素地の部分より外径を大きくしてプランジヤガイ
ドｇとの摩擦抵抗を少なくしたものであつた。(b) Prior Art Conventionally, the present applicant developed a method for reducing frictional resistance between a plunger and a plunger guide in a solenoid and improving durability.
No. 174815 was devised. As shown in Fig. 4, electron beam welding is performed on the outer periphery of the plunger p continuously in the circumferential direction or at intervals in the circumferential direction to make the outer diameter larger than that of the base material, thereby reducing friction with the plunger guide g. It was something that had less resistance.

う問題点があつた。 However, according to the invention, in electron beam welding of the outer periphery of the plunger p, the bulge (protrusion) m of the welded part
It is difficult to make the height uniform all around the circumference, and therefore processing is required to make the height uniform. Furthermore, since the bulge m of the welded portion cannot be made smooth, there is a problem in that post-processing is required.

題点を解決しようとするものである。(c) Problems to be solved by the invention This invention solves the problems of the prior art as mentioned above, namely the uneven height of the bulge and the bulge when increasing the outer diameter by electron beam welding on the outer periphery of the plunger. This is an attempt to solve the problem that the ascending part is not smooth and requires machining.

ている。(d) Means for solving the problem The plunger guide for a solenoid of the present invention has a plunger movably inserted inside the plunger guide, and the outer circumferential surface is continuous in the circumferential direction or in the circumferential direction. The inner surface of the plunger guide is swollen by being melted by an electron beam to make the inner diameter smaller than that of the base material, thereby reducing frictional resistance with the plunger.

に伝えるプツシユロツドである。 In Fig. 1, 1 is a solenoid using the plunger guide according to the present invention, 2 is a plunger guide made of a tube, 3 is a fixed iron core that is fitted and fixed to one end of the plunger guide, and 4 is a solenoid that is fitted to the other end of the plunger guide. A fixed stopper, 5 a plunger movably inserted into the plunger guide 2, 6 a winding provided around the plunger guide 2, and 7 a yoke surrounding a part of the winding to form a magnetic path. , 8 is a push rod that is inserted into an axial hole of the fixed iron core 3 and transmits the operation of the plunger 5 to, for example, a valve body.

解を行うことによつて得られる。 As shown in detail in FIG. 2, when a part 22 of the outer circumferential surface 21 of the plunger guide 2 is heated and melted with an electron beam, the inner surface 23 of the plunger guide 2 swells and a smooth bulge 24 is formed. Thus, when the plunger 5 moves in the axial direction, the outer surface 51 of the plunger 5 moves along the innermost periphery of the bulge 24 of the plunger guide 2. Since the bulges 24 are formed in an annular shape continuously in the circumferential direction or at predetermined intervals in the circumferential direction, precision finishing can be achieved at a lower cost than in the case of cutting. In addition, the height of the bulge 24 changes depending on the electrical input of the electron beam melting, and if this input is too large, the molten part will penetrate the inner surface 23, so if the input is applied before reaching the inner surface 23, the height of the bulge 24 will be changed. Use the appropriate inputs you previously configured. The state in which the bulges 24 are continuously formed in the circumferential direction can be obtained, for example, by subjecting the outer surface 21 of the plunger guide 2 to a spiral shape 25 by electron beam melting, as shown in FIG.

ゆう動を容易にするという効果がある。(F) Effect The plunger guide according to the present invention has a simple structure in which the outer peripheral surface is melted with an electron beam and the inner surface is bulged, and this bulge can be made uniform and appropriate by applying a preset electric input. It has the effect of making the plunger easy to move due to its smooth height.
