SHEET MATERIAL BEND FORMING MACHINE |
摘要 |
The mold is secured on the bed portion, and the frame is moved up and down by the jack devices so that the rubber sheet is moved down to the mold and moved up from the mold in a reciprocating motion. While setting the work W, the rubber sheet is stretched by the sheet stretching devices for absorbing the deflection of the rubber sheet, thereby the possibility of the dislocation of the work W on the mold due to the contact with the rubber sheet is reduced, and the insertion of the work between the rubber sheet and the mold becomes easy. Both edge portions of the rubber sheet extending beyond the edge of the mold are clipped by the convex portion formed on the bed portion and the concave portion formed on the frame, thereby the wrinkling of the rubber sheet hardly occurs. |
