【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、フラッシュパネルに排水孔等を穿孔する穿
孔装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a punching device for punching a drainage hole or the like in a flash panel.
従来、キッチンカウンタ等において、第５図（Ａ）に示
すように、上板５０と下板５１との間を中空としたフラ
ッシュパネル５２が用いられている。Conventionally, in a kitchen counter or the like, as shown in FIG. 5 (A), a flash panel 52 in which a space between an upper plate 50 and a lower plate 51 is hollow is used.
このようなフラッシュパネル５２に例えば直径１３０mm
程度の排水孔を開ける場合、ホールソーを用いることが
考えられる。Such a flash panel 52 has a diameter of 130 mm, for example.
A hole saw may be used to open a drainage hole to some extent.
しかし、第５図（Ｂ）のようにホールソー５３で穿孔す

上に落ち、ホールソー５３がその上に乗る。そのため、
端材５０ａがホールソー５３とともに回転し、下板５１
を穿孔できないという問題点がある。However, when punching with the hole saw 53 as shown in FIG. 5 (B), after the punching of the upper plate 50, the scrap material 51 a is cut off from the lower plate 51.
It falls and the hole saw 53 rides on it. for that reason,
The scrap 50a rotates together with the hole saw 53, and the lower plate 51
There is a problem that it cannot be drilled.
この考案の目的は、フラッシュパネルに上下板を貫通し
た孔を良好に開けることができる穿孔装置を提供するこ
とである。An object of the present invention is to provide a punching device capable of satisfactorily forming a hole penetrating the upper and lower plates in a flash panel.

の後端に接続している。[Means for Solving the Problem] The punching device of the present invention comprises a hole saw, a rotation driving device, a suction pad, a pipe, and a vacuum generator. The hole saw is provided with a hollow shaft portion communicating with the inside of the cylindrical portion on the rear end surface of which the cutting teeth are formed along the peripheral edge of the tip opening of the cylindrical portion. The rotation driving device is connected to the shaft portion to rotate the hole saw.
The suction pad is arranged in the cylindrical portion and sucks the material to be perforated with a negative pressure. The pipe is inserted in the shaft portion in a loosely fitted state and has a suction pad connected to the tip thereof. The vacuum generator is connected to the rear end of the pipe.
この考案の構成によると、フラッシュパネルの上板を穿
孔したときに生じた端材がホールソー内の吸着パッドで
吸着され、下板上に落下しない。そのため、端材が邪魔
とならずに下板をホールソーで穿孔することができる。According to the configuration of this invention, the end material generated when the upper plate of the flash panel is punched is adsorbed by the adsorption pad in the hole saw and does not fall on the lower plate. Therefore, the lower plate can be pierced by the hole saw without the end material interfering.

回転駆動装置７を構成している。An embodiment of the present invention will be described with reference to FIGS. The shaft portion 1a of the hole saw 1 is rotatably supported by the bearing 2, and the sprocket 3 is fixed to the upper end of the shaft portion 1a. The sprocket 3 is connected to the sprocket 5 provided on the output shaft of the motor 4 by a belt 6, and the motor 4, the sprockets 3, 5, and the belt 6 constitute a rotary drive device 7 for the hole saw 1.

着パッド９およびパイプ８は回転しない。The shaft portion 1a of the hole saw 1 is a hollow shaft, and the pipe 8 is loosely fitted therein. The lower end of the pipe 8 is located inside the hole saw 1, and the suction pad 9 is connected thereto. The upper end of the pipe 8 is connected to a vacuum generator 10 such as a vacuum pump. The suction pad 9 and the pipe 8 do not rotate.

駆動される。The motor 4, the bearings 2, the vacuum generator 10 and the like are installed on the same lift (not shown), and when punching, the lift drive device as a whole moves up and down together with the lift.
第３図に示すように、ホールソー１は筒部１ｂの下端に
鋸歯状の切歯１ｃを有する。As shown in FIG. 3, the hole saw 1 has serrated cutting teeth 1c at the lower end of the cylindrical portion 1b.

５０ａを放して穿孔が完了する。５１ａは下板５１の端
材である。このように、フラッシュパネル５２に上下板
５０，５１を貫通して良好に穿孔することができる。According to this configuration, when the upper plate 50 of the flash panel 52 is punched by the hole saw 1 as shown in FIG. 4 (A), suction of the suction pad 9 is started and the end material 50a is held by the suction pad 9. Therefore, it is possible to reliably prevent the scrap 50a from falling onto the lower plate 51. That is, the pipe 8
Is inserted into the shaft portion 1a in a loosely fitted state, the suction pad 9 does not rotate even if the hole saw 1 rotates, and the upper plate 50 is cut before the end material 50a is cut out from the upper plate 50. This is because the suction pad 9 can suck the portion to be the scrap 50a. As a result, the scrap 50
The lower plate 51 can be punched with the hole saw 1 as shown in FIG. At the same time when the hole is made in the lower plate 51, the suction of the suction pad 9 is turned off, and the end material 50a is released to complete the punching. 51a is a scrap of the lower plate 51. Thus, the flash panel 52 can be satisfactorily perforated by penetrating the upper and lower plates 50, 51.

良好に穿孔することができるという効果がある。In the punching device of this invention, since the pipe is inserted into the shaft portion in a loosely fitted state, the suction pad does not rotate even if the hole saw rotates. Therefore, before the material to be perforated is cut out from the veneer plate or the like by the hole saw, the portion to be the material to be perforated such as the veneer plate can be sucked by the suction pad. As a result, the material to be punched that has been cut out and is about to fall at the same time can be reliably held, so that there is an effect that the lower plate can be satisfactorily pierced by the hole saw without the end material interfering.
