本発明は試験片に高温で長時間負荷し、材料の強度や変
形を求めるクリープ試験機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a creep tester that applies a load to a test piece at high temperature for a long period of time to determine the strength and deformation of the material.
一般に材料の強さや変形などの機械的性質は、高温では
負荷時間によって左右されるので、高温で長時間連続使

上限をその温度におけるその材料のクリープ限度と称し
、材料の高温特性として装置設計上利用することができ
る。In general, the mechanical properties of materials such as strength and deformation are affected by the loading time at high temperatures, so for parts that are used continuously at high temperatures for long periods of time, the time required for the normal load to break is 1.
A short time test at a high temperature of about 5 to 20 minutes is not appropriate, and it is necessary to perform a creep test at a high temperature. Creep is a phenomenon in which the strain of a material increases over time under a constant load, that is, it continues to deform. A creep curve can be obtained. Although the illustration of this creep curve is omitted, it can be seen from the creep curve that, for example, when the load is kept constant and the temperature falls below a certain limit, creep will stop after a certain time, and the upper limit of the stress will be the creep limit of the material at that temperature. It can be used in equipment design as a material's high-temperature properties.

下部支え台１５の上に位置するように構成されている。In Fig. 2, the lever supported by the fulcrum IK is connected to a lever 2 on the weight side and a lever 3 on the test side, and a weight receiver 4 is placed on the tip of the lever 2 on the weight side of one end of the lever. A weight 5 is placed on the lever 5, and a balance weight 6 is provided at the tip of the test side lever 3 at the other end of the lever. A support 9 to which an upper support rod 8 to which one end of the test piece 7 is screwed is attached is hung from the lever 3 on one side of the test, and a lower support rod 10 is attached to the other end of the test piece 7.
The opposite side of the lower support rod 10 from the test piece 7 is connected to the jack 12 via a cap nut 11. The whole testing machine has a lever placed on an upper support stand 14 fixed to four columns 13, and the test piece 7 is placed on one of the four columns 13.
3, the jack 12 is positioned on a lower support 15 fixed to a column 13.
加熱炉１６はいずれかの支柱１３に取付具を介してと夛

部分を同じ符号で示し、試験片が伸びたときの状態を点
線で表わしである。There are the following problems when performing a shift leap test using the lever type testing machine as described above. FIG. 3 is a schematic diagram showing the relationship between the tensile force on the test piece, and the parts common to those in FIG.

モーメントが減少することになる。すなわち、試験片側
てこ３には元の状態とは異なる力が作用し、この種試験
機は試験片７に常に一定荷重がかからないことになる。In Fig. 3, the distance between the position A of the fulcrum 1 on the lever and the tip B of 2 on the weight side is calculated, the magnitude of the load is W, and the test piece 7 is extended and the 2 is lowered by θ. , then the load point moves from B to B', and if the distance between AB' is L',
The moment when the test piece 7 is lowered by θ with respect to W-L (moment when the lever is in a horizontal state) is L'
It becomes W. Therefore, the moment decreases by W-L (1-cos θ). That is, a force different from the original state is applied to the lever 3 on one side of the test, and a constant load is not always applied to the test piece 7 in this type of testing machine.
このため伸びの大きい試験片では第２図に示したギヤ一
式ジヤツキ１２によシ試験片７を引張シ、重錘側てこ２
と試験片側てこ３からなるレバーを床面に対して水平に
保っておかなければならず、試験機の操作を煩雑にする
ものであった。For this reason, in the case of a test piece with a large elongation, the test piece 7 is pulled by the gear set jack 12 shown in FIG.
The lever consisting of the lever 3 on one side of the test had to be kept horizontal to the floor surface, which made the operation of the testing machine complicated.
本発明の目的は上述の点に鑑みてなされたものであシ、
その目的はてこ式の引張クリープ試験機において試験片
の伸びによって引張力が減少しないよう、レバーの移動
Ｋかかわらず一定荷重を常に定位置でかけることを可能
とするクリープ試験機を提供することにある。The object of the present invention has been made in view of the above points, and
The purpose is to provide a lever-type tensile creep tester that can always apply a constant load at a fixed position regardless of the movement of the lever so that the tensile force does not decrease due to elongation of the test piece. .
本発明はレバーを重錘側てこと試験片側てことがいずれ

それぞれ支店から一定の曲率をもった円弧をなしておシ

もシで試験片に引張力を与えるようＫしたものである。In the present invention, the lever on the weight side and the lever on the test side both have a shape that spreads out in a fan shape from the branch, and the tip of each of these levers forms an arc with a certain curvature from the branch, and the end face is U-shaped. A shaped groove was provided, and on the lever on the weight side, a wire fitted along this groove was hung longer than the arc surface, a weight holder was placed on the tip of the wire, a weight was placed on the tip, and a weight was placed on the lever for testing. Similarly, for the lever on one side, a wire fitted along the U-shaped groove is hung longer than the arc surface, and an upper support rod is attached to the tip of the wire, and one end of the test piece is screwed to this. The other end was screwed to the lower support rod, and a tension force was applied to the test piece with a weight suspended from the curved part of the vertical lever by a wire.
本発明は前述のごとくレバーの重錘側てこと試験片側て

作用し、一方試験片側てこに設けたワイヤーも、てこ端
面のＵ字状溝に追従して動くので、試験片には常に一定
の引張力が与えられるように作用する。As mentioned above, the tip of the lever on the weight side of the lever and the test side of the lever are arcuate 9, and both tips are made by extending and hanging down a wire fitted into a U-shaped groove formed on the end surface. In addition, because the load was applied to the test piece by lowering the weight and the test piece, even if the test piece stretched and the weight side lever descended, it would not fit into the U-shaped groove on the end of the lever. Simply by removing the wire from the groove, the weight hanging from the tip of the wire always moves perpendicular to the floor surface, acting to apply a constant load to the test piece without changing the load point. On the other hand, the wire attached to the lever on one side of the test also moves following the U-shaped groove on the end face of the lever, so that a constant tensile force is always applied to the test piece.
以下本発明を実施例に基づき説明する。 The present invention will be explained below based on examples.

きる。The biggest difference between Fig. 1 and Fig. 2 is that in Fig. 1, the lever 2a on the lever weight side is framed around the fulcrum 1 and has a fan-like shape, and the side surface of the tip is shaped like a fan. It is a circular arc surface with a constant curvature from the test side lever 3a.
Similarly, it has a fan shape with the fulcrum 1 at its center, and the side surface of the tip forms an arcuate surface. A U-shaped groove (not shown) is formed on each of these arcuate surfaces to provide a lever and a lever.
On the a side, the wire 17 fixed at position A is fitted along this U-shaped groove and extended to the bottom of the arcuate surface and hangs down.A weight receiver 4a is attached to the tip of the wire 17, and the weight receiver 4
Place the required weight 5 on top of a.0 At this time, the tip of the weight side lever 2a will have a large moment from the fulcrum 1, so the weight 5 will be tested. It is lighter than the specified load of 7K per piece.

One end of the test piece 7 is screwed to the upper support rod 8, the other end is screwed to the lower support rod 10, and the lower support rod 10 is connected to the jack 12 via the cap nut 11 as shown in FIG. In addition, to install the balance weight 19 in the no-load state, insert the balance weight 19 into two weight supports 20 attached to one side of the test surface and on both sides of the fan-shaped surface of 38 so that it can move freely. This is done by tightening the fixing screw 21 at a balanced position.

K moves downward, so as a guide, an angle scale 22 is provided near the fulcrum 1 on the lever 2a, and the pointer 23
When attached to the upper support stand 14, A of the weight side lever 2a
By pulling one side of the test point using the jack 12 and aligning the pointer 23 with the zero point of the angle scale 22 before the position becomes horizontal to the floor surface, the lever can be brought into the same state as at the start of the test.

The test procedure is exactly the same as that shown in Fig. 2, in that the heating furnace 16 is installed on one of the supports 13 via a fixture, and the test procedure is also the same as that shown in Fig. 2. Since this is the same as in the case, the explanation thereof will be omitted. Also, in FIG. 1, the device for measuring the elongation of the test piece 7 is not shown. Connect a weight on one end and a test piece on the other end of a wire suspended along the arcuate surface of the lever. This makes it possible to hold a predetermined load without having to consider the horizontal position each time.

る。In conventional lever-type creep testing machines, when the test piece stretches and the lever on the weight side of the lever goes down, the moment decreases compared to when the lever is in a horizontal position, and a constant load is not applied to the test piece. According to the present invention, as explained above, the lever on the weight side and the lever on the test side are both placed on a fulcrum. The side surfaces of the tips of these levers are circular arc surfaces with a constant curvature from the fulcrum, and a U-shaped groove is provided on that surface, and a wire is suspended along the inside of this groove. Since the creep test was performed by connecting a weight to the tip of the wire on one end and attaching the test piece to the other end, when the test piece stretches and the lever on the weight side descends, the wire comes off the arc surface. , the weight will continue to fall in a direction perpendicular to the floor surface, allowing it to continue in the same state as when the lever is held horizontally with conventional equipment, resulting in a decrease in moment without changing the load point. A similar phenomenon occurs on the lever on one side of the test, and a constant tensile force is always applied to the test piece, causing the test piece to stretch on its central axis. The tensile force applied to the piece K remains unchanged throughout the test period and the test can be completed.
以上のことから従来の試験機では、レバーの水平状態を

を有するものである。For the above reasons, with conventional testing machines, it was necessary to check frequently to maintain the horizontal state of the lever, but with the testing machine of the present invention, reliability can be ensured by using an angle check pointer installed near the fulcrum. Therefore, the testing machine of the present invention has the effect of greatly improving test accuracy and handling.
