本発明は段違い構造をなすバイメタルに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bimetal having a stepped structure.
周知のように温度調節や接点開閉用として用い

合面に対して直角で、且つ燃膨張係数が低い例え
ば金属片Ａ側に向けた単１方向のみに作動してい
る。 As is well known, bimetals used for temperature control and contact opening/closing are made by bonding two types of metal pieces with different thermal expansion coefficients side to side, and as the temperature rises, the metal piece with a higher thermal expansion coefficient It takes advantage of the metal's ability to bend to one side, which has a high coefficient of thermal expansion and a low elongation. In other words, as shown in Fig. 1, a normal bimetal operates only in one direction, which is perpendicular to the joint surface of two metal pieces A and B, and toward metal piece A, which has a low coefficient of fuel expansion. are doing.

が必要となつている。 For example, in color television picture tubes, bimetals are used as members to elastically support the shadow mask against the glass container in order to compensate for the displacement of the shadow mask due to thermal expansion. Since displacement is a combination of movements in two mutually orthogonal directions, the bimetal used in this case cannot operate in a single direction, but is required to operate in two mutually orthogonal directions. in this way,
As the use of bimetals has expanded in recent years, there has been a need for bimetals with not only unidirectional operation but also bidirectional operation.
本発明は前記事情に鑑みてなされたもので、２
方向作動を同時に行なえるバイメタルを提供する
ものである。 The present invention has been made in view of the above circumstances, and includes:
The present invention provides a bimetal that can perform directional operation at the same time.

造のバイメタルが得られる。 FIG. 2 shows an embodiment of the bimetal of the present invention. In the figure, 1 is one metal piece forming a strip, and 2 is the other metal piece forming the band. The metal piece 1 has a high coefficient of thermal expansion, and the other metal piece 2 has a low coefficient of thermal expansion. These metal pieces 1 and 2 are arranged in parallel, with one edge along the longitudinal direction of the side surface (top surface in the figure) 1a of one metal piece 1 and the side surface (bottom surface in the figure) of the other metal piece 2 opposing this. ) The other side edges along the longitudinal direction of the metal pieces 1 and 2 are overlapped along the longitudinal direction of the metal pieces 1 and 2, and the side edges of each side surface 1a and 2a that are overlapped with each other are seam welded or filleted. They are joined by welding. For this reason, the metal pieces 1 and 2 have side surfaces 1 facing each other along the longitudinal direction.
Parts of a and 2a are polymerized and joined to obtain a bimetal with a stepped structure.

When used with the metal piece 2 on the lower right side and the other metal piece 2 having a low coefficient of thermal expansion on the upper left side, the bimetal will thermally deform as the temperature rises and try to operate in two directions. First, since parts of the side surfaces 1a and 2a of the metal pieces 1 and 2 are overlapped with each other, this overlapping portion causes the thickness direction of the metal pieces 1 and 2 (direction perpendicular to the side surfaces 1a and 2a: up and down in the figure). direction) movement occurs. That is, one metal piece 1 on the high expansion side has a large elongation in the thickness direction, and the other metal piece 2 on the low expansion side has a small elongation in the thickness direction. For this reason, one metal piece 1 with a large elongation acts to bend toward the other metal piece 2 with a small elongation (upwards in the thickness direction), so that the metal pieces 1 and 2 as a whole act in the thickness direction. The upward movement is Y. Also, metal pieces 1 and 2
By overlapping a part of the side surfaces 1a and 2a along the longitudinal direction of the metal pieces, the metal pieces 1 and 2 are aligned in parallel and joined, that is, aligned in the width direction and joined. Width direction of 1 and 2 (direction parallel to side surfaces 1a and 2a: horizontal direction in the drawing)
movement occurs. That is, one metal piece 1 on the high expansion side has a large elongation in the width direction, and the other metal piece 2 on the low expansion side has a small elongation in the width direction. For this reason, one metal piece 1, which has a large elongation, tries to bend toward the other metal piece 2, which has a small elongation (toward the left side in the width direction), so the metal pieces 1, 2
The overall movement is a leftward movement X in the width direction. As for the bimetal as a whole, the leftward movement X in the thickness direction of the metal pieces 1 and 2 is combined to create a movement Z diagonally upward to the left in the figure, resulting in metal pieces 1 and 2.
2 operates to turn diagonally upward to the left.
In this way, the bimetal is thermally deformed so that the metal piece 1,
The bimetallic actuator simultaneously operates in two directions, the thickness direction and the width direction, and performs a bimetallic operation in which these two directions are combined.

て、このように高熱膨張係数をもつた金属片１と
低熱膨張係数をもつた金属片２との組合せ方を
種々変えることにより、種々の異なる二方向の動
きをもつて作動するバイメタルが得られる。 FIG. 3 shows, as another example, a bimetal polymerized by placing a metal piece 1 with a high coefficient of thermal expansion on the lower left side and a metal piece 2 with a low coefficient of thermal expansion on the upper right side, and polymerizing them in steps. , the upward movement y and the rightward movement x' of this bimetal are combined to perform an operation with a movement z 2 diagonally upward to the right.
Furthermore, Fig. 4 shows a bimetal with a stepped structure in which metal piece 1 is placed on the upper left side and metal piece 2 is placed on the lower right side, and in this bimetal, the rightward movement x' and the downward movement y' are combined. movement diagonally downward to the rightz 3
The bimetal shown in FIG. 5 performs an operation with a diagonally downward leftward movement z4 , which is a combination of the leftward movement x and the downward movement y'. Therefore, by changing the combination of the metal piece 1 with a high coefficient of thermal expansion and the metal piece 2 with a low coefficient of thermal expansion in various ways, it is possible to obtain bimetals that operate with movements in various different directions. It will be done.

It is also possible to support objects with complex movements in two directions, such as a shadow mask in a picture tube. In addition, each width dimension of metal pieces 1 and 2,
By changing the size of the overlapping width dimension, the direction of the combined actuation can be changed. Also,
Materials for the metal pieces 1 and 2 include amber (36% Ni-Fe) for low expansion, and 18-8 stainless steel for high expansion.
