本発明は、エンジンバルブ等に使用されるきのこ形弁の
シート部の加工方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of processing a seat portion of a mushroom-shaped valve used in an engine valve or the like.
従来、エンジンバルブを製造する際には、第２図に示す
ように、弁傘部２を鍛造成形後、シート部３の盛金用溝
４を旋削加工し、その後該溝４に盛金していた。１は弁
軸部である。Conventionally, when manufacturing engine valves, as shown in FIG. 2, after the valve head part 2 is forged and formed, the groove 4 for filling in the seat part 3 is lathed, and then the groove 4 is filled with metal. was. 1 is a valve stem portion.
即ち、従来エンジンバルブを製造するには、第２図に示
すように、
（１）エンジンバルブ素材を鍛造し成形する。（第１図

（２）シート部３を旋削して盛金用溝４を形成する。That is, in order to manufacture conventional engine valves, as shown in FIG. 2, (1) an engine valve material is forged and formed. ((1) in FIG. 1) (2) Lathe the seat portion 3 to form the groove 4 for filling.
（第１図の（２））
（３）該溝４に盛金５を行う。（第１図の（３））〔発
明が解決しようとする問題点〕
しかしながら、エンジンバルブの材質は難削な耐熱鋼で
あるため、従来のように盛金前に溝４の旋削加工を行う
方法では加工工具の消耗が激しく作業能率が低下する。((2) in Fig. 1) (3) Fill the groove 4 with metal 5. ((3) in Figure 1) [Problem to be solved by the invention] However, since the material of the engine valve is heat-resistant steel that is difficult to machine, the groove 4 is turned by turning before filling as in the conventional method. This method causes severe wear on the processing tools and reduces work efficiency.
また、切削屑は形状不安定で処理が困難なため、これの
処理に人手を要することから作業の自動化が阻害されて
いる。Furthermore, since cutting waste has an unstable shape and is difficult to dispose of, it requires manpower to dispose of it, which hinders the automation of work.
本発明は上記に鑑みなされたもので、旋削加工の工数を
低減す、ることにより製造工数が低減されたきのこ形弁
の製造方法を提供することを目的とする。The present invention has been made in view of the above, and an object of the present invention is to provide a method for manufacturing a mushroom-shaped valve in which the number of manufacturing steps is reduced by reducing the number of turning steps.
〔問題点を解決するための手段、作用〕一般にエンジン
バルブの傘部は鍛造成形されたものであり、また難削材
でもあるので旋削加工が困難である。本発明においては
、弁傘部の鍛造時に盛金用溝部の精密鍛造を同時に行な
うことＫより、旋削工程を省略するようにしたことを特
徴とする。[Means and actions for solving the problem] In general, the cap portion of an engine valve is forged and made of a difficult-to-cut material, so turning it is difficult. The present invention is characterized in that the turning process is omitted since precision forging of the fill groove is performed simultaneously when the valve head is forged.
以下第１図を参照して本発明の１実施例につき説明する
と、図は本発明方法をエンジンバルブに適用した場合の
工程を示し、図において１は弁軸部、２は弁傘部、３は
シート部である。Below, one embodiment of the present invention will be described with reference to FIG. 1. The figure shows the process when the method of the present invention is applied to an engine valve. is the seat part.
次に本発明に係る製造方法につき説明する。Next, the manufacturing method according to the present invention will be explained.
（１）エンジンバルブを精密鍛造により成形する。(1) The engine valve is formed by precision forging.
この場合、シート部３の盛金用溝４も同時に成形する。In this case, the metal filling groove 4 of the seat portion 3 is also formed at the same time.
（第１図（１））
（２）次に該溝４にステライト等からなる盛金材５を肉
盛りする。（第１図（２））
（３）その後、外形を研削加工してパルプを仕上げる。(FIG. 1 (1)) (2) Next, the groove 4 is filled with a filler material 5 made of stellite or the like. (Figure 1 (2)) (3) After that, the outer shape is ground to finish the pulp.
上記方法によれば、従来の方法のような盛金用溝４の旋
削加工が不要となり、パルプの加工工数が低減される。According to the above method, the lathing groove 4 does not need to be turned as required in the conventional method, and the number of man-hours required for pulp processing is reduced.
以上のように本発明方法によれば、加工困難な溝部の切
削工程を省略することができるので、弁の工数の低減、
切粉処理の不要等による製造コストの低減が可能となる
。As described above, according to the method of the present invention, it is possible to omit the process of cutting grooves that are difficult to machine, thereby reducing the number of man-hours for manufacturing the valve.
Manufacturing costs can be reduced by eliminating the need for processing chips.
