鋼板の折り曲げ作業でドアー、パネル製作工程
の曲げ工程の無人化を図るものでこのうち、多種
の型の交換をNC装置等の指令により、自動的に
型交換出来る曲げ装置に関する。[Detailed Description of the Invention] This technology aims to automate the bending process in the door and panel manufacturing process in the bending work of steel plates, and among these, the bending process allows automatic mold replacement by commands from an NC device, etc. Regarding equipment.
ドアー、パネル類は、標準化され、外形・折り
曲げ形状、寸法は統一化の方向にあるが、ほんの
一部であり、その都度仕様に合わせざるを得ない
のが実態である。 Doors and panels are becoming standardized, and their external shapes, folding shapes, and dimensions are becoming more unified, but only a small portion of them are being standardized, and the reality is that they have to be adapted to specifications each time.
従つて、製品の折り曲げ長さに適合した長さの
型、更に曲げＲに応じた断面別の型が必要であ
り、多くの型を保有する必要がある。 Therefore, it is necessary to have a mold with a length that matches the bending length of the product, and a mold with a different cross section depending on the bending radius, and it is necessary to have a large number of molds.
この為、型の交換頻度が高いのが実態である。

る。 For this reason, the actual situation is that molds are replaced frequently.
Conventionally, when fixing the upper die to the ram of the press body, a suitable die was selected and attached to the die mounting plate attached to the ram using bolts or an air clamp device, but in the case of long pieces ( 2300〜
2500), the mold is heavy, requires many man-hours for transportation, centering, tightening, etc., and most of the bending work is spent changing the mold, which is also dangerous work.
