use a vacuum cleaner to clean the iron core and amorphous debris on the working table.
11：用同样方法合拢其余三只铁芯。
11: close the remaining three cores with the same method.
12：按工艺要求对铁芯搭接处的上端部进行均匀涂玻璃胶，要求玻璃胶厚度为1~2mm。
12: According to the technological requirements, the upper end of the overlap of the iron core is evenly coated with glass glue. The thickness of glass glue is required to be 1-2 mm.
13：在铁芯搭口处的外围用3M胶带绑扎牢固，防止非晶碎片进入线圈。
13: at the periphery of the core opening, 3M tape is used to fasten and prevent amorphous debris from entering the coil.
14：在铁芯的非搭接侧面插入接地铜带，铜带的插入深度≥50mm；插入距铁芯端部外侧约30mm处。
14: Grounded copper strip is inserted into the non-lapped side of the core, the insertion depth of the copper strip is more than 50 mm, and the insertion distance is about 30 mm from the outer side of the core end.
15：将器身装配台托架平稳升起，用吸尘器对器身台面及铁芯搭接扣下端面进行清理非晶碎片，再对铁芯搭接下端面涂玻璃胶。
15: Rise the bracket of the body assembly table smoothly, clean up the amorphous debris on the body table and the bottom face of the iron core lapping buckle with the vacuum cleaner, and then coat the glass glue on the bottom face of the iron core lapping buckle.
