本発明は、筒状フレームの内側に永久磁石界磁をとり
つけた小形直流機のフレームの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a frame for a small direct current machine in which a permanent magnet field is attached to the inside of a cylindrical frame.
この種の直流機においては、第１図に示すように、筒
状フレーム１の内面数個所に取付座２を設けて、永久磁
石界磁３を取りつけてあり、フレーム１と永久磁石界磁
３との間の磁気抵抗を小さくするため、取付座２の底面
４を機械切削により平面に仕上げるようにしている。In this type of DC machine, as shown in FIG. In order to reduce the magnetic resistance between the mounting seat 2 and the mounting seat 2, the bottom surface 4 of the mounting seat 2 is finished into a flat surface by machine cutting.
このため、フレームの加工が面倒で、工数が大きくなる
欠点があつた。 本発明はこのような点を改良するとと
もに塑性加工のさい生ずるバリを積極的にフレームのノ
ックに適用しようとする方法てある。For this reason, processing of the frame was troublesome and required a large number of man-hours. The present invention is a method for improving these points and actively applying burrs generated during plastic working to knocks on frames.
図に示す実施例において、１１は取付座２と同一形状
のしごき刃１２をフレームの取付座と同じ位置にそなえ
たしごきポンチ、１３は外形受け治具てその内径を筒状
フレーム１の外形と同一寸法にしてある。In the embodiment shown in the figure, 11 is an ironing punch with an ironing blade 12 having the same shape as the mounting seat 2 at the same position as the mounting seat of the frame; They are the same size.
１４は端面受け治具でたとえば筒状に形成し内径をフレ
ームのノック外径と同一に設定している。Reference numeral 14 denotes an end face receiving jig, which is formed into a cylindrical shape, for example, and whose inner diameter is set to be the same as the knock outer diameter of the frame.
１５はフレーム素材、１６はしこきポンチ１１を矢印の
方向にフレーム素材１５に圧入し塑性加工したときに生
起したバリである。15 is a frame material, and 16 is a burr generated when the punch 11 is press-fitted into the frame material 15 in the direction of the arrow and plastic working is performed.
外形受け治具１３を端面受け治具１４に重ね、外形受
け治具１３内にフレーム素材１５を挿入する。フレーム
素材１５の上端からしごきポンチ１１を矢印の方向に圧
入すると、フレーム素材１５は外形受け治具１３で外形
を制御され、しごき刃１２によつてこの部分が下方に流
され塑性変形により取付座２が加工される。 しごきに
より下方に流れ端面に生じたバリ１６は、そのＡ、Ｂ個
所て最大となる波状形を呈する。The outer shape receiving jig 13 is stacked on the end surface receiving jig 14, and the frame material 15 is inserted into the outer shape receiving jig 13. When the ironing punch 11 is press-fitted from the upper end of the frame material 15 in the direction of the arrow, the outer shape of the frame material 15 is controlled by the outer shape receiving jig 13, and this part is flowed downward by the ironing blade 12 and plastic deformation occurs on the mounting seat. 2 is processed. The burr 16 that flows downward and is generated on the end surface due to ironing takes on a wavy shape that is maximum at points A and B.
この生成したバリ１６をフレーム１の片側のノックとし
て使用しており、改めてノックをフレーム端面から切削
加工によつて形成する必要がない。The generated burr 16 is used as a knock on one side of the frame 1, and there is no need to form another knock from the end face of the frame by cutting.
なお、端面受け治具１４の内径は必ずしもフレームのノ
ック外径と同一にする必要はなく、ノック外形より若干
大きく設けて塑性加工後にバリの外周をノック外径まで
切削するようにしてもよい。なお、フレーム素材はたと
えば鋼管（商品名ＳＴＫＭ−１３Ａ−Ｃ）であり、しご
きポンチ１１を固定しフレーム素材１５に圧力を加えて
引き抜くようにして塑性加工してもよい。Note that the inner diameter of the end face receiving jig 14 does not necessarily have to be the same as the knock outer diameter of the frame, and may be set slightly larger than the knock outer diameter so that the outer periphery of the burr is cut to the knock outer diameter after plastic working. The frame material is, for example, a steel pipe (product name STKM-13A-C), and may be plastically worked by fixing the ironing punch 11 and applying pressure to the frame material 15 to pull it out.
このように、本発明はフレーム内側の取付座と同形のし
ごき刃をそなえたしごきポンチをフレーム素材の軸方向
に圧入して塑性加工により、すべての取付座３を一度（
あるいは取付座ことに複数度）に加工するようにしてあ
るから、永久磁石界磁のフレームへの取付位置が正確で
、フレームとの密着性も良好となり、しかもフレームの
一端に塑性加工で発生したバリを積極的にノックとして
使え、フレーム材料の節減と、フレーム加工および界磁
取付作業の生産性を著るしく向上させることができる。In this way, the present invention press-fits an ironing punch equipped with an ironing blade of the same shape as the mounting seats inside the frame in the axial direction of the frame material and performs plastic processing to remove all the mounting seats 3 at once (
In addition, since the mounting seat is machined multiple times, the mounting position of the permanent magnet field to the frame is accurate, and the adhesion to the frame is also good. The burr can be actively used as a knock, saving frame materials and significantly improving the productivity of frame processing and field installation work.
