〔産業上の利用分野〕
本発明はりニヤパルスモータの鉄心磁極歯形成方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for forming iron core magnetic pole teeth for a linear pulse motor.
従来のこの種の鉄心磁極歯形成方法の一つは、第３図に
示すように、磁性体薄板をカッターによって溝９−ａを
形成し、その溝と溝との間の部分を磁極歯９−ｂとして
利用していた。また他の方法は、第４図に示すように写
真製版技術を応用し、エツチングによって溝１０−ａを
形成させる方法も採られていた。One of the conventional methods of forming iron core magnetic pole teeth of this type is to form grooves 9-a in a magnetic thin plate using a cutter, and to form the magnetic pole teeth 9 in the portion between the grooves, as shown in FIG. -b was used. Another method, as shown in FIG. 4, is to form the grooves 10-a by etching using photolithography.
上述した従来の第１の鉄心磁極歯形成方法は、カッター
などの機械加工によって多数の溝を掘るため、カッター
の摩耗による溝巾の変化から来る磁極歯中の変化カッタ
ーの耐久性、加工時間等の問題がある。In the above-mentioned first conventional iron core magnetic pole tooth forming method, a large number of grooves are dug by machining with a cutter, etc., so changes in the magnetic pole teeth due to changes in groove width due to cutter wear, etc. cutter durability, machining time, etc. There is a problem.
また、第２の方法では、写真製版によるため、寸法精度
は問題ないものの、コッテング加工前後のマスキングや
露光、エツチング等の工程が多く、量産性を欠く等の問
題がある。The second method uses photolithography, so although there is no problem with dimensional accuracy, there are many steps such as masking, exposure, and etching before and after the cotting process, and there are problems such as a lack of mass productivity.
本発明の鉄心磁極歯形成方法は、磁極体薄板を塑性加工
し、磁極歯列の両端に磁極歯の磁気回路的に無関係な半
凹（金型は凸部）を設けた形状を特徴とする。The iron core magnetic pole tooth forming method of the present invention is characterized by plastically working the magnetic pole body thin plate and providing a shape in which semi-concave portions (the mold is a convex portion) that are unrelated to the magnetic circuit of the magnetic pole teeth are provided at both ends of the magnetic pole tooth row. .
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明による磁性体薄板４の塑性加工によって
形成している断面図である。下型１（上。！： ４４、
磁極歯や形成す、凹お７−７れ、また上型２（下型）に
は磁極歯を押し出す凸部２−ａを有している。FIG. 1 is a sectional view of a magnetic thin plate 4 formed by plastic working according to the present invention. Lower mold 1 (upper.!: 44,
The magnetic pole teeth are formed with concave holes 7-7, and the upper mold 2 (lower mold) has a convex portion 2-a for pushing out the magnetic pole teeth.
両端部には、下型１（上型）には半凸部８−ｂ１上型２
（下型）には半凸部３−ｂを設は下型（上型）の凸部５
−ｃ及び上型凸部２−ａの破損を防ぐ。At both ends, the lower mold 1 (upper mold) has a semi-convex portion 8-b1 and the upper mold 2
The (lower mold) has a semi-convex portion 3-b, and the lower mold (upper mold) has a convex portion 5.
-c and upper mold convex portion 2-a from being damaged.
第２図ａは磁性体薄板の斜視図である。磁極歯７−ａは
半凹部６−ｂにより材料の流れが規制されるため均一な
磁極歯を得ることができる。FIG. 2a is a perspective view of the magnetic thin plate. Since the flow of material in the magnetic pole teeth 7-a is regulated by the semi-concave portion 6-b, uniform magnetic pole teeth can be obtained.
以上説明したように、本発明は、塑性加工によって形成

Furthermore, damage to the convex portions of the upper and lower tooth molds of the end mold can be prevented. Furthermore, the durability of the mold can be increased and more uniform iron core magnetic pole teeth can be obtained.
