この発明は金桐製の薄板をレーザ光で熱処理するときに
その薄板が変形するのを防止する薄板の熱処理方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for heat treating a thin plate made of paulownia wood, which prevents the thin plate from being deformed when the thin plate is heat treated with laser light.
薄板に部分的に表面焼入やチル化などの熱処理を施こす
場合その熱処理を確実かつ迅速に行なえるとともに、他
の部分にあまシ大きな熱影響を及ばずことのない熱源と
してレーザ光が多く用いられている。When performing heat treatment such as surface hardening or chilling on parts of a thin plate, laser light is often used as a heat source that can perform the heat treatment reliably and quickly and without having a large thermal effect on other parts. It is used.

の板厚が３燗以下の場合は、その変形量が急激に大きく
なるということがあった。Conventionally, such heat treatment has been carried out by applying an absorbing material that absorbs laser light to the part of the thin plate a to be heat treated, as shown in Fig. Is it irradiated only from one side? [Was. However, if the Rede light was irradiated from only one side of the thin plate a, the thin plate a would warp significantly around the area irradiated with the laser beam, as shown in Figure 2, so correction processing was required after heat treatment. C,
In the worst case scenario, even after repair, the surface of the board would become wavy and unusable. In particular, thin plate a
When the thickness of the plate is 3 mm or less, the amount of deformation increases rapidly.
この発明はレーデ光によって薄板を熱処理するときに、
この薄板がほとんど変形することがないようにした薄板
の熱処理方法を提供することにある。In this invention, when heat treating a thin plate using Rede light,
It is an object of the present invention to provide a method for heat treating a thin plate in which the thin plate is hardly deformed.
薄板の一方の面あるいは両面をレーザ光で熱処理すると
きに、上記薄板の両面の同一個所を同じ条件のレーデ光
で照射したのち、この薄板を一対のローラで挾持するこ
とによシ、薄板の変形をなくすようにしたものである。When heat treating one or both surfaces of a thin plate with laser light, the thin plate can be heated by irradiating the same location on both sides of the thin plate with laser light under the same conditions and then holding the thin plate between a pair of rollers. This is to eliminate deformation.
以下、この発明の一実施例を第３図と第４図を参照して
説明する。図中１はレーザ装置である。このレーザ装置
Ｊから出力されたレーザ光りは半透鏡２によって第１の
レーデ光Ｌ１ と第２のレーザ光Ｌ２とに分割される。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. 1 in the figure is a laser device. The laser beam output from this laser device J is divided by a semi-transparent mirror 2 into a first laser beam L1 and a second laser beam L2.

レーザ光Ｌ１と第２のレーザ光Ｌ２とは、それぞれ薄板
５の表面と裏面との同一個所を同じ強度で、しかも同じ
スポット径、すなわち同一条件で照射する。The first laser beam L1 is reflected by the first reflecting mirror 3, then focused by the first condensing lens 4, and irradiates the upper surface of the rectangular thin plate 5. After the second laser beam is reflected by the reflecting mirrors 6 and 2 of the edict 3, it is focused by a second condensing lens 8 having the same focal length as the first condensing lens 4, and illuminates the back surface of the thin plate 5. irradiate. The first condensing lens 4 and the second condensing lens 8 have their optical axes coincident with each other, and are spaced apart from each other by the same dimension with respect to the top and back surfaces of the thin plate 5. Therefore, the first laser beam L1 and the second laser beam L2 respectively irradiate the same spot on the front and back surfaces of the thin plate 5 with the same intensity and the same spot diameter, that is, under the same conditions.

る。On the surface of the thin plate 5, an absorbing material 9 made of a substance that easily absorbs Rede light is applied in a band-like manner along the longitudinal direction, for example, at a location where heat treatment is to be performed. Also, thin plate 5
The front and back sides are the first. Second lede light Lt #
After being irradiated by L, ., a pair of rotatably provided rollers 10. It is held and sent by l0Ic.

流出する水冷式となっている。The rollers 10, 10 are hollow and made of a metal with high thermal conductivity, such as copper, and cooling water is supplied to the inside from a supply pipe 11°1 connected to one end surface.
This cooling water is of a water-cooled type and flows out from a discharge pipe 12.12 connected to the other end surface.

っても薄板５の変形が発生しずらくなる。Therefore, in order to partially heat-treat the surface of the thin plate 5,
When the Raded light is output from the Raded device 1, this thin plate 5
The same location on the front and back surfaces of the lens is simultaneously irradiated with the first Rade light L1 and the second Rade light L2 under the same conditions. Therefore, since there is almost no difference in the heat form # applied to the front and back surfaces of the thin plate 5, the deformation of the thin plate 5 becomes extremely small. Moreover, the first part of the thin plate 5. Second radar light L1
The area irradiated by 1L2 is Raded light Ll,r
Immediately after the irradiation with i2, the thin plate 5 is held between the rollers 10, 10, rapidly cooled and straightened, and this also makes it difficult for the thin plate 5 to be deformed.
また、薄板５の表面と裏面とに熱処理を施こしたい場合

同様薄板５を変形させることなく熱処理できる。In addition, if you want to heat-treat the front and back surfaces of the thin plate 5, you can apply the absorbent material 9 to the back side of the thin plate 5 as well, so that you can heat-treat both the front and back surfaces at the same time. Similarly, heat treatment can be performed without deforming the thin plate 5.
なお、薄板５は矩形状だけでなく、円形やリング状のも
のであってもよいことは熱論である。It is a matter of course that the thin plate 5 is not only rectangular, but may also be circular or ring-shaped.

れるので、このことによっても変形が生じすらい。As described above, in this invention, when heat treating one side or both sides of a thin plate with Rede light, the thin plate is heated by irradiating the same location on both sides of the thin plate with Rede light under the same conditions. It was designed to be held between a pair of rollers. therefore,
Since both sides of the thin plate are subjected to almost the same thermal influence, the thin plate can be heat treated with almost no deformation, and since the thin plate is cooled and straightened by being held between a pair of rollers, this also causes deformation. Slightly.
