スプリングパッド１Ｂは固定下型１２の上段面に合致す
べく形成されている。Conventionally, as a device for performing oblique bending of decorative boards, etc., there are devices shown in FIGS. 5 and 6, namely,
11 is a base; 12 is a fixed lower mold having a substantially stepped molding surface disposed horizontally on the base; 13 is the circumferential lower mold 12;
An upper mold holder 15 and 16 is disposed above the upper mold holder so as to be movable up and down via a fluid pressure cylinder 14, and 15 and 16 are fixed upper molds and spring pads arranged downwardly in parallel on the lower surface of the upper mold holder 13. The mold 15 is formed in a relative shape to match the lower stage surface and the inclined surface of the molding surface of the fixed lower mold 12, and
The spring pad 1B is formed to match the upper surface of the fixed lower mold 12.

より上型ホルダー１３を上昇せしめ、固定上型１５及び
スプリングパッド１６を原状に復帰せしめる。As shown in FIG. 5, the bending apparatus configured as described above first places the workpiece A of a required length on the molding surface using the upper surface of the fixed lower die 12 as a base. After that, the upper die holder is activated by the operation of the fluid pressure cylinder 14! 3 is lowered, and the work plate A is pressed and held by the spring pad IB against the upper surface of the fixed lower die 12, and the fixed upper die 15 is further lowered while contacting the work plate A, and then the fixed upper die The plate A to be processed is gradually bent as the fixed upper mold 15 descends, and the bending process of the plate A to be processed is completed when the fixed upper die 15 reaches the bottom dead center (see Fig. 6).
When the bending process is completed, the upper mold holder 13 is raised by the operation of the fluid pressure cylinder 14, and the fixed upper mold 15 and the spring pad 16 are returned to their original states.
以下、同様にして順次被加工板Ａの曲げ加工を行うもの
である。Thereafter, the workpiece A is sequentially bent in the same manner.
上記従来の曲げ加工装置は、簡単な構成でもって所要の
被加工板Ａを容易に曲げ加工することができる反面、被
加工板Ａの一端をスプリングパッド１Ｂにより押圧保持
せしめ、固定上型１５を自由端側に当接して擦りつつ下
方に押圧し。The above-mentioned conventional bending device has a simple configuration and can easily bend the required workpiece plate A, but on the other hand, one end of the workpiece plate A is pressed and held by the spring pad 1B, and the fixed upper die 15 is Press down while rubbing against the free end side.
固定下型１２に圧接することにより曲げ加工を行うもの
であるから１次の欠点を有する。Since the bending process is performed by pressing against the fixed lower mold 12, it has the following drawback.
まず第１に、固定上型１５の擦りに伴うスリ傷及びショ
ックラインが被加工板Ａ上面に生じやすく、しかも、所
謂ショックラインが曲げ個所とずれた位置に線状顕現し
、被加工板Ａの外面を損うものである。First of all, scratches and shock lines due to the rubbing of the fixed upper die 15 are likely to occur on the upper surface of the workpiece A, and moreover, the so-called shock lines appear in a linear form at a position shifted from the bending point, and the workpiece A It damages the external appearance of the
第２に、固定上型１５は被加工板Ａに当接して擦りつつ
下方に押圧するものであるから、固定上型１５の当接部
、即ち、成型面の角部を必然的にＲ形状にしなければな
らないものであって、鋭角的な曲げ加工をしずらいもの
である。Second, since the fixed upper mold 15 contacts and rubs the workpiece plate A while pressing downward, the contact portion of the fixed upper mold 15, that is, the corner of the molding surface, is inevitably rounded. It is difficult to bend sharply.
第３に、被加工板Ａの曲げ加工個所に孔が存在する場合
には固定上型１５の不均一な押圧力が加わり、歪みの出
ない曲げ加工が非常にしすらいものである。Thirdly, if there is a hole in the bending part of the workpiece A, uneven pressing force from the fixed upper mold 15 is applied, and the bending process without distortion is very easy.
この発明は、従来の問題点を一挙に解決し、スリ傷やシ
ョックラインに伴う線状傷を生じることなく確実に曲げ
