本発明はプレスブレーキに使用する楔装置に係
り、さらに詳細には、プレスブレーキに使用する
金形における底部の高さを調節するための楔装置
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wedge device used in a press brake, and more particularly to a wedge device for adjusting the height of the bottom of a mold used in a press brake.
初めに第１図・第２図・第３図によつて本発明
のなされた背景について説明する。 First, the background of the present invention will be explained with reference to FIGS. 1, 2, and 3.
第１図はプレスブレーキ１を示したもので、機
台３に固定した下型５上に被加工材７を配置し、
機台３の両側に設けたコラム９，９の上端に設け
た流体圧シリンダ１１，１１に駆動され、前記コ
ラム９，９に案内されて下型５に接近・離反する
ラム１３の下面に設けた上型１５によつて、被加
工材７を折曲げる方式のプレスブレーキ１が例示
してある。 FIG. 1 shows a press brake 1, in which a workpiece 7 is placed on a lower die 5 fixed to a machine stand 3,
It is driven by hydraulic cylinders 11, 11 provided at the upper ends of columns 9, 9 provided on both sides of the machine base 3, and is provided on the lower surface of a ram 13 that approaches and moves away from the lower die 5 while being guided by the columns 9, 9. A press brake 1 is illustrated in which a workpiece 7 is bent by an upper mold 15.
上記したプレスブレーキ１の下型５は、第３図
に示したように下型７の溝部の両肩１７，１７と
下型７の溝部の中央に設けた底型１９の上面との
３点に被加工材７の下面を当接して折曲げること
ができるように工夫してある。 The lower mold 5 of the press brake 1 described above has three points, as shown in FIG. It is devised so that the lower surface of the workpiece 7 can be brought into contact with and bent.
すなわち底型１９は下型５の溝の中で上下方向
の位置、言い換えれば下型５の両肩１７からの距
離を微調整可能に設けてあるのである。 That is, the bottom mold 19 is provided in the groove of the lower mold 5 so that its vertical position, in other words, the distance from both shoulders 17 of the lower mold 5 can be finely adjusted.
本発明は上記した底型１９の高さ位置を微調整
する楔装置２１を実施例として説明する。 The present invention will be described using a wedge device 21 for finely adjusting the height position of the bottom mold 19 as an embodiment.
第２図に示したように従来の楔装置２１′は、
鋸歯形の板状の固定楔部材２３と、同寸同形の鋸
歯形を備えた可動楔部材２５とを対向して設け、
両楔部材の傾斜部を摺動移動して、平行な鋸背間
の距離を変更するものであつた。 As shown in FIG. 2, the conventional wedge device 21' is
A sawtooth plate-shaped fixed wedge member 23 and a sawtooth-shaped movable wedge member 25 of the same size and shape are provided facing each other,
The distance between the parallel saw spines was changed by sliding the sloped portions of both wedge members.
したがつて第２図に示したように鋸背間の距離
が大きくなるように変更すると、空間部２７を隔
てて他の楔部材と対向する部分が大きくなり、極
端な場合には傾斜部の99％が空間部２７に接し、
わずかに１％で対向する楔部材に支承されるよう
なことになる。 Therefore, if the distance between the saw blades is changed to be larger as shown in FIG. 2, the portion facing the other wedge members across the space 27 will become larger, and in extreme cases, the sloped portion may become larger. 99% is in contact with the space 27,
It will be supported by the opposing wedge member by only 1%.
上記した底型１９は上型１５により被加工材７
を介して強く下圧されているから、前記した可動
楔部材２５の空間部２７に面する部分が下向きに
撓むことになり、折曲げ製品の曲げ精度が著るし
く低下する不都合があつたのである。 The above-mentioned bottom die 19 is moved to the workpiece 7 by the upper die 15.
As a result, the portion of the movable wedge member 25 facing the space 27 is bent downward, resulting in a disadvantage that the bending accuracy of the folded product is significantly reduced. It is.
本発明の楔装置２１は従来装置の上記不都合を
解消する目的でなされたもので、第４図・第５
図・第６図にもとづいて実施例を詳細に説明す
る。 The wedge device 21 of the present invention was made for the purpose of solving the above-mentioned disadvantages of the conventional device, and is shown in FIGS. 4 and 5.
The embodiment will be described in detail based on FIG.
本実施例の固定楔部材２３と可動楔部材２５
は、いづれも平角材２９，３１を中央にしたサン
ドイツチ構造に設けてあり、平角材３１を平角材
２９に比較して高さ方向の大きな材料にしてあ
る。 Fixed wedge member 23 and movable wedge member 25 of this embodiment
Both are provided in a sanderch structure with rectangular members 29 and 31 in the center, and the rectangular member 31 is made larger than the rectangular member 29 in the height direction.
また上記した平角材３１と２９とを中央にした
サンドイツチ構造の楔装置２１は、前記３つの構
成物をボルトなどの適宜な緊締具３３で１体化し
てある。 Further, the wedge device 21 having a sandwich structure in which the above-described rectangular members 31 and 29 are in the center has the three components described above integrated with a suitable tightening member 33 such as a bolt.
以上詳記した本実施例装置は、可動楔部材２５
も固定楔部材２３も平角材３１，２９を中央にし
たサンドイツチ構造とし、更に可動楔部材２５の
平角材３１の方を撓み抵抗の強い高さ方向に寸法

７に当面する傾斜部が90％を越えることがあつて
も可動楔部材２５が撓むことがないのである。 The device of this embodiment described in detail above has a movable wedge member 25
The fixed wedge member 23 also has a sandwich structure with rectangular members 31 and 29 in the center, and the rectangular member 31 of the movable wedge member 25 is made of a material with larger dimensions in the height direction that has stronger deflection resistance. Space part 2
Even if the inclined portion facing 7 exceeds 90%, the movable wedge member 25 will not bend.
また第６図に見られるように、平角材３１は平
角材２９が構成する溝に案内されることから、可
