本発明は、ベローの電鋳による製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a bellows by electroforming.
従来よりベローは、伸縮性ある接続具として用
いられるが、電鋳によるベローは、精密な反面、
従来の製造法によるものは、肉厚が不均一で、凸
部と凹部の肉厚が異り、厚い所は伸縮性が劣り、
薄い所は強度が弱くこれは一方向よりの電鋳によ
り作る所にその原因があつた。 Traditionally, bellows have been used as elastic connectors, but electroformed bellows are precise, but
Products made using conventional manufacturing methods have uneven wall thickness, with different wall thicknesses in convex and concave areas, and poor elasticity in thicker areas.
The strength is weak in thinner parts, and this is due to the fact that it is made by electroforming in one direction.
本発明は２段階に分けて電鋳を行い均一化され
た電鋳を行うものである。 The present invention performs electroforming in two stages to achieve uniform electroforming.
以下図面を追つて説明する。 This will be explained below with reference to the drawings.

ある。 First, as shown in FIG. 1A, on a base 1 made of wax or the like, in the case of a nonconductor such as wax that is electroformed using the surrounding electrode 2, it is of course possible to apply a conductive film using a normal silver mirror or the like. Also, it is preferable to perform electroforming while rotating the base 1 in order to achieve uniform electrodeposition.
Then, the part near the positive pole becomes thicker and the part far away becomes thinner. Next, the resulting bellows 3 is taken out by melting the wax, etc., and in a second step, it is electrodeposited from the inside as shown in FIG. Then, since the positive electrode 4 is inside, electrodeposition can be performed by electroforming, thick on the inside and thin on the outside. Depending on the voltage strength and distance of this electrode, it is possible to level it out and perform uniform electrodeposition. Next, FIG. 2 shows a method in which the same effect is produced by the reverse method. First, an electrode 5 is placed on the inside, a base 6 made of flexible rubber or the like is placed on the outside, and electrodeposition is performed by electroforming. Then, a thick electrodeposition occurs on the inside. Place this on a base 6 made of flexible rubber, etc.
In the second step, electrodeposition is performed using the electrode 7 from the outside as shown in FIG. 2B. Then, a bellows 3 having a uniform wall thickness is obtained. It is also possible to obtain a uniform bellows depending on voltage, distance, and other factors.
